Code Editor — src/editor.mjs

CodeMirror 6 editor with q syntax highlighting and execution keybindings.

Conventions

• Exports createEditor(container, onExecute) — factory function, not a class.
• onExecute(code) callback is called when the user presses Ctrl+Enter or Shift+Enter.
• Keybindings are defined in executeKeymap array.
• Theme is darkTheme, defined inline.
• Shares qLanguage + qHighlightStyle from lang-q.mjs.
• Exposed as window.editor for remote JS invocation from q server.

When Modifying

Adding new keybindings

1. Add to the executeKeymap array following the existing Ctrl-Enter / Shift-Enter pattern.
2. Each entry is { key, run } where run receives the EditorView.
3. Use Prec.highest() if the binding must override CodeMirror defaults.
