Lol. This is wild.

Wanted to dip my toes in t.co/ZSDGMufAkd, CC with Opus 4.6 built the editor of my dreams instead: "The beefy love-child of emacs and iA Writer. "

My favorite emacsen bindings + iA Writer's clean typography. I LOVE IT SO MUCH!

Stress-tested with a 100M text file:

  • Opens the file in half a second
  • Scrolling is instant and lag-free
  • Search and scroll-to-first occurrence is instant
  • Select, cut and paste of all text takes ~1s

In short: Bonkers.

Oh, yeah, and of course, it's 100% portable C. Zero Swift: microui, SDL2, OpenGL and stb_truetype.

And finally, for anyone interested, the bindings and chords for writing, in the order of my personal muscle-memory-ness:

  • C-a (beginning of line)
  • C-e (end of line)
  • C-f (forward one character)
  • C-b (backward one character)
  • C-n (next line)
  • C-p (previous line)
  • M-f (forward one word)
  • M-b (backward one word)
  • M-> (end of buffer sets mark)
  • M-< (beginning of buffer sets mark)
  • C-k (kill to end of line, consecutive kills append)
  • C-y (yank, paste from kill buffer)
  • C-/ (undo)
  • C-Space (set mark)
  • C-w (kill region, cut)
  • C-g, ESC (cancel mark)
  • C-s (start/next forward search)
  • C-r (start/next backward search)
  • C-f / C-b (next/prev match while searching)
  • C-g (cancel search)
  • C-x C-s (save file)
  • C-x C-c (quit)
  • Enter/Escape (exit search, keep position)
  • Backspace, Delete, Enter work as expected
