DATA.readlines in an inner file

ruby-talk

Is there any way to use DATA.readlines to read the data (below
__END__) in a file that's been required/included? I want the read
code to be inside the included/required file.

i don't think one can do it directly, but:

     harp:~ > cat b.rb
     require 'dynaload'

     module M
       def your_code_here_as_normal
       end
     end

     #
     # add this to the end of the file
     #
     data = open(__FILE__)
     data.each{|line| break if line =~ /^__END__$/}
     Dynaload::export data, "name" => "DATA"

     __END__

     harp:~ > cat a.rb
     require 'dynaload'

     loaded = Dynaload::dynaload "b.rb"

     obj, desc = loaded.objects.select{|obj, desc| desc['name'] == 'DATA'}.first

     puts obj.read

Thanks much, was hoping there was a more elegant solution. I was just
going to use it to avoid a 'here doc' block. Now, the 'here doc'
doesn't look so bad :wink:
