 							*known-bugs*
 -------------------- Known bugs and current work -----------------------
 Include src/po/vim.pot ?
-See if resizing a terminal can be fixed.
 Vim9 script:
+- line continuation at script level:
+eval_to_string_skip(), test with :throw
+eval1_emsg(), pass "eap", test with :execute, :echomsg, :echoerr
+handle_subscript() - call_func_rettv() - get_func_tv()
+	func(
+	    args arg)
+callers of get_func_tv():
+	eval_func()
+	ex_call()
+function arguments, test assert_equal() with lambda, test :function
+:import:
+others
+	eval_index()
+- test:
+	[1,
+	 2,
+	 3]->Func()
 Making everything work:
+- "nr += 4"  gives "already defined" error.
 - Error for "g:var: string = 'value'"
 - Make func()->append('$') work - value is last argument, not first. #6305
+- in Vim9 script expressions are evaluated differently, not using a type.
+e.g. "'' == 0" does not give an error and evaluates to true.
 - possible memory leak in test_vim9_func through compile_nested_function.
 - memory leaks in test_vim9_expr
 - memory leaks in test_vim9_script
 - more return types depending on the first argument, like sort().
 - Check that when sourcing a Vim9 script, only the global items can be used.
 - inline call to map() and filter()
 - compile "skip" argument of searchpair()
 - compile "expr" and "call" expression of a channel in channel_exe_cmd()?
 Popup windows:
-- With some sequence get get hidden finished terminal buffer. (#5768)
-Cannot close popup terminal (#5744)
-Buffer can't be wiped, gets status "aF". (#5764)
-Is buf->nwindows incorrect?
-- popup_clear() and popup_close() should close the terminal popup, and
-make the buffer hidden. #5745
 - Cursor not updated before a redraw, making it jump. (#5943)
 - With terminal in popup, allow for popup_hide() to temporarily hide it.?
 - Fire some autocommand event after a new popup window was created and
 positioned?  PopupNew?  Could be used to set some options or move it out of
 the way. (#5737)
 The buffer list and windows are locked, no changes possible
 How about removing Atari MiNT support?
 src/Make_mint.mak, src/os_mint.h, matches with __MINT__
+Add the <=> (spaceship) operator and "cond ?< expr ?= expr ?> expr"
+replace this:
+	let left = GetLeftFunc()
+	let right = GetRightFunc()
+	let res = left < right ? lower : left == right ? equal : upper
+by:
+	let res = GetLeftFunc() <=> GetRightFunc() ?< lower ?= equal ?> upper
 Patch to make :q work with local arglist. (Christian Brabandt, #6286)
 Patch to fix drawing error with DirectX. (James Grant, #5688)
 Causes flicker on resizing. Workaround from Ken Takata.
 How about only setting the attribute when part of the Vim window is offscreen?
 window 2.  User expects 10 to be added to size of window 2. (Daniel Steinberg,
 #5443)
 Would be nice to set tab-local values for 'diffexpr' and 'diffopt'.  Use
 t:diffexpr_option t:diffopt_option? (#4782)
-v:register isn't reset early enough, may be used by next command.
-(Andy Massimino, #5294, possible fix in #5305)
 Internal diff doesn't handle binary file like external diff does. (Mike
 Williams, 2018 Oct 30)
 '[ mark in wrong column after put. (#4776)
 in some cases?  E.g. for ":write" when the changed flag was already off, the
 buffer didn't change at all.
 Line numbers in profile are off when function was defined with ":execute".
 (Daniel Hahler, #4511)
-Add a way to create an empty, hidden buffer.  Like doing ":new|hide".
-":let buf = bufcreate('name')
 Session file contains absolute paths when "curdir" is removed form
 'sessionoptions', making it impossible to have a session with a relative path.
 (#4450)
 Make a function to check for function-like type?
 Screen updated delayed when using CTRL-O u in Insert mode.
 (Barlik, #1191)  Perhaps because status message?
-Implement named arguments for functions:
+Implement named arguments for functions with optional arguments:
-func Foo(start, count = 1 all = 1)
+func Foo(start, count = 1, all = 1)
 call Foo(12, all = 0)
 Add a command to take a range of lines, filter them and put the output
 somewhere else.  :{range}copy {dest} !cmd
 Did maintainer reply?
 ml_get errors when reloading file. (Chris Desjardins, 2016 Apr 19)
 Also with latest version.
-Cannot delete a file with square brackets with delete(). (#696)
 Completion for input() does not expand environment variables. (chdiza, 2016
 Jul 25, #948)
 Patch to add 'systemencoding', convert between 'encoding' and this for file
 names, shell commands and the like.  (Kikuchan, 2010 Oct 14)
 Assume the system converts between the actual encoding of the filesystem to
 the system encoding (usually utf-8).
-'hlsearch' interferes with a Conceal match. (Rom Grk, 2016 Aug 9)
 MS-Windows: use WS_HIDE instead of SW_SHOWMINNOACTIVE in os_win32.c?
 Otherwise task flickers in taskbar.
 Repeating 'opfunc' in a function only works once. (Tarmean, 2016 Jul 15, #925)
 #1125
 Second problem in #966: ins_compl_add_tv() uses get_dict_string() multiple
 times, overwrites the one buffer. (Nikolay Pavlov, 2016 Aug 5)
-Possibly wrong value for seq_cur. (Florent Fayolle, 2016 May 15, #806)
 Filetype plugin for awk. (Doug Kearns, 2016 Sep 5)
 Patch to improve map documentation. Issue #799.
 We can use '. to go to the last change in the current buffer, but how about
 It's possible to add ",," to 'wildignore', an empty entry.  Causes problems.
 Reject the value? #710.
 When doing "vi buf.md" a BufNew autocommand for *.md is not triggered.
 Because of using the initial buffer? (Dun Peal, 2016 May 12)
-Add redrawtabline command. (Naruhiko Nishino, 2016 Jun 11)
 Neovim patch for utfc_ptr2char_len() https://github.com/neovim/neovim/pull/4574
 No test, needs some work to include.
 Patch to improve indenting for C++ constructor with initializer list.
 2016 Apr 25, #780)
 Patch to avoid redrawing tabline when the popup menu is visible.
 (Christian Brabandt, 2016 Jan 28)
-Patch to show search statistics. (Christian Brabandt, 2016 Jul 22)
 When the CursorMovedI event triggers, and CTRL-X was typed, a script cannot
 restore the mode properly. (Andrew Stewart, 2016 Apr 20)
 Do not trigger the event?
-Using ":windo" to set options in all windows has the side effect that it
-changes the window layout and the current window.  Make a variant that saves
-and restores.  Use in the matchparen plugin.
-Perhaps we can use ":windo <restore> {cmd}"?
-Patch to add <restore> to :windo, :bufdo, etc. (Christian Brabandt, 2015 Jan
-6, 2nd message)
-Alternative: ":keeppos" command modifier: ":keeppos windo {cmd}".
 Patch to fix display of listchars on the cursorline. (Nayuri Aohime, 2013)
 Update suggested by Yasuhiro Matsumoto, 2014 Nov 25:
 https://gist.github.com/presuku/d3d6b230b9b6dcfc0477
 Python: ":py raw_input('prompt')" doesn't work. (Manu Hack)
 Comparing nested structures with "==" uses a different comparator than when
 comparing individual items.
-Also, "'' == 0" evaluates to true, which isn't nice.
-Add "===" to have a strict comparison (type and value match).
-Add "==*" (?) to have a value match, but no automatic conversion, and v:true
-equals 1 and 1.0, v:false equals 0 and 0.0.?
 Using uninitialized memory. (Dominique Pelle, 2015 Nov 4)
 MS-Windows: When editing a file with a leading space, writing it uses the
 wrong name. (Aram, 2014 Nov 7)  Vim 7.4.
 Perhaps only the checks that can be done without looping over the dict or
 arguments.
 Problem with transparent and matchgroup.  Issue #475
-Patch to add :arglocal and :arglists. (Marcin Szamotulski, 2014 Aug 6)
 Spell files use a latin single quote. Unicode also has another single quote:
 0x2019.  (Ron Aaron, 2014 Apr 4)
 New OpenOffice spell files support this with ICONV.  But they are not
 compatible with Vim spell files.  The old files can no longer be downloaded.
 from?
 Problem with upwards search on Windows (works OK on Linux). (Brett Stahlman,
 2014 Jun 8)
-Include a plugin manager with Vim? Neobundle seems to be the best currently.
+Include a plugin manager with Vim? vim-plug seems to be the best currently:
+https://github.com/junegunn/vim-plug.
 Also Vundle: https://github.com/gmarik/vundle
+Or minpac: https://github.com/k-takata/minpac, since it leverages the builtin
+package feature.
 Long message about this from ZyX, 2014 Mar 23.  And following replies.
 Also see http://vim-wiki.mawercer.de/wiki/topic/vim%20plugin%20managment.html
 User view:
 - Support multiple sources, basically any http:// URL. Or a central place that
 will work for everybody (github?  redirects from vim.org?).
 VMS: Select() doesn't work properly, typing ESC may hang Vim.  Use sys$qiow
 instead. (Samuel Ferencik, 2013 Sep 28)
 Patch for XDG base directory support. (Jean François Bignolles, 2014 Mar 4)
 Remark on the docs.  Should not be a compile time feature.  But then what?
+Also see #2034.
 Completion of ":e" is ":earlier", should be ":edit".  Complete to the matching
 command instead of doing this alphabetically. (Mikel Jorgensen)
 Patch to define macros for hardcoded values. (Elias Diem, 2013 Dec 14)
 Patch to add {lhs} to :mapclear: clear all maps starting with {lhs}.
 (Christian Brabandt, 2013 Dec 9)
 Exception caused by argument of return is not caught by try/catch.
 (David Barnett, 2013 Nov 19)
+Bug in try/catch: return with invalid compare throws error that isn't caught.
+(ZyX, 2011 Jan 26)
+try/catch not working for argument of return. (Matt Wozniski, 2008 Sep 15)
+try/catch not working when inside a for loop. (ZyX, 2011 Jan 25)
 Patch to fix that 'cedit' is recognized after :normal. (Christian Brabandt,
 2013 Mar 19, later message)
 Patch to view coverage of the tests. (Nazri Ramliy, 2013 Feb 15)
 In the ATTENTION message about an existing swap file, mention the name of the
 process that is running.  It might actually be some other program, e.g. after
 a reboot.
 patch to add "combine" flag to  syntax commands. (so8res, 2012 Dec 6)
+Patch to add "combine" to :syntax, combines highlight attributes. (Nate
+Soares, 2012 Dec 3)
 Syntax update problem in one buffer opened in two windows, bottom window is
 not correctly updated. (Paul Harris, 2012 Feb 27)
 Patch to add getsid(). (Tyru, 2011 Oct 2)  Do we want this?  Update Oct 4.
 When setqflist() uses a filename that triggers a BufReadCmd autocommand Vim
 doesn't jump to the correct line with :cfirst. (ZyX,  2011 Sep 18)
 Behavior of i" and a" text objects isn't logical. (Ben Fritz, 2013 Nov 19)
-Bug in try/catch: return with invalid compare throws error that isn't caught.
-(ZyX, 2011 Jan 26)
 When setting a local option value from the global value, add a script ID that
 indicates this, so that ":verbose set" can give a hint.  Check with options in
 the help file.
 Add local time at start of --startuptime output.
 Requires configure check for localtime().
 Use format year-month-day hr:min:sec.
-Patch to add "combine" to :syntax, combines highlight attributes. (Nate
-Soares, 2012 Dec 3)
 Patch to make ":hi link" also take arguments. (Nate Soares, 2012 Dec 4)
 Shell not recognized properly if it ends in "csh -f". (James Vega, 2009 Nov 3)
 Find tail?  Might have a / in argument.  Find space?  Might have space in
 path.
 Add cscope target to Makefile. (Tony Mechelynck, 2009 Jun 18, replies by
 Sergey Khorev)
 Consider making YankRing or something else that keeps a list of yanked text
 part of standard Vim.  The "1 to "9 registers are not sufficient.
+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.?
 After doing "su" $HOME can be the old user's home, thus ~root/file is not
 correct.  Don't use it in the swap file.
 Completion for ":buf" doesn't work properly on Win32 when 'shellslash' is off.
 Problem with 'ts' set to 9 and 'showbreak' to ">>>". (Matthew Winn, 2007 Oct
 1)
 In the swapfile dialog, add a H(elp) option that gives more info about what
 each choice does.  Similar to  ":help swap-exists-choices"
-try/catch not working for argument of return. (Matt Wozniski, 2008 Sep 15)
-try/catch not working when inside a for loop. (ZyX, 2011 Jan 25)
 ":tab help" always opens a new tab, while ":help" re-uses an existing window.
 Would be more consistent when an existing tab is re-used. (Tony Mechelynck)
 Add ":nofold".  Range will apply without expanding to closed fold.
 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" and ":helpgrep".
 More generic solution: support a filter (e.g., by calling a function).
 7   Add a command that goes back to the position from before jumping to the
-first quickfix location.  ":cbefore"?
+first quickfix location.
 Vi incompatibility:
 -   Try new POSIX tests, made after my comments. (Geoff Clare, 2005 April 7)
 Version 1.5 is in ~/src/posix/1.5. (Lynne Canal)
 8   With undo/redo only marks in the changed lines should be changed.  Other
 On the other hand, an ":undo" command in an Ex script only undoes the last
 change (e.g., use two :append commands, then :undo).
 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   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).
 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
 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)
 a problem with writing a file that starts with a dot. (Giacalone)
 9   In mac_expandpath() check that handling of backslashes is done properly.
 "Small" problems:
--   Can't disable terminal flow control, to enable the use of CTRL-S and
-CTRL-Q.  Add an option for it?
 -   When using e_secure in do_one_cmd() mention the command being executed,
 otherwise it's not clear where it comes from.
--   When the quickfix window is open and executing ":echo 'hello'" using the
-Command-line window, the text is immediately removed by the redrawing.
-(Michael Henry, 2008 Nov 1)
-Generic solution: When redrawing while there is a message on the
-cmdline, don't erase the display but draw over the existing text.
-Other solution, redraw after closing the cmdline window, before executing
-the command.
 9   For Turkish vim_tolower() and vim_toupper() also need to use utf_
 functions for characters below 0x80. (Sertacyildiz)
 9   When the last edited file is a help file, using '0 in a new Vim doesn't
 edit the file as a help file.  'filetype' is OK, but 'iskeyword' isn't,
 file isn't readonly, etc.
 items than other spell files with the ISO-8859-2 encoding, that causes
 problem when changing 'spelllang'.  There is no obvious way to fix this.
 -   Considering Hunspell 1.1.4:
 What does MAXNGRAMSUGS do?
 Is COMPLEXPREFIXES necessary when we have flags for affixes?
--   Support spelling words in CamelCase as if they were two separate words.
-Requires some option to enable it. (Timothy Knox)
 -   There is no Finnish spell checking file.  For openoffice Voikko is now
 used, which is based on Malaga: http://home.arcor.de/bjoern-beutel/malaga/
 (Teemu Likonen)
 8   ":mkspell" still takes much too long in Hungarian dictionary from
 hunspell.  Only solution appears to be to postpone secondary suffixes.
 they can give useful debugging info.  The whole call stack would be ideal.
 At least use this for error messages.
 7   Execute a function with standard option values.  No need to save and
 restore option values.  Especially useful for new options.  Problem: how
 to avoid a performance penalty (esp. for string options)?
-8   Add referring to key options with "&t_xx".  Both for "echo &t_xx" and
-":let &t_xx =".  Useful for making portable mappings.
 -   range for ":exec", pass it on to the executed command.  (Webb)
 8   ":{range}source": source the lines from the current file.
 	You can already yank lines and use :@" to execute them.
 	Most of do_source() would not be used, need a new function.
 	It's easy when not doing breakpoints or profiling.
 8   Use 'report' for ":bdel"?  (Krishna)  To avoid these messages when using a
 script.
 -   Delete message after new command has been entered and have waited for key.
 Perhaps after ten seconds?
 -   Make message history available in "msg" variables: msg1, msg2, .. msg9.
-8   When reading from stdin allow suppressing the "reading from stdin"
-message.
 9   Check handling of overwriting of messages and delays:
 Very wrong: errors while redrawing cause endless loop.
 When switching to another file and screen scrolls because of the long
 message and return must be typed, don't scroll the screen back before
 redrawing.
 Registers:
 8   Don't display empty registers with ":display". (Etienne)
 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
