Subject: [PATCH v2 19/20] builtin/stash.c: let parse-options parse subcommands
Date: Fri, 19 Aug 2022 18:04:10 +0200 [thread overview]
Message-ID: <20220819160411.1791200-20-szeder.dev@gmail.com> (raw)
In-Reply-To: <20220819160411.1791200-1-szeder.dev@gmail.com>
'git stash' parses its subcommands with a long list of if-else if
statements. parse-options has just learned to parse subcommands, so
let's use that facility instead, with the benefits of shorter code,
and listing subcommands for Bash completion.
Note that the push_stash() function implementing the 'push' subcommand
accepts an extra flag parameter to indicate whether push was assumed,
so add a wrapper function with the standard subcommand function
signature.
Note also that this change "hides" the '-h' option in 'git stash push
-h' from the parse_option() call in cmd_stash(), as it comes after the
subcommand. Consequently, from now on it will emit the usage of the
'push' subcommand instead of the usage of 'git stash'. We had a
failing test for this case, which can now be flipped to expect
success.
