C++ Name Mangling Library for Python [closed]

Question

I'd like to mangle and demangle C++ function names in a Python program. Is there anything like that available? I searched for hours now, perhaps I'm lucky here...

Answer 1

If you want to demangle names, eg. for display, then you can create a pipe that runs c++filt.

def demangle(names):
    args = ['c++filt']
    args.extend(names)
    pipe = subprocess.Popen(args, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
    stdout, _ = pipe.communicate()
    demangled = stdout.split("\n")

    # Each line ends with a newline, so the final entry of the split output
    # will always be ''.
    assert len(demangled) == len(names)+1
    return demangled[:-1]

print demangle(['_ZNSt15basic_stringbufIcSt11char_traitsIcESaIcEE17_M_stringbuf_initESt13_Ios_Openmode',
    '_ZNSt15basic_stringbufIcSt11char_traitsIcESaIcEE6setbufEPci'])

You can specify arguments to c++filt if you need to use a specific demangling method.

Mangling a name is much harder, and probably can't be done without knowing the definitions of the types involved.
