How to open a console and ruby a ruby script from ruby?

7rans · 1 July 2006 18:44

I know I can do

system "ruby script.rb"

But I want to open a console to run it in.

Thanks.

you probably want something like

   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

regards.

Windoze equivalent inserted below

   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

system "start cmd /k #{command}"

     end
   end

   console 'date'

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.

Thanks. I'll change that. How does one do this on mac btw?

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
