Functions

func Format

func Format(fset *token.FileSet, x ast.Expr) string

Format returns a string representation of the expression.

func HasSideEffects

func HasSideEffects(info *types.Info, e ast.Expr) bool

HasSideEffects reports whether evaluation of e has side effects.

func LineStart

func LineStart(f *token.File, line int) token.Pos

LineStart returns the position of the start of the specified line within file f, or NoPos if there is no line of that number.

func ReadFile

func ReadFile(fset *token.FileSet, filename string) ([]byte, *token.File, error)

ReadFile reads a file and adds it to the FileSet so that we can report errors against it using lineStart.

func Unparen
