bytebraise

This project is a proof-of-concept experiment to see how much of BitBake can be implemented in Rust.

Status

This is very early code and still somewhat a testbed for ideas.

What is implemented

• Lexer and parser for the BitBake language, backed by Rowan
• Partial re-implementation of DataSmart
  • Notably lacking: caching, variable history, and the new : override syntax
• Proof-of-concept Python support - enable with the python feature when building
  • See for example: https://github.com/Agilent/bytebraise/blob/main/src/data_smart/variable_parse.rs

FAQ

Q: Do you intend to replace BitBake?
A: Definitely not.

Q: Then why build this?
A: Mostly just to see if it's possible and as an exercise to learn Rust. I also wanted a deeper understanding of BitBake, and what better way to get that than by reimplementing it?

Q: What could it be used for?
A: Right now, not much. Eventually, it could be useful for linters and formatters. What's especially nice about Rust is that you can build statically-linked executables and thus avoid the nightmare of distributing Python applications. Do however note that it's not currently feasible to statically-link applications using bytebraise's optional python support, due to this issue.
