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

file location

if you are writing a module (like workshop) => mod/folder/lib.php and mod/folder/locallib.php
if you are writing something more general and there is a folder in relation (like comments, user, group,...) => folder/lib.php
if you are writing something more general and there is no folder in relation => lib/namelib.php

file content structure

lib.php

It contains code that can be called all over Moodle core.
Some devs continues to write xxx/lib.php or lib/xxxlib.php with procedural functions.
Some devs did some work (committed, working on , in specs) with xxx/lib.php or lib/xxxlib.php being a class.

locallib.php

It contains code that can be called all over Moodle core.
You should write it the best you can => no recommandation yet
We can see a tendency that new module locallib.php will likely contain class when refactored locallib.php will likely be a procedural functions...

externallib.php

It contains code that can be called by external applications. The functions are not supposed to be called by our core scripts.
The functions include capability check.

Refatoring of old code
