Subject:	ANNOUNCE: DJGPP port of GNU grep 2.13 uploaded.
Date:	Mon, 9 Jul 2012 00:42:21 +0200

This is a port of GNU grep 2.13 to MSDOS/DJGPP.


  This is GNU grep, the "fastest grep in the west".
  GNU grep is based on a fast lazy-state deterministic matcher (about
  twice as fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper
  search for a fixed string that eliminates impossible text from being
  considered by the full regexp matcher without necessarily having to
  look at every character.  The result is typically many times faster
  than Unix grep or egrep.  (Regular expressions containing backreferencing
  will run more slowly, however.)



  DJGPP specific changes.
  =======================

  DJGPP specific changes are those required to implement colorization support
  for this port.  If grep is called with the command line option --color and
  the output is directed to the screen then the default colors will be used
  to mark matches, file names and line numbers.  If the output does not go to
  the screen then colorization is automatically suppressed.  Read the docs to
  learn how to control the color using the environment variable GREP_COLORS.
  As usual all changes are documented in the diffs file that is stored in the
  /djgpp directory.

  Please note that to run the test suite produced with autoconf 2.64 and later
  you must install mktmp17br2 or later.  Because the test suite also tries to
  test multibyte patterns but multibyte strings are not fully supported by
  DJGPP some tests will be skipped or fail.  The yesno test is known to fail,
  so please do not report it.  Before starting the testsuite, please make sure
  to unset the GREP_OPTIONS in djgpp.env or the testsuite may not work as
  expected.

  The grep program uses a new method called fts to traverse a file tree.  This
  code is very posix centric, especially it uses gnulib functions like openat,
  openat-proc and fdopendir that try to access directories using file descriptors
  with open().  This is only supported by djdev204 but not by djdev203.  This
  means that if grep is compiled using djdev203, the program will no longer be
  able neither to recurse directories nor will be able to follow symlinks.
  This is because djdev203 only produces symlinks for programs.  In both cases
  grep will always terminated with ENOSYS.  grep211 was probably the last DJGPP
  port of grep compiled with djdev203.

  This port has been configured with perl-regexp (pcre) support enabled.
  This means that you will have to install pcre libray available as:
    ftp://ftp.delorie.com/pub/djgpp/current/v2tk/pcre830b.zip
  or
    ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/pcre830b.zip
  if you decide to compile the sources.  If you prefer to disable the pcre
  support you will have to reconfigure and recompile the suorces again, but
  this time passing the "no-pcre" command line option to config.bat.
  The grep213b.zip file contains both versions of the grep program, the one
  build without perl-regexp support have the usual name and the one compiled
  with perl-regexp support is called greppcre.exe.  You can install both
  versions or keep the one you prefer and delete the other one.

  This port has no wide character/multi byte support at all.

  To build this port and run the testsuite you will need LFN support.
  Please note that the testsuite also runs a lot of gnulib tests that will all
  fail.  I have no intension to fix them.

  For further information about GNU grep please read the info docs and NEWS file.



  This is an verbatim extract of the NEWS file:
-------------------------------------------------------------------------------
* Noteworthy changes in release 2.13 (2012-07-04) [stable]

** Bug fixes

  grep -i, in a multi-byte locale, when matching a line containing a character
  like the UTF-8 Turkish I-with-dot (U+0130) (whose lower-case representation
  occupies fewer bytes), would print an incomplete output line.
  Similarly, with a matched line containing a character (e.g., the Latin
  capital I in a Turkish UTF-8 locale), where the lower-case representation
  occupies more bytes, grep could print garbage.
  [bug introduced in grep-2.6]

  --include and --exclude can again be combined, and again apply to
  the command line, e.g., "grep --include='*.[ch]' --exclude='system.h'
  PATTERN *" again reads all *.c and *.h files except for system.h.
  [bug introduced in grep-2.6]

** New features

  'grep' without -z now treats a sparse file as binary, if it can
  easily determine that the file is sparse.

** Dropped features

  Bootstrapping with Makefile.boot has been broken since grep 2.6,
  and was removed.


-------------------------------------------------------------------------------


  The port has been compiled using stock djdev203 (patchlevel 2) and consists
  of the usual three packages that can be downloaded from ftp.delorie.com and
  mirrors as (timestamp 2012-07-08):

    grep 2.13 binaries, info and man format documentation:
    ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/grep213b.zip

    grep 2.13 dvi, html, pdf and ps format documentation:
    ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/grep213d.zip

    grep 2.13 source:
    ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/grep213s.zip


  The binaries have been produced a second time using the stock version of
  djdev204 beta library.  This package is available at ftp.delorie.com and
  mirrors as (timestamp 2012-07-08):

    grep 2.13 binaries, info and man format documentation:
    ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/grep213b.zip


  Send grep specific bug reports to <bug-grep AT gnu DOT org>.
  Send suggestions and bug reports concerning the DJGPP port to
  comp.os.msdos.djgpp or <djgpp AT delorie DOT com>.
  If you are not sure if the failure is really a grep failure
  or a djgpp specific failure, report it here and *not* to
  <bug-grep AT gnu DOT org>.

Enjoy.
