VIM syntax highlighting: Use of AWK syntax inside shell scripts
I've been trying to add a simple script inside ~/.vim/after/syntax/sh.vim that will use the syntax highlighting for awk when the user does something like
Code:
#! /bin/sh
awk < myfile.txt "
BEGIN {i=0}
/stupid/ {$3 = ''; print; i = i + 1}
END {print \"I found\", i, \"stupid people\"}
"
There are facilities to do this, of course, but I'm stumbling over the precise details. Here's what I have so far:
Code:
if exists('b:current_syntax')
" Unset this, or the AWK syntax file thinks it's already loaded!
let s:current_syntax = b:current_syntax
unlet b:current_syntax
endif
syntax include @AwkSyntax syntax/awk.vim
if exists('s:current_syntax')
" Undo what we did before
let b:current_syntax=s:current_syntax
else
unlet b:current_syntax
endif
syntax region AwkScript start=#\(^\s*g\=awk\(\s\+\p\+\)*\s\+\)\@<='#
\ end=#'# contains=@AwkSyntax matchgroup=SpecialComment
syntax region AwkScript end=#"# skip=#\\"#
\ start=#\(^\s*g\=awk\(\s\+\p\+\)*\s\+\)\@<="#
\ matchgroup=SpecialComment contains=@AwkSyntax
This works for the single-quote version, but not the double-quote version (it recognizes everything as an AWK string). I don't know how to resolve this issue. What it should do is start AWK syntax right AFTER the quotation mark (not ON it...) and avoid recognizing the entire string as a shell string. I can't seem to do both of these things at the same time. |
