From 7a5edbdb748f58c0ff3f2a459596ad6ddfda0640 Mon Sep 17 00:00:00 2001 From: Taylor Blau Date: Sun, 1 Oct 2017 22:25:24 -0700 Subject: [PATCH] ref-filter.c: parse trailers arguments with %(contents) atom The %(contents) atom takes a contents "field" as its argument. Since "trailers" is one of those fields, extend contents_atom_parser to parse "trailers"'s arguments when used through "%(contents)", like: %(contents:trailers:unfold,only) A caveat: trailers_atom_parser expects NULL when no arguments are given (see: `parse_ref_filter_atom`). This is because string_list_split (given a maxsplit of -1) returns a 1-ary string_list* containing the given string if the delimiter could not be found using `strchr`. To simulate this behavior without teaching trailers_atom_parser to accept strings with length zero, conditionally pass NULL to trailers_atom_parser if the arguments portion of the argument to %(contents) is empty.
