43 For compiling see "src/INSTALLpc.txt". *win32-compiling* |

| 45 ============================================================================== | |
| 46 1. Known problems *windows95* *win32-problems* | |
| 47 | |
| 48 There are a few known problems with running in a console on Windows 95. As | |
| 49 far as we know, this is the same in Windows 98 and Windows ME. | |
| 50 | |
| 51 Comments from somebody working at Microsoft: "Win95 console support has always | |
| 52 been and will always be flaky". | |
| 53 1. Dead key support doesn't work. | |
| 54 2. Resizing the window with ":set columns=nn lines=nn" works, but executing | |
| 55 external commands MAY CAUSE THE SYSTEM TO HANG OR CRASH. | |
| 56 3. Screen updating is slow, unless you change 'columns' or 'lines' to a | |
| 57 non-DOS value. But then the second problem applies! | |
| 58 | |
| 59 If this bothers you, use the 32 bit MS-DOS version or the Win32 GUI version. | |
| 60 | |
| 61 When doing file name completion, Vim also finds matches for the short file | |
| 62 name. But Vim will still find and use the corresponding long file name. For | |
| 63 example, if you have the long file name "this_is_a_test" with the short file | |
| 64 name "this_i~1", the command ":e *1" will start editing "this_is_a_test". | |
| 65 | |
| 66 ============================================================================== | |
| 67 2. Startup *win32-startup* | |
| 68 | |
| 69 Current directory *win32-curdir* | |
| 70 | |
| 71 If Vim is started with a single file name argument, and it has a full path | |
| 72 (starts with "x:\"), Vim assumes it was started from the file explorer and | |
| 73 will set the current directory to where that file is. To avoid this when | |
| 74 typing a command to start Vim, use a forward slash instead of a backslash. | |
| 75 Example: > | |
| 76 | |
| 77 vim c:\text\files\foo.txt | |
| 78 | |
| 79 Will change to the "C:\text\files" directory. > | |
| 80 | |
| 81 vim c:/text\files\foo.txt | |
| 82 | |
| 83 Will use the current directory. | |
| 84 | |
| 85 | |
| 86 Term option *win32-term* | |
| 87 | |
| 88 The only kind of terminal type that the Win32 version of Vim understands is | |
| 89 "win32", which is built-in. If you set 'term' to anything else, you will | |
| 90 probably get very strange behavior from Vim. Therefore Vim does not obtain | |
| 91 the default value of 'term' from the environment variable "TERM". | |
| 92 | |
| 819 | 93 $PATH *win32-PATH* |
| 94 | |
| 95 The directory of the Vim executable is appended to $PATH. This is mostly to | |
| 5400 | 96 make "!xxd" work, as it is in the Tools menu. And it also means that when |
| 819 | 97 executable() returns 1 the executable can actually be executed. |

| 125 3. Restore screen contents *win32-restore* | |
| 126 | |
| 127 When 'restorescreen' is set (which is the default), Vim will restore the | |
| 128 original contents of the console when exiting or when executing external | |
| 129 commands. If you don't want this, use ":set nors". |'restorescreen'| | |

| 132 4. Using the mouse *win32-mouse* | |
| 133 | |
| 134 The Win32 version of Vim supports using the mouse. If you have a two-button | |
| 135 mouse, the middle button can be emulated by pressing both left and right | |
| 136 buttons simultaneously - but note that in the Win32 GUI, if you have the right | |
| 137 mouse button pop-up menu enabled (see 'mouse'), you should err on the side of | |
| 138 pressing the left button first. |mouse-using| | |
| 139 | |
| 140 When the mouse doesn't work, try disabling the "Quick Edit Mode" feature of | |
| 141 the console. | |

148 Support was removed in patch 7.4.1363. |
| 7 | 149 |
| 150 ============================================================================== | |
| 151 6. Win32 mini FAQ *win32-faq* | |
| 152 | |
| 153 Q. Why does the Win32 version of Vim update the screen so slowly on Windows 95? | |
| 154 A. The support for Win32 console mode applications is very buggy in Win95. | |
| 155 For some unknown reason, the screen updates very slowly when Vim is run at | |
| 156 one of the standard resolutions (80x25, 80x43, or 80x50) and the 16-bit DOS | |
| 157 version updates the screen much more quickly than the Win32 version. | |
| 158 However, if the screen is set to some other resolution, such as by ":set | |
| 159 columns=100" or ":set lines=40", screen updating becomes about as fast as | |
| 160 it is with the 16-bit version. | |
| 161 | |
| 162 WARNING: Changing 'columns' may make Windows 95 crash while updating the | |
| 163 window (complaints --> Microsoft). Since this mostly works, this has not | |
| 164 been disabled, but be careful with changing 'columns'. | |
| 165 | |
| 166 Changing the screen resolution makes updates faster, but it brings | |
| 167 additional problems. External commands (e.g., ":!dir") can cause Vim to | |
| 168 freeze when the screen is set to a non-standard resolution, particularly | |
| 169 when 'columns' is not equal to 80. It is not possible for Vim to reliably | |
| 170 set the screen resolution back to the value it had upon startup before | |
| 171 running external commands, so if you change the number of 'lines' or | |
| 172 'columns', be very, very careful. In fact, Vim will not allow you to | |
| 173 execute external commands when 'columns' is not equal to 80, because it is | |
| 174 so likely to freeze up afterwards. | |
| 175 | |
| 176 None of the above applies on Windows NT. Screen updates are fast, no | |
| 177 matter how many 'lines' or 'columns' the window has, and external commands | |
| 178 do not cause Vim to freeze. | |
| 179 | |
| 180 Q. So if the Win32 version updates the screen so slowly on Windows 95 and the | |
| 181 16-bit DOS version updates the screen quickly, why would I want to run the | |
| 182 Win32 version? | |
| 183 A. Firstly, the Win32 version isn't that slow, especially when the screen is | |
| 184 set to some non-standard number of 'lines' or 'columns'. Secondly, the | |
| 185 16-bit DOS version has some severe limitations: It can't do big changes and | |
| 186 it doesn't know about long file names. The Win32 version doesn't have these | |
| 187 limitations and it's faster overall (the same is true for the 32-bit DJGPP | |
| 188 DOS version of Vim). The Win32 version is smarter about handling the | |
| 189 screen, the mouse, and the keyboard than the DJGPP version is. | |
| 190 | |
| 191 Q. And what about the 16-bit DOS version versus the Win32 version on NT? | |
| 192 A. There are no good reasons to run the 16-bit DOS version on NT. The Win32 | |
| 193 version updates the screen just as fast as the 16-bit version does when | |
| 194 running on NT. All of the above disadvantages apply. Finally, DOS | |
| 195 applications can take a long time to start up and will run more slowly. On | |
| 196 non-Intel NT platforms, the DOS version is almost unusably slow, because it | |
| 197 runs on top of an 80x86 emulator. | |
| 198 | |
| 199 Q. How do I change the font? | |
| 22 | 200 A. In the GUI version, you can use the 'guifont' option. Example: > |
| 201 :set guifont=Lucida_Console:h15:cDEFAULT | |
| 202 < In the console version, you need to set the font of the console itself. | |
| 7 | 203 You cannot do this from within Vim. |
| 204 | |
| 205 Q. When I change the size of the console window with ':set lines=xx' or | |
| 206 similar, the font changes! (Win95) | |
| 207 A. You have the console font set to 'Auto' in Vim's (or your MS-DOS prompt's) | |
| 237 | 208 properties. This makes W95 guess (badly!) what font is best. Set an explicit |
| 7 | 209 font instead. |
| 210 | |
| 211 Q. Why can't I paste into Vim when running Windows 95? | |
| 212 A. In the properties dialog box for the MS-DOS window, go to "MS-DOS | |
| 213 Prompt/Misc/Fast pasting" and make sure that it is NOT checked. You should | |
| 214 also do ":set paste" in Vim to avoid unexpected effects. |'paste'| | |
| 215 | |
| 216 Q. How do I type dead keys on Windows 95, in the console version? | |
| 217 (A dead key is an accent key, such as acute, grave, or umlaut, that doesn't | |
| 218 produce a character by itself, but when followed by another key, produces | |
| 219 an accented character, such as a-acute, e-grave, u-umlaut, n-tilde, and so | |
| 220 on. Very useful for most European languages. English-language keyboard | |
| 221 layouts don't use dead keys, as far as we know.) | |
| 222 A. You don't. The console mode input routines simply do not work correctly in | |
| 223 Windows 95, and I have not been able to work around them. In the words | |
| 224 of a senior developer at Microsoft: | |
| 225 Win95 console support has always been and will always be flaky. | |
| 226 | |
| 227 The flakiness is unavoidable because we are stuck between the world of | |
| 228 MS-DOS keyboard TSRs like KEYB (which wants to cook the data; | |
| 229 important for international) and the world of Win32. | |

| 231 So keys that don't "exist" in MS-DOS land (like dead keys) have a | |
| 232 very tenuous existence in Win32 console land. Keys that act | |
| 233 differently between MS-DOS land and Win32 console land (like | |
| 234 capslock) will act flaky. | |
| 235 | |
| 236 Don't even _mention_ the problems with multiple language keyboard | |
| 237 layouts... | |
| 238 | |
| 239 You may be able to fashion some sort of workaround with the digraphs | |
| 240 mechanism. |digraphs| | |
| 241 | |
| 242 The best solution is to use the Win32 GUI version gvim.exe. Alternatively, | |
| 243 you can try one of the DOS versions of Vim where dead keys reportedly do | |
| 244 work. | |
| 245 | |
| 246 Q. How do I type dead keys on Windows NT? | |
| 247 A. Dead keys work on NT 3.51. Just type them as you would in any other | |
| 248 application. | |
| 249 On NT 4.0, you need to make sure that the default locale (set in the | |
| 250 Keyboard part of the Control Panel) is the same as the currently active | |
| 251 locale. Otherwise the NT code will get confused and crash! This is a NT | |
| 252 4.0 problem, not really a Vim problem. | |
| 253 | |
| 254 Q. I'm using Vim to edit a symbolically linked file on a Unix NFS file server. | |
| 255 When I write the file, Vim does not "write through" the symlink. Instead, | |
| 256 it deletes the symbolic link and creates a new file in its place. Why? | |
| 257 A. On Unix, Vim is prepared for links (symbolic or hard). A backup copy of | |
| 258 the original file is made and then the original file is overwritten. This | |
| 259 assures that all properties of the file remain the same. On non-Unix | |
| 260 systems, the original file is renamed and a new file is written. Only the | |
| 261 protection bits are set like the original file. However, this doesn't work | |
| 262 properly when working on an NFS-mounted file system where links and other | |
| 263 things exist. The only way to fix this in the current version is not | |
| 264 making a backup file, by ":set nobackup nowritebackup" |'writebackup'| | |
| 265 | |
| 22 | 266 Q. I'm using Vim to edit a file on a Unix file server through Samba. When I |
| 267 write the file, the owner of the file is changed. Why? | |
| 268 A. When writing a file Vim renames the original file, this is a backup (in | |
| 269 case writing the file fails halfway). Then the file is written as a new | |
| 270 file. Samba then gives it the default owner for the file system, which may | |
| 271 differ from the original owner. | |
| 272 To avoid this set the 'backupcopy' option to "yes". Vim will then make a | |
| 273 copy of the file for the backup, and overwrite the original file. The | |
| 274 owner isn't changed then. | |
| 275 | |
| 7 | 276 Q. How do I get to see the output of ":make" while it's running? |
| 277 A. Basically what you need is to put a tee program that will copy its input | |
| 278 (the output from make) to both stdout and to the errorfile. You can find a | |
| 1125 | 279 copy of tee (and a number of other GNU tools) at |
| 7 | 280 http://gnuwin32.sourceforge.net or http://unxutils.sourceforge.net |
| 281 Alternatively, try the more recent Cygnus version of the GNU tools at | |
| 282 http://www.cygwin.com Other Unix-style tools for Win32 are listed at | |
| 283 http://directory.google.com/Top/Computers/Software/Operating_Systems/Unix/Win32/ | |
| 284 When you do get a copy of tee, you'll need to add > | |
| 285 :set shellpipe=\|\ tee | |
| 286 < to your _vimrc. | |
| 287 | |
| 288 Q. I'm storing files on a remote machine that works with VisionFS, and files | |
| 289 disappear! | |
| 290 A. VisionFS can't handle certain dot (.) three letter extension file names. | |
| 291 SCO declares this behavior required for backwards compatibility with 16bit | |
| 292 DOS/Windows environments. The two commands below demonstrate the behavior: | |
| 293 > | |
| 294 echo Hello > file.bat~ | |
| 295 dir > file.bat | |
| 296 < | |
| 297 The result is that the "dir" command updates the "file.bat~" file, instead | |
| 237 | 298 of creating a new "file.bat" file. This same behavior is exhibited in Vim |
| 7 | 299 when editing an existing file named "foo.bat" because the default behavior |
| 300 of Vim is to create a temporary file with a '~' character appended to the | |
| 301 name. When the file is written, it winds up being deleted. | |
| 302 | |
| 303 Solution: Add this command to your _vimrc file: > | |
| 304 :set backupext=.temporary | |
| 305 | |
| 306 Q. How do I change the blink rate of the cursor? | |
| 307 A. You can't! This is a limitation of the NT console. NT 5.0 is reported to | |
| 308 be able to set the blink rate for all console windows at the same time. | |
| 309 | |
| 310 *:!start* | |
| 311 Q. How can I run an external command or program asynchronously? | |
| 312 A. When using :! to run an external command, you can run it with "start": > | |
| 313 :!start winfile.exe<CR> | |
| 314 < Using "start" stops Vim switching to another screen, opening a new console, | |
| 315 or waiting for the program to complete; it indicates that you are running a | |
| 1624 | 316 program that does not affect the files you are editing. Programs begun |
| 7 | 317 with :!start do not get passed Vim's open file handles, which means they do |
| 318 not have to be closed before Vim. | |
| 319 To avoid this special treatment, use ":! start". | |
| 2859 | 320 There are two optional arguments (see the next Q): |
| 3513 | 321 /min the window will be minimized |
| 322 /b no console window will be opened | |
| 3082 | 323 You can use only one of these flags at a time. A second one will be |
| 2859 | 324 treated as the start of the command. |
| 325 | |
| 326 Q. How do I avoid getting a window for programs that I run asynchronously? | |
| 3082 | 327 A. You have two possible solutions depending on what you want: |
| 2908 | 328 1) You may use the /min flag in order to run program in a minimized state |
| 329 with no other changes. It will work equally for console and GUI | |
| 330 applications. | |
| 331 2) You can use the /b flag to run console applications without creating a | |
| 2859 | 332 console window for them (GUI applications are not affected). But you |
| 2908 | 333 should use this flag only if the application you run doesn't require any |
| 334 input. Otherwise it will get an EOF error because its input stream | |
| 3082 | 335 (stdin) would be redirected to \\.\NUL (stdout and stderr too). |
| 2859 | 336 |
| 337 Example for a console application, run Exuberant ctags: > | |
| 338 :!start /min ctags -R . | |
| 339 < When it has finished you should see file named "tags" in your current | |
| 340 directory. You should notice the window title blinking on your taskbar. | |
| 6180 | 341 This is more noticeable for commands that take longer. |
| 2859 | 342 Now delete the "tags" file and run this command: > |
| 343 :!start /b ctags -R . | |
| 344 < You should have the same "tags" file, but this time there will be no | |
| 345 blinking on the taskbar. | |
| 346 Example for a GUI application: > | |
| 347 :!start /min notepad | |
| 348 :!start /b notepad | |
| 349 < The first command runs notepad minimized and the second one runs it | |
| 350 normally. | |
| 7 | 351 |
| 352 Q. I'm using Win32s, and when I try to run an external command like "make", | |
| 237 | 353 Vim doesn't wait for it to finish! Help! |
| 7 | 354 A. The problem is that a 32-bit application (Vim) can't get notification from |
| 237 | 355 Windows that a 16-bit application (your DOS session) has finished. Vim |
| 7 | 356 includes a work-around for this, but you must set up your DOS commands to |
| 237 | 357 run in a window, not full-screen. Unfortunately the default when you |
| 358 install Windows is full-screen. To change this: | |
| 359 1) Start PIF editor (in the Main program group). | |
| 7 | 360 2) Open the file "_DEFAULT.PIF" in your Windows directory. |
| 361 3) Changes the display option from "Full Screen" to "Windowed". | |
| 362 4) Save and exit. | |
| 363 | |
| 364 To test, start Vim and type > | |
| 365 :!dir C:\<CR>". | |
| 366 < You should see a DOS box window appear briefly with the directory listing. | |
| 367 | |
| 237 | 368 Q. I use Vim under Win32s and NT. In NT, I can define the console to default to |
| 369 50 lines, so that I get a 80x50 shell when I ':sh'. Can I do the same in | |
| 7 | 370 W3.1x, or am I stuck with 80x25? |
| 237 | 371 A. Edit SYSTEM.INI and add 'ScreenLines=50' to the [NonWindowsApp] section. DOS |
| 7 | 372 prompts and external DOS commands will now run in a 50-line window. |
| 373 | |
| 6259 | 374 *windows-icon* |
| 375 Q. I don't like the Vim icon, can I change it? | |
| 376 A. Yes, place your favorite icon in bitmaps/vim.ico in a directory of | |
| 377 'runtimepath'. For example ~/vimfiles/bitmaps/vim.ico. | |
