Steps to reproduce

polybar-msg hook demo 11

Minimal config

[bar/bar_test]
enable-ipc = true

modules-center = demo demo1

[module/demo]
type = custom/ipc
hook-0 = echo hook0
hook-1 = echo hook1
hook-2 = echo hook2
hook-3 = echo hook3
hook-4 = echo hook4
hook-5 = echo hook5
hook-6 = echo hook6
hook-7 = echo hook7
hook-8 = echo hook8
hook-9 = echo hook9
hook-10 = echo hook10

[module/demo1]
type = custom/ipc
hook-0 = echo hook0
hook-1 = echo hook1
hook-2 = echo hook2

Polybar log

No response

Expected behavior

Only the hook of the demo module is triggered

Actual behavior

Given the way the hook message is serialized before being send to polybar : hook:module/<module_name><hook_index>, polybar receives hook:module/demo11 that will match:

• module/demo hook 11
• module/demo1 hook 1

This means both hooks are triggered and the 2 modules are updated.
