@manuscripts/track-changes-plugin v1.8.1

@manuscripts/track-changes-plugin

ProseMirror plugin to track inserts/deletes to nodes and text.

How to use

Requires normal ProseMirror editor dependencies.

1. Install the plugin: npm i @manuscripts/track-changes-plugin
2. Add it to ProseMirror plugins:

import { EditorState } from 'prosemirror-state'
import { EditorView } from 'prosemirror-view'
import { exampleSetup } from 'prosemirror-example-setup'
import { trackChangesPlugin } from '@manuscripts/track-changes-plugin'

import { schema } from './schema'

const plugins = exampleSetup({ schema }).concat(
  trackChangesPlugin({
    debug: true,
  })
)
const state = EditorState.create({
  schema,
  plugins,
})
const view = new EditorView(document.querySelector('#editor') as HTMLElement, {
  state,
})

where schema contains dataTracked attributes for tracked nodes and tracked_insert & tracked_delete marks as shown here: https://github.com/Atypon-OpenSource/manuscripts-quarterback/blob/main/quarterback-packages/track-changes-plugin/test/utils/schema.ts

3. That should start tracking all transactions. You can use the following commands to enable/disable/enter read-only mode:

import { trackCommands, TrackChangesStatus } from '@manuscripts/track-changes-plugin'

// toggle
trackCommands.setTrackingStatus())(view.state, view.dispatch, view)

// enable
trackCommands.setTrackingStatus(TrackChangesStatus.enabled))(view.state, view.dispatch, view)

// disable
trackCommands.setTrackingStatus(TrackChangesStatus.disabled))(view.state, view.dispatch, view)

// sets editor's 'editable' prop to false, making it ready-only
trackCommands.setTrackingStatus(TrackChangesStatus.viewSnapshots))(view.state, view.dispatch, view)

See an example app at https://github.com/Atypon-OpenSource/manuscripts-quarterback/tree/main/examples-packages/client for a more complete boilerplate.

NOTE: If you have multiple versions of prosemirror packages, ensure that track-changes' dependencies prosemirror-model and prosemirror-transform are aliased/deduped to same instance. prosemirror-state and prosemirror-view are only used at type level. Example.

API

As copied from the source.

export const trackChangesPluginKey = new PluginKey<TrackChangesState, any>('track-changes')

/**
 * The ProseMirror plugin needed to enable track-changes.
 *
 * Accepts an empty options object as an argument but note that this uses 'anonymous:Anonymous' as the default userID.
 * @param opts
 */
export const trackChangesPlugin = (opts?: TrackChangesOptions) => Plugin<TrackChangesState, any>

export interface TrackChangesOptions {
  debug?: boolean
  userID: string
  skipTrsWithMetas?: (PluginKey | string)[]
}
export interface TrackChangesState {
  status: TrackChangesStatus
  userID: string
  changeSet: ChangeSet
}
export enum TrackChangesStatus {
  enabled = 'enabled',
  viewSnapshots = 'view-snapshots',
  disabled = 'disabled',
}

export const enableDebug = (enabled: boolean) => void

Commands

/**
 * Sets track-changes plugin's status to any of: 'enabled' 'disabled' 'viewSnapshots'. Passing undefined will
 * set 'enabled' status to 'disabled' and 'disabled' | 'viewSnapshots' status to 'enabled'.
 *
 * In disabled view, the plugin is completely inactive and changes are not updated anymore.
 * In viewSnasphots state, editor is set uneditable by editable prop that allows only selection changes
 * to the document.
 * @param status
 */
export const setTrackingStatus = (status?: TrackChangesStatus) => Command

/**
 * Appends a transaction to set change attributes/marks' statuses to any of: 'pending' 'accepted' 'rejected'.
 * @param status
 * @param ids
 */
export const setChangeStatuses = (status: CHANGE_STATUS, ids: string[]) => Command

/**
 * Sets track-changes plugin's userID.
 * @param userID
 */
export const setUserID = (userID: string) => Command

/**
 * Runs `findChanges` to iterate over the document to collect changes into a new ChangeSet.
 */
export const refreshChanges = () => Command

Actions

Actions are used to access/set transaction meta fields internally. skipTracking is exposed publicly to set track-changes to skip certain transaction.

/**
 * Skip tracking for a transaction, use this with caution to avoid race-conditions or just to otherwise
 * omitting applying of track attributes or marks.
 * @param tr
 * @returns
 */
export const skipTracking = (tr: Transaction) => setAction(tr, TrackChangesAction.skipTrack, true)
