201 " Instructions for enabling "matchit" support:
|
|
|
202 "
|
|
|
203 " 1. Look for the latest "matchit" plugin at
|
|
|
204 "
|
|
1123
|
205 " http://www.vim.org/scripts/script.php?script_id=39
|
|
530
|
206 "
|
|
|
207 " It is also packaged with Vim, in the $VIMRUNTIME/macros directory.
|
|
|
208 "
|
|
|
209 " 2. Copy "matchit.txt" into a "doc" directory (e.g. $HOME/.vim/doc).
|
|
|
210 "
|
|
|
211 " 3. Copy "matchit.vim" into a "plugin" directory (e.g. $HOME/.vim/plugin).
|
|
|
212 "
|
|
|
213 " 4. Ensure this file (ftplugin/ruby.vim) is installed.
|
|
|
214 "
|
|
|
215 " 5. Ensure you have this line in your $HOME/.vimrc:
|
|
1123
|
216 " filetype plugin on
|
|
530
|
217 "
|
|
|
218 " 6. Restart Vim and create the matchit documentation:
|
|
|
219 "
|
|
1123
|
220 " :helptags ~/.vim/doc
|
|
530
|
221 "
|
|
|
222 " Now you can do ":help matchit", and you should be able to use "%" on Ruby
|
|
1123
|
223 " keywords. Try ":echo b:match_words" to be sure.

1123
|
225 " Thanks to Mark J. Reed for the instructions. See ":help vimrc" for the
