Question

I do all my coding in vim and am quite happy with it (so, please, no ‘use a different editor’ responses), but have an ongoing annoyance in that the smartindent feature wants to not indent comments beginning with # at all. e.g., I want

  # Do something   $x = $x + 1;   if ($y) {     # Do something else     $y = $y + $z;   } 

instead of vim’s preferred

# Do something   $x = $x + 1;   if ($y) { # Do something else     $y = $y + $z;   } 

The only ways I have been able to prevent comments from being sent to the start of the line are to either insert and delete a character on the line before hitting # (a nuisance to have to remember to do every time) or turn off smartindent entirely (losing automatic indentation increase/decrease as I open/close braces).

How can I set vim to maintain my indentation for comments instead of sending them to the start of the line?

Answer 1

It looks like you’re coding in Perl. Ensure that the following are set in your .vimrc:

filetype plugin indent on syntax enable 

These will tell Vim to set the filetype when opening a buffer and configure the indentation and syntax highlighting. No need to explicitly set smartindent since Vim’s included Perl syntax file will set it (and any other Perl-specific customizations) automatically.

Note: having either set smartindent and/or set autoindent in ~/.vimrc may prevent the solution from working. If you’re having problems, look for them.
