Functions

func AssignUnhandledErrors

func AssignUnhandledErrors(packages []*decorator.Package)

AssignUnhandledErrors transforms the program by refactoring calls to functions that return errors to assignments to fresh variables that contain errors

func InsertNilChecks

func InsertNilChecks(packages []*decorator.Package)

InsertNilChecks inserts nil checks in all functions that contains @nonnil as comment for a parameter. If any error is encountered, then the function will be left as is.

func ReturnsError

func ReturnsError(signature types.Object) (*types.Tuple, bool)

ReturnsError returns a pair of a tuple of types and a boolean such that the boolean is true whenever the signature is the signature of a function returning some error.

func WithScope

func WithScope(packages []*decorator.Package, post transform)

WithScope applies the transform post to packages as a post operation in Apply. It first runs the function that builds information necessary to have access to closest scopes within a function. The post transform can use the FuncInfo's various scope operations
