NAME
xfdDecrunch 1.08
SYNOPSIS
xfdDecrunch SOURCE/A,DEST,ALL/S,FORCE/S,CLONE/S,
ND=NODIRS/S,NA=NOASK/S,LS=LINKSIMPLE/S,
LP=LINKPRO/S,CA=COPYALL/S,SH=STRIPHUNKS/S,
NE=NOEXTERN/S
DESCRIPTION
xfdDecrunch unpacks crunched files. It requires either
Kickstart V37+ or the arp.library together with older
releases of the OS.
SOURCE specifies the file(s) that should be decrunched.
Wildcards of any kind are supported.
DEST is the file/drawer to save the result to.
If SOURCE contains wildcards/is a drawer, DEST must be
a directory. If it doesn't exist, it will be created.
If SOURCE is a single file, DEST can be an existing
directory or a (new) filename. In the first case, the
old filename will be used in the new directory.
Without DEST, the old files will be overwritten.
Files that cannot be decrunched will usually not appear
in the DEST drawer. COPYALL tells xfdDecrunch to simply
copy all these files to the DEST drawer too. Certainly
this option only works if DEST is given.
ALL makes xfdDecrunch go through all subdirectories
that exist in SOURCE. Note that these drawers are
created in the same order in the DEST directory.
If there exists a file with the name of a drawer to be
created, files will be written to the parent drawer.
If NODIRS is given, no subdirectories will be created
and files from all drawers will be written to DEST.
If DEST already exists, you will be asked if you want
to overwrite the file. With FORCE, this request will
be skipped.
With CLONE, the decrunched files (and drawers) receive
the same comments and protection bits as the source
files.
Usually, when an error occurs while decrunching a file,
xfdDecrunch asks if you want to continue with the next
files or quit. With NOASK specified, this request will
be skipped and decrunching continues automatically.
With files that are crunched with an absolute address
cruncher, you have two additional options: LINKSIMPLE
and LINKPRO. The first one links a quite simple header
to the decrunched data that simply copies the file to
the required location and executes it. The second
header is more complex. It tries to allocate the wanted
memory area and works with overlays thus not needing
any memory at all before allocating the desired area.
This is absolutely system-friendly and should work
even on machines with less RAM.
Sometimes it may happen that you get a crunched file
that is decrunch-protected with an additional hunk
linked somewhere in front of or after the decrunch
header of the file. With STRIPHUNKS, you can remove
name, symbol and debug hunks from the file, giving
you a better chance to finally decrunch that file.
NOEXTERN prohibits the use of external slaves for
recognition and decrunching. This is very useful for
files that crash your machine everytime they are tried
to be decrunched, for example SFX files.
HISTORY
xfdDecrunch 1.08
- Added NOEXTERN option.
xfdDecrunch 1.07
- Fixed xfdFreeObject() call. Some bytes have not been
released correctly. Thanks to WEPL for the hint.
- Fixed problem with single '*' wildcard. This was not
interpreted as '#?', but as the current Shell window.
This actually is a DOS problem, but replacing a '*'
internally with '#?' fixes the problems. Thanks to
Holger Wessling for the hint.
- Fixed problems with empty files. They caused the
stupid 'Not enough memory' error. Now they are
reported as 'Empty file'.
xfdDecrunch 1.06
- Fixed 'Continue after error?' request. If there
aren't any more files after the error occured,
you won't get that request any longer.
- Fixed problem with empty files and COPYALL option.
Now empty files are created in the destination
drawer too. Thanks to Axel Folley for that hint.
xfdDecrunch 1.05
- Added option STRIPHUNKS.
- xfdmaster.library v36+ is required now.
xfdDecrunch 1.04a
- Debugged some arp.library stuff.
xfdDecrunch 1.04
- Added decrunch support for files that are locked
with 16/32 bit keys.
- Special hello to all Kickstart 1.2/1.3 users.
Yes, it works again. Re-added full arp.library
support for the old Kickstart versions.
- Modified the professional header for address
files a bit for Kickstart 1.2/1.3 support.
xfdDecrunch 1.03
- CLONE doesn't clone the creation dates anymore.
- CLONE now also clones the comments and protection
bits of any drawers that are created.
- Added COPYALL option.
- Added abbrevations for NODIRS and NOASK options.
xfdDecrunch 1.02
- Totally removed arp.library and Kick 1.3 support.
It was impossible to implement all OS 2 features.
- xfdDecrunch now creates the same drawer hierarchy
in the destination drawer as given in the source
drawer (with ALL option).
- Source and destination lengths are printed now.
- Added NODIRS and NOASK options.
- Added LINKSIMPLE and LINKPRO options.
xfdDecrunch 1.01
- Fixed bug in CLONE routine. SetFileDate() has been
called on Kick 1.3, but it's not available there!
- Changed some internal stuff for the documented
release of xfdmaster.library 33.2.
xfdDecrunch 1.00
- First public release.
