Simple, Convenient, Markdown based task runner.
xc is a task runner similar to Make or npm run, that aims to be more discoverable and approachable.
The problem xc is intended to solve is scripts maintained separately from their documentation. Often a Makefile or a package.json will contain some useful scripts for developing on a project, then the README.md will surface and describe these scripts. In such a case, since the documentation is separate, it may not be updated when scripts are changed or added. xc aims to solve this by defining the scripts inline with the documentation.
For the 6 months or so I’ve been quietly porting tmux from C to Rust. I’ve recently reached a big milestone: the code base is now 100% (unsafe) Rust. I’d like to share the process of porting the original codebase from ~67,000 lines of C code to ~81,000 lines of Rust (excluding comments and empty lines). You might be asking: why did you rewrite tmux in Rust? And yeah, I don’t really have a good reason. It’s a hobby project. Like gardening, but with more segfaults.

Simple way to access various statistics in git repository. Git quick statistics is a simple and efficient way to access various statistics in git repository.
Any git repository may contain tons of information about commits, contributors, and files.
