CatSh is a custom language that gets converted to a scratch .sb3 file.

What you'll need:

• python
• wave python module

Running:

• open a shell
• navigate to the folder where the python compilation script is located
• run python main.py convert {path to .catsh file}
• import the output.sb3 file into scratch and enjoy!
• NOTE: there may be some duplicate blocks when importing. that is not done by the converter instead is done by scratch. if you know a fix, please let me know.

Changelog:

Version 1.0:

• added the compiler
