Let’s expand the experimental `--list-cmds`[1] to allow users and programs to query for this information. We will also use this in an upcoming commit to implement `is_deprecated_command`. [1]: Using something which is experimental to query for deprecations is perhaps not the most ideal approach, but it is simple to implement and better than having to scan the documentation Acked-by: Patrick Steinhardt Helped-by: Patrick Steinhardt Signed-off-by: Kristoffer Haugsbakk Signed-off-by: Junio C Hamano --- diff --git a/Documentation/git.adoc b/Documentation/git.adoc index 743b7b00e4..a2f0838b16 100644 --- a/Documentation/git.adoc +++ b/Documentation/git.adoc @@ -219,7 +219,8 @@ If you just want to run git as if it was started in `` then use List commands by group.
