Ensure that sway workspaces are always displayed in the same order as
used internally by sway. The previous sorting code always sorted
unnumbered workspaces lexicographically. This isn't the order used by
sway internally. Therefore, commands such as "workspace next" might have
jumped arbitrarily in waybar.
This commit reworks the sorting code such that the internal order is
always obeyed. Additionally, numbered persistent workspaces are inserted
at their natural position at the front of the workspace list while
unnumbered ones are appended. This should match the expectations of
workspace ordering known from sway's behavior.
The changes make the configuration property "numeric-first" unnecessary
as this will always be the case now. There's also no reasonable way
around this behavior now. Otherwise, persistent workspaces would jump
around in the visual representation as soon as they become known to
sway.
Fixes#802
In sway/workspaces, just like disable-scroll turns on/off the ability to
change workspaces by scrolling the mouse add disable-click that turns
on/off the ability to change workspaces by clicking.
Sway provides the workspace "num" property which is an integer number of
the workspace, i.e., workspace "3" -> 3 and also "3dev" -> "3". This
commit 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.
All workspace buttons that are visible on the same output as the current waybar can be styled with the `current_output` css class.
This is really only useful in combination with the `"all-outputs":
true`. Then the workspaces that are on the current output can be styled
differently than the workspace on other outputs, while all are visible
in the waybar.
