Nesting languages

[schulz]

Hi,

I just stumbled about RSyntaxTextArea recently. We are looking for a Java-component just like that (supporting syntax highlighting, code-templates, auto-completion) for supporting our (proprietary, closed) templating syntax. One issue is that in a template multiple languages get mixed in as well, e.g., HTML, JSP, Javascript, etc. So I wonder, if RSTA supports nesting of languages in some way. I somewhere read that it is highlighting CSS within HTML, would this be CSS syntax included in the HTML scanner or does RSTA somehow switch between the languages?

Thanks,
Stefan

Unfortunately, RSTA cannot delegate between lexers for different languages. File types with lots of "languages," such as PHP (containing HTML, JS, CSS) need to be able to tokenize all "languages" in a single TokenMaker.

Thanks for clarifying. Although, this makes RSTA less comfortable an extension for our purpose.

No worries. I'll be happy to help with any specific problems you have if you choose to build something with RSTA. Just post questions here in the forum, or message me.
