[Request] Add some kind of heuristic for shortening names displayed on the Winger button

[supersaiyansubtlety]

The Winger button can only actually display the first few characters of a name; I'd love a way to automatically shorten them.

Ideas:

• user-defined regex: if there's a match, display the match; allow group references for output
• predefined heuristic(s); example: if there are capital letters, strip all lowercase letters (leave non-letters)

Since the heuristic has to match the user's naming conventions, I think regex is especially useful for its flexibility.

Since regex is complicated, I think some predefined heuristics could also be useful.

(none of the heuristics would be applied if the whole name fits)

Hi @supersaiyansubtlety, user-defined regex for button badge text is in v2.8.0!

It's just that at the moment, plus sample regex added in the help page. Also an emoji handling setting.

Nothing complicated like heuristics, particularly name-fit checking - that's harder to do than it sounds.

Let me know what you think.

Awesome, thanks!

This pattern is working pretty well for me:
^.{1,3}$|(?<=(?:^| |_))[^\s_](?=.*(?: |_|$))

A couple things though:

1. afaict if there's no match there's no label. There should probably be an option to default to the non-regex truncation behavior in this case
2. it would be more powerful if there was an (optional) substitution field, to use instead of concatenating all the matches

For example my pattern above only gets one character for single-word labels that are longer than 3 characters.

With this (gross hack):
pattern: ^(.{1,3})$|^([^\s_])(?:(?:.*?(?: |_))([^\s_]))(?:(?:.*?(?: |_))([^\s_]))?.*|^(.{1,3}).*
substitution: $1$2$3$4$5

I could make it so that labels with only one word would instead get truncated to their first 3 letters

Wow what does this do? :)

You're right, good catch. But for now wouldn't a conditional |.* at the end do the trick?

substitution

Yeah we probably want that, will look into it.

Sorry if I didn't understand but my first thought here is that truncating anything to the first few letters doesn't seem necessary since the badge by design does that anyway.

The first part makes it so if there are 3 or fewer characters, they're all kept.
The second part matches the first letter of each word (including _ as a separator).

yeah that works

Sorry if I didn't understand but my first thought here is that truncating anything to the first few letters doesn't seem necessary since the badge by design does that anyway.

The point of that regex is to make exceptions for multiple words which is done in the middle part.
The last part could just be replaced with .* though to take advantage of builtin truncation:
^(.{1,3})$|^([^\s_])(?:(?:.*?(?: |_))([^\s_]))(?:(?:.*?(?: |_))([^\s_]))?.*|^.*
actually since the middle part can't match labels with <= 3 characters anyways, the first part isn't needed:
^([^\s_])(?:(?:.*?(?:\s|_))([^\s_]))(?:(?:.*?[\s|_])([^\s_]))?.+|(.+)
