popen("-") is unimplemented

[pberg]

Still a comment: I use jruby 1.5.2 (latest version) and the problem appears in
lib/pdfkit/pdfkit.rb

in function to_pdf:

def to_pdf
append_stylesheets

pdf = Kernel.open('|-', "w+") # PROBLEM !
exec(*command) if pdf.nil?
pdf.puts(@source.to_s) if @source.html?
pdf.close_write
result = pdf.gets(nil)
pdf.close_read

raise "command failed: #{command.join(' ')}" if result.to_s.strip.empty?
return result

end

Is it possible to fix it to get it work with jruby?

I've pulled in a patch which switches PDFKit to use popen. I've confirmed that it does work with jRuby 1.5.6.

Thanks
