The script decides whether to search forwards or backwards and chooses
arguments for the |searchpair()| function. Then, the cursor is moved to the
start of the match, and |searchpair()| is called. By default, matching
structures inside strings and comments are ignored. This can be changed by
setting |b:match_skip|.
==============================================================================
2. Activation *matchit-activate*
To use the matchit plugin add this line to your |vimrc|: >
packadd! matchit
The script should start working the next time you start Vim.
To use the matchit plugin after Vim has started, execute this command: >
packadd matchit
(Earlier versions of the script did nothing unless a |buffer-variable| named
|b:match_words| was defined. Even earlier versions contained autocommands
that set this variable for various file types. Now, |b:match_words| is
defined in many of the default |filetype-plugin|s instead.)
For a new language, you can add autocommands to the script or to your vimrc
file, but the recommended method is to add a line such as >
let b:match_words = '\<foo\>:\<bar\>'
to the |filetype-plugin| for your language. See |b:match_words| below for how
this variable is interpreted.
TROUBLESHOOTING *matchit-troubleshoot*
The script should work in most installations of Vim. It may not work if Vim
was compiled with a minimal feature set, for example if the |+syntax| option
was not enabled. If your Vim has support for syntax compiled in, but you do
not have |syntax| highlighting turned on, matchit.vim should work, but it may
fail to skip matching groups in comments and strings. If the |filetype|
mechanism is turned off, the |b:match_words| variable will probably not be
defined automatically.
2.1 Temporarily disable the matchit plugin *matchit-disable* *:MatchDisable*
To temporarily disable the matchit plugin, after it hat been loaded,
execute this command: >
:MatchDisable
This will delete all the defined key mappings to the Vim default.
Now the "%" command will work like before loading the plugin |%|
2.2 Re-enable the matchit plugin *:MatchEnable*
To re-enable the plugin, after it was disabled, use the following command: >
:MatchEnable
This will resetup the key mappings.
==============================================================================
3. Configuration *matchit-configure*
There are several variables that govern the behavior of matchit.vim. Note
that these are variables local to the buffer, not options, so use |:let| to
define them, not |:set|. Some of these variables have values that matter; for
others, it only matters whether the variable has been defined. All of these
can be defined in the |filetype-plugin| or autocommand that defines
|b:match_words| or "on the fly."
The main variable is |b:match_words|. It is described in the section below on
supporting a new language.
*MatchError* *matchit-hl* *matchit-highlight*
MatchError is the highlight group for error messages from the script. By
default, it is linked to WarningMsg. If you do not want to be bothered by
error messages, you can define this to be something invisible. For example,
if you use the GUI version of Vim and your command line is normally white, you
can do >
:hi MatchError guifg=white guibg=white
<
*b:match_ignorecase*
If you >
:let b:match_ignorecase = 1
then matchit.vim acts as if 'ignorecase' is set: for example, "end" and "END"
are equivalent. If you >
:let b:match_ignorecase = 0
then matchit.vim treats "end" and "END" differently. (There will be no
b:match_infercase option unless someone requests it.)
*b:match_debug*
Define b:match_debug if you want debugging information to be saved. See
|matchit-debug|, below.
*b:match_skip*
If b:match_skip is defined, it is passed as the skip argument to
|searchpair()|. This controls when matching structures are skipped, or
ignored. By default, they are ignored inside comments and strings, as
determined by the |syntax|
