how do i turn an object into a binding?

[Bret Pettichord]

I have code such as this:

foo.bar
foo.baz(1)
foo.bagaloo('didoo')

instead i want to write it like this:

with (foo) do
bar
baz(1)
bagaloo('didoo')
end

how?

how?

foo.instance_eval do
bar
baz(1)
bagaloo('didoo')
end

 

[Austin Ziegler]

foo.instance_eval do
bar
baz(1)
bagaloo('didoo')
end

Note that this won't work if you try to use assignment, because that
will be interpreted as a local variable. Better:

module Kernel
def with(obj)
yield self if block_given?
end
end

with longfooname do |f|
f.bar
f.baz(1)
f.bagaloo('didoo')
end

True. In this case 'self' could be used:

foo.instance_eval do
self.quux = true
end

If assignment methods haven't yet been defined in a class definition,
the same problem occurs.

Better:

module Kernel
def with(obj)
yield self if block_given?
end
end

with longfooname do |f|
f.bar
f.baz(1)
f.bagaloo('didoo')
end

Well, than you could do f = longfooname at the beginning as well.
