applying new_icon to one rules changes for all

[rudevdr]

I was looking to disable icon for all application, except one. I was looking to set icon_position via rule but its not available (relevent issue: #638). I tried to get workaround the issue by setting icon_position = left in global and use new_icon in rules. Then I caught this issue.

My dunstrc is something like this.

[global]

icon_position = left

[my-app]
	appname = myapp
	summary = "*"
	timeout = 0

[fix-icon]
	summary = "*"
	new_icon = ""

Expected Behaviour

Only notifications from myapp should display the icon and other icons should not show icon at all.

Actual Behaviour

No icon in all notifications. If new_icon = "" rule is removed, then icon in all notifications is shown.

It looks like setting new_icon = "" in one rule does not respect icon supplied to a notification in all notifications and sets them all to null.

This is working as intended. Rules do not override each other and are checked independently. So in this case what happens is

• All notifications with appname = myapp have their timeout set to 0
• All notifications have their icons disabled

Unfortunately I don't think there are any workarounds to achieve this currently, at least without listing all appnames. For a proper solution subscribe to #645, which should allow more advanced match syntax if it's added.

Ah, I get it now. Thanks for explaining.

As you mentioned in #645, fnmatch would solve this issue. I could change to:

[my-app]
	appname = myapp
	summary = "*"
	timeout = 0

[fix-icon]
	appname = "!myapp"
	summary = "*"
	new_icon = ""

and this will solve this issue.

But still it will be a workaround. Implementing solution mentioned in #638 would be perfect solution for this workaround.

I will close it once fnmatch is supported. But if you think it should be close, please go ahead and close it.

Regex is implemented in #1017. It should be better than fnmatch.
