Annotate the type of the arguments and return type of function calls.

This is a modification of the python interpreter that will log the argument types and the return type of all function calls.

These modifications are released under the MIT. See LICENSE.

The code is organized as follows:

• extra: has the main routines to get the types and log them.
• test_annotations/: folder with the test for this wrapper.
• patches/Makefile.pre.in.patch: changes to the compile process.
• patches/python.c.patch: added the call to initialize the annotator.
• patches/ceval.c.patch: added the necessary calls to log the types before a call.
• build.sh: script that downloads the sources, applies the patches and compiles the sources.
• run.sh: script to run the included tests, python's regression suite, and numpy's tests. It will generate a file called python2_annotations.tsv.
• remove_multiple.py: script to remove those lines for which the call signature is duplicated. For example: if we have f(int)-> str and f(int)-> int, then this script will remove those lines.
