Types ¶
type Config ¶ added in v0.6.0
type Config struct {
// Dynamic enables evaluting dependencies Vertex Arcs, recursively
Dynamic bool
// Descend enables recursively descending into fields. This option is
// implied by Dynamic.
Descend bool
// Cycles allows a Node to reported more than once. This includes the node
// passed to Visit, which is otherwise never reported. This option can be
// used to disable cycle checking. TODO: this is not yet implemented.
AllowCycles bool
// Rootless enables reporting nodes that do not have a path from the root.
// This includes variables of comprehensions and fields of composite literal
// values that are part of expressions, such as {out: v}.out.
Rootless bool
// pkg indicates the main package for which the analyzer is configured,
// which is used for reporting purposes.
Pkg *adt.ImportReference
}
type Dependency ¶
type Dependency struct {
// Node is the referenced node.
Node *adt.Vertex
// Reference is the expression that referenced the node.
Reference adt.Resolver
// contains filtered or unexported fields
}
A Dependency is a reference and the node that reference resolves to.
func (*Dependency) Import ¶
func (d *Dependency) Import() *adt.ImportReference
Import returns the import reference or nil if the reference was within the same package as the visited Vertex.
func (*Dependency) IsRoot ¶
func (d *Dependency) IsRoot() bool
IsRoot reports whether the dependency is referenced by the root of the original Vertex passed to any of the Visit* functions, and not one of its descendent arcs. This always returns true for Visit().
func (*Dependency) Recurse ¶ added in v0.6.0
func (d *Dependency) Recurse()
Recurse visits the dependencies of d.Node, using the same visit function as the original.
type VisitFunc ¶
type VisitFunc func(Dependency) error
VisitFunc is used for reporting dependencies.
