State machines are without any doubt a very good way to model behavior. The new
code generator from Sinelabore translates hierarchical state machines
efficiently into different languages now including Python.
The generator accepts diagrams fr

Given string input such as:

I am going to implement:
- boolean understanding (which operator takes precendence)
- spliting off of attributes into my function which computes their table in the

- piece everything together

Hi all,

Basically, the problem involves doing some nested loops and executing
relatively simple arithmetic code snippets, like:

Code generation should be integrated into a 'master source file' which
