A practical and educational implementation of CPP14 source code CFG extractor, implemented using Python3 and Antlr4.
A Control Flow Graph (CFG) is the graphical representation of control flow or computation during the execution of programs or applications. Control flow graphs are mostly used in static analysis as well as compiler applications, as they can accurately represent the flow inside a program unit. The control flow graph was originally developed by Frances E. Allen.
The program have been implemented and tested using python3.8, though, it would be ok with other minor python3 versions (3.x).
Install Antlr4 how it described in the following link.
By running the src/cfg_from_stdin.py a prompt will be shown
in terminal asking for the source code path.
