Creating a ZIP archive purely in memory?

Rails
1

Has someone devised a way to create a ZIP archive purely in memory? I
know of rubyzip, but apparently it can only create an archive as a
file. That’s not too bad, but if I can I’d prefer to do this in memory.

Out of curiosity, why?

If you want to work around it, you can mount a ramdisk and zip to a
file in that… or perhaps look at FuseFS
(http://rubyforge.org/projects/fusefs/) if you want to roll your
own…

Alternatively you could just use ZLib, but I assume you want zip for a
reason…

Cheers!

I guess he’s dynamically generating a zipfile for his users to download.

e.g. download all posts from the past month.

Exactly. Doing this in memory and then send_data’ing would just be more
convenient than creating a temporary file and using send_file on it.

Did anyone ever come up with a way of doing this (other than using
chilkats zip library)?

Thanks
