How to Use

Generator

go-dependency-graph --project=<path to project> --result=<result file> --generator=<generator>

Available generator are as follows

• c4_plantuml_component, the default value, more information about that format here : https://github.com/plantuml-stdlib/C4-PlantUML
• json, the struct parse.AstSchema encoded in JSON

With the result written to a file

go-dependency-graph --project=<path to project> --result=<result file>

With the result piped

go-dependency-graph --project=<path to project> > <piped>
