h1. Patter
This is Patter(n Ruby).
h2. What?
It's a pattern matching thing for Ruby. It's AWFUL.
h2. How?
h3. Patter macro parser
bc.. $ echo <<. >test.pr
fib(0) is
1
end
fib(1) is
1
end
fib(x) is
fib(x-1) + fib(x-2)
end
puts fib(10)
.
$ ruby parse.rb <test.pr >test.rb
$ ruby test.rb
h3. Include Patter
bc.. $ echo <<. >test.rb
require './patter'
include Patter
fib = Fun.new
fib.when(0){1}
fib.when(1){1}
fib.when(Var) do |n|
fib.call(n-1) + fib.call(n-2)
end
.
$ ruby test.rb
h2. Why?
Clearly the Eldritch horrors are upon us.
