Contributing
Continuous Integration (CI): Each pull request gets automatically tested by gitea. If any errors are detected, it will block pull requests until they're resolved.
Dependency Management: We use the Nix package manager to manage dependencies and ensure reproducibility, making your development process more robust.
Supported Operating Systems
- Linux
- macOS
Getting Started with the Development Environment
Let's get your development environment up and running:
-
Install Nix Package Manager:
- You can install the Nix package manager by either downloading the Nix installer or running this command:
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install
- You can install the Nix package manager by either downloading the Nix installer or running this command:
-
Install direnv:
- To automatically setup a devshell on entering the directory
nix profile install nixpkgs#nix-direnv-flakes
- To automatically setup a devshell on entering the directory
-
Add direnv to your shell:
- Direnv needs to hook into your shell to work.
You can do this by executing following command. The example below will setup direnv for
zsh
andbash
echo 'eval "$(direnv hook zsh)"' >> ~/.zshrc && echo 'eval "$(direnv hook bash)"' >> ~/.bashrc && eval "$SHELL"
- Direnv needs to hook into your shell to work.
You can do this by executing following command. The example below will setup direnv for
-
Create a Gitea Account:
- Register an account on https://git.clan.lol
- Fork the clan-core repository
- Clone the repository and navigate to it
- Add a new remote called upstream:
git remote add upstream gitea@git.clan.lol:clan/clan-core.git
-
Register Your Gitea Account Locally:
- Execute the following command to add your Gitea account locally:
tea login add
- Fill out the prompt as follows:
- URL of Gitea instance:
https://git.clan.lol
- Name of new Login [git.clan.lol]:
- Do you have an access token? No
- Username: YourUsername
- Password: YourPassword
- Set Optional settings: No
- URL of Gitea instance:
- Execute the following command to add your Gitea account locally:
-
Allow .envrc:
- When you enter the directory, you'll receive an error message like this:
direnv: error .envrc is blocked. Run `direnv allow` to approve its content
- Execute
direnv allow
to automatically execute the shell script.envrc
when entering the directory.
- When you enter the directory, you'll receive an error message like this:
-
(Optional) Install Git Hooks:
- To syntax check your code you can run:
nix fmt
- To make this automatic install the git hooks
./scripts/pre-commit
- To syntax check your code you can run:
-
Open a Pull Request:
- To automatically open up a pull request you can use our tool called:
merge-after-ci --reviewers Mic92 Lassulus Qubasa
Debugging
Here are some methods for debugging and testing the clan-cli:
See all possible packages and tests
To quickly show all possible packages and tests execute:
nix flake show --system no-eval
Under checks
you will find all tests that are executed in our CI. Under packages
you find all our projects.

You can execute every test separately by following the tree path nix build .#checks.x86_64-linux.clan-pytest
for example.
Test Locally in Devshell with Breakpoints
To test the cli locally in a development environment and set breakpoints for debugging, follow these steps:
- Run the following command to execute your tests and allow for debugging with breakpoints:
You can placecd ./pkgs/clan-cli pytest -n0 -s --maxfail=1 ./tests/test_nameofthetest.py
breakpoint()
in your Python code where you want to trigger a breakpoint for debugging.
Test Locally in a Nix Sandbox
To run tests in a Nix sandbox, you have two options depending on whether your test functions have been marked as impure or not:
Running Tests Marked as Impure
If your test functions need to execute nix build
and have been marked as impure because you can't execute nix build
inside a Nix sandbox, use the following command:
nix run .#impure-checks
This command will run the impure test functions.
Running Pure Tests
For test functions that have not been marked as impure and don't require executing nix build
, you can use the following command:
nix build .#checks.x86_64-linux.clan-pytest --rebuild
This command will run all pure test functions.
Inspecting the Nix Sandbox
If you need to inspect the Nix sandbox while running tests, follow these steps:
-
Insert an endless sleep into your test code where you want to pause the execution. For example:
import time time.sleep(3600) # Sleep for one hour
-
Use
cntr
andpsgrep
to attach to the Nix sandbox. This allows you to interactively debug your code while it's paused. For example:psgrep -a -x your_python_process_name cntr attach <container id, container name or process id>
Or you can also use the nix breakpoint hook
Standards
- Every new module name should be in kebab-case.
- Every fact definition, where possible should be in kebab-case.
