Mac OS X example scripts have the command (directive/statement/?)… ENV[‘BRIDGE\_SUPPORT\_PATH’] = ‘/Volumes/Data/src/svn-rubycocoa-apple/ framework/bridge-support’ I can’t find any write-up of this line anywhere. It’s in RSSPhotoViewer in Developer/Examples/Ruby/RubyCocoa/RSSPhotoViewer/ rb\_main.rb Can someone please explain what this is, what it does, and where it is documented? ---

I’ve never worked on a Mac, but the ENV hash en ruby is a mechanism for accessing environment variables. This: # in ruby ENV[‘PATH’] = ‘/usr/bin’ is equivalent to this: /\* in csh \*/ setenv PATH “/usr/bin” ---

ENV is a Hash-like object (but not a hash) that contains the environment variables of your environment. ENV[‘BRIDGE\_SUPPORT\_PATH’] = ‘…’ sets the environment variable BRIDGE\_SUPPORT\_PATH to ‘…’ for you and all processes inheriting your environment. HTH, Sebastian ---
