Hi,

Currently it is technically "possible" to set a mirror for a gem repo using environment variables. For example, use "BUNDLE_MIRROR__HTTPS://FOO__RUBYGEMS__ORG/" to set a mirror for the repo "https://foo.rubygems.org/". Unfortunately the name of this environment variable is illegal. If I do "export BUNDLE_MIRROR__HTTPS://FOO__RUBYGEMS__ORG/=https://rubygems.org/", I got an error "not a valid identifier". Is it possible to escape the illegal characters here (namely : and /)?

It seems that the spec says the only illegal character is “=“, which we don’t use: http://stackoverflow.com/a/2821183. That said, it might be worth it to see if there’s a way to accommodate implementations that only support [a-zA-z_].

There was a change made in this pull request to allow you to specify credentials in the environment using just the hostname rather than the full URI https://github.com/bundler/bundler/pull/3295

BUNDLE_GEMS__COMPANY__COM=user:pass


It doesn't look like the same pattern is currently supported for mirrors, unfortunately, but maybe someone could submit a pull request to add it?
