Cody Boone Ferguson 8541a49291 Add missing file in 2001/rosten
The new file, greasymouse.man, IS the cat man page noted by the author
in their remarks. This file was provided by Leo as remark.txt but to
make it render better I have made it a .man file and, for syntax
highlighting, I moved the section titles to the first column of the
file.

I thought of making it a true man page but as the author suggested that
it is a cat man page I decided against this.

NAME
greasymouse - make the mouse act as if it has been greased
SYNOPSIS
greasymouse [greasiness]
DESCRIPTION
This program is designed primarily to make your X windows interface more
obfuscated. Try doing something mouse driven (such as using a mouse
driven editor on this program) whilst it is running. If you're not sure
what it does, looking at the code should give a fair idea.
OPTIONS
It only takes one optional option: the greasiness factor. This is the
number that the speed is divided by on each iteration. The default is
1.03. A setting of 1 (no friction is fun), as is 0.99.
Being an X program, it recognised the DISPLAY variable.
PORTABILITY
The program is very portable, even to non X architectures. All that is
required is a large desk and some good grease.
COMMENTS
It is really rather surprising that code like this should not only be
portable, but compile with almost no warnings on most of the compilers
tested. It's a kind of shame that none of the compilers do anything like
this:
$make greasymouse
cc greasymouse.c -o greasymouse -lX11
greasymouse.c:30: This macro should have more text and spaces in it
greasymouse.c:32: This is a really stupid way to perform this operation
greasymouse.c:42: This program would look better with a newline here
greasymouse.c:48: That's a really silly thing to do
greasymouse.c:55: So is that
...
greasymouse.c:58: This program is rubbish. I'm not going to link it.
$
The code is best viewed with tabstops every 8 spaces.
BUGS
The mouse gets stuck completely if you give it an option of less than 1
and leave it for too long. This is quite annoying if it didn't leave the
terminal if was run from in focus.
It gets very jerky if the processor is being used. There are better time
functions than clock() but I haven't used them.
It deflects slightly when it gets very slow.
It annoys other people if you run it on their display too often. Maybe I
should make future versions print funny jokes to keep the humor fresh.
It's pretty ropey over a 56K modem.
It's even ropier over a 56K modem and tunneled through 3 ssh links.
WARNINGS
Pages and pages and pages of things, with GCC at any rate.
It suggests loads of ()'s where they're not needed.
It reckons I have not used some of the values I have computed. I would
never do a thing like that: I just haven't used them in the way it's
used to.
The MIPS compiler suggests an == instead of an = in expressions such as
&&(a=b)
but I its suggestions would break my program.
It also reckons that r() has no prototype.
Giving the -pedantic option to the MIPS compiler causes it to generate
warnings about its own header files, but not any extra ones with this
program.
With all warnings enabled, the DEC compiler, oddly enough finds some
problems with its own include files, but none with my program.
ERRORS
The DEC compiler of this version:
DEC C V5.6-079 on Digital UNIX V4.0 (Rev. 878)
can't compile the code. It thinks that preprocessor lines can not have
whitespace preceding the #. Moving the preprocessor directives to the
beginning of the line wrecks the layout but makes it compile.
