populate_pipeline

Populate Pipeline

Generates the _pipeline/ directory with pipeline.nix and dag.json. Optionally builds the pipeline with full Nix-native orchestration support. If the pipeline contains unexpanded dynamic branching patterns (map_pattern, cross_pattern), they are automatically expanded before population.

Parameters

• p (Pipeline): The pipeline to populate.

• build (Bool): (Optional) Whether to trigger the Nix build immediately. Defaults to false.

• verbose (Int): (Optional) Nix build verbosity level. 0 keeps build failures quiet; values above 0 print failed node logs.

• dry_run (Bool): (Optional) Perform a dry run via Nix (--dry-run), returning a DataFrame of planned actions without executing.

• nix_options (Dict): (Optional) A dictionary of Nix orchestration options:

Returns

A status message, structured build log, or dry-run plan DataFrame.
