Functions for executing Splitfiles.

execute_commands
(commands: str, params: Optional[Dict[str, str]] = None, output: Optional[splitgraph.core.repository.Repository] = None, output_base: str = '00000000000000000000000000000000') → None¶Executes a series of Splitfile commands.
- Parameters

params – A dictionary of parameters to be applied to the Splitfile (${PARAM} is replaced with the specified parameter value).
output – Output repository to execute the Splitfile against.
output_base – If not None, a revision that gets checked out for all Splitfile actions to be committed on top of it.

rebuild_image
(image: splitgraph.core.image.Image, source_replacement: Dict[splitgraph.core.repository.Repository, str]) → None¶Recreates the Splitfile used to create a given image and reruns it, replacing its dependencies with a different set of versions.
