editor_core library

Stable low-level text editing primitives for terminal editors.

This entrypoint exposes the reusable document, cursor/selection, view, command, history, and decoration layers that power the higher-level editor widgets and TUI text areas.

It is intended for editor implementations, language tooling, and advanced integrations that need lower-level editing surfaces than package:artisanal/editors.dart.
