From 9e52a36794552b77ecf26f7f34b226d096978f1e Mon Sep 17 00:00:00 2001 From: Eli Schwartz Date: Wed, 14 Mar 2018 23:13:31 -0400 Subject: makepkg: use the `declare` builtin when backing up variables to eval Rather than manually crafting foo_backup in a loop and eval'ing them with a complicated escape pattern, store every splitpkg_overrides element into a single variable via the eval-friendly `declare` builtin. An alternative to eval would be using `printf -v` but this does not work for arrays. This has the additional benefit of reducing the number of variables/arrays floating around in the environment.
