Functions

func Inspect

func Inspect(n ast.Node, f func(n ast.Node) error) (err error)

Inspect is like ast.Inspect but with error handling. Unlike ast.Inspect the function parameter f returns an error and not a bool. The returned error is propagated to the caller, unless it is equal to ErrStop, which in that case indicates the child nodes shouldn't not be inspected (like returning false in the function of ast.Inspect).

func ParseDir

func ParseDir(dir string) (*ast.Package, *token.FileSet, error)

ParseDir invokes ast.ParseDir and returns the first package found that is doesn't has the "_test" suffix.
