This is great, although very limited in the sense that it "makes
sense" only for latex keywords. What I mean is this:
If there is a line break or a '}' in the _text_ then the font
style/color specification breaks down. And you don't expect either of
these in the keywords ;) I guess the styling/coloring works like sed -
one line at a time.
Example:
With the following definition in syntax-patterns.txt:
red Y \\textcolor\s*\{red\}\s*\{[^}]*\}
The following works:
\textcolor{red}{This is in red}
But the following two don't:
(1)
\textcolor{red}{This should have been (line break here)
in red}
(2)
\textcolor{red}{This also should have been in red: $\{a,b\}$}
I think these situations are too common and unfortunately cannot be
handled by regex. Hence the usage is very limited.
