fortytwo :~ > cat a.rb
require ‘rbconfig’
require ‘tempfile’

def console command
arch = Config::CONFIG[‘arch’]

 unless arch =~ %r/win/i
   tmp = Tempfile.new Process.pid.to_s
   tmp << command
   tmp << "\n"
   tmp << "bash"
   tmp << "\n"
   tmp.close
   begin
     system "xterm -e 'bash -l -i #{ tmp.path }'"
   ensure
     tmp.close!
   end
 else
   raise 'windoze'
 end

end

console ‘date’

i’ll leave the windoze bit to you :wink:

Beware that you’re technically detecting both windows and mac (darwin)
with /win/. You might want to check for win32 (or, i suppose, win64?)
instead.

Eh, yeah but it’s not ideal (You’ll have to wait for X11 to start
usually, which it may or may not do automatically, I’m not sure. i
think it might if opened via the Finder but not from the command
line).

What I would do is

IO.popen(“osascript”, “w”) do |io|
io.puts <<APPLESCRIPT
tell Application “Terminal”
activate
do script “#{command_here}”
end tell
APPLESCRIPT
end

This has the advantage of not opening a new instance of terminal if
one is already open, (but it will if necessary) and not requiring the
user to a) have X11 installed and b) have it running.

Well, it doesn’t work but not because of terminals not opening. You
have a syntax error in the actual page

io.puts << APPLESCRIPT

should be

io.puts <<APPLESCRIPT # it’s a heredoc
