Candidate

Canonical upstream: https://github.com/cizra/pycat
Packaging target: current master (no tagged release)
Category: MUD client
Tags: mud-client, terminal, Python, telnet
Primary language/build ecosystem: Python
License: Unlicense / public-domain dedication
License evidence: https://github.com/cizra/pycat/blob/master/LICENSE
Expected Guix packaging difficulty: easy

User-facing deliverable

Small Python MUD client intended for interactive terminal use.

Packaging approach

Package a pinned commit with pyproject or a small custom install phase, install its console entry point, and add a local fake-MUD smoke test.

Known blockers and investigation points

No tagged release; verify current Python compatibility and whether packaging metadata needs patching.

Acceptance checks

Pin an immutable upstream release or commit and record a real Guix source hash.
Build without network access using Guix-provided dependencies; do not download runtimes or plugins during the build.
Preserve all applicable project and bundled-component license notices.
Verify the installed launcher/version output and run an offline protocol smoke test against a local fake MUD endpoint where the platform permits it.
Keep profiles, logs, maps, plugins, and other mutable state outside the store.

Existing-package coverage

Checked on 2026-08-22 against GNU Guix, Nonguix, Guix Science, Guix HPC, Guix Past, Guix R Us, and RDE, plus all states of this repository issue tracker. No same-upstream package or existing ticket was found. GNU Guix already packages TinTin++ and POWWOW; this candidate is distinct.

Implemented and published in signed commit 930326ddab.

Packaged cizra/pycat at immutable commit 55c0389b8be3d5623a707698c00a9baa1f393f4e (Unlicense). The final output is /gnu/store/9v729f594fb6vs94wbf5h9x2hjif52ri-pycat-20240731-1.55c0389.

Verification:

real Guix build and --no-substitutes --check rebuild passed
upstream tests and full Python compileall passed
focused no-network lint passed
loopback proxy smoke verified frontend input, cached server output, and reply delivery
user worlds retain sibling imports and a genuine #reload re-execution (generation 1 to 2)
regression coverage proves a malicious cwd proxy.py cannot hijack pycat core imports
fresh HOME was used and no public MUD server was contacted
