You'd need to do a little bit of Vim scripting, but the "synstack" and
"synIDattr" functions are useful for this.
I have the following in one of my vim config files, I've never gotten
around to it because I don't use it very often:
" TODO: support something like the following in a simple function or
command:
" %s/foo/\=(match(map(synstack(line('.'),col('.')),
'synIDattr(v:val, "name")'), '\([Cc]omment\)\|\([sS]tring\)') >= 0 ?
"foo" : "bar")/g
It looks like this command would do a substitute, but only inside
comments and strings. Or only outside. One or the other :-)
