State of Sway - December 2015

Published 2015-12-20 on Drew DeVault's blog

I wrote sway’s initial commit 4 months ago, on August 4th. At the time of writing, there are now 1,070 commits from 29 different authors, totalling 10,682 lines of C (and 1,176 lines of header files). This has been done over the course of 256 pull requests and 118 issues. Of the 73 i3 features we’re tracking, 51 are now supported, and I’ve been using sway as my daily driver for a while now. Today, sway looks like this:

For those who are new to the project, sway is an i3-compatible Wayland compositor. That is, your existing i3 configuration file will work as-is on sway, and your keybindings will be the same and the colors and font configuration will be the same, and so on. It’s i3, but on Wayland.

Sway initially made the rounds on /r/linux and /r/i3wm and Phoronix on August 17th, 13 days after the initial commit. I was already dogfooding it by then, but now I’m actually using it 100% of the time, and I hear others have started to as well. What’s happened since then? Well:

  • Floating windows
  • Multihead support
  • XDG compliant config
  • Fullscreen windows
  • gaps
  • IPC
  • Window criteria
  • 58 i3 commands and 1 command unique to sway
  • Wallpaper support
  • Resizing/moving tiled windows with the mouse
  • swaymsg, swaylock, swaybar as in i3-msg, i3lock, i3bar
  • Hundreds of bug fixes and small improvements

Work on sway has also driven improvements in our dependencies, such as wlc, which now has improved xwayland support, support for Wayland protocol extensions (which makes swaybg and swaylock and swaybar possible), and various bugfixes and small features added at the bequest of sway. Special thanks to Cloudef for helping us out with so many things!

All of this is only possible thanks to the hard work of dozens of contributors. Here’s the breakdown of lines of code per author for the top ten authors:

And here’s the total number of commits per author for each of the top 10 committers:

As the maintainer of sway, a lot of what I do is reviewing and merging contributions from others. So these statistics change a bit if we use number of commits per author, excluding merge commits:

279 Drew DeVault
175 taiyu
102 S. Christoffer Eliesen
96 Luminarys
56 Mikkel Oscar Lyderik
46 Christoph Gysin

5 Yacine Hmito

These stats only cover the top ten in each, but there are more - check out the full list.

So, what does this all mean for sway? Well, it’s going very well. If you’d like to live on the edge, you can use sway right now and have a productive workflow. The important features that are missing include stacking and tabbed layouts, window borders, and some features on the bar. I’m looking at starting up a beta when these features are finished. Come try out sway! Test it with us, open GitHub issues with your gripes and desires, and chat with us on IRC.
