From 2f8b3ea662269e5f8e05228eb7a816606559ca23 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Thu, 4 Aug 2022 18:28:30 +0200 Subject: [PATCH] help.c: refactor drop_prefix() to use a "switch" statement" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Refactor the drop_prefix() function in in help.c to make it easier to strip prefixes from categories that aren't "CAT_guide". There are no functional changes here, by doing this we make a subsequent functional change's diff smaller. As before we first try to strip "git-" unconditionally, if that works we'll return the stripped string. Then we'll strip "git" if the command is in "CAT_guide". This means that we'd in principle strip "git-foo" down to "foo" if it's in CAT_guide. That doesn't make much sense, and we don't have such an entry in command-list.txt, but let's preserve that behavior for now. While we're at it remove a stray newline that had been added after the "return name;" statement.
