o 2.36.1

o is a text editor that is limited to the VT100 standard. It has general syntax highlighting and launches instantly. It might be a good fit for: - Editing git commit messages (using EDITOR=o git commit). - Editing Markdown, and exporting to PDF. - Learning "up and coming" programming languages, like Zig or Rust. - Editing files deep within larger Go or C++ projects. - Solving Advent of Code tasks. - Writing and maintaining to-do lists and project documentation in Markdown.
