We faced a similar issue and emailed Disqus about this. They confirmed that by default they only support one Disqus module per page. When browsing the Disqus JS documentation, I did find a solution that might work for you by loading and unloading the Disqus modules as the user interacts with the site: DISQUS.reset({ reload: … Read more
Yes, sure. Normal name lookup rules apply. [expr.prim.lambda]/7 … for purposes of name lookup … the compound-statement is considered in the context of the lambda-expression. Re: why local variables are treated differently from global ones. [expr.prim.lambda]/13 … If a lambda-expression or an instantiation of the function call operator template of a generic lambda odr-uses (3.2) … Read more
The compiler is not allowed to optimiza away global objects. Even if they are never used. Somthing else is happening in your code. Now if you built a static library with your global object and that global object is not referenced from the executable it will not be pulled into the executable by the linker.
You have just stumbled on a js “feature” called hoisting var myname = “global”; // global variable function func() { alert(myname); // “undefined” var myname = “local”; alert(myname); // “local” } func(); In this code when you define func the compiler looks at the function body. It sees that you are declaring a variable called … Read more
The differences are: The name is only accessible within the function, and has no linkage. It is initialised the first time execution reaches the definition, not necessarily during the program’s initialisation phases. The second difference can be useful to avoid the static intialisation order fiasco, where global variables can be accessed before they’re initialised. By … Read more
If your file-scope variable is not static, then you can use a declaration that uses extern in a nested scope: int c; int main() { { int c = 0; // now, c shadows ::c. just re-declare ::c in a // nested scope: { extern int c; c = 1; } // outputs 0 printf(“%d\n”, … Read more
Update 2021 October Applies to TypeScript 4.3+ Error Element implicitly has an any type because type typeof globalThis has no index signature. ts(7017) Solution declare global { function myFunction(): boolean; var myVariable: number; } globalThis.myFunction = () => true; globalThis.myVariable = 42; IMPORTANT: This solution only works by declaring variables with var (do not use … Read more
Excuse me when I answer your questions out-of-order, it makes it easier to understand this way. When static variable is declared in a header file is its scope limited to .h file or across all units. There is no such thing as a “header file scope”. The header file gets included into source files. The … Read more
Static limits the scope of the variable to the same translation unit. A static global variable has internal linkage. A non-static global variable has external linkage. Good Read: What is external linkage and internal linkage?
var should definitely not be shared as long as you access it by instance.var or self.var. With the list however, what your statement does is when the class gets evaluated, one list instance is created and bound to the class dict, hence all instances will have the same list. Whenever you set instance.list = somethingelse … Read more
