PDF::PDF constant causes conflicts

[yob]

htmldoc defines the PDF::PDF constant to be a string that equals 'pdf'.

Unfortunately that means any code inside the root PDF module (like my pdf-reader) that uses the PDF constant gets the string instead of the root module we expect. Can the PDF::PDF constant be renamed to something else?

I just ran into this issue. Is there a workaround that you know of?

Thanks for bringing this to my attention. Can you provide a test case for this to explain what the problem is? Could you maybe do ::PDF as a work-around?

Hey Craig, it appears the htmldoc renders yob's pdf-reader (and possibly Prawn) useless - and vice versa if they're include in the same project.

require 'htmldoc'
require 'pdf-reader'

PDF::Reader.new("somepdf.pdf") #=> TypeError: ”pdf“ is not a class/module

Same issue reported on Stackoverflow:

I forked htmldoc and changed the constant name PDF::PDF and all seems well now.
