Okay, one elegant way to do make gems visible to MacRuby in XCode4 is to add environment variables GEM_HOME and GEM_PATH in the "Scheme". If you have ruby 1.9.2 installed via rvm (rvm.beginrescueend.com) as I do, type: >rvm 1.9.2 >rvm info Look for the GEM_HOME and GEM_PATH values, and add these into the Environment Variables table in the Arguments tab of the XCode/Scheme/Edit Scheme dialog (whew!). Then just install whatever gems you need at the command line within rvm. PD Begin forwarded message:

Good suggestion.
macgem install hpricot # installs the gem (apparently) macgem list --local # now shows rake and hpricot as the only two local gems...
After experimentation this appears to be because these are the only two loaded under rvm for ruby 1.9.2. "macgem list --local" is just picking up whatever gems are in the currently selected rvm environment, but not all of these are showing up in XCode.
Code snippet in rb_main.rb:
['rubygems', 'pp', 'rake'].each {|gem| puts "Loading '#{gem}'... #{require gem}" #=> true } system ('macgem list --local')
==>
Loading 'rubygems'... true Loading 'pp'... true Loading 'rake'... true
*** LOCAL GEMS ***

More testing later.

Try using "macgem". All of the MacRuby binaries are prefixed with "mac-" (macruby, macirb, macri, etc.)

I'm past the Hello World tutorial, and want to try something useful but I cannot seem to access my gems from within the XCode/MacRuby environment. rubygems is there, as is pp; but not, for instance hpricot.
$gem list --local ... hpricot (0.8.1, 0.6.164) ... rack (1.0.1) rails (2.3.5, 2.3.4, 1.2.6) ...
Within rb_main.rb:
puts "Loading rubygems... #{require 'rubygems'}" #=> true puts "Loading pp... #{require 'pp'}" #=> true
but
puts "Loading hpricot... #{require 'hpricot'}"
gets me "no such file to load -- hpricot (LoadError)"
Any hints? Do I need to hunt down the full path? _______________________________________________ MacRuby-devel mailing list MacRuby-devel@lists.macosforge.org http://lists.macosforge.org/mailman/listinfo.cgi/macruby-devel
