## Installation

To install the CORSIKA 8 Python library, you will need Python >= 3.6. The below
instructions are assuming that `python` refers to Python 3.\*. If `python` still
refers to Python 2.\*, please replace `python` with `python3` and `pip` with
`pip3`.

To install this package, change into the `corsika/Python` directory and run

    pip install --user -e .

You can verify that the installation was successful by trying to import `corsika`

    python -c 'import corsika'

## Running the Tests
    
If you wish to develop new features in `corsika`, you will also need to install
some additional dependencies so you can run our unit tests. These can be
installed with

    pip install --user -e '.[test]'

Once that is completed, you can run the unit tests directory from the `corsika` directory

    python -m pytest tests

## Development Guide

`corsika` is a type Python package with type-checking using
[Mypy](mypy-lang.org) and all code is formatted with the
[Black](https://black.readthedocs.io/en/stable/) formatter.

All code must pass these checks, as well as several others, before it can be
merged into CORSIKA. A `Makefile` is provided to simplify running these in
tasks.

    make mypy   # this will run the mypy type checker
    
    make isort  # this will automatically sort `import` statements
    
    make black  # this will automatically format your code
    
    make flake  # this checks that all code passes our linting rules
    
    make tests  # this runs our test suite
    
Lastly, we provide an `all` target that runs *all* of the above in the sequence shown above:

    make all  # run all of the above tests
