Getting started

Installation

⚠️ WARNING: The PyPI distribution is outdated. Until it is updated you'll need to install huak from source.

cargo install --git https://github.com/cnpryer/huak.git huak

Then add "$HOME/.huak/bin" to your path.

Create a new project

To create a new project use the new command.

~/github
❯ huak new my-project

Or initialize an existing project

~/github/existing-project 
❯ huak init

huak distinguishes between library and application-like projects. Projects default to the library type if a type isn't specified. Specify the type with either the --lib or --app flag.

Initializing an existing project adds a pyproject.toml to the current directory. Bootstrapping the project with the new command creates a Python project with the following structure:

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ tree .
.
├── pyproject.toml
├── src
│   └── my_project
│       └── __init__.py
└── tests
    └── test_version.py

Note

Without --no-vcs huak generates a git-initialized project.

Manage your dependencies

Add a dependency

Use huak to add dependencies to your Python project.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak add xlcsv

Installer Options

Currently huak uses pip under the hood for package installation. You can pass additional arguments onto pip. Any arguments after -- are handed off to pip install.

Note that huak will use uv instead of pip in the future (see this issue for any updates).

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak add torch torchvision torchaudio -- --extra-index-url https://download.pytorch.org/whl/cu117

huak will add the packages to your pyproject.toml, so passing PEP 508 strings would help persist this behavior for future installs.

Tip

You can also assign dependencies to a group using --group.

Manually trigger dependency installation

Use the init command again to install the project's dependencies.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak init

Use optional dependency groups

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak add --group my-group

Update dependencies

To update a dependency use the update command.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak update xlcsv

Or attempt to update everything.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak update

Remove dependencies

To remove a dependency from the project use the remove command.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak remove xlcsv

Support more of your workflow

Huak ships commands allowing you to format your python code, lint it, and test it.

Format your code

Use the fmt command to format your Python project's code.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak fmt

Using --check

Warning

As of v0.0.20 huak no longer uses black.

Use --check if all you want to do is verify your code is already formatted. Note that huak currently uses ruff to format your code. This means that -- can only pass options to ruff. Use the [tool.ruff] for more configuration.

Warning

huak will exit prior to running with --check if your imports are not sorted. See #510 for the status of this issue.

Lint your code

Use the lint command to lint your Python project's code.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 took 2s 
❯ huak lint

The --fix flag can be used to address any auto-fixable issues.

huak wraps tools like ruff for some of its commands. To configure a wrapped tool such as ruff use the pyproject.toml file:

[tool.ruff]
# ...

huak also uses mypy for type-checking. To disable this behavior use --no-types.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 took 2s 
❯ huak lint --no-types

Note

Currently, since ruff is the default tool used by huak lint, passing additional options with -- is reserved for ruff. To configure mypy use the [tool.mypy] approach. This limitation will be addressed in future versions of huak (see #505).

Test your code

Use the test command to test your project.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0
❯ huak test

Run commands within your project's environment context

You can use huak to run a command within the Python environment your project uses.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak run which python
/Users/chrispryer/github/my-project/.venv/bin/python

Activate the virtual environment

huak also implements an activate command to activate a virtual environment.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak activate

(.venv) bash-3.2$

Note

Currently huak just runs bash --init-file on unix systems and uses powershell on Windows. 

(.venv) PS C:\Users\chris\github\my-project>
See #486 for the status on the activate command.

Manage your Python installations

By default huak will use the first Python interpreter found from your PATH environment variable. You can list these by using the python command.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak python list
1: /Users/chrispryer/.pyenv/shims/python3.11
2: /Users/chrispryer/.pyenv/shims/python3.10
...

So huak would use /Users/chrispryer/.pyenv/shims/python3.11 out of the box. You can use a different installed Python version with use.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak python use 3.10

Distribute your project

Publish to PyPI

If you're building a Python package you'd like to share, use huak build and huak publish to build and publish the project to PyPI.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak build

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak publish

Cleaning up

Use huak clean to clean out the dist/ directory.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 took 26s 
❯ huak clean

Configure Huak

Configure shell completion

With huak completion you can setup shell completion for huak.

my-project on master 📦 v0.0.1 via 🐍 v3.11.0 
❯ huak completion -h
Generates a shell completion script for supported shells. See the help menu for more information on supported shells

Usage: huak completion [OPTIONS]

Options:
  -s, --shell <shell>  [possible values: bash, elvish, fish, powershell, zsh]
  -u, --uninstall      Uninstalls the completion script from your shell init file. If this flag is passed the --shell is required
  -h, --help           Print help

Add huak completion --shell <shell> to your shell's initialization to use this feature.

eval "$(huak completion --shell <shell>)"
