Add support for yocto project files

[brightchuh]

Dear OpenGrok Developers,

Could you please add support for yocto project files, such as .bb, .bbapend, .bbclass etc. Nowadays yocto project is getting more and more popular for embedded linux. Currently yocto project files are rendering as plain text, without syntax highlighting. It's not very convenient.

Hello,
what are the pointers to the files? What is their BNF or some lexical or at least regexp parser?
Also are they supported by jflex? If not, can you write a regexp to get some basic semantical parsing for those files?

The analyzers themselves are not that hard, it's just lexical parser and semantics comes from jflex. If you have a look in git log history for some other parsers, you will see it's easy to write one (even with regexps for jflex).

Since if you know yocto, then you might be the best person to write it, we will gladly assist with pointers how stuff is done (but git history is the best start).

What do you think? Care to give it a try? (could be nice weekend project)

I'm not familiar with java or web stuffs. But I'll try to look into this. Thanks a lot!

Java is not that hard to learn(I think there is even learn java in 16 days book) and learning how analyzer works (or lexer and simple semantic analysis) is fun. Give it a whirl, you'll like it.
