From ff01513f45a74d08fdd43f72461800a915e15c90 Mon Sep 17 00:00:00 2001 From: Sohom Datta Date: Thu, 8 Oct 2020 08:36:04 +0000 Subject: [PATCH] userdiff: expand detected chunk headers for css The regex used for the CSS builtin diff driver in git is only able to show chunk headers for lines that start with a number, a letter or an underscore. However, the regex fails to detect classes (starts with a .), ids (starts with a #), :root and attribute-value based selectors (for example [class*="col-"]), as well as @based block-level statements like @page,@keyframes and @media since all of them, start with a special character. Allow the selectors and block level statements to begin with these special characters.
