Mattermost Markdown

Posted on  by



With file attachments, you can share additional information that will help your team to visually understand your ideas. Sharing videos, voice recordings, screenshots, and photos will make your messages more effective and clear.

Attach Files to Messages¶

You can attach files to messages in the following ways:

  • Use the attachment icon - select the paperclip icon inside the message input box

  • Drag and drop

  • Paste from the clipboard

  • I don't think this is a good candidate for an APR. It may require modifying the marked library itself and there's also a lot of things we'd need to think about such as this requiring that users can edit each other's posts to actually click the checkbox.
  • Summary Image/link preview works with an external image proxy (atmos/camo) only when inline markdown is used. Steps to reproduce Setup and enable an external image proxy: atmos/camo with Mattermost 5.13 Paste a image link as inline markd.

Preview File Attachments¶

Sep 24, 2015 The Magic of Mattermost Markdown We’re happy to announce that Mattermost is adopting Markdown for text rendering. This lets Mattermost users communicate with greater expression and precision through font formatting, emoji, headings, bullet points, tables and many other options.

Mattermost has a built-in file previewer that you can use to:

  • Download files

  • Share public links

  • View media

Select the thumbnail of an attached file to open it in the file previewer.

Downloading Files¶

You can download an attached file by selecting the download icon next to the file thumbnail.

Sharing Public Links¶

Public URLs allow you to share attachments with anyone outside the Mattermost system. To share an attachment, select the thumbnail of an attachment, then select Get Public Link.

Tip

If Get Public Link is not visible in the file previewer, and you prefer that the feature is enabled, you can request your System Admin to enable the feature from the System Console under Site Configuration > Public Links.

Viewing Media¶

The following media formats are supported on most browsers:

  • Images: BMP, GIF, JPG, JPEG, PNG, SVG

  • Video: MP4

  • Audio: MP3, M4A

  • Files: PDF, TXT

Other document previews (such as Word, Excel, or PPT) are not yet supported.

Attachment Limits and Sizes¶

Up to five files can be attached per post.

The default maximum file size is 100 MB, but this can be changed by the System Admin.

Image files can be a maximum size of 6048 pixels x 4032 pixels, or 24 MP (mega pixels), or a raw image file size of approximately 36 MB.

This is probably a coincidence, but after Mattermost announced markdown support last week, Slack announced the same feature yesterday.

Markdown is an easy-to-read, easy-to-write plain text format that can optionally be converted to HTML, which is commonly used in the open source community for documentation.

Last Thursday, Mattermost wrote a blog post on creating richly formatted posts with headings, lists, code blocks, tables and a board range of font formatting.

Yesterday, Slack announced the same thing.

Again, it’s almost certainly coincidence. Also, it’s likely Slack had the idea long before Mattermost–because it wasn’t our idea.

Formatting Text — Mattermost 5.31 documentation

Two months ago, markdown support in Mattermost started as a community feature idea that amassed dozens of votes (though given their size, Slack probably heard the same idea hundreds of times by now…).

What’s striking here is the power of open source software to respond to community feedback.

A small group of people openly contributing ideas and energy can build faster than a company with hundreds of millions of dollars of funding.

It’s an amazing feeling to work with smart, like-minded individuals from around the world to improve a product that we use every day.
