= loadwrap

* http://github.com/larsch/loadwrap

== DESCRIPTION:

Wraps loading of Ruby code (Through Kernel#require and Kernel#load)
with your own methods that can change the code before it is parsed and
run by the Ruby interpreter.

== FEATURES/PROBLEMS:

* $LOADED_FEATURES and $" are updated prior to evaluating the
  contents of a script. The MRI behaviour is to update it after the
  script is evaluated.

== SYNOPSIS:

Intercepting loading of scripts from the file system using LoadWrap.loadwrap:

  require 'loadwrap'
  LoadWrap.loadwrap do |filename|
    File.read(filename)
  end

Intercepting parsing of scripts using LoadWrap.filter_code:
  
  require 'loadwrap'
  LoadWrap.filter_code do |code|
    code_munging_method(code)
  end

Intercepting parsetrees using LoadWrap.filter_code (Requires ruby_parser and Ruby2Ruby gems):

  require 'sexpwrap'
  LoadWrap.filter_sexp do |code|
    sexp_munging_method(code)
  end

== REQUIREMENTS:

* ruby_parser (optional)
* Ruby2Ruby (optional)
* sexp_processor (optional)

== INSTALL:

* gem install loadwrap
