Typst is “A new markup-based typesetting system that is powerful and easy to learn”. It’s written in Rust, and particularly attractive because, while providing a CLI interface, it is a proper library that you can easily incorporate into your progress to produce documents. Protip: If you do so, have a look at sys.inputs, it’s awesome!
We live in a capitalist society. Most of Typst is open source including the CLI, library, and IDE support; and the source is Rust so why not share in a Rust community?
