I have added the ability to use entirely custom piece sets in a game. These are defined in GAME Code and do not use an external PHP file. Here is some sample code I wrote:

// A demo of using multiple internal sets that do not match any set file.

// Name the sets you will use by assigning them to the $groupsets array.
// Use capitalized names for the sets. These do not match any file names.
setsystem groupsets array Abstract Alfaerie AlfaeriePNG Magnetic Motif;

// Define pieces in an array variable called mypieces.
// Start by creating an associative array of all pieces shared in common.
// The key should be a label, and the value should be a filename.
// A single line of code is broken into multiple lines of text for legibility.
set mypieces assoc 
  K "WKing.gif"   k "BKing.gif" 
  Q "WQueen.gif"  q "BQueen.gif" 
  R "WRook.gif"   r "BRook.gif" 
  B "WBishop.gif" b "BBishop.gif" 
  N "WKnight.gif" n "BKnight.gif" 
  P "WPawn.gif"   p "BPawn.gif";

// Set the $dir system variable to match the set, and modify filenames as needed.
if == pieceset Alfaerie:
  setsystem dir "/graphics.dir/alfaerie/";
  foreach (k v) #mypieces:
    setelem mypieces #k tolower #v;
  next;
elseif == pieceset AlfaeriePNG:
  setsystem dir "/graphics.dir/alfaeriePNG/";
  foreach (k v) #mypieces:
    setelem mypieces #k tolower str_replace .gif .png #v;
  next;
elseif == pieceset Magnetic:
  setsystem dir "/graphics.dir/magnetic/";
elseif == pieceset Motif:
  setsystem dir "/graphics.dir/motif/";
else:
  // Have a default set for when the set does not match any allowed set.
  // The default is Abstract.
  setsystem dir "/graphics.dir/abstract/";
endif;

// Now that the pieces are defined, copy the #mypieces array to $pieces
setsystem pieces #mypieces;

Quick Markdown Guide

By default, new comments may be entered as Markdown, simple markup syntax designed to be readable and not look like markup. Comments stored as Markdown will be converted to HTML by Parsedown before displaying them. This follows the Github Flavored Markdown Spec with support for Markdown Extra. For a good overview of Markdown in general, check out the Markdown Guide. Here is a quick comparison of some commonly used Markdown with the rendered result:

Top level header: <H1>

Block quote

Second paragraph in block quote

First Paragraph of response. Italics, bold, and bold italics.

Second Paragraph after blank line. Here is some HTML code mixed in with the Markdown, and here is the same <U>HTML code</U> enclosed by backticks.

Secondary Header: <H2>

  • Unordered list item
  • Second unordered list item
  • New unordered list
    • Nested list item

Third Level header <H3>

  1. An ordered list item.
  2. A second ordered list item with the same number.
  3. A third ordered list item.
Here is some preformatted text.
  This line begins with some indentation.
    This begins with even more indentation.
And this line has no indentation.
