Critical reading VICE

This is the repository of the scripts that were used in helping in an attempt of critically reading the VICE[^1] source code.

VICE is a program that runs on a Unix, MS-DOS, Win32, OS/2, BeOS, QNX 4.x, QNX 6.x, Amiga, Syllable or Mac OS X machine and executes programs intended for the old 8-bit computers.

More information on this analysis can be found under https://phd.thgie.ch/notes/VICE.html.

Setup

  1. Download the source distribution from https://vice-emu.sourceforge.io/index.html#download
  2. Copy all files ending in *.c and *.h from the downloaded archive's src folder to this repository's src folder
  3. Flatten the hierarchy in the repository's src folder; no subfolders!
  4. You are now able to execute the python scripts

Scripts

  • count.py counts the total lines of code in all the files
  • split.py splits the provided source code files into files with either just comments or just code, and moves them to the appropriate folders
  • vice-network.py generates a CSV file with the relations between files and their authors; meant to be imported in Gephi after
  • authors-network.py generates a CSV file with the relations between files according to their #include statements; to be imported in Gephi after
