Re^2: pp only to create executable when source has changed (pseudocode)

[LanX]

Sorry but

    if (-m $source > -m $exe) {

where do I find the docs of this -m function?

UPDATE:

     while (my ($source, $exe) = keys %files) {

did you really mean keys? not each?

         my ($source, $exe) = splice(@ARGV, 0, 2);

and now your directly overwriting the loop vars?

[muba]

You raise valid points. -m should have been -M, keys should have been each, and that splice line shouldn't be there at all. My bad.

Thanks for pointing me to -M, I didn't know that it exists.

OTOH it's practically useless because it only counts in days, it's very hard to imagine a valid usecase!

(Beside maybe log-rotation on a daily basis)

forget my last remarks, wrong tests indicated complete days, but actually floats are fine!
