= Looksee

* http://github.com/oggy/looksee

== DESCRIPTION

Looksee lets you examine the method lookup path of objects in ways not
possible in plain ruby.

== SYNOPSIS

Pop this in your .irbrc :

    require 'looksee/shortcuts'

This defines a method +lp+ ("lookup path") which lets you do:

    irb(main):001:0> lp []
    => Array
      &            concat      frozen?      push          taguri
      *            count       hash         rassoc        taguri=
      +            cycle       include?     reject        take
      -            delete      index        reject!       take_while
      <<           delete_at   indexes      replace       to_a
      <=>          delete_if   indices      reverse       to_ary
      ==           drop        insert       reverse!      to_s
      []           drop_while  inspect      reverse_each  to_yaml
      []=          each        join         rindex        transpose
      assoc        each_index  last         select        uniq
      at           empty?      length       shift         uniq!

      collect     entries          group_by  minmax     sort
      count       enum_cons        include?  minmax_by  sort_by
      cycle       enum_slice       inject    none?      take
      detect      enum_with_index  map       one?       take_while
      drop        find             max       partition  to_a
      drop_while  find_all         max_by    reduce     zip

      ===       id                          private_methods
      =~        inspect                     protected_methods
      __id__    instance_eval               public_methods
      __send__  instance_exec               respond_to?
      class     instance_of?                send
      clone     instance_variable_defined?  singleton_methods
      display   instance_variable_get       taint
      dup       instance_variable_set       tainted?
      enum_for  instance_variables          tap
      eql?      is_a?                       to_a
      equal?    kind_of?                    to_enum
      extend    method                      to_s
      freeze    methods                     type
      frozen?   nil?                        untaint

It'll also color the methods according to whether they're public,
protected, private, undefined (using Module#undef_method), or
overridden.  So pretty.  You gotta try it.  The default colors are:

    public:     green
    protected:  yellow
    private:    red
    undefined:  blue
    overridden: black

To remind yourself what each looksee color means in irb:

    lc

By default, it shows public and protected methods.  Add private ones
like so:

    lp [], :private => true
    lp [], :private          # shortcut

Or if you don't want protected:

    lp [], :protected => false

There are variations too.  And you can configure things.  And you can
use it as a library without polluting the built-in classes.  See:

    $ ri Looksee

Enjoy!
