show-utils.sh: fix jq query to get coreutils deps

[lcheylus]

In jq query, the correct regex to select .id is ".*#coreutils[ |@]\d+\.\d+\.\d+"

• with cargo v1.76.0, id = coreutils 0.0.26 (path+file://<coreutils local directory>)
• with cargo v1.77.0, id = path+file://<coreutils local directory>#[email protected]

Fix uutils/coreutils#6242

---

Tests OK on OpenBSD with cargo v1.76 and FreeBSD with cargo v1.77

You say that on cargo 1.76.0, id is something like coreutils 0.0.26 (path+file://<coreutils local directory>), which does not contain a pound/hash/octothorpe/# at all, yet the regex requires it. So I would expect that it doesn't work. Why does it work?

Also, I have a feeling that this regex has been "fixed" more than once in the past, could you add some concrete examples of strings that the regex needs to match, as a comment? This would provide some light assurance that we don't regress when the next "fix" lands.

Sorry I have made an error in my first commit message : the correct regex to select coreutils is is ".*coreutils[ |@]\d+\.\d+\.\d+" (without # hash/pound).

I have pushed a new version of my fix + comments for the different outputs or cargo metadata to find coreutils id with jq / regex.
