Reliable; tested with Moby Dick.
Easy to understand. 1200 lines of code excluding comments.
Install LÖVE. It's just a 5MB download, open-source and extremely well-behaved.
To run from the terminal, pass this directory to LÖVE, optionally with a file path to edit.
Alternatively, turn it into a .love file you can double-click on:
$ zip -r /tmp/text2.love *.lua
By default, text2.love reads/writes the file lines.txt
in
a directory relative to this app.
To open a different file, drop it on the text2.love window.
While editing text:

No support yet for Unicode graphemes spanning multiple codepoints.
No support yet for right-to-left languages.
If you ever see a crash when clicking on the mouse, it might be because a mouse press and release need to happen in separate frames. Try pressing and releasing more slowly and let me know if that helps or not. This is klunky, sorry.
Can't scroll while selecting text with mouse.
No scrollbars yet. That stuff is hard.
The editor is entirely within edit.lua, which should be easy to include in other LÖVE projects. It depends on one external (but included) library: json.lua.
Initialization and preflight check:
edit.load()
-- one-time initializationedit.is_this_love_version_supported()
edit.preferred_love_version()
Create empty editor within given borders:
editor = edit.new_from_defaults(top, left, right, bottom)
Load and (auto)save files:
edit.load_file(editor, filename)
edit.maybe_autosave(editor, dt)
edit.final_save(editor)
Remember editor settings across restart:
edit.new_from_settings(settings, top, left, right, bottom)
-- caller first loads settings first from some filesettings = edit.settings(editor)
-- caller writes settings to some filePlaces to wire into your LÖVE app:
edit.draw(editor)
edit.key_press(editor, key, scancode, isrepeat)
edit.text_input(editor, t)
edit.key_release(editor, key, scancode)
edit.mouse_press(editor, x,y, mouse_button)
edit.mouse_release(editor, x,y, mouse_button)
edit.mouse_wheel_move(editor, dx,dy)
edit.resize(editor, width, height, right, bottom)
edit.focus(editor, in_focus)
Optional helpers:
edit.update_font_settings(editor, font_height)
-- automatically called by keyboard shortcuts by defaultedit.absolutize(filename)
