Downloading and Installation
============================

Setting Up the Environment
--------------------------

.. note::
   * STARDIS is only supported on macOS and GNU/Linux. Windows users can run STARDIS on a virtual machine.

   * STARDIS packages and dependencies are distributed only through the `conda <https://docs.conda.io/en/latest/>`__ package management system, therefore installation requires a conda distribution to be installed on your system. STARDIS uses `Miniconda <https://conda.io/projects/conda/en/latest/user-guide/install/index.html>`__ or `Mamba <https://mamba.readthedocs.io/en/latest/installation/mamba-installation.html>`__ by default. Other distributions are untested.

STARDIS uses exclusively the packages in the TARDIS enviroment, as well
as using the TARDIS code itself. We strongly suggest that users create a separate
environment for STARDIS. To do this, run
the following in the terminal (replacing ``{platform}`` with
``linux-64``, ``osx-64``, or ``osx-arm64`` as applicable). Cuda is not currently supported.

.. code-block:: bash

   $ cd <path-to-stardis-directory>
   $ wget -q https://raw.githubusercontent.com/tardis-sn/stardis/main/conda-{platform}.lock
   $ conda create --name stardis --file conda-{platform}.lock
   $ conda activate stardis
   $ pip install git+https://github.com/tardis-sn/tardis.git@release-2024.08.25

The third command (``conda activate stardis``) activates the
environment, which is necessary to correctly install STARDIS using the directions below.

If you are using Mamba, the steps are similar:

.. code-block:: bash

   $ cd <path-to-stardis-directory>
   $ wget -q https://raw.githubusercontent.com/tardis-sn/stardis/main/conda-{platform}.lock
   $ mamba create --name stardis --file conda-{platform}.lock
   $ mamba activate stardis
   $ pip install git+https://github.com/tardis-sn/tardis.git@release-2024.08.25
   
Downloading and Installing STARDIS
----------------------------------

.. note::
   Both of the below instructions should be run with your ``stardis`` virtual environment activated. That is, you should run ``$ conda activate stardis`` or ``$ mamba activate stardis`` if you are using conda or mamba, respectively, in the terminal before you continue with the directions below. 

For Non-Developers
^^^^^^^^^^^^^^^^^^

STARDIS can be downloaded for **non-developers** by running

::
   
   $ pip install git+https://github.com/tardis-sn/stardis.git@main

in the terminal.

For Developers
^^^^^^^^^^^^^^

**Developers** should fork and clone the STARDIS repository.
First, `fork the
repository <contributing/editing_stardis.rst#creating-a-fork>`__ and `configure
GitHub to work with SSH
keys <https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent>`__,
and then run the following in the terminal:

::

   $ git clone git@github.com:<username>/stardis.git
   $ cd stardis
   $ git remote add upstream git@github.com:tardis-sn/stardis.git
   $ git fetch upstream
   $ git checkout upstream/main
   $ pip install -e .[test,docs]
