Subject: [PATCH v3 5/6] ref-filter.c: use trailer_opts to format trailers
Date: Sat, 30 Sep 2017 17:10:36 -0700 [thread overview]
Message-ID: <20171001001037.23361-5-me@ttaylorr.com> (raw)
In-Reply-To: <20171001001037.23361-1-me@ttaylorr.com>
Fill trailer_opts with "unfold" and "only" to match the sub-arguments
given to the "%(trailers)" atom. Then, let's use the filled trailer_opts
instance with 'format_trailers_from_commit' in order to format trailers
in the desired manner.

Additionally, the trailers as interpreted by linkgit:git-interpret-trailers[1]
are obtained as `trailers` (or by using the historical alias
-`contents:trailers`).
+`contents:trailers`). Non-trailer lines from the trailer block can be omitted
+with `trailers:only`. Whitespace-continuations can be removed from trailers so
+that each trailer appears on a line by itself with its full content with
+`trailers:unfold`. Both can be used together as `trailers:unfold,only`.
For sorting purposes, fields with numeric values sort in numeric order
(`objectsize`, `authordate`, `committerdate`, `creatordate`, `taggerdate`).
