Python API for reading and writing to a raf format used by RIOT's game Leauge of Legends. Developed on Linux, tested on Mac and Windows (for platform's native version of the game). Yeah, I think it's weird too.
Extract all files containing hud string in its path. This will create a new folder extracted wher relevant files will be placed (under their full RAF path):
python rafiki.py extract -s path_to_lol/rads/projects/lol_game_client/filearchives -f "hud/elements" -o extracted
Find all files containing string hud, then search for file overrides in a folder named extracted and if an override exists, replace the file before packing everything back into archives. A new folder overrides will be created where relevant raf archives will be placed. You need to copy these files manually to actually include overrides in the game.
python rafiki.py pack -s path_to_lol/rads/projects/lol_game_client/filearchives -f "hud/elements" -r extracted -o overrides
All above should run ok on Windows. Bear in mind you need to change all "/" to "". Obviously you need to install Python for Windows
You will most likely need a 64 bit version of python (and 64 bit version of Windows) as 32 bit version tends to come up with a Memory Error on writing raf files. Patches welcome
