A high performance Data compression utility for the Commodore Amiga
Amiga user interface and compression code by Stefan Boberg
Original 80x86 LZHuf code by Haruyasu Yoshizaki
PRE-RELEASE V0.99c
===========================================================================
Ok, so here it is, the fully Intuitionized, FAST! LhArc compression tool
for the Commodore Amiga, this is only a pre-release so there's no real
documentation yet. It is 100% compatible with LhArc version 1.13c (MSDOS)
and Amiga LhArc (The Italian CLI version), only it is MORE than TWICE as
fast !!! I hope you will understand how to use it anyway, but here's some
tips to get you going:
EXTRACTING
If you want to extract files from an existing archive, first select 'Open
Archive' from the Project menu or press Right-Amiga+O or just press 'O'.
Then select the file from the file requester by entering the source
directory in the Dir gadget and then click twice on the file you want to
extract from, or enter the file's name in the File gadget and press RETURN.
Then click on the files you want to extract (clicking once selects,
clicking a second time deselects again), or use the 'Mark all', 'UnMark
all' and 'Mark...' gadgets. The 'Mark...' gadgets allow you to enter an
ARP-pattern mask to select certain files. (For example. '*.c' will select
all files ending in '.c' and 'a*z' will select all files that begin with an
'a' and end with a 'z', detailed explanations of the pattern matching
functions will be in the final documentation). When you have marked
(highlighted) all files you want to extract, click on the 'Extract' gadget.
Now you will be asked where to put the extracted files, select a directory
and click on the 'OK' gadget. Now LhArcA will extract your files! If you
want LhArcA to consider extended filenames, select 'Extended filenames' in
the Settings menu.
CREATING AN ARCHIVE
When you want to create a new archive, select 'New archive' in the Project
menu, then enter the destination directory and archive name. NOTE: In
this pre-release you must append '.lzh' after the filename, otherwise
LhArcA cannot open it for extraction! This will be fixed in the final
release. Then do just like you do when you add files to an existing
archive. (Described below).
ADDING FILES TO AN EXISTING ARCHIVE
This is easy, first open the archive as when extracting (see above), then
click on the 'Add files' gadget and then select the files you like to add.
You can select as many files as you like and in as many directories you
like. If you want pathnames to be stored, select 'Extended filenames' in
the Settings menu and then set 'Home directory' to the part of the pathname
that should not be stored. (Not enough space to describe this here, wait
for the final version, it will probably work differently then).
ADDITIONAL NOTES
The final version, there will be all the features found in other archivers
(including PkAZip), and more. LhArcA is FASTER than PkAZip!!! (About
15%), and also more effective. To make it even faster I am working on some
new search algorithms which will (hopefully) be finished until the final
release!!! Also in the final release there will be the option to issue
archiver commands directly from the CLI command line (as Zoo, Arc, LhArc
etc.), my intention is to make a program everybody can use, both novices
and experts. (Though this version may be a little hard to understand, I
will possibly add some online help stuff in the final version). Also it
will be possible to create SFX-archives (self-extracting archives), and
more....
Anyway, if you have any ideas for improvements, or find any bugs (I have
sorted out most of them now, there are (I hope) no serious bugs left, just
some things that need to be more polished). Anyway hope you like this,
because it took be two months to get this far!! If you like it, PLEASE
consider sending me a contribution, look in the About... text for more
details.
SYSTEM REQUIREMENTS:
You'll need:
* Arp.library (Version 39.1 is included in this archive).
* An Amiga with at least 512K of RAM.
* You must have ASSIGNed 't:' somewhere. (Preferably to RAM:, to do this,
enter the command 'ASSIGN t: ram:' before running LhArcA.
INSTALLING
To install LhArcA, extract the files from this archive, then execute the
following commands from CLI:
copy Arp.library to libs:
delete Arp.library
This will move the Arp.library to where it should be.
