Output, and label are working for these two configs

type = custom/ipc
label= "%output%"
hook-0 = echo foobar
hook-1 = date +%s
hook-2 = whoami
format= <label>
format-background = #ff2
format-0 = <label>
format-1 = <label>
format-2 = <label>

; Based on colors defined by user
format-0-background= ${color.shade1}
format-2-background= ${color.shade3}
initial = 1
click-left = "#demo.hook.0"
click-right = "#demo.hook.1"
double-click-left = "#demo.hook.2"

[module/demo1]
type = custom/ipc
hook-0 = echo 00
hook-1 = echo 10
format = |<output>|
hook-2 = echo 20

format-0 = |<output>|
format-1 = |<output>|
format-2 = |<output>|
format-0-background= ${color.shade1}
format-1-background= ${color.shade1}
format-2-background= ${color.shade3}
initial = 1
click-left = "#demo1.hook.0"
click-right = "#demo1.hook.1"
double-click-left = "#demo1.hook.2"

```. Format-x seems to work for both. Lemme know if there are any other test cases which I missed before I add details to contributing.md
