Usage

Keybinds:

  • Arrow keys/ Ctrl+b/f/n/p for basic cursor navigation
  • Alt + left/right to start or extend selection
    • in selection mode, parenthesis (/) and divide / keys will wrap the selected block in the corresponding command
  • Tab to go out a block
  • Press \ to enter a \command (e.g. \alpha or \frac), when you're done, hit Space. While entering a command, you can hit Tab to see a list of available commands (there's no autocomplete, you still have to type it out yourself)
  • Enter for a new equation in a new line
  • Ctrl+k to go to previous line, Ctrl+j to go to next line

Supported Symbols and Commands

There is no standard support table or even a goal, if I ever feel like turning this into a serious project, I would start from KaTeX, but that probably won't happen :P.

Take a look at command_def.gofor a list of all recognized latex commands.

I started this project when I was learning parsing, and this remains as a toy project in which I add stuff when I feel like doing so. Feature requests and whatnot is welcome, but I probably won't do anything.

Other interesting stuff I might try in the future:

  • reactive-programming styled rendering
  • undo
  • autocomplete
  • using parsing libraries for a declarative approach
  • go-specific memory optimizations
  • rendering on other, non-TUI platforms (WASM!)
