- /**
- * Secure replacement for PHP built-in function htmlspecialchars().
- *
- * See ticket #427 (http://wush.net/trac/wikka/ticket/427) for the rationale
- * for this replacement function.
- *
- * The INTERFACE for this function is almost the same as that for
- * htmlspecialchars(), with the same default for quote style; however, there
- * is no 'charset' parameter. The reason for this is as follows:
- *
- * The PHP docs say:
- * "The third argument charset defines character set used in conversion."
- *
- * I suspect PHP's htmlspecialchars() is working at the byte-value level and
- * thus _needs_ to know (or asssume) a character set because the special
- * characters to be replaced could exist at different code points in
- * different character sets. (If indeed htmlspecialchars() works at
- * byte-value level that goes some way towards explaining why the
- * vulnerability would exist in this function, too, and not only in
- * htmlentities() which certainly is working at byte-value level.)
- *
- * This replacement function however works at character level and should
- * therefore be "immune" to character set differences - so no charset
- * parameter is needed or provided. If a third parameter is passed, it will
- * be silently ignored.
- *
- * In the OUTPUT there is a minor difference in that we use ''' instead
- * of PHP's ''' for a single quote: this provides compatibility with
- * get_html_translation_table(HTML_SPECIALCHARS, ENT_QUOTES)
- * (see comment by mikiwoz at yahoo dot co dot uk on
- * http://php.net/htmlspecialchars); it also matches the entity definition
- * for XML 1.0
- * (http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_Special_characters).
- * Like PHP we use a numeric character reference instead of ''' for the
- * single quote. For the other special characters we use the named entity
- * references, as PHP is doing.

+ * Secure replacement for PHP built-in function htmlspecialchars().
+ *
+ * See ticket #427 (http://wush.net/trac/wikka/ticket/427) for the rationale
+ * for this replacement function.
+ *
+ * The INTERFACE for this function is almost the same as that for
+ * htmlspecialchars(), with the same default for quote style; however, there
+ * is no 'charset' parameter. The reason for this is as follows:
+ *
+ * The PHP docs say:
+ * "The third argument charset defines character set used in conversion."
+ *
+ * I suspect PHP's htmlspecialchars() is working at the byte-value level and
+ * thus _needs_ to know (or asssume) a character set because the special
+ * characters to be replaced could exist at different code points in
+ * different character sets. (If indeed htmlspecialchars() works at
+ * byte-value level that goes some way towards explaining why the
+ * vulnerability would exist in this function, too, and not only in
+ * htmlentities() which certainly is working at byte-value level.)
+ *
+ * This replacement function however works at character level and should
+ * therefore be "immune" to character set differences - so no charset
+ * parameter is needed or provided. If a third parameter is passed, it will
+ * be silently ignored.
+ *
+ * In the OUTPUT there is a minor difference in that we use ''' instead
+ * of PHP's ''' for a single quote: this provides compatibility with
+ * get_html_translation_table(HTML_SPECIALCHARS, ENT_QUOTES)
+ * (see comment by mikiwoz at yahoo dot co dot uk on
+ * http://php.net/htmlspecialchars); it also matches the entity definition
+ * for XML 1.0
+ * (http://www.w3.org/TR/xhtml1/dtds.html#a_dtd_Special_characters).
+ * Like PHP we use a numeric character reference instead of ''' for the
+ * single quote. For the other special characters we use the named entity
+ * references, as PHP is doing.

Plugin Name: WP-Syntax
Plugin URI: http://wordpress.org/extend/plugins/wp-syntax/
Description: Syntax highlighting using <a href="http://qbnz.com/highlighter/">GeSHi</a> supporting a wide range of popular languages. Wrap code blocks with <code><pre lang="LANGUAGE" line="1"></code> and <code></pre></code> where <code>LANGUAGE</code> is a geshi supported language syntax. The <code>line</code> attribute is optional.
