Created `quick-start.md` to hold the FAQ 0.0 content. Used `sgit(1)` to change: * faq.html#enter ==> quick-start.html#enter * faq.html#enter_questions ==> quick-start.html#enter_questions * faq.html#step_0 ==> quick-start.html#step_0 * faq.html#step_1 ==> quick-start.html#step_1 * faq.html#step_2 ==> quick-start.html#step_2 * faq.html#register ==> quick-start.html#register * faq.html#step_3 ==> quick-start.html#step_3 * faq.html#step_4 ==> quick-start.html#step_4 * faq.html#step_5 ==> quick-start.html#step_5 * faq.html#step_6 ==> quick-start.html#step_6 * faq.html#step_7 ==> quick-start.html#step_7 * faq.html#step_submit ==> quick-start.html#step_submit Via: ```sh sgit -e 's/faq\.html#enter/quick-start.html#enter/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#enter_questions/quick-start.html#enter_questions/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#step_0/quick-start.html#step_0/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#step_1/quick-start.html#step_1/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#step_2/quick-start.html#step_2/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#register/quick-start.html#register/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#step_3/quick-start.html#step_3/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#step_4/quick-start.html#step_4/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#step_5/quick-start.html#step_5/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#step_6/quick-start.html#step_6/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#step_7/quick-start.html#step_7/g' '*.md' '*.hdr' 'inc/*.html' sgit -e 's/faq\.html#step_submit/quick-start.html#step_submit/g' '*.md' '*.hdr' 'inc/*.html' ``` The former FAQ 0.0 section in `faq.html` now just refers to `quick-start.html`. Modified menu and non-JS menu so that "Enter the IOCCC" refers to `quick-start.html`. Changed `bin/gen-top-html.sh` VERSION from "1.4.10 2024-11-23" to "1.4.11 2025-01-09". Performed `make www` on macOS to complete the above.

<p>The second command, <code>./tromp 10 "hkl jq"</code>, will set up the keys kind of like

vim:</p>
|

<ul>
|

<li>h - left (left)</li>

<li>k - rotate (up)</li>

<li>space - pause (space)</li>

<li>q - quit (:q)</li>
|

</ul>
|
||
<p><strong>NOTE</strong>: after the game ends a file called <code>HI</code> will be in the directory with the
|
||
high scores (up to 20 runs saved) so one can see who has the highest score. The
|
||
file might look like:</p>
|
||
<pre><code> 330 by luser
|

136 by loser
|
||
100 by winner</code></pre>

<p>… or so, where in this case the <a href="https://web.archive.org/web/20181023221954/https://www.chicagotribune.com/news/ct-xpm-2002-07-31-0207310310-story.html">luser is the winner, the loser is in second

||
<h3 id="alternate-use">Alternate use:</h3>
|
||
<p>Use <code>tromp.alt</code> as you would <code>tromp</code> above.</p>
|
||
<p><strong>NOTE</strong>: testing more than one user updating the high score file, one of the
|
||
benefits of the alt version, has not been done.</p>
|
||
<p>The original unmodified alternate code, which will no longer work right if it
|
||
even compiles, is provided later in the author’s remarks.</p>
|
||
<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||
<p>This is a character terminal version of the <code>TETRIS</code> game.
|
||
It runs on a VT100 compatible terminal or emulator. It is
|
||
best used at 4800 baud or more.</p>
|
||
<p>By default, <code>drops_per_sec</code>, the number of times a tetrimino
|
||
will drop in a second, is 2. The default <code>cmd_string</code> is
|
||
<code>jkl pq</code>. The first 6 characters of <code>cmd_string</code> relate
|
||
to the following 6 game commands:</p>
|
||
<ul>
|
||
<li>j - left</li>
|
||
<li>k - rotate</li>
|
||
<li>l - right</li>
|
||
<li>space - drop</li>
|
||
<li>p - pause</li>
|
||
<li>q - quit</li>
|
||
</ul>
|
||
<p>Specifying <code>cmd_string</code> allows one to redefine the commands.
|
||
The pause command pauses the game, clears the screen and
|
||
prints the current score. To resume, type the pause
|
||
character again, which by default is <code>p</code>.</p>
|
||
<p>As was stated last year, we are likely to be more strict about
|
||
portability in the future. [ We mean it this time :-) ]</p>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<p>This program plays the familiar game of <code>TETRIS</code> with the
|
||
following features:</p>
|
||
<ul>
|
||
<li><p>outputs vt100-like escape-sequences for cursor
|
||
positioning and normal/reverse video in curses
|
||
like fashion (minimal output for screen updates)</p></li>
|
||
<li><p>continuously increasing speed (except in pause)</p></li>
|
||
<li><p>start speed selectable by giving <code>n</code> as first argument,
|
||
where <code>n</code> is the number of drops per second (default=2).</p></li>
|
||
<li><p>controls also selectable by giving as the second argument
|
||
a string of 6 characters. By default they are <code>jkl pq</code>.</p></li>
|
||
<li><p>screen is blanked during the pause and the score is shown</p></li>
|
||
<li><p>maintains a high-score table</p></li>
|
||
</ul>
|
||
<p>Giving a full path name for the table will result in a
|
||
system-wide high-score allowing a competition between users.</p>
|
||
<h3 id="additional-remarks-from-the-judges">Additional remarks from the judges:</h3>
|
||
<p>The author provided us with the following notes and new version of
|
||
the program:</p>
|
||
<blockquote>
|
||
<p>Here is a somewhat improved version of my tetris entry. All the changes are
|
||
in the <code>popen(3)</code> at the end. Formerly a move was done to the HI score file
|
||
which is not permitted for other users. Now other users can change the <code>HI</code>
|
||
score file. The extra option <code>-m</code> is passed to sort, so that it knows that its
|
||
input files are already sorted. The <code>-o</code> output option of sort is used instead
|
||
of a temporary file.</p>
|
||
<p>You may also want to consider giving just the raw option to <code>stty</code> at the
|
||
start and <code>-raw</code> at the end. This further reduces the size of the program, but
|
||
has the possible disadvantage that the program can only by stopped by ‘q’ or by
|
||
the <code>kill -9</code> command.</p>
|
||
