Fanuc's Karel robot programming language limits variable names length to 12 characters. This is annoying when writing long programs.
This small python script takes a .kl karel file as input and parses it.
The variable names are then shortened in a deterministic way via a hash function. The line numbers are also preserved.
In a terminal in the downloaded repo folder, type :
python preprocessor.py -i INPUT_FILE.kl -o OUTPUT_FILE.klYou can then use ktrans.exe on the output file to get your compiled .pc file.
Although used extensively during months on an actual Fanuc robot, this script could still create bugs in your Karel programs that could result in unexpected robot behaviour. Always check the generated code before loading it on an actual robot. We offer no warranty regarding the validity of the generated code, and disclaim liability for any damages resulting from its use.

It would be nice to add more advanced preprocessing, and even basic syntax checking, to make error messages more explicit than with ktrans.exe.
I would also be more prudent to build a test suite.
