* Add a button to quote text selected in a message Selecting text in a post in the center channel, RHS or Threads view shows a floating "Quote selection" button at the end of the selection. Clicking it appends the selection as a Markdown blockquote to the message box of the same channel or thread and leaves the caret on an empty line below it, in both the plain text and the WYSIWYG editors. Fixes https://github.com/mattermost/mattermost/issues/39236 * Address review feedback on quoting selected text - Determine the selection direction from its boundary points so a left to right selection that ends on an element containing its start isn't treated as right to left. - Keep a quote queued while the message box is busy rewriting the draft and add it once it's done, but still drop it when the message box can't be used. * Add E2E tests for quoting selected text Cover quoting a selection into the channel message box and posting it with a reply, a right to left selection added after an existing draft, quoting from the RHS into the thread reply box, and typing the reply below the quote in the WYSIWYG editor. Text is selected by dragging the mouse like a user does. * Address UX review feedback on quoting selected text - Keep the Markdown formatting of the quoted text (headings, lists, emphasis, code blocks, links, mentions, hashtags) by converting the selected HTML back to Markdown, in both the plain text and WYSIWYG editors. - Place the quote button next to the first selected character instead of the caret, which browsers report at the end of the previous line when a selection starts at the beginning of a wrapped line. - Don't offer to quote when the target message box can't be used: archived channels, DMs with deactivated users, threads whose root was deleted, or without permission to post. - Make the button reachable with Tab and dismissable with Escape, returning the focus where it was, and show it for selections made without the mouse. - Mix the hover color with the background instead of using transparency. * Update the button visibility ref in a layout effect Writing a ref during render isn't allowed, since React can discard a render without rolling the write back. * Use the shared Turndown converter for quotes Convert quoted selections with utils/turndown.ts, which already handles the markup of rendered messages for pasting, instead of a separate converter, so quoting and copy-pasting a message produce the same Markdown. - Add a rule for user mentions to the shared converter so that they keep the username rather than the display name, for pasting too. - Drop the data-language attribute on code blocks. When only part of a code block is selected, its language label is copied along with the selection instead. * Address dev review feedback on quoting selected text - Don't offer to quote burn-on-read posts, which can't be copied either, so that they aren't kept around after they're deleted. - Leave the user's selection as is instead of narrowing it to the message text, so a selection running into the author name, attachments or reactions can still be copied as a whole. Only the message text is quoted. - Support quoting in channel and thread pop-out windows. --------- Co-authored-by: Mattermost Build <build@mattermost.com>
