in reply to What is the easy way to comment out chunk of Perl Code

I'm pretty sure there isn't anyway. BUT! If you use vim, there's always vimscripts!

For the vimscript below to work just put it in your .vimrc file. It assumes you have marked a maker 'a' (':mark a' while NOT in insert mode) at the beginning of where you want your un/comment block. Then just scroll down to where you want it to end and type in ',cb#' (while NOT in insert mode) to comment out the block. Alternatively you can type in ',ucb#' to uncomment a block of code.

nmap ,cb# :'a,.s/^/#/gi<CR>:nohl<CR> nmap ,ucb# :'a,.s/^#//g<CR>:nohl<CR>

Since perl doesn't have a standard IDE, i think the answer to this question is largely going to depend on what editor your using for developement.

    I use the BlockComment plugin for vim which I mapped to _c and _C to comment an uncomment respectively.

    It works really well with the highlighting mode that vim uses. For example, go to the start of a block (function, loop, if statement) then hit Shift-V % to highlight the entire block and then _c to comment it out. Or hit Shift-V 20j to highlight the next 20 lines below the cursor, then hit _c to comment or _C to uncomment.

    Oh, and it works for many different languages, not just perl.

    I couldn't get that to work with nmap ,cb#

    But it worked great with map <F8>. Thanks.
