incorrect use of popen3 on Windows

[ghazel]

ArgumentError (wrong number of arguments (7 for 3)):
  yui-compressor (0.9.1) lib/yui/compressor.rb:60:in `popen3'
  yui-compressor (0.9.1) lib/yui/compressor.rb:60:in `compress'
  yui-compressor (0.9.1) lib/yui/compressor.rb:102:in `streamify'
  yui-compressor (0.9.1) lib/yui/compressor.rb:59:in `compress'

I know exec() takes either a string or an array of args, but popen3() on Windows does not seem to. This is easily fixed by calling .join(' ') on the array.

I also get this error on windows under 1.8.7 (1.9 doesn't seem to have this problem). Also figured out the fix just like ghazel though it took me awhile. I changed the initialize block, adding flatten.join(' ') similar to ghazel. Full method:

def initialize(options = {}) #:nodoc:
  @options = self.class.default_options.merge(options)
  @command = [path_to_java, "-jar", path_to_jar_file, *(command_option_for_type + command_options)].flatten.join(' ') 
end

We're using POpen4 as of version 0.9.6. Please reopen if this is still an issue.

Thanks for revisiting this issue. I'm way beyond ruby 1.8.7 now but perhaps ghazel or others can test 1.8.7 and POpen4. I've had no problems with ruby 1.9.1 or 1.9.2 and ruby-yui.

yui-compressr 0.9.6 works great on ruby 1.8.7 on Windows! Thanks!
