Move dag/ to internal/dag/ This is part of a general effort to move all of Terraform's non-library package surface under internal in order to reinforce that these are for internal use within Terraform only. If you were previously importing packages under this prefix into an external codebase, you could pin to an earlier release tag as an interim solution until you've make a plan to achieve the same functionality some other way. 2021-05-17 11:30:37 -05:00			`import "github.com/hashicorp/terraform/internal/dag"`

Provider a marshaler for dag.Graph The dot format generation was done with a mix of code from the terraform package and the dot package. Unify the dot generation code, and it into the dag package. Use an intermediate structure to allow a dag.Graph to marshal itself directly. This structure will be ablt to marshal directly to JSON, or be translated to dot format. This was we can record more information about the graph in the debug logs, and provide a way to translate those logged structures to dot, which is convenient for viewing the graphs. 2016-11-09 08:58:52 -06:00			`func GraphDot(g Graph, opts dag.DotOpts) (string, error) {`
Implement dag.GraphNodeDotter (temporarily) To maintain the same output, the Graph.Dot implementation needs to be aware of GraphNodeDotter. Copy the interface into the dag package, and make the Dot marshaler aware of which nodes implemented the interface. This way we can remove most of the remaining dot code from terraform. 2016-11-09 17:47:46 -06:00			`return string(g.Dot(opts)), nil`
