Vim:Commenting Blocks of Code
From Zoelife4U Wiki
One of the things that irritates me about IDEs is having to command blocks of code one line at a time. Now, Vim offers relief from this. So vim ~/.vimrc and slap the following in there towards the bottom.
" lhs comments map ,# :s/^/#/<CR> <Esc>:nohlsearch <CR> map ,/ :s/^/\/\//<CR> <Esc>:nohlsearch <CR> map ,> :s/^/> /<CR> <Esc>:nohlsearch<CR> map ," :s/^/\"/<CR> <Esc>:nohlsearch<CR> map ,% :s/^/%/<CR> <Esc>:nohlsearch<CR> map ,! :s/^/!/<CR> <Esc>:nohlsearch<CR> map ,; :s/^/;/<CR> <Esc>:nohlsearch<CR> map ,- :s/^/--/<CR> <Esc>:nohlsearch<CR> map ,c :s/^\/\/\\|^--\\|^> \\|^[#"%!;]//<CR> <Esc>:nohlsearch<CR> " wrapping comments map ,* :s/^\(.*\)$/\/\* \1 \*\//<CR> <Esc>:nohlsearch<CR> map ,( :s/^\(.*\)$/\(\* \1 \*\)/<CR><Esc>:nohlsearch <CR> map ,< :s/^\(.*\)$/<!-- \1 -->/<CR> <Esc>:nohlsearch<CR> map ,d :s/^\([/(]\*\\|<!--\) \(.*\) \(\*[/)]\\|-->\)$/\2/<CR> <Esc>:nohlsearch<CR>
To use just use the comma and the left character that begins the comment:
,#
Here's the list of comments to languages:
,# shell, perl, etc
,/ c++
,> email quote
," vim
,% latex, prolog
,! assembly?... add single !
,; scheme
,- SQL add --
,c clears any of the previous comments
