exportPipeline: Export a pipeline and its components to disk
In anhinton/conduit: A prototype glue system for OpenAPI

Description Usage Arguments Details Value See Also Examples

Exports a pipeline and its referenced components to disk as OpenAPI XML files.

1	exportPipeline(pipeline, targetDirectory)

`pipeline`	A `pipeline` list
`targetDirectory`	Output directory path

Creates a directory named for the pipeline in targetDirectory, then saves pipeline and component XML files in this directory.

The pipeline is exported as ‘pipeline.xml’, and the components are exported as ‘COMPONENT_NAME.xml’.

This functions aims to produce self-contained pipelines with all components available alongside the pipeline XML file.

A list of the XML file paths written

pipeline, savePipeline
