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.
