Building OS X Apps with JavaScript


OS X Yosemite introduced JavaScript for Automation. This makes it possible to access native OS X frameworks with JavaScript.

The result above can be built using this code:


var styleMask = $.NSTitledWindowMask | $.NSClosableWindowMask | $.NSMiniaturizableWindowMask;
var windowHeight = 85;
var windowWidth = 600;
var ctrlsHeight = 80;
var minWidth = 400;
var minHeight = 340;
var window = $.NSWindow.alloc.initWithContentRectStyleMaskBackingDefer(
  $.NSMakeRect(0, 0, windowWidth, windowHeight),

var textFieldLabel = $.NSTextField.alloc.initWithFrame($.NSMakeRect(25, (windowHeight - 40), 200, 24));
textFieldLabel.stringValue = "Image: (jpg, png, or gif)";
textFieldLabel.drawsBackground = false;
textFieldLabel.editable = false;
textFieldLabel.bezeled = false;
textFieldLabel.selectable = true;

var textField = $.NSTextField.alloc.initWithFrame($.NSMakeRect(25, (windowHeight - 60), 205, 24));
textField.editable = false;

var btn = $.NSButton.alloc.initWithFrame($.NSMakeRect(230, (windowHeight - 62), 150, 25));
btn.title = "Choose an Image...";
btn.bezelStyle = $.NSRoundedBezelStyle;
btn.buttonType = $.NSMomentaryLightButton;

window.title = "Choose and Display Image";

By the looks of if you’re writing Cocoa, in a JavaScript syntax. Reminds me of the fact that you can record Photoshop actions in either VBScript or JavaScript code … and even translate those to C#.
