Class: ItsATrap

Inherits:
BasicObject
Defined in:
lib/gorillib/utils/console.rb

Overview

An inspecting delegator.

Create a trap passing in any object of your choice.

Any time a method is called on the trap, it prints the method name, all its args, and the direct caller.

Examples:

Did you know how basic operators work? Now you do!


trapped_int = ItsATrap.new(3)

trapped_int - 55
[:-, [55], nil, "..."]
=> -52

55 - trapped_int
[:coerce, [55], nil, "..."]
=> 52

- trapped_int
[:[email protected], [], nil, "..."]
=> -3

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(meth, *args, &block) ⇒ Object (private)

Any time a method is called on the trap, it prints the method name, all its args, and the direct caller.

#==(*args, &block) ⇒ Object

These are defined on BasicObject, delegate them along with the rest BasicObject.instance_methods => [:==, :equal?, :!, :!=, :instance_eval, :instance_exec, :send, :id]

# File 'lib/gorillib/utils/console.rb', line 46

def ==(    *args, &block)        ; __describe_and_send__(:==,     *args, &block) ; end

#__obj__ ⇒ Object

Returns the proxied object.

Returns:

  • the proxied object

def __obj__ ; @obj ; end

#equal?(*args, &block) ⇒ Boolean

Returns:

  • (Boolean)

#inspect ⇒ Object Also known as: pretty_inspect

We implement to_s and inspect, because otherwise it's annoyingly noisy. :pretty_inspect makes pry happy.
