Moodle 2.0


This document has for goal to defined a libraries structure to avoid to end up with a mess of functions everywhere into Moodle.

We suggest that we split library functions into two files, one lib.php that contains all library functions that can be called by external applications and one locallib.php that contains all functions that are internal to Moodle core.

Structure

There are several standard locations for library code in Moodle.

Simple core library

If the widget feature is a very simple core librray with no GUI scripts (like formslib) then do it like this:

lib/widgetlib.php

This contains the main library functions. New ones should always implement these as a class.

lib/widget

Any supporting files for this library can go in this subdirectory. This directory should not contain any GUI scripts and files from here should NOT be directly included in Moodle code.

Complex core library or plugin module

If the feature has some GUI scripts then it should have its own directory (eg like blog, comment, mod/forum, local/widget etc) and then this is always applies:

widget/locallib.php

for functions and classes that will only be used by scripts in widget directory. Generally there will be no capability checks in these functions.

widget/lib.php

the main library file for the module containing functions that are either required by core code (eg forum_cron()), or simply being made available to other Moodle code (eg comment/lib.php). Generally there will be no capability checks in these functions.

widget/externallib.php

for functions and classes implementing external interface for use by third-party systems like web services, and may also be used by other modules in Moodle. These functions are a very stable API and implement full capability checking.

Refatoring of old code
