4 * A configurator intended to read its config from a PHP-style INI file,
5 * instead of a PHP file.
7 * Pass a filename to the IniConfig() function and it will read all its
8 * definitions from there, all by itself, and proceed to do a mass-define
9 * of all valid PHPWiki config items. In this way, we can hopefully be
10 * totally backwards-compatible with the old index.php method, while still
11 * providing a much tastier on-going experience.

38 * - Convert the value lists to provide defaults, so that every "if
39 * (defined())" and "if (!defined())" can fuck off to the dismal hole
41 * - config.ini => config.php dumper for faster startup. (really faster? to time)
44 * - Old-style index.php => config/config.ini converter.
46 * - Don't use too much globals for easier integration into other projects
47 * (namespace pollution). (FusionForge, phpnuke, postnuke, phpBB2, carolina, ...)
48 * Use one global $phpwiki object instead which holds the cfg vars, constants
49 * and all other globals.
50 * (global $FieldSeparator, $charset, $WikiNameRegexp, $KeywordLinkRegexp;
51 * global $DisabledActions, $DBParams, $LANG, $AllActionPages)
53 * - Resurrect the larger "config object" code (in config/) so it'll aid the
54 * GUI config writers, and allow us to do proper validation and default
57 * - Get rid of WikiNameRegexp and KeywordLinkRegexp as globals by finding
58 * everywhere that uses them as variables and modify the code to use
62 include_once (dirname(__FILE__) . "/config.php");
63 include_once (dirname(__FILE__) . "/FileFinder.php");
66 * Speed-up iniconfig loading.
68 * Dump the static parts of the parsed config/config.ini settings to a fast-loadable config.php file.
69 * The dynamic parts are then evaluated as before.
70 * Requires write-permissions to config/config.php
