Gem (previously called Editor) is a performant and simple plain text editor, created with Prosemirror. The design is very inpsired by Paco Coursey's "Writer".
The goods:
- Fairly lightweight, around 65.5 kB for the whole website.
- Can do a fair bit better here...some of the prosemirror modules can be stripped for this purpose.
- Undo/redo.
- Arrow key movement.
- Basic inline markdown (bold, code, italic), although they can be a little buggy.
- JS source is small and readable.
- CSS source is small and readable. Uses CSS variables for styling.
- Accessible and semantic. Each paragraph becomes a
p
tag, each inline style is appropriately represented. - Playful animated cursor :)
To run: npm run dev
. The build step uses estrella
to bundle/watch and serve
for serving.
Please hit me up on twitter if you like it or have any ideas for features!
To do (in priority):
- Switch to using codemirror so that syntax highlighting becomes easier to dispatch
- Basic markdown syntax highlighting.
- Headings
- Bullet lists
- Numbered lists
- Code block
- Code block syntax highlighting (async loading through prismjs?)
- Cursor shape changes when marks are applied (fatter when bold, slant when italic, rectangle when code)
- Default word-selection (when you start highlighting, it defaults to selecting the whole word your cursor is on).
- Fix sentence-wrapping bug where it overflows sometimes (unreproducible as of yet, unless you paste in a huge text).
- Highlight and animate selection through 3 divs: one on bottom to beginning of line, one sandwiched in b/w, and one from top to end of line
- "Bookmarks" to leave your cursor in a position and travel back to.
Things I'm thinking of adding:
- Table of contents generated from the headings for easy navigation?
- Tree-sitter for incremental markdown parsing? Prosemirror plugin to wrap the wasm bundle?
- Allow theming/setting the color variables in UI?
- Potentially replace prosemirror-view to be more lightweight and integrate cursor and selection "natively"?
- Share urls to save?
