Tricks for including files

Some tricks with the include() function...

Including a file if some other file not loaded

You can use this trick to create mods for your mods. A basic approach can be done using just the include() function and nothing else...

Basic approach to loading defaults if alternate not found...

if (include("path/to/mymod.custom.js") === false) { // not found
  include("path/to/mymod.default.js"); // load default settings
}

But, assuming you're starting to use dependencies, you might want a more robust approach...

Use dependency checking to load file and check it initialised...

include("path/to/util.js");
 
Check.paths = ["path/to/mymod"]; // enable autoloading
if (!Check.has(".custom.js")) { // path/to/mymod.custom.js
	Check.load(".default.js");  // path/to/mymod.default.js
}

The obvious problem here is that you might have dependencies that rely on "mymod.default.js", but if "mymod.custom.js" gets loaded instead those dependencies will break.

The solution to this is to provide a fake file in both "mymod.default.js" and "mymod.extend.js" and then use that for dependency checks:

Fake provide in mymod.default.js and mymod.extend.js

// use this if you want to check which settings were loaded...
Check.provide(self);
 
// use this for general dependency checks...
Check.provide({
	file: "settings.loaded",
	ver : self.ver
});

Dependency Descriptor Object — Define one or more dependencies for your script...
Check() — Perform a soft-check to see if a dependency is available...
- Check.basePath — The base path to the folder that contains the APIs folder...
- Check.paths[] — Define one or more folder paths to enable autoloading...
- Check.doWhen() — Perform a task when dependencies become available.
- Check.has() — Check if a dependency is available, try and load it if not, return availability state...
- Check.LAZY_LOAD — Disable autoloading during a dependency check...
- Check.required() — Thrown a descriptive error if dependency check fails...
- Check.NOT_LOADED — Indicates a script is not yet loaded, or must not be loaded, depending on the Check function being used...
- Check.ANY_VERSION — Skip version checking for a dependency check...
- Check.provide() — Indicate a file is now available.
- Check.versionOf() — Check the version of a dependency.
