MOO editor

A code editor for MOO games in μClient. When the game hands you text to edit (a verb, a description, a note), it opens here with MOO syntax colours, a linter and snippets. You review a diff before anything is sent back.

What it does

• MCP simpleedit (dns-org-mud-moo-simpleedit 1.0). The game's @edit opens the editor. Save to game sends -set with the text, one line per line. A save made on two of your devices reaches the game once.
• LambdaCore local edit (#$# edit name: … upload: …), for MOOs without MCP 2.1. It is off by default. Turn it on per world in Settings → Extensions → MOO editor → Accept LambdaCore local editing. The footer shows the command Save runs ("Saving runs: @program #4:look"). A command that doesn't start with one of the world's upload verbs (Settings → Input; by default @program, @set-note-text, @set-note-value) asks first, once per world. It turns itself off when the game speaks MCP 2.1.
• The editor itself, for any editor μClient opens in MOO code, text or Markdown (IRE.Composer, other extensions):
  • Code mode: line numbers, MOO highlighting, and a linter for unbalanced blocks and undefined variables. Prose mode wraps lines.
  • Snippets: if, for, while, try, tell, fork; in prose, a paragraph break, a rule, quotes and an ellipsis.
  • Preview renders ANSI colour codes in your terminal palette.
  • Diff: Review shows what changed, then Save to game. Ctrl+S does both.
  • Unsaved edits ask before the editor closes. Your draft follows you to your other devices.
  • New text from the game while you are editing shows Take it instead of replacing your work.
  • Colours come from your theme.

Without this extension μClient opens these editors as a plain text box.

How it is built

src/index.ts is the entry (5 KB). It handles the protocols and registers the editor UI with mu.editor.provide. The editor (CodeMirror 6, the MOO language, the theme) is the lazy module dist/editor.js. It is listed in muclient.modules, pinned by sha256, and loaded with mu.modules.load the first time an editor opens (SDK 1.13).

npm install
npm run build      # dist/index.js and dist/editor.js; re-pins the module hash in package.json
npm test           # headless host (@runmu.sh/dev/test)
npm run dev        # dev server; μClient → Extensions → Developer
