// The Module object: Our interface to the outside world. We import |
|
// and export values on it. There are various ways Module can be used: |
|
// 1. Not defined. We create it here |
|
// 2. A function parameter, function(Module) { ..generated code.. } |
|
// 3. pre-run appended it, var Module = {}; ..generated code.. |
|
// 4. External script tag defines var Module. |
|
// We need to check if Module already exists (e.g. case 3 above). |
|
// Substitution will be replaced with actual code on later stage of the build, |
|
// this way Closure Compiler will not mangle it (e.g. case 4. above). |
|
// Note that if you want to run closure, and also to use Module |
|
// after the generated code, you will need to define var Module = {}; |
|
// before the code. Then that object will be used in the code, and you |
|
// can continue to use Module afterwards as well. |
