Here’s a way to augment all functions in the global namespace with the function of your choice:
function augment(withFn) {
var name, fn;
for (name in window) {
fn = window[name];
if (typeof fn === 'function') {
window[name] = (function(name, fn) {
var args = arguments;
return function() {
withFn.apply(this, args);
return fn.apply(this, arguments);
}
})(name, fn);
}
}
}
augment(function(name, fn) {
console.log("calling " + name);
});
One down side is that no functions created after calling augment
will have the additional behavior.
