Allow exceptions to window swallowing

[mrkajetanp]

As far as I can see, under the current implementation window swallowing is pretty much all or nothing - if I add the terminal in the regex, it will swallow any window it spawns. While that's the desired behaviour almost all the time there's occasionally some exceptions (like wev) where you want to keep the default behaviour. Could we add something like swallow_exception_regex for this use case?

how would you even except that to work?? Can't you just make a regex that does not target that one thing that you don't want to swallow?

I think swallow_regex =^(classes)$ but in reverse (not terminals but child windows like wev for example)

Most terminals put the working application on their title, or can be configured to do so, so what about excluding by title?
I'm not particularly good with regex yet, but I think it'd go something like: swallow_regex=class:kitty,title:^(?!wev)$

Yes exactly, other WMs that do swallowing like DWM for instance already have this functionality. Implementation-wise it just boils down to matching against the regex before a window is about to be swallowed to see if it's one of the exceptions or not.

I implemented a PR that does just that, it's the one mentioned right above this comment. I tested it on my machine and now it works as intended.

why this open?

Good question, probably oversight.. I'll close this
