Using mesa_ret

Install mesa. Note that the RET development team are making minor modifications to MESA alongside changes to RET, and these may not be included in the public version of MESA, but may be fundamental for RET functionality. Therefore, as part of the RET install, the local version of MESA should also be installed. This is achieved by running the following command from your local checkout of the ret repository:

pip install ./mesa

Install mesa_ret in editable mode by running the following command from your local checkout of the mesa_ret repository:

pip install -e ./mesa_ret[dev]

Running tests

There are 3 modules to be tested. They each have their own code coverage but (some) shared tests. To run the tests, run the following command from your checkout of the ret repository, assuming an environment that has mesa_ret and all dependencies installed:

./run_tests_with_coverage_report.sh

This will generate coverage reports in the /htmlcov/ directory.

To run the test without coverage reports, simply run:

pytest

Code coverage without the integration tests may be obtained by adding the following flag to any of the above test commands:

--ignore=mesa_ret/testsret/integration_tests/

Generating Documentation

Documentation is automatically produced from Python doc-strings using Sphinx. To create documentation, run the following commands from the mesa_ret folder:

sphinx-apidoc -o sphinx mesa_ret/mesa_ret

This will create .rst files for each module in mesa_ret. If the sphinx folder already contains .rst files for the project and you wish to override them, use the -f flag.

sphinx-build -b html sphinx sphinx-out

This will create an HTML version of the documentation in the sphinx-out folder.

Caveats

This framework is there to make model development easier, as such it is down to the modeller to validate whatever they model.

Operating platform

This framework should be capable of being run on any platform that can support a python environment and has sufficient computing power. The only recommended and/or supported platform is Windows 10 at a level consistent with modern business laptops.
