grammar scope: Embedded (inline) code

[wion]

There is a problem with the existing grammar scope for inline code (i.e. @code@). For the most part it works, but it you happen to use something like follows:

". . . some para text, with a @1@, and some more text, and then a @3@, and some more text . . ."

The regular expression reads the two instances of code as a single instance wrapped by the outer most ampersands...

". . . some para text, with a @1@, and some more text, and then a @3@, and some more text . . ."

This only happens if the single characters are integers, like if indicating attribute values, or whatever.

This regex seems to work better in the grammar: ((?=@)\S.+?\S(?<=@)). It eliminates the faulty capture across two instances of embedded code having single digits.

The associated grammar entry:

{	name = 'markup.code.textile';
	match = '((?=@)\S.+?\S(?<=@))';
},

The only problem noticed so far is in the rare case you might be writing about regular expressions and use a Textile code example like this, @\s(@(\S.+?\S|\S)@)\s@, it will appear captured like this: @\s(@(\S.+?\S|\S)@)\s@.

What are the odds of you ever writing about regular expressions?
