Passing optional callback into Swift function
Update for Swift 3/4: An optional is no longer a boolean expression, and the deprecated func dismissModalViewControllerAnimated(animated: Bool) is no longer available in Swift. Simply declare the completion parameter as an optional closure, and pass it on to func dismiss(animated flag: Bool, completion: (() -> Void)? = nil) which takes an optional closure as well: … Read more
Function to remove accents in postgreSQL [duplicate]

Good explanation of “Combinators” (For non mathematicians)
Unless you’re deeply into theory, you can regard the Y combinator as a neat trick with functions, like monads. Monads allow you to chain actions, the Y combinator allows you to define self-recursive functions. Python has built-in support for self-recursive functions, so you can define them without Y: > def fun(): > print “bla” > … Read more
What does :: (double colon) stand for?
You can google for haskell “double colon” or similar things; it’s unfortunately a bit hard to google for syntax, but in this case you can name it. In Haskell, your programs will often run fine without it (though you will want to use it to hone the specification of any functions you define, and it … Read more
Function naming conventions [closed]
One of the more universal, yet simple rules is: Function names should be verbs if the function changes the state of the program, and nouns if they’re used to return a certain value.
How to pass variable length arguments as arguments on another function in Golang?
Ah found it…functions that accept variable length arguments are called Variadic Functions. Example: package main import “fmt” func MyPrint(format string, args …interface{}) { fmt.Printf(“[MY PREFIX] ” + format, args…) } func main() { MyPrint(“yay %d %d\n”,123,234); MyPrint(“yay %d\n “,123); MyPrint(“yay %d\n”); }
Call a function in another script when executing using ‘Run With PowerShell’
In the worker file change to this: . “c:\scratch\b.ps1” ShowMessage “Hello” As @RoiDanton mentioned below: Attention when using relative pathing: Don’t forget to prepend a dot before the path . “.\b.ps1”. The first dot is an operator used to modify the scope and in that context it has nothing to do with paths. See Dot … Read more
