Installation
============

Before installing this package via pip, please install the necessary
`conda <http://conda.pydata.org/miniconda.html>`_ dependencies:

.. code::

    $ conda create -n smos python=3.12
    $ conda env update -f environment.yml -n smos


Then

.. code::

    $ pip install smos

should work.

Example installation script
---------------------------

The following script will install miniconda and setup the environment on a UNIX
like system. Miniconda will be installed into ``$HOME/miniconda``.

.. code::

   wget https://repo.continuum.io/miniconda/Miniconda-latest-Linux-x86_64.sh -O miniconda.sh
   bash miniconda.sh -b -p $HOME/miniconda
   export PATH="$HOME/miniconda/bin:$PATH"
   git clone git@github.com:TUW-GEO/smos.git smos
   cd smos
   conda env create -f environment.yml
   source activate smos

This script adds ``$HOME/miniconda/bin`` temporarily to the ``PATH`` to do this
permanently add ``export PATH="$HOME/miniconda/bin:$PATH"`` to your ``.bashrc``
or ``.zshrc``

The second to last line in the example activates the ``smos`` environment.

After that you should be able to run:

.. code::

    pytest

to run the test suite.


Supported Products

Currently the following products are supported, additional products can be
added.

Build Docker image
==================
- Check out the repo at the branch/tag/commit you want bake into the image
- Make sure you have docker installed and run the command (replace the tag `latest`
  with something more meaningful, e.g. a version number)

.. code::

    docker build -t smos:latest . 2>&1 | tee docker_build.log

This will execute the commands from the Dockerfile. I.e. install a new environment
from the environment.yml file and install the checked out version of the smos
package.

To build and publish the image online, we have a GitHub Actions workflow in
``.github/workflows/docker.yml``
