Edit your package.json to add the following script : { "scripts": { "lint": "eslint .;exit 0" } } Then run it using npm run lint We use exit 0 as a trick to gracefully terminate the script when linting fails, otherwise npm will use eslint return code an...

This will create a timer to call the doSomething method on self in 5.0 seconds. [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(doSomething) userInfo:nil repeats:NO]; Setting the repeats parameter to false/NO indicates that we...

[timer invalidate]; timer = nil; This will stop the timer from firing. Must be called from the thread the timer was created in, see Apple's notes: You must send this message from the thread on which the timer was installed. If you send this message from another thread, the input source associ...

[timer fire]; Calling the fire method causes an NSTimer to perform the task it would have usually performed on a schedule. In a non-repeating timer, this will automatically invalidate the timer. That is, calling fire before the time interval is up will result in only one invocation. In a repeat...

This sample annotation indicates that the following method is deprecated. @deprecated def anUnusedLegacyMethod(someArg: Any) = { ... } This can also be equivalently written as: @deprecated def anUnusedLegacyMethod(someArg: Any) = { ... }

survival is the most commonly used package for survival analysis in R. Using the built-in lung dataset we can get started with Survival Analysis by fitting a regression model with the survreg() function, creating a curve with survfit(), and plotting predicted survival curves by calling the predict m...

zf{motion} creates a fold that covers the text that "motion" would cover. {count}zF creates a fold that covers "count" lines. {range}fo[ld] creates a fold for the lines in the provided range. All three commands are valid only when foldmethod is set to manual or marker. In ...

zo opens a fold underneath the cursor. zO opens all folds underneath the cursor, recursively. zc closes a fold underneath the cursor. zC closes all folds underneath the cursor, recursively. za toggles a fold under the cursor (a closed fold is opened, an opened fold is closed). zM closes all f...

var go = GameObject.Find("NameOfTheObject"); ProsConsEasy to usePerformance degrades along the number of gameobjects in sceneStrings are weak references and suspect to user errors

var go = GameObject.FindGameObjectWithTag("Player"); ProsConsPossible to search both single objects and entire groupsStrings are weak references and suspect to user errors.Relatively fast and efficientCode is not portable as tags are hard coded in scripts.

AlertDialog is a subclass of Dialog that can display one, two or three buttons. If you only want to display a String in this dialog box, use the setMessage() method. The AlertDialog from android.app package displays differently on different Android OS Versions. The Android V7 Appcompat library pro...

One of the most powerful capabilities in Excel is the use of Pivot Tables to sort and analyze data. Using VBA to create and manipulate the Pivots is easier if you understand the relationship of Pivot Tables to Pivot Caches and how to reference and use the different parts of the Tables. At its most ...

You are right in the middle of working on a new feature, and your boss comes in demanding that you fix something immediately. You may typically want use git stash to store your changes away temporarily. However, at this point your working tree is in a state of disarray (with new, moved, and removed ...

> List.repeat 3 "abc" ["abc","abc","abc"] : List String You can give List.repeat any value: > List.repeat 2 {a = 1, b = (2,True)} [{a = 1, b = (2,True)}, {a = 1, b = (2,True)}] : List {a : Int, b : (Int, Bool)}

By default, List.sort sorts in ascending order. > List.sort [3,1,5] [1,3,5] : List number List.sort needs the list elements to be comparable. That means: String, Char, number (Int and Float), List of comparable or tuple of comparable. > List.sort [(5,"ddd"),(4,"zzz"),...

List.sortWith allows you to sort lists with data of any shape - you supply it with a comparison function. compareBools : Bool -> Bool -> Order compareBools a b = case (a,b) of (False, True) -> LT (True, False) -> GT _ -> ...

Note: this is not very efficient due to the nature of List (see Remarks below). It will be better to construct the list the "right" way from the beginning than to construct it and then reverse it. > List.reverse [1,3,5,7,9] [9,7,5,3,1] : List number

By default List.sort sorts in ascending order, with the compare function. There are two ways to sort in descending order: one efficient and one inefficient. The efficient way: List.sortWith and a descending comparison function. descending a b = case compare a b of LT -> GT ...

List.sortBy allows to use a function on the elements and use its result for the comparison. > List.sortBy String.length ["longest","short","medium"] ["short","medium","longest"] : List String -- because the lengths are: [7,5,6] It ...
