7 *unix* *Unix*
|
|
|
8 This file contains the particularities for the Unix version of Vim.
|
|
|
9
|
|
|
10 For compiling Vim on Unix see "INSTALL" and "Makefile" in the src directory.
|
|
|
11
|
|
|
12 The default help file name is "/usr/local/lib/vim/help.txt"
|
|
|
13 The files "$HOME/.vimrc" and "$HOME/.exrc" are used instead of "s:.vimrc" and
|
|
237
|
14 "s:.exrc". Additionally "/usr/local/etc/vimrc" is used first.
|
|
7
|
15 If "/usr/local/share" exists it is used instead of "/usr/local/lib".
|
|
|
16
|
|
|
17 Temporary files (for filtering) are put in "/tmp". If you want to place them
|
|
|
18 somewhere else, set the environment variable $TMPDIR to the directory you
|
|
|
19 prefer.
|
|
|
20
|
|
|
21 With wildcard expansion you can use '~' (home directory) and '$'
|
|
|
22 (environment variable).
|
|
|
23
|
|
|
24 *fork* *spoon*
|
|
|
25 For executing external commands fork()/exec() is used when possible, otherwise
|
|
|
26 system() is used, which is a bit slower. The output of ":version" includes
|
|
|
27 |+fork| when fork()/exec() is used, |+system()| when system() is used. This
|
|
|
28 can be changed at compile time.
|
|
237
|
29 (For forking of the GUI version see |gui-fork|.)
|
|
7
|
30
|
|
|
31 Because terminal updating under Unix is often slow (e.g. serial line
|
|
|
32 terminal, shell window in suntools), the 'showcmd' and 'ruler' options
|
|
237
|
33 are default off. If you have a fast terminal, try setting them on. You might
|
|
7
|
34 also want to set 'ttyfast'.
|
|
|
35
|
|
|
36 When using Vim in an xterm the mouse clicks can be used by Vim by setting
|
|
237
|
37 'mouse' to "a". If there is access to an X-server gui style copy/paste will
|
|
7
|
38 be used and visual feedback will be provided while dragging with the mouse.
|
|
|
39 If you then still want the xterm copy/paste with the mouse, press the shift
|
|
|
40 key when using the mouse. See |mouse-using|. Visual feedback while dragging
|
|
|
41 can also be achieved via the 'ttymouse' option if your xterm is new enough.
|
|
|
42
|
|
|
43 *terminal-colors*
|
|
|
44 To use colors in Vim you can use the following example (if your terminal
|
|
|
45 supports colors, but "T_Co" is empty or zero): >
|
|
|
46 :set t_me=^[[0;1;36m " normal mode (undoes t_mr and t_md)
|
|
|
47 :set t_mr=^[[0;1;33;44m " reverse (invert) mode
|
|
|
48 :set t_md=^[[1;33;41m " bold mode
|
|
|
49 :set t_se=^[[1;36;40m " standout end
|
|
|
50 :set t_so=^[[1;32;45m " standout mode
|
|
|
51 :set t_ue=^[[0;1;36m " underline end
|
|
|
52 :set t_us=^[[1;32m " underline mode start
|
|
|
53 [the ^[ is an <Esc>, type CTRL-V <Esc> to enter it]
|
|
|
54
|
|
|
55 For real color terminals the ":highlight" command can be used.
|
|
|
56
|
|
231
|
57 The file "tools/vim132" is a shell script that can be used to put Vim in 132
|
|
7
|
58 column mode on a vt100 and lookalikes.
