Allowed globals is incomplete? #181

Open jrchamp opened 2 months ago

In short, the $FULLSCRIPT global is missing from the list of allowed variable names.

As of August 22, 2024, here are the allowed globals: https://github.com/moodlehq/moodle-cs/blob/89ff0acd727f8611cbafe5aea524614090b24ad9/moodle/Sniffs/NamingConventions/ValidVariableNameSniff.php#L32-L37

While I see the PHP superglobals ($_GET, $_POST, etc.) and the main Moodle global objects ($CFG, $DB, $USER, etc.) there are a few Moodle global literals like $ME, $FULLME, $SCRIPT that are present.

Today was my first day seeing those literals, because I was looking for origin of $FULLSCRIPT. I don't know the difference between the four and I don't see any uses in core of $FULLSCRIPT outside of it being defined and initialized. Someone else didn't know, so they incorrectly lowercased the variable thinking that it was a plugin-specific variable, which may have caused some issues.

Side note: If any of the Moodle globals are "deprecated" or there are better options, documentation would be really helpful. ❤️
