proc-to-lambda

Introduction

Convert proc to lambda, retain the context.

Install

gem install 'proc-to-lambda'

Usage

You can use the method directly by invoke the method to_lambda of ProcToLambda.

my_proc = proc { return self + 1 }
my_lambda = ProcToLambda.to_lambda(my_proc)

# `return` works here, and can retain `self`
1.instance_exec(&my_lambda) # => 2

Or, you can include or extend the ProcToLambda module.

include ProcToLambda

def foo
  to_lambda(proc {})
end

# beware, this is risky.
Proc.extend(ProcTolambda)

Proc.to_lambda(proc {})
