By default, dbg uses log (log.Println, log.Printf, log.Panic, etc.) for output.
However, you can also provide your own output destination by invoking dbg.New with
a customization function:
import (
"bytes"
Dbg "github.com/robertkrimen/dbg"
"os"
)
# dbg to os.Stderr
dbg, dbgf := Dbg.New(func(dbgr *Dbgr) {
dbgr.SetOutput(os.Stderr)
})
# A slightly contrived example:
var buffer bytes.Buffer
dbg, dbgf := New(func(dbgr *Dbgr) {
dbgr.SetOutput(&buffer)

# file
--
import "github.com/robertkrimen/otto/file"
Package file encapsulates the file abstractions used by the ast & parser.
## Usage
#### type FileSet
```go
type FileSet struct {
}
```
A FileSet represents a set of source files.
#### func (*FileSet) AddFile
```go
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) Position
```go
func (self *FileSet) Position(idx Idx) *Position
```
Position converts an Idx in the FileSet into a Position.
#### type Idx
```go
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
```go
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
```go
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

### Warning
The parser and AST interfaces are still works-in-progress (particularly where
node types are concerned) and may change in the future.
## Usage
#### func ParseFile
```go
func ParseFile(fileSet *file.FileSet, filename string, src interface{}, mode Mode) (*ast.Program, error)
```
ParseFile parses the source code of a single JavaScript/ECMAScript source file
and returns the corresponding ast.Program node.
If fileSet == nil, ParseFile parses source without a FileSet. If fileSet != nil,
ParseFile first adds filename and src to fileSet.
The filename argument is optional and is used for labelling errors, etc.
src may be a string, a byte slice, a bytes.Buffer, or an io.Reader, but it MUST
always be in UTF-8.
// Parse some JavaScript, yielding a *ast.Program and/or an ErrorList
program, err := parser.ParseFile(nil, "", `if (abc > 1) {}`, 0)
#### func ParseFunction
```go
func ParseFunction(parameterList, body string) (*ast.FunctionLiteral, error)
```
ParseFunction parses a given parameter list and body as a function and returns
the corresponding ast.FunctionLiteral node.
The parameter list, if any, should be a comma-separated list of identifiers.
#### func ReadSource
```go
func ReadSource(filename string, src interface{}) ([]byte, error)
```
#### func TransformRegExp
```go
func TransformRegExp(pattern string) (string, error)
```
TransformRegExp transforms a JavaScript pattern into a Go "regexp" pattern.
re2 (Go) cannot do backtracking, so the presence of a lookahead (?=) (?!) or
backreference (\1, \2, ...) will cause an error.
re2 (Go) has a different definition for \s: [\t\n\f\r ]. The JavaScript
definition, on the other hand, also includes \v, Unicode "Separator, Space",
etc.
If the pattern is invalid (not valid even in JavaScript), then this function
returns the empty string and an error.
If the pattern is valid, but incompatible (contains a lookahead or
backreference), then this function returns the transformation (a non-empty
string) AND an error.
#### type Error
```go
type Error struct {
Position file.Position
Message string
}
```
An Error represents a parsing error. It includes the position where the error
occurred and a message/description.
#### func (Error) Error
```go
func (self Error) Error() string
```
#### type ErrorList
```go
type ErrorList []*Error
```
ErrorList is a list of *Errors.
#### func (*ErrorList) Add
```go
func (self *ErrorList) Add(position file.Position, msg string)
```
Add adds an Error with given position and message to an ErrorList.
#### func (ErrorList) Err
```go
func (self ErrorList) Err() error
```
Err returns an error equivalent to this ErrorList. If the list is empty, Err
returns nil.
#### func (ErrorList) Error
```go
func (self ErrorList) Error() string
```
Error implements the Error interface.
#### func (ErrorList) Len
```go
func (self ErrorList) Len() int
```
#### func (ErrorList) Less
```go
func (self ErrorList) Less(i, j int) bool
```
#### func (*ErrorList) Reset
```go
func (self *ErrorList) Reset()
```
Reset resets an ErrorList to no errors.
#### func (ErrorList) Sort
```go
func (self ErrorList) Sort()
```
#### func (ErrorList) Swap
```go
func (self ErrorList) Swap(i, j int)
```
#### type Mode
```go
type Mode uint
```
A Mode value is a set of flags (or 0). They control optional parser
functionality.
```go
const (
IgnoreRegExpErrors Mode = 1 << iota // Ignore RegExp compatibility errors (allow backtracking)
)
```

#### type Token
```go
type Token int
```
Token is the set of lexical tokens in JavaScript (ECMA5).
#### func IsKeyword
```go
func IsKeyword(literal string) (Token, bool)
```
IsKeyword returns the keyword token if literal is a keyword, a KEYWORD token if
the literal is a future keyword (const, let, class, super, ...), or 0 if the
literal is not a keyword.
If the literal is a keyword, IsKeyword returns a second value indicating if the
literal is considered a future keyword in strict-mode only.

#### func (Token) String
```go
func (tkn Token) String() string
```
String returns the string corresponding to the token. For operators, delimiters,
and keywords the string is the actual token string (e.g., for the token PLUS,
the String() is "+"). For all other tokens the string corresponds to the token
name (e.g. for the token IDENTIFIER, the string is "IDENTIFIER").

Copy is useful for saving some time when creating many similar runtimes.
This implementation is alpha-ish, and works by introspecting every part of the

report if you notice any inadvertent sharing of data between copies.
