Mechanize Download File w/o Loading it All in Memory

Is there a way to get Mechanize to download a csv file, without loading
it all into memory first? As I understand even if I used a pluggable
parser, it will still download the whole file into memory before saving
it to a file?

Thanks!

I don’t actually know if this will solve your problem as I’ve not used
it, but this looks like it is on the right track:

require ‘rubygems’
require ‘mechanize’

agent = WWW::Mechanize.new
agent.pluggable_parser.pdf = WWW::Mechanize::FileSaver
agent.get(‘http://example.com/foo.pdf’)

then again, it might not. mechanize doesn’t sound like a very good
tool to be using for csv’s in the first place as it can’t actually DO
much with them. Why not use a more straightforward tool like curl?

It’s a whole process just to get to the page where you can download the
csv file. I have to log in to the site, request the file, etc. which
is why I was hoping I could do it in mechanize
