Many thanks for looking that up for me. Your example works OK for me, 
but when I try to access a local file nothing happens (no error either). 
The code I am using is as follows :-

     pdf.Output('example2.pdf')
     urlName = File.expand_path('example2.pdf')
     alert urlName
     visit "file:///" + urlName

The alert shows the correct full path to my pdf, which I can open 
manually OK. I have tried with both Firefox and Internet Explorer as my 
default browser with the same result. Am I doing something silly with 
the URL - I have a feeling I am doing something basic wrong! Any help 
much appreciated!

Hi Roger,

Try out the following. ;-)

Shoes.app do
   button 'open pdf' do
     system '"C:/Program Files/Mozilla Firefox/firefox.exe" ./example.pdf'
   end
end

Thanks ashbb - I'd already tried that and it worked fine as did a couple 
of other variations such as  :-
   system("start example2.pdf")
and
  shell = WIN32OLE.new('Shell.Application')   # windows only!
  shell.ShellExecute('example2.pdf')

The latter was better as it did not open a console window.

What I was trying to do was to find a way of opening the pdf which was 
cross-platform ie I could distribute my software and have it work on any 
OS etc it was installed on, hence my reason for playing with Launchy and 
trying the 'visit' command to open my pdf.
Thanks
Roger

Oh, I see.
Thank you for sharing your work. I've learned a lot.
Let's continue enjoying Shoes. ;-)

Thanks - but I still haven't resolved my problem - can I open a local 
pdf using visit?

Hi Roger,

> can I open a local pdf using visit?
Sorry, I think it's not possible.
Because Shoes only judges by the header 'http|https', not 'file://' for now.

ashbb

OK - thanks for that.

Roger,

 Instead of debugging all the ways Shoes visit and launchy won't work
(there are many edge cases for each that will fail) write a shoes
alert/window/dialog thingy that defaults to  'system (start ..)' for
Windows, 'system (open ...)' for OSX and for linux you can default to
system (gnome-open...) That covers 95% of the audience. Also allow the
user to browse for the App they want to use to open a .pdf and then
you've got 100%. Twenty lines of Shoes code?

Shoes is funny or liberating in that way. There is often a simple user
written GUI solution when you re-think about the problem in a different
way.
