Editor compatibility

Layer：Shared document capability

Editor	Status	Assembly and boundaries
Classic	Requires integration	ClassicTextDiagram — The shared extension defines content and host ports. Use the Classic adapter below for its workspace and product interaction, without installing both the base extension and its replacement.
Block	Supported	createBlockEditorPreset — The default createBlockEditor preset installs this capability. Configure the corresponding preset child; graphic editing uses the preset's workspace ports, while persistence and assets remain host-owned. Avoid duplicate extensions.

“Supported” means the product assembly above exists; interaction, host services and file formats retain their own conditions. See status and integration rules. Licensing is shown separately.

Installation

pnpm add @quirekit/extension-text-diagram@alpha

Install in Editor extensions. The host supplies a view, container and persistence; see Quick start.

import { TextDiagram } from '@quirekit/extension-text-diagram'

Use compatible versions available from your distribution source. This site uses the Alpha workspace. License labels come from package metadata; see support and licensing.

These snippets use an existing host element named element. The host owns container sizing and persistence; call instance.destroy() on teardown. Avoid duplicating preset capabilities and supply required host ports before installation.

Classic · Requires integration

The shared extension defines content and host ports. Use the Classic adapter below for its workspace and product interaction, without installing both the base extension and its replacement.

ClassicTextDiagram

import { createClassicEditor } from '@quirekit/classic-editor'
import '@quirekit/classic-editor/styles.css'
import { ClassicTextDiagram } from '@quirekit/classic-text-diagram'

const instance = createClassicEditor({
  element,
  extensions: [ClassicTextDiagram],
})

Block · Supported

The default createBlockEditor preset installs this capability. Configure the corresponding preset child; graphic editing uses the preset's workspace ports, while persistence and assets remain host-owned. Avoid duplicate extensions.

createBlockEditorPreset

import { createBlockEditor } from '@quirekit/block-editor'
import '@quirekit/block-editor/styles.css'

const instance = createBlockEditor({
  element,
  content: { type: 'doc', content: [{ type: 'paragraph' }] },
})

Configuration

These are extension-level defaults. Presets can override them; they are distinct from current document attributes. See configuration.

open

Open an authoring workspace for the captured target and return a disposable UI task. Recheck the target before asynchronous submission.

Type：((request: TextDiagramEditRequest, editor: QuireEditor) => { close(): void; }) | null

Default：null

render

Offscreen renderer used by Agent edits; absent hosts cannot render for the Agent.

Type：TextDiagramRenderer | null | undefined

Default：null

Commands and runtime

These commands are supplied directly by this extension. Availability depends on the installed schema, selection and protection policy; query editor.can() first.

Command	Parameter signature
`insertTextDiagram`	`insertTextDiagram(request: TextDiagramInsertion)`
`updateTextDiagram`	`updateTextDiagram(request: TextDiagramUpdate)`

These are parameter signatures. See commands and controls to connect UI while retaining one transaction/history authority.
