Unloading (or unrequiring) a file

Ruby
1

Hey all,

I’m trying to dynamically load parts of code to make things and
methods available.

The catch is that I’d also like to make those things and methods
UNavailable as well (or load something else in place of the original
loaded item).

I know there’s no Kernel#unload, so how can I achieve my goal?

Thanks,
aRi

As far as methods go there’s remove_method and undef_method. For
constants theres remove_const. An idea I’ve had was to fork, although
that’s a little heavy handed

eg:

… code …
pid = fork do
require ‘this_will_go_away’
but_so_will_this_var = ThisWillGoAway.new
but_so_will_this_var.do_something
end

Process.wait pid

p but_so_will_this_var # NameError
