I am presuming that you are running VIM. There are very good sources of information about configuring VIM already so check these out.

http://vim.sourceforge.net/
http://www.vim.org/
http://groups.yahoo.com/group/vim/

That last one contains the archive of the VIM-users mailing list and will tell you how to join. That is the best place to ask this question.

VIM already has decent Perl high-lighting capabilities (try ':syn on' while editing a .pl or .pm file). One more note of interest though - one of the VIM developers recently updated a super-charged Perl syntax high-lighting script on VIMonline. Check the script archives there.

Update: Now that I've pondered a bit what I told you here and what you are actually asking, perhaps you should also check out what perltidy has to offer...

Update 2: I consider this question to be sufficiently Perl related to remain on this site. It appears to deal with utilities for formatting and displaying Perl code. While it is better classified as a discussion, I do feel it adds useful (if only marginally so) discussion to the site.

Good luck (and ask a Perl question, next time! {G}),
