Could you use https://pypi.python.org/packages/source/q/qrcode/qrcode-"
instead of the http uri?

Otherwise it looks good to me. I can't run it because I'm running and testing
something myself.

Thanks.

I think it's more welcome if you sent in just one initial patch for a package,
not a patch based on another patch.

should this not be something along the lines of
   (uri (pypi-uri "responses" version))
of which there are lots of examples in python.scm?

Hi Daniel,

Thanks for the patch.

> Subject: [PATCH 3/3] gnu: Add python2-qrcode

nitpicks: A full stop should be added at the end, and the following 
changelog-style line should be added:

* gnu/packages/python.scm (python2-qrcode): New variable.

There was also some trailing whitespace in the patch.

> +

5.3 is the newest version, is there a reason to stick with this older 
version?

I think Andreas' comment still applies here i.e. better to use 'pypi-url'.

Can we make this a native-input ?

> +       ("python2-pillow" ,python2-pillow)

I agree this should be an input, even if it is optional. However, it 
does not get included in the .pth file, does this mean that it is not 
available as usual in an environment. Would you mind please checking this?

How about "qrcode is a library which can be used to generate Quick 
Response (QR) images.  It is recommended that the pillow library be used 
to generate images, though the default Python imaging library can also 
be used.

This should be bsd-3 I think.

Thanks for the updated patch. In future would you mind sending the whole 
patch like as attached? It just makes things easier - thanks.

I noticed that the sha256 did not change, so I changed the source field. 
But perhaps more problematically, I couldn't get the example in the 
README to work. Do you know if this is a problem with the library itself 
or the packing of it?

Ok, thanks

I tried it and I had the same error. I'll try again and I'll fix it.

Thank you for your feedbacks.

[PATCH] gnu: Add python2-qrcode

[Daniel Pimentel]

[-- Attachment #1: Type: text/plain, Size: 357 bytes --]

In attach a full patch. Update URI with Pypi.

I tried:
./pre-inst-env guix environment --pure --ad-hoc python2-qrcode python@2
$ qr "Guix" > guix-qrcode.png

It's work.

But whent import by python shell using:
$ python
> import qrcode
> img = qrcode.make('Some data here')

Not work, probably problem with Pillow (PIL fork).

In cases like this I tend to test outside Guix and see if it works 
there, and if it doesn't work, then report the bug upstream.

OTOH, if it does work, then that points to something amiss with the Guix 
package or its dependencies.

Would you be able to test please? Given that this seems on the face of 
it to be a central part of this package it would be good to know why the 
package isn't working.
Thanks,
