make cc real-time parse

[blueshake]

optimize the cc search process based on real-time parse.

before:

parse the contexts between the begin and the caret position to get the function tokens.


now

get the function tokens from the tokentree with filename directly based on real-time parse.and this reduce the parse time.

enjoy it.

hi,morten :
you are right.so the patch above should be changed.

[blueshake]

This is certainly the cause for the wrong file being returned which I've reported here:
http://forums.codeblocks.org/index.php/topic,11800.msg80076.html#msg80076
Look: Previously the parser was created based on the native parsers current state. Now you just use the attached parser which maybe wrong because it may point to the wrong file!
I believe something like FindParserFromEditor needs to be used here...

I check out the FindParserFromEditor.It just simply return the m_Parser.

I check out the FindParserFromEditor.It just simply return the m_Parser.

You are right. What a messy code that was... From the early stages where there were several parsers per project. I've cleaned it up thoroughly and committed.

Ps.: While I was at it I fixed the bug with the wrong file pointer... ;-)
