Ruby binary temp file

[wimxa]

require 'tempfile'
f = Tempfile.open 'tmp'

will open f in text mode (mode = 'w', not 'wb'). Any non-hacky way to
open this in binary mode? I can, of course, make f, close it and open
it as a real file - it's just this is not atomic.

Not that I can see.

May I suggest file-temp? It opens in binary mode by default:

You can switch it to binary mode after it's open:

#!/usr/bin/env ruby -wKU

require "tempfile"

f = Tempfile.new "binary"
f.binmode # switch to binary mode
