[ruby-core:55211] [ruby-trunk - Feature #8465] Proc set_binding

From: "beanstalksurf (Jacob Burkhart)" <igotimac@...>
Date: 2013-05-31 01:40:58 UTC
List: ruby-core #55211
Issue #8465 has been updated by beanstalksurf (Jacob Burkhart).


Oops, I meant that last line to say:

#I expect...
foo_putter.set_binding(FooFoo.new.foo_foo_proc.binding)
foo_putter.call("blah")
#to output:
# foo blah

----------------------------------------
Feature #8465: Proc set_binding
https://bugs.ruby-lang.org/issues/8465#change-39571

instance_eval is a solution to evaluate a proc in the binding of another object

but it is not a solution for a Proc that takes arguments

I propose that in order to suppor this use-case we need <#Proc>.set_binding

Example:


class BarFoo
  def foo(arg)
    "bar #{arg}"
  end
  def puts_a_foo
    Proc.new do |arg|
      puts self.foo(arg)
    end
  end
end

class FooFoo
  def foo(arg)
    "foo #{arg}"
  end
  def foo_foo_proc
    Proc.new{}
  end
end

foo_putter = BarFoo.new.puts_a_foo

foo_putter.call("blah")
# bar blah

FooFoo.new.instance_eval(&foo_putter)
#foo #<FooFoo:0x007ff0b903f9b0>

foo_putter.binding.eval("puts self.foo('blah')")
# bar blah

FooFoo.new.foo_foo_proc.binding.eval("puts self.foo('blah')")
# foo blah

#I expect...
foo_putter.set_binding(FooFoo.new.foo_foo_proc.binding)
foo_putter.call("blah")
#to output:
# foo foo
