-
-Package file encapsulates the file abstractions used by the ast & parser.
-
-## Usage
-
-#### type File
-
-```go
-type File struct {
-}
-```
-
-
-#### func  NewFile
-
-```go
-func NewFile(filename, src string, base int) *File
-```
-
-#### func (*File) Base
-
-```go
-func (fl *File) Base() int
-```
-
-#### func (*File) Name
-
-```go
-func (fl *File) Name() string
-```
-
-#### func (*File) Source
-
-```go
-func (fl *File) Source() string
-```
-
-#### 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) File
-
-```go
-func (self *FileSet) File(idx Idx) *File
-```
-
-#### 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

-    import "github.com/robertkrimen/otto/parser"
-
-Package parser implements a parser for JavaScript.
-
-    import (
-        "github.com/robertkrimen/otto/parser"
-    )
-
-Parse and return an AST
-
-    filename := "" // A filename is optional
-    src := `
-        // Sample xyzzy example
-        (function(){
-            if (3.14159 > 0) {
-                console.log("Hello, World.");
-                return;
-            }
-
-            var xyzzy = NaN;
-            console.log("Nothing happens.");
-            return xyzzy;
-        })();
-    `
-
-    // Parse some JavaScript, yielding a *ast.Program and/or an ErrorList
-    program, err := parser.ParseFile(nil, filename, src, 0)
-
-
-### 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.

-    const
-    class
-    enum
-    export
-    extends
-    import

-
-    implements
-    interface
-    let
-    package
-    private
-    protected
-    public
-    static
-
-#### 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").
