This is a client for xadmaster.library to enable UnArc to extract 7-Zip
archives.
It supports PPMd (on OS4, 68k build has partial support), BZip2, LZMA, LZMA2 and
Copy (no compression) methods with BCJ and BCJ2 filters. Other methods may be
supported in future, please send me any unsupported archives.
Note that hook functions (eg. clicking "stop" in UnArc) don't work currently,
and the compressed size is not decoded.
If you want a default icon, copy def_7zip.info to envarc:sys, and add the
following to DefIcons:
Filetype: 7zip
Match: 7z\xBC\xAF'\x1C
Please report any bugs to chrisunsatisfactorysoftware.co.uk
A big thank you to Dag ?gren for his rewritten PPMd decoder, without which the
PPMd compression method would not be possible.
Thanks to Stephan Rupprecht for some pointers on creating OS4 native XAD
clients, and to Philippe Bovier for testing the 68k version. The def_7zip icon
is by Martin Merz (www.masonicons.de), the others are 256 colour icons by Ken
"Ken's Icons" Lester.
HISTORY
2.4 (18.09.2010) EIGHTH RELEASE
- Now aborts if an error is encountered writing uncompressed data
2.3 (26.06.2010)
- Use SDK PPMd code on 68k version only
- Reduce stack usage (still too high for 68k, exercise caution)
2.2 (02.04.2010)
Updated to LZMA SDK 9.12 BETA
- Uses SDK PPMd code - not fully working (BCJ2 works, nothing else does),
however this partial PPMd does work on 68k.
2.1 (07.09.2009) SEVENTH RELEASE
Updated to LZMA SDK 9.07BETA
- Now supports LZMA2 compression
OS4 version compiled with latest SDK.
Thought it was appropriate to bump version to 2 as LZMA SDK has had a massive 5
version bump :)
1.9 (05.02.2009) SIXTH RELEASE PPMd compression supported - Unfortunately this
is OS4 only currently as my 68k build gets stuck in a loop when starting the
PPMd decoder. Recompiled with latest SDKs and compilers.
1.8 (02.11.2008) FIFTH RELEASE
Updated to LZMA SDK 4.60BETA
OS4 version can now page to disk on OS4.1+ allowing extraction of large files.
1.7 (04.07.2008) FOURTH RELEASE
Updated to LZMA SDK 4.58BETA (speed optimisations)
Updated to libbz2 1.0.5 (68k build only)
1.6 (03.07.2008)
Converted to newlib and sobjs (OS4 only)
1.5 (09.03.2008) THIRD RELEASE
BZip2 method added.
1.4 SECOND RELEASE
Now extracts the the datestamp of compressed files.
1.3
An order of magnitude faster! An archive which reportedly took 1hr40 with v1.1
extracts in less than a minute with v1.3.
1.2
Added a bit of error reporting, will no longer create empty files instead of
reporting an error. First 68k version.
1.1b
Screwed up the archive last time and the required files weren't in it, please
re-download.
1.1a
Re-release without the required header stripped off the binary (oops)
Also recompiled with optimisations.
1.1 (LZMA SDK 4.57)
first release
