Module: Gibbler::Block

Includes:
Object
Included in:
Proc
Defined in:
lib/gibbler.rb

Overview

Return the digest for class:arity:binding, where:

  • class is the current class name (e.g. Proc)

  • arity is the value returned by Proc#arity

  • value of lambda? if available (Ruby 1.9) or false otherwise

This method can be used by any subclass of Proc.

NOTE: This is named “Block” because for some reason if this is named “Proc” (as in Gibbler::Proc) and the Rye library is also required, a runtime error is raised (Ruby 1.9.1 only):

undefined method `new' for Gibbler::Proc:Module
/usr/local/lib/ruby/1.9.1/tempfile.rb:169:in `callback'
/usr/local/lib/ruby/1.9.1/tempfile.rb:61:in `initialize'
/Users/delano/Projects/opensource/rye/lib/rye.rb:210:in `new'
