SCXML to ANSI-C converter for transforming state charts into efficient C code written entirely in Python. It is designed to work with UML-State-Machine-in-C, which serves as a lightweight state machine framework with the scxml_to_c generating the scaffolding for a specific state machine implementation.
The project was started in response to an embedded switch/case based state machine that, over the course of 5 years of feature creep-morphed into a 2000+ loc monster. It has the following ethos:
- Written in 100% Python.
- Transform into simple, efficient, and easy to read C code.
- Pip install-able with minimal dependencies (lxml, csnake)
- Be flexible enough for programmed to do everything they need in embedded applications
pip install scxml_to_c
> scxml -s <path to scxml_to_c file> -o <name of output files> -d <directory for output files>
The output name and directory are optional arguments. If you leave out both, the tool will use the scxml filename to generate the name of the .c and .h files and will output them to the current directory. For example, the following command will generate awesome.h and awesome.c in the current directory.
~/develop/awesome_project/src$ scxml_to_c -s awesome.scxml
