Exalted

An experiment in implementing a code editor using just a 2D graphics library and a font rendering library (tiny-skia and rusttype respectively).

Inspiration

This project is mostly inspired by Emacs and its near-limitless extensibility, however I would be remiss if I didn't also mention Sublime Text and Helix, the former being a blazingly (🚀🚀🚀) fast, user-friendly GUI editor implemented using basically just Skia, and the latter being a batteries included editor with superb defaults.

Planned Features

• The ability to edit text (🤯).
• Syntax highlighting and context-aware editing with Tree-Sitter.
• Support for proportional/variable width fonts and varying font sizes.
• Modal editing, à la Kakoune/Helix (I just love the editing model too much).
• A built-in LSP client, though it (LSP) may not be a great standard, it's a step towards more comprehensive language support without the baggage of IDEs. It may be worth considering providing an interface more general than that which is required by LSP to accommodate any future developments.
• A system akin to major/minor modes in Emacs that allows scoping of particular functionality as well as composition (perhaps inheritance is better for this kind of thing, we shall see).
• A strongly typed configuration language, perhaps some form of Scheme or ML (nothing screams experimental more than an obscure config language 😎). Perhaps Nix can be a good source of inspiration (although the lack of types not so much).
• Other cool stuff (idk it's 3am and I can't think of anything more).

Roadmap

Just making it up as I go along really.

• Create a winit window and render a shape to its surface using tiny-skia, adjusting on resize.
• Incorporate taffy to render some kind of responsize editor layout.
• Shape and render some text using rusttype.
