How do I set Windows-related file attributes in ruby?

Question

How do I tell ruby to create files with the attributes FILE_ATTRIBUTE_TEMPORARY and FILE_FLAG_DELETE_ON_CLOSE?

Answer 1

I grepped Ruby 1.8.7 source and did not find any mention of those attributes, so I'm thinking that you get to fix it and build from source...

Answer 2

You can call Windows functions using the Ruby win32api library. See these examples. It's painful, but it works.

Answer 3

Probably because of it's Unix roots, Ruby doesn't (yet) allow that. You can probably obtain the result you want with:

require 'tempfile'
Tempfile.new "my_temp_file" do |f|
  #...
end
