Isolate – Simple, per-project RubyGem sandboxing
Isolate is a tool for managing RubyGems by including them within the project that requires them. At Goldstar, we recently switched from Bundler to Isolate for managing our gem dependencies.
Though we ended up switching to what I consider to be a technically superior product based on simplicity, we arrived there because of poor community interaction on the part of the Bundler developers.
Isolate, developed by John Barnette, seems to be a less opaque alternative to Bundler where gems are built and installed within a single Ruby project, in a "vendorized" fashion.
Steven's adoption and advocacy of Isolate stems from a bitter and fundamental disagreement between Steven, BJ Clark, and an un-named Bundler developer. Ah, the intrigue!
