Moodle -- Local Folder -- hookutils

Hookutils is a moodle 1.9.x library (that lives in the Moodle local folder) that provides a consistent programming pattern for customizing core Moodle code:


if override_with_error(methods[], local_folder_files[]) {

// as little setup as possible
method1();
method2();

} else {

// overriden upstream code remains harmlessly here

}

Three methods are provided: override_with_exception, override_with_error, and override_without_error.

The idea was to minimize the amount of code that needs to be rewritten every time your Moodle instance is updated.
