This action sets up the latch CLI and SDK.

Visit us at Fulcrum Genomics to learn more about how we can power your Bioinformatics with setup-latch and beyond.

By default, this action will setup ssh config in ~/.ssh/config for latch commands that require ssh by disabling strict host key checking (StrictHostKeyChecking No for all hosts in the ~/.ssh/config).

The action will optional add the provided latch workspace identifier and token to ~/.latch/workspace and ~/.latch/token files respectively. This is used when registering your local workflow code to Latch (see the register* inputs). See https://console.latch.bio/settings/developer.

Finally, the latch package is installed.

For a full list of available inputs and outputs for this action see action.yaml.

This example shows how to install the latest version of latch and echo the version installed.

This example shows how to register your local workflow code to Latch. The workspace and token are required and accept the workspace identifier and developer token respectively. In this example, they are stored as encrypted secrets.
