Hello:

This might seem weird, I just started Ruby, so don't know much about it,
HOW CAN I PASS ARGUMENTS AS A STRING FROM A UNIX TERMINAL INTO A RUBY
SCRIPT?

I'm developing an application with REALbasic(why?!, because I already
own a license and with REALbasic I can develop and application that can
run natively on OS X without the need of installing extra
libraries(wxCode, wxRuby, etc(problems with building and deploying)) and
using just the Ruby language installed by default on OS X), I would like
to use also RUBY to process ALL the text that comes from Editfields in
REAL.

I already did this "hello world" test and it's working, at least one
way. In this sample you have a window, an editfield and a pushbutton,
once the pushbutton is pressed, it executes a rubyscript and return its
result to be displayed on the editfield. The REAL code is:

Dim s as New Shell
Dim cmd as String
#if TargetMacOS or TargetLinux and Not( TargetMacOSClassic)
  cmd="cd /Applications/hello-ruby ; ruby hello.rb"
#elseif TargetWin32
  cmd="set"
#endif

s.execute cmd
if s.errorCode=0 then
  EditField1.text=s.Result
else
  EditField1.text="Error "+ Str(s.ErrorCode)
end if


If you are not familiar with REAL, in this sample I'm using a SHELL
class that can be used to execute Unix or DOS shell commands under
Windows, Mac OS X, or Linux, so in the OS X terminal runs [cd
/Applications/hello-ruby ; ruby hello.rb] and inside the ruby script
there is a simple

puts "Hello World!"

which is returned to the editfield in the REAL interface and displayed.
NOW! I would like to make another sample that could work in the other
way also, so let's suppose I have 3 editfields and a pushbutton, in
editfield1 I enter "hello", next in editfield2 "world!", once the button
is pressed the editfield3 displays the result "hello world!" which was
concatenated in a ruby script.

From the Shell class of REAL I would have to send the strings into the
terminal using ECHO, then How I pass them into the ruby script from the
terminal to be processed?
