# Development
|
|
|
|
Dotbot uses the [Hatch] project manager ([installation instructions][hatch-install]).
|
|
|
|
Hatch automatically manages dependencies and runs testing, type checking, and other operations in isolated [environments][hatch-environments].
|
|
|
|
[Hatch]: https://hatch.pypa.io/
|
|
[hatch-install]: https://hatch.pypa.io/latest/install/
|
|
[hatch-environments]: https://hatch.pypa.io/latest/environment/
|
|
|
|
## Testing
|
|
|
|
You can run the tests on your local machine with:
|
|
|
|
```bash
|
|
hatch test
|
|
```
|
|
|
|
The [`test` command][hatch-test] supports options such as `-c` for measuring test coverage, `-a` for testing with a matrix of Python versions, and appending an argument like `tests/test_shell.py::test_shell_can_override_defaults` for running a single test.

|
### Isolation
|
|
|
|
Dotbot executes shell commands and interacts with the filesystem, and the tests exercise this functionality. The tests try to [insulate][dotbot-conftest] themselves from the machine, but if you prefer to run tests in an isolated container using Docker, you can do so with the following:
|
|
|
|
```bash
|
|
docker run -it --rm -v "${PWD}:/dotbot" -w /dotbot python:3.13-bookworm /bin/bash
|
|
```
|
|
|
|
After spawning the container, install Hatch with `pip install hatch`, and then run the tests as described above.
|
|
|
|
[dotbot-conftest]: tests/conftest.py
|
|
|
|
## Type checking
|
|
|
|
You can run the [mypy static type checker][mypy] with:
|
|
|
|
```bash
|
|
hatch run types:check
|
|
```
|
|
|
|
[mypy]: https://mypy-lang.org/
|
|
|
|
## Formatting and linting
|
|
|
|
You can run the [Ruff][ruff] formatter and linter with:
|
|
|
|
```bash
|
|
hatch fmt
|
|
```
|
|
|
|
This will automatically make [safe fixes][fix-safety] to your code. If you want to only check your files without making modifications, run `hatch fmt --check`.

|
## Packaging
|
|
|
|
You can use [`hatch build`][hatch-build] to create build artifacts, a [source distribution ("sdist")][sdist] and a [built distribution ("wheel")][bdist].
|
|
|
|
You can use [`hatch publish`][hatch-publish] to publish build artifacts to [PyPI][pypi].
|
|
|
|
[hatch-build]: https://hatch.pypa.io/latest/build/
|
|
[sdist]: https://packaging.python.org/en/latest/glossary/#term-Source-Distribution-or-sdist
|
|
[bdist]: https://packaging.python.org/en/latest/glossary/#term-Built-Distribution
|
|
[hatch-publish]: https://hatch.pypa.io/latest/publish/
|
|
[pypi]: https://pypi.org/
|
|
|
|
## Continuous integration
|
|
|
|
Testing, type checking, and formatting/linting is [checked in CI][ci].
|
