Basic example

# app.cr

require "src/hoop"
include Hoop

NSAutoreleasePool.new
NSApp.activation_policy = LibAppKit::NSApplicationActivationPolicy::Regular
appName = "Hello, World !".to_objc

window = NSWindow.new(NSRect.new(0, 0, 700, 700).to_objc, LibAppKit::NSWindowMask::Titled, LibAppKit::NSBackingStoreType::Buffered, false)
window.set_background_color = NSColor.white_color.to_objc
window.cascade_top_left_from_point NSPoint.new(20, 20).to_objc
window.title = appName
window.make_key_and_order_front nil.to_objc

b = NSButton.new(NSRect.new(50, 50, 600, 100).to_objc)
b.set_title = "MAKE REQUEST"

class Foo < NSObject
  export_class
  def bar
	url = NSURL.url_with_string "https://jsonplaceholder.typicode.com/posts/2"
	req = NSURLRequest.request_with_url url.to_objc
	res = NSURLResponse.new

	data = NSURLConnection.send_synchronous_request req.to_objc, res.to_objc, nil.to_objc
	ns_log data

	result = NSJSONSerialization.json_object_with_data data.to_objc, LibCF::NSJSONReadingOptions::KNilOptions, nil.to_objc
	ns_log result

	userId = result.object_for_key("userId")
	id = result.object_for_key("id")
	title = result.object_for_key("title")
	body = result.object_for_key("body")

	ns_log "#{userId.as(NSNumber).intValue}"
	ns_log "#{id.as(NSNumber).intValue}"
	ns_log "#{title.as(NSString)}"
	ns_log "#{body}"

    alert = NSAlert.new
    alert.set_message_text = "User Id: #{userId.as(NSNumber).intValue} - Id: #{id.as(NSNumber).intValue} - Title: #{title} - Body: #{body}"
    alert.run_modal
  end
  export "bar"
end

b.target = Foo.new.to_objc
b.action = "bar"

window.content_view << b.to_objc

hoop's Issues

Create Documentation

Kind of a feature/enhancement kind of issue:

Make a documentation for this somewhere, like GitBook.

bundle.sh in example/bundled_application tries to copy assets folder that doesnt exist

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Could not find a storyboard named 'Main' in bundle NSBundle </Users/nick/Code/Personal/hoop/example/bundled_application/Hoop.app> (loaded)'

Test specs

example in readme doesn't work

the require line doesn't work as-is and once you eventually coax it into something that does work you get an app that just spits out

2018-06-09 20:11:53.365 crystal-run-app.tmp[15858:15753157] app launched

and nothing else. Judging by the code there's supposed to be a window and a button and the button should do something when clicked.

Doesn't run in Crystal 0.20.0

Error while trying to run an example (all examples fail):

Snippet:

p window.content_view.frame

Error:
