Functions

func Calls

func Calls(fset *token.FileSet, f *ast.File, fn string) ([]*ast.CallExpr, error)

Calls returns the calls to a given function or method specified as a qualified name (e.g. gnd.la/i18n.T or gnd.la/app.Context.T).

func Ident

func Ident(node ast.Expr) string

func Importer

func Importer(imports map[string]*ast.Object, path string) (*ast.Object, error)

func Imports

func Imports(f *ast.File, pkg string) (string, bool)

Imports return whetever the given ast.File imports the package named pkg. It also returns its local imported name.

func New

func New(p *build.Package, mode parser.Mode) (*token.FileSet, *ast.Package, error)

func ObjectName

func ObjectName(obj *ast.Object) (pkg string, typ string)

ObjectName returns the object package and type name for the given ast.Object.

func ParseFiles

func Selector

func Selector(expr ast.Expr) (x string, sel string)

func StringLiteral

func StringLiteral(f *token.FileSet, n ast.Expr) (string, *token.Position)
