Installation

snippy is available on PyPI and can be installed using pip (without external dependencies):

pip install snippy-nextgen

The complete snippy-ng environment (including all dependencies) can be installed using the snippy-ng installer script. This script will install the latest version of snippy-ng and all its dependencies.

curl -sSL https://cpg.org.au/snippy-ng/install.sh | bash -s -- --force

Development

To set up a development environment, clone the repository and install pixi and hatch. Pixi is used to manage external dependencies, and Hatch is used to manage the Python package development.

git clone [e-mail]:centre-pathogen-genomics/snippy-ng.git && cd snippy-ng
# install pixi if not already installed
curl -fsSL https://pixi.sh/install.sh | bash
# install hatch if not already installed
pixi global install hatch

Activate the pixi environment and launch a hatch shell. This will install all dependencies and set up the development environment.

pixi shell
hatch shell
