DATA.readlines in an inner file


#1

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.

The best answer to most questions is “it depends”.

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



 harp:~ > ruby a.rb
 42

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:
