Subject: Use get_assigned_output for numbers
X-Git-Tag: 4.16~68^2~1
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=d525eb80aefcd596c5c40750eb9fa3570e5c55ed;p=i3%2Fi3

Use get_assigned_output for numbers

This prohibits the usage of workspaces assigned to other outputs in
create_workspace_on_output.

Eg, with config:
    workspace 1 output fake-0
    workspace 2 output fake-0
and 2 screens workspace 2 would be used for the second screen even
though it is assigned to the first one.

Also introduces a test for workspace assignments that includes the case
described above and some tests that don't fail in the next branch.
