Overview

Package safetoken provides wrappers around methods in go/token, that return errors rather than panicking.

Index

• func InRange(tf *token.File, pos token.Pos) bool
• func Offset(tf *token.File, pos token.Pos) (int, error)
• func Pos(tf *token.File, offset int) (token.Pos, error)

Functions

func InRange

func InRange(tf *token.File, pos token.Pos) bool

InRange reports whether the given position is in the given token.File.

func Offset

func Offset(tf *token.File, pos token.Pos) (int, error)

Offset returns tok.Offset(pos), but first checks that the pos is in range for the given file.

func Pos

func Pos(tf *token.File, offset int) (token.Pos, error)

Pos returns tok.Pos(offset), but first checks that the offset is valid for the given file.
