Conda package

[shangxiao]

Thanks for a much needed way to run black over git diffs ❤️

Would it be possible to please get a conda package setup and uploaded to Anaconda.org?

Here are some instructions for creating a conda package from an existing pypi package: https://conda.io/projects/conda-build/en/latest/user-guide/tutorials/build-pkgs-skeleton.html

Actually it may be preferable to have it contributed to conda forge instead:

• https://conda-forge.org/docs/maintainer/adding_pkgs.html#dev-contribute-pkgs
• Some reasons why: https://conda-forge.org/docs/user/introduction.html#why-conda-forge

I started work on a Conda package, and will resume at some point. It seems that it all happens on the Conda repositories side, with no changes needed in the Darker repo.

My branch is here – I didn't yet create a pull request for it. Could you @shangxiao verify that I'm on the right tracks?

[shangxiao]

I'm not 100% familiar with all the required settings for conda-forge but my cursory look at the recipe shows you're in the right direction 👍 When you submit the pull request to staged-recipes someone from the conda-forge group will give it a proper review and approve it if all's good.

Oh I didn't see you were working on this already, I opened a PR this morning: conda-forge/staged-recipes#14565

It seems that the installation fails on Windows though. Any idea why? Maybe running your CI on windows as well could be a good idea.

[akaihola]

@martinRenou running CI on Windows is a good idea. I don't work with Windows at all though, but I can see there are some examples and instructions in GitHub Actions / Guides / Building and testing Python.

Could you create a Darker issue on GitHub for this?

[akaihola]

For the record, Windows installation issues fixed by #121, and Windows test failures in #124.

Let's make sure the Conda package for 1.2.3 is built and works before closing this issue and the 1.2.3 release milestone. See conda-forge/darker-feedstock#1.

I verified that conda install -c conda-forge darker isort does install Darker 1.2.3. And the installed version does reformat code correctly. Thanks for your contribution @martinRenou!
