Help Wanted

[Ramneek Handa]

Hi all,
  I have a task in hand for which i am required to reverse engineer c++
header files. Following is briefly what is required:
1. To find out various classes in the header.
2. To find out the various member functions inside each class.
3. To find out the parent class of each class(inherited from).
4. To find out various parameters for each function.

in short all the meta informaton :)..

i have following queries:

1) Is is good to generate a parse tree of the header file and evaluate
the various reqd things?
2) I have Roskind grammar, is it good enuf?
3) How fast is bison and flex combo, How much time wud it take to
generate a parse tree of a 100kb file?
4) Is there any other way to do this without making the parse tree?
5) Do i need the whole grammar for this purpose or can i use some
subset? if yes where can i find it :) ?

thanx in advance
-WT

Aside from
  %token <ID> IDENTIFIER
you also need
  %type <ID> myrule

then you can have

myrule
: IDENTIFIER
| SOMETHING_TO_IGNORE IDENTIFIER
  {
    $$ = $2;
  }
;
