This repo consists of a set of tiny scripts for Warcraft 3 game history visualization. The supported graphs include:
The underlying library used for replay parsing was the w3g lib by Anthony Scopatz.
This is one of the very few w3g python libraries out there and it's written in a very clean and simple manner.
However, at the point of creation of this project the library had been abandoned by its maintainer and it was crashing on newer replays.
I did rewrite the engine so it could handle the latest version of replays.
The second issue was the performance: as clean as the code has been, the library was literally unsuitable for use on large samples of data, - each replay file could take up to 3-5 seconds to parse.
As the internal parsing engine has been slightly optimised, the whole pack of ~900 replays took just about 4.5 seconds to get parsed in total.
Which means we got close to (10^3)x running time speedup on a ~10^3 items sample with just a handful of simple optimizations in a totally unknown codebase in a couple of hours. Oh, and by the way, it was my first time working with Python.
