Command line rubygems and require

given the file requires_foo.rb

require ‘foo’

class ReqFoo
end

if foo is a gem, then i can run it by going:

ruby -rubygems requires_foo.rb

why can’t i have a file requires_foo2.rb

class ReqFoo
end

and go:

ruby -rubygems -r foo requires_foo2.rb

it’s giving me a LoadError

but maybe i’m approaching the problem wrong. what i’m doing is that i
have a large file which is a tutorial to my lib in rdoc, and which is
doing an :include: of my examples when need be, in order for my example
code to be writen in only one place. the problem is that i don’t want a
whole lot of requires and shebangs and whatnot in the examples. is there
a standard proceedure for this kind of thing? ideas/suggestions for an
rdoc noob? my solution is just to have a little shell script in the
examples directory which goes something like:

ruby -rubygems -r foo example$1.rb

but then there’s the problem listed above.

thanks,

my solution is just to have a little shell script in the
examples directory which goes something like:

ok i’ve rewritten my little shell script in ruby solving my main
problem, but am still curious about the command line procedure.

RubyGems wraps the require command in order to locate the gem
directories during a require. The -r option bypasses the require
command entirely and attempts to load the file without allowing RubyGems
to do its thang.

Sorry.
