*comment.txt* For Vim version 9.1. Last change: 2024 Jun 04
VIM REFERENCE MANUAL
Commenting and un-commenting text.
==============================================================================
See |comment-install| on how to activate this package.
The comment.vim package, allows to toggle comments for a single line, a range
of lines or a selected text object. It defines the following mappings:
*gcc*
gcc to comment/uncomment current line
*o_gc*
gc{motion} to toggle comments for the selected motion
*gcip*
gcip to comment/uncomment current paragraph
*gcG*
gcG to comment/uncomment from current line till the end of a buffer
*v_gc*
{Visual}gc to comment/uncomment the highlighted lines.
This plugin uses the buffer-local 'commentstring' option value to add or remove
comment markers to the selected lines. Whether it will comment or un-comment
depends on the first line of the range of lines to act upon. When it matches
a comment marker, the line will be un-commented, if it doesn't, the line will
be commented out. Blank and empty lines are ignored.
The comment marker will always be padded with blanks whether or not the
'commentstring' value contains whitespace around "%s".
If the mapping does not seem to work (or uses wrong comment markers), it might
be because of several reasons:
- the filetype is not detected by Vim, see |new-filetype|,
- filetype plugins are not enabled, see |:filetype-plugin-on| or
- the filetype plugin does not set the (correct) 'commentstring' option.
You can simply configure this using the following autocommand (e.g. for legacy
Vim script): >
autocmd Filetype vim :setlocal commentstring="%s
This example sets the " as start of a comment for legacy Vim Script. For Vim9
script, you would instead use the "#" char: >
autocmd Filetype vim :setlocal commentstring=#\ %s
==============================================================================
Options:
*g:comment_first_col*
*b:comment_first_col*
By default comment chars are added in front of the line, i.e. if the line
was indented, commented line would stay indented as well.
However some filetypes require a comment char on the first column, use this option
to change default behaviour.
Use g:comment_first_col to change it globally or b:comment_first_col to
target specific filetype(s).
