        is put in different compiled structure patterns[]. The patterns
        are given to dfacomp() and kwsmusts() as is.
        (Ecompile): Likewised.
        (Fcompile): Reverse to the old behaviour of compiling the entire
        patterns in one shot.
        (EGexecute): If falling to GNU regex for the matching, loop in the
        array of compile patterns[] to find a match.

        (xrealloc): Removed using lib/xmalloc.c.
        (xmalloc): Removed using lib/xmalloc.c
        (main): Register with atexit() to check for error on stdout.
        * configure.in: Check for atexit(), call jm_MALLOC, jm_REALLOC and
        jm_PREREQ_ERROR.
        * tests/bre.awk: Removed the hack to drain the buffer since we
        always fclose(stdout) atexit.

        * src/exclude.h: New file.
        * src/grep.c (main): Took the GNU tar code to handle
        the option --include, --exclude, --exclude-from.
        Files are check for a match, with exclude_filename ().
        New option --exclude-from.
        * src/savedir.c: Call exclude_filename() to check for
        file pattern exclusion or inclusion.


        * m4/dosfile.m4 (AC_DOSFILE): Move AC_DEFINEs out of AC_CACHE_CHECK.

2001-02-17  Alain Magloire

        * doc/grep.texi: Document the new options and the new behaviour
        back-references are local.  Use excerpt from Karl Berry regex

        (color): Rename color variable to color_option.
        Removed 'always|never|auto' arguments, not necessary for grep.
        (exclude_pattern): new variable, holder for the file pattern.
        (include_pattern): new variable, holder for the file pattern.
        * src/savedir.c: Signature change, take two new arguments.
        * doc/grep.texi: Document, new options.
        * doc/grep.man: Document, new options.



2001-02-09  Alain Magloire

        Patch from Ulrich Drepper to provide highlighting.

        * src/grep.c: New option --color.
        (color): New static var.

        to find the offset of the matching string.
        * src/savedir.c: Take advantage of _DIRENT_HAVE_TYPE if supported.
        * src/search.c (EGexecute, Fexecute, Pexecute): Take a new argument
        when doing exact match for the color highlighting.

        Problem noted by Gerald Stoller <gerald_stoller@hotmail.com>

        * src/grep.c (main): POSIX says that -q overrides -l, which
        in turn overrides the other output options.  Fix grep to

        on pre-OpenVMS 7.x systems; general overhaul.
        * src/getpagesize.h: Reinstate support for different pagesizes on
        VAX and Alpha. Work around problem with DEC C compiler.
        * src/vms_fab.c: Cast to some assignments; fixed typo argcp vs. argp.
        * src/vms_fab.h: Added new include files to avoid warnings about
        undefined function prototypes.
        Those patches were provided by Martin P.J. Zinser (zinser@decus.de).


1999-03-16 Volker Borchert

        * configure.in: Use case ... esac for  checking Visual C++.
        When ${CC} contains options it was not recognize.

1999-03-07 Paul Eggert


1999-02-10 Alain Magloire

        * bootstrap/{Makefile{try,am},README} : skeleton
        provided for system lacking the tools to autoconfigure.

        * src/{e,f,}grepmat.c: added guard [HAVE_CONFIG_H]

        * doc/Makefile.am djgpp/Makefile.am m4/Makefile.am vms/Makefile.am:
        New files.

        * m4/progtest.m4: protect '[]' from m4.
        Noted by Eli Z.

        * PATCHES-AC: New file, add the patch for autoconf in the dist.

        Suggested by Harald Hanche-Olsen.

        * src/grep.c (main): '-f /dev/null' now specifies no patterns
        and therefore matches nothing.
        Reported by Jorge Stolfi.
        Patched by Paul Eggert.


        * src/grep.c: reverse back to greping directories,
        One could skip the error message by defining
        SKIP_DIR_ERROR. There is no clear way of doing
        things, I hope to settle this on the next major release
        Thanks Paul Eggert, Eli Zaretskii and gnits for the
        exchange.


        (setmatcher) [HAVE_SETRLIMIT]: Set re_max_failures so that the
        matcher won't ever overflow the stack.
        (main) [__MSDOS__, _WIN32]: Handle backslashes and drive letters
        in argv[0], remove the .exe suffix, and downcase the program name.
        [O_BINARY]: Pass additional DOS-specific options to getopt_long
        and handle them.  Call stat before attempting to open the file, in
        case it is a directory (DOS will fail the open call for

        regex package. Change the way the tests were done to be more
        conformant to automake.

        * configure.in: added --disable-regex for folks with their own functions.

        * grep-20d : available for testing



        * check.sh, scriptgen.awk: fix grep paths.

        * change the directory structure: grep is now in src to comply with
        gettext.m4.

        * grep.c version.c [VERSION]: got rid of version.c,


        * Version 2.0 released.

* Noteworthy changes in release 3.11 (2023-05-13) [stable]

** Bug fixes

  With -P, patterns like [\d] now work again.  Fixing this has caused
  grep to revert to the behavior of grep 3.8, in that patterns like \w
  and \b go back to using ASCII rather than Unicode interpretations.
  However, future versions of GNU grep and/or PCRE2 are likely to fix
  this and change the behavior of \w and \b back to Unicode again,
  without breaking [\d] as 3.10 did.
  [bug introduced in grep 3.10]

  grep no longer fails on files dated after the year 2038,
  when running on 32-bit x86 and ARM hosts using glibc 2.34+.
  [bug introduced in grep 3.9]

  grep -P no longer fails to match patterns using negated classes
  like \D or \W when linked with PCRE2 10.34 or newer.
  [bug introduced in grep 3.8]


** Changes in behavior

  grep --version now prints a line describing the version of PCRE2 it uses.
  For example, it prints this when built with the very latest from git:
    grep -P uses PCRE2 10.43-DEV 2023-04-14
  or this with what's currently available in Fedora 37:
    grep -P uses PCRE2 10.40 2022-04-14

  previous versions of grep wouldn't respect the user provided settings for
  PCRE_CFLAGS and PCRE_LIBS when building if a libpcre2-8 pkg-config module
  was found.


* Noteworthy changes in release 3.10 (2023-03-22) [stable]

** Bug fixes

  With -P, \d now matches only ASCII digits, regardless of PCRE
  options/modes. The changes in grep-3.9 to make \b and \w work
  properly had the undesirable side effect of making \d also match
  e.g., the Arabic digits: ٠١٢٣٤٥٦٧٨٩.  With grep-3.9, -P '\d+'
  would match that ten-digit (20-byte) string. Now, to match such
  a digit, you would use \p{Nd}. Similarly, \D is now mapped to [^0-9].
  [bug introduced in grep 3.9]


* Noteworthy changes in release 3.9 (2023-03-05) [stable]

** Bug fixes

  With -P, some non-ASCII UTF8 characters were not recognized as
  word-constituent due to our omission of the PCRE2_UCP flag. E.g.,
  given f(){ echo Perú|LC_ALL=en_US.UTF-8 grep -Po "$1"; } and
  this command, echo $(f 'r\w'):$(f '.\b'), before it would print ":r".
  After the fix, it prints the correct results: "rú:ú".

  When given multiple patterns the last of which has a back-reference,
  grep no longer sometimes mistakenly matches lines in some cases.
  [Bug#36148#13 introduced in grep 3.4]


* Noteworthy changes in release 3.8 (2022-09-02) [stable]

** Changes in behavior


  release 2.5.3 (2007), now warn that they are obsolescent and should
  be replaced by grep -E and grep -F.

  The confusing GREP_COLOR environment variable is now obsolescent.
  Instead of GREP_COLOR='xxx', use GREP_COLORS='mt=xxx'.  grep now
  warns if GREP_COLOR is used and is not overridden by GREP_COLORS.
  Also, grep now treats GREP_COLOR like GREP_COLORS by silently
  ignoring it if it attempts to inject ANSI terminal escapes.

  Regular expressions with stray backslashes now cause warnings, as
  their unspecified behavior can lead to unexpected results.
  For example, '\a' and 'a' are not always equivalent
  <https://bugs.gnu.org/39678>.  Similarly, regular expressions or
  subexpressions that start with a repetition operator now also cause
  warnings due to their unspecified behavior; for example, *a(+b|{1}c)
  now has three reasons to warn.  The warnings are intended as a
  transition aid; they are likely to be errors in future releases.

  Regular expressions like [:space:] are now errors even if
  POSIXLY_CORRECT is set, since POSIX now allows the GNU behavior.

** Bug fixes

  In locales using UTF-8 encoding, the regular expression '.' no
  longer sometimes fails to match Unicode characters U+D400 through
  U+D7FF (some Hangul Syllables, and Hangul Jamo Extended-B) and
  Unicode characters U+108000 through U+10FFFF (half of Supplemental
  Private Use Area plane B).
  [bug introduced in grep 3.4]

  The -s option no longer suppresses "binary file matches" messages.
  [Bug#51860 introduced in grep 3.5]

** Documentation improvements

  The manual now covers unspecified behavior in patterns like \x, (+),
  and range expressions outside the POSIX locale.


* Noteworthy changes in release 3.7 (2021-08-14) [stable]


I was changing it anyway I decided to do a general cleanup.

3	* Noteworthy changes in release ?.? (????-??-??) [?]	3	* Noteworthy changes in release 3.11 (2023-05-13) [stable]
		4
		5	** Bug fixes
		6
		7	With -P, patterns like [\d] now work again. Fixing this has caused
		8	grep to revert to the behavior of grep 3.8, in that patterns like \w
		9	and \b go back to using ASCII rather than Unicode interpretations.
		10	However, future versions of GNU grep and/or PCRE2 are likely to fix
		11	this and change the behavior of \w and \b back to Unicode again,
		12	without breaking [\d] as 3.10 did.
		13	[bug introduced in grep 3.10]
		14
		15	grep no longer fails on files dated after the year 2038,
		16	when running on 32-bit x86 and ARM hosts using glibc 2.34+.
		17	[bug introduced in grep 3.9]
		18
		19	grep -P no longer fails to match patterns using negated classes
		20	like \D or \W when linked with PCRE2 10.34 or newer.
		21	[bug introduced in grep 3.8]
		22
		23
		24	** Changes in behavior
		25
		26	grep --version now prints a line describing the version of PCRE2 it uses.
		27	For example, it prints this when built with the very latest from git:
		28	grep -P uses PCRE2 10.43-DEV 2023-04-14
		29	or this with what's currently available in Fedora 37:
		30	grep -P uses PCRE2 10.40 2022-04-14
		31
		32	previous versions of grep wouldn't respect the user provided settings for
		33	PCRE_CFLAGS and PCRE_LIBS when building if a libpcre2-8 pkg-config module
		34	was found.
		35
		36
		37	* Noteworthy changes in release 3.10 (2023-03-22) [stable]
		38
		39	** Bug fixes
		40
		41	With -P, \d now matches only ASCII digits, regardless of PCRE
		42	options/modes. The changes in grep-3.9 to make \b and \w work
		43	properly had the undesirable side effect of making \d also match
		44	e.g., the Arabic digits: ٠١٢٣٤٥٦٧٨٩. With grep-3.9, -P '\d+'
		45	would match that ten-digit (20-byte) string. Now, to match such
		46	a digit, you would use \p{Nd}. Similarly, \D is now mapped to [^0-9].
		47	[bug introduced in grep 3.9]
		48
		49
		50	* Noteworthy changes in release 3.9 (2023-03-05) [stable]
		51
		52	** Bug fixes
		53
		54	With -P, some non-ASCII UTF8 characters were not recognized as
		55	word-constituent due to our omission of the PCRE2_UCP flag. E.g.,
		56	given f(){ echo Perú\|LC_ALL=en_US.UTF-8 grep -Po "$1"; } and
		57	this command, echo $(f 'r\w'):$(f '.\b'), before it would print ":r".
		58	After the fix, it prints the correct results: "rú:ú".
		59
		60	When given multiple patterns the last of which has a back-reference,
		61	grep no longer sometimes mistakenly matches lines in some cases.

13		75
		76	The confusing GREP_COLOR environment variable is now obsolescent.
		77	Instead of GREP_COLOR='xxx', use GREP_COLORS='mt=xxx'. grep now
		78	warns if GREP_COLOR is used and is not overridden by GREP_COLORS.
		79	Also, grep now treats GREP_COLOR like GREP_COLORS by silently
		80	ignoring it if it attempts to inject ANSI terminal escapes.
		81
		82	Regular expressions with stray backslashes now cause warnings, as
		83	their unspecified behavior can lead to unexpected results.
		84	For example, '\a' and 'a' are not always equivalent
		85	<https://bugs.gnu.org/39678>. Similarly, regular expressions or
		86	subexpressions that start with a repetition operator now also cause
		87	warnings due to their unspecified behavior; for example, *a(+b\|{1}c)
		88	now has three reasons to warn. The warnings are intended as a
		89	transition aid; they are likely to be errors in future releases.
		90
		91	Regular expressions like [:space:] are now errors even if
		92	POSIXLY_CORRECT is set, since POSIX now allows the GNU behavior.
