Rather than checking homebrew first, honor explicit user preferences by checking the zstyle first, then looking for chruby in its default location, and finally falling back on homebrew only if chruby was not found anywhere else.

# With either a manual or brew installed chruby things should just work.
|
|
#
|
|
# If you'd prefer to specify an explicit path to load chruby from
|
|
# you can set variables like so:
|
|
#
|
|
# zstyle :omz:plugins:chruby path /local/path/to/chruby.sh
|
|
# zstyle :omz:plugins:chruby auto /local/path/to/auto.sh
|
|
#
|
|
# TODO
|
|
# - autodetermine correct source path on non OS X systems
|
|
# - completion if ruby-install exists
|
|
|
|
# rvm and rbenv plugins also provide this alias
|
