Fascinating. Creating a windows shortcut didn't really
work, but it made me realize that #!/usr/bin/env ruby
wasn't what caused ruby to be invoked. It was the .rb
file association on Windows. (God, I'm slow today.)
Changing the file associations for .rb and .rbw causes
the correct interpreter to be invoked, which is rather
helpful.
Unfortunately, it's not yet a total solution:
> therush.rb
therush.rb:7:in `require':
no such file to load -- history (LoadError)
> echo %RUBYOPT%
rubygems
It looks as though the RUBYOPT environment variable isn't
doing the right thing, so the history.rb isn't being
found. I'm sure it's my problem, at this point. But I'm
once again at a loss to see what the problem is.

If you softlink jruby to ruby and put it higher in the path than C

Good thought. But I'm afraid I was far more stupid
than that. I was executing therush.rb, which contains
#!/usr/bin/env ruby
So the C Ruby gems-library reader was being invoked. (Doh!)
I wonder. Might it be possible to redirect such scripts
so they automatically run under JRuby, instead? (I'd
rather not have to edit downloaded scripts to make them
work.)
