Editing, navigation, and clipboard ​

CodeEditor routes terminal keys through dismissal, assistance, snippet, editor-command, and text layers in a deterministic order. The document remains the authority for edits and selections, while the host owns the clipboard boundary.

Focused usage ​

ts
import { CodeEditor } from '@jsvision/code-editor';

const editor = new CodeEditor({ controller, lineNumbers: true });
editor.focus();
editor.execute('cursor.documentEnd');

Editing and navigation ​

Keyboard commands and mouse gestures update the same selection model. Keep line numbers optional: they consume viewport width but do not change document positions. Selection-aware indentation, history, comment toggling, and caret-follow scrolling all remain transactions over the controller.

Edit, select, move, and inspect revision/caret feedback through the real terminal event path.

Read-only clipboard ​

Read-only means mutations are rejected; focus, navigation, selection, search, and copy can remain available. Route copied text through the application clipboard seam and present only content-free confirmation in logs or status surfaces.

Select source in a locked document, copy it safely, and verify that the document revision never changes.

Limits and practices ​

  • Register custom bindings through the public key-binding API and resolve collisions explicitly.
  • Do not turn read-only into disabled; users still need focus, selection, navigation, and copy.
  • Keep source-bearing clipboard data out of observability messages.
  • Test keys through the real application loop so menu and shell accelerators cannot mask conflicts.
