What is your favorite way to comment several lines in Vim?

 

It happens more often than not that I have to comment several lines at once in Vim. Methods that I know are not as fast as say TextMate way to comment lines out.

What is your favorite way to do it?

I currently use:

Method 1:

  • go to first char of a line and use blockwise visual mode (ctrl-v)
  • go down/up until the first characters of every lines you want to comment out are selected
  • use shift-i and then type your comment character ( # for Ruby)
  • use esc to insert the comment character to every line

    • Method 2:

  • select lines you need to comment out using linewise visual mode (shift-v)
  • type : which gives you a :'<,'> prompt which you can extend to :'<,'>s/^/#/

    • Method 3:

  • go to the first line to be commented out
  • make a bookmark for example typing mm
  • go to the last line to be commented out
  • type :'m,.s/^/#/

    • I like method 1 the most but I still hope there is a better way.

    I think you described the most popular ways to comment code, but if you are open to use Vim Scripts, give a look to those:

  • The NERD Commenter
  • EnhCommentify.vim
  • tComment

    • I use a keymap for the regex part, but I do the same visual selection first. Usually using: 

    vip

    to get the visual block (paragraph visual selection)

    then using 

    cc
co

    for comment add/remove (cc,co chosen for muscle memory reasons)

    with the mappings defined in .vimrc as: 

    vmap <leader>cc :s/^/#/<cr>
vmap <leader>co :s/^#//<cr>

    Though this is rather old I just wanted to add my solution which is pretty similar to everyone elses but adds the unhighlighting function. In my .vimrc file I have the following maps: 

    :vmap `c :s/^//*/<cr>gv:s/$/*//<cr>:noh<cr>i
:vmap `r :s/^/*//<cr>gv:s/*/$/<cr>:noh<cr>i

    Note: I use /*line of code*/ style of commenting to be compatible with old c code. In vim I simply highlight the lines and push `c to comment and `r to remove comments.
