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).

Check out

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
