Heya fellows,
The code of this post can be found on Github (see here).
When a setup.py file was already created, it's pretty simple to go a step further and create an Anaconda package. Anaconda packages store the necessary metadata within a meta.yaml file but when a setup.py file was already created its data can be easily imported by jinja2 templating.
{% set data = load_setup_py_data() %}
package:
name: 'tihttp'
version: {{ data['version'] }}
source:
path: ..
build:
number: 0
entry_points:
{% for entry_point in data['entry_points']['console_scripts'] %}
- {{ entry_point }}
{% endfor %}
script: python -m pip install --no-deps --ignore-installed .
requirements:
build:
- python
- pip
- setuptools
run:
- python
{% for dep in data['install_requires'] %}
- {{ dep.lower() }}
{% endfor %}
test:
imports:
- {{ data['name'] }}
source_files:
- tests
requires:
{% for test_dep in data['extras_require']['dev'] %}
- {{ test_dep.lower() }}
{% endfor %}
commands:
- pytest tests
about:
home: {{ data['url'] }}
license: {{ data['license'] }}
summary: {{ data['description'] }}
doc_source_url: {{ data['url'] + '/blob/master/README.md' }}
Now we can build the package.
$ conda build .
The generated file tihttp-0.1.0-py37_0.tar.bz2 can be found within the anaconda3/conda-build/linux-64 directory. To upload the package to the anaconda repository we have to register and then we can use the anaconda upload command. The package was uploaded to your channel and is now ready for distribution! ?
$ anaconda upload home/niklas/anaconda3/conda-build/linux-64/tihttp-0.1.0-py37_0.tar.bz2
$ conda install -c niklastiede tihttp
But building and uploading packages for different Python interpreter versions and different operating systems is tedious. This work can be automated by a bash script:
#!/bin/bash
export PATH=~/anaconda3/bin:$PATH
pkg='tihttp'
array=( 3.6 3.7 3.8 3.9 )
# delete old built packages
if [[ -d $HOME/conda-bld/ ]]; then
rm -r $HOME/conda-bld/
fi
for i in $HOME/anaconda3/conda-bld/linux-64/$pkg*; do
echo $i
rm $i
done
echo "Deleting old conda packages done!"
# building conda packages
for i in "${array[@]}"
do
echo $i
conda build --py $i .
done
echo "Building conda packages done!"
# converting conda packages to other platforms
platforms=( osx-64 linux-32 linux-64 win-32 win-64 )
for file in $HOME/anaconda3/conda-bld/linux-64/$pkg*; do
echo $file
conda convert --platform all $file -o $HOME/conda-bld/
for platform in "${platforms[@]}"
do
conda convert --platform $platform $file -o $HOME/conda-bld/
done
done
echo "converting packages to other platforms done!"
# uploading packages
find $HOME/conda-bld/**/$pkg*.tar.bz2 | while read file
do
anaconda upload $file
done
echo "Uploading conda packages done!"
Instead of automating the build process locally we could instead use this nice github action Publish Conda! Here's the code snippet for the workflow:
name: publish_conda
on:
release:
types: [published]
jobs:
publish:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: publish-to-conda
uses: fcakyon/conda-publish-action@v1.3
with:
subdir: 'conda'
anacondatoken: ${{ secrets.ANACONDA_TOKEN }}
platforms: 'win osx linux'
The world of anaconda does a great service to the data science community and I hope that this post decreases the barrier for publishing things at anaconda. ? I wish you all a great time!
