I looked at Ruby Shoes recently http://shoooes.net/ as I think it
would be very nice to have a Plasma Shoes script engine. It is a very
simple GUI toolkit with a DSL that is quite similar to the above. For
instance, here is a complet Shoes program to animate some text moving
about:
Shoes.app do
stack :top => 0.5, :left => 0.5 do
para "Counting up:"
l = para "0"
animate(24) do |i|
f = ['Arial 14px', 'Serif 34px', 'Monospace 18px', 'Arial 48px'][rand(3)]
l.replace "#{i}", :font => f
end
motion do |x, y|
Shoes.p [x, y]
end
end
end
I was thinking of just trying to get existing Shoes apps to run as as
applets, but i get the feeling that it could also be a really good fit
with the KInetic way of doing things.
