[CEDET-devel] Implementing context functions

[Dan D. (s. <da...@ma...>]

Hi,

I'm working on a new wisent grammar for Erlang -- I realise there's a
bovine grammar; I'm re-writing for wisent and adding full context and
completion support. The grammar is complete and parses every file I
throw at it, but I'm having trouble with the context-related overload
functions. Can you give me some ideas on how you would implement, say,
semantic-get-local-variables? 

I have tried building a tree of scopes as I parse, but that would
require me to re-parse the entire file in order to obtain context at
point. Maybe the tag cache makes this OK; I'm not sure. I also tried
storing the context in the region's semantic overlay, but lack of
parent-child relationships between overlays makes it hard to implement
things like semantic-up-context.

I'm out of ideas. Can you give me some advice?

Thanks,

-Dan Debertin
