Seaglass

Seaglass is a truly native macOS client for Matrix. It is written in Swift and uses the Cocoa user interface framework.

Pre-built binaries

Travis CI is used to build binaries from the GitHub repository. You can find the latest build here.

Building from source

Use Xcode 9.4 on macOS 10.13. Seaglass may require macOS 10.13 as a result of using auto-layout for some table views, which seems to have been introduced with High Sierra. I hope to find an alternate way to relax this requirement.

If you do not already have CocoaPods installed, then install it:

sudo gem install cocoapods

Clone the Seaglass repository and install dependencies:

git clone https://github.com/neilalexander/seaglass
cd seaglass
pod install

Open up Seaglass.xcworkspace in Xcode and build!

Things that work

• Logging in to a homeserver you are already registered with
• Creating and leaving rooms and direct chats
• Seeing rooms that you have already joined
• Message redaction
• Posting text to rooms with Markdown formatting
• Changing some room settings (history visibility, join rules, name, topic, aliases)
• Message coalescing
• End-to-end encryption in rooms you are already joined to

Things that don't work

• Anything else that isn't listed above!

Goals

• Notifications for direct messages, highlights, invites, etc.
• Better user interface for verifying E2E devices/users
• Look and feel like a first-class citizen on macOS

Disclaimer

At this stage it is early in development and stands a good chance of being buggy and unreliable. I'm also not a Swift expert - I only started using Swift three or four days before my initial commit - and this code is probably awful. You've been warned. :-)
