Issue #10320 has been updated by Nobuyoshi Nakada. So Wieso wrote: > I chose the symbol `:Lib`, as I thought Ruby would complain if the constant `Lib` would not exist at this time. The keyword `in` would define it, ifit would not exist. I would prefer if we could solve it without using symbols, but writing `module Lib; end` before the first require doesn't look nice. It's ambiguous if `Lib` is a module or a class, when only the name is provided. ---------------------------------------- Feature #10320: require into module https://bugs.ruby-lang.org/issues/10320#change-49230 * Author: So Wieso * Status: Open * Priority: Normal * Assignee: * Category: core * Target version: ---------------------------------------- When requiring a library, global namespace always gets polluted, at least with one module name. So when requiring a gem with many dependencies, at least one constant enters global namespace per dependency, which can easily get out of hand (especially when gems are not enclosed in a module). Would it be possible to extend require (and load, require_relative) to put all content into a custom module and not into global namespace? Syntax ideas: ~~~ruby require 'libfile', into: :Lib # keyword-argument require 'libfile' in Lib # with keyword, also defining a module Lib at current binding (unless defined? Lib) require_qualified 'libfile', :Lib ~~~ This would also make including code into libraries much easier, as it is well scoped. ~~~ruby module MyGem require 'needed' in Need def do_something Need::important.process! end end # library user is never concerned over needed's content ~~~ Some problems to discuss: * requiring into two different modules means loading the file twice? * monkeypatching libraries should only affect the module вк auto refinements? * maybe also allow a binding as argument, not only a module? * privately require, so that required constants and methods are not accessible from the outside of a module (seems to difficult) * what about $global constants, read them from global scope but copy-write them only to local scope?
