Mattermost for Silver Bullet

This plug provides various integrations with the Mattermost suite of products. Please follow the installation, configuration sections, and have a look at the example.

Features:

• Integration with Silver Bullet Share, allowing you to publish and update a page as a post on Mattermost, as well as load existing posts into SB as a page using the {[Share: Mattermost Post: Publish]} (to publish an existing page as a Mattermost post) and {[Share: Mattermost Post: Load]} (to load an existing post into SB) commands.
• Access your saved posts via the mm-saved query provider
• Unfurl support for posts (after dumping a permalink URL to a post in a page, use the {[Link: Unfurl]} command).
• Boards support is WIP

Installation

Run the {[Plugs: Add]} command and paste in the following URI: github:silverbulletmd/silverbullet-mattermost/mattermost.plug.json

Configuration

In SETTINGS provide the mattermost key with a url and defaultTeam for each server (you can name them arbitrarily):

```yaml
mattermost:
  community:
    url: https://community.mattermost.com
    defaultTeam: core
  silverbullet:
    url: https://silverbullet.cloud.mattermost.com
    defaultTeam: main
```

In SECRETS provide a Mattermost personal access token (or hijack one from your current session) for each server:

```yaml
mattermost:
  community: 1234
  silverbullet: 1234
```

Query sources

• mm-saved fetches (by default 15) saved posts in Mattermost, you need to add a where server = "community" (with server name) clause to your query to select the mattermost server to query.

To make the mm-saved query results look good, it's recommended you render your query results a template. Here is one to start with, you can keep it in e.g. templates/mm-saved:

[{{username}}]({{url}}) in {{#if channelName}}**{{channelName}}**{{else}}a DM{{/if}} at _{{updatedAt}}_ {[Unsave]}:

{{prefixLines (substring message 0 300 " ... (More)") "> "}}

---

Note that the {[Unsave]} button when clicked, will unsave the post automatically 😎

Example use of mm-saved (using the template/mm-saved template above):

<!-- #query mm-saved where server = "community" order by updatedAt desc limit 5 render "template/mm-saved" -->

<!-- /query -->

Posting to a channel

You can use the {[Share: Mattermost Post: Publish]} command to publish the current page to a channel. You will be prompted to select the server and channel to post to. A $share key will be injected into frontmatter after the initial post. Subsequent post edits can be published via the standard {[Share: Publish]} command.

Loading a post into SB

Using the {[Share: Mattermost Post: Load]} command you can load an existing post into your space. All you need for this is to have the Mattermost authentication configured as described above. You will be prompted for a post permalink and a page to save it to. If you are the author of the post, the $share frontmatter will also be set up so you can change the page and push changes back into Mattermost.
