Subject: [PATCH v8 00/10] grep: simplify & delete "init" & "config" code
Date: Tue, 18 Jan 2022 16:55:12 +0100	[thread overview]
Message-ID: <cover-v8-00.10-00000000000-20220118T155211Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v7-00.10-00000000000-20211228T004707Z-avarab@gmail.com>

A v8 re-roll of this series. For context and v7 see:
https://lore.kernel.org/git/cover-v7-00.10-00000000000-20211228T004707Z-avarab@gmail.com

The v7 has not been picked up yet. The ab/grep-patterntype in Junio's
tree is the v6. This v8 is rebased on "master" for a merge conflict
with the now-merged lh/use-gnu-color-in-grep.

Ævar Arnfjörð Bjarmason (10):
  grep.h: remove unused "regex_t regexp" from grep_opt
  log tests: check if grep_config() is called by "log"-like cmds
  grep tests: add missing "grep.patternType" config tests
  built-ins: trust the "prefix" from run_builtin()
  grep.c: don't pass along NULL callback value
  grep API: call grep_config() after grep_init()
  grep.h: make "grep_opt.pattern_type_option" use its enum
  grep.c: do "if (bool && memchr())" not "if (memchr() && bool)"
  grep: simplify config parsing and option parsing
  grep.[ch]: remove GREP_PATTERN_TYPE_UNSPECIFIED
