Clash of RubyZip and PDF::Writer

ruby-talk
1

I'm using PDF::Writer to generate files by the hundreds. My spec
requires that I batch them up into zip files. I thought this would be a
piece of cake, but I appear to have run into a clash. From what I can
read in the documentation, PDF::Writer only has the "save_as" option
available to me, which takes a file name and writes a file out to disk.
However, ZipFile expects me to open up a new file inside it and then
write contents to it. I think that means I have to write out the pdf,
then open it back up and stream its contents into the zipfile object?
That seems like it will be pretty inefficient. Am I missing something -
is there a better way to tie these two libs together?

You're missing something. The implementation of #save_as is:

  def save_as(name)
    File.open(name, "wb") { |f| f.write self.render }
  end

Render is a public method. It isn't documented (surprisingly) on
PDF::Writer, but it does exist.

Perfect!

Thanks for throwing that in, now I don't feel so n00b :slight_smile:
