I like this method, however you cannot select text, or paste text from your
clipboard.
That is why I was using the edit_box, but this is what I was going for, as
far as updating text as you type.

Shoes.app  do
tagline "English <=> Albhed!\n", :align => "center"
 para("English:\n")
   @line = para
stack {
 para("Albhed:")
  @line2 = para
}
   @line.cursor = -1
  @line2.cursor = -1
alb={'a'=>'y', ...} #The hash

   keypress do |k|
     case k
       when String, "\n"
         @line.text += k
 @line2.text += alb[k]
       when :backspace
         @line.text = @line.text[0..-2]
 @line2.text = @line2.text[0..-2]
       else
     end
   end
 end

It works very well, for every key I press, the normal text is displayed,
and on another line the 'translated' text.
I did this, and this is so far closest to a command line example I made:

##English <=> Albhed Translator!
##Made with Ruby Shoes!

Dir.mkdir("logs") unless File.exists?("logs")

Shoes.app :width => 410, :height => 350 do

eng={'y'=>'a', ..."} # Alb2Eng

alb={'a'=>'y', ...} # Eng2Alb

tagline "English <=> Albhed!\n", :align => "center"

para("English:\n")
 @eng = edit_box :width => 400
 stack {
para("Albhed:")
  @alb = edit_box :width => 400
 }
 button "Convert" do
  if @eng.text.size > 0 && @alb.text.size > 0
   alert("Remember to Clear!")
  else
    @alb.text.each_line do |line|
    line.each_char do |a|
     @eng.text += eng[a]
    end
    end
    @alb.text = ""
     @eng.text.each_line do |line|
     line.each_char do |e|
      @alb.text += alb[e]
    end
   end
  end
end
 button "Clear" do
  @eng.text = @alb.text = ""
 end

 button "Save" do
  if @eng.text.size == 0
   alert("No Text in English Form! Cannot Save to Log!")
  else
   if @alb.text.size == 0
    alert("No Text in Albhed Form! Cannot Save to Log!")
   else
    if @alb.text.size == @eng.text.size
     time=Time.new

     f = File.new("logs/Eng2Alb_Trans.html", "a")
     f.syswrite("\n\n<center><h2>############### #{time.strftime("%m-%d-%Y
%H: %M:%S")} ###############</h2></center>\n")
     f.syswrite("<b>English:</b>\n")
     f.syswrite("<font color='Red'>")
     f.syswrite @eng.text
     f.syswrite("</font>\n")
     f.syswrite("<hr>\n")
     f.syswrite("<b>Albhed:</b>\n")
     f.syswrite("<font color='Blue'>")
     f.syswrite @alb.text
     f.syswrite("</font>")
     f.close
     alert("Text Saved to Translation Log!")
    else
     alert("Somethings not right...")
    end
   end
  end
 end
 button "Log" do
  system("start Eng2Alb.html")
 end
end

Problem is, it doesn't do line breaks,
So if I go

"This .....[enter]
... and then this!"
It will only do the first line, and that's it.
I tried to 'each_line do |line|' wrapped outside of 'line.each_char do |e|'
it doesn't spit out any errors at me, and will still 'translate' the first
line, but not the others...

I would like to make a standalone application using shoes. Currently I 
have my script which works, a modified version that works with the shoes 
application, but I want to make it so that folks using Windows (I'm on Mac
OS X) can use it as a standalone application. From an earlier thread folks
here mentioned I needed to use rake to do that since the packager has some
issues. Is there a tutorial on how to use rake to build standalone shoes 
apps? 

Wayne

There isn't. This is on my to-do list. I don't even know all the
details of how it works.

What I _do_ know is that you need a app.yml file in your main
directory, and that you can type 'rake APP=path/to/the/app && rake
installer APP=path/to/the/app' to make it build. This is what I do for
Hackety. You can see the app.yaml here:
https://github.com/hacketyhack/hacketyhack/blob/master/app.yaml

I have the following statement in my ruby script: 

ball_map.sort_by!

When I run the script with the shoes GUI wrapped around it, I get an error
in Windows (somebody about method not defined or something like that). 
When I run the same script in Mac OS X, it works. If I run the script 
minus shoes in Windows it also works as expected. Anybody heard of this? 
Why would it work in Mac OS X, but not Windows (both XP and 7)? Very odd. 

Wayne

Had a similar issue, was the encoding of the contents of the array, try 
enforcing encoding UTF16

Hi Wayne,

Umm,... strange.
Could you show us the code?
I'd like to run that on my Windows 7.

ashbb

Oops, I forgot that sort_by! method is supported since ruby 1.9.2.
But Shoes 3 (0.r1514) for Windows includes ruby 1.9.1.

ashbb

Well, then that might be the issue! ;) 

is sort_by available in 1.9.1 ? 

Wayne

Yes!
So, try out the following (replace line 148 in parse_cvs.rb).

ball_map = ball_map.sort_by { |a| [a.pin_alpha.size, a.pin_alpha,
a.pin_number.to_i] }

Hi Richard,

> it doesn't spit out any errors at me
Ah,... try to open the Shoes console window.
I guess you will get some error messages.

Good idea! But seems to need a little bit more. ;-)
Try out the following:

   @eng.text.each_line do |line|
     line.each_char do |e|
       @alb.text += (alb[e] or e)
     end
   end

You'll translate all lines. ;-)

ashbb

I like this, because if it can't pass through the hash, it goes straight on
through.

I'm trying to work on one that handles multibyte characters, I can get A
= Ψ [a greek letter] but I can't get Ψ = A because it reads byte by byte
and not the single character. How would I begin to handle that?

Hi Richard,

Umm,...
In Ruby 1.9, each_char() method can handle a single character.
Shoes 3 includes Ruby 1.9.1. So, Shoes 3 should handle multibyte characters.

Try out the following snippet. But you may have to choose a right font for
your environment.

  Shoes.app do
   ed = edit_box
   button 'print' do
     ed.text.force_encoding('UTF-8').each_line do |line|
       line.each_char do |c|
         @slot.append{para c, font: 'MS UI Gothic'}
       end
     end
   end
   @slot = flow
  end

ashbb

Ah, needed to force encode, that is a much simpler fix!
Now I have a two way multibyte character 'translator'
More like a substitution cipher, but yeah.
