# Most compiles will safely use -O2. Some can use only -O.
|
||||
# A few compilers have broken optimizers and thus you may
|
||||
# not want anything.
|
||||
# Regarding individual entries:
|
||||
#
|
||||
# IOCCC winning entry code may not work on your system. Even with standards,
|
||||
# conditions and build environments change, especially when it comes to more
|
||||
# extreme code such you might find in an IOCCC winner. Moreover, what was
|
||||
# allowed and liked in one IOCCC contest may no longer be liked/allowed in
|
||||
# later IOCCC years.
|
||||
#
|
||||
# Corrections on winning author and fixing typos in remarks are VERY WELCOME.
|
||||
#
|
||||
# GitHub pull requests are welcome:
|
||||
#
|
||||
# If you have a patch that might make running an entry work in modern Unix-like
|
||||
# environments, please create a GitHub pull request for the IOCCC judges to
|
||||
# consider.
|
||||
#
|
||||
# Suggestions and corrections regarding Makefiles, winning author information,
|
||||
# fixing typos in remarks, and code patches are welcome via opening a GitHub
|
||||
# issue or better yet, by creating a GitHub pull request for the IOCCC judges
|
||||
# to consider. To form a GitHub issue or GitHub pull, please visit:

|

This small program might be a nice addition to a digital personal
|
||||
organizer; just in case you are stranded on a desert island and need to
|
||||
signal your distress to passing ships.
|
||||
|
||||
The obfuscation in this program is truly masterful. The program is
|
||||
very cleverly obscured without the use of a single #define!
|
||||
Reformatting this program by hand :-) is the easiest way to understand
|
||||
what is going on.

This program is a simple filter that translates ASCII text into
|
||||
semaphore code. It reads from standard input and converts all
|
||||
alphanumeric characters to their corresponding semaphore codes.
|
||||
Consecutive whitespace is translated as a single 'break' code. Newlines
|
||||
also cause the next code to be output on a new line. All other
|
||||
characters are ignored. The codes themselves are written to standard
|
||||
output as a depiction of a person holding two flags, using only ASCII
|
||||
characters (semaphore smileys, if you will). For example, given the
|
||||
input "Hello, world!", the output will be:
|
||||
|
||||
<> <> <> <> <> <>
|
||||
_() ()/ ()/ ()/ _\) () (/_ _\)

To build:
|
||||
The program is obfuscated without the use of the preprocessor or any
|
||||
special compilation parameters. In fact, the program doesn't even
|
||||
bother using any keywords, save the single 'char' at the beginning.
|
||||
This program was crafted using only operator precedence rules,
|
||||
short-circuit evaluation and recursion. Each function contains a
|
||||
single, non-empty statement. (I did have to add a couple of empty
|
||||
statements to format the code properly.) There is a single string
|
||||
constant which encodes the flag positions and other data needed for
|
||||
drawing the semaphore codes.
|
||||
|
||||
make anderson
|
||||
The preprocessor will provide no help in un-obfuscating this code, and a
|
||||
C beautifier won't get you very far either. You just have to crunch
|
||||
through it.
|
||||
|
||||
To run:
|
||||
An ANSI C compiler will generate several warnings when it compiles this
|
||||
program, as none of the functions declare their return type, nor do they
|
||||
return anything. This was necessary to keep the program free of
|
||||
keywords. It's valid in K&R C, and compiles in ANSI C. There are also
|
||||
warnings about conversion from 'int' to 'char' and the resulting loss of
|
||||
data. Again, if it's OK with K&R, it's OK with me.

This program is a great teaching tool for learning the semaphore code;
|

and if you don't have any flags handy you can just use two copies of the
|
||||
source file.
