Comments

This guide is based on the Basic guide. It is recommended to review it for a comprehensive understanding of this guide.

Install dependencies

bash

npm i rete-comment-plugin

Prepare nodes

class Node extends ClassicPreset.Node {
  width = 180;
  height = 140;
}
class Connection<N extends Node> extends ClassicPreset.Connection<N, N> {}

type Schemes = GetSchemes<Node, Connection<Node>>;

Plugin connection

import { CommentPlugin } from "rete-comment-plugin";

const comment = new CommentPlugin<Schemes, AreaExtra>();

area.use(comment);

Add comments programmatically

Adding an inline comment

comment.addInline("Inline comment text", [360, -20], node.dd);

where [360, -20] is the position of the comment, which can be placed freely in relation to the node it is attached to.

Adding a frame comment

comment.addFrame("Frame comment text", [node.id]);

where [node.id] refers to the nodes that are covered by this comment

Selectable comments

import { CommentExtensions } from "rete-comment-plugin";

const selector = AreaExtensions.selector();
const accumulating = AreaExtensions.accumulateOnCtrl();

CommentExtensions.selectable(comment, selector, accumulating);

Edit comment text

The comment text can be edited by RMB. By default, a prompt with an input field will be displayed, but you can customize this.

const comment = new CommentPlugin<Schemes, AreaExtra>({
  edit: async (comment) => {
    return prompt('Edit comment', comment.text)
  }
});

where the edit property must accept an asynchronous function that returns the text for the comment.

Check out the complete result on the Comments example page.
