# generate a sample config (you'll want to modify it) There are some wonderful instructions provided here:īriefly, here’s how to set up and use the tool: independent tooling setup (doesn’t rely on an existing package manager).Tools like pre-commit are especially relevant to firmware repositories: sometimes enthusiasm for development tooling can be low (creates a need for.tooling can be difficult to set up (especially across Linux/Windows/Mac hosts).often multiple programming languages used (C/C++, Rust, Python, bash,.ad-hoc or large variety of build systems/packaging approaches (no standard.Other popular languages/frameworks have de-facto styling tools, for example:įirmware repositories tend to be a little different: My patches clean and tidy! Why this applies to firmware code It took about 10 minutes to add pre-commit to our repo, and it helped me keep can be installed in a Python virtual environment, which our team was already.pre-commit really stands out in these areas: When my coworker (thanks Patrick!) pointed me to pre-commit: I was in the process of adding Arcanist to a repo at one of my previous jobs Reduce friction, after all!
