Hi guys and gals--
Perhaps this is a well-known phenomenon, but not only did I not
know of it, I got bitten by it twice (Fool me once, shame on you; fool me
twice, shame on me). Well I not only tracked it down again, I checked
it out on a (nearly) virgin copy of Workbench 1.2 without the assemblage
of PIPE:'s, morerows modified system-configurations, virtual disks,
and other garbage I usually have napping inside my machine, and which make
hunting down the source of a problem like this so much fun. My system is
just a vanilla Amiga 1000 with Commodore's internal expansion to 512K, and
one external Commodore 3.5 drive, so at least I didn't have to worry to
much about add-ons.
So try this experiment (comments are indented):
1) Have available a disk containing SetFont 1.1 (written with Andy Finkel's
help, sorry I can't remember the name of the other author) and a fonts
directory containing the necessary files for Pearl (namely, Pearl.font and
Pearl/8) or some other fixed width font of the same size.
I would be interested in hearing about the results with other fonts
whether of the same size or not, whether of fixed width or not, but I am
trying to eliminate as many variables as possible. If there is a later
version of SetFont, I am unaware of it. Perhaps the problem goes away.
1) Make a new copy of WB 1.2, boot up on it, and kill the startup-sequence
with ^D. Use Preferences (don't worry, its OK) to select 80 characters
per line instead of 60. Save you way out of Preferences.
This may not be necessary, but was appropriate for the font with which I
was testing (namely Pearl/8).
2) Reboot and kill the startup sequence again.
3) Assign fonts: to the fonts directory on the other disk.
4) Run SetFont --> name_of_other_disk:SetFont Pearl 8 -r
I usually set the font in the rastport instead of the screen. Then I
open and close a window (which has title bar in the new font). When the
window closes the my original CLI window also has its title bar in the new
font (poof!). However this opening and closing of windows is not
necessary to our experiment.
If I set the font only in the screen, with 'SetFont Pearl 8 -s',
Preferences *seems* to be OK, but I have not tested extensively.
5) Run Preferences. Change something (perhaps unnecessary, try some
variations). Save. No guru? Lucky you. Try again.
I think it sometimes works for a while but maybe I've got some variation
in the way I do things. By the way, as I think of it, I usually change
something on the Printer page since that's what I was trying to do when
Mr. Guru dropped by.
Subjectively, it seemed that the inclination of the system to crash got
worse as I tried to rerun Preferences after rebooting, modifying things
to try to track down the problem. There were times I couldn't even
Cancel my way out of Preferences without crashing. I recopied Preferences
and system-configuration from another disk, figuring they might be getting
trashed, but the failures continued. I disksalved the disk (twice).
I even powered off once. Same problems. I knew I had had the problem
before but couldn't remember what caused it. I had been through all this
before--argh. Finally I remembered, SetFont back to topaz 8 (This was
on a disk that had just been disksalv'ed and I'm not sure if the disksalv
was necessary.), and Preferences was well-behaved again. Note that I ran
SetFont twice and all was well (apparently). So if SetFont garbaged
things up, it ungarbaged them as well.
Finally this morning I tried the nominal copy of WB 1.2. The Guru I got
this morning was
81000009.265F48F1
which, if I read my 1.2 includes right, is the exec error 'freeing memory
already freed'.
By the way, after the Preferences window closed, but before Guru time,
I noticed this morning that my CLI window's title was back in Topaz.
So is this a problem with SetFont, Pearl, Preferences or what?

I'd given up playing with fonts, and was resigned to using Topaz, until I came across v2.0 of Andy's SetFont program. Seems like all the problems and crashes that I had had with SetFont v1.1 are gone (well, v2.0 doesn't crash *my* machine with "pearl" like v1.1 did, anyway). Since I've not seen it posted to the net, here is the uuencoded executable and documentation. Sorry, I don't have (or at least can't find) the sources. /kim # This is a shell archive.

I have, however, placed it in the PUBLIC DOMAIN. That, of course, means that you can do (almost) absolutely anything with it. You may hack it to bits, include it with YOUR product, sell it, GIVE IT AWAY, or anything else you like. Of course, since anyone else can also give it away, it would be foolish to stick your name on it and try to sell it. I really would like everyone to give it away, nicely, without being mean about it. If you want to use it with your product, do that too, new products for the Amiga are generally a good thing for the entire Amiga community. You can take bit and pieces and use them in your own programs, or the whole thing for that matter. And if you really want to have fun, you can even IMPROVE this program, as its far from perfect, and give YOUR version away too, if you're so inclined. That's about it for the (mundane) business section, let's get on to the (interesting) notes section. CHANGES FROM SetFont 1.0 SetFont 2.0's main improvement is that it allows the individual font of a CLI window to be changed without changing the font of the entire WorkBench Screen. The old SetFont would change the default font descriptor of the WorkBench screen, which is where most new programs get their fonts. This was useful in that a font so set would be inhereted by new WorkBench applications, like new CLIs, Word Processors, Terminal Programs, and just about anything run on the WorkBench Screen (as opposed to a custom screen). What the old version doesn't do is change JUST the font of the current CLI. The new version does this. I've thrown in the capability to also change the default title font of the screen (based on the screen's RastPort); this isn't incredibly useful, but it was very little extra code in addition to the two more useful functions. WHAT IT DOES This function changes the default fonts of the Amiga's WorkBench screen or an Amiga CLI window. This allows programs like CLI, etc. to use a font other than one specified by Preferences. This change isn't perfect, but it is useful. The program is used as: SetFont [fontname [points [place]] Where the "fontname" is a normal Amiga font, "points" is the font's point size, and place is currently one of: SCREEN The WorkBench Screen, ala SetFont 1.0 TITLES The WorkBench Screen's Titles WINDOW The current CLI window Setting the screen will essentially set the default font for newly created windows. Setting the title font will set the text displayed for window titles and things like that. This will look really ugly and generally not work very well if it is set to a font taller than the current screen font. Finally, setting the WINDOW font will set only the font of the calling CLI window. This will also clear the screen, which is required to fully set the font on an open console window. If no place is supplied, all three fonts are set. Examples are: SetFont (Displays current screen font) SetFont ? (Displays help text) SetFont topaz (Sets font "topaz 8" everywhere) SetFont ruby 12 (Sets font "ruby 12" everywhere) SetFont topaz 11 SCREEN (Sets font "topaz 11" on screen) SetFont thin 7 TITLES WINDOW (Sets font "thin 7" on CLI and titles) This program has a few limitations. First of all, some programs don't support fonts other than the 80 column, 8x8 cell "topaz 8" font, which is a default ROM font. If you're a 60 column user, you've probably experienced this before. Its not a problem with the Amiga as a whole, since most of the system will adjust itself. But it may be a problem with programs that have a fixed idea of what a font should look like. Most 80 column fonts work with most applications, and an 80 column 8x8 font will work just about everywhere. Some programs, like CLI for instance, have trouble with proportionally-spaced fonts. This is a "bug" or "feature" of the Amiga text display software, which is doing large amounts of spacing when only one character in a proportional font is displayed at a time. The best thing to do is try out the font you like. To use SetFont as a means of changing most of the default fonts during a session, insert it in your "s:Startup-Sequence" file, as: SetFont topaz 11 LoadWB EndCLI >nil: or something that (SetFont topaz 11 SCREEN TITLES would work just as well). One final problem is that some applications ask the WorkBench screen to close when they start up. It'll close if there's nothing else open on it, but when it re-opens, it'll restart with the Preferences-selected font, not the SetFont selected font. Of course, Preferences't support arbitrary fonts (which is why this program is even necessary). Oh well, maybe in 1.3? The simplest way to prevent this is to leave some kind of window open, which will prevent any other application from closing the WorkBench screen. Of course, if you need the memory that closing the WorkBench screen gives you, this would not be a good thing to do. //E*O*F setfont.doc// echo Possible errors detected by \'wc\' [hopefully none]: temp=/tmp/shar$$ trap "rm -f $temp; exit" 0 1 2 3 15 cat > $temp <<\!!! 154 1095 9374 setfont.uue 107 891 5510 setfont.doc 261 1986 14884 total !!! wc setfont.uue setfont.doc | sed 's=[^ ]*/==' | diff -b $temp - exit 0 -- UUCP: kim@amdahl.amdahl.com or: {sun,decwrl,hplabs,pyramid,ihnp4,seismo,oliveb,cbosgd}!amdahl!kim DDD: 408-746-8462 USPS: Amdahl Corp.

There's probably a disagreement between SetFont and Intuition (and Preferences) as to who has to Close the font and free the memory for the DiskFont structure. The only way to answer is to find out which SetFont you're using, and check it out. >Charles Cleveland EDU: chas@ss.physics.gatech.edu -- andy finkel {ihnp4|seismo|allegra}!cbmvax!andy Commodore/Amiga "An end is always a new beginning." - Captain Cloud Any expressed opinions are mine; but feel free to share.

I immediately implememted your version. However, the name in your docs is Dave Haynie (Andy F. is nowhere mentioned) whereas the SetFont 1.1 I had was from M. McInerny. Anyway, while the docs for Setfont 2.0 (Haynie) say One final problem is that some applications ask the WorkBench screen to close when they start up. It'll close if there's nothing else open on it, but when it re-opens, it'll restart with Preferences-selected font, not the SetFont selected font.... The simplest way to prevent this is to leave some ... window open, which will preven other application from closing the WorkBench screen.... in fact Preferences still wipes out all choices (WINDOW TITLES SCREEN) offered by SetFonts 2.0 (Haynie) except WINDOW as far as I can tell so far, even if an extra window is left open before Preferences is called. I can't believe Preferences tries to close WorkBench. But what the hell, 2.0 (Haynie) hasn't crashed my machine yet. -- Charles Cleveland EDU: chas@ss.physics.gatech.edu Georgia Tech School of Physics UUCP: ...!{akgua,allegra,amd,hplabs,ihnp4, Atlanta, GA 30332 masscomp,ut-ngp,rlgvax,sb1,uf-cgrl, unmvax,ut-sally}!gatech!gtss!chas

As atonement for my blunder, I will fire up YOMM (Ye Ol' MS-DOS Machine) this weekend, and do all my work on a single-tasking machine! Hope you agree that the punishment is in line with the crime. Dunno how that happened, 'specially since I looked thru the object code and most certainly saw *your* name in the embedded copyright notice. Well, at least I got the sex correct, and there *are* the same number of letters in both names ... :-) > I'll see if I can find the original sources and post 'em here when I do. That'd be nice. I came across your version on the BlitzFonts disk that Hayes ships out when one registers with him. He only distributed the executable and doc. Thanks alot for a real useful utility, Dave! /kim -- UUCP: kim@amdahl.amdahl.com or: {sun,decwrl,hplabs,pyramid,ihnp4,seismo,oliveb,cbosgd}!amdahl!kim DDD: 408-746-8462 USPS: Amdahl Corp.
