This repository contains all of the recipes used to build the packages at http://anaconda.org/pydy.

PyDy Build Example

For each release of PyDy we upload binaries for the conda package manager to anaconda.org for easy installation using conda. For every conda package there should be a directory containing at least three files: meta.yaml, bld.bat, and build.sh. The directory should be named as such pydy-X.X.X where X.X.X is the PEP 440 compliant version number. For instructions on building a conda package see the conda documentation: http://conda.pydata.org.

The basic process for creating and uploading a new package is as follows:

Install the needed packages:

$ conda update conda
$ conda install conda-build anaconda-client

Create a new directory for the PyDy version and copy the files from the previous version (or use conda skeleton pypi pydy):

$ cp -r pydy-Y.Y.Y/ pydy-X.X.X/

Edit the files to reflect any new changes in to the package (especially dependency changes) and run conda build for each version of Python to build against:

$ conda build --python 2.7 pydy-X.X.X
$ conda build --python 3.5 pydy-X.X.X
$ conda build --python 3.6 pydy-X.X.X

This will build the default package for your computer architecture. Since PyDy is a pure Python package we can generate the packages for other architectures with a single command:

$ conda convert --platform all /tmp/conda-builds/linux-64/pydy-X.X.X-py27_0.tar.bz -o build/pydy-X.X.X/

The converted Windows binaries will be incorrect because the # [win] selector is not honored by the convert command. This means that the PyWin32 dependency must be manually added to each Windows binary before uploading.

Finally, each of these packages can be uploaded to anaconda with:

$ find build/pydy-X.X.X -name *_0.tar.bz -exec anaconda upload --user pydy {} \;

Metapackages

PyDy has a number of optional dependencies so we can create a metapackage that allows all of the optional dependencies to be easily installed. For example, this will create a PyDy 0.3.0 metapackage with all of the dependencies for Linux that will run the examples:

$ conda metapackage pydy-examples 0.3.0 \
  --summary "A metapackage with the full dependencies required to run all of the PyDy examples." \
  --dependencies "pydy ==0.3.0" "ipython-notebook 3.*" "cython >=0.20.1" "theano >=0.7.0" matplotlib

After this is created, conda convert can be used to create a clone for each OS:

$ conda convert --platform all /tmp/conda-builds/linux-64/pydy-examples-X.X.X.tar.bz -o build/pydy-examples-X.X.X/

Now a fully working PyDy environment with all the optional dependencies can be created with:

$ conda create -c pydy -n pydy pydy-examples
