Is it possible to create plugins/snippits that would support two types of code in one file.

In my specific example, I want to do some literate programming using noweb: the file would be a mix of Latex and C++. The question would then be, can you tell Sublime that this extent of text should use Latex specifications and that extent of text should C++ specifications (as delimited by noweb)?

Would I have to merge say the Latex specification w/ the C++ specification w/ some noweb tossed into the mix?

I did see the bit on using sweave/R with TextMate, but that seems sweave specific.

Any hints, pointers tips appreciated.

In your tmLanguage file, you can refer to other grammars. For example, the HTML file references the Javascript file. I’d recommend looking at how that’s done.
