Hi, A C++ compiler sure manages to parse the C++ language but I wonder if there is a free and simple to use C++ parser (which does not need to handle the full grammar or check the syntax of the C++ language) that is able to extract the major C++ artifacts like classes, functions etc. Thanks in advance! /Tom [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

First there are open source compilers, such as GNU. If what you really want it automatic generation of documentation, see http://www.doxygen.org. Even if it does not do exactly what you want, you might be able to use it for parsing and add your own program for post processing to get exactly what you want. -- Jack Klein Home: http://JK-Technology.Com FAQs for comp.lang.c http://www.eskimo.com/~scs/C-faq/top.html comp.lang.c++ http://www.parashift.com/c++-faq-lite/ alt.comp.lang.learn.c-c++ http://www.contrib.andrew.cmu.edu/~ajo/docs/FAQ-acllc.html [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

Consider (typical example of the "most vexing parse"): a b(c); This can be either a variable definition: int myVar( EOF_or_any_predefined_constant ); or the (forward) declaration of a function: int myFunction( int_or_any_predefined_type ); One also has to take care of preprocessor macros... Other than in free compilers, you will also find code parsers in tools such as the excellent doxygen ([url]www.doxygen.org)[/url], written by Dimitri van Heesch (and supported quite well). You could also let doxygen generate an xml-based description of the code, which might contain all the information you need. Commercial parsing solutions also exist...

The "PUMA" library which is the base of "Aspect C++" <http://www.aspectc.org/> has to be capable of parsing large parts of C++. Maybe this helps you.
