Typo fixes and change 'download entry source' to 'download entry' as it's the tarball, not the source itself. Rebuilt .entry.json and index.html files for all entries.

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||
<p>Polyglots have come and gone, but this was the first one we’d seen
|
||
where one language <em>used</em> another to perform its tasks. An interesting
|
||
approach. Admittedly, it’s not all that obfuscated - but there’s more
|
||
to it than you might think, since you have to make sure that your
|
||
changes don’t change the shell code or the Makefile.</p>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<h3 id="summary">Summary</h3>
|
||
<p>This program works as a C source file, a Makefile and also as a shell
|
||
(<code>/bin/sh</code>) script. But unlike some other multi-language programs, this one is
|
||
NOT meant to print <code>Hello, world</code> in all 3 cases (At least in the true sense
|
||
;-)). The C, Makefile and shell code build upon each other to create a C program (?)
|
||
which when executed as a shell script will compile itself through the C compiler
|
||
using a Makefile! - Pretty useful, Eh?</p>
|
||
<p>Probably, this is the first entry ever to fully satisfy Rule #1 (“Your entry
|
||
must be a complete program”) in the strictest sense;-)</p>
|
||
<h3 id="top-5-reasons-imho-why-this-code-is-an-entry-for-ioccc">Top 5 reasons (IMHO) why this code is an entry for IOCCC</h3>
|
||
<ol type="1">
|
||
<li><p>A glance at the source itself will tell you that most of the
|
||
Obfuscation is NOT in the C code per se, but in the comments
|
||
to the C code. (But sadly, I could not find an “International
|
||
Obfuscated C COMMENT contest”. So I HAD to send this entry
|
||
here to the IOCCC itself).</p></li>
|
||
<li><p>Of the 3 languages in the source, the least obfuscated is
|
||
C (But again, there was NO obfuscated make/shscript contest)
|
||
(Does this hint for a rule in IOCCC-2001 that the major
|
||
obfuscation should be in C and not elsewhere???. Mmmmm…).</p></li>
|
||
<li><p>Extending Argument #2… Obfuscation done in the C code
|
||
(comments?) creates obfuscated code for the other 2 languages.
|
||
This opens new possibilities to be explored in depth in future
|
||
<code>IOCCC</code>s.</p></li>
|
||
<li><p>LOOKS like a Makefile, WORKS like a shell script and COMPILES
|
||
like a C program.</p></li>
|
||
<li><p>Does something useful (See Notes #1 and #2 below).</p></li>
|
||
</ol>
|
||
<h3 id="notes">Notes</h3>
|
||
<ol type="1">
|
||
<li>The program could have been something other than the simple “Hello, world”
|
||
program that it is. It is possible to do <code>#include "prog2.c"</code> in the place of
|
||
the <code>main()</code>, leaving the complexities of the C file elsewhere and making this
|
||
source still acceptable to <code>make</code> and <code>sh</code>. The following modification to the
|
||
last few lines will compile the IOCCC’s famous <a href="mkentry.c">mkentry.c</a>.</li>
|
||
</ol>
|
||
<pre><code>.PHONY: /* true clean */
|
||
#undef true
|
||
#include "mkentry.c"</code></pre>
|
||
<p>Ain’t that useful?</p>
|
||
<ol start="2" type="1">
|
||
<li><p>By extending this program’s idea, It is possible to do some
|
||
very interesting things like generating C code on execution
|
||
by adding additional code in make/sh (open up a loop????).
|
||
This opens the possibilities of generating & compiling some
|
||
(obfuscated?) C code. (Maybe should try this if this program
|
||
fails at IOCCC 2000)</p></li>
|
||
<li><p>Changing the <code>%:%.c</code> dependency to a <code>$(PROG):$(PROG).c</code> form
|
||
can compile this program with some other <code>make</code>s (I got it to
|
||
work in Windows using nmake and Gnuwin32’s sh ;-) )</p></li>
|
||
<li><p>Interesting things to do: try <code>./tomx.c clean</code>. This will
|
||
do the same as <code>make clean</code> :-)). Also: <code>./tomx.c all</code></p></li>
|
||
<li><p>Be careful about the tabs in the source code. Removing them
|
||
or converting tabs to spaces can be disastrous.</p></li>
|
||
