Much like the other lists I created here, this will list Exchange functions.

list-functions.php

<?php

$GLOBALS['functions'] = array();

function list_theme_functions( $directory ) {
	global $functions;
	
	$files = array_diff( scandir( $directory ), array( '.', '..', '_list-files.php', '_list-hooks.php', '_get-contents.php', '.DS_Store', 'nonce.php', '_list-hooks-duplicates.php', '_list-functions.php' ) );
	
	foreach ( $files as $file ) {
		if ( dirname( __FILE__ ) == $directory ) {
			if ( is_dir( $directory . '/' . $file ) ) {
				$folder = $file . '.php';
			}
			if ( $folder != $file ) {
				if ( is_dir( $file ) ) {
					if ( preg_match_all( "|" . preg_quote( 'it_exchange(' ) . "(.*?)\)|", file_get_contents( dirname( __FILE__ ) . '/' . $file . '.php' ), $matches ) ) {
						$actions = str_replace( '	', '', str_replace( '<?php ', '', str_replace( ');', ')', $matches[0] ) ) );
						
						foreach ( $actions as $action ) {
							$action = explode( '\'', $action );
							// echo '*[[Exchange_Theme_API:_' . $action[1] . '_(' . $action[3] . ')|it_exchange( \'' . $action[1] . '\', \'' . $action[3] . '\' )]]' . "\n";
							
							$functions[$action[1]][$action[3]] = '*[[Exchange_Theme_API:_' . $action[1] . '_(' . $action[3] . ')|it_exchange( \'' . $action[1] . '\', \'' . $action[3] . '\' )]]';

foreach ( $functions as $context => $tag ) {
	echo "\n===" . ucwords( str_replace( '-', ' ', $context ) ) . "===\n";
