Quickly gather insights into a cython compiled executable/shared library. Cython2Skeleton reconstructs the class/functions names with simple techniques of reverse engineering. The scripts takes a cython compiled file (.elf, .so) as input and reconstructs the original class and function names from the python file. Adds as much information as possible into the produced python file, such as docstrings and comments.

To run the script, simply run for a single file:

python src/cython2skeleton.py --filepath=/tmp/api.so run_and_store --target_filepath=/tmp/api.so.skel --print_unknown=True --store_all_strings=True 

To run the script over a directory recursively:

python src/helper.py --src_dir=/tmp/src_dir --target_dir=/tmp/target_dir --searched_file_extensions=so,elf --print_unknown=True  --store_all_strings=False

If to many irrelevant strings are printed, the parameters only_interesting: bool and min_chars: int can be used to adjust the results.
