" Vim syntax file for the "papp" file format (_p_erl _app_lication)
"
" Language: papp
" Maintainer: Marc Lehmann <pcg@goof.com>
" Last Change: 2003 May 11
" Filenames: *.papp *.pxml *.pxsl
" URL: http://papp.plan9.de/
" You can set the "papp_include_html" variable so that html will be
" rendered as such inside phtml sections (in case you actually put html
" there - papp does not require that). Also, rendering html tends to keep
" the clutter high on the screen - mixing three languages is difficult
" enough(!). PS: it is also slow.
" pod is, btw, allowed everywhere, which is actually wrong :(
" For version 5.x: Clear all syntax items
" For version 6.x: Quit when a syntax file was already loaded
if version < 600
syntax clear
elseif exists("b:current_syntax")
finish
endif
" source is basically xml, with included html (this is common) and perl bits
if version < 600
so <sfile>:p:h/xml.vim
else
runtime! syntax/xml.vim
endif
unlet b:current_syntax
if exists("papp_include_html")
if version < 600
syn include @PAppHtml <sfile>:p:h/html.vim
