Broken but a working ish editor!!!

you can WRITE in it now. like actually type words into a note and have them save. it’s janky but it works and I’m hyped.

How

the editor is block-based, which was the whole gamble. instead of one big textarea, a note is parsed into blocks (paragraphs, headings, code fences, etc) and you edit one block at a time. the active block shows its raw markdown so you can mess with the syntax, everything else renders. new session.rs in penumbra-editor holds all of it: EditorSession owns the list of BlockEdits, tracks which one’s active, and each block has a mode, Prose (renders as markdown, Enter splits into a new block), Heading (single line, Enter drops the tail into a paragraph below), and Raw (code, Enter is a literal newline). splitting a block at the cursor, merging, undo/redo with a 64-deep snapshot history. it’s a real little document editor.

uhhh

is it good? no! the commit message says “broken” and I mean it. the split logic has edge cases, the cursor does weird things, switching blocks is finicky. but you can open a note, type, and it round-trips to the markdown file on disk, which is the bar I set and it clears it. barely. hehe.

yeah state is hard

to make the editor and the layout worker both able to touch the graph, Universe’s graph is now an Arc<Mutex>. graph() hands back a guard, graph_handle() hands back the Arc for things that want to hold their own lock. had to sprinkle lock_graph() everywhere but it’s the honest cost of sharing state between the UI thread and the physics thread.

oop forgot about this

also implicit links persist now! the auto-associated links used to evaporate on restart because only explicit wikilinks got rebuilt from the files. now they save to their own file and get restored on open (skipping any whose notes are gone). so the constellations you didn’t draw by hand survive a relaunch too.

eeh

and the TODO… got GUTTED. so much got checked off I almost don’t believe it. Slint UI: done. map canvas v1 with pan/zoom/grid/edges/culling: done. spring animation so cards drift to their spots instead of teleporting: done. local neighborhood layout: done. pinned notes as fixed stars (pin via right-drag, right-tap to unpin, and left-dragging one nudges it back toward its pin): done. positions cached with throttled save + save-on-exit: done. physics running off the UI thread on the tokio runtime so the map doesn’t stutter while it’s solving: done. that whole “Slint” section of the roadmap is basically green now.

new-note-pill.slint got added too, a little floating “new note” thing that’s partially broken.

broken editor, but a broken editor that WORKS, which three months ago I could not have said about any part of the UI.

we’re so back :3
