build index.html for all winners
Updated manifest as per recent file changes. Updated winner `.winner.json` to reflect the manifest changes. Added [bin/all_run.sh](bin/all_run.sh) tool to run a command over all winning entries. These tools had slight improvements in the help usage message: * bin/gen-author.sh VERSION="1.3.1 2024-01-16" * bin/gen-inventory.sh VERSION="1.0.1 2024-01-16" * bin/pandoc_wrapper.sh VERSION="1.3.1 2024-01-16" * bin/subst.default.sh VERSION="1.1.1 2024-01-16" * bin/subst.winner-index.sh VERSION="1.1.1 2024-01-16" The `bin/readme2index.sh` tool was improved so that if the `index.html` file exists and the tool forms the exact same content, then the file `index.html` file is NOT touched. * bin/readme2index.sh VERSION="1.1 2024-01-16" We used the following command to generate `index.html` files for all winning entries: ```sh bin/all_run.sh -v 3 bin/readme2index.sh ``` NOTE: We have not (yet) built HTML files above the winner directory level (e.g., no year level nor top level HTML), nor have be built non-index HTML files for winners. NOTE: By default we are running `pandoc(1)` with: ``` --fail-if-warnings=true ``` This means that any problems with markdown to HTML generates an error. This is done to be sure that the HTML conversion is clean. We had to fix the following `README.md` files: * `2000/rince/README.md` The reference [^2] was never used. We made a guess that [^2] applies to the same spot as [^1]. Perhaps there is a better spot where [^2] applies? NOTE: For every reference, there MUST be some place where that reference is used. * 2012/vik/README.md The string "$...$" is assumed to be a TeX encoded string. NOTE: Every "$..$" needs to be backslashed as in "\$..\$". * 2018/burton1/README.md The reference [2] was duplicated. We changed the second [2] to [3]. NOTE: Every reference needs to have a unique number. * 2020/carlini/README.md The string "$...$" is assumed to be a TeX encoded string. NOTE: Every "$..$" needs to be backslashed as in "\$..\$". We also found 2 errors in the `author/author_handle.json` file set: * author/Anonymous_2001.json The `author/Anonymous_2001.json` file was missing. * author/Jari_Arkko.json The winner ID for `1989_jar.1` had a typo.

|

you’re using Turbo-C or MSC, the code is available, based on the
|
||||
authors’ remarks except that the <code>" #Q"</code> string was not
|
||||
changed as that showed worse looking output instead of improved output
|
||||
though admittedly we have no way to test the compilers in question.
|
||||
YMMV.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>This program reads an integer between 4 and 99 from the
|
||||
<code>stdin</code>.</p>
|
||||
<p>NOTE: The original program did not have a newline at the end of the
|
||||
file. We added a final newline to the file to make unpacking easy.</p>
|
||||
<h2 id="authors-remarks">Authors’ remarks:</h2>
|
||||
<p>The goal of this work was to write a program that solves the classic
|
||||
<a href="https://en.wikipedia.org/wiki/Eight_queens_puzzle">n-queens
|
||||
problem</a>, with a board size of up to 99x99, while keeping the program
|
||||
as short as possible.</p>
|
||||
<p>The program finds all possibilities to place N chess queens on an NxN
|
||||
<a href="https://en.wikipedia.org/wiki/Chessboard">chessboard</a> so
|
||||
that no queen is in range of any other queen (not in the same column row
|
||||
or diagonal). For each solution the chess board and the place of the
|
||||
queens is printed to stdout.</p>
|
||||
<p>This program is about as simple and as readable as possible. To make
|
||||
things even more simple we used a very limited subset of C:</p>
|
||||
<ul>
|
||||
<li>No pre-processor statements</li>
|
||||
<li>Only one, harmless, <code>for</code> statement</li>
|
||||
<li>No <code>if</code>s</li>
|
||||
<li>No <code>break</code>s</li>
|
||||
<li>No <code>case</code>s</li>
|
||||
<li>No functions outside the standard C library</li>
|
||||
<li>No <code>goto</code>s</li>
|
||||
<li>No structures</li>
|
||||
</ul>
|
||||
<p>In short, it contains no C language that might confuse the innocent
|
||||
reader. :-)</p>
|
||||
<p>This program demonstrates the claim that in C, any program can be
|
||||
written using a single ‘for’ statement, as long as it is long
|
||||
enough.</p>
|
||||
<h3 id="for-pc-users">For PC users:</h3>
|
||||
<p>In order to compile the program under Turbo-C or MSC,
|
||||
<code>int</code> should be inserted at the beginning of the program. For
|
||||
better looking results it is recommended to replace the
|
||||
<code>" #Q"</code> string with <code>" \261\2"</code>.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>The Makefile uses several <code>-D</code> defines. The following is
|
||||
is a list of the macros that may be changed:</p>
|
||||
<ul>
|
||||
<li><code>-DM=<max bet allowed></code></li>
|
||||
<li><code>-DN=<52 * number of decks used></code></li>
|
||||
<li><code>-DX=<how to seed the rand() generator></code></li>
|
||||
</ul>
|
||||
<p>The macro <code>V</code> should remain <code>void</code>.</p>
|
||||
<p>The author noted that a compiler being used assumed that
|
||||
<code>x=*p++</code> means <code>x*=p++</code> but do you know why? This
|
||||
is not so strange as it might seem if you look at <a
|
||||
href="https://www.bell-labs.com/usr/dmr/www/chist.html">C’s history</a>.
|
||||
Example code where this occurs is in John Lions’ Commentary on the Sixth
|
||||
Edition UNIX Operating System.</p>
|
||||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||||
<p>This is a blackjack program. It does splits, doubling down,
|
||||
insurance, etc.</p>
|
||||
<p>As best I can figure, it should be ANSI-compliant, as well as
|
||||
portable to BSD & SysV (as well as the irritating compiler I was
|
||||
using which assumes <code>x=*p++</code> means <code>x*=p++</code>!). It
|
||||
is reasonably robust in its error handling—it won’t let you split,
|
||||
double, etc. unless you actually have the cash, etc. To terminate the
|
||||
program, hit <code>EOF</code> or type <code>0</code> or a negative
|
||||
number for you wager.</p>
|
||||
<p>The way it deals with splits is particularly cool (IMHO). You can
|
||||
split many times, and it will show all hands as they are played.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>Some C preprocessors got confused about single quotes in certain
|
||||
cases. In particular, the following source line:</p>
|
||||
<div class="sourceCode" id="cb4"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb4-1"><a href="#cb4-1" aria-hidden="true" tabindex="-1"></a>b12<span class="op">(</span>ase<span class="op">(</span>bco<span class="op">(</span>acp<span class="op">(</span>bi<span class="op">(</span>acp<span class="op">(</span>bcp<span class="op">(</span>acp<span class="op">(</span>bpl<span class="op">(</span>aqu<span class="op">(</span>bqu<span class="op">(</span>A<span class="op">))))))))))))))))))))))))))))))</span></span></code></pre></div>
|
||||
<p>sometimes has to be changed to:</p>
|
||||
<div class="sourceCode" id="cb5"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb5-1"><a href="#cb5-1" aria-hidden="true" tabindex="-1"></a>b12<span class="op">(</span>ase<span class="op">(</span>bco<span class="op">(</span>acp<span class="op">(</span>bi<span class="op">(</span>acp<span class="op">(</span>bcp<span class="op">(</span>acp<span class="op">(</span>bpl<span class="op">(</span><span class="ch">'A'</span><span class="op">))))))))))))))))))))))))))))</span></span></code></pre></div>
|
||||
<p>particularly if the C preprocessor botches single quotes in cpp
|
||||
expansions, which we have done for the wider audience.</p>
|
||||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||||
<p>If my preprocessor could hack it, I could write this as one single
|
||||
line rather than 4, but when I do that I get a complaint “defines nested
|
||||
too deeply”.</p>
|
||||
<h3 id="obfuscation-spoiler">Obfuscation spoiler:</h3>
|
||||
<p>This is another rot13 job (believe it or not) - the
|
||||
<code>#defines</code> are a novel way of adding tokens:
|
||||
<code>#define b12(x) 12 x</code> means that at some point in the source
|
||||
a <code>12</code> is followed by the compressed nested
|
||||
<code>#define</code>s. The <code>b12</code> gets the previous
|
||||
compression as an argument, and prepends the <code>12</code>, thus
|
||||
making another step in the recreation of the source. The
|
||||
<code>axx()</code> <code>#define</code>s do the same, but add tokens
|
||||
after.</p>
|
||||
<p>As for the rot13 algorithm, it relies on <code>index(3)</code> to
|
||||
find if the character is in the set <code>A-Za-z</code>.
|
||||
<code>l[]</code> is an array that gets filled with:</p>
|
||||
<div class="sourceCode" id="cb6"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb6-1"><a href="#cb6-1" aria-hidden="true" tabindex="-1"></a><span class="st">"nopqrstuvwxyzzzzabcdefghijklmmmmNOPQRSTUVWXYZZZZABCDEFGHIJKLMMMM"</span></span></code></pre></div>
|
||||
<p>If <code>index(3)</code> says the char is in the alphabet, then XOR
|
||||
the offset with <code>16</code> to translate, and output, otherwise pass
|
||||
it unchanged.</p>

<p>The program, in its base form, implements two useful utilities:</p>
|

<ul>
|

<li><code>atob</code> - ASCII to binary conversion</li>
|

<li><code>zcat</code> - decompression filter</li>
|

</ul>
|

<p>Included with this entry is a shell script (with comments edited down

to reduce it to 1530 bytes) which implements the complete shark utility.
|

The script, <a href="shark.sh">shark.sh</a>, contains a

<code>jaw.c</code> embedded within it!</p>
|

<p>The sender must have <code>compress</code> and <code>btoa</code>. To

|

<p>The resulting file, <code>receive</code>, unpacks the input files

even if the receiver lacks <code>uncompress</code> and

<code>btoa</code>:</p>

|

<hr />
|
||||
<p>Myriad formats have been proposed for network-mailable data. A major
|
||||
difficulty undermining the popularity of most file/message bundlers is
|
||||
that the sender assumes prior installation of the computational dual of
|
||||
such bundling software by the receiver. Command shell archives alleviate
|
||||
this problem somewhat, but still require standardization for the
|
||||
function of data compression and mail-transparency encoding. On Unix,
|
||||
these coding format quandaries are overcome by planting a novel <a
|
||||
href="https://en.wikipedia.org/wiki/Trojan_horse_(computing)">Trojan
|
||||
Horse</a> in the archive header to perform negotiation-less
|
||||
decoding.</p>
|
||||
<p>Specifically, we outline the development of an extraordinarily
|
||||
compact portable bundler/extractor to (dis)assemble data-compressed,
|
||||
binary-to-ASCII-converted, length-split, and checksummed directory
|
||||
structures using standard Unix tools. Miniature versions of counterparts
|
||||
to a Lempel-Ziv coder (<code>compress</code> or <code>squeeze</code>)
|
||||
and an efficient bit packetizer (<code>btoa</code>) are compiled
|
||||
on-the-fly at mail destination sites where they may not already exist.
|
||||
These are written in purposefully obfuscated-C to accompany
|
||||
similarly-shrunk shell command glue. This resulting shell archiver is
|
||||
dubbed <code>shark</code>.</p>
|
||||
<p><code>shark</code> procedure overhead consumes as few as three dozen
|
||||
shell commands (or <code>~1100</code> bytes), commensurate with the size
|
||||
of many Internet mail headers; it amortizes favorably with message size.
|
||||
<code>shark</code> is portable across Unix variants, while the
|
||||
underlying technique is inherently generalizable to other encoding
|
||||
schemes.</p>
|
||||
<p>In the function-theoretic sense of minimal Chaitin/Kolmogorov
|
||||
complexity, and within a modified Shannon model of communication, the
|
||||
‘shark’ effort aims to construct a “shortest program” for source
|
||||
decoding in the Turing-universal Unix environment.</p>
|
||||

|

<p>Oh, the shark has pretty teeth, dear–<br />

<p>We have ported this program to a wide variety of systems. Among these

are:</p>
|

<ul>
|

<li>SunOS 4.1 / Sun SPARCstation 1 (using both ‘cc’ and ‘gcc

<h3 id="obfuscation">Obfuscation</h3>
|
||||
<p>We (the authors) feel this program is obfuscated for the following
|
||||
reasons:</p>
|
||||
<ol start="0" type="1">
|
||||
<li><p>This is one of the few programs you’ll see <em>WHOSE VERY UTILITY
|
||||
DEPENDS ON ITS OBFUSCATION</em>!</p></li>
|
||||
<li><p>The contest entry may be used to send its wonderful self to
|
||||
anyone in the Unix world! Virus writers need not apply…</p></li>
|
||||
<li><p>The basic idea is twisted enough to be patentable, but is, out of
|
||||
the kindness of our hearts (as well as to maintain eligibility for the
|
||||
large IOCCC prize fund), dedicated to the public domain. Claude Shannon,
|
||||
meet Alan Turing.</p></li>
|
||||
<li><p>Meta-obfuscation is via obfuscated description (see
|
||||
<em>ABSTRACT</em>).</p></li>
|
||||
<li><p>“Literary” allusion. Production code contains a reference to
|
||||
self-reference, preserved at amazing cost for sheer perversity.</p></li>
|
||||
<li><p>Many, many micro obfuscations below, honed over three years time,
|
||||
in shell as well as C. Ask about the ‘tar’ pit escape, the
|
||||
<code>argv[0]</code> flip, Paul’s <code>&4294967295</code>
|
||||
portability hack, the “void where prohibited by flaw” fix, the
|
||||
<code>scanf()</code> space-saver, shift shenanigans, signal madness,
|
||||
<code>exit()</code>ing stage left, and source-to-source transformations
|
||||
galore.</p></li>

<h3 id="shark-history">Shark history:</h3>
|
||||
<ul>
|
||||
<li><p>May 1987: Karl Fox introduces 1023-byte <code>zcat.c</code> to
|
||||
USENET. It’s too late for the 4th IOCCC.</p></li>
|
||||
<li><p>May 21, 1987: James A. Woods extends idea to construct self
|
||||
decompressing <code>shar</code> Trojan horse, utilizing <code>cc</code>,
|
||||
<code>shar</code>, <code>zcat</code>, & <code>btoa</code>; size:
|
||||
2303 bytes.</p></li>
|
||||
<li><p>May 23, 1987: <code>jaw</code> trims 250 bytes without much
|
||||
thought.</p></li>
|
||||
<li><p>June 2, 1987: 52 lines of shell, 1991 bytes, now made with
|
||||
<code>tar</code>, short-circuit C-compile at far end, dual-use main.c,
|
||||
portability mods. (jaw)</p></li>
|
||||
<li><p>Mar-May 1988: abortive run at 5th IOCCC. <code>jaw.c</code> -
|
||||
1529 bytes. compile line: 152 bytes. generated funny code with
|
||||
<code>execvp()</code> to invoke shell.</p></li>
|
||||
<li><p>Aug 29, 1988: production version, now at 1830 bytes.</p></li>
|
||||
<li><p>Jan 1990: Paul Eggert does tour-de-force shark
|
||||
re-engineering.</p></li>
|
||||
<li><p>May 24, 1990: collaboration yields 999-byte <code>jaw.c</code>
|
||||
core (see above) and 1530-byte production shell code (w/comments).
|
||||
Eggert comes through with lion’s share of improvements. 7th IOCCC code
|
||||
now faster than the <code>btoa</code>/<code>zcat</code> it
|
||||
replaces.</p></li>
|
||||
<li><p>May 1990: <code>jaw</code> develops experimental replacement
|
||||
using Dan Bernstein’s high-compression ‘squeeze’.</p></li>
|
||||
</ul>
|
||||
<p>To which we add:</p>
|
||||
<ul>
|
||||
<li>June 1990: <code>shark</code> wins the IOCCC, finally! :-)</li>

||||

|

<p>This program prints out a string. Can you figure out how it is
|
||||
done?</p>
|
||||
<p>By use of pointers to functions returning a struct of pointers to
|
||||
functions!</p>
|
||||
<h3 id="spoiler">Spoiler:</h3>
|
||||
<p>This program prints out the string:</p>
|
||||
<blockquote>
|
||||
<p>the quick brown fox jumped over the lazy dog</p>
|
||||
</blockquote>
|
||||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||||
<p>It is simple to make the program print other strings. Each
|
||||
alphabetical character from a to z is printed out as its opposite:</p>
|
||||
<pre><code>a->z b->y c->x etc</code></pre>
|
||||
<p>To encode a new string input the string as it is meant to come
|
||||
out:</p>
|
||||
<div class="sourceCode" id="cb7"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a>X<span class="op">=</span>s<span class="op">().</span>v<span class="op">().</span>o<span class="op">().</span>o<span class="op">().</span>l<span class="op">().</span>S<span class="op">().</span>d<span class="op">().</span>l<span class="op">().</span>i<span class="op">().</span>o<span class="op">().</span>w<span class="op">().</span>N<span class="op">();</span></span></code></pre></div>
|
||||
<p>Note: <code>S()</code> represents a space and <code>N()</code> a
|
||||
newline. This will now produce…</p>
|
||||
<pre><code>hello world</code></pre>
|
||||
<p>By the way, there is actually a piece of code which is not used in
|
||||
the original program! I leave it as an intellectual exercise to the
|
||||
reader to find out what it is.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>The addition of trigraphs has made it easier to make programs hard to
|
||||
read. It was a dark and stormy night for C when the ANSI C committee
|
||||
added trigraphs to the standard. Too bad that they didn’t just simply
|
||||
require a more reasonable ISO character set.</p>
|
||||
<p>The Author sent us this note after he was informed that he won:</p>
|
||||
<blockquote>
|
||||
<p>Although I am quite grateful for the “ANSI Committee’s Worst Abuse of
|
||||
C” title (were you aware that I am a member of the committee or is the
|
||||
double meaning unintentional?), I was really hoping for something more
|
||||
along the lines of “Closest Resemblance to Line Noise.” :-)</p>
|
||||
</blockquote>
|
||||
<p>… it was unintentional.</p>
|
||||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||||
<p>Since this year’s contest is dedicated to ANSI C, here is a strictly
|
||||
conforming entry. In accordance with the ANSI definition of a strictly
|
||||
conforming program it does not produce output dependent on any
|
||||
unspecified, undefined, or implementation defined behavior, and it does
|
||||
not exceed any of the minimum implementation limits. It adheres to all
|
||||
of the syntactic and semantic constraints of the standard: it
|
||||
<code>#include</code>s the relevant headers for the functions it uses,
|
||||
and it uses the <code>EXIT_SUCCESS</code> and <code>EXIT_FAILURE</code>
|
||||
macros to return a correct success/fail status to the invoking program.
|
||||
It also uses trigraphs for characters which are not in the
|
||||
<code>Invariant Code Set</code> of <code>ISO 646:1983</code>, so it will
|
||||
be portable to machines with deficient (from C’s standpoint) character
|
||||
sets. In short, it should be very widely portable. As an extra added
|
||||
attraction, all of the lines are under 72 characters long, which would
|
||||
allow for sequence numbers to be punched in columns 73-80 :-).</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>We changed the alias that the author’s suggested alias from a C-shell
|
||||
alias to a Bourne-like shell alias.</p>
|
||||
<p>Note that <code>shst.c</code> is renamed to <a
|
||||
href="stig.c">stig.c</a> in the distribution.</p>
|
||||
<p>WARNING: This program’s <code>how to compile</code> is too specific
|
||||
to a particular shell. The obfuscation of this program is more related
|
||||
to shell obfuscation than C obfuscation. This type of entry will not be
|
||||
permitted in future contests.</p>
|
||||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||||
<p>If you like shell programming you may also admire my creative
|
||||
quoting. (I use <code>echo</code> to create an alias which when run
|
||||
calls cc with the <code>-D</code> option to create a C macro with double
|
||||
quotes in it. ARRRRRGGGHHH!)</p>
|
||||
<p>The program is totally portable, but the compile commands are very
|
||||
shell specific so don’t be TOO mad at me if they don’t work for you.</p>
|
||||
<p>If you want to put these commands in a Makefile you must add 4 - four
|
||||
- backslashes at the end on first line. (At least that’s what works
|
||||
here.)</p>
|
||||
<p>If everything works correctly it create an executable named
|
||||
<code>o</code> which checks whether your compiler supports nested
|
||||
comments. I’ve stolen the <code>"/*/*/0*/**/1"</code> from somewhere so
|
||||
don’t give me any points for it. Of course neither ANSI nor K&R
|
||||
support nested comments when properly implemented, but what the
|
||||
heck.</p>

<h3 id="a-note-about-the-fixes-of-this-entry-in-2023">A note about the
|
||||
fixes of this entry in 2023:</h3>
|
||||
<p>In 2023 it was noticed that in some systems like macOS there was
|
||||
confusing output due to a warning at runtime that was interspersed with
|
||||
the output of the program. For instance it would show:</p>
|
||||
<div class="sourceCode" id="cb3"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb3-1"><a href="#cb3-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./tbr</span></span>
|
||||
<span id="cb3-2"><a href="#cb3-2" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> warning: this program uses gets<span class="er">(</span><span class="kw">)</span><span class="ex">,</span> which is unsafe.</span></code></pre></div>
|
||||
<p>which kind of hid the prompt. Thus the entry was changed to use
|
||||
<code>fgets(3)</code> which is referred to later in this file.</p>
|
||||
<p>Also <code>exit(3)</code> returns <code>void</code> but the entry was
|
||||
using it in a binary expression so this entry would not compile in
|
||||
modern systems. This fix is also referred to below, in the <a
|
||||
href="#alternate-code">alternate version</a> section.</p>
|
||||
<h2 id="to-use">To use:</h2>

||||

|
||||
<span id="cb4-2"><a href="#cb4-2" aria-hidden="true" tabindex="-1"></a><span class="ex">$</span> enter some shell commands</span></code></pre></div>
|
||||
<p>NOTE: globs do not work with this entry. Why?</p>
|
||||
<p>NOTE: <code>exit</code> does not work and neither does
|
||||
<code>logout</code>. To exit try sending ctrl-d or ctrl-c (or kill it
|
||||
from another terminal :-) ). But why does it not work with just
|
||||
<code>exit</code> or <code>logout</code>? Hint: see the authors’
|

remarks.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>This program touches on a well known Unix utility, the 6th edition
|
||||
Bourne Shell (<code>/bin/sh</code>), whose original source was
|
||||
considered to be extremely obfuscated by many people (although Steve
|
||||
Bourne might disagree). Did you know that the Bourne Shell source was a
|
||||
major inspiration for the formation of the IOCCC back in 1984?</p>
|
||||
<h2 id="authors-remarks">Authors’ remarks:</h2>
|
||||
<p>This program is a rudimentary shell. It does I/O redirection, pipes
|
||||
and cd. It flags errors on failed <code>chdir()</code>,
|
||||
<code>open()</code>, <code>creat()</code>, <code>execvp()</code>,
|
||||
<code>fork()</code> and a few syntax errors.</p>
|
||||
<p>This program is obfuscated in a few notable ways: apart from the
|
||||
layout (an unformatted (but crunched) version is included for people who
|
||||
want to put this through <code>cb</code>) it makes clever use of a
|
||||
<code>write()</code> statement, so that the same statement can be used
|
||||
to print errors and the prompt. By calling the error function with the
|
||||
value <code>-8</code>, the pointer offset in the expression
|
||||
<code>"?\n$ "-x/4</code> goes from 0 to 2. Presto! A prompt. For errors
|
||||
with numbers smaller than <code>-4</code> (i.e., UNIX system calls) a
|
||||
question mark is printed.</p>
|
||||
<p>The error value of <code>chdir()</code> is doubled so that we don’t
|
||||
exit from the parent shell on a <code>chdir()</code> error (since
|
||||
<code>e()</code> exits on <code>-1</code> errors only). All other system
|
||||
call failures exit since they are from sub-shells.</p>
|
||||
<p>Recursion is sneakily employed to avoid a second call to
|
||||
<code>fork()</code>, and the line is parsed in a fairly bizarre fashion:
|
||||
backwards. The heart of the program, that is, the part which performs
|
||||
all <code>fork()</code>s, <code>exec()</code>s, <code>open()</code>s,
|
||||
etc. is ONE C STATEMENT.</p>
|
||||
<p>The meta-values array is initialized in a bizarre fashion, and the
|
||||
subsequent checks for the <code>'<'</code> and <code>'>'</code>
|
||||
are performed in a single statement using a mask, since you know that
|
||||
<code>'>'&2</code> is 0, whereas <code>'<'&2</code> is 2.
|
||||
Other such micro-obfuscations abound.</p>
|
||||
<p>Finally, it is notable that the code was hacked for minimality. If
|
||||
you look at the compressed version, you will be hard-pressed to
|
||||
eliminate more than a few characters (we can’t see how to make it any
|
||||
smaller!). 550 characters is pretty lean for a shell that does this
|
||||
much.</p>
|
||||
<h3 id="bugs">BUGS</h3>
|
||||
<p>The syntax of the shell has not been fully explored, but if you try
|
||||
to redirect in the same direction more than once, only one redirection
|
||||
is performed. This is a “feature” of the way the line is parsed; a
|
||||
pointer to the stack of arguments is assigned and an argument is stolen
|
||||
every time a <code>></code> or <code><</code> is encountered. The
|
||||
shell flags an error if no arguments are on the stack. Thus, for
|
||||
example:</p>
|
||||
<div class="sourceCode" id="cb9"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb9-1"><a href="#cb9-1" aria-hidden="true" tabindex="-1"></a><span class="fu">cat</span> <span class="op">></span> foo <span class="op">></span> bar</span></code></pre></div>
|
||||
<p>cats to <code>foo</code>, since it was pushed last, but</p>
|
||||
<div class="sourceCode" id="cb10"><pre
|
||||
class="sourceCode sh"><code class="sourceCode bash"><span id="cb10-1"><a href="#cb10-1" aria-hidden="true" tabindex="-1"></a><span class="fu">cat</span> <span class="op">></span> <span class="op">></span> foo bar</span></code></pre></div>
|
||||
<p>cats to <code>bar</code>, since <code>bar</code> was pushed under
|
||||
<code>foo</code> (remember we’re parsing right-left).</p>
|
||||
<p>Depending on your flavor of Unix, <code>cd</code> without an argument
|
||||
will either produce an error or just do nothing.</p>
|
||||
<p>There is just one error message, the question mark, but hey, that’s
|
||||
all <code>ed(1)</code> does too.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>The program’s source implements four functions, all from the same
|
||||
source file!</p>
|
||||
<p>When you compile <a href="theorem.c">theorem.c</a> as is and run with
|
||||
5 args, it numerically solves the equation <code>y'=f(x,y)</code>, with
|
||||
a step size of <code>h</code> (see above usage), over the interval
|
||||
<code>x=[x1,x2]</code>, with the initial condition of
|
||||
<code>y(x1)=y1</code>.</p>
|
||||
<p>The ‘expression’ <code>f(x,y)</code> is any function of
|
||||
<code>x</code> and <code>y</code> with the operators:</p>
|
||||
<pre><code>+ - * / ^</code></pre>
|
||||
<p>The symbol <code>^</code> is the power operator. Note that it only
|
||||
supports integer powers. Also note that all expressions are evaluated
|
||||
strictly left to right. (i.e., parenthesis aren’t supported).</p>
|
||||
<p>Try running the program with the following args:</p>
|
||||
<div class="sourceCode" id="cb7"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./theorem</span> y 0 1 0.1 1</span>
|
||||
<span id="cb7-2"><a href="#cb7-2" aria-hidden="true" tabindex="-1"></a><span class="ex">./theorem</span> 1/x 1 2 0.1 0</span>
|
||||
<span id="cb7-3"><a href="#cb7-3" aria-hidden="true" tabindex="-1"></a><span class="ex">./theorem</span> <span class="st">'x^2/y+x'</span> 0 1 0.1 6</span></code></pre></div>
|
||||
<p>But wait, there is more! You also get, free of charge, a reversing
|
||||
filter! Try:</p>
|
||||
<div class="sourceCode" id="cb8"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb8-1"><a href="#cb8-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./theorem</span> <span class="at">-r</span> 0 0 0 0 <span class="op"><</span> theorem.c <span class="op">></span> sorter.c</span></code></pre></div>
|
||||
<p>Still not impressed? The author throws in for free, a sort program!
|
||||
Try:</p>
|
||||
<div class="sourceCode" id="cb9"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb9-1"><a href="#cb9-1" aria-hidden="true" tabindex="-1"></a><span class="fu">make</span> sorter</span>
|
||||
<span id="cb9-2"><a href="#cb9-2" aria-hidden="true" tabindex="-1"></a><span class="fu">ls</span> <span class="kw">|</span> <span class="ex">./sorter</span></span></code></pre></div>
|
||||
<p>This program is safe for home use as well. The author has included a
|
||||
safety feature in case you misplace the original program source:</p>
|
||||
<div class="sourceCode" id="cb10"><pre
|
||||
class="sourceCode sh"><code class="sourceCode bash"><span id="cb10-1"><a href="#cb10-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./sorter</span> <span class="at">-r</span> 0 0 0 0 <span class="op"><</span> sorter.c <span class="op">></span> theorem_bkp.c</span></code></pre></div>
|
||||
<p>And finally, as a special offer to users of this entry, the author
|
||||
provides a Fibonacci sequence generator! Try:</p>
|
||||
<div class="sourceCode" id="cb11"><pre
|
||||
class="sourceCode sh"><code class="sourceCode bash"><span id="cb11-1"><a href="#cb11-1" aria-hidden="true" tabindex="-1"></a><span class="ex">./sorter</span> 0 0 0 0 <span class="op"><</span> theorem.c <span class="op">></span> fibonacci.c</span>
|
||||
<span id="cb11-2"><a href="#cb11-2" aria-hidden="true" tabindex="-1"></a><span class="fu">make</span> fibonacci</span>
|
||||
<span id="cb11-3"><a href="#cb11-3" aria-hidden="true" tabindex="-1"></a><span class="ex">./fibonacci</span> 1 1</span>
|
||||
<span id="cb11-4"><a href="#cb11-4" aria-hidden="true" tabindex="-1"></a><span class="ex">./fibonacci</span> 2 1</span></code></pre></div>
|
||||
<p>NOTE: if the two args passed to <code>fibonacci</code> and
|
||||
<code>theorem_bkp</code> add to 0 it will print 0 over and over again in
|
||||
an infinite loop. In this case it should not be fixed (another condition
|
||||
where this occurred was fixed in 2023 as it affected usability of the
|
||||
program).</p>
|
||||
<p>Program available on 9 track and cartridge cassette. Neither <a
|
||||
href="https://ginsu.com">Ginsu knife</a> nor <a
|
||||
href="https://en.wikipedia.org/wiki/Swiss_Army_knife">Swiss army
|
||||
knife</a> included! :-)</p>
|
||||
<p>When this program was first shown at the 1990 Summer USENIX
|
||||
conference, it received a standing ovation; a first for a contest
|
||||
entry.</p>
|
||||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||||
<p>Differential equations are solved via the Runge-Kutta method, which
|
||||
guarantees local error proportional to <code>h^5</code>, and total error
|
||||
across a finite interval is at most a constant times
|
||||
<code>h^4</code>.</p>
|
||||
<p>Sorting is accomplished with a standard <a
|
||||
href="https://en.wikipedia.org/wiki/Shellsort">shell sort</a>.</p>
|
||||
<p>Note that the sorting and reversing is limited to files with fewer
|
||||
than 500 lines, each less than 99 characters long.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>If you would rather “Daisy” someone other than Westley, rename the
|
||||
program as needed. :-)</p>
|
||||
<p>Read each block of code as if it were a piece of correspondence. For
|
||||
example, the first block of code would read:</p>
|
||||
<pre><code>charlie,
|
||||
doubletime me, OXFACE!
|
||||
not interested, get out
|
||||
mainly die, charly, *die*
|
||||
signed charlotte</code></pre>
|
||||
<p>The original source had control-L’s after each code block. To make it
|
||||
easier on news readers, we converted each control-L to a blank line.</p>
|
||||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||||
<p>This is a “Picking the Daisy” simulation. Now, instead of mangling a
|
||||
daisy, simply run this program with the number of petals desired as the
|
||||
argument.</p>
|
||||
<p>This is a good counter-example to peoples’ complaints that C doesn’t
|
||||
have an “English-like” syntax.</p>
|
||||
<p>Lint complains about everything - null effect, xxx may be used before
|
||||
set, statement not reached, return(e) and return. Lint dumps core on
|
||||
some systems. My personal favorite lint complaint is</p>
|
||||
<p><strong><em>“warning: eroticism unused in function
|
||||
main”.</em></strong></p>
|
||||
<p>Also obviously, <code>(char)lotte</code> and <code>(char*)lie</code>
|
||||
are incompatible types…</p>
