class CodeRay::Tokens

around to encode it more than once, send it to other algorithms…
You can serialize it to a JSON string and store it in a database, pass it
Tokens gives you the power to handle pre-scanned code very easily:
CodeRay.encoder(:html).encode_tokens(tokens)
tokens.html
tokens.encode(:html)
tokens = CodeRay.scan(‘price = 2.59’, :ruby).tokens
Ruby object that can be send to an Encoder later:
Tokens can be used to save the output of a Scanners in a simple

The Ruby scanner, for example, splits “a string” into:
token actions, for example :begin_group and :end_group.
Some scanners also yield sub-tokens, represented by special

…, ‘# It looks like this’, :comment, …
It looks like this:
* the token kind (a Symbol representing the type of the token)
a token action (begin_group, end_group, begin_line, end_line)
* the token text (the original source of the token in a String) or
A token itself is not a special object, just two elements in an Array:
a Scanner. It’s actually just an Array with a few helper methods.
The Tokens class represents a list of tokens returned from

def begin_group kind; push :begin_group, kind end

def begin_line kind; push :begin_line, kind end 

def begin_line kind; push :begin_line, kind end

def count

Return the actual number of tokens. 
def count
  size / 2
end

def encode encoder, options = {}

options are passed to the encoder.

* a plugin name like :html oder 'statistic'

Encode the tokens using encoder. 
def encode encoder, options = {}
  encoder = Encoders[encoder].new options if encoder.respond_to? :to_sym
  encoder.encode_tokens self, options

def end_group kind; push :end_group, kind end

def end_line kind; push :end_line, kind end 

def end_line kind; push :end_line, kind end

def method_missing meth, options = {}

is used to highlight the tokens.
For example, if you call +tokens.html+, the HTML encoder

Redirects unknown methods to encoder calls.

  encode meth, options
