around this issue How can i use a more than 1 function inline from object? I have simple class: , You return $this so you can then continue work on the object:
code :
class test
    private $string;

    function text($text)
        $this->string = $text;
        return $this;

    function add($text)
        $this->string .= ' ' . $text;
        return $this;

it helps some times EDIT
While looking for something completely unrelated in TagList's help I've just found these two functions:

should help you out Example seem good. Just writing too many lines in each case don't seems to be good practise. Instead of that you can make function and use them. So if you want you can reuse same code other place in project. as well.
Facade pattern says that what logic your class do in itself should not be aware to other classes in project. So as per my suggestion your code should be like code below:
code :
    //: Playground - noun: a place where people can play

import UIKit

var str = "Hello, playground"

 draw a line or a circle on an image canvas

/* different printing function types */
enum FuncTypes: String {
    case Line
    case Circle
    case PrintBaseHeight
    case Default

final class ImageUtils{

    class func drawLineOnImage(funcType: FuncTypes) -> UIImage{

        //def vars
        let drawHeight = 200
        let drawWidth  = 200
//        var rectangle =  CGRect(x: 0, y: 0, width: 0, height: 0)
        UIGraphicsBeginImageContextWithOptions(CGSize(width: drawWidth, height: drawHeight), false, 0)
        var context = UIGraphicsGetCurrentContext()

        CGContextTranslateCTM(context, 0, CGFloat(drawHeight));
        CGContextScaleCTM(context, 1.0, -1.0);

        //get height and color for line
//        let LineHeight = Int(arc4random_uniform(200) )
        let LineColor = UIColor.cyanColor()
//        var heightPercent = 0

        //context stuff
        CGContextSetLineWidth(context, 1)

        //switch some func cases for image height
        switch funcType {

        case .Line:
            drawLine(&context!, height: drawHeight, LineColor: LineColor)

        case .Circle:
            print("image printingmarker")
            drawCircle(&context!, height: drawHeight, LineColor: LineColor)


        let img = UIGraphicsGetImageFromCurrentImageContext()

        return img

    static func drawLine (inout context:CGContext, height:Int, LineColor : UIColor) {

        CGContextAddArc(context, 2.5, CGFloat(height/2), 2.5, 0, CGFloat(M_PI * 2), 0)
        CGContextDrawPath(context, .FillStroke)

    static func drawCircle (inout context:CGContext, height:Int, LineColor : UIColor) {

        let LineHeight = Int(arc4random_uniform(200) )
        var heightPercent = 0

        CGContextMoveToPoint(context,0, 0)
        heightPercent = LineHeight*55/100
        CGContextSetStrokeColorWithColor(context, UIColor.whiteColor().CGColor)
        let rectangle = CGRect(x: 0, y: height/2, width: 4, height: Int(heightPercent))
        CGContextAddRect(context, rectangle)
        CGContextFillRect(context, rectangle)



let lineOnImage = ImageUtils.drawLineOnImage(FuncTypes.Line)
let circleOnImahe = ImageUtils.drawLineOnImage(FuncTypes.Circle)

like below fixes the issue
Are there language features that are easier to use with the first or second version?
code :
template<typename T>
struct MyType {
    template<typename... Args>
    void test(Args...) const;

    // Some other functions...

template<typename T>
template<typename... Args>
void MyType<T>::test(Args... args) const {
    // do things

// Out-of-line definition for all the other functions...

template<typename... Args>
void MyType<int>::test(Args... args) const {
    // do slightly different things in test
    // and in test only for MyType<int>
struct MyType<int> {
    template<typename... Args>
    void test(Args...) const {
        // Specialized function

    // Copy-and-paste of all the other functions...
struct S {
    void f();

void S::f<int>() {}

int main() {
    S s;
Function works from command line but not within class

fixed the issue. Will look into that further The console statement is executed before the promise from getBlogHeightPromise is finished.
Use await to wait for the asynchronous method getBlogHeightPromise to resolve:
code :
    // Add new block
    async addBlock(newBlock) {
        var bla = await this.getBlockHeightPromise();
        console.log('bla: ' + bla);
Why can't a class and function be defined on the same line?

hope this fix your issue For a one-line compound statement, the body must be a simple statement, or a semicolon-separated list of simple statements:
code :
suite         ::=  stmt_list NEWLINE | NEWLINE INDENT statement+ DEDENT
statement     ::=  stmt_list NEWLINE | compound_stmt
stmt_list     ::=  simple_stmt (";" simple_stmt)* [";"]
if True: if False: pass
else: print('Which "if" does this "else" go with?')
