Add functionality missing from the python libclang bindings

Cymbal

Overview

Cymbal makes it easy to add functionality missing from libclang Python bindings

The Clang libclang python bindings use ctypes to invoke functions present in libclang dynamic library. In some cases, only a subset of the C functions are available, because the platform or version specific Python bindings omit functions. Cymbal simplfies the process of dynamically adding those methods to Types and Cursors.

Usage

Import Cymbal, monkeypatch any required functions, adding appropriate ctypes annotations as necessary.

import clang.cindex
from clang.cindex import *
import cymbal
from ctypes import *

# add functions omitted from the pip installable clang packages on OSX

cymbal.monkeypatch_type('get_template_argument_type',
                        'clang_Type_getTemplateArgumentAsType',
                        [Type, c_uint],
                        Type)

cymbal.monkeypatch_type('get_num_template_arguments',
                        'clang_Type_getNumTemplateArguments',
                        [Type],
                        c_int)

Requirements

The only requirements are libclang and the python bindings for libclang.
