See |sponsor|. + + *known-bugs* +-------------------- Known bugs and current work ----------------------- + +GTK2: font dialog uses font size zero when 'guifont' is "Courier". Patch from +Yasuhiro Matsumoto, 2004 June 8. + +Python indent: # aser: still adds extra indent. + + +For version 7.0: +- Include many PATCHES: + - Include the kvim patch. http://freenux.org/vim/ (Mickael Marchand) + Do not add Qtopia yet, it doesn't work very well. +- new DATA TYPES: lists, dictionaries and function references. + Add type checking? See ~/vim/ideas.txt. +- Add SPELLCHECKER, with easy to add support for many languages. +- REFACTORING: The main() function is very long. Move parts to separate + functions, especially loops. Ideas from Walter Briscoe (2003 Apr 3, 2004 + Feb 9). +- Store messages to allow SCROLLING BACK for all commands. And other "less" + like commands. +- "INTELLISENSE". First cleanup the Insert-mode completion. + http://www.vim.org/scripts/script.php?script_id=747 + http://sourceforge.net/projects/insenvim +- PERSISTENT UNDO: store undo in a file. + Support multiple threads. Show the list of changes in a window to be able + to select a version. +7 SWAP FILE CHANGE: When a dos format file was edited with ":e ++ff=unix", + Vim is killed and trying to recover the file, 'ff' will be dos. Same for + non-default fileencoding. (Miroslaw Dobrzanski-Neumann, Jul 17) + Should store the values in block 0 of the swap file, but that is an + incompatible change. +7 Support WINDOW TABS. Works like several pages, each with their own + split windows. Patch for GTK 1.2 from Christian Michon, 2004 Jan 6. + Also for the console! +- EMBEDDING: Make it possible to run Vim inside a window of another program. + For Xwindows this can be done with XReparentWindow(). + For GTK Neil Bird has a patch to use Vim like a widget. +- Add COLUMN NUMBERS to ":" commands ":line1,line2[col1,col2]cmd". Block + can be selected with CTRL-V. Allow '$' (end of line) for col2. +- Add DEBUGGER INTERFACE. Implementation for gdb by Xavier de Gaye, + assisted by Mikolaj Machowski. Should work like an IDE. Try to keep it + generic. Also found here: http://skawina.eu.org/mikolaj/vimgdb + To be able to start the debugger from inside Vim: For GUI run a program + with a netbeans connection; for console: start a program that splits the + terminal, runs the debugger in one window and reconnect Vim I/O to the + other window. + Wishes for NetBeans commands: + - make it possible to have 'defineAnnoType' also handle terminal colors. + - send 'balloonText' events for the cursor position (using CursorHold ?) + in terminal mode. +- STICKY CURSOR: Add a way of scrolling that leaves the cursor where it is. + Especially when using the scrollbar. Typing a cursor-movement command + scrolls back to where the cursor is. + + +Vi incompatibility: +8 With undo/redo only marks in the changed lines should be changed. Other + marks should be kept. Vi keeps each mark at the same text, even when it + is deleted or restored. (Webb) + Also: A mark is lost after: make change, undo, redo and undo. + Example: "{d''" then "u" then "d''": deletes an extra line, because the '' + position is one line down. (Veselinovic) +8 ":change" in a single-line file adds an empty line. When the file used to + be longer a "~" line is displayed, but there really is an empty line. + (Haakon Riiser, 2003 Dec 3 and Dec 16) +8 ":append" and ":insert" in an empty file add an extra empty line. (Haakon + Riiser, 2003 Dec 3) Test for ML_EMPTY. +8 When stdin is not a tty, and Vim reads commands from it, an error should + make Vim exit. +7 Unix Vim (not gvim): Typing CTRL-C in Ex mode should finish the line + (currently you can continue typing, but it's truncated later anyway). + Requires a way to make CTRL-C interrupt select() when in cooked input. +8 When loading a file in the .exrc, Vi loads the argument anyway. Vim skips + loading the argument if there is a file already. When no file argument + given, Vi starts with an empty buffer, Vim keeps the loaded file. (Bearded) +6 In Insert mode, when using <BS> or <Del>, don't wipe out the text, but + only move back the cursor. Behaves like '$' in 'cpoptions'. Use a flag + in 'cpoptions' to switch this on/off. +8 When editing a file which is a symbolic link, and then opening another + symbolic link on the same file, Vim uses the name of the first one. + Adjust the file name in the buffer to the last one used? Use several file + names in one buffer??? + Also: When first editing file "test", which is symlink to "test2", and + then editing "test2", you end up editing buffer "test" again. It's not + logical that the name that was first used sticks with the buffer. +7 The ":undo" command works differently in Ex mode. Edit a file, make some + changes, "Q", "undo" and _all_ changes are undone, like the ":visual" + command was one command. +7 The ":map" command output overwrites the command. Perhaps it should keep + the ":map" when it's used without arguments? +7 CTRL-L is not the end of a section? It is for Posix! Make it an option. +7 Implement 'prompt' option. Init to off when stdin is not a tty. +7 CTRL-T in Insert mode inserts 'shiftwidth' of spaces at the cursor. Add a + flag in 'cpoptions' for this. +7 Add a way to send an email for a crashed edit session. Create a file when + making changes (containing name of the swap file), delete it when writing + the file. Supply a program that can check for crashed sessions (either + all, for a system startup, or for one user, for in a .login file). +7 Vi doesn't do autoindenting when input is not from a tty (in Ex mode). +7 "z3<CR>" should still use the whole window, but only redisplay 3 lines. +7 ":tag xx" should move the cursor to the first non-blank. Or should it go + to the match with the tag? Option? +7 Implement 'autoprint'/'ap' option. +7 Add flag in 'cpoptions' that makes <BS> after a count work like <Del> + (Sayre). +7 Add flag in 'cpoptions' that makes operator (yank, filter) not move the + cursor, at least when cancelled. (default Vi compatible). +7 Make "5dd" on last-but-one-line not delete anything (Vi compatible). + Add flag in 'cpoptions' for this. When not present, "2dd" in the last + line should delete the last line. Patch from greenx 2002 Apr 11. +7 This Vi-trick doesn't work: "Q" to go to Ex mode, then "g/pattern/visual". + In Vi you can edit in visual mode, and when doing "Q" you jump to the next + match. Nvi can do it too. +7 Support '\' for line continuation in Ex mode for these commands: (Luebking) + g/./a\ g/pattern1/ s/pattern2/rep1\\ + line 1\ line 2\\ + line 2\ line 3\\ + . line4/ +6 ":e /tmp/$tty" doesn't work. ":e $uid" does. Is $tty not set because of + the way the shell is started? +6 Vi compatibility (optional): make "ia<CR><ESC>10." do the same strange + thing. (only repeat insert for the first line). + + +GTK+ 1 (OK in GTK 2): +8 When menus are disabled, 'm' removed from 'guioptions', Alt-F still pops + up the File menu. Cannot reproduce this: gives a warning for a NULL + pointer if the menu was never displayed. +8 When using "gvim -geom 40x30" or setting 'columns' in .gvimrc or with a + GUIEnter autocommand, the width is still set to fit the toolbar. Also + happens when changing the font. How to avoid that the toolbar specifies + the minimal window width? +8 When using a theme with different scrollbars (gtkstep), the scrollbars can + be too narrow. (Drazen Kacar) +8 Font "7x14" has a bold version "7x14bold". Try to find the bold font by + appending "bold" when there are not 14 dashes. + +GTK+ GUI known bugs: +8 GTK 2: Combining UTF-8 characters not displayed properly in menus (Mikolaj + Machowski) They are displayed as separate characters. Problem in + creating a label? +9 Can't paste a Visual selection from GTK-gvim to vim in xterm or Motif gvim + when it is longer than 4000 characters. Works OK from gvim to gvim and + vim to vim. Pasting through xterm (using the shift key) also works. + It starts working after GTK gvim loses the selection and gains it again. +7 DND doesn't work with KDE (also with GTK 1). + + +Win32 GUI known bugs: +8 On Windows 98 the unicows library is needed to support functions with UCS2 + file names. Can we load unicows.dll dynamically? +8 The -P argument doesn't work very well with many MDI applications. + The last argument of CreateWindowEx() should be used, see MSDN docs. + Tutorial: http://win32assembly.online.fr/tut32.html +8 In eval.c, io.h is included when MSWIN32 is defined. Shouldn't this be + WIN32? Or can including io.h be moved to vim.h? (Dan Sharp) +7 Windows XP: When using "ClearType" for text smoothing, a column of yellow + pixels remains when typing spaces in front of a "D" ('guifont' set to + "lucida_console:h8"). +6 Win32 GUI: With "-u NONE -U NONE" and doing "CTRL-W v" "CTRL-W o", the ":" + of ":only" is highlighted like the cursor. (Lipelis) +7 When font smoothing is enabled, redrawing can become very slow. The reason + appears to be drawing with a transparent background. Would it be possible + to use an opaque background in most places? +8 Use another default for 'termencoding': the active codepage. Means that + when 'encoding' is changed typing characters still works properly. + Alternative: use the Unicode functions to obtain typed characters. +8 Win32: Multi-byte characters are not displayed, even though the same font + in Notepad can display them. (Srinath Avadhanula) Try with the + UTF-8-demo.txt page with Andale Mono. +7 The cursor color indicating IME mode doesn't work properly. (Shizhu Pan, + 2004 May 9) +8 Win32: When clicking on the gvim title bar, which gives it focus, produces + a file-changed dialog, after clicking on a button in that dialog the gvim + window follows the mouse. The button-up event is lost. Only with + MS-Windows 98? + Try this: ":set sw ts", get enter-prompt, then change the file in a + console, go back to Vim and click "reload" in the dialog for the changed + file: Window moves with the cursor! + Put focus event in input buffer and let generic Vim code handle it? +8 When activating the Vim window with mouse click, don't move cursor to + mouse position. Catch WM_MOUSEACTIVATE. (Luevelsmeyer) +9 The print dialog uses a font which doesn't display multi-byte messages. + Include patch from Vipin Aravind? Update from Yasuhiro Matsumoto. +8 Win32: When mouse is hidden and in the toolbar, moving it won't make it + appear. (Sami Salonen) +8 Windows NT: writing to aux.* makes Vim hang. (Acevedo) +8 Win32 GUI: With maximized window, ":set go-=r" doesn't use the space that + comes available. (Poucet) It works OK on Win 98 but doesn't work on Win + NT 4.0. Leaves a grey area where the scrollbar was. ":set go+=r" also + doesn't work properly. +8 When Vim is minimized and when maximizing it a file-changed dialog pops + up, Vim isn't maximized. It should be done before the dialog, so that it + appears in the right position. (Webb) +9 When selecting at the more-prompt or hit-enter-prompt, the right mouse + button doesn't give popup menu. + At the hit-enter prompt CTRL-Y doesn't work to copy the modeless + selection. + On the command line, don't get a popup menu for the right mouse button. + Let the middle button paste selected text (not the clipboard but the + non-Visual selection)? Otherwise CTRL-Y has to be used to copy the text. +8 When 'grepprg' doesn't execute, the error only flashes by, the + user can hardly see what is wrong. (Moore) + Could use vimrun with an "-nowait" argument to only wait when an error + occurs, but "command.com" doesn't return an error code. +8 When the 'shell' cannot be executed, should give an appropriate error msg. + Esp. for a filter command, currently it only complains the file could not + be read. +8 MessageBox used for error messages can be too big. There is no way to + scroll it, or even hit the OK button (but you can hit return). + Use a scrollable window. +7 Add an option to add one pixel column to the character width? Lucida + Console italic is wider than the normal font ("d" overlaps with next char). + Opposite of 'linespace': 'columnspace'. +7 At the hit-enter prompt scrolling now no longer works. Need to use the + keyboard to get around this. Pretend <CR> was hit when the user tries to + scroll? Need to be able to get out of hit-enter prompt with the mouse + anyway. +7 Scrollbar width doesn't change when selecting other windows appearance. + Also background color of Toolbar and rectangle below vert. scrollbar. +7 "!start /min cmd" should run in a minimized window, instead of using + "/min" as the command name. (Rogall) +6 Drawing text transparently doesn't seem to work (when drawing part cursor). +8 CTRL key doesn't always work in combination with ALT key. It does work + for function keys, not for alphabetic characters. Perhaps this is because + CTRL-ALT is used by Windows as AltGr? +8 CTRL-- doesn't work for AZERTY, because it's CTRL-[ for QWERTY. How do we + know which keyboard is being used? +7 When scrolling, and a background color is dithered, the dither pattern + doesn't always join correctly between the scrolled area and the new drawn + area (Koloseike). +8 When gui_init_font() is called with "*", p_guifont is freed while it might + still be used somewhere. This is too tricky, do the font selection first, + then set the new font by name (requires putting all logfont parameters in + the font name). + + +Athena and Motif: +9 Can configure be changed to disable netbeans if the Xpm library is + required and it's missing? +8 When using the resource "Vim*borderwidth 2" the widgets are positioned + wrong. +9 XIM is disabled by default for SGI/IRIX. Fix XIM so that 'imdisable' can + be off by default. +9 XIM doesn't work properly for Athena/Motif. (Yasuhiro Matsumoto) For now, + keep XIM active at all times when the input method has the preediting + flag. +8 X11: A menu that contains an umlaut is truncated at that character. + Happens when the locale is "C", which uses ASCII instead of IS0-8859-1. + Is there a way to use latin1 by default? Gnome_init() seems to do this. +8 Perhaps use fontsets for everything? +6 When starting in English and switching the language to Japanese, setting + the locale with ":lang", 'guifontset' and "hi menu font=", deleting all + menus and setting them again, the menus don't use the new font. Most of + the tooltips work though... +7 Motif: when using a file selection dialog, the specified file name is not + always used (when specifying a filter or another directory). +8 When 'encoding' is different from the current locale (e.g., utf-8) the + menu strings don't work. Requires conversion from 'encoding' to the + current locale. Workaround: set 'langmenu'. + + +Athena GUI: +9 When dragging the scrollbar thumb very fast, focus is only obtained in + the scrollbar itself. And the thumb is no longer updated when moving + through files. +7 The file selector is not resizable. With a big font it is difficult to + read long file names. (Schroeder) +4 Re-write the widget attachments and code so that we will not have to go + through and calculate the absolute position of every widget every time the + window is refreshed/changes size. This will help the "flashing-widgets" + problem during a refresh. +5 When starting gvim with all the default colors and then typing + ":hi Menu guibg=cyan", the menus change color but the background of the + pullright pixmap doesn't change colors. + If you type ":hi Menu guibg=cyan font=anyfont", then the pixmap changes + colors as it should. + Allocating a new pixmap and setting the resource doesn't change the + pullright pixmap's colors. Why? Possible Athena bug? + + +Motif GUI: +8 Popup menu ordering is wrong. +8 Accelerators don't work in a dialog. Include patch from Martin Dalecki + (Jan 3, tested by David Harrison). Should work with Alt-o then. +7 Use accelerators for the Motif file selection dialog. Patch from Martin + Dalecki 2002 Jan 11. +7 Use XmStringCreateLocalized() instead of XmStringCreateSimple()? + David Harrison says it's OK (it exists in Motif 1.2). +8 The texts in the find/replace dialog don't use the right font. +8 Lesstif: When deleting a menu that's torn off, the torn off menu becomes + very small instead of disappearing. When closing it, Vim crashes. + (Phillipps) + + +GUI: +9 On Solaris, creating the popup menu causes the right mouse button no + longer to work for extending the selection. (Halevy) +9 When running an external program, it can't always be killed with CTRL-C. + e.g. on Solaris 5.5, when using "K" (Keech). Other 'guipty' problems on + Solaris 2.6. (Marley) +9 On Solaris: Using a "-geometry" argument, bigger than the window where Vim + is started from, causes empty lines below the cmdline. (raf) +8 X11 GUI: When menu is disabled by excluding 'm' from 'guioptions', ALT key + should not be used to trigger a menu (like the Win32 version). +8 When setting 'langmenu', it should be effective immediately. Store both + the English and the translated text in the menu structure. Re-generate + the translation when 'langmenu' has changed. +8 Basic flaw in the GUI code: NextScreen is updated before calling + gui_write(), but the GUI code relies on NextScreen to represent the state + of where it is processing the output. + Need better separation of Vim core and GUI code. +8 When fontset support is enabled, setting 'guifont' to a single font + doesn't work. +8 Menu priority for sub-menus for: Amiga, BeOS. +8 Add menu separators for Amiga, RISCOS. +8 Add a few more command names. Patch from Jiri Brezina (28 feb 2002). +8 Add way to specify the file filter for the browse dialog. At least for + browse(). +8 Add dialog for search/replace to other GUIs? Tk has something for this, + use that code? Or use console dialog. +8 When selecting a font with the font dialog and the font is invalid, the + error message disappears too quick. +8 gui_check_colors() is not called at the right moment. Do it much later, + to avoid problems. +8 gui_update_cursor() is called for a cursor shape change, even when there + are mappings to be processed. Only do something when going to wait for + input. Or maybe every 100 ms? +8 X11: When the window size is reduced to fit on screen, there are blank + lines below the text and bottom scrollbar. "gvim -geometry 80x78+0+0". + When the "+0+0" is omitted it works. +8 When starting an external command, and 'guipty' set, BS and DEL are mixed + up. Set erase character somehow? +8 A dead circumflex followed by a space should give the '^' character + (Rommel). Look how xterm does this. + Also: Bednar has some code for dead key handling. + Also: Nedit 5.0.2 with USE_XMIM does it right. (Gaya) +8 The compose key doesn't work properly (Cepas). Both for Win32 and X11. +7 The cursor in an inactive window should be hollow. Currently it's not + visible. +7 GUI on Solaris 2.5.1, using /usr/dt/..: When gvim starts, cursor is + hollow, after window lowered/raised it's OK. (Godfrey) +7 When starting GUI with ":gui", and window is made smaller because it + doesn't fit on the screen, there is an extra redraw. +8 When setting font with .Xdefaults, there is an extra empty line at the + bottom, which disappears when using ":set guifont=<Tab>". (Chadzelek) +8 When font shape changes, but not the size, doing ":set font=" does not + redraw the screen with the new font. Also for Win32. + When the size changes, on Solaris 2.5 there isn't a redraw for the + remaining part of the window (Phillipps). +- Flashes really badly in certain cases when running remotely from a Sun. +4 Re-write the code so that the highlighting isn't changed multiple times + when doing a ":hi clear". The color changes happen three or more times + currently. This is very obvious on a 66Mhz 486. + + +MSDOS/DJGPP: +9 Pressing CTRL-C often crashes the console Vim runs in. (Ken Liao) + When 'bioskey' isn't set it doesn't happen. Could be a problem with the + BIOS emulation of the console. Version 5.6 already had this problem. +8 DJGPP: "cd c:" can take us to a directory that no longer exists. + change_drive() doesn't check this. How to check for this error? +9 The 16 bit version runs out of memory very quickly. Should find unused + code and reduce static data. +9 Crash when running on Windows 98 in a console window and pressing CTRL-C. + Happens now and then. When debugging Vim in gdb this also happens. Since + the console crashes, might be a bug in the DOS console. Resetting + 'bioskey' avoids it, but then CTRL-C doesn't work. +9 DOS: Make CTRL-Fx and ALT-Fx work. + CTRL-F1 = CE-5E, CTRL-F2 = CE-5F, .., CTRL-F10 = CE-67 + ALT-F1 = CE-68, ALT-F2 = CE-69, .., ALT-F10 = CE-71 + Shifted cursor keys produce same codes as unshifted keys. Use bioskey(2) + to get modifier mask for <S-C-M-Fx>. + Use K_SPECIAL/KS_MODIFIER codes to insert modifier mask in input stream? + Make this work like in Win32 console. + Mapping things like <M-A> doesn't work, because it generates an extended + key code. Use a translation table? +9 Can't read an opened swap file when the "share" command has not been used. + At least ignore the swap files that Vim has opened itself. +8 Use DJGPP 2.03. +8 The Dos32 version (DJGPP) can't use long file names on Windows NT. + Check if new package can be used (v2misc/ntlfn08[bs].zip). +8 setlocale() is bogus. +8 Vim busy waits for new characters or mouse clicks. Should put in some + sort of sleep, to avoid eating 50% of the CPU time. Test on an unpatched + Windows 95 system! +8 DJGPP: when shell is bash, make fails. (Donahoe) +7 Hitting CTRL-P twice quickly (e.g. in keyword completion) on a 8088 + machine, starts printer echo! (John Mullin). +7 MSDOS 16 bit version can't work with COMSPEC that has an argument, e.g.: + COMSPEC=C:\WINDOWS\COMMAND.COM /E:4096 (Bradley) + Caused by BCC system() function (Borland "make" has the same problem). +8 Mouse: handle left&right button pressed as middle button pressed. Add + modifier keys shift, ctrl and alt. +7 When too many files are open (depends on FILES), strange things happen. + The Dos16 version runs out of memory, in the Dos32 version "!ls" causes a + crash. Another symptom: .swp files are not deleted, existing files are + "[New file]". +7 DJGPP version doesn't work with graphics display mode. Switch to a mode + that is supported? +8 DJGPP: ":mode" doesn't work for many modes. Disable them. +8 DJGPP: When starting in Ex mode, shouldn't clear the screen. (Walter + Briscoe) + + +MSDOS, OS/2 and Win32: +8 OS/2: Add backtick expansion. Undefine NO_EXPANDPATH and use + gen_expand_wildcards(). +8 OS/2: Add clipboard support? See example clipbrd.exe from Alexander + Wagner. +8 OS/2: Add Extended Attributes support and define HAVE_ACL. +8 OS/2: When editing a file name "foo.txt" that is actually called FOO.txt, + writing uses "foo.txt". Should obtain the real file name. +8 Should $USERPROFILE be used instead of $HOMEDRIVE/$HOMEPATH? +8 Win32 console: <M-Up> and <M-Down> don't work. (Geddes) We don't have + special keys for these. Should use modifier + key. +8 Win32 console: caps-lock makes non-alpha keys work like with shift. + Should work like in the GUI version. +8 Environment variables in DOS are not case sensitive. Make a define for + STRCMP_ENV(), and use it when comparing environment var names. +8 Setting 'shellslash' has no immediate effect. Change all file names when + it is set/reset? Or only use it when actually executing a shell command? +8 When editing a file on a Samba server, case might matter. ":e file" + followed by ":e FILE" will edit "file" again, even though "FILE" might be + another one. Set last used name in buflist_new()? Fix do_ecmd(), etc. +8 ":mksession" generates a "cd" command where "aa\#bb" means directory "#bb" + in "aa", but it's used as "aa#bb". (Ronald Hoellwarth) +8 When a buffer is editing a file like "ftp://mach/file", which is not going + to be used like a normal file name, don't change the slashes to + backslashes. (Ronald Hoellwarth) + + +Windows 95: +8 Editing a file by it's short file name and writing it, makes the long file + name disappear. Setting 'backupcopy' helps. + Use FindFirstFile()->cAlternateFileName in fname_case() (George Reilly). +8 Doing wildcard expansion, will match the short filename, but result in the + long filename (both DJGPP and Win32). + + +Win32 console: +9 When editing a file by its short file name, it should be expanded into its + long file name, to avoid problems like these: (Mccollister) + 1) Create a file called ".bashrc" using some other editor. + 2) Drag that file onto a shortcut or the actual executable. + 3) Note that the file name is something like BASHRC~1 + 4) Go to File->Save As menu item and type ".bashrc" as the file name. + 5) Press "Yes" to indicate that I want to overwrite the file. + 6) Note that the message "File exists (add ! to override)" is displayed + and the file is not saved. + Use FindFirstFile() to expand a file name and directory in the path to its + long name. +8 Also implement 'conskey' option for the Win32 console version? Look at + how Xvi does console I/O under Windows NT. +7 Re-install the use of $TERM and support the use of different terminals, + besides the console. +8 Use of <altgr> modifier doesn't work? 5.3 was OK. (Garcia-Suarez/Guckes) +9 Mapping <C-S-Tab> doesn't work correctly. How to see the difference with + <C-S-i>? +9 tmpnam() uses file in root of file system: "\asdf". That doesn't work on + a Netware network drive. Use same function as for Win32 GUI? +8 In os_win32.h, HAVE_STRICMP and HAVE_STRNICMP are defined only if __GNUC__ + is not defined. Shouldn't that be the other way around? +8 ":winpos" doesn't work. Patch from Vipin Aravind. +7 Use SetConsoleCP() and SetConsoleOutputCP() to implement 'termencoding'? + Avoids that input and output work differently. Need to be restored when + exiting. + + +Amiga: +8 In mch_inchar() should use convert_input_safe() to handle incomplete byte + sequences. +9 In mch_expandpath() a "*" is to be expanded, but "\*" isn't. Remove + backslashes in result. +8 Executing a shell, only one option for 'shell' is separated. Should do + all options, using white space separation. + + +Macintosh: +9 Mac: The motion type is not stored on the clipboard. Using ":set + clipboard=unnamed" makes "yyp" work characterwise. (Michael DeMoney) +7 Loading the Perl library only works on OS/X 10.2 or 10.3, never on both. + Load the Perl library dynamically see Python sources file dynload_mac + (Jack) + dynamic linking: http://developer.apple.com/technotes/tn2002/tn2064.html +8 Inputting Unicode characters does not work in the terminal. They appear + to arrive as upper and lower bytes. (David Brown, 2004 April 17) +8 Typing Unicode characters doesn't work at all in the GUI. +8 Patch to add 'transparency' option. Disadvantage: it's slow. (Eckehard + Berns, 2004 May 9) http://ecki.to/vim-icns/TransBack.diff +8 Patches from "Rain Dog" Cucka: + - guifont selector (2002 Dec 15) + - scrollbar (2002 Dec 8) + - Quartz fonts (2002 Dec 8) +9 Problems in Carbon version for OS X: (Benji Fisher) + - keyboard shortcuts in the menus get lost. +8 The Vim/About menu doesn't work. +8 ":gui" doesn't fork. Enabling the code in gui.c to fork causes a SEGV. +8 Define vim_mkdir() for Macintosh. +8 Define mch_writable() for Macintosh. +9 When DiskLock is running, using a swap file causes a crash. Appears to be + a problem with writing a file that starts with a dot. (Giacalone) +9 On G3 Mac, OS version 8, control strip causes characters messed up when + scrolling (CTRL-L cleans it up). (Benji Fisher) +9 On G3 Mac, OS version 8, variable-speed scrolling doesn't work, after two + seconds of scrolling the screen freezes. (Benji Fisher) +9 In mac_expandpath() check that handling of backslashes is done properly. +8 Standard Mac shortcuts are missing. (Amerige) +8 Handling of non-fixed width fonts is wrong. (Amerige) + + +"Small" problems: +8 When an ":edit" is inside a try command and the ATTENTION prompt is used, + the :catch commands are always executed, also when the file is edited + normally. Should reset did_emsg and undo side effects. Also make sure + the ATTENTION message shows up. +9 When using ":e ++enc=foo file" and the file is already loaded with + 'fileencoding' set to "bar", then do_ecmd() uses that buffer, even though + the fileencoding differs. Reload the buffer in this situation? Need to + check for the buffer to be unmodified. +8 ":g//" gives "Pattern not found error" with E486. Should not use the + error number, it's not a regular error message. +7 Vimtutor leaves escape sequence in terminal. This is the xterm response to + requesting the version number. (Yasuhiro Matsumoto) +8 When redirecting and using ":silent" the current column for displaying and + redirection can be different. Use a separate variable to hold the column + for redirection. +7 There is no way to change directory and go back without changing the local + and/or global directory. Add a way to find out if the current window uses + a local directory. Add cdcmd() that returns ":cd" or ":lcd"? +7 After running "make test" the window title is sometimes not restored. + Mostly sticks at "test3.in", but not always. Appears to happen more often + when compiled with Python (threading). +7 The messages for "vim --help" and "vim --version" don't use + 'termencoding'. +7 ATTENTION dialog choices are more logical when "Delete it' appears before + "Quit". Patch by Robert Webb, 2004 May 3. +8 When 'scrollbind' is set, a window won't scroll horizontally if the cursor + line is too short. Add a word in 'scrollopt' to allow moving the cursor + to longer line that is visible. A similar thing is done for the GUI when + using the horizontal scrollbar. +7 VisVim can only open one file. Hard to solve: each opened file is passed + with a separate invocation, would need to use timestamps to know the + invocations belong together. +8 When giving a ":bwipeout" command a file-changed dialog may popup for this + buffer, which is pointless. (Mike Williams) +8 On MS-Windows ":make" doesn't show output while it is working. Use the + tee.exe from http://unxutils.sourceforge.net/ ? About 16 Kbyte in the + UnxUtils.zip archive. + Alternate one: http://www.pramodx.20m.com/tee_for_win32.htm, but Walter + Briscoe says it's not as good. +8 'fillchars' doesn't work for multi-byte characters. +9 Editing a XML file with a long line is extremely slow. Example file from + Randy Parker (Dec 13). Editing the dictionaries for engspchk plugin with + syntax highlighting is also very slow. + Limit the searching for items to a few hundred characters? +8 Command line completion: buffers "foo.txt" and "../b/foo.txt", completing + ":buf foo<Tab>" doesn't find the second one. (George V. Reilly) +7 Output for ":scriptnames" and ":breaklist" should shorten the file names: + use "~/" when possible. +8 After using diff mode, ":set nodiff" doesn't restore the old foldmethod. + (Thomas S. Urban) +7 mb_off2cells() doesn't work correctly on the tail byte of a double-byte + character. (Yasuhiro Matsumoto) It should return 1 when used on a tail + byte, like for utf-8. Store second byte of double-byte in ScreenLines2[] + (like for DBCS_JPNU) and put a zero in the second byte (like for UTF-8). +8 'backupdir' and 'directory' should use $TMPDIR, $TMP and/or $TEMP when + defined. +7 Inside a function with "perl <<EOF" a line with "$i++" is recognized as an + ":insert" command, causing the following "endfunction" not to be found. + Add skipping this perl construction inside function definitions. +7 When 'ttimeoutlen' is 10 and 'timeoutlen' is 1000, there is a keycode + "<Esc>a" and a mapping <Esc>x", when typing "<Esc>a" with half a second + delay should not be interpreted as a keycode. (Hans Ginzel) +7 ":botright 1 new" twice causes all window heights to be changed. Make the + bottom window only bigger as much as needed. +7 "[p" doesn't work in Visual mode. (David Brown) +7 The Cygwin and MingW makefiles define "PC", but it's not used anywhere. + Remove? (Dan Sharp) +9 The argument <f-args> of a user command doesn't handle backslashes + properly. "Cmd \ e" is one argument, "Cmd \\ e" still is one argument. + "Cmd \ e" is two arguments, first one ending in space. (Kontra Gergely) +9 User commands use the context of the script they were defined in. This + causes a "s:var" argument to unexpectedly use a variable in the defining + script, not the calling script. Add an argument to ":command": + "-keepcontext". Do replace <SID>, so that a function in the defining + script can be called. +8 The Japanese message translations for MS-Windows are called ja.sjis.po, + but they use encoding cp932. Rename the file and check that it still + works. +9 When a syntax region does not use "keepend" and a contained item does use + "extend", this makes the outer region stop at the end of the contained + region. (Lutz Eymers) Another example Nov 14 2002. +8 A very long message in confirm() can't be quit. Make this possible with + CTRL-C. +7 clip_x11_own_selection() uses CurrentTime, that is not allowed. VNC X + server has a problem with this. (Mark Waggoner) Remembering the timestamp + of events isn't always possible. We don't get them in an xterm. GTK + doesn't obtain the selection again when the timestamp differs, thus it + won't work for GTK anyway. +8 When the clipboard isn't supported: ":yank*" gives a confusing error + message. Specifically mention that the register name is invalid. +8 "gf" always excludes trailing punctuation characters. file_name_in_line() + is currently fixed to use ".,:;!". Add an option to make this + configurable? +8 'hkmap' should probably be global-local. +9 When "$" is in 'cpoptions' and folding is active, a "C" command changes + the folds and resets w_lines_valid. The display updating doesn't work + then. (Pritesh Mistry) +8 ":s!from!to!" works, but ":smagic!from!to!" doesn't. It sees the "!" as a + flag to to the command. Same for ":snomagic". (Johan Spetz) +8 Using ":s" in a function changes the previous replacement string. Save + "old_sub" in save_search_patterns()? +8 When appending to a file and 'patchmode' isn't empty, a backup file is + always written, even when the original file already exists. +7 When using "daw" on the last word in a file and this is a single letter, + nothing is deleted. Should delete the letter and preceding white space. +9 When getting focus while writing a large file, could warn for this file + being changed outside of Vim. Avoid checking this while the file is being + written. +9 The "Error detected while processing modelines" message should have an + error number. +7 The message in bt_dontwrite_msg() could be clearer. +8 Unix: When libcall() fails there is no clear error message. Johannes + Zellner has a patch for this. +8 The script ID that is stored with an option and displayed with ":verbose + set" isn't reset when the option is set internally. For example when + 'foldlevel' is set from 'foldlevelstart'. +8 In the fileformat dialog, "Cancel" isn't translated. Add a global + variable for this. (Eduardo Fernandez) +9 When editing a file with 'readonly' set, there is no check for an existing + swap file. Then using ":write" (without making any changes) doesn't give + a warning either. Should check for an existing swap file without creating + one. +7 On MS-DOS or MS-Windows, when editing the same file over a network, the + drive letter is different, thus an existing swap file doesn't generate a + warning. Use some flag to indicate the swap file is in the same directory + as the original file? Could make b0_fname[] start with a special + character like ">". +7 When 'showbreak' is set, the amount of space a Tab occupies changes. + Should work like 'showbreak' is inserted without changing the Tabs. +7 When there is a "help.txt" window in a session file, restoring that + session will not get the "LOCAL ADDITIONS" back. +7 When 'mousefocus' is set and switching to another window with a typed + command, the mouse pointer may be moved to a part of the window that's + covered by another window and we lose focus. Only move in the y + direction, not horizontally? +8 When using CTRL-D after ":help", restrict the number of matches to a + thousand, otherwise using CTRL-D without an argument takes too long. +8 ":hardcopy": + - Patch to append CTRL-D to PostScript output (Mike Williams, 2004 Jun 11) + - Using the cterm_color[] table is wrong when t_colors is > 16. + - Need to handle unprintable characters. + - Win32: On a B&W printer syntax highlighting isn't visible. Perform + dithering to make grey text? + - support printing multi-byte characters. Patch from Motonobu Ichimura. + New (better) patch from Mike Williams (2004 Jan 20) + - Add a flag in 'printoptions' to add an empty page to make the total + number even. "addempty"? (Mike Williams) + - Should interpreted CTRL-L as a page break. + - Grey line numbers are not always readable. Add field in 'printoptions'. + Default to black when no syntax highlighting. + - Be able to print a window in diff mode. + - Be able to specify a colorscheme to use for printing. And a separate + one for B&W printing (if that can be detected). +8 In Visual block mode with 'lbr' set, a change command doesn't insert the + text in following lines where the linebreak changes. +9 dosinst.c: The DJGPP version can't uninstall the Uninstall registry key on + Windows NT. How to install a .inf file on Windows NT and how to detect + that Windows NT is being used? +8 When opening the same file on Unix and on MS-Windows, there is no + ATTENTION message, because the path in the swap file is different. Using + a relative path name will cause no ATTENTION for Vim 5.8. + Somehow add a flag that the swap file is in the same dir as the file? +8 When 'virtualedit' is "block,insert" and encoding is "utf-8", selecting a + block of one double-wide character, then "d" deletes only half of it. +8 When 'virtualedit' is set, should "I" in blockwise visual mode also insert + in lines that don't extend into the block? +8 With 'virtualedit' set, in Insert mode just after the end of line, CTRL-O + yh does not yank the last character of the line. (Pavel Papushev) + Doing "hl" first appears to make it work. +8 With 'virtualedit' set it's possible to move into the blank area from + 'linebreak'. +8 With 'virtualedit' set and 'selection' "exclusive", a Visual selection + that ends in or after a tab, "d" doesn't delete (part of) the tab. + (Helmut Stiegler) +8 With 'virtualedit' set, a blockwise Visual selection that starts and ends + in a tab, "<" shifts too much. (Helmut Stiegler) +9 When jumping to a tag, the search pattern is put in the history. When + 'magic' is on, the pattern may not work. Translate the pattern depending + on p_magic when putting it in the history? Alternative: Store value of + 'magic' in history. (Margo) +9 optwin.vim: Restoring a mapping for <Space> or <CR> is not correct for + ":noremap". Add "mapcmd({string}, {mode})? Use code from ":mkexrc". +9 incsearch is incorrect for "/that/<Return>/this/;//" (last search pattern + isn't updated). +9 term_console is used before it is set (msdos, Amiga). +9 Get out-of-memory for ":g/^/,$s//@/" on 1000 lines, this is not handled + correctly. Get many error messages while redrawing the screen, which + cause another redraw, etc. +8 [<C-I> doesn't work when '*' is in 'iskeyword'. find_pattern_in_path() + must escape special characters in the pattern. +8 Vim can overwrite a read-only file with ":w!". ":w" can't overwrite an + existing file, "w!" can, but perhaps not a read-only file? Then use + ":w!!" for that. + Or ask for permission to overwrite it (if file can be made writable) and + restore file to readonly afterwards. +7 When compiled with "xterm_clipboard", startup can be slower and might get + error message for invalid $DISPLAY. Try connecting to the X server in the + background (forked), so that Vim starts up quicker? Connect as soon as + the clipboard is to be used (Visual select mode starts, paste from + clipboard) +7 X11: Some people prefer to use CLIPBOARD instead of PRIMARY for the normal + selection. Add an "xclipboard" argument to the 'clipboard' option? (Mark + Waggoner) +8 For xterm need to open a connection to the X server to get the window + title, which can be slow. Can also get the title with "<Esc>[21t", no + need to use X11 calls. This returns "<Esc>]l{title}<Esc>\". +8 When the builtin xterm termcap contains codes that are not wanted, need a + way to avoid using the builtin termcap. +8 Xterm sends ^[[H for <Home> and ^[[F for <End> in some mode. Also + recognize these keys? Mostly useful for xterm simulators, like gnometerm. + See http://dickey.his.com/xterm/xterm.faq.html#xterm_pc_style. +8 '[ and '] should be set to start/end of line when using a linewise operator + (e.g., ":w"). +8 CTRL-A can't handle big "long" numbers, they become negative. Check for + "-" character, if not present, use unsigned long. +8 Make it possible to disable the special meaning of "#" in the first column + for ">>". +8 Add suspending with CTRL-Z at the "more" prompt, and when executing a long + script in do_cmdline(). +8 When using 'hidden', many swap files will be open. When Vim runs into the + maximum number of open files, error messages will appear. Detect that + this problem is present, and close any hidden files that don't have + changes. +8 With 'viminfo' set such that the ".viminfo" file is written on a FAT + filesystem, an illegal file name may be created: ".vim". +8 For each buffer that is opened, the viminfo file is opened and read to + check for file marks. This can be slow. +7 In xterm, recognize both vt100 and vt220 cursor keys. Change + add_termcode() to not remove an existing entry for a name, when it's + needed. + Need a generic solution to recognize different codes for the same key. +8 Core dump within signal function: gdb doesn't show stack backtrace! Option + to skip catch_signals()? +9 Repeating a "cw" with "." doesn't work if the text was pasted from the + clipboard. (Thomas Jones) It's because the menu/toolbar item exits Insert + mode and uses "gP". How to fix this without breaking inserting a block of + text? +8 In Replace mode pasting from the clipboard (using menu or toolbar) inserts + all the text. Add ":rmenu"? +8 Pasting with the mouse in Replace mode inserts the text, instead of + overwriting, when it is more than one line. Same for using <C-R>. +9 CTRL-E and CTRL-Y don't work in small window when 'so' is 4 and lines are + wrapping (Acevedo/in.226). E.g., when using CTRL-E, window height 7, + window might actually scroll down when last line of buffer is displayed. + --> Remember if the previous command was "cursor follows screen" or + "screen follow cursor" and use this in cursupdate(). +7 tilde_replace() can only handle "~/", should also do "~user/". + Get the list of home directories (from /etc/passwd? Use getpwent()) and + use some clever algorithm to match a path with that. Find common strings + in the list? +8 When dragging status line with mouse, sometimes a jump when first clicking + on the status line (caused by 'winheight'). Select window on button up, + instead of on button down. +8 Dragging the status line doesn't scroll but redraw. +9 Evaluating 'statusline' in build_stl_str_hl() does not properly check for + reaching the end of the available buffer. +8 When performing incremental search, should abort searching as soon as a + character is typed. +8 When the value of $MAKE contains a path, configure can't handle this. + It's an autoconf bug. Remove the path from $MAKE to work around it. +8 How to set VIMRC_FILE to \"something\" for configure? Why does this not + work: CFLAGS='-DVIMRC_FILE=\"/mydir/myfile\"' ./configure +8 The temporary file is sometimes not writable. Check for this, and use an + alternate name when it isn't. Or add the 'temptemplate' option: template + for the temp file name ":set temptemplate=/usr/tmp/?????.tmp". + Also: Win32 version uses Windows temp directory, which might not work for + cygwin bash. +7 Get error "*, \+ or \( operand could be empty" for pattern "\(.\)\1\{3}". + Remember flags for backreferences. +7 When switching to Daylight Saving Time, Vim complains that a file has been + changed since last read. Can we use a function that uses GMT? +7 When completing an environment variable after a '$', check for file names + that contain a '$' after all have been found. +8 When "cm" termcap entry is missing, starting gvim shouldn't complain about + it. (Lohner) Try out with "vt100" entry, cm replaced with cX. +7 When an include file starts with "../", the check for already visiting + this file doesn't work. Need to simplify the file name. +8 On Sinix SYS_NMLN isn't defined. Include patch from Cristiano De Michele. +7 The names and comments for the arguments of do_browse() are confusing. + "dflt" isn't the default file name when "initdir" is not NULL and + "initdir" is the default path to be used. +7 When 'scrolloff' is exactly half the window height, "j" causes a scroll of + two lines at a time. "k" doesn't do this. (Cory T. Echols) +8 When write_viminfo() is used while there are many orphaned viminfo + tempfiles writing the viminfo file fails. Give a clear error message so + that the user knows he has to delete the files. +7 It's possible to redefine a script-local function with ":func + <SNR>123_Test()". (Krishna) Disallow this. +7 After ":%d" an undo reports the number of lines added as if there still + was one line. + + +I can't reproduce these (if you can, let me know how!): +9 NT 4.0 on NTFS file system: Editing ".bashrc" (drag and drop), file + disappears. Editing ".xyz" is OK. Also, drag&drop only works for three + files. (McCollister) +8 Motif: Tear-off menu item crashes Vim on some machines. (Netherton) It + works fine for me, maybe it's a Motif problem. + + +Problems that will (probably) not be solved: +- In a terminal with 'mouse' set such that the mouse is active when entering + a command line, after executing a shell command that scrolls up the + display and then pressing ":": Selecting text with the mouse works like + the display wasn't scrolled. Vim doesn't know how much the external + command scrolled up the display. Use Shift to select text. +- X windows: When $DISPLAY points to a X server where there is no access + permission, trying to connect to the X server causes an error message. + XtOpenDisplay() prints this directly, there is no way to avoid it. +- X windows: Setting 'guifontset' to an illegal value sometimes crashes Vim. + This is caused by a fault in a X library function, can't be solved in Vim. +- Motif: When adding a menu item "Find this &Symbol", the "s" in "this" will + be underlined, instead of in "Symbol". Motif doesn't let us specify which + character gets the highlighting. +- Moving the cursor removes color in color-xterm. This is a color-xterm + problem! color-xterm ver. 6.1 beta 3 and later work properly. +- In zsh, "gvim&" changes the terminal settings. This is a zsh problem. + (Jennings) +- Problem with HPterm under X: old contents of window is lost (Cosentino). +- Amiga: When using quickfix with the Manx compiler we only get the first 25 + errors. How do we get the rest? +- Amiga: The ":cq" command does not always abort the Manx compiler. Why? +- Linux: A file with protection r--rw-rw- is seen readonly for others. The + access() function in GNU libc is probably wrong. +- MSDOS: When using smartdrive with write-back buffering, writing to a + readonly floppy will cause problems. How to test for a writable floppy + first? +- MSDOS: Both 16 and 32 bit versions: File name expansion doesn't work for + names that start with a dot. These used to be illegal file names. +- When doing a CTRL-Z and typing a command for the shell, while Vim is busy + (e.g. writing a file), the command for the shell is sometimes eaten by Vim, + because the terminal mode is changed from RAW to CBREAK. +- An old version of GNU tgoto can't handle the terminfo code for "AF". The + "%p1" is interpreted as "%p" and "1", causing color not to be working. + Fix: Change the "%p1" in the "AF" and "AB" terminfo entries to "%p". + (Benzinger). +- When running an external command from the GUI, typeahead is going to that + program, not to Vim. It looks like the shell eats the characters, Vim + can't get back what the external command didn't use. +- Win32 GUI: Error code from external command not returned in shell_error. + It appears that cmd.exe and command.com don't return an error code. +- Win32 GUI: The Toolbar is a bit too high when the flat style is being + used. We don't have control over the height of the Toolbar. +- Win32: All files created on the day of switching from winter to summer + time cause "changed since editing started" messages. It goes away when + the file is written again the next day, or the timezone is adjusted. + DJGPP version is OK. (Zaimi) Looks like a problem with the Win32 library. + Rebooting doesn't help. Time stamps look OK in directory. (Penn) + Is this on FAT (stores wall clock time) or NTFS (stores UTS)? +- Win32, MS-Windows XP: $HOME uses the wrong drive when the user profiles + are not on the boot disk. This is caused by a wrong value of $HOMEDRIVE. + This is a bug in XP, see MSKB article 818134. +- SunOS 5.5.1 with Motif: The file open dialog does not have a horizontal + scroll bar for the "files" selection. This is a problem in the Motif + libraries, get a patch from Sun. +- Solaris 2.6 with GTK and Perl: gvim crashes when started. Problem with X + input method called from GDK code. Without Perl it doesn't crash. +- VMS: Vimdiff doesn't work with the VMS diff, because the output looks + different. This makes test 47 fail. Install a Unix-compatible diff. +- VMS v7.1 and older: Tests 21 and 32 fail. From VMS v7.1-2 and newer Vim + does not have this behavior. (Zoltan Arpadffy) +- Win32 GUI: mouse wheel always scrolls rightmost window. The events arrive + in Vim as if the rightmost scrollbar was used. +- GTK with Gnome: Produces an error message when starting up: + Gdk-WARNING **: locale not supported by C library + This is caused by the gnome library gnome_init() setting $LC_CTYPE to + "en_US". Not all systems support this locale name, thus causing the + error. Hopefully a newer version of GTK/Gnome fixes this problem. +- GTK 2: With this mapping the hit-enter prompt is _sometimes_ below the + screen, at other times there is a grey area below the command line: + :nmap <F11> :if &guioptions=~'m' \| set guioptions-=m \| else \| set guioptions+=m \| endif<cr> +- GTK: When pasting a selection from Vim to xclipboard gvim crashes with a + ABRT signal. Probably an error in the file gdkselection.c, the assert + always fails when XmbTextListToTextProperty() fails. (Tom Allard) +- When using an xterm that supports the termresponse feature, and the 't_Co' + termcap option was wrong when Vim started, it will be corrected when the + termresponse is received. Since the number of colors changes, the + highlighting needs to be initialized again. This may cause colors defined + in the vimrc file to be lost. +- On Windows NT 4.0 the number of files passed to Vim with drag&drop and + "Edit with Vim" is limited. The maximum command line length is 255 chars. + +--------------------- extensions and improvements ---------------------- + *extensions-improvements* + +Documentation: +8 Extend usr_27.txt a bit. (Adam Seyfarth) +9 Merge in ideas from ~/vim/patches/tutor.txt (Gabriel Zachmann) +7 Add a section on debugging scripts in the user manual. +9 Make the Reference Manual more precise. For each command mention: + - change to cursor position and curswant + - if it can be undone (u/CTRL-R) and redone (.) + - how it works for folded lines + - how it works with multi-byte characters +9 In change.txt, remark about Javadoc isn't right. Right alignment would + work too. +8 Spread the windows commands over the other files. For example, ":stag" + should be with ":tag". Cross-link with tags to avoid too much double + text. +8 Add tags for all features, e.g. "gui_running". +7 MS-Windows: When a wrong command is typed with an ALT key, give a hint to + look at the help for 'winaltkeys'. +7 Add a help.vim plugin that maps <Tab> to jump to the next tag in || and + <C-Tab> (and <S-Tab>) to the previous tag. +- Check text editor compendium for vi and Vim remarks. + + +Help: +- First try using the ":help" argument literally, before using it as a + pattern.

(Guckes) Use "~/.vimhelp" file, + user can edit it to insert his favorite commands, new account can contain a + default contents. +- Make 'winminheight' a local option, so that the user can set a minimal + height for the help window (and other windows). +- ":help :s^I" should expand to ":help :substitute". +- Make the help key (<F1>) context sensitive? +- Learn mode: show short help while typing commands. + + +User Friendlier: +8 Windows install with install.exe: Use .exe instead of .bat files for + links, so that command line arguments are passed on unmodified? (Walter + Briscoe) +8 Windows install: Be able to associate Vim with a selection of file types? +8 Windows uninstall: Have uninstal.c delete the vimfiles directories that + dosinst.c creates.

Let the user select a directory from + 'runtimepath'. + " Vim plugin + <main plugin code> + " >>> plugin help start <<< + <plugin docs> +- Add mappings local to a window: ":map <window> ..."? +9 Add buffer-local menu. Should offer a choice between removing the menu or + disabling it. Be careful that tear-offs don't disappear (keep one empty + item?). + Alternative: use BufEnter and BufLeave autocommands. +8 Add file locking. Lock a file when starting to edit it with flock() or + fcntl(). This patch has advisory file locking while reading/writing the + file: ~/vim/patches/kahn_file_locking . +8 make a vimtutor script for Amiga and other systems. +7 Add the arguments for configure to the ":version" output? + + +Diff mode: +8 Add a command to stop diff mode: ":set nodiff fdc = 0 noscrollbind" +8 Use diff mode to show the changes made in a buffer (compared to the file). + Use an unnamed buffer, like doing: + new | set bt=nofile | r # | 0d_ | diffthis | wincmd p | diffthis +7 Add cursor-binding: when moving the cursor in one diff'ed buffer, also + move it in other diff'ed buffers, so that CTRL-W commands go to the same + location. + + +Folding: + (commands still available: zg zG zI zJ zK zp zP zq zQ zV zw zW zy zY; + secondary: zB zS zT zZ) +8 Add different highlighting for a fold line depending on the fold level. + (Noel Henson) +8 When a closed fold is displayed open because of 'foldminlines', the + behavior of commands is still like the fold is closed. How to make the + user aware of this? +8 Add an option 'foldskip' with values like 'foldopen' that specifies which + commands skip over a closed fold. +8 "H" and "L" count buffer lines instead of window lines. (Servatius Brandt) +8 Add a way to add fold-plugins. Johannes Zellner has one for VB. +7 When using 2html.vim, also reproduce folds as you can see them.

How to + implement this? +- "zJ" command: add the line or fold below the fold in the fold under the + cursor. +- 'foldmethod' "syntax": "fold=3": set fold level for a region. +- Can set 'foldtext' to empty string: don't display any line. How to + implement this? +- Apply a new foldlevel to a range of lines. (Steve Litt) +- Have some way to restrict commands to not folded text. Also commands like + searches. + + +Multi-byte characters: +9 When the tail byte of a double-byte character is illegal (e.g., a CR), the + display is messed up (Yasuhiro Matsumoto). Should check for illegal + double-byte characters and display them differently (display each single + byte). +8 Add an item in 'fileencodings' to check the first lines of a file for + the encoding. See Python PEP: http://www.python.org/peps/pep-0263.html. + To avoid getting a wrong encoding only accept something Emacs-like: + "-*- coding: enc-na_me.foo -*-" and "-*- coding= enc-na_me.foo -*-" + Match with "-\*-\s*coding[:=]\s*\([::word::-_.]\+\)\s*-\*-" and use first + item. +8 Add an item in 'fileencodings' to check the first line of an XML file for + the encoding. <?xml version="1.0" encoding="UTF-8"?> Or "charset=UTF-8"? +8 The quickfix file is read without conversion, thus in 'encoding'. Add an + option to specify the encoding of the errorfile and convert it. Also for + ":grep". +8 When a file was converted from 'fileencoding' to 'encoding', a tag search + should also do this on the search pattern. (Andrzej M. Ostruszka) +7 When converting a file fails, mention which byte could not be converted, + so that the user can fix the problem. +8 Add configure option to be able to disable using the iconv library. (Udo + Schweigert) +8 Add patch from Muraoka Taro (Mar 16) to support input method on Mac? +9 'aleph' should be set to 1488 for Unicode. (Zvi Har'El) +8 Should add test for using various commands with multi-byte characters. +- Include flipcase patch: ~/vim/patches/wall.flipcase2 ? Make it work for + multi-byte characters. +8 'infercase' doesn't work with multi-byte characters. +8 toupper() function doesn't handle byte count changes. +8 Support four composing characters, needed for Hebrew. (Ron Aaron) +8 "ga" should show all composing characters, also if there are more than 2. +7 When searching, should order of composing characters be ignored? +8 Should implement 'delcombine' for command line editing. +8 Detect overlong UTF-8 sequences and handle them like illegal bytes. +8 ":s/x/\u\1/" doesn't work, making uppercase isn't done for multi-byte + characters. +8 UTF-8: "r" in Visual mode doesn't take composing characters. +8 UTF-8: When there is a precomposed character in the font, use it instead + of a character and a composing character. See xterm for an example. +7 When a character can't be displayed, display its digraph instead. + 'display' option to specify this. +7 Use ideas for nl_langinfo() from Markus Kuhn in enc_default(): + (www.cl.cam.ac.uk/~mgk25/ucs/langinfo.c) +- GTK and Win32: Allow selecting fonts for 'guifontset' with the + fontselector somehow. +- GTK and Win32: make it possible to set the font for the menu to make it + possible to have 'encoding' different from the current locale. +- dbcs_class() only works for Japanese and Korean. Implement this for + other encodings. The "euc-jp" and "euc-kr" choices might be wrong. +- Find some way to automatically select the right GUI font or fontset, + depending on the default value of 'encoding'. + Irrelevant in the GTK+ 2 GUI so long as UTF-8 is used. + For Windows, the charset_pairs[] table could be used. But how do we know + if a font exists? +- Do keyboard conversion from 'termencoding' to 'encoding' with + convert_input() for Mac GUI, RiscOS GUI, BeOS GUI. +- Add mnemonics from RFC1345 longer than two characters. + Support CTRL-K _{mnemonic}_ +7 In "-- INSERT (lang) --" show the name of the keymap used instead of + "lang". (Ilya Dogolazky) +- Make 'langmap' accept multi-byte characters. +- Do we need the reverse of 'keymap', like 'langmap' but with files and + multi-byte characters? E.g., when using a Russian keyboard. +- Add the possibility to enter mappings which are used whenever normal text + could be entered. E.g., for "f" command. But not in Normal mode. Sort + of opposite of 'langmap'. Use ":tmap" command? +- When breaking a line, take properties of multi-byte characters into + account. The "linebreak" program from Bruno Haible can do it: + ftp://ftp.ilog.fr/pub/Users/haible/gnu/linebreak-0.1.tar.gz + But it's very complicated... + + +Printing: +- Add "page width" to wrap long lines. +- Win32: use a font dialog for setting 'printfont'. Can reuse the code for + the 'guifont' dialog, put the common code in a separate function. +- Win32: when 'printfont' is empty use 'guifont'. +- Unix: Use some dialog box to do the obvious settings (paper size, printer + name, portrait/landscape, etc). +- Win32: add options to print dialog. Patch from Vipin Aravind. +- PostScript: only works for 7-bit ASCII and EBCDIC. Should support + different 'encoding' values somehow. +- Allow specifying the paper size, instead of using a standard size. Same + units as for the margins. +- Support right-to-left text? +8 Make the foreground color darkening function preserve the hue of the + color. + + +Syntax highlighting: +- Patch to add highlighting for whitespace. (Tom Schumm, 2003 Jul 5) + use the patch that keeps using HLF_8 if HLF_WS has not + been given values. + Add section in help files for these highlight groups? +8 Make ":syn off" use 'runtimepath' instead of $VIMRUNTIME. (Gary Johnson) + Should do the same for ":syn on" and ":syn manual". +8 Support "containedin" argument for ":syn include", so that the defined + cluster can be added to existing syntax items. +8 C syntax: Don't highlight {} as errors inside () when used like this: + "({ something })", often used in GCC code. +8 When editing a new file without a name and giving it a name (by writing + it) and 'filetype' is not set, detect the filetype. Avoid doing it for + ":wq file". +8 Make conversion to HTML faster (Write it in C or pre-compile the script). +9 There is still a redraw bug somewhere. Probably because a cached state is + used in a wrong way. I can't reproduce it... +7 Make syntax keyword table configurable. Set number of bits used with + ":syn clear [hashbits]", so that we don't need to reallocate the table. + minimal 4 bits, maximal 16. (Campbell) +7 Be able to change only the background highlighting. Useful for Diff* and + Search highlighting. +8 Allow the user to add items to the Syntax menu sorted, without having to + change this for each release. +8 Add a "matchcontains" for regions: items contained in the start or end + pattern, but not in the body. +8 Add a "keepend-contained" argument: Don't change the end of an item this + one is contained in. Like "keepend" but specified on the contained item, + instead of the containing item. +8 For keywords, allow to define the size of the hash table with ":syn + clear". Change KHASH_ defines into variables stored in buffer struct. + Use something else than linear linked list from the hash table. (Campbell) +8 cpp.vim: In C++ it's allowed to use {} inside (). +8 Some syntax files set 'iskeyword'. When switching to another filetype + this isn't reset. Add a special keyword definition for the syntax rules? + When this is done, use vim.vim syntax highlighting for help file examples, + but without ":" in 'iskeyword' for syntax. +8 Add specific syntax item to match with parens/braces that don't have a + "%" match. :syntax nomatch cMatchError (,{,[,),},] [contained] +8 Highlight the text between two matching parens (e.g., with a grey + background) when on one of the parens or in between them. + Or highlight the matching paren when the cursor is on one. +8 Add a command to jump to the next character highlighted with "Error". +8 When using a cterm, and no ctermfg or ctermbg are defined, use start/stop + sequences. Add remark in docs that :if 'term' == "term-name" should be + used. +8 Add @spell cluster to String and Comment groups for many languages. Will + allow spell checking. (Fleiner) +8 When listing syntax items, try to sort the keywords alphabetically. And + re-insert the [] if possible. +8 Make it possible to use color of text for Visual highlight group (like for + the Cursor). +8 "fg" and "bg" don't work in an xterm. Get default colors from xterm with + an ESC sequence. Ideas in: ~/vim/patches/vikas.xtermcolors . +8 Make it possible to only highlight a sub-expression of a match. Like + using "\1" in a ":s" command. +8 Support for deleting syntax items: + :syn keyword cTodo remove this + :syn match cTodo remove "pattern" + :syn region cString remove start="this" end="that" +8 Add possibility to sync on something else, when the syncing in one way + doesn't find match. For HTML: When no {script} is found, try looking for + a '<'. (Fleiner) +7 Replace the synchronizing method with a state machine specification? + Should be able to start at any line in the file, search forwards or + backwards, and use the result of matching a pattern. +7 Use parsing like awk, so that e.g., a ( without a matching ) can be + detected. +8 Make it possible to use "inverted" highlighting, invert the original + character. For Visual mode. (xterm-selection already does this). +8 Highlight non-printable characters with "SpecialChar", linked to + "Special". Display them with the digraph characters, if possible. +7 Add "DefaultFG" and "DefaultBG" for the colors of the menu. (Martin + Dalecki has a patch for Motif) +8 Highlight the clipboard-selection with a highlight group. +8 Be able to reset highlighting to its original (default) values. +7 Be able to write current highlighting to a file as commands, similar to + ":mkvimrc". +8 Improve c.vim: + - Add check for unterminated strings, with a variable to switch it on: + "c_strict_ansi". + - Detect unbalanced "#endif". Requires looking back a long way... +8 Add an option to restrict the updating of syntax highlighting to the + current line while in Insert mode. +8 When guessing value of 'background', the syntax file has already been + loaded (from the .gvimrc). After changing 'background', load it again? +8 Add ":syn resync" command, to re-parse the whole file until the current + display position. +8 Should support "me" offset for a region start pattern. To be used to + allow searching for the end pattern inside the match of the end pattern. + Example: syn region pikeXX start="([^{]" end=")" should work on "()". +8 When using a regexp for "contains=", should delay matching with it until + redrawing happens. Set a flag when a group is added, check this flag when + highlighting starts. +7 Add "semitrans": Add highlighting. E.g., make the text bold, but keep the + colors. And add colors, so that Green+Red becomes Yellow. + E.g. for this html: + <B> bold text <I> italic+bold text </B> italic text </I> +7 Wild idea: Not only set highlighting, but also change what is displayed + (e.g., remove characters, so that "<B>bold</B>" can be shown as "bold"): + :syn region boldstuff start="<B>" display="" end="</B>" display="" +7 CTRL-] checks the highlight group for finding out what the tag is. +7 Add an explanation how a list of words can be used to highlight misspelled + words. +8 Add spell checking. Use "ispell -a" somehow. + ~/vim/patches/wm_vim-5_4d.zip can be used as an example (includes ispell + inside Vim). Gautam Iyer has an example with "aspell". "engspchk" from + Charles Campbell is a good way. Support for approximate-regexps will help + (agrep http://www.tgries.de/agrep/). +7 Command line completion for ":find" should search in 'path'. +8 Add more command line completion for :syntax. +8 Add more command line completion for :highlight. +8 Add more command line completion for :sign. +7 Should find a better way to parse the :syntax and :highlight commands. + Use tables or lists that can be shared by parsing for execution and + completion? +8 Add ColorSchemePost autocommand event, so that scripts can set up their + highlighting. (Salman Halim) +7 Add a few sets of colors (e.g. Borland Turbo C one). With a menu to + select one of the sets. +8 Add offsets to sub-matches: "\(a*\) *"he=e1-1 + 'e' is end of match 'e1' is end of sub-match 1, 's2' is start of submatch + 2, etc. +8 In Insert mode, when there are typeahead characters, postpone the + highlighting (for "." command). +8 Syncing on comments isn't 100% correct when / / lines mix with / * and * /. + For example: What about a line that starts with / / and contains * /? +8 Ignore / * and * / inside strings, when syncing. +7 Build a few more syntax files from the file "/usr/share/misc/vgrindefs": + ISP, LDL, Icon, ratfor. And check "nedit/source/highlight.c". +6 Add possibility to have background color continue until the right edge of + the window. Useful for comment blocks and function headings. (Rogall) +- Make it possible to add "contains" items for all items in a group. Useful + when extending an already existing syntax file. +- Add line-continuation pattern for non-syncing items too? +- Add possibility to highlight specific columns (for Fortran). Or put a + line in between columns (e.g. for 'textwidth'). + Patch to add 'hlcolumn' from Vit Stradal, 2004 May 20. +- Add possibility to highlight the whole line, including the right margin + (for comment blocks). +- Add 'hlmatch' option: List of flags: + 'c': highlight match for character under the cursor. + 'b': highlight the previous (, and its match. + 'a': highlight all text from the previous ( until its match. + Also for {}, <>, etc.? + 'e': highlight all braces without a match (slow?) + OR: add an argument "cursor" to the syntax command, which means that the + region/match/keyword is only highlighted when the cursor is on it. + (Campbell) + Or do it like Elvis: define text objects and how to highlight them around + the cursor. (Iain Truskett) +7 Make it possible to use all words in the tags files as Keyword. + Can also be done with a script (but it's slow). +7 Make it possible to call a ":" command when a match is found. Should + allow for adding keywords from the text (e.g. variables that are set). + And allows for sections with different highlighting. +7 Add highlight group for commandline: "Commandline". Make sure it + highlights the command line while typing a command, and any output from + messages. And external commands? +8 Make a version that works like less, but with highlighting: read stdin for + text, exit at end of file, don't allow editing, etc. moreim? lessim? +7 SpecialKey highlighting overrules syntax highlighting. Can't give an + unprintable char another color. Would be useful for ^M at end of line. + + +Built-in script language: +8 Add referring to key options with "&t_xx". Both for "echo &t_xx" and + ":let &t_xx =". Useful for making portable mappings. +8 Allow range for ":exec". Pass it on to the executed command. (Webb) +8 exists("&&option") tests if 'option' is actually implemented. Useful for + 'shellslash', for example. +7 Be able to call a function while passing on a variable number of + arguments: + :function Foo(abc, ...) + : call Bar(a:abc, a:*) + Charles Campbell has a patch for this +8 Have a look at VSEL. Would it be useful to include? (Bigham) +8 Add ":fungroup" command, to group function definitions together. When + encountered, all functions in the group are removed. Suggest using an + obscure name to avoid name clashes. Require a ":fungroup END" in the same + sourced file? Assume the group ends at the end of the file. Handle + nested packages? + Alternative: Support packages. {package-name}:{function-name}(). + Packages are loaded automatically when first used, from + $VIMRUNTIME/packages (or use a search path). +7 Make globpath() also work with "**" and upwards search. (Brian Medley) +7 Pre-parse or compile Vim scripts into a bytecode. + 1. Put the bytecode with the original script, with an ":if + has('bytecode')" around it, so that it's only used with a Vim that + supports it. Update the code with a command, can be used in an + autocommand. + 2. Use a ".vic" file (like Python use .pyc). Create it when writing a + .vim file. Problem: distribution. + 3. Use a cache directory for each user. How to recognize which cached + file belongs to a sourced script? +7 Add "n" flag to search() function, just like searchpair(). (Alexey + Marinichev) +8 Add ":n" to fnamemodify(): normalize path, remove "../" when possible. + Aric Blumer has a patch for this. +7 Add argument to winwidth() to subtract the space taken by 'foldcolumn', + signs and/or 'number'. +8 Add functions: + multibyteidx(string, idx) Byte index in multi-byte character. + Patch by Ilya Sher, 2004 Feb 25 + menuprop({name}, {idx}, {what}) + Get menu property of menu {name} item {idx}. + menuprop("", 1, "name") returns "File". + menuprop("File", 1, "n") returns "nmenu + File.Open..." argument. + Patch by Ilya Sher, 2004 Apr 22 + mapname({idx}, mode) return the name of the idx'th mapping. + Patch by Ilya Sher, 2004 Mar 4. + match({pat}, {string} [,start] [,count]) get index of count'th match + Patch by Ilya Sher, 2004 Mar 31 + sprintf(format, arg, ..)

Store byte codes in a vim script file + at the end, after "compiled:. Make it look like a single comment line + for old Vim versions. Insert first line "Vim script compiled <timestamp>. + Only used compiled code when timestamp matches the file stat. + Add command to compile a vim script and add it to the file in-place. + Split Ex command executing into a parsing and executing phase. + Use compiled code for functions, while loops, etc. +8 When editing a file with extremely long lines (e.g., an executable), the + "linerest" in readfile() is allocated twice to be able to copy what was + read so far.

Then read the next block into another + fixed-size buffer, create the second list of indexes and copy text from + the two blocks to the memfile block. +7 do_cmdline(): Avoid that the command line is copied to allocated memory + and freed again later all the time. For while loops, and for when called + with an argument that can be messed with. + Generic solution: Make a struct that contains a pointer and a flag that + indicates if the pointer should be freed when replaced. +7 Check that the file size is not more than "sizeof(long)". +- Further improve finding mappings in maphash[] in vgetorpeek() +8 Syntax highlighting is slow when deleting lines. Try in + $VIMRUNTIME/filetype.vim. +- "out of memory" after deleting (1,$d) and changing (:%s/^/> /) a lot of + lines (27000) a few times. Memory fragmentation? +- Have a look at how pdksh does memory allocation (alloc.c). (Dalecki) +- Do profiling on: + - :g/pat/normal cmd + - 1000ii<Esc> + - deleting 10Mbyte worth of lines (netscape binary) + - "[i" and "[d" (Yegappan Lakshmanan) + - ":g/^/m0" on a 450Kbyte file. And the "u". + - highlighting "~/vim/test/longline.tex", "~/vim/test/scwoop.tcl" and + "~/vim/test/lockup.pl". + - loading a syntax file to highlight all words not from a dictionary. + - editing a vim script with syntax highlighting on (loading vim.vim). +7 Screen updating can be further improved by only redrawing lines that were + changed (and lines after them, when syntax highlighting was used, and it + changed). + - On each change, remember start and end of the change. + - When inserting/deleting lines, remember begin, end, and line count. +- Use macros/duarte/capicua for profiling. Nvi 1.71 is the fastest! +- When using a file with one long line (1Mbyte), then do "$hhhh", is still + very slow. Avoid calling getvcol() for each "h"? +- Executing a register, e.g. "10000@@" is slow, because ins_typebuf has to + move the previous commands forward each time. Pass count from + normal_cmd() down to do_execreg(). +- Repeating insert "1000i-<Esc>" displays --INSERT-- all the time, because of + the <Esc> at the end.

Be a bit more + specific: Negative, beyond last line, reverse range? Include the text. +8 Make it possible to ignore errors for a moment ('errorignore'?). Another + option to switch off giving error messages ('errorquiet'?). Also an option + not to give any messages ('quiet')? Or ":quiet on", ":quiet off". + Careful: For a severe error (out of memory), and when the user starts + typing, error messages must be switched back on. + Also a flag to ignore error messages for shell commands (for mappings). +- Option to set time for emsg() sleep. Interrupt sleep when key is typed? + sleep before second message? +8 In Ex silent mode or when reading commands from a file, what exactly is + not printed and what is? Check ":print", ":set all", ":args", ":vers", + etc. At least there should be no prompt. (Smulders) And don't clear the + screen when reading commands from stdin. (Kendall) + --> Make a difference between informative messages, prompts, etc. and + error messages, printing text, etc. +8 Window should be redrawn when resizing at the hit-enter prompt. + Also at the ":tselect" prompt. Find a generic solution for redrawing when + a prompt is present (with a callback function?). + + +Screen updating: +7 Add a string to the 'display' option to make CTRL-E and CTRL-Y scroll one + screen line, also if this means the first line doesn't start with the + first character (like what happens with a single line that doesn't fit). +- screen_line(): + - insert/delete character stuff. + - improve delete rest of line (spaces at end of line). +- When moving or resizing window, try to avoid a complete redraw (esp. when + dragging the status line with the mouse). +- When 'lazyredraw' set, don't echo :ex commands? Need a flag to redraw when + waiting for a character. +8 Add a ":refresh [winnr]" command, to force updating a window. Useful from + an event handler where ":normal" can't be used. Also useful when + 'lazyredraw' is set in a mapping. +7 Make 'list' and 'linebreak' work together. +7 Add "nbsp" in 'listchars'? Patch from David Blanchet, 2003 Jul 28. + + +Scrolling: +8 Add "zm" command: scroll horizontally to put the cursor in the middle. +6 Add option to set the overlap for CTRL-F and CTRL-B. (Garhi) +- extend 'scrollbind' option: 'scrollopt' words "search", "relative", etc.. + Also 'e'xecute some commands (search, vertical movements) in all bound + windows. +7 Add 'scrollbind' feature to make the offset of one window with the next + one equal to the window height. When editing one file in both windows it + looks like each window displays a page of the buffer. +- Allow scrolling by dragging with the mouse (grab a character and move it + up/down). Like the "hand" in Acrobat reader. Use Alt-LeftMouse for this? + (Goldfarb) +- Add command to execute some commands (search, vertical movements) in all + bound windows. +- Add 'search' option to 'scrollopt' to allow 'scrollbind' windows to + be bound by regexp searches +- Add "z>" and "z<": scroll sideways one screenfull. (Campbell) +- Add option to set the number of lines when not to scroll, instead of the + fixed number used now (for terminals that scroll slow with a large number + of lines but not with a single line). + + +Autoconf: +8 Should use acconfig.h to define prototypes that are used by autoheader. +8 Some compilers don't give an error for "-OPT:Olimit" but a warning. (Webb) + Add a check for the warning, so that "Olimit" can be added automatically? +- Autoconf: Use @datadir@ for the system independent files. Make sure the + system dependent and system independent files are separated. (Leitner). +- Add autoconf check for waitpid()/wait4(). +- Remove fcntl() from autoconf, all systems have it? +- Set default for 'dictionary', add search for dictionary to autoconf. + + +Perl interface: +8 Rename typemap file to something else? +7 Add patch from Benoit Cerrina to integrate Vim and Perl functions better. + Now also works for Ruby (2001 Nov 10) +7 Make buffers accessed as Perl arrays. (Clark) +7 Make it possible to compile with non-ANSI C? +6 Tcl/Tk has the "load" command: load a shared library (.so or .dll). + + +Shared libraries: +6 Add support for loading shared libraries, and calling functions in it. + :libload internal-name libname + :libunload internal-name + :liblist + :libcall internal-name function(arg1, arg2, ...) + :libcall function(arg1, arg2, ...) + libcall() can have only one integer or String argument at the moment. +6 Have a look on how Perl handles loading dynamic libraries. + + +Tags: +8 Add a command to jump to a certain kind of tag. Allow the user to specify + values for the optional fields. E.g., ":tag size type=m". +8 Add a function that returns the line in the tags file for a matching tag. + Can be used to extract more info (class name, inheritance, etc.) (Rico + Hendriks) +7 Count before CTRL-]: jump to N'th match +8 Scope arguments for ":tag", e.g.: ":tag class:cPage open", like Elvis. +8 When output of ":tselect" is long, getting the more-prompt, should be able + to type the tag number directly. +7 Add a tag-select window. Works like ":cwindow". (Michal Malecki) +7 Add the possibility to use the "-t {tag}" argument multiple times. Open a + window for each tag. +7 Make output of ":tselect" a bit nicer. Use highlighting? +7 Highlight the "tag 1 of >2" message. New highlight group, or same as "hit + bottom" search message. +7 When using ":tag" at the top of the tag stack, should add another entry, + so CTRL-T can bring you back to where you are now AND to where you were + before the previous ":tag" command. (Webb) +7 When using CTRL-] on someClass::someMethod, separate class from method and + use ":ta class:someClass someMethod". + Include C++ tags changes (Bertin). Change "class::func" tag into "func" + with "class=class"? Docs in oldmail/bertin/in.xxx. +7 Add ":tagargs", to set values for fields: + :tagargs class:someclass file:version.c + :tagargs clear + These are then the default values (changes the order of priority in tag + matching). +7 Support for "gtags" and "global"? With ":rtag" command? + There is an example for how to do this in Nvi. + Or do it like Elvis: 'tagprg' and 'tagprgonce' options. (Yamaguchi) + The Elvis method is far more flexible, do it that way. +7 Support "col:99" extra field, to position the cursor in that column. With + a flag in 'cpoptions' to switch it off again. +7 Better support for jumping to where a function or variable is used. Use + the id-utils, with a connection to "gid" (Emacs can do it too). Add + ":idselect", which uses an "ID" database (made by "mkid") like "tselect". +7 Add 'taglistfiles' option, show file name and type when listing matching + tags name with CTRL-D completion. Patch from Yegappan Lakshmanan. + + +Security: +- nothing at the moment + + +Win32 GUI: +8 Make debug mode work while starting up (vim -D). Open console window for + the message and input? +7 The Python interface only works with one version of Python, selected at + compile time. Can this be made to work with version 2.1 and 2.2 + dynamically? +7 GvimExt: when there are several existing Vims, move the list to a submenu. + (Mike McCollister) +8 When using "Edit with Vim" for one file it changes directory, when several + files are selected and using "Edit with single Vim" the directory isn't + changed. At least change directory when the path is the same for all + files. Perhaps just use the path of the first file or use the longest + common part of the path. +8 Add font argument to set the lfCharSet. (Bobcik) +8 Somehow automatically detect the system language and set $LANG, so that + gettext and menus work. +8 Could keep console open to run multiple commands, to avoid the need to hit + return in every console. + Also: Look at how Emacs does runs external commands: + http://www.cs.washington.edu/homes/voelker/ntemacs.html. +8 Need a separate PopUp menu for modeless selection. Need two new commands: + Copy selection to clipboard, Paste selection (as typed text). +8 Support copy/paste for other file formats. At least HTML, perhaps RTF. + Add "copy special" and "paste special" commands? +7 Use different default colors, to match the current Windows color scheme. + Sys_WindowText, Sys_Window, etc. (Lionel Schaffhauser) +7 Use <C-Tab> to cycle through open windows (e.g., the find dialog). +7 <Esc> should close a dialog. +7 Keep the console for external commands open. Don't wait for a key to be + hit. Re-open it when the user has closed it anyway. Or use a prepended + command: ":nowait {cmd}", or ":quiet", which executes {cmd} without any + prompts. +7 Should be able to set an option so that when you double click a file that + is associated with Vim, you can either get a new instance of Vim, or have + the file added into an already running Vim. +7 The "-P" argument only works for the current codepage. Use wide + functions to find the window title. + + +GUI: +8 Add GTK 2.3 file dialog support. Patch by Grahame Bowland, 2004 Mar 15, + but it doesn't use "initdir" or "dflt". +8 Make inputdialog() work for Photon, Amiga, RiscOS. +- <C--> cannot be mapped. Should be possible to recognize this as a + normal "-" with the Ctrl modifier. +7 Implement ":popup" for other systems than Windows. +8 Implement ":tearoff" for other systems than Win32 GUI. +6 Implement ":untearoff": hide a torn-off menu. +8 When using the scrollbar to scroll, don't move the cursor position. When + moving the cursor: scroll to the cursor position. +9 Make <S-Insert> paste from the clipboard by default. (Kunze) +7 Menu local to a buffer, like mappings. Or local to a filetype? +8 In Buffers menu, add a choice whether selecting a buffer opens it in the + current window, splits the window or uses ":hide". +8 Dragging the mouse pointer outside of a Vim Window should make the text + scroll. Return a value from gui_send_mouse_event() to the machine + specific code to indicate the time in which the event should be repeated. +8 Make it possible to ignore a mouse click when it's used to give Vim (gvim) + window focus. Also when a mouse click is used to bring a window to front. +8 Make the split into system independent code and system specific code more + explicit. There are too many #ifdefs in gui.c. + If possible, separate the Vim code completely from the GUI code, to allow + running them in separate processes. +8 Support a background bitmap. Useful for marking a column. Patch from + Heather Downs (GTK) and Vince Negri (Win32). +7 X11: Support cursorColor resource and "-cr" argument. +8 X11 (and others): CTRL-; is not different from ';'. Set the modifier mask + to include CTRL for keys where CTRL produces the same ASCII code. +7 Add some code to handle proportional fonts? Need to draw each character + separately (like xterm). Also for when a double-width font is not exactly + double-width. (Maeda) +8 Should take font from xterm where gvim was started (if no other default). +8 Selecting font names in X11 is difficult, make a script or something to + select one. Martin Dalecki has a font selector for Motif, but it needs a + bit more work. +7 Motif: use the menu font consistently. Patch from Martin Dalecki 2002 Jan + 11. +8 Visual highlighting should keep the same font (bold, italic, etc.). +8 Add flag to 'guioptions' to not put anything in the clipboard at all? +8 Should support a way to use keys that we don't recognize yet. Add a + command that adds entries to special_keys somehow. How do we make this + portable (X11, Win32, ..)? +7 Add a flag to 'guioptions' that tells not to remove inactive menu items. + For systems where greying-out or removing menu items is very slow. The + menu items would remain visibly normally, but not do anything. +7 Add ":minimize" and ":maximize", which iconize the window and back. + Useful when using gvim to run a script (e.g. 2html.vim). +7 X11: Is it possible to free allocated colors, so that other programs can + use them again? Otherwise, allow disabling allocating the default colors. + Or allocate an own colormap (check UAE). With an option to use it. For + the commandline, "-install" is mostly used for X11 programs. +7 Add command line argument for "gvim" not to start the GUI. Sort of the + inverse of "vim -g". (Vikas) +7 Should support multi-column menus. +- Should add option for where to put the "Help" menu: like Motif at the far + right, or with the other menus (but still at the right). +- Add menu item to "Keep Insert mode". +8 ":mkgvimrc" command, that includes menus. +6 Big change: Move GUI to separate program "vimgui", to make startup of vim a + lot faster, but still be able to do "vim -g" or ":gui". +7 More explicit mouse button binding instead of 'mousemodel'? +7 Add option to set the position of the window on the screen. 'windowpos', + which has a value of "123,456": <x>,<y>. + Or add a command, like ":winsize"? +7 Add toolbar for more GUIs. +8 Make it possible to use "amenu icon=BuiltIn##", so that the toolbar item + name can be chosen free. +7 Make it possible to put the toolbar on top, left, right and/or bottom of + the window? Allows for softkey-like use. +6 Separate the part of Vim that does the editing from the part that runs the + GUI. Communicate through a pseudo-tty. Vim starts up, creates a + pty that is connected to the terminal. When the GUI starts, the pty is + reconnected to the GUI process. When the GUI stops, it is connected to + the terminal again. Also use the pty for external processes, it looks + like a vt100 terminal to them. Vim uses extra commands to communicate GUI + things. +7 Motif: For a confirm() dialog <Enter> should be ignored when no default + button selected, <Esc> should close the dialog. +- Motif steals <F10> from us, to pop up menus with the keyboard. How do we + get it back if we want it? +- Motif: add 3D shading for the menu entries? Patch from Martin Dalecki. +- Paste in Insert mode should not do autowrap etc. Or maybe this should be + changeable with an option? +- Put a nice picture in the icon (but how do we do that?). +7 When using a pseudo-tty Vim should behave like some terminal (vt52 looks + simple enough). Terminal codes to/from shell should be translated. +- Would it be useful to be able to quit the GUI and go back to the terminal + where it was started from? +7 Support "-visual <type>" command line argument. + + +VMS: +- Improvement: rewrite term/TTY handling. +- Improvement: create VMS GTK runtime libraries on OpenVMS 7.1-2 (today GTK + works just on 7.3). + + +Autocommands: +9 Make sure that side effects of autocommands are handled correctly. Don't + execute autocommands when a buffer or window is halfway some changes. + Move all apply_autocmds() calls to a higher level where needed. +8 Add ScriptReadCmd event: used to load remote Vim scripts, e.g. + "vim -u http://mach/path/vimrc". +8 Use another option than 'updatetime' for the CursorHold event. The two + things are unrelated for the user (but the implementation is more + difficult). +8 Also trigger CursorHold in Insert mode? +7 Add autocommand event for when a buffer cannot be abandoned. So that user + can define the action taking (autowrite, dialog, fail) based on the kind + of file. (Yakov Lerner) Or is BufLeave sufficient? +8 Can't use ":normal" in CursorHold autocommands. Make the CursorHold event + insert a special key code, and call the autocommand functions from a + higher level, so that vgetc() isn't used recursively. +8 Autocommands should not change registers. And marks? And the jumplist? + And anything else? +8 Autocommand for when modified files have been found, when getting input + focus again (e.g., FileChangedFocus). + Check when: getting focus, jumping to another buffer, ... +8 Add autocommands, user functions and user commands to ":mkvimrc". +8 Add "TagJumpFile" autocommand: When jumping to another file for a tag. + Can be used to open "main.c.gz" when "main.c" isn't found. +6 Add KeymapChanged event, so that the effects of a different keymap can be + handled (e.g., other font) (Ron Aaron) +7 Add a way to skip an autocommand if going from one *.c file to another *.c + file. +7 When trying to open a directory, don't load the file but trigger an + autocommand event OpenDirectory. +7 Add file type in front of file pattern: <d> for directory, <l> for link, + <x> for executable, etc. <&xxx> for Risc OS. With commas to separate + alternatives. The autocommand is only executed when both the file type + AND the file pattern match. (Leonard) +5 Add option that specifies extensions which are to be discarded from the + file name. E.g. 'ausuffix', with ".gz,.orig". Such that file.c.gz will + trigger the "*.c" autocommands. (Belabas) +7 Add something to break the autocommands for the current event, and for + what follows. Useful for a "BufWritePre" that wants to avoid writing the + file. +8 When editing "tt.gz", which is in DOS format, 'fileformat' stays at + "unix", thus writing the file changes it. Somehow detect that the read + command used dos fileformat. Same for 'fileencoding'. +8 Add buffer-local autocommands? Reduces overhead for autocommands that + trigger often (inserting a character, switching mode). + :au Event <buffer> do-something + E.g.: + :au BufEnter <buffer> menu enable ... + :au BufLeave <buffer> menu disable ... + Patch from Yakov Lerner, including test (2004 Jan 7). +- Add events to autocommands: + Error - When an error happens + NormalEnter - Entering Normal mode + InsertEnter - Entering Insert mode + ReplaceEnter - Entering Replace mode + CmdEnter - Entering Cmdline mode + VisualEnter - Entering Visual mode + CmdUndefined - Like FuncUndefined but for user commands. + *Leave - Leaving the mode + SearchPost - After doing a search command (e.g. to do "M") + PreDirChanged/PostDirChanged + - Before/after ":cd" has been used (for changing the + window title) + BufReadAction - replaces reading a file + BufWriteAction - replaces writing a file + ShutDown - when the system is about to shut down + InsertCharPre - user typed character Insert mode, before inserting the + char. Pattern is matched with text before the cursor. + Set v:char to the character, can be changed. + (not triggered when 'paste' is set). + InsertCharPost - user typed a character in Insert mode, after inserting + the char. + BufModified - When a buffer becomes modified, or unmodified (for + putting a [+] in the window title or checking out the + file from CVS). + BufFirstChange - When making a change, when 'modified' is set. Can be + used to do a :preserve for remote files. + BufChange - after a change was made. Set some variables to indicate + the position and number of inserted/deleted lines, so + that marks can be updated. HierAssist has patch to add + BufChangePre, BufChangePost and RevertBuf. (Shah) + WinResized - When a window has been resized + VimResized - When the Vim window has been resized (SIGWINCH) + patch from Yakov Lerner, 2003 July 24. +- Add autocommand to be executed every so many seconds? For writing the + file now and then ('autosave'). + *'autosave'* *'as'* *'noautosave'* *'noas'* + 'autosave' 'aw' number (default 0) + Automatically write the current buffer to file N seconds after the + last change has been made and when |'modified'| is still set. + Default: 0 = do not autosave the buffer. + Alternative: have 'autosave' use 'updatetime' and 'updatecount' but make + them save the file itself besides the swapfile. + + +Insert mode completion/expansion: +8 When there is no word before the cursor but something like "sys." complete + with "sys.". Works well for C and similar languages. +9 ^X^L completion doesn't repeat correctly. It uses the first match with + the last added line, instead of continuing where the last match ended. + (Webb) +8 The code has become too complex. Redesign it, or at least add proper + comments. +8 Add option to set different behavior for Insert mode completion: + - ignore/match case + - different characters than 'iskeyword' +8 Add expression-expansion, so that the user can define his own kind of + completion. Patch from Taro Muraoka, 2003 Aug 26. +8 Add a command to undo the completion, go back to the original text. +8 Use the class information in the tags file to do context-sensitive + completion. After "foo." complete all member functions/variables of + "foo". Need to search backwards for the class definition of foo. + Should work for C++ and Java. + Even more context would be nice: "import java.^N" -> "io", "lang", etc. +7 When expanding $HOME/dir with ^X^F keep the $HOME (with an option?). +7 Add CTRL-X command in Insert mode like CTRL-X CTRL-N, that completes WORDS + instead of words. +8 Add CTRL-X CTRL-R: complete words from register contents. +8 Add completion of previously inserted texts (like what CTRL-A does). + Requires remembering a number of insertions. +8 Add 'f' flag to 'complete': Expand file names. + Also apply 'complete' to whole line completion. +- Make it possible to search include files in several places. Use the + 'path' option? Can this be done with the dictionary completion (use + wildcards in the file name)? +- Make CTRL-X CTRL-K do a binary search in the dictionary (if it's sorted). +- Speed up CTRL-X CTRL-K dictionary searching (don't use a regexp?). +- Set a mark at the position where the match was found (file mark, could + be in another file). +- Add CTRL-A command in CTRL-X mode: show all matches. +- Make CTRL-X CTRL-L use the 'complete' option? +- Add command in CTRL-X mode to add following words to the completed string + (e.g. to complete "Pointer->element" with CTRL-X CTRL-P CTRL-W CTRL-W) +- CTRL-X CTRL-F: Use 'path' to find completions. +- CTRL-X CTRL-F: Option to use forward slashes on MS-Windows? +- CTRL-X CTRL-F: Don't replace "$VIM" with the actual value. (Kelly) +8 Add option 'isexpand', containing characters when doing expansion (so that + "." and "\" can be included, without changing 'iskeyword'). (Goldfarb) + Also: 'istagword': characters used for CTRL-]. + When 'isexpand' or 'istagword' are empty, use 'iskeyword'. +- Allow listing all matches in some way (and picking one from the list). + + +Command line editing: +7 Add commands (keys) to delete from the cursor to the end of the command + line. +8 Custom completion of user commands can't use the standard completion + functions. Add a hook to invoke a user function that returns the type of + completion to be done: "file", "tag", "custom", etc. +- Add flags to 'whichwrap' for command line editing (cursor right at end of + lines wraps to start of line). +- Make editing the command line work like Insert mode in a single-line view + on a buffer that contains the command line history. But this has many + disadvantages, only implement it when these can be solved. Elvis has run + into these, see remarks from Steve (~/Mail/oldmail/kirkendall/in.00012). + - Going back in history and editing a line there would change the history. + Would still need to keep a copy of the history elsewhere. Like the + cmdwin does now already. + - Use CTRL-O to execute one Normal mode command. How to switch to normal + mode for more commands? <Esc> should cancel the command line. CTRL-T? + - To allow "/" and "= need to recursively call getcmdline(), overwrite the + cmdline. But then we are editing a command-line again. How to avoid + that the user gets confused by the stack of command lines? + - Use edit() for normal cmdline editing? Would have to integrate + getcmdline() into edit(). Need to solve conflicts between Insert mode + and Command-line mode commands. Make it work like Korn shell and tcsh. + Problems: + - Insert: completion with 'wildchar' + - Insert: use cmdline abbreviations + - Insert: CTRL-D deletes indent instead of listing matches + - Normal: no CTRL-W commands + - Normal: no ":" commands? + - Normal: allow Visual mode only within one line. + - where to show insert/normal mode message? Change highlighting of + character in first column? + - Implementation ideas: + - Set "curwin" and "curbuf" to the command line window and buffer. + - curwin->w_topline is always equal to curwin->w_cursor.lnum. + - never set 'number', no folding, etc. No status line. + - sync undo after entering a command line? + - use NV_NOCL flag for commands that are not allowed in Command-line + Mode. + + +Command line completion: +8 Change expand_interactively into a flag that is passed as an argument. +8 With command line completion after '%' and '#', expand current/alternate + file name, so it can be edited. Also with modifiers, such as "%:h". +8 When completing command names, either sort them on the long name, or list + them with the optional part inside []. +7 Completion of network shares, patch by Yasuhiro Matsumoto. +7 Completion of ":map x ": fill in the current mapping, so that it can be + edited. (Sven Guckes) +7 Add completion for when entering an expression after CTRL-R= and "=. + (Servatius Brandt) +- For 'wildmenu': Simplify "../bar" when possible. +- When using <Up> in wildmenu mode for a submenu, should go back to the + current menu, not the first one. E.g., ":emenu File.Save<Up>". +8 For ":find" and ":sfind" expand files found in 'path'. +8 Add cmdline completion for the ":debug" command. +8 When using backtick expansion, the external command may write a greeting + message. Add an option or commands to remove lines that match a regexp? +7 When listing matches of files, display the common path separately from the + file names, if this makes the listing shorter. (Webb) +- Add command line completion for ":ilist" and friends, show matching + identifiers (Webb). +8 Add command line completion for "old value" of a command. ":args <key>" + would result in the current list of arguments, which you can then edit. +7 Add command line completion with CTRL-X, just like Insert mode completion. + Useful for ":s/word/xx/". +- Add command to go back to the text as it was before completion started. + Also to be used for <Up> in the command line. +- Add 'wildlongest' option: Key to use to find longest common match for + command line completion (default CTRL-L), like 'wildchar'. (Cregut) + Also: when there are several matches, show them line a CTRL-D. +- Add completion for Environment variables: ":echo $SH<Tab>" -> "$SHELL". + + +Command line history: +- Add "KeyWasTyped" flag: It's reset before each command and set when a + character from the keyboard is consumed. Value is used to decide to put a + command line in history or not. Put line in history if it didn't + completely resulted from one mapping. +- When using ":browse", also put the resulting edit command in the history, + so that it can be repeated. (Demirel) + + +Insert mode: +9 When 'autoindent' is set, hitting <CR> twice, while there is text after + the cursor, doesn't delete the autoindent in the resulting blank line. + (Rich Wales) This is Vi compatible, but it looks like a bug.

(Eggink) + Perhaps it can be allowed a single time, to be able to do + "<C-O>10axyz<Esc>". Nesting this further is confusing. + ":map <F2> 5aabc<Esc>" works only once from Insert mode. +7 Use CTRL-G <count> to repeat what follows. Useful for inserting a + character multiple times or repeating CTRL-Y. +7 Make ":startinsert" command work directly for functions and scripts? + Also make it possible to append (it's difficult at end of line). + And add ":startreplace" (patch by Charles Campbell, 2004 Jan 9, + http://www.erols.com/astronaut/vim/index.html#Patch) +7 Use 'matchpairs' for 'showmatch': When inserting a character check if it + appears in the rhs of 'matchpairs'. +- In Insert mode (and command line editing?): Allow undo of the last typed + character. This is useful for CTRL-U, CTRL-W, delete and backspace, and + also for characters that wrap to the next line. + Also: be able to undo CTRL-R (insert register). + Possibly use 'backspace'="whole" for a mode where at least a <CR> that + inserts autoindent is undone by a single <BS>. +- Use CTRL-G in Insert mode for an extra range of commands, like "g" in + Normal mode. +- Make 'paste' work without resetting other options, but override their + value. Avoids problems when changing files and modelines or autocommands + are used. +- When typing CTRL-V and a digit higher than 2, only expect two digits. +- Insert binary numbers with CTRL-V b. +- Make it possible to undo <BS>, <C-W> and <C-U>.

Need to continue looking for more + matches of "*" and remember all characters that could end the comment. +- For smartindent: When typing 'else' line it up with matching 'if'. +- 'smartindent': allow patterns in 'cinwords', for e.g. TeX files, where + lines start with "\item". +- Support this style of comments (with an option): (Brown) + /* here is a comment that + is just autoindented, and + nothing else */ +- Add words to 'cinwords' to reduce the indent, e.g., "end" or "fi". +7 Use Tabs for the indent of starting lines, pad with spaces for + continuation lines. Allows changing 'tabstop' without messing up the + indents. + And/or: Add option to copy indent as-is, without changing spaces to tabs. + also for 'autoindent'. 'keeptabs': when set don't change the tabs and + spaces used for indent, when the indent remains the same or increases. + + +Java: +8 Can have {} constructs inside parens. Include changes from Steve + Odendahl? +8 Recognize "import java.util.Vector" and use $CLASSPATH to find files for + "[i" commands and friends. +- For files found with 'include': handle "*" in included name, for Java. + (Jason) +- How to make a "package java.util" cause all classes in the package to be + searched? Also for "import java.util.*". (Mark Brophy) + + +'comments': +8 When formatting C comments that are after code, the "*" isn't repeated + like it's done when there is no code. And there is no automatic wrapping. + Recognize comments that come after code. Should insert the comment leader + when it's "#" or "//". +7 When using "comments=fg:--", Vim inserts three spaces for a new line. + When hitting a TAB, these spaces could be removed. +7 The 'n'esting flag doesn't do the indenting of the last (rightmost) item. +6 Make strings in 'comments' option a RE, to be able to match more + complicated things. (Phillipps) Use a special flag to indicate that a + regexp is used. +8 Make the 'comments' option with "/* * */" lines only repeat the "*" line + when there is a "/*" before it? Or include this in 'cindent'? + + +Virtual edit: +8 Make the horizontal scrollbar work to move the text further left. +7 Add a mode where the cursor is only allowed to go one character after the + end of the line? +7 Allow specifying it separately for Tabs and beyond end-of-line? + + +Text objects: +8 Add test script for text object commands "aw", "iW", etc. +7 Add text object for current search pattern: "a/" and "i/". Makes it + possible to turn text highlighted for 'hlsearch' into a Visual area. +8 Add "gp" and "gP" commands: insert text and make sure there is a single + space before it, unless at the start of the line, and after it, unless at + the end of the line or before a ".". +7 Add objects with backwards extension? Use "I" and "A". Thus "2dAs" + deletes the current and previous sentence. (Jens Paulus) +7 Add "g{" and "g}" to move to the first/last character of a paragraph + (instead of the line just before/after a paragraph as with "{" and "}"). +8 Add "a'" and 'a"': a single or double quoted string. (Tim Chase) + Patch from Taro Muraoka (2003 Dec 16). +6 Ignore comment leaders for objects. Make "das" work in reply-email. +5 Make it possible to use syntax group matches as a text object. For + example, define a "ccItem" group, then do "da<ccItem>" to delete one. + Or, maybe just define "dai", delete-an-item, to delete the syntax item the + cursor is on. + + +Select mode: +8 In blockwise mode, typed characters are inserted in front of the block, + backspace deletes a column before the block. (Steve Hall) +7 Alt-leftmouse starts block mode selection in MS Word. + See http://www.vim.org/tips/tip.php?tip_id=743 +7 Add Cmdline-select mode. Like Select mode, but used on the command line. + - Change gui_send_mouse_event() to pass on mouse events when 'mouse' + contains 'C' or 'A'. + - Catch mouse events in ex_getln.c. Also shift-cursor, etc., like in + normal_cmd(). + - remember start and end of selection in cmdline_info. + - Typing text replaces the selection. + + +Visual mode: +- When dragging the Visual selection with the mouse and 'scrolloff' is zero, + behave like 'scrolloff' is one, so that the text scrolls when the pointer + is in the top line. +8 When using "I" or "A" in Visual block mode, short lines do not get the new + text. make it possible to add the text to short lines too, with padding + where needed. +7 With a Visual block selected, "2x" deletes a block of double the width, + "3y" yanks a block of triple width, etc. +7 When selecting linewise, using "itext" should insert "text" at the start + of each selected line. +8 What is "R" supposed to do in Visual mode? +8 Make Visual mode local to the buffer. Allow changing to another buffer. + When starting a new Visual selection, remove the Visual selection in any + other buffer. (Ron Aaron) +8 Support dragging the Visual area to drop it somewhere else. (Ron Aaron, + Ben Godfrey) +7 Support dragging the Visual area to drop it in another program, and + receive dropped text from another program. (Ben Godfrey) +7 With blockwise Visual mode and "c", "C", "I", "A", etc., allow the use of + a <CR>. The entered lines are repeated over the Visual area. +7 CTRL-V :s should substitute only in the block, not to whole lines. (David + Young is working on this) +7 Filtering a block should only apply to the block, not to the whole lines. + When the number of lines is increased, add lines. When decreased, padd with + spaces or delete? Use ":`<,`>" on the command line. +8 After filtering the Visual area, make "gv" select the filtered text? + Currently "gv" only selects a single line, not useful. +7 Don't move the cursor when scrolling? Needed when the selection should + stay the same. Scroll to the cursor at any movement command. With an + option! +7 In Visual block mode, need to be able to define a corner on a position + that doesn't have text? Also: when using the mouse, be able to select + part of a TAB. Even more: Add a mode where the cursor can be on a screen + position where there is no text. When typing, add spaces to fill the gap. + Other solution: Always use curswant, so that you can move the cursor to + the right column, and then use up/down movements to select the line, + without changing the column. +6 ":left" and ":right" should work in Visual block mode. +7 For Visual mode: Command to do a search for the string in the marked area. + Only when fewer than two lines. Use "g/" and "gb". Patch from Yegappan + Lakshmanan. +7 CTRL-I and CTRL-O should work in Visual mode, but only jump to marks in the + current buffer. +7 CTRL-A and CTRL-X should increase/decrease all numbers in the Visual area. +6 In non-Block mode, "I" should insert the same text in front of each line, + before the first non-blank, "gI" in column 1. +6 In non-Block mode, "A" should append the same text after each line. +6 ":'<,'>source" should read the selected lines and ":source" them. +6 When in blockwise visual selection (CTRL-V), allow cursor to be placed + right of the line. Could also allow cursor to be placed anywhere on a TAB + or other special character. +6 Add commands to move selected text, without deselecting. + + +More advanced repeating commands: +- Add "." command for visual mode: redo last visual command (e.g. ":fmt"). +7 Repeating "d:{cmd}" with "." doesn't work. (Benji Fisher) Somehow remember + the command line so that it can be repeated? +- Add "." command after operator: repeat last command of same operator. E.g. + "c." will repeat last change, also when "x" used since then (Webb). + "y." will repeat last yank. + "c2." will repeat the last but one change? + Also: keep history of Normal mode commands, add command to list the history + and/or pick an older command. +- History stack for . command? Use "g." command. + + +Mappings and Abbreviations: +8 Let ":verbose map xx" report where the mapping was set, just like with + ":verbose set". +8 When "0" is mapped (it is a movement command) this mapping should not be + used after typing another number, e.g. "20l". (Charles Campbell) + Is this possible without disabling the mapping of the following command? +8 Should mapping <C-A> and <C-S-A> both work? +7 ":abbr b byte", append "b " to an existing word still expands to "byte". + This is Vi compatible, but can we avoid it anyway? +8 ":verbose map" could show the script where the mapping was defined. + m_script_ID can be used. +8 To make a mapping work with a prepended "x to select a register, store the + last _typed_ register name and access it with "&. +8 Add ":amap", like ":amenu". +8 Add ":cab!", abbreviations that only apply to Command-line mode and not to + entering search strings. +8 Add a flag to ":abbrev" to eat the character that triggers the + abbreviation. Thus "abb ab xxx" and typing "ab<Space>" inserts "xxx" and + not the <Space>. +8 Allow mapping of CTRL-@ (anywhere in the LHS). +8 Give a warning when using CTRL-C in the lhs of a mapping. It will never + (?) work. +7 ":verbose map" should display where a mapping was defined, like ":verbose + set". +8 Add a way to save a current mapping and restore it later. Use a function + that returns the mapping command to restore it: mapcmd()? mapcheck() is + not fool proof. How to handle ambiguous mappings? +7 Add <0x8f> (hex), <033> (octal) and <123> (decimal) to <> notation? +7 Allow mapping "Q" and "Q}" at the same time. Need to put a flag with "Q", + that it needs an extra character before it can match. See Vile 'maplonger' + option. +7 When someone tries to unmap with a trailing space, and it fails, try + unmapping without the trailing space. Helps for ":unmap xx | unmap yy". +7 Make it possible to map 'wildchar', but only when it's a special character + (like CTRL-E). Currently it's only recognized when typed. Useful for + mapping a key to do something and then completion. +7 Add a mapping that works always, for remapping the keyboard. +6 Context-sensitive abbreviations: Specify syntax group(s) in which the + abbreviations are to be used. +- Add mappings that take arguments. Could work like the ":s" command. For + example, for a mouse escape sequence: + :mapexp <Esc>{\([0-9]*\),\([0-9]*\); H\1j\2l +- Make it possible to include a <Nul> in the lhs and rhs of a mapping. +- Add command to repeat a whole mapping ("." only repeats the last change in + a mapping). Also: Repeat a whole insert command, including any mappings + that it included. Sort-of automatic recording? +- Make it possible to undo all the commands from a mapping, including a + trailing unfinished command, e.g. for ":map K iX^[r". +- Add an option to ":map" that makes it display the special keys in + <> notation (e.g. <CR> instead of ^M). Or just always do this? +- Include an option (or flag to 'cpoptions') that makes errors in mappings + not flush the rest of the mapping (like nvi does). +- Use context sensitiveness of completion to switch abbreviations and + mappings off for :unab and :unmap. +6 When using mappings in Insert mode, insert characters for incomplete + mappings first, then remove them again when a mapping matches. Avoids + that characters that are the start of some mapping are not shown until you + hit another character. +- Add optional <Number> argument for mappings: + :map <Number>q ^W^W<Number>G + :map <Number>q<Number>t ^W^W<Number1-1>G<Number2>l + :map q<Char> :s/<Char>/\u\0/g + Or implicit: + :map q <Register>d<Number>$ +- Add mappings for replace mode: ":rmap". How do we then enter mappings for + non-replace Insert mode? +- Add separate mappings for Visual-character/block/line mode? +6 Alias for Normal mode commands, works like :substitute? Would allow + mappings with arguments. +- Add 'mapstop' command, to stop recursive mappings. +- List mappings that have a raw escape sequence both with the name of the key + for that escape sequence (if there is one) and the sequence itself. +- List mappings: Once with special keys listed as <>, once with meta chars as + <M-a>, once with the byte values (octal?). Sort of "spell mapping" command? +- When entering mappings: Add the possibility to enter meta keys like they + are displayed, within <>: <M-a>, <~@> or <|a>. +- Allow multiple arguments to :unmap. +- Command to show keys that are not used and available for mapping + ":freekeys". +- Allow any character except white space in abbreviations lhs (Riehm). + + +Incsearch: +- Add a limit to the number of lines that are searched for 'incsearch'? +- When no match is found and the user types more, the screen is redrawn + anyway. Could skip that. Esp. if the line wraps and the text is scrolled + up every time. +- Temporarily open folds to show where the search ends up. Restore the + folds when going to another line. +- When incsearch used and hitting return, no need to search again in many + cases, saves a lot of time in big files. (Slootman wants to work on this?) + When not using special characters, can continue search from the last match + (or not at all, when there was no match). See oldmail/webb/in.872. +- With incsearch, use CTRL-N/CTRL-P to go to next/previous match, some other + key to copy matched word to search pattern (Alexander Schmid). + + +Searching: +8 Add a mechanism for recursiveness: "\(([^()]*\@@[^()]*)\)\@r". \@@ stands + for "go recursive here" and \@r marks the recursive atom. +item stack to allow matching (). One side is "push X on + the stack if previous atom matched". Other side is "match with top of + stack, pop it when it matches". Use "\@pX" and "\@m"? + Example: \((\@p).\{-}\@m\)* +7 Add an option to accept a match at the cursor position. Also for + search(). (Brett) +7 Add pattern item to use properties of Unicode characters. In Perl it's + "\p{L}" for a letter. See Regular Expression Pocket Reference. +7 When 'rightleft' is set, the search pattern should be displayed right to + left as well? See patch of Dec 26. (Nadim Shaikli) +8 Would it be possible to allow ":23,45/pat/flags" to search for "pat" in + lines 23 to 45? Or does this conflict with Ex range syntax? +8 Allow identical pairs in 'matchpairs'. Restrict the search to the current + line. +7 Allow longer pairs in 'matchpairs'. Use ~/vim/macros/matchit.vim as an + example. +8 Make it possible to define the character that "%" checks for in + #if/#endif. For nmake it's !if/!endif. +- For "%" command: set hierarchy for which things include other things that + should be ignored (like "*/" or "#endif" inside /* */). + Also: use "%" to jump from start to end of syntax region and back. + Alternative: use matchit.vim +8 "/:/e+1" gets stuck on a match at the end of the line. Do we care? +8 A pattern like "\([^a]\+\)\+" takes an awful long time. Recognize that + the recursive "\+" is meaningless and optimize for it. + This one is also very slow on "/* some comment */": "^\/\*\(.*[^/]\)*$". +7 Recognize "[a-z]", "[0-9]", etc. and replace them with the faster "\l" and + "\d". +7 Add a way to specify characters as hex, octal or <C-M> form. Could be + \%1ax, \%200o and \%<C-M>. Also \%1234u for multi-byte chars. +8 Flags that apply to the whole pattern. + This works for all places where a regexp is used. + Add "\q" to not store this pattern as the last search pattern? +8 Add an argument after ":s/pat/str/" for a range of matches. For example, + ":s/pat/str/#3-4" to replace only the third and fourth "pat" in a line. +8 Add an option not to use 'hlsearch' highlighting for ":s" and ":g" + commands. (Kahn) It would work like ":noh" is used after that command. + Also: An extra flag to do this once, and a flag to keep the existing + search pattern. +- Add \%h{group-name}; to search for a specific highlight group. + Add \%s{syntax-group}; to search for a specific syntax group. +- Support Perl regexp. Use PCRE (Perl Compatible RE) package. (Shade) + Or translate the pattern to a Vim one. + Don't switch on with an option for typed commands/mappings/functions, it's + too confusing. Use "\@@" in the pattern, to avoid incompatibilities. +7 Add POSIX regexp, like Nvi, with 'extended' option? It's like very-magic. +- Remember flags for backreferenced items, so that "*" can be used after it. + Check with "\(\S\)\1\{3}". (Hemmerling) +- Add flags to search command (also for ":s"?): + i ignore case + I use case + p use Perl regexp syntax (or POSIX?) + v use Vi regexp syntax + f forget pattern, don't keep it for "n" command + F remember pattern, keep it for "n" command + Perl uses these too: + e evaluate the right side as an expression (Perl only) + m multiple line expression (we don't need it) + o compile only once (Perl only) + s single line expression (we don't need it) + x extended regexp (we don't need it) + When used after ":g" command, backslash needed to avoid confusion with the + following command. + Add 'searchflags' for default flags (replaces 'gdefault'). +- Add command to display the last used substitute pattern and last used + pattern. (Margo) Maybe make it accessible through a register (like "/ + for search string)? +7 Use T-search algorithm, to speed up searching for strings without special + characters. See C't article, August 1997. +- Add 'fuzzycase' option, so that case doesn't matter, and '-' and '_' are + equivalent (for Unix filenames). +- Add 'v' flag to search command: enter Visual mode, with the matching text + as Visual area. (variation on idea from Bertin) +- Searching: "/this//that/" should find "that" after "this". +- Add global search commands: Instead of wrapping at the end of the buffer, + they continue in another buffer. Use flag after search pattern: + a for the next file in the argument list + f for file in the buffer list + w for file edited in a window. + e.g. "/pat/f". Then "n" and "N" work through files too. "f" flag also for + ":s/pat/foo/f"??? Then when 'autowrite' and 'hidden' are both not set, ask + before saving files: "Save modified buffer "/path/file"? (Yes/Hide/No + Save-all/hide-All/Quit) ". +- ":s/pat/foo/3": find 3rd match of "pat", like sed. (Thomas Koehler) +- Special characters in patterns: + Inside []: + \012 octal character + \0x1a hex character + \0<BS> \0<Esc>: special character +7 When searching with 'n' give message when getting back where the search + first started. Remember start of search in '/ mark. +7 Add option that scrolls screen to put cursor in middle of screen after + search always/when off-screen/never. And after a ":tag" command. Maybe + specify how many lines below the screen causes a redraw with the cursor in + the middle (default would be half a screen, zero means always). +6 Support multiple search buffers, so macros can be made without side + effects. +7 From xvim: Allow a newline in search patterns (also for :s, can delete + newline). Add BOW, EOW, NEWL, NLORANY, NLBUTANY, magic 'n' and 'r', etc. + [not in xvim:] Add option to switch on matches crossing ONE line boundary. +7 Add ":iselect", a combination of ":ilist" and ":tselect". (Aaron) + Also ":dselect". + + +Undo: +- When accidentally hitting "R" instead of Ctrl-R, further Ctrl-R is not + possible, even when typing <Esc> immediately. (Grahn) Also for "i", "a", + etc. Postpone saving for undo until something is really inserted? +8 When Inserting a lot of text, it can only be undone as a whole. Make undo + sync points at every line or word. Could recognize the start of a new + word (white space and then non-white space) and backspacing. + Can already use CTRL-G u, but that requires remapping a lot of things. +8 Make undo more memory-efficient: Compare text before and after change, + only remember the lines that really changed. +7 Add undo for a range of lines. Can change these back to a previous + version without changing the rest of the file. Stop doing this when a + change includes only some of these lines and changes the line count. Need + to store these undo actions as a separate change that can be undone. +7 Add an undo tree: When making a change, instead of clearing any future + undo (thus redo) info, make a new branch. How to navigate through the + undo tree? +- For u_save() include the column number. This can be used to set '[ and ']. + And in the future the undo can be made more efficient (Webb). +- In out-of-memory situations: Free allocated space in undo, and reduce the + number of undo levels (with confirmation). +- Instead of [+], give the number of changes since the last write: [+123]. + When undoing to before the last write, change this to a negative number: + [-99]. +- With undo with simple line delete/insert: optimize screen updating. +- When executing macro's: Save each line for undo only once. +- Store undo info in a file that survives until the next edit. Then it's + possible to undo to before the current editing session. Combined with + viminfo? +- When doing a global substitute, causing almost all lines to be changed, + undo info becomes very big. Put undo info in swap file?? + + +Buffer list: +8 Add patch from Charles Campbell to have ":0file!" remove the name of the + current buffer. (2003 June 17) +7 Command to execute a command in another buffer: ":inbuf {bufname} {cmd}". + Also for other windows: ":inwin {winnr} {cmd}". How to make sure that + this works properly for all commands, and still be able to return to the + current buffer/window? E.g.: ":inbuf xxx only". +8 Add File.{recent_files} menu entries: Recently edited files. + Ron Aaron has a plugin for this: mru.vim. +8 Unix: Check all uses of fnamecmp() and fnamencmp() if they should check + inode too. +7 Add another number for a buffer, which is visible for the user. When + creating a new buffer, use the lowest number not in use. (or the highest + number in use plus one?) +7 Offer some buffer selection from the command line? Like using ":ls" and + asking for a buffer number. (Zachmann) +- When starting to edit a file that is already in the buffer list, use the + file name argument for the new short file name. (Webb) +- Add an option to make ":bnext" and ":bprev" wrap around the end of the + buffer list. Also for ":next" and ":prev"? +7 Add argument to ":ls" which is a pattern for buffers to list. + E.g. ":ls *.c". (Thompson) +7 Add expansion of buffer names, so that "*.c" is expanded to all buffer + names. Needed for ":bdel *.c", ":bunload *.c", etc. +8 Support for <afile> where a buffer name is expected. +8 Some commands don't use line numbers, but buffer numbers. '$' + should then mean the number of the last buffer. E.g.: "4,$bdel". +7 Add an option to mostly use slashes in file names. Separately for + internal use and for when executing an external program? + + +Swap (.swp) files: +8 If writing to the swap file fails, should try to open one in another + directory from 'dir'. Useful in case the file system is full and when + there are short file name problems. +8 Also use the code to try using a short file name for the backup and swap + file for the Win32 and Dos 32 bit versions. +8 When a file is edited by root, add $LOGNAME to know who did su. +8 When the edited file is a symlink, try to put the swap file in the same + dir as the actual file. Adjust FullName(). Avoids editing the same file + twice (e.g. when using quickfix). Also try to make the name of the backup + file the same as the actual file? + Use the code for resolve()? +7 Store the options 'fileencoding', 'fileformat', etc. in the swapfile, + because they change what will be written to the file. Requires adding + another block to the swapfile. +7 When using 64 bit inode numbers, also store the top 32 bits. Add another + field for this, using part of bo_fname[], to keep it compatible. +7 When editing a file on removable media, should put swap file somewhere + else. Use something like 'r' flag in 'viminfo'. 'diravoid'? + Also: Be able to specify minimum disk space, skip directory when not + enough room. +7 Add a configure check for which directory should be used: /tmp, /var/tmp + or /var/preserve. +- Add an option to create a swap file only when making the first change to + the buffer. (Liang) Or only when the buffer is not read-only. +- Add option to set "umask" for backup files and swap files (Antwerpen). + 'backupumask' and 'swapumask'? Or 'umaskback' and 'umaskswap'? +- When editing a readonly file, don't use a swap file but read parts from the + original file. Also do this when the file is huge (>'maxmem'). We do + need to load the file once to count the number of lines? Perhaps keep a + cached list of which line is where. + + +Viminfo: +7 Can probably remove the code that checks for a writable viminfo file, + because we now do the chown() for root, and others can't overwrite someone + else's viminfo file. +8 Add argument to keep the list of buffers when Vim is started with a file + name. (Schild) +8 Keep the last used directory of the file browser (File/Open menu). +8 Remember the last used register for "@@". +8 Remember a list of last accessed files. To be used in the + "File.Open Recent" menu. Default is to remember 10 files or so. + Also remember which files have been read and written. How to display + this? +7 Also store the ". register (last inserted text). +7 Make it possible to store buffer names in viminfo file relative to some + directory, to make them portable over a network. (Aaron) +6 Store a snapshot of the currently opened windows. So that when quitting + Vim, and then starting again (without a file name argument), you see the + same files in the windows. Use ":mksession" code? +- Make marks present in .viminfo usable as file marks: Display a list of + "last visited files" and select one to jump to. + + +Modelines: +8 Before trying to execute a modeline, check that it looks like one (valid + option names). If it's very wrong, silently ignore it. + Ignore a line that starts with "Subject: ". +- When an option value is coming from a modeline, do not carry it over to + another edited file? Would need to remember the value from before the + modeline setting. +- Allow setting a variable from a modeline? Only allow using fixed strings, + no function calls, to avoid a security problem. +- Allow ":doauto BufRead x.cpp" in modelines, to execute autocommands for + .cpp files. +- Support the "abbreviate" command in modelines (Kearns). Careful for + characters after <Esc>, that is a security leak. +- Add option setting to ask user if he wants to have the modelines executed + or not. Same for .exrc in local dir. + + +Options: +8 Make ":mksession" store buffer-specific options for the specific buffer. +8 With ":mksession" always store the 'sessionoptions' option, even when + "options" isn't in it. (St-Amant) +7 Setting an option always sets "w_set_curswant", while this is only + required for a few options. Only do it for those options to avoid the + side effect. +8 When using ":mksession", also store a command to reset all options to + their default value, before setting the options that are not at their + default value. +8 Should ":mksession" restore the current directory when writing the + session, or the directory where the session file is? Probably need a word + in 'sessionoptions' to make a choice: + "curdir" (cd to current directory when session file was generated) + "sessiondir" (cd to directory of session file) + "nodir" (don't cd at all) +8 Make "old" number options that really give a number of effects into string + options that are a comma separated list. The old number values should + also be supported. +8 Add commands to save and restore an option, which also preserves the flag + that marks if the option was set. Useful to keep the effect of setting + 'compatible' after ":syntax on" has been used. +7 There is 'titleold', why is there no 'iconold'? (Chazelas) +7 Make 'scrolloff' a global-local option, so that it can be different in the + quickfix window, for example. (Gary Holloway) +7 Add plugins for formatting. Should be able to make a choice depending on + the language of a file (English/Korean/Japanese/etc.). + + +External commands: +8 When filtering text, redirect stderr so that it can't mess up the screen + and Vim doesn't need to redraw it. Also for ":r !cmd". +4 Set separate shell for ":sh", piping "range!filter", reading text "r !ls" + and writing text "w !wc". (Deutsche) Allow arguments for fast start (e.g. + -f). +4 Allow direct execution, without using a shell. +4 Run an external command in the background. But how about I/O in the GUI? + Careful: don't turn Vim into a shell! +4 Add feature to disable using a shell or external commands. + + +Multiple Windows: +7 "vim -oO file ..." use both horizontal and vertical splits. +8 Add CTRL-W T: go to the top window in the column of the current window. + And CTRL-W B: go to bottom window. +7 Use CTRL-W <Tab>, like alt-tab, to switch between buffers. Repeat <Tab> + to select another buffer (only loaded ones?), <BS> to go back, <Enter> to + select buffer, <Esc> to go back to original buffer. +7 Add a 'winfixwidth' option, similar to 'winfixheight'. +6 Add an option to resize the shell when splitting and/or closing a window. + ":vsp" would make the shell wider by as many columns as needed for the new + window. Specify a maximum size (or use the screen size). ":close" would + shrink the shell by as many columns as come available. (Demirel) +7 When starting Vim several times, instantiate a Vim server, that allows + communication between the different Vims. Feels like one Vim running with + multiple top-level windows. Esp. useful when Vim is started from an IDE + too. Requires some form of inter process communication. +- Support a connection to an external viewer. Could call the viewer + automatically after some seconds of non-activity, or with a command. + Allow some way of reporting scrolling and cursor positioning in the viewer + to Vim, so that the link between the viewed and edited text can be made. + + +Marks: +8 When cursor is first moved because of scrolling, set a mark at this + position. (Rimon Barr) Use '-. +8 Add a command to jump to a mark and make the motion inclusive. g'm and g`m? +8 The '" mark is set to the first line, even when doing ":next" a few times. + Only set the '" mark when the cursor was really moved in a file. +8 Make `` and '', which would position the new cursor position in the middle + of the window, restore the old topline (or relative position) from when + the mark was set. +7 Make a list of file marks in a separate window. For listing all buffers, + matching tags, errors, etc. Normal commands to move around. Add commands + to jump to the mark (in current window or new window). Start it with + ":browse marks"? +6 Add a menu that lists the Marks like ":marks". (Amerige) +8 Make it possible to delete marks. Charles Campbell has a patch that does + this with the markclear() function (2004 Jan 9). And the ":delmark" + command (2004 Feb 9) +7 For ":jumps", ":tags" and ":marks", for not loaded buffers, remember the + text at the mark. Highlight the column with the mark. +7 Highlight each mark in some way (With "Mark" highlight group). + Or display marks in a separate column, like 'number' does. +7 Use d"m to delete rectangular area from cursor to mark m (like Vile's \m + command). +7 Try to keep marks in the same position when: + - replacing with a line break, like in ":s/pat/^M/", move marks after the + line break column to the next line. (Acevedo) + - inserting/deleting characters in a line. +5 Include marks for start/end of the current word and section. Useful in + mappings. +6 Add "unnamed mark" feature: Like marks for the ":g" command, but place and + unplace them with commands before doing something with the lines. + Highlight the marked lines somehow. + + +Digraphs: +7 Make "ga" show the digraph for a character, if it exists. + Also the keymap? +- Make it possible to enter "r<C-E>" and "r<C-Y>" (get character from line + below/above). +- Use digraph table to tell Vim about the collating sequence of special + characters? +8 Add command to remove (all) digraphs. (Brown) +7 Support different sets of digraphs (depending on the character set?). At + least Latin1/Unicode, Latin-2, MS-DOS (esp. for Win32). + + +Writing files: +- In vim_rename(), should lock "from" file when deleting "to" file for + systems other than Amiga. Avoids problems with unexpected longname to + shortname conversion. +8 write mch_isdevice() for Amiga, Mac, VMS, etc. +8 When appending to a file, Vim should also make a backup and a 'patchmode' + file. +8 'backupskip' doesn't write a backup file at all, a bit dangerous for some + applications. Add 'backupelsewhere' to write a backup file in another + directory? Or add a flag to 'backupdir'? +7 The 'directory' option supports changing path separators to "%" to make + file names unique, also support this for 'backupdir'. (Mikolaj Machowski) +6 Add an option to write a new, numbered, backup file each time. Like + 'patchmode', e.g., 'backupmode'. +6 Make it possible to write 'patchmode' files to a different directory. + E.g., ":set patchmode=~/backups/*.orig". (Thomas) +6 Add an option to prepend something to the backup file name. E.g., "#". + Or maybe allow a function to modify the backup file name? +8 Only make a backup when overwriting a file for the first time. Avoids + losing the original when writing twice. (Slootman) +7 On non-Unix machines, also overwrite the original file in some situations + (file system full, it's a link on an NFS partition). +7 When editing a file, check that it has been change outside of Vim more + often, not only when writing over it. E.g., at the time the swap file is + flushed. Or every ten seconds or so (use the time of day, check it before + waiting for a character to be typed). +8 When a file was changed since editing started, show this in the status + line of the window, like "[time]". + Make it easier to reload all outdated files that don't have changes. + Automatic and/or with a command. + + +Substitute: +8 Make it easier to replace in all files in the argument list. E.g.: + ":argsub/oldword/newword/". Works like ":argdo %s/oldword/newword/g|w". +- :s///p prints the line after a substitution. +- With :s///c replace \&, ~, etc. when showing the replacement pattern. +8 With :s///c allow scrolling horizontally when 'nowrap' is effective. + Also allow a count before the scrolling keys. +- Add number option to ":s//2": replace second occurrence of string? Or: + :s///N substitutes N times. +- Add answers to ":substitute" with 'c' flag, used in a ":global", e.g.: + ":g/pat1/s/pat2/pat3/cg": 'A' do all remaining replacements, 'Q' don't do + any replacements, 'u' undo last substitution. +7 Substitute in a block of text. Use {line}.{column} notation in an Ex + range, e.g.: ":1.3,$.5s" means to substitute from line 1 column 3 to the + last line column 5. +5 Add commands to bookmark lines, display bookmarks, remove bookmarks, + operate on lines with bookmarks, etc. Like ":global" but with the + possibility to keep the bookmarks and use them with several commands. + (Stanislav Sitar) + + +Mouse support: +7 Win32: Add patch for 5-button mouse. (Michael Geddes 2001 Nov 26) +8 Add 'o' flag to 'mouse'? +7 Be able to set a 'mouseshape' for the popup menu. +8 Add 'mouse' flag, which sets a behavior like Visual mode, but automatic + yanking at the button-up event. Or like Select mode, but typing gets you + out of Select mode, instead of replacing the text. (Bhaskar) +7 Checkout sysmouse() for FreeBSD console mouse support. +- Implement mouse support for the Amiga console. +- Using right mouse button to extend a blockwise selection should attach to + the nearest corner of the rectangle (four possible corners). +- Precede mouse click by a number to simulate double clicks?!? +- When mouse click after 'r' command, get character that was pointed to. + + +Crypt and security: +8 Also crypt the swapfile, each block separately. Change mf_write() and + mf_read(). How to get b_p_key to these functions? +7 Support a stronger encryption. Jason Holt implemented AES (May 6 2003). +8 Lock all used memory so that it doesn't get swapped to disk (uncrypted). + Patch by Jason Holt, 2003 May 23. + + +Argument list: +6 Add command to put all filenames from the tag files in the argument list. + When given an argument, only use the files where that argument matches + (like `grep -l ident`) and jump to the first match. +6 Add command to form an args list from all the buffers? + + +Registers: +8 Don't display empty registers with ":display". (Etienne) +8 Make the # register writable, so that it can be restored after jumping + around in windows. +8 Add put command that overwrites existing text. Should also work for + blocks. Useful to move text around in a table. Works like using "R ^R r" + for every line. +6 When yanking into the unnamed registers several times, somehow make the + previous contents also available (like it's done for deleting). What + register names to use? g"1, g"2, etc.? +- When appending to a register, also report the total resulting number of + lines. Or just say "99 more lines yanked", add the "more". +- When inserting a register in Insert mode with CTRL-R, don't insert comment + leader when line wraps? +- The ":@r" commands should take a range and execute the register for each + line in the range. +- Add "P" command to insert contents of unnamed register, move selected text + to position of previous deleted (to swap foo and bar in " + foo") +8 Should be able to yank and delete into the "/ register. + How to take care of the flags (offset, magic)? +7 Add ! register, for shell commands. (patch from Grenie) + +Debug mode: +7 Add something to enable debugging when a remote message is received. +8 Add breakpoints for setting an option +8 Add breakpoits for assigning to a variable. +7 Add a watchpoint in the debug mode: An expression that breaks execution + when evaluating to non-zero. +7 Store the history from debug mode in viminfo. +7 Make the debug mode history available with histget() et al. + + +Various improvements: +8 Add ":rename" command: rename the file of the current buffer and rename + the buffer. Buffer may be modified. +7 Add the MzScheme interface. Patch on http://iamphet.nm.ru/scheme/ + (Sergey Khorev) +6 In the quickfix window statusline add the command used to get the list of + errors, e.g. ":make foo", ":grep something *.c". +6 Python interface: add vim.message() function. (Michal Vitecek, 2002 Nov 5) +7 Support using ":vert" with User commands. Add expandable items <vert>. + Do the same for ":browse" and ":confirm"? + For ":silent" and ":debug" apply to the whole user command. +7 Allow a window not to have a statusline. Makes it possible to use a + window as a buffer-tab selection. +7 Add an invisible buffer which can be edited. For use in scripts that want + to manipulate text without changing the window layout. +8 Add a command to revert to the saved version of file; undo or redo until + all changes are gone. +8 Make 'statusline' local, so that each window can have a different value. + But should it also be local to a buffer? (Yegappan Lakshmanan has a patch, + 2002 feb 15) +7 Add a ":cpfile", go in the other direction as ":cnfile". +6 "vim -q -" should read the list of errors from stdin. (Gautam Mudunuri) +8 In the gzip plugin, also recognize *.gz.orig, *.gz.bak, etc. Like it's + done for filetype detection. Patch from Walter Briscoe, 2003 Jul 1. +8 Add "--remote-fail": When contacting the server fails, exit Vim. + Add "--remote-self": When contacting the server fails, do it in this Vim. + Overrules the default of "--remote-send" to fail and "--remote" to do it + in this Vim. +8 When Vim was started without a server, make it possible to start one, as + if the "--servername" argument was given. ":startserver <name>"? +8 No address range can be used before the command modifiers. This makes + them difficult to use in a menu for Visual mode. Accept the range and + have it apply to the following command. +8 Add the possibility to set 'fileformats' to force a format and strip other + CR characters. For example, for "dos" files remove CR characters at the + end of the line, so that a file with mixed line endings is cleaned up. + To just not display the CR characters: Add a flag to 'display'? +7 Add a "-@ filelist" argument: read file names from a file. (David Kotchan + has a patch for it) +7 Some compilers give error messages in which the file name does not have a + path. Be able to specify that 'path' is used for these files. +8 Add term entries for function keys on xterm with alt and ctrl (new in pl + 94). E.g., Control adds ";5" in "<Esc>[20;5~". Find a generic way to + prepend a modifier in console mode, to avoid having to specify each + individual modified key. + Steve Wall has a patch (2002 Mar 12) for adding function keys up to 37, + with modifiers. +7 Xterm sends <Esc>O3F for <M-End>. Similarly for other <M-Home>, <M-Left>, + etc. Combinations of Alt, Ctrl and Shift are also possible. Recognize + these to avoid inserting the raw byte sequence, handle like the key + without modifier (unless mapped). +8 Add ":breakdel *": delete all breakpoints. +7 Support ":browse edit" in console, using explorer.vim? +6 Add "gG": like what "gj" is to "j": go to the N'th window line. +8 Add command like ":normal" that accepts <Key> notation like ":map". +9 Support ACLs on more systems. +7 Add ModeMsgVisual, ModeMsgInsert, etc. so that each mode message can be + highlighted differently. +8 Allow using "**" as a wildcard in commands like ":next" and ":args". +8 Provide a way to avoid wildcard expansion. Use double quotes, like in the + shell? :edit "my[file].txt" (currently works if there is no "myf.txt") +7 Add a message area for the user. Set some option to reserve space (above + the command line?). Use an ":echouser" command to display the message + (truncated to fit in the space). +7 Add %s to 'keywordprg': replace with word under the cursor. (Zellner) +8 Support printing on Unix. Can use "lpansi.c" as an example. (Bookout) +8 Add put command that replaces the text under it. Esp. for blockwise + Visual mode. +7 Enhance termreponse stuff: Add t_CV(?): pattern of term response, use + regexp: "\e\[[>?][0-9;]*c", but only check just after sending t_RV. +7 Add "g|" command: move to N'th column from the left margin (after wrapping + and applying 'leftcol'). Works as "|" like what "g0" is to "0". +7 Add patch from Wall for this one ( ~/Mail/oldmail/wall/in.00019 ): + 'flipcase' variable: upper/lowercase pairs. + Insert comma's between pairs and allow a range, make it look like + 'isfname'. E.g. ":set flipcase=a-zA-Z,xX,23-33:143-153". The colon to + separate the from and to part is optional. +7 Support setting 'equalprg' to a user function name. +9 Add cursor-column highlighting. Enable it with 'cursorcolumn' option, set + highlighting with "CursorColumn" group. Useful for aligning text. + Also cursor-row highlighting. + Patch from Yasuhiro Matsumoto for underlining the cursor line, 2004 Mar 24. + Alternatie: when 'number' is set highlight the number of the current line. +7 Highlight the characters after the end-of-line differently. +7 When 'whichwrap' contains "l", "$dl" should join lines? +8 Include a connection to an external program through a pipe? See patches + from Felbinger for a mathematica interface. + Or use emacs server kind of thing? +8 Add an argument to configure to use $CFLAGS and not modify it? (Mooney) +8 Enabling features is a mix of configure arguments and defines in + feature.h. How to make this consistent? Feature.h is required for + non-unix systems. Perhaps let configure define CONF_XXX, and use #ifdef + CONF_XXX in feature.h? Then what should min-features and max-features do? +8 Add "g^E" and "g^Y", to scroll a screen-full line up and down. +6 Add ":timer" command, to set a command to be executed at a certain + interval, or once after some time has elapsed. (Aaron) +8 Add ":confirm" handling in open_exfile(), for when file already exists. +8 Use confirm/dialog stuff to ask the user, when a file has changed outside + of Vim, if he wants to reload it. Triggered when focus gained, after + shell command, when entering another buffer, etc.. + Also do this when editing a new file, and another application creates + the file before doing ":w" in Vim. + Also check if the file protection has changed. When checking a file into + RCS it is made read-only, when checking out it is made read-write. +8 When quitting with changed files, make the dialog list the changed file + and allow "write all", "discard all", "write some". The last one would + then ask "write" or "discard" for each changed file. Patch in HierAssist + does something like this. (Shah) +7 Use growarray for replace stack. +7 Have a look at viH (Hellenic or Greek version of Vim). But a solution + outside of Vim might be satisfactory (Haritsis). +3 Make "2d%" work like "d%d%" instead of "d2%"? +8 Make "more" prompt accept command characters, like "hit-enter" prompt? + Or extend it with more commands, like "less": 'b' for back, 'j' for one + line down, etc. +8 For the "--more--" prompt, support the 'b'ack command for more commands. + Possible implementation: Do it at a very low level, caching the lines that + are on the screen (with highlight attributes). Avoids that changes have + to be made for all functions that list something. +7 "g CTRL-O" jumps back to last used buffer. Skip CTRL-O jumps in the same + buffer. Make jumplist remember the last ten accessed buffers? +- Keep a list of most recently used files for each window, use "[o" to go + back (older file) and "]n" to go forward (newer file) (like ^O and ^I for + jumps) (Webb). Use ":files" and ":ls" to list the files in history order. +7 Add a history of recently accessed buffer. Maybe make "2 CTRL-^" jump to + the 2nd previously visited buffer, "3 CTRL-^" to the third, etc. Or use + "3 g CTRL-^" for this? +7 Add an option to set the width of the 'number' column. Eight positions is + often more than needed. Or adjust the width to the length of the file? + Add patch that adds 'numberlen' option. (James Harvey) + Other patch with min and max from Emmanuel Renieris (2002 Jul 24) + Other patch without an option by Gilles Roy (2002 Jul 25) +- Add code to disable the CAPS key when going from Insert to Normal mode. +- Set date/protection/etc. of the patchfile the same as the original file. +- Use growarray for termcodes[] in term.c +- Add <window-99>, like <cword> but use filename of 99'th window. +7 Add a way to change an operator to always work characterwise-inclusive + (like "v" makes the operator characterwise-exclusive). "x" could be used. +- Make a set of operations on list of names: expand wildcards, replace home + dir, append a string, delete a string, etc. +- Remove mktemp() and use tmpname() only? Ctags does this. +- When replacing environment variables, and there is one that is not set, + turn it into an empty string? Only when expanding options? (Hiebert) +- Option to set command to be executed instead of producing a beep (e.g. to + call "play newbeep.au"). +- Add option to show the current function name in the status line. More or + less what you find with "[[k", like how 'cindent' recognizes a function. + (Bhatt). +- "[r" and "]r": like "p" and "P", but replace instead of insert (esp. for + blockwise registers). +- Add 'timecheck' option, on by default. Makes it possible to switch off the + timestamp warning and question. (Dodt). +- Add an option to set the time after which Vim should check the timestamps + of the files. Only check when an event occurs (e.g., character typed, + mouse moved). Useful for non-GUI versions where keyboard focus isn't + noticeable. +9 When using ":w <fname>" it's possible that this file is loaded in another + buffer. Give a warning right away, don't wait for a shell command. +- Make 'smartcase' work even though 'ic' isn't set (Webb). +7 Add ":justify" command. Patch from Vit Stradal 2002 Nov 25. +7 When formatting text, allow to break the line at a number of characters. + Use an option for this: 'breakchars'? Useful for formatting Fortran code. +- Add flag to 'formatoptions' to be able to format book-style paragraphs + (first line of paragraph has larger indent, no empty lines between + paragraphs). Complements the '2' flag. Use '>' flag when larger indent + starts a new paragraph, use '<' flag when smaller indent starts a new + paragraph. Both start a new paragraph on any indent change. +8 Add 'formatexpr' option: Used for formatting operator "gq" instead of the + builtin formatting or 'formatprg'. +8 Allow using a trailing space to signal a paragraph that continues on the + next line (MIME text/plain; format=flowed, RFC 2646). Can be used for + continuous formatting. Could use 'autoformat' option, which specifies a + regexp which triggers auto-formatting (for one line). + ":set autoformat=\\s$". +- Be able to redefine where a sentence stops. Use a regexp pattern? +7 Add command "g)" to go to the end of a sentence, "g(" to go back to the + end of a sentence. (Servatius Brandt) +- Be able to redefine where a paragraph starts. For "[[" where the '{' is + not in column 1. +6 Add ":cdprev": go back to the previous directory. Need to remember a + stack of previous directories. We also need ":cdnext". +7 Should ":cd" for MS-DOS go to $HOME, when it's defined? +- Make "gq<CR>" work on the last line in the file. Maybe for every operator? +8 findmatchlimit() should be able to skip comments. Solves problem of + matching the '{' in /* if (foo) { */ (Fiveash) +- findmatch() should be adjusted for Lisp. See remark at get_lisp_indent(). + Esp. \( and \) should be skipped. (Dorai Sitaram, incomplete patch Mar 18) +- Add more redirecting of Ex commands: + :redir @> register (append) + :redir # bufname + :redir #> bufname (append) + :redir = variable + :redir => variable (append) +- Setting of options, specifically for a buffer or window, with + ":set window.option" or ":set buffer.option=val". Or use ":buffer.set". + Also: "buffer.map <F1> quit". +6 Would it be possible to change the color of the cursor in the Win32 + console? (Klaus Hast) +- Add :delcr command: + *:delcr* + :[range]delcr[!] Check [range] lines (default: whole buffer) for lines + ending in <CR>. If all lines end in <CR>, or [!] is + used, remove the <CR> at the end of lines in [range]. + A CTRL-Z at the end of the file is removed. If + [range] is omitted, or it is the whole file, and all + lines end in <CR> 'textmode' is set. {not in Vi} +- Should integrate addstar() and file_pat_to_reg_pat(). +- When working over a serial line with 7 bit characters, remove meta + characters from 'isprint'. +- Use fchdir() in init_homedir(), like in FullName(). +- In win_update(), when the GUI is active, always use the scrolling area. + Avoid that the last status line is deleted and needs to be redrawn. +- That "cTx" fails when the cursor is just after 'x' is Vi compatible, but + may not be what you expect. Add a flag in 'cpoptions' for this? More + general: Add an option to allow "c" to work with a null motion. +- Give better error messages by using errno (strerror()). +- Give "Usage:" error message when command used with wrong arguments (like + Nvi). +- Make 'restorescreen' option also work for xterm (and others), replaces the + SAVE_XTERM_SCREEN define. +7 Support for ":winpos" In xterm: report the current window position. +- Give warning message when using ":set t_xx=asdf" for a termcap code that + Vim doesn't know about. Add flag in 'shortmess'? +6 Add ":che <file>", list all the include paths which lead to this file. +- For a commandline that has several commands (:s, :d, etc.) summarize the + changes all together instead of for each command (e.g. for the rot13 + macro). +- Add command like "[I" that also shows the tree of included files. +- Add command like ":ts" that shows the output of "[I" and asks for a match + to jump to. (Zellner) +- ":set sm^L" results in ":set s", because short names of options are also + expanded. Is there a better way to do this? +- Add ":@!" command, to ":@" like what ":source!" is to ":source". +8 Add ":@:!": repeat last command with forceit set. +- Should be possible to write to a device, e.g. ":w! /dev/null". +- Add 't_normal': Used whenever t_me, t_se, t_ue or t_Zr is empty. +- ":cab map test ^V| je", ":cunab map" doesn't work. This is vi compatible! +- CTRL-W CTRL-E and CTRL-W CTRL-Y should move the current window up or down + if it is not the first or last window. +- Include-file-search commands should look in the loaded buffer of a file (if + there is one) instead of the file itself. +7 Change 'nrformats' to include the leader for each format. Example: + nrformats=hex:$,binary:b,octal:0 + Add setting of 'nrformats' to syntax files. +- 'path' can become very long, don't use NameBuff for expansion. +- When unhiding a hidden buffer, put the same line at top of the window as + the one before hiding it. Or: keep the same relative cursor position (so + many percent down the windows). +- Make it possible for the 'showbreak' to be displayed at the end of the + line. Use a comma to separate the part at the end and the start of the + line? Highlight the linebreak characters, add flag in 'highlight'. +- Some string options should be expanded if they have wildcards, e.g. + 'dictionary' when it is "*.h". +- Use a specific type for number and boolean options, making it possible to + change it for specific machines (e.g. when a long is 64 bit). +- Add option for <Insert> in replace mode going to normal mode. (Nugent) +- Add a next/previous possibility to "[^I" and friends. +- Add possibility to change the HOME directory. Use the directory from the + passwd file? (Antwerpen) +- When doing "[^I" or "[^D" add position to tag stack. +- Add command to put current position to tag stack: ":tpush". +8 Add commands to push and pop all or individual options. ":setpush tw", + ":setpop tw", ":setpush all". Maybe pushing/popping all options is + sufficient. ":setflush" resets the option stack? + How to handle an aborted mapping? Remember position in tag stack when + mapping starts, restore it when an error aborts the mapping? +- Use a builtin grep command for ":grep"? Makes it possible to add the + column number. Can use the code of ":helpgrep". + Also support using "**" in filename, so that a directory tree can be + searched. +- Change ":fixdel" into option 'fixdel', t_del will be adjusted each time + t_bs is set? (Webb) +- "gc": goto character, move absolute character positions forward, also + counting newlines. "gC" goes backwards (Weigert). +- When doing CTRL-^, redraw buffer with the same topline (Demirel). Store + cursor row and window height to redraw cursor at same percentage of window + (Webb). +- Besides remembering the last used line number of a file, also remember the + column. Use it with CTRL-^ et. al. +- Check for non-digits when setting a number option (careful when entering + hex codes like 0xff). +- Add option to make "." redo the "@r" command, instead of the last command + executed by it. Also to make "." redo the whole mapping. Basically: redo + the last TYPED command. +- Support URL links for ^X^F in Insert mode, like for "gf". +- Support %name% expansion for "gf" on Windows. +- Make "gf" work on "file://c:/path/name". "file:/c:/" and "file:///c:/" + should also work? +- Add 'urlpath', used like 'path' for when "gf" used on an URL? +8 When using "gf" on an absolute file name, while editing a remote file + (starts with scp:// or http://) should prepend the method and machine + name. +- When finding an URL or file name, and it doesn't exist, try removing a + trailing '.'. +- Add ":path" command modifier. Should work for every command that takes a + file name argument, to search for the file name in 'path'. Use + find_file_in_path(). +- Highlight control characters on the screen: Shows the difference between + CTRL-X and "^" followed by "X" (Colon). +- Integrate parsing of cmdline command and parsing for expansion. +- Create a program that can translate a .swp file from any machine into a + form usable by Vim on the current machine. +- Add ":noro" command: Reset 'ro' flag for all buffers, except ones that have + a readonly file. ":noro!" will reset all 'ro' flags. +- Add a variant of CTRL-V that stops interpretation of more than one + character. For entering mappings on the command line where a key contains + several special characters, e.g. a trailing newline. +- Add regex for 'paragraphs' and 'sections': 'parare' and 'sectre'. Combine + the two into a regex for searching. (Ned Konz) +- Make '2' option in 'formatoptions' also work inside comments. +- Add 's' flag to 'formatoptions': Do not break when inside a string. (Dodt) +- When window size changed (with the mouse) and made too small, set it back + to the minimal size. +- Add "]>" and "[<", shift comment at end of line (command; /* comment */). +- Should not call cursorcmd() for each vgetc() in getcmdline(). +- ":split file1 file2" adds two more windows (Webb). +- Don't give message "Incomplete last line" when editing binary file. +- Add ":a", ":i" for preloading of named buffers. +- Allow autowrite when doing ":e file" (with an option 'eaw'). +- Allow a "+command" argument before each file name in the Vim command line: + "vim +123 file1 +234 file2 +345 file3". ??? +- When entering text, keep other windows on same buffer updated (when a line + entered)? +- Check out how screen does output optimizing. Apparently this is possible + as an output filter. +- In dosub() regexec is called twice for the same line. Try to avoid this. +- Window updating from memline.c: insert/delete/replace line. +- Optimize ml_append() for speed, esp. for reading a file. +- V..c should keep indent when 'ai' is set, just like [count]cc. +- Updatescript() can be done faster with a string instead of a char. +- Screen updating is inefficient with CTRL-F and CTRL-B when there are long + lines. +- Uppercase characters in ex commands can be made lowercase? +8 Add option to show characters in text not as "|A" but as decimal ("^129"), + hex ("\x81") or octal ("\201") or meta (M-x). Nvi has the 'octal' option + to switch from hex to octal. Vile can show unprintable characters in hex + or in octal. +7 Tighter integration with xxd to edit binary files. Make it more + easy/obvious to use. Command line argument? +- How does vi detect whether a filter has messed up the screen? Check source. + After ":w !command" a wait_return? +- Improve screen updating code for doput() (use s_ins()). +- With 'p' command on last line: scroll screen up (also for terminals without + insert line command). +- Use insert/delete char when terminal supports it. +- Optimize screen redraw for slow terminals. +- Optimize "dw" for long row of spaces (say, 30000). +- Add "-d null" for editing from a script file without displaying. +- In Insert mode: Remember the characters that were removed with backspace + and re-insert them one at a time with <key1>, all together with <key2>. +- Amiga: Add possibility to set a keymap. The code in amiga.c does not work + yet. +- Implement 'redraw' option. +- Add special code to 'sections' option to define something else but '{' or + '}' as the start of a section (e.g. one shiftwidth to the right). +- Add 'indent' option: Always use this amount of indent when starting a new + line and when formatting text. +- Use pipes for filtering on Unix. Requires using fork() to be able to read + and write at the same time, or some select() mechanism. +7 Allow using Vim in a pipe: "ls | vim -u xxx.vim - | yyy". Only needs + implementing ":w" to stdout in the buffer that was read from stdin. +8 Allow opening an unnamed buffer with ":e !cmd" and ":sp !cmd". Vile can + do it. +- Add commands like ]] and [[ that do not include the line jumped to. +- When :unab without matching "from" part and several matching "to" parts, + delete the entry that was used last, instead of the first in the list. +- Add text justification option. +- Set boolean options on/off with ":set paste=off", ":set paste=on". +- After "inv"ing an option show the value: ":set invpaste" gives "paste is + off". +- Check handling of CTRL-V and '\' for ":" commands that do not have TRLBAR. +- When a file cannot be opened but does exist, give error message. +- Amiga: When 'r' protection bit is not set, file can still be opened but + gives read errors. Check protection before opening. +- When writing check for file exists but no permission, "Permission denied". +- If file does not exists, check if directory exists. +- MSDOS: although t_cv and t_ci are not set, do invert char under cursor. +- Settings edit mode: make file with ":set opt=xx", edit it, parse it as ex + commands. +- ":set -w all": list one option per line. +- Amiga: test for 'w' flag when reading a file. +- :table command (Webb) +- Add new operator: clear, make area white (replace with spaces): "g ". +- Make it possible for a user to define a new operator. Implementation with + internal scripting language or Perl? +- Add command to ":read" a file at a certain column (blockwise read?). +- Add sort of replace mode where case is taken from the old text (Goldfarb). +- Allow multiple arguments for ":read", read all the files. +- Support for tabs in specific columns: ":set tabcol=8,20,34,56" (Demirel). +- Add 'searchdir' option: Directories to search for file name being edited + (Demirel). +- Modifier for the put command: Change to linewise, charwise, blockwise, etc. +- Add commands for saving and restoring options ":set save" "set restore", + for use in macro's and the like. +- Keep output from listings in a window, so you can have a look at it while + working in another window. Put cmdline in a separate window? +- Add possibility to put output of ex commands in a buffer or file, e.g. for + ":set all". ":r :set all"? +- 'edit' option: When off changing the buffer is not possible (Really + read-only mode). +- When the 'equalalways' option is set, creating a new window should not + result in windows to become bigger. Deleting a window should not result in + a window to become smaller (Webb). +- When resizing the whole Vim window, the windows inside should be resized + proportionally (Webb). +- Include options directly in option table, no indirect pointers. Use + mkopttab to make option table? +- When doing ":w dir", where "dir" is a directory name, write the current + file into that directory, with the current file name (without the path)? +- Support for 'dictionary's that are sorted, makes access a lot faster + (Haritsis). +- Add "^Vrx" on the command line, replace with contents of register x. Used + instead of CTRL-R to make repeating possible. (Marinichev) +- Add "^Vb" on the command line, replace with word before or under the + cursor? +- Option to make a .swp file only when a change is made (Templeton). +- Support mapping for replace mode and "r" command (Vi doesn't do this)? +5 Add 'ignorefilecase' option: Ignore case when expanding file names. + ":e ma<Tab>" would also find "Makefile" on Unix. +8 Sorting of filenames for completion is wrong on systems that ignore case + of filenames. Add 'ignorefncase' option. When set, case in filenames is + ignored for sorting them. Patch by Mike Williams: + ~/vim/patches/ignorefncase. Also change what matches? Or use another + option name. +8 Should be able to compile Vim in another directory, with $(srcdir) set to + where the sources are. Add $(srcdir) in the Makefile in a lot of places. + (Netherton) +6 Make it configurable when "J" inserts a space or not. Should not add a + space after "(", for example. +5 When inserting spaces after the end-of-line for 'virtualedit', use tabs + when the user wants this (e.g., add a "tab" field to 'virtualedit'). + (Servatius Brandt) + + +From Elvis: +- Use "instman.sh" to install manpages? +- Add ":alias" command. +- fontchanges recognized "\\fB" etc. +- Search patterns: + \@ match word under cursor. + but do: + \@w match the word under the cursor? + \@W match the WORD under the cursor? +8 ":window" command: + :win + next window (up) + :win ++ idem, wrapping + :win - previous window (down) + :win -- idem, wrapping + :win nr to window number "nr" + :win name to window editing buffer "name" +7 ":cc" compiles a single file (default: current one). 'ccprg' option is + program to use with ":cc". Use ":compile" instead of ":cc"? + + +From Nvi: +- 'searchincr' option, alias for 'incsearch'? +- 'leftright' option, alias for 'nowrap'? +- Have a look at "vi/doc/vi.chart", for Nvi specialties. +8 Add 'keytime', time in 1/10 sec for mapping timeout? +- Add 'filec' option as an alternative for 'wildchar'. +6 Support Nvi command names as an alias: + :bg :hide + :fg fname :buf fname (with 'hidden' set?) + :dis b :ls + :Edit fname :split fname + :Fg fname :sbuf fname (with 'hidden' set?) + :Next :snext (can't do this, already use :Next) + :Previous :sprevious + :Tag :stag + + +From xvi: +- CTRL-_ : swap 8th bit of character. +- Add egrep-like regex type, like xvi (Ned Konz) or Perl (Emmanuel Mogenet) + + +From vile: +- When horizontal scrolling, use '>' for lines continuing right of a window. +- Support putting .swp files in /tmp: Command in rc.local to move .swp files + from /tmp to some directory before deleting files. + + +Far future and "big" extensions: +- Make it easy to setup Vim for groups of users: novice vi users, novice + Vim users, C programmers, xterm users, GUI users,... +- Change layout of blocks in swap file: Text at the start, with '\n' in + between lines (just load the file without changes, except for Mac). + Indexes for lines are from the end of the block backwards. It's the + current layout mirrored. +- Make it possible to edit a register, in a window, like a buffer. +- Add stuff to syntax highlighting to change the text (upper-case keywords, + set indent, define other highlighting, etc.). +- Mode to keep C-code formatted all the time (sort of on-line indent). +- Several top-level windows in one Vim session. Be able to use a different + font in each top-level window. +- Allow editing above start and below end of buffer (flag in 'virtualedit'). +- Smart cut/paste: recognize words and adjust spaces before/after them. +- Add open mode, use it when terminal has no cursor positioning. +- Special "drawing mode": a line is drawn where the cursor is moved to. + Backspace deletes along the line (from jvim). +- Implement ":Bset", set option in all buffers. Also ":Wset", set in all + windows, ":Aset, set in all arguments and ":Tset", set in all files + mentioned in the tags file. + Add buffer/arg range, like in ":2,5B%s/..." (do we really need this???) + Add search string: "B/*.c/%s/.."? Or ":F/*.c/%s/.."? +- Support for underlining (underscore-BS-char), bold (char-BS-char) and other + standout modes switched on/off with , 'overstrike' option (Reiter). +- Add vertical mode (Paul Jury, Demirel): "5vdw" deletes a word in five + lines, "3vitextESC" will insert "text" in three lines, etc.. +4 Recognize l, #, p as 'flags' to EX commands: + :g/RE/#l shall print lines with line numbers and in list format. + :g/RE/dp shall print lines that are deleted. + POSIX: Commands where flags shall apply to all lines written: list, + number, open, print, substitute, visual, &, z. For other commands, flags + shall apply to the current line after the command completes. Examples: + :7,10j #l Join the lines 7-10 and print the result in list +- Allow two or more users to edit the same file at the same time. Changes + are reflected in each Vim immediately. Could work with local files but + also over the internet. See http://www.codingmonkeys.de/subethaedit/. + + +vim:tw=78:sw=4:sts=4:ts=8:ft=help:norl: +vim: set fo+=n :
