Question

I am looking for a Windows based library which can be used for parsing a bunch of C files to list global and local variables. The global and local variables may be declared using typedef. The output (i.e. list of global and local variables) can then be used for post processing (e.g. replacing the variable names with a new name).

Is such a library available?

Answer 1

Some of the methods available:

• Elsa: The Elkhound-based C/C++ Parser
• CIL – Infrastructure for C Program Analysis and Transformation
• Sparse – a Semantic Parser for C
• clang: a C language family frontend for LLVM
• pycparser: C parser and AST generator written in Python

Alternately you could write your own using lex and yacc (or their kin- flex and bison) using a public lex specification and a yacc grammar.
