Does Mojave still have Ruby 1.8 available?  I have bundle files referencing /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby but that directory does not exist.  I'm not sure how to proceed, since this does break some functionality.

The problem is that many bundle commands need ruby 1.8, so the bundle support code needs to remain compatible with 1.8 as well.

This is support code has been written by a dozen different people over several years, I have no plans of rewriting it all to be compatible with both ruby 1.8 and 2.x, which in itself is not a fun excercise, not even sure we can make the plist extension compatible with both versions of ruby without switching to a version written entirely in ruby.

Understandable. I’ve been wanting to completely re-implement the support code with support for 2.0 now for a while. But I’ve never prioritized it.

My advice: If you want to use ruby 2.x for your custom commands, don’t use the support code.

Yeah, in fact, most of my commands are written in Ruby 2.0 but one of them is using Ruby 1.8 to be able to use the completion window.

In this case I see now that TextMate.detach is simple enough to copy to the bundle and remove the dependency on TextMate::UI.

In retrospect we probably shouldn’t have made a “shared support” directory, at least not without much much stricter discipline, as now we have a ton of legacy stuff that is pretty difficult to get rid of, because we have no idea about which third party bundles rely on it.

The support code, at least the Ruby code, could be implemented as a separate gem. Then it could be versioned like any other gem. I have a bundle [1] where the whole Support directory is organized as a Ruby gem. It uses Bundler and several gems as dependencies. The gems are bundled directly in the Support directory and included in the Git repository. This works out quite nicely.
