- *vim_os2.txt* For Vim version 4.6. Last modification: 1997 Feb 17
-
- This file contains the particularities for the OS/2 version of Vim.
-
-
- NOTE
-
- This OS/2 port works well for me and a couple of other OS/2 users; however,
- since I haven't had much feedback, that either means no (OS/2-specific) bugs
- exist (besides the ones mentioned below), or no one has yet created a
- situation in which any bugs are apparent. Report any problems or other
- comments to <paul@murphy.nl> or <paulS@toecompst.nl>. Textmode/notextmode,
- binary mode, and FAT handling all seem to work well, which would seem to be
- the most likely places for trouble.
-
- A known problem is that files opened by Vim are inherited by other programs
- that are started via a shell escape from within Vim. This specifically means
- that Vim won't be able to remove the swap file(s) associated with buffers open
- at the time the other program was started, until the other program is stopped.
- At that time, the swap file may be removed, but if Vim could not do that the
- first time, it won't be removed at all. You'll get warnings that some other
- Vim session may be editing the file when you start Vim up again on that file.
- This can be reproduced with ":!start epm". Now quit Vim, and start Vim again
- with the file that was in the buffer at the time epm was started. I'm working
- on this!
-
- A second problem is that Vim doesn't understand the situation when using it
- when accessing the OS/2 system via the network, e.g. using telnet from a Unix
- system, and then starting Vim. The problem seems to be that OS/2 =sometimes=
- recognizes function / cursor keys, and tries to convert those to the
- corresponding OS/2 codes generated by the "normal" PC keyboard. I've been
- testing a workaround (mapping the OS/2 codes to the correct functions), but so
- far I can't say anything conclusive (this is on Warp 3, by the way). In the
- meantime any help will be appreciated.
-
-
- PREREQUISITES
-
- To run Vim, you need the emx runtime environment (at least rev. 0.9b). This
- is generally available as (ask Archie about it):
-
- emxrt.zip emx runtime package
-
- I've included a copy of emx.dll, which should be copied to one of the
- directories listed in your LIBPATH. Emx is GPL'ed, but the emx.dll library is
- not (read COPYING.EMX to find out what that means to you).
-
- This emx.dll is from the emxfix04.zip package, which unfortunately has a bug,
- eh, I mean a POSIX feature, in select(). Versions of Vim before 3.27 will
- appear to hang when starting (actually, while processing vimrc). Hit return a
- couple of times until Vim starts working if this happens. Next, get an up to
- date version of Vim!
-
-
- HELP AND VIMRC FILE
-
- The VIM environment variable is used to find the location of the help files
- and the system .vimrc. Place an entry such as this in CONFIG.SYS:
-
- SET VIM=c:/local/lib/vim
-
- and copy all the vim_*.txt files and .vimrc to that directory. Vim will then
- be able to find them.
-
- Note: .vimrc may also be called _vimrc to accommodate those who have chosen to
- install OS/2 on a FAT file system. Vim first tries to find .vimrc and if that
- fails, looks for _vimrc in the same place.
-
- If you're using network drives with OS/2, then you can install Vim on a
- network drive (including .vimrc; this is then called the "system" vimrc file),
- and then use a personal copy of .vimrc (the "user" vimrc file). This should be
- located in a directory indicated by the HOME environment variable.
-
-
- ENVIRONMENT VARIABLES IN FILE NAMES
-
- This HOME environment variable is also used when using ~ in file names, so
- ":e ~/textfile" will edit the file "textfile" in the directory referred to by
- HOME. Additionally you can use other environment variables in file names, as
- as ":n $SRC/*.c".
-
- The HOME environment variable is also used to locate the .viminfo file
- (see |viminfo_file|). There is no support yet for .viminfo on FAT file
- systems yet, sorry. You could try the -i startup flag (as in "vim -i
- $HOME/_viminfo") however.
-
- If the HOME environment variable is not set, the value "C:/" is used as a
- default.
-
-
- BACKSLASHES
-
- Using slashes ('/') and backslashes ('\') can be a bit of a problem (see
- vim_dos.txt for more explanation), but in almost all cases Vim does "The Right
- Thing". Vim itself uses backslashes in file names, but will happily accept
- forward slashes if they are entered (in fact, sometimes that works better!).
-
-
- TEMP FILES
-
- Temporary files (for filtering) are put in the first directory in the next
- list that exists and where a file can be created:
- $TMP
- $TEMP
- C:\TMP
- C:\TEMP
- current directory
-
-
- TERMINAL SETTING
-
- Use "os2ansi" as the TERM environment variable (or don't set it at all, as the
- default is the correct value). You can set term to os2ansi in the .vimrc, in
- case you need TERM to be a different value for other applications. The
- problem is that OS/2 ANSI emulation is quite limited (it doesn't have insert /
- delete line, for example).
-
- If you want to use a different value for TERM (because of other programs, for
- example), make sure that the termcap entry for that TERM value has the
- appropriate key mappings. The termcap.dat distributed with emx does not always
- have them. Here are some suitable values to add to the termcap entry of your
- choice; these allow the cursor keys and the named function keys (such as
- pagedown) to work.
