Expanding the parameter pack of indices in a comma expression with a value creates a copy of the value for each of the indices. Sadly, gcc and clang think the index has no effect and warn about it (gcc can be silenced by casting the index to void): #include <algorithm> #include <array>...

CSS variables cascade in much the same way as other properties, and can be restated safely. You can define variables multiple times and only the definition with the highest specificity will apply to the element selected. Assuming this HTML: <a class="button">Button Green</a>...

Lets have a look at the native app lifecycle methods for different platforms. Android. //Xamarin.Forms.Platform.Android.FormsApplicationActivity lifecycle methods: protected override void OnCreate(Bundle savedInstanceState); protected override void OnDestroy(); protected override void OnPause()...

Here is a simple proof by induction. Require Import Coq.Setoids.Setoid. Require Import Coq.Arith.Lt. (* A number is less than or equal to itself *) Theorem aLTEa : forall a, a <= a. auto with arith. (* This follows by simple arithmetic *) Qed. Theorem simplALTE : forall a ...

In Coq, destruct more or less corresponds to a case analysis. It is similar to induction except that there's no induction hypothesis. Here is a (admittedly rather trivial) example of this tactic: Require Import Coq.Arith.Lt. Theorem atLeastZero : forall a, 0 <= a. Proof. intros. destr...

Flask's built-in webserver is able to serve static assets, and this works fine for development. However, for production deployments that are using something like uWSGI or Gunicorn to serve the Flask application, the task of serving static files is one that is typically offloaded to the frontend webs...

So the main goal of this function is to : Be standalone because it needs to be written in the main VbScript file and cannot be in an included file (because it defines the include function) Provide enough information if something goes wrong (ie. the file that was being included, the error that oc...

To include a file in another file, just use the one liner : IncludeFile "myOtherFile.vbs"
