Could that be done with class variables? -- Ticket URL: <http://www.macruby.org/trac/ticket/477> MacRuby <http://macruby.org/>

[MacRuby] #562: Including a module into class Class or class Module

#562: Including a module into class Class or class Module -------------------------------------+-------------------------------------- Reporter: eloy.de.enige@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: mocha -------------------------------------+-------------------------------------- I saw that when you open class Class and define a method, it's automatically defined as a class method on NSObject. My preliminary patch does this for both Class and Module. However, as the test in #3300 shows, using the two behaviors together still leads to a problem. -- Ticket URL: <http://www.macruby.org/trac/ticket/562> MacRuby <http://macruby.org/>

Is there a reason for them to be different, or is that just historical baggage? -- Ticket URL: <http://www.macruby.org/trac/ticket/630> MacRuby <http://macruby.org/>

[MacRuby] #623: Overriding setRepresentedObject on NSViewController subclass doesn't seem to work

#623: Overriding setRepresentedObject on NSViewController subclass doesn't seem to work -----------------------------+---------------------------------------------- Reporter: ninh@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: MacRuby 0.6 Component: MacRuby | Keywords: -----------------------------+---------------------------------------------- Overriding setRepresentedObject in a subclass of NSViewController seems to have no effect. In particular, in macrubybind.rb, it shows that a custom setMyRepresentedObject is being used, but when you just override setRepresentedObject, it's not being used in conjunction with cocoa bindings. In NinhBindingTest.zip (kindly provided by Johannes Fahrenkrug) you can see that in objective C it works as expected though, i.e. overriding setRepresentedObject yields the expected behavior. -- Ticket URL: <http://www.macruby.org/trac/ticket/623> MacRuby <http://macruby.org/>

#594: Not all methods visible to objective-c calls ------------------------------+--------------------------------------------- Reporter: michael@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: ------------------------------+--------------------------------------------- The following code is taken from http://code.reflectivepixel.com/post/103638573/require-hotcocoa-framework- webkit-class and is just a short example of showing the problem: {{{ require 'hotcocoa' framework 'webkit' class Application include HotCocoa FULL={:expand => [:width,:height]} BASE=<<-END <html><head><style type="text/css"> * { font-family: Monaco; } </style><script type="text/javascript"> function say(arg) { window.TheBridge.click(arg);} </script> </head><body><h3>Ruby JavaScript Bridge</h3> <a href="#" onclick="say('hi')">tell</a></body></html> END def click(arg) #called from javascript root = document.createElement("div"); root.innerHTML="javascript tells ruby: #{arg}" document.body.appendChild(root) end def document @web_view.mainFrame.DOMDocument end def self.webScriptNameForSelector(sel) #hide : in name sel.to_s.sub(/:$/,'') if is_available_selector?(sel) end def self.isSelectorExcludedFromWebScript(sel) ! is_available_selector?(sel) end def self.isKeyExcludedFromWebScript(key) true end def self.is_available_selector?(sel) ['click:'].include?(sel.to_s) end def start application :name => "MyBridge" do |app| app.delegate = self window :title => "MyBridge", :frame => [10, 620, 330, 230] do |win| win << @web_view=web_view(:layout => FULL) do |wv| wv.mainFrame.loadHTMLString BASE, baseURL: nil wv.frameLoadDelegate=self wso=wv.windowScriptObject #make visible to JS wso.setValue(self, forKey:"TheBridge") end win.will_close { exit } end end end end Application.new.start }}} In this example, clicking on "tell" does not work. It seems, that the selector for "click:" is not found. When logging for example the selector values in {{{ self.isSelectorExcludedFromWebScript(sel) }}}, the "click:" selector is not amongst the results. This is not related to hotcocoa, this example can be simply reworked without using hotcocoa, just with a simple WebView embedded in a NSWindow from Interface Builder. -- Ticket URL: <http://www.macruby.org/trac/ticket/594> MacRuby <http://macruby.org/>
