deprecation-warning

I've just upgraded to PHP 7 and have been hammering out errors associated with deprecated functions, with much success. Sadly, I've been having trouble fixing the new preg replace methodology for my "view php array in a interactive collapsable javascript thing" code. The following code: function print_r_tree($data) { // capture the output of $this->print_r_tree $out = print_r($data, true); // replace something like '[element] => <newline> (' with <a href="javascript:toggleDisplay('...');">...</a><div id="..." style="display: none;"> $out = preg_replace('/([ \t]*)(\[[^\]]+\][ \t]*\=\>[ \t]*[a

My code: val exitStatus = url #> outfile ! scala.sys.process : new URL("http://www.scala-lang.org/") #> new File("scala-lang.html") ! Warning: postfix operator ! should be enabled [warn] by making the implicit value scala.language.postfixOps visible. [warn] This can be achieved by adding the import clause 'import scala.language.postfixOps' [warn] or by setting the compiler option -language:postfixOps. [warn] See the Scaladoc for value scala.language.postfixOps for a discussion [warn] why the feature should be explicitly enabled. [warn] val exitStatus = url #> outfile ! [warn] ^ [warn] one

I had this legacy code in my project: Model.find(id, :readonly => false) Apparently, it searched by id and only the objects that were not readonly. But readonly is not an attribute of the Model, this should be checking the actual ActiveRecord property that defines whether that instance is a read only instance or not. I don't know if that is what this code actually does, maybe that :readonly => false is useless there. But I get the expected warning: DEPRECATION WARNING: Passing options to #find is deprecated. Please build a scope and then call #find on it. And I can't replace it with a where,

I use a version switch to support older Android versions. int sdk = Build.VERSION.SDK_INT; if (sdk < Build.VERSION_CODES.HONEYCOMB) { ColorDrawable colorDrawable = new ColorDrawable(shapeColor); //noinspection deprecation viewHolder.shape.setBackgroundDrawable(colorDrawable); } else { viewHolder.shape.setColor(shapeColor); } When build the project with Gradle from the command line the following warning is output by Lint: app/src/main/java/com/example/MyApp/CustomListAdapter.java:92: warning: [deprecation] setBackgroundDrawable(Drawable) in View has been deprecated viewHolder.shape

I have this code: DispatchQueue.global(priority: DispatchQueue.GlobalQueuePriority.default).async { let url = URL(string: itemImageURL ) let data = try? Data(contentsOf: url!) if data != nil { DispatchQueue.main.async{ cell.advImage!.image = UIImage(data: data!) } } } I get this warning in Swift 3: 'default' was deprecated in iOS 8.0: Use qos attributes instead on the first line. Haven't found yet a solution. Has anybody? try qos: DispatchQoS.QoSClass.default instead of priority: DispatchQueue.GlobalQueuePriority.default DispatchQueue.global(qos: DispatchQoS.QoSClass.default).async { let url =
