I see this question got not answers 😞 Is it now possible after 1.5 year?

There are nice extensions on

File

and

Path

now which may help with that

Yeees, but it's about recursive glob, and for that I have not found anything

Then I think you might need to use

FileTreeWalk

I'd like to just write

glob("a/*/b/*.c")

though 😞

You can write an extension using the snippet mentioned in the question you linked if you want to use it this way. I don't think there is more in the stdlib right now, but I don't have extensive knowledge of this area tbh

I can, except as mentioned in OP it is very inefficient for big file trees. I'm fine it to be outside of stdlib, but I can't find any library either.

If you believe it's faster, you could also call a separate process to do an actual glob, but then you're platform dependent

The point is this snippet walks through every file under the given root and then compares the whole path, while the proper glob implementation would skip irrelevant subpaths based on the given pattern.

I think it's a bit beyond the scope of a kotlin-stdlib that doesn't even have cross-platform IO to begin with, unfortunately
