Regex behavior incorrect for 'hints' kitten?

[rexkerr]

Before I submit an issue or try to fix this myself I thought it would be good to get clarification to make sure that I'm not just overlooking or misunderstanding something.

I'm trying to use the hints kitten to map a keystroke to open Jira tasks referenced in git history in the browser. Let's assume that I have two Jira projects, one named PROJ and one named BUGS, and our tickets are in the form of PROJ-#### or BUGS-####. I wrote the following marker, and it works as expected:

I then tried to make a hints mapping that runs an existing script that converts the task ID into the full URL, but it doesn't match the same thing:

As you can see from the bold-face text, it only matches the part in the capture group, not the full regex. I suspect that the hints kitty is using its own mechanism to perform the regex match different than the build-in regex match used by the marker.

I can work around this, and it does what I want it to do, by expanding the regex and duplicating the -[0-9]+ portion over and over, but it makes for an uglier expression.

Shortly after posting I noticed this comment in the documentation for the hints kitten:

If you specify a numbered group in the regular expression only the group will be matched.

So, I suspect this has something to do with my problem, but I don't know how to work around it. I've tried nested groups, but that didn't work either.

...figured it out, reading closer -- it's an implicitly numbered groups. Using a named group works as expected:

"(?P<project>PROJ|BUGS)\-[0-9]+"

I spoke too soon. The documentation also says:

If you specify named groups and a --program then the program will be passed arguments corresponding to each named group of the form key=value.

But that's not what I want. I want the full match to be passed. If I copy to clipboard, it copies the match, as expected, and that's why I thought that things were working, but the behavior is different when calling --program=<script> than when calling --program=-, in which case it sends proj=PROJ rather than the expected match of PROJ-1234.

Awesome, thank you! I didn't think about the non capturing group option, not something that I need very often.
