= RECMA

* http://recma.rubyforge.org/

== DESCRIPTION

The RECMA library will parse JavaScript and return a parse tree.

== Example

  ##

  # Iterate over and modify a JavaScript AST.  Then print the modified

  # AST as JavaScript.

  require 'recma'

  parser = RECMA::Parser.new

  ast    = parser.parse(

    "for(var i = 0; i < 10; i++) { var x = 5 + 5; }"

  )

  ast.each do |node|

    node.value  = 'hello' if node.value == 'i'

    node.name   = 'hello' if node.respond_to?(:name) && node.name == 'i'

  end

  puts ast.to_ecma # => awesome javascript

== Acknowledgments

The original javascript parser was taken from rbnarcissus written by

Paul Sowden.  Thanks Paul!
