wanted: C++ parser written in Python

[Franz Steinhaeusler]

Hello NG,

has anyone written such a thing in python?
Where could I look for?

(I need it for an editor written in wxPython to display function names,
include, global variables, classes, ... in a sidepanel).

kind regards,

Try ANTLR with python code generation:
http://www.antlr.org/

And C++ grammers:
http://www.antlr.org/grammar/cpp

You can generate a c++ parser in python with the above.

^^^^^^^^^^^^^^^^^
Sorry. Haven't look into the stuff carefully.
That grammer file requires some c++ code.

Thank you, but it is too big.

Anyway:
I'm looking for some (simple) "rules" to parse (regex)
and try to implement myself, if nothing is available.

It don't have to be perfect.

Maybe I look for some code in for example
Dev-Cpp from Bloodshed (there is also a c++ class browser).

Before you start implementing one yourself. Regexp solution would
probably be a bit flakier. And do share your results when you get
some; I'm in need of a c++ parser myself.

Thank you for this information!

Also a little to complicated, I'm looking for
a quick solution.

I don't want to scan a whole project,
only the currently open file.

class definition
method/function
ignore comment lines
show #includes would be enough at first.


I will inform again

In the "instant gratification" department, there is Emacs with the
Emacs Code Browser interface. ECB contains a C++ parser done in
Lisp. If you need to extract things, there is a PyMacs interface that
works quite well.
See http://www.emacswiki.org for details.
Given the "power, performance, ease of use; pick any two" cliché,
we're clearly ditching the middle one with this approach.
Best,
Chris

You can look at the techniques and regular expressions in the
testgen.c.unit test module that is part of a generic test framework
called TestGen. TestGen uses a parser to automatically stub / copy
functions for testing purposes. The parser is capable of identifying
the function/method name as well as the parameters and return type.
The only caveat with using regular expressions is the function/method's
closing } must be in column zero. If you figure out a different way to
get around the restriction or other improvements to the parser let me
know.

I'm about to release a newer version, but the area that you would be
looking at is not changing so I would go ahead and download the latest
that is there. TestGen can be found at
sourceforge.net/projects/testgen

I've written something simple in python. you can try it.

hope it helps.
