file
-- import "github.com/robertkrimen/otto/file"
Package file encapsulates the file abstractions used by the ast & parser.
Usage
type File
type File struct {
}
func NewFile
func NewFile(filename, src string, base int) *File
func (*File) Base
func (fl *File) Base() int
func (*File) Name
func (fl *File) Name() string
func (*File) Source
func (fl *File) Source() string
type FileSet
type FileSet struct {
}
A FileSet represents a set of source files.
func (*FileSet) AddFile
func (self *FileSet) AddFile(filename, src string) int
AddFile adds a new file with the given filename and src.
This an internal method, but exported for cross-package use.
func (*FileSet) File
func (self *FileSet) File(idx Idx) *File
func (*FileSet) Position
func (self *FileSet) Position(idx Idx) *Position
Position converts an Idx in the FileSet into a Position.
type Idx
type Idx int
Idx is a compact encoding of a source position within a file set. It can be converted into a Position for a more convenient, but much larger, representation.
type Position
type Position struct {
Filename string // The filename where the error occurred, if any
Offset int // The src offset
Line int // The line number, starting at 1
Column int // The column number, starting at 1 (The character count)
}
Position describes an arbitrary source position including the filename, line, and column location.
func (*Position) String
func (self *Position) String() string
String returns a string in one of several forms:
file:line:column A valid position with filename
line:column A valid position without filename
file An invalid position with filename
- An invalid position without filename
