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.

<p>What happens if you use something other than valid digits?</p>
|
||||
<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||||
<p>The octal expression may contain:</p>
|
||||
<pre><code>unary operators: +, -
|
||||
binary operators +, -, *, /, %
|
||||
hex numbers: x or X followed by hex digits
|
||||
decimal numbers: d or D followed by decimal digits
|
||||
octal numbers: octal digits
|
||||
grouping: ()</code></pre>
|
||||
<p>No spaces are allowed in the expression. To avoid shell expansion,
|
||||
one should surround the expression in single quotes.</p>
|
||||
<p>It is a good thing that this program consists of only one expression,
|
||||
otherwise it might become hard to understand. :-)</p>
|
||||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||||
<p>The program does no error checking - erroneous expressions will
|
||||
produce spurious results. Note that unary <code>-</code> is an operator.
|
||||
Thus, decimal <code>-46</code> would be entered as <code>-d46</code> and
|
||||
not <code>d-46</code>.</p>
|
||||
<h3 id="what-makes-this-program-special">What Makes This Program
|
||||
Special:</h3>
|
||||
<ol start="0" type="1">
|
||||
<li><p>Of course, the fact that the program takes input and produces
|
||||
output in octal, rather than a more useful system like decimal, makes it
|
||||
“special”.</p></li>
|
||||
<li><p>The entire program consists of a single expression, returned from
|
||||
<code>main()</code>.</p></li>
|
||||
<li><p>There are no global or local variables other than the parameters
|
||||
to <code>main()</code>.</p></li>
|
||||
<li><p>All of the constants in the program are expressed in octal -
|
||||
including the <code>printf(3)</code> string.</p></li>
|
||||
<li><p>The variables are given names which cause visual confusion with
|
||||
the octal constants.</p></li>
|
||||
<li><p>The program is formatted like a Roman numeral 8. The significance
|
||||
of 8 is obvious. I chose Roman numerals because it is a numbering system
|
||||
even more arcane than octal. It’s not very ‘deceptive’, but it’s
|
||||
difficult to deceptively format a program which has no explicit control
|
||||
structures (other than <code>?:</code>s).</p></li>
|
||||
<li><p>Many simple tasks are done many times. I tried to do these
|
||||
differently each time, to make the program harder to
|
||||
understand.</p></li>
|
||||
</ol>
|
||||
<h3 id="how-it-works">How It Works:</h3>
|
||||
<p>It’s a recursive descent parser, calling <code>main()</code> for all
|
||||
of its recursion. <code>O2</code> is a state variable, telling
|
||||
<code>main()</code> what grammar non-terminal to parse.
|
||||
<code>**O7</code> is the next character. <code>O3</code> is an
|
||||
intermediate result. Whenever you see a construct like:</p>
|
||||
<pre><code>!(expression with O2)?</code></pre>
|
||||
<p>it’s decrementing and testing <code>O2</code> to see what state it’s
|
||||
in. Comparisons involving <code>**O7</code> and octal constants are
|
||||
looking for certain characters.</p>
|
||||
<p>Here’s the grammar (<code>'e'</code> denotes the empty string) :</p>
|
||||
<pre><code><E> ::= <T><E'>
|
||||
<E'> ::= +<T><E'> | -<T><E'> | e
|
||||
<T> ::= <F><T'>
|
||||
<T'> ::= *<F><T'> | /<F><T'> | %<F><T'> | e
|
||||
<F> ::= +<F> | -<F> | (<E><C> | d<D> | D<D> | x<X> | X<X> | <O>
|
||||
<C> ::= )
|
||||
<D> ::= [0-9]<D> | e
|
||||
<X> ::= [0-9]<X> | [A-F]<X> | [a-f]<X> | e
|
||||
<O> ::= [0-7]<O> | e</code></pre>
|
||||
<p>Here’s how the grammar nonterminals map to octal state numbers:</p>
|
||||
<pre><code><E> is 012
|
||||
<E'> is 011
|
||||
<T> is 010
|
||||
<T'> is 07
|
||||
<F> is 06
|
||||
<C> is 013
|
||||
<D> is 04
|
||||
<X> is 05
|
||||
<O> is 03</code></pre>
|
||||
<p>Here’s a version of the program before it got formatted into the
|
||||
VIII, augmented with comments showing where each state begins.
|
||||
<code>N1</code> and <code>N2</code> are notes:</p>
