take a look at this sample playbook: — – hosts: localhost vars: iter: – key: abc val: xyz – key: efg val: uvw tasks: – set_fact: {“{{ item.key }}”:”{{ item.val }}”} with_items: “{{iter}}” – debug: msg=”key={{item.key}}, hostvar={{hostvars[‘localhost’][item.key]}}” with_items: “{{iter}}”
Great question. Two facts that you probably don’t know: Dynamic behind the scenes is just object. That is, a “dynamic” variable is an “object” variable with a hint to the compiler that says “generate dynamic operations on this variable when it is used.” There is no such thing as a boxed nullable. When you box … Read more
The JFreeChart class DynamicTimeSeriesCollection is a good choice. Addendum: As noted by @Bahadır, the last point of the series was persistently zero. @Don helpfully suggests advancing the time and then appending the data. dataset.advanceTime(); dataset.appendData(newData); import java.awt.BorderLayout; import java.awt.EventQueue; import java.awt.FlowLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.util.Random; import javax.swing.JButton; import javax.swing.JComboBox; import javax.swing.JPanel; import javax.swing.Timer; … Read more
This answer assumes that you know basic Linux command. In Linux, there are two types of libraries: static or shared. In order to call functions in a static library you need to statically link the library into your executable, resulting in a static binary. While to call functions in a shared library, you have two … Read more

The following structure should work for you: <button mat-button [matMenuTriggerFor]=”main_menu”>My menu</button> <mat-menu #main_menu=”matMenu”> <ng-container *ngFor=”let mainItem of objectKeys(my_menu)”> <button mat-menu-item [matMenuTriggerFor]=”sub_menu”>{{ mainItem }}</button> <mat-menu #sub_menu=”matMenu”> <button *ngFor=”let subItem of my_menu[mainItem]” mat-menu-item>{{ subItem }}</button> </mat-menu> </ng-container> </mat-menu> Since I placed sub_menu inside the embedded template (*ngFor) we can use the same name for template reference variable(#sub_menu). … Read more
I think it would be more useful to build Spannable. private static final Factory spannableFactory = Spannable.Factory .getInstance(); private static final Map<Pattern, Integer> emoticons = new HashMap<Pattern, Integer>(); static { addPattern(emoticons, “:)”, R.drawable.emo_im_happy); addPattern(emoticons, “:-)”, R.drawable.emo_im_happy); // … } private static void addPattern(Map<Pattern, Integer> map, String smile, int resource) { map.put(Pattern.compile(Pattern.quote(smile)), resource); } public static … Read more
You can make an image with the canvas element, and then just replace the current favicon. Check out the following link for a good explanation on it. Reference Code is from the above reference. Markup <link id=”favicon” rel=”icon” type=”image/png” href=”image.png” /> JS (function () { var canvas = document.createElement(‘canvas’), ctx, img = document.createElement(‘img’), link = … Read more
What you need to remember is that dynamic resolution basically does the same process as static resolution, but at runtime. Anything that couldn’t be resolved by the CLR won’t be resolved by the DLR. Let’s take this small program, inspired by yours, and that doesn’t use dynamic at all: namespace ConsoleApplication38 { public interface IActualInterface … Read more
