Subject: [PATCH 1/2] pretty.c: refactor trailer logic to `format_set_trailers_options()`
Date: Sat, 05 Sep 2020 19:48:10 +0000 [thread overview]
Message-ID: <4180f54c1de51a3b9e29ef42b035bb31215875e3.1599335291.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.726.git.1599335291.gitgitgadget@gmail.com>
From: Hariom Verma <hariom18599@gmail.com>
Refactored trailers formatting logic inside pretty.c to a new function
`format_set_trailers_options()`.
Also, introduced a code to get invalid trailer arguments. As we would
like to use same logic in ref-filter, it's nice to get invalid trailer
argument. This will allow us to print accurate error message, while
using `format_set_trailers_options()` in ref-filter.
