Building Python pkg - date2name

Building Python pkg - date2name

[phodina via]

Hi, I'm trying to build a python module date2name. However, I can't use guix import pypi date2name as I get error:

guix import: error: no source release for pypi package date2name 2018.05.09.1

So I just download it from github and attempt the build. But, it does not have a setup.py file and fails in the build phase.
In Guix manual there is option #:use-setuptools? #f  but I also doesn't help.

Could you please provide guidance how to build the package?
(define-module (expanse packages date2name)

#:use-module (guix packages)

#:use-module (guix git-download)

#:use-module (guix build-system python)

#:use-module (guix licenses))

(define-public date2name

(package

(name "date2name")

(version "master")

(source (origin

(method git-fetch)

(uri

(git-reference

(url "https://github.com/novoid/date2name")

(commit version)))

(sha256

(base32

"064kydcry8jswbbvl1g7gg2pqmyz2fqk4j7k81pzlvb1vjnqjphd"))))

(build-system python-build-system)

(arguments

`(#:use-setuptools? #f))

(synopsis "Handling time-stamps and date-stamps in file names")

(description "Per default, date2name gets the modification time of matching files and directories and adds a datestamp in standard ISO 8601+ format YYYY-MM-DD (http://datestamps.org/index.shtml) at the beginning of the file- or directory name.")

Hi Petr,

I had a look at the date2name repository in Github, and it doesn't 
look like it has any instructions for packaging it at all. I'm not 
sure how they build things to distribute over pypi.

At any rate, it looks like it's mostly a matter of marking 
__init__.py as executable, and renaming it to bin/date2name, so 
I've attached a package definition that does that. I have 
confirmed that I am able to build and run it, but I can't confirm 
its behaviour as I don't use the tool.

I hope that helps!

Carlo
