Comments and annotations for Etherpad

Installing this plugin with npm.

pnpm run plugins install ep_comments_page

Comments in the timeslider

Comments are shown read-only in the timeslider and in-place pad history. Each comment lines up with the text it annotates and only appears for the revisions where that text exists, so you can read the discussion as you scrub through history. Suggested changes are shown too, with the original text struck through once the change has been accepted. Toggling Show Comments off hides the comments — both the sidebar and the inline highlight — in history as well.

This works on the latest Etherpad release as well as develop. Older timeslider bundles can't load plugin client hooks, so the read-only viewer is injected as a plain script and reconstructs the comment positions from the server — no core update required. (Reading comments while scrubbing in-place history on the pad URL additionally needs develop's in-place history mode.)

Extra settings

This plugin has some extra features that can be enabled by changing values on settings.json of your Etherpad instance.

Alternative comment display

There is an alternative way to display comments. Instead of having all comments visible on the right of the page, you can have just an icon on the right margin of the page. Comment details are displayed when user clicks on the comment icon:

To use this way of displaying comments, add the following to your settings.json:

// Display comments as icons, not boxes
"ep_comments_page": {
  "displayCommentAsIcon": true
},

Highlight selected text when creating a comment

It is also possible to mark the text originally selected when user adds a comment:

To enable this feature, add the following code to your settings.json:

// Highlight selected text when adding comment
"ep_comments_page": {
  "highlightSelectedText": true
},

Warning: there is a side effect when you enable this feature: a revision is created everytime the text is highlighted, resulting on apparently "empty" changes when you check your pad on the timeslider. If that is an issue for you, we don't recommend you to use this feature.

Who can edit or delete comments

By default a comment can only be edited or deleted by the author who created it (verified server-side from the author's Etherpad session, so it can't be spoofed). To instead let anyone with write access to the pad edit or delete any comment, add the following to your settings.json:

"ep_comments_page": {
  "allowAnyoneToEditComments": true
},

Let read-only viewers comment

By default a read-only viewer cannot add comments (the add-comment button is hidden and the server rejects comment changes from a read-only session). To let read-only viewers annotate a pad without being able to edit its text, enable:

"ep_comments_page": {
  "allowReadonlyComments": true
},

Comments in exported documents

Comments are included when you export a pad. Each commented passage gets a numbered footnote marker ([1], [2], …) and a Comments section is appended listing each comment as [n] author: text (suggested changes are noted too). Because the markers are numbered they stay correlatable in rich formats such as ODT, DOC, DOCX and PDF, where the in-document anchor link is lost — so your comments are not silently dropped when you export. Plain-text (.txt) export omits comments, as the core text exporter has no extension point for them.

Author colour accent

Each comment box shows a left-border accent in its author's colour. This is on by default; disable it with:

"ep_comments_page": {
  "showAuthorColor": false
},

Floating comment button

When text is selected, a small floating button appears next to it for quickly adding a comment. This is on by default; disable it with:

"ep_comments_page": {
  "floatingCommentButton": false
},

All-comments overview

The Settings pane has a "Show all comments" checkbox. Tick it to open a panel listing every comment in the pad; clicking an entry jumps to that comment, and it updates as comments are added or removed. The choice is remembered per pad.

Disable HTML export

By default comments are exported to HTML, but if you don't wish to do that then you can disable it by adding the following to your settings.json:

"ep_comments_page": {
  "exportHtml": false
},

Creating comment via API

If you need to add comments to a pad:

• Call this route to create the comments on Etherpad and get the comment ids:

  curl -X POST http://localhost:9001/p/THE_PAD_ID/comments -d "apikey=YOUR_API_KEY" -d 'data=[{"name":"AUTHOR","text":"COMMENT"}, {"name":"ANOTHER_AUTHOR","text":"ANOTHER_COMMENT"}]'
  

  The response will be:

  {"code":0,"commentIds":["c-VEtzKolgD5krJOVU","c-B8MEmAT0NJ9usUwc"]}
  

• Use the returned comment ids to set the pad HTML via API:

  My comment goes <span class="comment c-VEtzKolgD5krJOVU">here<span>.
  

  Result:

NOTE: Adding a comment to a pad via API will make the other editors with that pad to be alerted, but this feature is only active if your Etherpad is run in loadTest mode. Read the Etherpad Guide for how to enable load testing.
