Subject: Administrivia

  Welcome to the alt.sources.mac digest.  Currently, I am
the moderator of the archive.  I thought I would post this
message to show everyone what has been accumulating at the
archive site.

  Your contributions are highly recommended and accepted.
If you don't have access to the alt.sources.mac newsgroup,
you can email your contribution to me ([e-mail])
and I will add it to the archive, or you can upload it to
the /ftp/pub/incoming directory at the archive site.

  I would also recommend to those programmers posting
snippets to the comp.sys.mac.* heirarchy to also crosspost
them to the alt.sources.mac group so that I can make sure
that it gets added to the archive.

  A couple of notes that you might want to be aware of:
    1.  Been doing alot of moving with the archive lately, currently
        the root for all files is /Bio Mail Server/ftp/..., but this
        is only temporary.
    2.  The archive has lots of Frequently Asked Questions in the
        /ftp/pub/mac-faqs directory, including the round of sillyness
        which encompased the FAQs-as-application phase (these files
        are located in the /ftp/pub/mac-faqs/sillyness directory ;-)
    3.  The debate still rages on concerning the Layer Manager
        (fortunately I have been avoiding the flames ;-) but I have
        not received any complaints about keeping the Layer Manager
        header file in the archive, so it still remains there.
    4.  The alt.sources.mac archive is going to be mirrored at
        mac.archive.umich.edu (or am I mirroring them?  ;-)  Actually
        I am one of the new archivists at mac.archive, and one of
        the main reasons I wanted to come aboard was to get the
        alt.sources.mac archive to a site that's alittle more
        dependable than mine (can you say "System Error..." ;-)
        so hopefully everything can get taken care of soon (I
        have to do some modifications to my index files first), but
        I am still planning on keeping ftpbio up and running, at
        least for the short term.

  Thanks for your support, and if you have any questions,
problems, or maladjustments, feel free to email me.  Also, let
me know if you have any problems accessing the archive.  The only
way I can fix things is if I am told... ;-)

I think what you're talking about is called "A2Hex"; it's part of the
MPW Script Tips package on the Developer CD (and on ETO, I think).
Here's a copy of it; because it's relatively long for an MPW Script,
I BinHexed it rather than convert all the high-bit characters to
7-bit equivalents.

It doesn't output in a "prototype" format, but it's easy to convert
the output or the script to give you what you want.

Enjoy;

Subject: Append-c

This is a .c file I got off Oakland's ftp, which I've gotten to run on
Think C 5.0.4.

It puts up SFGetFile, propting for 'TEXT', and you select one.  Then it
repeats this cycle until you select Cancel.  Each time after the first
time, it copies and pastes the contents at the end of the first files.
Doesn't make a new file, doesn't ask if you want to do this - it just
does it.

Here's a repost of the package. The previous upload included objects,
which made it unnecessary large, and when I tried compiling it, its
memory settings were messed up. No major problems, but it's better this
way. It now requires Think Pascal 4, though it's easy to re-create a
v3 project if you need it.

Subject: CircularWDEF-c

That's right, folks!  A round window WDEF.  Has goAway and growBox!  It's
B/W, but a little creative hacking, using Infinity as a guide, coult make
it into a jewel.

Probably the best use for a round window would be a splash screen, in
which case a plain one, or a "dialog-looking" one would be optimum.

It would not take too much effort to modify it into the notorious
"diamondWDEF" I've heard of (but not seen).

I didn't write this, nor do I recall where I got it.  but all I had was
the .c file, so I neatened up the code appearencewise, build a WDEF with
it, tossed in "WDEFTester" so you could easily check it out, then
packaged it up for "shipping."

Enjoy!

Subject: Dimmable Dialog Text Items Source

Here is some pretty useful code that I'm posting with the author's
(Jim Walker <[e-mail]>) permission.  It allows you
to dim statText and editText items in a dialog without any extra
dialog items, etc.  A demo application is included.  The code is free;
author requests any updates and enhancements.  To use the "Dim_text()"
function, your dialog can't be using the refCon field or QuickDraw
bottleneck. (Not a big deal, IMHO).  Real "gray" is used if it's
available.

There is a funny bug that I reported to Jim that turned out to be in
the Dialog Manager.  If a dialog contains two or more editText items
that contain more text than fits in the rect, and you force the
dialog to update (by temporarily covering it with another dialog,
for example) then only the item containing the insertion point will
update correctly; the others will have text missing.

To see this behavior in the enclosed demo application, enter
"Hello world!" in one of the editText items, dim it, and only "Hello"
will be displayed (but will be dimmed!)  Un-dimming it returns it
back to displaying "Hello world" (with the exclamation point being
the part not fitting).  Anyone have any ideas on how to fix this?

Subject: DropFTP

Enclosed is DropFTP and source. A drag and drop ftp program based on
dropshell. FTP code was taken from Newswatcher and merged with drop shell.

Currently it sends the files as if it they are text files. If anyone has
some c code for macbinary encoding I would like to see it.

Default strings are stored in STR#1000. User string are stored in the
pref file with the password scrambled as in NW. Password in the
dialog box is not hidden. If any strings are left empty it will
bring up the dialog box before the files are sent.

Error reporting is not fully  done. It might bring up an empty dialog box
on some errors.

I forgot to include a way to specify a directory but that pretty
trivial and will be in the next version. So will password hidding.
If all goes well so will MacBinary encoding.

I forgot to change the BNDL to include folder dropping. I think dropshell
supports folder dropping.

Have fun Hacking.

Xavier

P.S. if you make any changes I would like to see them too.

This was an occasionally requested file, in c.s.m.p, which demo's pie
chart, bar chart, graph chart, etc. in Think C.  has a built library (as
I recall) but also has ALL the demo .c files added to the project.  For a
quick-start, you'll need to remove all but one of the files with "demo"
in its name.  The lib., too, if you get multipy defined link errors.
Don't know why it was shipped this way.  All I did to it was change it
from compactor to Stuff It.  There's plenty of docs with it.

Yep, I have written a sample DarkSide module for use with Think C
(I used DarkSide 4.2 and Think C 5).
I have rewritten FaderShell for use with Think C. The main changes
were the A4/A5 stuff, and also some routines which used MPW C syntax
had to be modified.
The fader is called Morpion, it shows the computer playing against itself
the game of Morpion (the first player which manages to align five markers
on the grid wins).
You can use the source code freely.

Subject: OvalsDooDadd 1.1 dscr.

This is a Think C 5 project for the new guys.  There are actually two,
here.  They are derivatives of an old 1985 MegaMax C source file called
"Display" - available on Oakland's FTP.

OvalsDoodadd 1.1 put's up a splash screen in a Rect in the main window,
using centered strings and various text faces and sizes for 4 seconds.
Then it erases and 4 scroll bars and a button are drawn.  Menu has Apple
(with about) and File with quit.

The scroll bars all start at min. and control the vertical and horizontal
quanities of ovals drawn down to center, with another set for the amount
of offset.

So, at max quantity and offset of one, it's solid.  It's in B/W.

The control procs are from EartPlot.

It's heavily, and entertainingly, commented.

I cleaned up the original "Display" file and put a TC 5 project to it,
and it runs.  Beyond that I did little else.

You'll easily spot where the oval thing came out of it.

Subject: SpriteManager-c

This is the SpriteManager I got off AOL a couple years ago.  I added the
Think C 5 project, did enough updating to get it to compile and run, but
it still needs a little debugging.  It was probably a TC 4 project,
originally.

Puts up two windows, side by side.  Animates an 'ICN#' in one, inverting
trails as it goes.  The other one is supposed to have a drag-able sprite
in it, like the demo, but doesn't work.  But HEY!  I can't do everything!
Gotta save something for the downloader!

Tony Miles credited SpriteManager in his SpriteWorld documentation.

Subject: Re[2]: A REALLY GOOD Random Number Generator

I worked for quite a while to write a good, fast implementation of
Marsaglia's Ultra RNG.  This is a compound generator comprised of a
Fibonacci generator and a feedback-shift generator and is *reportedly* the
best general-purpose RNG currently available.

My library is written in Think C/Assembly for a 68020/68881 (or better).
[The algorithm is very cumbersome in pure C.]

The library contains 16 functions to return random numbers of various
kinds, including exponential and Gaussian variates, as well as functions to
save and restore the RNG context (for repeating a sequence).  On a Mac II
ci, a random Boolean takes 1.6 microseconds and a random Gaussian 50.5
microseconds.
