+ harbout/contrib/hbzlib
+ added support for zlib library and zip files (based on
minizip)
+ harbour/contrib/hbzlib/zconf.h
+ harbour/contrib/hbzlib/zlib.h
+ zlib include files
+ harbour/contrib/hbzlib/zip.h
+ harbour/contrib/hbzlib/unzip.h
+ minizip include files
+ harbour/contrib/hbzlib/ioapi.c
+ harbour/contrib/hbzlib/zip.c
+ harbour/contrib/hbzlib/unzip.c
+ minizip source files. Some fixes are applied to avoid compile
time warning and errors, see readme.txt for list
; I've compiled with BCC only, please, check other compilers
+ harbour/contrib/hbzlib/hbzlib.c
+ zlib wrapper functions. Przemyslaw Czerpak is author of this code.
The file was posted to developers mailing list on 2007-05-17.
I think licence statments in the begining of file gives permission
to include it into SVN.
* HB_UNCOMPRESSLEN() function added. Source copied from Przemyslaw's
email on 2008-01-10.
+ harbour/contrib/hbzlib/hbmzip.c
+ wrapper functions for minizip library
Function names uses convention:
- HB_ZIP*() - manages compression of .zip file:
HB_ZIPOPEN(), HB_ZIPCLOSE()
- HB_ZIPFILE*() - manages compression of files inside .zip:
HB_ZIPFILECREATE(), HB_ZIPFILEWRITE(), HB_ZIPFILECLOSE()
- HB_UNZIP*() - manages decompression of .zip fileL
HB_UNZIPOPEN(), HB_UNZIPCLOSE()
- HB_UNZIPFILE*() - manages decompression of files inside .zip
HB_UNZIPFILEOPEN(), HB_UNZIPFILEREAD(), HB_UNZIPFILECLOSE(),
HB_UNZIPFILEFIRST(), HB_UNZIPFILENEXT(), HB_UNZIPFILEPOS(),
HB_UNZIPFILEGOTO(), HB_UNZIPFILEINFO()
Parameters of functions are documented inside source files.
+ implemented some higher level functions. These function are not
wrapper of minizip:
HB_ZIPSTOREFILE(), HB_UNZIPEXTRACTCURRENTFILE()
; minizip gives low level access on zip files. This could be a
problem if you not going to put your fingers on internals, but
just want to compress/decompress files. Because managing of
file attributes is a little complicated. These higher level
functions do the job.
; please test code under linux. Source is written using docs only,
without test or deeper knowledge.
+ harbour/contrib/hbzlib/hbzlib.ch
+ defines for zlib and minizip libraries
; I've used HB_ZLIB_* and HB_ZIP_* prefixes, because some original
names of minizip library are too general, ex., APPEND_STATUS_CREATE
If you want to use original define names we change this.
+ harbour/contrib/hbzlib/readme.txt
* some comments on the source of libraries and ChangeLog for minizip
files
+ harbour/contrib/hbzlib/tests/myzip.prg
+ harbour/contrib/hbzlib/tests/myunzip.prg
+ tiny compression/decompression utilities written in Harbour
+ harbour/contrib/hbzlib/Makefile
+ harbour/contrib/hbzlib/make_b32.bat
+ harbour/contrib/hbzlib/make_vc.bat
+ makefiles written using another contrib's makefiles as template
; I'm not makefiles guru, please test it. I've also used command line
parameters: -DNOCRYPT -DNOUNCRYPT, to compile minizip. I don't know
howto include these to our makefiles
