CacheFont v1.1
By Adam Dawes
25th September 1994
What Is CacheFont?
==================
CacheFont is a little utility that makes accessing your fonts significantly
quicker -- in fact, near instant.
I was always annoyed when using any programs on my Amiga which involved
fonts by the fact that when the program went to see what fonts were
available, I was presented with a rather lengthy wait. I decided I'd
finally had enough of this, and it was time to do something about it.
So after much poring over my keyboard and flicking through Amiga Intern, I
finally came up with a solution. This utility comes in two parts:
CacheFont . . . . Installs or removes CacheFont (run it once to install
the program, and a second time to remove it).
MakeFontList . . This program must be run before CacheFont can be used.
It creates the list of fonts that CacheFont will use
later in order to avoid reading the whole font list
again.
CacheFont relies entirely on the files made by the MakeFontList utility. If
your fonts directory is changed, CacheFont will *not* know anything about
it unless you run MakeFontList afterwards. Even rebooting your machine
won't change the list of fonts that CacheFont is aware of, so please run
the MakeFontList utility every time you change your font directory. It
takes only as long to run as a single font requester would've taken without
CacheFont, and I think you'll agree that your font directory is changed
much less often than you open a font requester!
System Requirements
===================
CacheFont will only work on an Amiga with OS2 or greater. You don't need a
harddrive, vast quantities of memory, or anything else.
Using CacheFont
===============
CacheFont is installed simply by entering its command from the command
line. It will print a message telling you that it has installed itself, and
from then on all your font requesters will be running through the patch.
If you wish to uninstall the patch, simply execute the command again and it
will remove itself.
The best way to install CacheFont is by including it in your
startup-sequence or user-startup. This way, the patch will be initialised
every time your system is booted.
You do not need to 'run' the program as it returns control to your command
line immediately.
Using MakeFontList
==================
MakeFontList must be run in order for the CacheFont to function. It scans
your Fonts: directory and stores the information needed by CacheFont in a
directory (which will be created if necessary) called Fonts:CacheFontData/.
If CacheFont has any difficulty reading these data files, it will display a
requester asking you to run MakeFontList, and continue by using the
original (slow) unpatched routine.
You will need to run MakeFontList every time you make a change to your
Fonts: directory. Don't include this command in your startup-sequence
though! Call it manually whenever you need to.
And how much disk space is wasted by the caching information files? Well I
have 55 fonts installed at the moment, and the cache files come out to a
whopping great 1581 bytes, hardly a great sacrifice. :)

Legal stuff
===========
Ok, so my associates and I have tested this program as extensively as we
can, and haven't found any bugs in it yet, but sod's law clearly dictates
that the experiences of the many are worse than the experiences of the few.
I won't accept responsibility for any damage done to your system or data
lost, directly or indirectly, as a result from using CacheFont or any of
its associated files. You use the program entirely at your own risk. Of
course if you *do* experience problems then I'll do what I can to sort them
out, and please let me know so that I can try to cure them in a future
version of CacheFont.
CacheFont and its associated files are not public domain. They may be
distributed freely as long as no unreasonable charge is imposed. It may not
be included within any commercial package without express written
permission from the author; the exceptions from this are the AmiNet CDs and
Fred Fish's utility collections. CacheFont and its associated utilities may
only be distributed if all files contained within the original archive are
present.
History
=======
Version 1.0 (1/9/94)
o Initial release.
o Thanks to the following people for assistance in testing:
Nick Doyle
Jon Hudson
Lars Janssen
Roger Kille
Mark Stacey
Tim Still
Nicholas Wynne
Version 1.1 (25/9/94)
o CacheFont now understands Tagged font lists. This should keep it
working with most (if not *all*) of the programs that crashed version
1.0 (eg, FontPrefs by Martin Stengle). Note that CacheFont doesn't
actually return the tags at the moment, it always returns a null
pointer. Whilst this isn't entirely useful, it does stop crashes. My
thanks to Bret McGee for helping my find and solve this bug (aswell
as for some other very nice ideas which have yet to be implememted).
o Version strings are now Commodore Style-Guide compliant (thanks to
everyone who pointed that one out to me! :)
