From 1c3b05170a02adf894a33bc888b0fb730ee7f236 Mon Sep 17 00:00:00 2001 From: =?utf8?q?SZEDER=20G=C3=A1bor?= Date: Fri, 19 Aug 2022 18:04:02 +0200 Subject: [PATCH] builtin/commit-graph.c: let parse-options parse subcommands MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 'git commit-graph' parses its subcommands with an if-else if statement. parse-options has just learned to parse subcommands, so let's use that facility instead, with the benefits of shorter code, handling missing or unknown subcommands, and listing subcommands for Bash completion. Note that the functions implementing each subcommand only accept the 'argc' and '**argv' parameters, so add a (unused) '*prefix' parameter to make them match the type expected by parse-options, and thus avoid casting function pointers.
