pip install dtool-lookup-client-dependency-graph-plugin

This plugin depends on having a dtool-lookup-server with dtool-lookup-server-dependency-graph-plugin installed to talk to.

Looking up dpendency graph of dataset by UUID

To lookup dependency graph starting at dataset UUID:

dtool graph UUID

Specify dependency key to process

To build dependency graph using specific keys for UUIDs:

dtool graph UUID --dependency-keys derived_from

To access specific page of results:

dtool graph UUID --page-number 3 --page-size 40

To show pagination inormation before listing results, use:

dtool --debug graph UUID

You will see info like

INFO - Pagination information: {'total': 1, 'total_pages': 1, 'first_page': 1, 'last_page': 1, 'page': 1}

Generate dot format graph

To generate a dot-format graph instead of JSON list output, use:

dtool graph UUID --dot > graph.dot

or convert to PDF directly with:

dtool graph UUID --dot  | dot -Tpdf > dag.pdf
