Suppose you have this pseudo-code do_something(); function do_something(){ print "I am saying hello."; } Why do some programming languages require the call to do_something() to appear below the function declaration in order for the code to run? ...
For some reason ss.transition() does not affect the appropriate DOM elements after ss.goTo() is triggered by an onclick. The ss.transition() call under //Init does work as expected. I assume this is a scope problem. Little help? var ss = {}; ss.goTo = function(i) { ss.old = ss.current; ss.current = ss.slides[i]; ss.transiti...
I'm defining a lot of flows and each of my flows has a lot of actions within its states. The namespace seems to be getting fairly crowded now, so I'm wondering if it's possible to define the spring beans for flow actions from within the flow.xml or some other way such that it's visible to the flow, but not to other flows, but still has...
Hi, Basically I am trying to understand and learn the 'this' keyword's working principle in JavaScript. As far as I understand 'this' refers to the object (function) that it is inside at that moment. So, by believing this, I wanted to test the output of the simple code below: <body> <input type="button" value="Add Age" onclick="Ou...
I fear I may be losing my marbles today, because I don't know how to do what I want to. I want a custom prompt that I can call from any of my other JavaScript functions. I don't know how to get this work, even though it feels like I've done it a hundred times. Here is an example var modal = function() { var prompt = function(msg) ...

I frequently find myself using the following pattern for string formatting. a = 3 b = 'foo' c = dict(mykey='myval') #prints a is 3, b is foo, mykey is myval print('a is {a}, b is {b}, mykey is {c[mykey]}'.format(**vars())) That is, I often have the values I need to print in the local namespace, represented by a call to vars(). As I l...
Hi, I am having an issue trying to figure out var scoping on xslt. What I actually want to do it to ignore 'trip' tags that have a repeated 'tourcode'. Sample XML: <trip> <tourcode>X1</tourcode> <result>Budapest</result> </trip> <trip> <tourcode>X1</tourcode> <result>Budapest</result> </trip> <trip> <tourcode>X1</tourcode> <resul...
Hi, I'd like to define a binary operator on in the global namespace. The operator works on a class that is defined in another namespace and the operator should get access to the private members of that class. The problem I have is that I don't know how to scope that global operator when making it a friend in the class definition. I tri...

Is there anyway to for an included file to be used in a parent scope to the one it was called in? The following example is simplified, but does the same job. In essence, a file will be included by a function, but would like the scope of the included file to be the scope of where the function that included it was called from. main.php: ...
I have a model that has two fields, which I will call first_name and last_name, and I want to make sure that the combination of the two are case-insensitively unique. I've gotten halfway there by using this: validates_uniqueness_of :first_name, :scope => :last_name The problem is that the uniqueness check seems to be case sensitive, e...

How can you use circular #import to strongly typed objects in objective-c I have an audio controller class, a menu class and a gameview class. The application delegate sets up these classes and assigns a pointers so: the menu class is aware of the audio and gameview class the gameview class has a reference to the audio and menu class ...

In Perl, does using 'my' within a foreach loop have any effect? It seems that the index variable is always local whether or not 'my' is used. So can you drop the 'my' within the foreach loop and still have private scope within the body of the loop? As can be seen, using the 'for' loop there is a difference between using / not using 'm...
I want to recreate the scope bar of a UISearchBar, just for use as tabs. I'd like to adopt the UISearchBar scope bar's style. I've thought about Quartz 2D to draw these tabs in combination with UIControl for managing the different states of the tabs. What are you thinking of? ...
