Packaging Python code with conda

Most of the custom conda packages required for MicroDrop are hosted on the wheeler-mirofluidics and sci-bots channels. Starting with MicroDrop 2.8, plugins are also conda packages and they are hosted on their own microdrop-plugins channel.

Below are a few common commands that are useful for developing/building conda packages for MicroDrop.

Add channels

conda config --add channels conda-forge &
conda config --add channels wheeler-microfluidics &
conda config --add channels sci-bots

Show channels

conda config --show-sources

Install a local package in development mode

conda develop PATH_TO_PACKAGE

This works by creating a conda.pth file in site-packages.

Install build dependencies

conda install constructor conda-build git constructor-git nsis=3.0

Build a package

conda clean --source &
conda build .conda-recipe

Note 1: Built packages are cached in the %CONDA_PREFIX%\conda-bld\win-32 directory.
Note 2: Running git clean --source is necessary to delete the git cache and prevent the package from being marked as a dev build (conda checks out a new branch if the cache exists). The cache is located at %CONDA_PREFIX%\conda-bld\git_cache\C_\Users\ryan\Documents\dev\python.

Install package from local cache

You could use this, e.g., when you want to install a package that you have built using conda build .conda recipe.

conda install --use-local PACKAGE_NAME

Upload a package

anaconda upload -u wheeler-microfluidics XXX.tar.bz2

Build the MicroDrop installer (uses miniconda-recipe)
