sway/workspaces: sort by the "num" property provided by sway

[f0rki]

Sway provides the workspace "num" property which is an integer number of the workspace, i.e., workspace "3" -> 3 and also "3dev" -> 3. This PR uses this property to sort the workspaces, which makes sense when persistent workspaces or all-output is specified. This commit also adds a new configuration option, whether the numeric workspaces come in front or after workspaces that have non-numeric name.

• I think this should fix issue workspace 10 order is not correct #482.
• Tested only with sway version 1.4
• Always sorts workspaces, regardless of any settings.

Nice thanks!
Should be good for #482
Can you update the wiki?

[f0rki]

@Alexays sure I'll update the wiki

Given that this is fixed, I think I might have misconfigured something on my end?

sway version 1.4-5c32a484 (May 20 2020, branch 'master')
Waybar v0.9.2-140-g759602a (branch 'master')

sway/config

# Workspaces
set $ws1 1:Web
set $ws2 2:Code
set $ws3 3:Other
set $ws4 4:Media
set $ws5 5:Chat

waybar/config

"sway/workspaces": {
    "all-outputs": true,
    "format": " {name} ",
    "persistent_workspaces": {
        "1:Web": [],
        "2:Code": [],
        "3:Other": [],
        "4:Media": [],
        "5:Chat": []
    }
},

This gives me the following workspace order, where Web (1) is placed at the very end:

Thank you for your time.

@imjasonmiller Hmm I think you have stumbled upon a rather strange bug. I tried to reproduce this in addition to my usual numeric workspaces. That did not work, but in a nested sway session I managed to reproduce, but strangely enough it only shows up if the "1:Web" (or "1:X" in my case) workspace is the first workspace that is focused...

When I launch sway and switch to X

However, when I launch sway and switch to C the ordering stays intact.

(the same issue with all other workspaces, such as "Z" or "B")

@imjasonmiller I think this might be the same issue as #777
