Stuffit Engine Implementation
Date: 30.05.02 18:58 (Thu, 30 May 2002 10:58:56 -0700)
From: Jason Brown
Has anyone gotten Aladdin Systems' Stuffit Engine to work directly with
their RB apps? I tried reading the documentation, but i am still having
trouble... any help would be GREAT! or TIPS! Thanks! Below is a sample of
how to use the engine... if i could get assistance on converting it to RB
that would also be helpful:

The following snippit shows how to open and close the Engine, along with
testing its' version:

--begin code sample---

long magicCookie;
OSErr error;
short version = 0;

error = OpenSITEngine( kUseExternalEngine, &magicCookie );

if ( error =toErr )
version = GetSITEngineVersion( magicCookie );

if ( error = oErr && version >= kFirstSupportedEngine )
{
// We found the engine and opened it successfully!
// Do your stuffing and unstuffing operations here...

// When we're done, close the Engine. Once we do this, our
// "magic cookie" is no longer valid!!

CloseSITEngine( magicCookie );
}
else
{
// Some error occurred; handle it here
}

--end code sample---

I tried and made a plugin.
But it doesn't work. Seems like you need a code from Aladdin to activate
this libraries.
Can someone confirm it or may I have a problem?

I wrote a plugin and so did Seth Willits. It works great and it was
pretty easy to do. But I'd need to send $100 to Aladdin to release the
plugin. Actually, I wasn't planning to release the plugin I was planning
to release an app that used the plugin. But I think I need to pay $100
for that as well. And I'm betting that even if you do it with declares
(which, I have to admit, is kind of an interesting idea) you'd still
need to give Aladdin $100 to distribute the result.

I disagree, if OS X is concerned.

Expander is free, so there's no problem.

Or did I get something wrong? Is the goal to stuff or to unstuff via RB?

Right. I wanted to call the Stuffit Engine from within an RB app.
Actually, the RB app I had in mind was something onto which you drop a
folder and get an opportunity to include and exclude files before you
stuffed it. I actually have it working, but I can't, as far as I can
tell, distribute it. It was going to be free, but Aladdin doesn't seem
to care about that.

I've noticed that an increasing number of software distributions for OS X is
actually in dmg or even in zip format, read: does not rely on SIT.

Perhaps Aladdin better reconsiders it's licensing terms...

Hopefully,

Yes the goal is to ONLY stuff using a RB app... however, a good point was
brought up in the fact that I might be able to use ZIP instead because
EXPANDER will unzip a zipped file... theres an idea.. can anyone point me in
the right direction for zipping then? thanks!

From: Didier Barbas
I wrote a small app, that is basically a shell wrapper to OpenSSL, Zip and
Tar/gzip. I have problems with tar right now (no idea why), so this part has
been yanked out until the problems are fixed. There is a problem with
zipping files that have a resource fork (the resource fork won't be taken
into account), so I want to add some kind of hqx support (maybe based on
base-64, since openSSL has it too) for those files.
I'll release a beta soon (early June) with source.

Why can't hearing aids be configured with regExes?
preg_replace (/(([bullshit])([good stuff]))*/, / \\3/);
Huh?

Sit is smaller than all of them in my experience.

Not to mention that OS X 10.1.4 won't mount external disks, or disk images.

What do you mean it won't? The Disk Copy utility mounts disk images for you!
A lot of apps are distributed via disk image. So why are you saying you
can't use them with OS 10.1.4?

Nothing but my hard drive mounts since upgrading to 10.1.4. I dunno, maybe

Re: Stuffit Engine Implementation

From: Seth Willits
Seeing as how I wrote a plugin that implements almost every aspect of the
StuffIt Engine I guess I'll write about it.

My plugin does almost everything, it stuffs in a million formats, unstuffs
every format, does some stuff with text files, archives, I think password
protection, the list goes on. Anything it doesn't have, I can add.

My plugin is available from the Freak Software store. The fee I charge you
is for the plugin. HOWEVER, YOU WILL HAVE TO GET A LICENSE FROM ALADDIN TO
USE IT IN YOUR APPLICATION. Now, if I had the money, I would buy a license
and badda bing badda boom, no one but me would have to register it.

(Aladdin's licensing scheme is very screwy)

So anyway, yeah you can do whatever with it for my fee and if you want to do
it the legal way, theirs.

The plugin can be downloaded from

Well, how about this: Ask the first person who's willing to register it with
Aladdin to instead send you the money so you can register it for everyone.

According to my experiences, it depends on the type of file you're
compressing. All in all, I think it's safe to say that the differences are
negligible.

Well, I have the money but am not willing to spend it. I'd love to make the
plugin available to everyone, but I'm not going to spend $250 and not get
anything or very little back. There are simply better things to buy like RB
4.5, new manuals, CW8, a new computer, and Deus Ex for PS2.

Stinks, but that's life for me.

If everyone on the list donated a buck I'd end up with atlest 3 times as
much money as I needed.

1 person = $250
5 persons = $50
10 persons = $25
25 persons = $10
50 persons = $5
and the list goes on.

The fact is not enough people are interested in adding any kind of
compression to their applications.

Are you saying that there is a plug-in somewhere that does zip
archives?? I've been searching (and asking on this list every now and
again) for something like this for quite a while. I could use something
that creates zip archives on OS 8.6-9.2. Right now I've solved the
problem by embedding an applescript that talks to ZipIt, but I'd sure
like something faster.

What is a zip archive? Is it just a folder with zlib applied to it? If
so, that shouldn't be too hard to turn into a plugin.

Not quite - it's a serialized stream containing zlib'd versions of
each of the files plus a header for each file with some information,
as well as a global central directory with information of all the
files in the archive and their offsets in the stream attached to the
end of the .zip file.
The spec is actually open (I forgot where I saw it, but try Google)
and can probably be implemented even in native realbasic even if one
had a way to access zlib (there are many versions of shared libs and
dlls of zlib available, or you can use einhugur's excellent plugins).

Hope this helps,

Not Zip Archives, but I have Zip Compression and CRC32 for this in my
MBS Plugin. The format of the Zip file archive format is available in
the web so you might put both together.

Seth,

My understanding is that the zip source code is more or less available
and free (I'd have to look up where to get it, though). If you want a
less costly compression option, maybe you could look into it.

I know we Mac people are very attached to .sit files, but pc people
don't seem to know what they are (and I'm talking educated pc people,
who write and sell programs).

A plug-in that can create a .zip archive (not a .Z file, that you can
get with zlib) would be cross platform (because we can open it with
stuffit and they can open it with whatever it is they open .zip files
with). I would think that would make it worth more to some people than a
stuffit plug-in might be worth.

Just a thought.

Tamara

You *can* open it with Stuffit. I'd forgotten about that. That is pretty
cool.
