Yosemite filter code...

driven · 6 Nov 2014, 00:17

in case it's of use to anyone else, this is the simplest filter I found...

 if  %x(sw_vers -productVersion).split('.')[1].to_i > 9
    puts 'we have Yosemite, good to go'
  else
    UI.messagebox( "This code works only for Yosemite " )
  end

EDIT: added a needed split...

For Windows:
v = %x[ver].split.last.to_f

5.1 = XP
6.0 = Vista
6.1 = Win7
6.2 = Win8

hi dan,

what's the windows cmd for merging two folders?

on the mac I'm using

 def ditto(source, target)
   %x(ditto "#{source}" "#{target}")
 end

Use ditto to Copy Files & Directories Intelligently from the Mac Terminal

cheers dan,

I've got a migration plugin I keep updating on each release, and with Ruby 2 it's became so simple I just wondered if PC's could use it as well...

I only bother with bring the last version forward to the 'approved' folders...

can I PM you it, to have a look?

xcopy - but on windows a blank cmd window flashes (annoyingly) up on the screen.
I had nothing but issues trying to use xcopy from Ruby., so I gave up.

I prefer to use WIN32OLE and Windows Scripting Host's FileSystemObject.CopyFolder()
[MSDN: FileSystemObject.CopyFolder()](http://msdn.microsoft.com/en-us/library/xbfwysex(v)

require("win32ole")
fso = WIN32OLE.new("Scripting.FileSystemObject")
fso.CopyFolder( "#{source}/*", "#{target}" )

.. because for older Ruby 1.8 on Win there is only 1 binary ("win32ole.so ") to pack along with your plugin.

Or for Ruby 2.0+ and more Unix-like, cross-platform, use the Ruby Standard library:
Ruby Doc: FileUtils::cp_r


require("etc") # binary
require("FileUtils") # rb
FileUtils;;cp_r( "#{source}/.", "#{target}" )

which probably calls something like this on OSX:
out = %x(cp -R -P -p "#{source}/","#{target}/")
Apple Dev: cp man page

EDIT: The snippets above should really be wrapped in begin .. rescue blocks since they do File IO. Notify user of progress, errors, etc.
