Checkout Evaluation Order

spaces has two ways of checking out a workspace:

• Checkout Repo
  : uses git clone to checkout out a repo and evaulates the spaces modules it contains. This is the recommended way for most use cases.
• Specify Workflow Modules
  spaces checkout (workflow): uses workflows scripts as the input files.

Checkout Evaluation Order

During checkout, spaces evaluates all modules in a precise order.

• Checkout-Repo: spaces evaluates the modules in lexicographical order, depth first.
• Checkout (workflow): spaces evaluates the modules in the order they are provided on the command line. Each module is evaluated in depth-first order, meaning that any repos checked out by a module are evaluated before moving on to the next module from the command line.

The load() function always has the //@star/prelude/** files available.

Checkout-Repo Example Evaluation Order

spaces checkout-repo --url=https://github.com/my-org/my-repo ...

And my-repo has:

Checkout (Workflow) Example

spaces checkout --script=workflows/sdk.spaces.star --script=workflows/my-repo.spaces.star ...

The local file located at workflows/sdk.spaces.star is evaluated first. Then any repos checked out by workflows/sdk.spaces.star are evaluated, followed by workflows/my-repo.spaces.star, plus any repos checked out by workflows/my-repo.spaces.star.
