Katvan is an editor for Typst files

Katvan is a bare-bones editor for the Typst typesetting system, designed for working with documents whose primary language is written from right to left. Features include live previews, syntax highlighting, spell checking, auto-completion, forward/inverse search and more.

This is free and open source software.

Features include:

• Reasonably good RTL editing:
  • Mostly thanks to Qt’s excellent Rich Text Framework/
  • But also specific additional functionality, for example:
    • Syntax-aware line directionality heuristic.
    • Automatic directionality isolation of inline math and code.
    • Displaying BiDi control characters with a special custom font.
    • Toggling between logical and visual cursor movement.
    • Manually flipping paragraph direction (using both Windows style Ctrl+RShift/LShift, or Firefox style Ctrl+Shift+X).
    • Handy commands to manually insert BiDi control marks and isolates for when the algorithm doesn’t quite lead to the right result (e.g. for some instances of inline raw text).
• Live previews.
• Syntax highlighting.
• Syntax-aware spell checking.
• Autocomplete.
• Typical code editor niceties – auto indentation, bracket insertion, etc.
• Forward and inverse search.
• Modelines.
• Supported on Linux and Windows 10/11.
• Experimental support for macOS 12 (“Monterey”) and above.
