I built a Markdown like text format for writing technical reports. I was fed up with Word and I wanted a plain text language that supports tables, footnotes, auto validated references to any part of the document, syntax highlighting of code blocks, comments, math equations, table of contents, etc... Unfortunately, existing solutions are all slow or written with some bizarre toolchains that are a pain to set up.
I wrote it from scratch in Go with very few dependencies, so I can compile it to a single binary that should work on all platforms. It outputs .html or .tex which is then compiled to a PDF via Xelatex. Since Latex is pain to deal with, I wanted to generate pdf directly, but life got in a way so... it's not exactly a finished project, but at least I enjoy using it.
You should take a look at the markdown TUI glow (or some of the other projects on charmbracelet) and see if there's anything you can contribute from your work. It's all in Go as well iirc.
