pyglreg: OpenGL XML API Registry Parser

glreg provides functionality to parse and extract data from OpenGL XML API Registry files. Types, enums and functions (commands) in the registry can be enumerated and inspected. This module also provides functions to resolve dependencies and filter APIs in the registry. This makes it useful for generating OpenGL headers and loaders.

Sample code

Import the module:

>>> import glreg

Load a Registry object from a file:

>>> registry = glreg.load(open('gl.xml'))

Generate a simple OpenGL ES 2 C header:

>>> for api in glreg.group_apis(registry, api='gles2', support='gles2'):
...     print('#ifndef ' + api.name)
...     print('#define ' + api.name)
...     print(api.text)
...     print('#endif')
#ifndef GL_ES_VERSION_2_0
#define GL_ES_VERSION_2_0
#include <KHR/khrplatform.h>
typedef khronos_int8_t GLbyte;...
