IO.popen(*command) fails

[bobthecow]

in Ruby 1.9.3 (here: https://github.com/alloy/terminal-notifier/blob/master/Ruby/lib/terminal-notifier.rb#L20 )

Removing the star works:

      IO.popen(command) do |stdout|
        output = stdout.read
        STDOUT.print output if verbose
        result << output
      end

whee!

Awww damn, I thought I had tested that. Thanks!

Hmm, it seems to work for me on 1.9.3-p194. Which version are you on?

[bobthecow]

1.9.3p194.

It works with a string, or with a single-element array. But it fails with multi-element arrays:

IO.popen("echo sup dawg")          # works
IO.popen(["echo", "sup", "dawg"])  # works
IO.popen(*["echo sup dawg"])       # works
IO.popen(*["echo", "sup", "dawg"]) # fails

ArgumentError: wrong number of arguments (3 for 1..2)

This is consistent with the documentation, which says it takes either a string or an array of strings as the first argument.

You’re completely right. Thanks!

Released as 1.4.2

Awesome :)
