When I started to configure Sway, I found a lot of configurations online, but mostly were exactly the same. I too based my configuration on the given example, but disgressed quite a bit.

In my Sway configuration I have two lines that start an application in a specific way: bindsym Mod4+e exec ~/.config/sway/run-or-raise Emacs emacs bindsym Mod4+w exec ~/.config/sway/run-or-raise Firefox firefox What does this do? First, the “exec” clause calls a python script, run-or-raise. This python scripts wants two arguments. The first one is a container name. It uses swaymsg -t get_tree to get all outputs, work spaces and containers. And then it looks for any container (that is: application, Wayland client) that matches the name.

When I start Sway, I’d like to have Emacs on the left side of workspace 1, and a terminal (here Alacritty) on the right side, Unfortunately, this ~/.config/sway/config except won’t work: exec emacs exac alacritty Because alacritty starts much faster than Emacs. So I’d get the terminal on the right side of the screen. And Emacs on the left. Not good. Instead, I do this: exec emacs for_window [class="^Emacs$"] exec sh -c 'pgrep -x alacritty >/dev/null || alacritty' for_window [app_id="^emacs$"] exec sh -c 'pgrep -x alacritty >/dev/null || alacritty' That is, I start Emacs.

The default rc.lua from Awesome 4.0 turns title bars on. Here I show how you can turn them off, and also how I enable them only for floating clients.

The default rc.lua from the Awesome window manager uses a lot of globalkeys = awful.util.table.join(...) code.

I disliked this because …

• in Lua, the last field of a table cannot have a comma. So often when I moved an entry around, I ended up with a pointless syntax error because of a missing or trailing comma
• adding elements by joining seems somewhat complex
• adding logic, e.g. only adding a keybinding under specific circumstances is suddenly more difficult

So let’s change this …

In this post I show a nice method to define tags and associated layouts, where the tag names change dynamically when the layout changes.

This post shows how you can create a global titlebar. I personally removed the tasklist and replaced this with the titlebar. The tasklist wasn’t good looking anyway and so far I don’t miss the tasklist.

Here are the bash aliases that I like and install almost everywhere.
