  4. # With either a manual or brew installed chruby things should just work.
  5. #
  6. # If you'd prefer to specify an explicit path to load chruby from
  7. # you can set variables like so:
  8. #
  9. # zstyle :omz:plugins:chruby path /local/path/to/chruby.sh
  10. # zstyle :omz:plugins:chruby auto /local/path/to/auto.sh
  11. #
  12. # TODO
  13. # - autodetermine correct source path on non OS X systems
  14. # - completion if ruby-install exists
  15. # rvm and rbenv plugins also provide this alias
  16. alias rubies='chruby'
