API

Context

Create an instance of Context.

.setContext

Add a context level, optionally passing a value to start with.

• name {String}: The name of the context to add.
• level {Number}: Numerical value representing the order in which this level should be merged versus other lvl.
• value {Object}: Optionally pass an object to start with.

context.setContext('locals', {a: 'b'});

.getContext

Get the raw (un-merged) context for name.

• name {String}: The context to get.
• returns: {*}

context.setContext('a', {a: 'b'});
context.getContext('a');
// => {a: 'b'}

.extendContext

Extend context name with the given value

• name {String}
• key {String}
• value {Object}
• returns: {String}

context.setContext('locals', {a: 'b'});

.setLevel

Set the level for a context. This determines the order in which the context will be merged when .calculate() is called.

• name {String}: The name of the context.
• level {Number}: The level (number) to set for the level.

if (foo) {
  context.setLevel('locals', 10);
} else {
  context.setLevel('locals', 0);
}

.calculate

Calculate the context, optionally passing a callback fn for sorting. (Note that sorting must be done on levels, not on the context names).

• keys {String|Array}: Key, or array of keys for context levels to include.
• fn {Function}: Sort function for determining the order of merging.

app.calculate(['a', 'b'], function(a, b) {
  return app.lvl[a] - app.lvl[a];
});

.resetContexts

Clear all contexts.
