Clone the repository:

If you've already cloned the repository but forgot about the --recursive flag, you can run this:

$ git submodule update --init --recursive

We use Nix for CI and deployment. Make sure you can run nix develop. This also ensures that the pre-commit hooks are installed.

We use stack for development. Make sure you can run stack test smos after following the steps in the stack installation guide.

Checkout the development branch:

$ git checkout development

Enter the nix shell

$ nix develop

Set up your feedback loop. When developing in a single smos package, you can use

nix $ stack test <thepackage> --pedantic --file-watch

When developing accross multiple smos packages, you can use

nix $ stack test --pedantic --file-watch --no-rerun-tests

Some feedback loops are provided, as you should have seen when you ran nix develop. You may want to check if those fit your needs first.

Optionally: Set up a local hoogle server to look up code documentation for smos or its dependencies:

nix $ hoogle serve --local

Make your changes.

Make sure the following commands succeeds locally:

nix $ stack clean
nix $ stack build --test --bench --no-run-benchmarks --pedantic`

Make sure nix flake check succeeds locally.
