From 129b3632f35a1c46fb30d9e6f275a95119a9d521 Mon Sep 17 00:00:00 2001 From: "D. Ben Knoble" Date: Sun, 3 Aug 2025 12:10:27 -0400 Subject: builtin: also setup gently for --help-all Git experts often check the help summary of a command to make sure they spell options right when suggesting advice to colleagues. Further, they might check hidden options when responding to queries about deprecated options like git-rebase(1)'s "preserve merges" option. But some commands don't support "--help-all" outside of a git directory. Running (for example) git rebase --help-all outside a directory fails in "setup_git_directory", erroring with the localized form of fatal: not a git repository (or any of the parent directories): .git Like 99caeed05d (Let 'git -h' show usage without a git dir, 2009-11-09), we want to show the "--help-all" output even without a git dir. Make "--help-all" where we expect "-h" to mean "setup_git_directory_gently", and interpose early in the natural place ("show_usage_with_options_if_asked"). Do the same for usage callers with show_usage_if_asked. The exception is merge-recursive, whose help block doesn't use newer APIs. Best-viewed-with: --ignore-space-change Signed-off-by: D.
