The resulting file looks good to me.

[Shawn8901]

i am not having a escpr(1) compatible printer so i can not test, sorry

[Arjun31415]

If review is successful, could this be merged please

[JuliusFreudenberger]

I'm also waiting for this to land, however 2 approvals are needed. That is why this is not merged yet. All we can do afaik is wait patiently.

fyi: a person with commit rights is needed for merging a pr, not actually a specific number of approvals.

[JuliusFreudenberger]

Thanks for the clarification. I was misleaded by the '1 pending reviewer' part.

[Shawn8901]

github visualizes that as there is no approval by a person with commiter rights.

The only issue I can see right now is that in postUnpackPhase the cd command directory is hardcoded.

[SigmaSquadron]

We will need temporary variables.

Try this:

{
  postUnpack = ''
    a=''${src//.tar.gz/} # Trim the file extension.
    b=''${a#-*} # Trim the extra version information
    cd ''${b#*-} # Trim the /nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeee-
  '';
}

[Arjun31415]

yeah, but then i also need to find how to remove the /nix store prefix along with the hash also

[SigmaSquadron]

That's what ${b#*-} does. I've added comments to the lines.

[SigmaSquadron]

Actually, now that I think about it, the first substitution is unnecessary.

[SigmaSquadron]

Try this:

dir=''${src%-*}
cd ''${dir#*-}

Apparently % is for trailing matches????

_{...why? who designed this}

[Arjun31415]

Something else came up, I'll get back to it later today

Cherry-picked over nixos-unstable

[Ekleog]

People reported this working, the diff looks safe to me, and the CI failure seems like a misconfiguration of CI (it looks like CI is trying to automatically request a review from a non-committer?).

@artuuge Considering you didn't answer since the issue was opened I'm landing this to unbreak nixos-unstable; if you don't have commit rights and have a better fix please ping me on any follow-up PR and I'll do my best to review it :)

[Ekleog]

Actually the last-minute check reminded me I still need to wait for ofborg to finish eval before landing, and to run this test too:

@ofborg build epson-escpr

Hopefully this can land soon!

[Ekleog]

Oh weird, apparently ofborg is down? PRs from 14 hours ago don't even have it as pending at all, and this is not the only relatively old-ish PR to not have the eval results back yet.

Welp, guess I'd be very surprised if this broke eval, so I'll just cross my fingers and land as is 🤞

[SigmaSquadron]

the CI failure seems like a misconfiguration of CI

Yes. Infinisil is working on fixing the review requests. #370456 (comment)

Oh weird, apparently ofborg is down?

Not just down, but dead and buried. The Equinix Metal sponsorship that financed OfBorg's build machines ended on 2025-01-01. OfBorg no longer has any builders to run CI on PRs.

[Ekleog]

Thank you for the information ! I completely distanced myself from most of the communication channels, and have been only following from very far away recently, for lack of time

[andrevmatos]

Package is not good: ensure-printers.service errors, cups.service complains that File "/nix/store/sg1cmrdpdj1z3h0s7d076g2jawmxfj2l-cups-progs/lib/cups/filter/epson-escpr-wrapper" not available: No such file or directory, while epson-escpr-wrapper is only found inside a /nix/store/d0rilfvqd699fkzl2r0n8g95c7pzb938-epson-escpr-1.8.6-1/store/26fb46gwc5sbd045nj3dxw4zqpml359i-cups-2.4.11/lib/cups/filter/ folder, so it looks like wrapper is putting a store/ folder in escpr's $out

[jerith666]

I won't have time to open a PR until tomorrow at the earliest, but this fixes the layout problem cited by @andrevmatos:

jerith666@5b07ecc

[andrevmatos]

I can confirm @jerith666 's fix solves the issue and I could print again. Thank you

[Ekleog]

@jerith666 Please ping me on the PR once you make it, I'll try to land it quickly :)
