From bd958e91dffdba00ef94dc9bfc04b46599362f9a Mon Sep 17 00:00:00 2001 From: Scott Baker Date: Mon, 23 Mar 2026 02:02:15 -0400 Subject: diff-highlight: allow module callers to pass in color config Users of the module may want to pass in their own color config for a few obvious reasons: - they are pulling the config from different variables than diff-highlight itself uses - they are loading the config in a more efficient way (say, by parsing git-config --list) and don't want to incur the six (!) git-config calls that DiffHighlight.pm runs to check all config Let's allow users of the module to pass in the color config, and lazy-load it when needed if they haven't.
