Subject: ANNOUNCE: DJGPP port of GNU Sed 4.2.2 uploaded.
Reply-To: djgpp AT delorie DOT com

This is a port of GNU Sed 4.2.2 to MSDOS/DJGPP.


   sed is a stream editor. A stream editor is used to perform basic text
   transformations on an input stream (a file or input from a pipeline).
   While in some ways similar to an editor which permits scripted edits
   (such as ed), sed works by making only one pass over the input(s), and
   is consequently more efficient. But it is sed's ability to filter text
   in a pipeline which particularly distinguishes it from other types of
   editors.

   Please, read carefully the NEWS file to see the user visible changes
   and read the info or html docs to become familiar with the program.
   For beginers the chapter: examples in the info doc may be instructive.
   The chapter: Other resources for learning about 'sed' contains pointers
   to usefull sed specific urls.



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

   - The input stream is switched to binary mode, if it does not come 
from the
     console, on platforms, like DOS/WIN95, that distinguish between 
text and
     binary files. This will allow to process files that contain embedded ^Z
     and lone ^M characters.
   - 8+3 valid file names will be generated for backup names of input 
file names
     if only SFN support is available.  This concerns the '-i' option 
(in-place
     editing).
   - To compile the sources, unistd.h and the popen/pclose functions 
from the
     CVS repository are used.
   - No support for DJGPP's own regex function.  They no longer do match 
the GNU
     regex ones.  Here some work needs to be done before DJGPP's 
functions will
     again be a one-to-one substitute of GNU regex.
   - The tst-pcre, tst-boost and tst-rxspencer tests have been excluded 
from the
     testsuite because they require getline() to be compiled.  DJGPP 
does not
     offer this function.  All other 79 tests will successfully pass.

     As usual, all djgpp specific files (config.bat, diffs, readme 
files, etc.)
     are located in the /djgpp subdir.



   Here is an extract of the NEWS file showing the user visible changes from
   the last port (sed 4.2.1) to this one:

Sed 4.2.2

* don't misbehave (truncate input) for lines of length 2^31 and longer

* fix endless loop on incomplete multibyte sequences

* -u also does unbuffered input, rather than unbuffered output only

* New command `F' to print current input file name

* sed -i, s///w, and the `w' and `W' commands also obey the --binary option
   (and create CR/LF-terminated files if the option is absent)

* --posix fails for scripts (or fragments as passed to the -e option) that
   end in a backslash, as they are not portable.

* New option -z (--null-data) to separate lines by ASCII NUL characters.

* \x26 (and similar escaped sequences) produces a literal & in the
   replacement argument of the s/// command, rather than including the
   matched text.

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


   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 2013-02-05):

     Sed 4.2.2 binary, info and man format documentation:
     ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/sed422b.zip

     Sed 4.2.2 dvi, html, pdf and ps format documentation:
     ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/sed422d.zip

     Sed 4.2.2 source:
     ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/sed422s.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 2013-02-05):

     Sed 4.2.2 binary, info and man format documentation:
