Hi.
Pattern rules are useful, but in practice, they can
change only the suffix of the target pattern.
Sometimes, I want to change the file prefix as well.
The main purpose is to prepend '.' to the file name
in order to hide less-important files.
For example, like this:
a/b.x --> a/.b.timestamp
p/q/r.x --> p/q/.r.timestamp
Is there a way to achieve this?
Currently, pattern rules can use % just once.
I wish I could do something like this:
%{1}/.%{2}.timestamp : %{1}/%{2}.x
do_something
