File this in the 'oldie-but-goodie' category... I've had this on my
(too-long) todo list since I first saw it. As you probably discovered,
it's very easy *if* you don't care about the opening XML tag being
highlighted as XML. But here's what I came up with to get it working.
The first portion follows the general pattern for including other
syntax.
""" ~/.vim/syntax/jelly.vim
""" also attached as jelly.vim in case the group mangles the long line
function! s:NoCurrent()
if exists("b:current_syntax")
unlet b:current_syntax
endif
endfunction
" include XML syntax
runtime! syntax/xml.vim
call s:NoCurrent()
" include SQL syntax w/ ability to include it elsewhere
syntax include @sql syntax/sql.vim
call s:NoCurrent()
let b:current_syntax='jelly'
""" here's the tricky part:
syn match sqlCode
+\%(<\(sql:\w\+\)\%(\_s\_[^>]*\)\{-}>\_s*\%[<!\[CDATA\[]\)\@<=\_.\{-}\%(\%(\]\]>\)\{-}\_s*<\/\1\)\...@=+
contai...@sql
syn cluster xmlRegionHook add=sqlCode
Three things that help it work:
1. It uses a 'match', rather than a 'region'. (I couldn't get regions
to "play nice" with the other XML regions -- and especially with
matchgroups, it seems impossible to get the highlighting right.)
2. It does NOT include the final closing '>' of the closing tag.
(Otherwise, the normal XML highlighting is seen as matching sooner,
since this pattern is using the lookbehind to match the start tag. (I
think...))
3. It uses lookbehind and lookahead (\@<= and \...@=) rather than start and
end (\zs and \ze). Using those prevents the xmlStart- and -EndTags from
working properly.
I used the test.jelly file attached for testing. All of the
sql:-namespaced nodes show up right for me. (The SQL looks SQL-ish.)
While the other three nodes look like normal XML.
This was a fun one, even though I suspect you already worked around it
somehow.
