Tip #473: "compiler" for perl

At on stage I was writing a lot of perl scripts/modules with Vim and found it useful to be able
to run the perl syntax-checker (perl -c) from within Vim via the "make" function. To be able
to do this you'll need to add the following Module (VimCompile.pm) to your @INC
---------------<cut here>---------------
#!/usr/bin/perl -w
#$Id: VimCompile.pm,v 1.2 2002/02/16 01:07:03 forkin Exp $
# reformat "perl -c" syntax-check error-/warning-messages for Vim
package VimCompile;

use strict;

sub _die {
    my ($msg)=@_;
    $msg=~s/^((.* at )((.*) line )([0-9]+)(\.|, near .*))$/$4:$5: $1/mg;
    die qq/$msg/;
}
sub _warn {
    my ($msg)=@_;
    $msg=~s/^((.* at )((.*) line )([0-9]+)(\.|, near .*))$/$4:$5: $1/mg;
    warn qq/$msg/;
}
$SIG{'__DIE__'}=\&_die;
$SIG{'__WARN__'}=\&_warn;
# return OK
1;
__END__
------------<cut here>---------------
This Module will reformat the warnings/errors so that Vim can parse them (to allow you to
jump to the location/source-code of the error). You will also need to deposit the following
(perl.vim) in your ~/.vim/runtime/compiler directory.
------------<cut here>---------------
" Vim compiler file
" Compiler:     perl (output of "die" massaged)

if exists("current_compiler")
  finish
endif
let current_compiler = "perl"

" A workable errorformat for "perl -c"
setlocal errorformat=%f:%l:\ %m

" default make
setlocal makeprg=perl\ -MVimCompile\ -c\ %
