Is it possible to specify multiple targets from a single source?

Basically I have a binary foo
that generates 1.bar
, 2.bar
and 3.bar
. So I wrote a rule
rule(/[1-3]\.bar/ => [ 'foo' ] do |t|
sh "foo"
end
But if I rake
something that needs all 3 outputs, foo
gets executed 3 times. My problem is that foo
is kind of slow, so executing it 3 times is annoying. Is there a way to make rake only run it once? If not, would it be possible to implement it?
I think the relevante Make concept is Grouped Targets.
