Types

type Node added in v0.4.0

type Node struct {
	// contains filtered or unexported fields
}

func Graph added in v0.4.0

func Graph(fset *token.FileSet,
	files []*ast.File,
	pkg *types.Package,
	info *types.Info,
	directives []lint.Directive,
	generated map[string]generated.Generator,
	opts Options,
) []Node

type NodeID added in v0.4.0

type NodeID uint64

OPT(dh): 32 bits would be plenty, but the Node struct would end up with padding, anyway.

type Object added in v0.4.0

type Object struct {
	Name      string
	ShortName string
	// OPT(dh): use an enum for the kind
	Kind            string
	Path            ObjectPath
	Position        token.Position
	DisplayPosition token.Position
}

type ObjectPath added in v0.4.0

type ObjectPath struct {
	PkgPath string
	ObjPath objectpath.Path
}

type Options struct {
	FieldWritesAreUses     bool
	PostStatementsAreReads bool
	ExportedIsUsed         bool
	ExportedFieldsAreUsed  bool
	ParametersAreUsed      bool
	LocalVariablesAreUsed  bool
	GeneratedIsUsed        bool
}

type Result

type Result struct {
	Used   []Object
	Unused []Object

	// contains filtered or unexported fields
}

func (*SerializedGraph) Dot added in v0.4.0

func (g *SerializedGraph) Dot() string

Dot formats a graph in Graphviz dot format.
