mattermost Quote Reply

Mattermost plugin that adds targeted quoting for channel posts and thread replies.

What It Does

• Adds a Quote action next to post hover actions.
• Lets you select part of a message and quote only that fragment.
• Keeps quoting scoped correctly:
  • quotes from the center channel go to the center channel composer;
  • quotes from the RHS thread go to the thread composer.
• Appends quotes to the end of the current draft instead of overwriting what you already typed.
• Turns the quoted text itself into a permalink after the message is sent.

Current UX

• Click Quote on a post to quote the whole message.
• Select text inside a post body to get a small Quote popup.
• Multiple quotes can be added one after another before sending.
• The plugin avoids showing the popup on author names and other non-message UI text.

Install

Download the latest release artifact:

• com.zilosoft.quote-reply-<version>.tar.gz

Then upload it in Mattermost:

1. System Console -> Plugin Management
2. Upload Plugin
3. Activate Zilosoft Quote Reply

If the UI still shows cached assets after upgrade, do a hard refresh in the browser.

Local Development

Requirements:

• Go from go.mod
• Node.js 22
• npm

Install dependencies:

cd webapp
npm ci

Run checks:

cd webapp
npm run lint
npm run check-types
npm test -- --runInBand --watchman=false

Run Go tests:

go test ./...

Build the installable plugin:

make dist

Result:

dist/com.zilosoft.quote-reply-<version>.tar.gz

GitHub Actions

The repository includes two workflows:

• ci.yml: reusable CI on push, PR, and tags
• release.yml: builds the plugin, runs tests, creates checksums, and publishes GitHub Releases for v* tags

To publish a release:

1. Bump plugin.json version
2. Commit the change
3. Push a tag like v0.1.12

The release workflow will attach:

• plugin bundle .tar.gz
• checksums.txt

Notes

• The plugin uses Mattermost webapp extension points and DOM detection, so exact behavior can depend on Mattermost frontend markup.
• Full native inline quote parity would still require a Mattermost core fork.
