Simple Python-based Static Code Analyzer for C programs based on GLib/GStreamer.
The tool takes advantage of the GObject-Introspection annotations built on top
of GTK-Doc comment blocks. Note that this tool is proof-of-concept only.

To be able to run it, you should install pylangparser first:
    https://github.com/otonchev/pylangparser/wiki

To run it, just type:
    python c_code_analyzer.py

Example:

If run for the following C program:

void b()
{
  GstElement *parent;

  parent = gst_element_get_parent (el);
  do_something_with_pad (pad);

  if (FALSE)
    gst_object_unref (parent);

  gst_element_get_parent (el);
}

the script will output:

INFO: found function definition:
[['void'],
 [['b']],
 [[['GstElement'], [[['*'], ['parent']]]]],
 [[[['parent'], ['='], [['gst_element_get_parent'], [['el']]]]],
  [[['do_something_with_pad'], [['pad']]]],
  [['if'], [['FALSE']], [[['gst_object_unref'], [['parent']]]]],
  [[['gst_element_get_parent'], [['el']]]]]]
