@ -28,17 +28,15 @@ type Lookup func(path string) (io.ReadCloser, error)
// (if the package API depends on cgo-defined entities, the type
// checker won't have access to those).
//
// If lookup is nil, the default package lookup mechanism for the
// given compiler is used, and the resulting importer attempts
// to resolve relative and absolute import paths to canonical
// import path IDs before finding the imported file.
// The lookup function is called each time the resulting importer needs
// to resolve an import path. In this mode the importer can only be
// invoked with canonical import paths (not relative or absolute ones);
// it is assumed that the translation to canonical import paths is being
// done by the client of the importer.
//
// If lookup is non-nil, then the returned importer calls lookup
// each time it needs to resolve an import path. In this mode
// the importer can only be invoked with canonical import paths
// (not relative or absolute ones); it is assumed that the translation
// to canonical import paths is being done by the client of the
// importer.
// A lookup function must be provided for correct module-aware operation.
// Deprecated: If lookup is nil, for backwards-compatibility, the importer
// will attempt to resolve imports in the $GOPATH workspace.
