I was fiddling around with the errorformat and makeprg opts, and as I code in different languages, i was wondering if there was a way of specifiing a special makeprg and errorformat parameter for each language, and there is! just edit the $VIM/ftplugin/[syntaxfile].vim

For example, perl.vim, added at the end:
 set makeprg=$HOME/bin/vimparse.pl\ -c\ %\ $*
 set errorformat=%f:%l:%m

c.vim
 set makeprg=g++\ %

It works delightfully with the :Make tip [[VimTip203]]

I mapped F-5 to :Make, and made it go back to the main window:
 map <F5> :Make<CR><C-w><Up>

I prefer to make a compiler plugin, then use a ftplugin to set a default compiler, i.e.:
<pre>
~/.vim/compiler/xmllint.vim:
if exists("current_compiler")
  finish
endif
let current_compiler = "xmllint"
setlocal makeprg=xmllint\ --valid\ --noout\ %
setlocal errorformat=%f:%l:\ %m
</pre>
<pre>
~/.vim/ftplugin/xml.vim
compiler xmllint
</pre>

This way you can actually set up as many compilers as you want for the same filetype. I set a default in my ftplugin, but then a quick ':compiler somecompiler' will change to a different one as opposed to having to set makeprg and errorformat (remembering those is non-trivial)
