From c0a4df688c2844794485709e82a0b821e2a32741 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Wed, 10 Jul 2024 20:38:36 +0100 Subject: trees: use wrapper for dry-running make commands instead of using lots of if/else conditions, do that once and set a variable, dry, to : if not doing a dry run, the variable is empty. prefix this variable in places where you don't want a certain action to be performed, on dry runs. more specifically, : does *nothing* and always returns with zero status (success). this results in cleaner code, and a small sloccount reduction.
