Comment/Uncomment multiline code blocks with VIM18 February 2013
I did not use VIM for a looong time and forgot nearly everything … feels like learning again from ground up!
For commenting a block of code in VIM, go to the first character of the line, press
Ctrl + v, then select until the last line (e.g.
Shift + g) and press
I + # to insert new or
c + # to replace first character with the hash-symbol on all selected lines.
To uncomment put your cursor on the first hash symbol, press
Ctrl + v, and go down until the last commented line and press
x, which will delete all hash-characters vertically.
Alternatively configure your .vimrc:
vmap ,ic :s/^/#/g<CR>:let @/ = ""<CR> map ,ic :s/^/#/g<CR>:let @/ = ""<CR> vmap ,rc :s/^#//g<CR>:let @/ = ""<CR> map ,rc :s/^#//g<CR>:let @/ = ""<CR>
So you can press
,ic to insert and
,rc to remove comments in normal and visual mode.
