OCCWL developers and maintainers guide

Installing locally

  • Clone OCCWL into a local directory
  • CD into the cloned repository: cd /path/to/occwl
  • Create an environment
conda env create -f environment.yml
conda activate occwl_dev

Then you can either use setuptools to install occwl locally

pip install .

or you can add the full path to the src/occwl folder to the PYTHONPATH environment variable:

  • Linux:
 export PYTHONPATH=$PYTHONPATH:/path/to/occwl/src/
  • Windows:
set PYTHONPATH=%PYTHONPATH%;path\to\occwl\src

To check everything is working run 

python -m unittest

Running the tests

To run the occwl tests use the following command

python -m unittest tests
