easy dsl style method generation?

[Roger Pack]

Here's what I wish I could easily do.

Move.from(x).to(y)

and set it up easily, like

class Move
def from(x).to(y)

end
end

Any helpers out there to make this somewhat possible that anyone knows
of?

Much thanks.

Apparently, what you're looking for is something like this:

class Move
def from x
@x = x
return self
end

def to y
raise ArgumentError, "X is not defined!" unless @x
@y = y
# Do your actual move
end
end

In plain english, "from" returns an object on which you can call "to".
I mean, I would just do "def move_from_to x, y" but maybe your way can
be done.. Have fun with the error checking though.
