Is there some other way I'm not thinking of, kind of a beginner here. any syntactical help would also be appre...
I have inherited an existing code base where the "features" are as follows: huge monolithic classes with (literally) 100's of member variables and methods that go one for pages (er. screens) public and private methods with a large number of arguments.

I have the code (inside one object) onclick: this._addX.bind(this) and then inside another object onclick: this._addY.bind(this) Now, _addX() and _addY are nearly identical, except they both end up calling (on the click event) a function with different argument values, say _addX calls foo('x') and _addY calls foo('y'). So I tried: ...
Hello, I'm very new to ruby and I'm trying to write a web application using the rails framework. Through reading I've seen methods being called like this: some_method "first argument", :other_arg => "value1", :other_arg2 => "value2" Where you can pass an unlimited number of arguments.

I don't know if this is possible, but in some of my unit tests, I end up initializing different objects with the same arguments.

Ok, I guess that this is a very absurd/basic question, but still: class m { public: void f(int ***); /***/ } void m::f(int ***a = NULL) { /***/ } The call to f (as well as any function which has default values for all the arguments) doesn't accept 0 arguments.
