Learning source material for model building implementation?

[fbcosentino]

Hi, I am trying to port this into another language (GDScript). The other language deals differently with file opening, writing, etc, and also implements data types a bit differently (lists and tuples are Arrays). So some adaptations were required during porting.

I have the parser working fine as long as I have the models already build. If I build them in the python version (this repo) and copy the files from the TEMP folder, all works. But if I have the GDScript code trying to build the models, it fails.

I don't have the theoretical knowledge to troubleshoot the model building. Some files mention a coursera course which no longer exists. Is there any material around I could be reading to understand how to build the PCFG model and populate the TEMP dir?
