Publish LexImpact-prepare-data to conda

We use two systems to publish to conda:

• A fully automatic in LexImpact-prepare-data CI that publish to an "openfisca" channel. See below for more information.
• A more complex in Conda-Forge CI, that publish to Conda-Forge. See https://www.youtube.com/watch?v=N2XwK9BkJpA for an introduction to Conda-Forge, and https://github.com/openfisca/openfisca-core-feedstock for the project use for Conda-Forge.

We use both as with conda-forge our users get an easiest way to install and use openfisca-core : conda-forge is the default channels in Anaconda and it allow publishing packages that depend on openfisca-core to conda-forge.

Automatic upload

The CI automaticaly upload the PyPi package, see the .github/workflow.yml, step publish-to-conda.

Manual actions made to make it works the first time

• Create an account on https://anaconda.org.
• Create a token on https://anaconda.org/openfisca/settings/access with Allow write access to the API site. Warning, it expire on 2023/01/13.
• Put the token in a CI env variable ANACONDA_TOKEN. The token is set in the global Admin of GitLab, to be available to all project.

Manual actions before CI exist

To create the package you can do the following in the project root folder:

• Edit .conda/meta.yaml and update it if needed:

  • Version number
  • Hash SHA256
  • Package URL on PyPi

• Build & Upload package:

  • If you want to use docker : docker run -ti --rm=true -v $PWD:/data --workdir /data continuumio/anaconda3
  • If you want to use podman : podman run -ti --rm=true -v $PWD:/data --workdir /data docker.io/continuumio/anaconda3
  • conda install -c anaconda conda-build anaconda-client
  • conda build -c conda-forge -c leximpact .conda
  • anaconda login
  • anaconda upload prepare-data-<VERSION>-py_0.tar.bz2
