From a36a822d7d42f36baf0b3d7a0af5691ce692ce20 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Thu, 16 Jan 2025 13:35:52 -0800 Subject: oddballs: send usage() help text to standard output Using the show_usage_if_asked() helper we introduced earlier, fix callers of usage() that want to show the help text when explicitly asked by the end-user. The help text now goes to the standard output stream for them. The callers in this step are oddballs in that their invocations of usage() are *not* guarded by if (argc == 2 && !strcmp(argv[1], "-h") usage(...); There are (unnecessarily) being clever ones that do things like if (argc != 2 || !strcmp(argv[1], "-h") usage(...); to say "I know I take only one argument, so argc != 2 is always an error regardless of what is in argv[]. Ah, by the way, even if argc is 2, "-h" is a request for usage text, so we do the same". Some like "git var -h" just do not treat "-h" any specially, and let it take the same error code paths as a parameter error. Now we cannot do the same, so these callers are rewrittin to do the show_usage_and_exit_if_asked() first and then handle the usage error the way they used to.
