&gt;Xcode 4 has a new set of command for moving the line where the cursor is or the selected text with `command` + `option` + `[` or `]` 
&gt;
&gt;`⌥⌘[` or `⌥⌘]`

**If you are using a Windows keyboard, the commands would translate to:**

 - `⌥⌘[` ..... `Alt + Win + [`
 - `⌥⌘]` ..... `Alt + Win + ]`

I&#39;m looking for a feature comparable to Python interactive shell&#39;s &quot;_&quot; variable. In PowerShell I want something like this:


    &gt; Get-Something # this returns an object and display it to the output.
    # Now I want to assign that object to some variable
    &gt; $anObj = ???

I&#39;m currently testing my InApp billing mechanism (using the InApp Billing version 3 API, therefore taking the TrivialDrive example as reference).

I have one managed item, which is upgrade to premium version.

Now, purchasing the item with my test account works, but when I do a cancellation of the entire order in Google checkout afterwards, my code still tells me that the item is purchased an therefore grants the premium features.

Here is how I check for the purchase in my MainActivity. I do not save the purchase state locally somewhere, as I understood that the with the billing API v3, you can query for purchases ad hoc as needed.

    @Override
    	protected void onStart() {
    		// TODO Auto-generated method stub
    		super.onStart();
    		
    		iabHelper = new IabHelper(this, Helper.getPKey());
            iabHelper.enableDebugLogging(true);
            
            iabHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
    			
    			@Override
    			public void onIabSetupFinished(IabResult result) {
    				Log.d(&quot;IAB&quot;, &quot;SETUP FINISHED&quot;);
    				
    				if(!result.isSuccess())
    				{
    					Log.d(&quot;IAB&quot;, &quot;SETUP NOT OK&quot;);
    					return;
    				}
    				else
    					Log.d(&quot;IAB&quot;, &quot;SETUP OK&quot;);
    					
    				iabHelper.queryInventoryAsync(
    					new QueryInventoryFinishedListener() {
    						
    						@Override
    						public void onQueryInventoryFinished(IabResult result, Inventory inv) {
    							Log.d(&quot;IAB&quot;, &quot;Query inventory finished.&quot;);
    				            if (result.isFailure()) {
    				                Log.d(&quot;IAB&quot;,&quot;Failed to query inventory: &quot; + result);
    				                return;
    				            }
    
    				            Log.d(&quot;IAB&quot;, &quot;Query inventory was successful.&quot;);
    
    				            // Do we have the premium upgrade?
    				            boolean mIsPremium = inv.hasPurchase(Helper.premiumSku);
    				            Purchase p = inv.getPurchase(Helper.premiumSku);
    				            if(p != null)
    				            	Log.d(&quot;IAB PURCHASE STATE&quot;, IabHelper.getResponseDesc(p.getPurchaseState()));
    				            else
    				            	Log.d(&quot;IAB PURCHASE STATE&quot;, &quot;Purchase is null&quot;);
    				            
    				            Log.d(&quot;IAB&quot;, &quot;User is &quot; + (mIsPremium ? &quot;PREMIUM&quot; : &quot;NOT PREMIUM&quot;));
    				            
    							
    						}
    					}						
    					
    				);				
    			}
    		});       
    	}

I keep getting getPurchaseState = 0, which means is Purchased, even one hour after I cancelled the order. Why?

In Xcode 4, I have been sucessfully able to add new custom keyboard shortcuts to move lines around or to duplicate a line:

**/Applications/Xcode.app/Contents/Frameworks/IDEKit.framework/Resources/IDETextKeyBindingSet.plist**

    &lt;key&gt;My Custom Keys&lt;/key&gt;
    &lt;dict&gt;
        &lt;key&gt;Move Line Up&lt;/key&gt;
        &lt;string&gt;selectLine:, cut:, moveUp:, moveToBeginningOfLine:, paste:, moveUp:&lt;/string&gt;
        &lt;key&gt;Move Line Down&lt;/key&gt;
        &lt;string&gt;selectLine:, cut:, moveDown:, moveToBeginningOfLine:, paste:, moveUp:&lt;/string&gt;

        &lt;string&gt;moveToBeginningOfLine:, deleteToEndOfLine:, yank:, insertNewline:, moveToBeginningOfLine:, yank:&lt;/string&gt;
        &lt;key&gt;Delete Line&lt;/key&gt;
        &lt;string&gt;selectLine:, delete:&lt;/string&gt;
    &lt;/dict&gt;

But the **Move Line Up/Down** uses copy/paste, which I would like to avoid. Anyone knows how to move lines with *yank*, just like the **Duplicate Line** I found there: https://stackoverflow.com/questions/10266170/xcode-4-duplicate-line/13369654#13369654

I have a curios issue. 

I have a project that I&#39;ve worked on and always built from the XCode IDE, and it worked fine. Now I&#39;m setting up Bamboo to build the project and as such am building it from the command line.

The issue is, if I check my code out of GIT and then use xcodebuild to build it it says that the scheme cannot be found, but if I open the project, it builds and if I then try to build it again from the command line with the same command, it works.

What magic is XCode doing when I open the project or am I doing something dumb, maybe excluding a file in my .gitignore that I shouldn&#39;t?

I have an All Exceptions breakpoint configured in Xcode:

![screenshot of an exception breakpoint configured in Xcode breakpoint pain, configured to make a sound when an exception is thrown][1]

Sometimes Xcode will stop on a line like:

&lt;!-- lang: objective-c --&gt;

    [managedObjectContext save:&amp;error];

with the following backtrace:

![backtrace showing NSPersistentStoreCoordinator throwing an exception inside the call to save:][2]

but the program continues on as if nothing happened if you click Continue.

__How can I ignore these &quot;normal&quot; exceptions, but still have the debugger stop on exceptions in my own code?__

(I understand that this happens because Core Data internally throws and catches exceptions, and that Xcode is simply honoring my request to pause the program whenever an exception is thrown. However, I want to ignore these so I can get back to debugging my own code!)

*Moderators: this is similar to [&quot;Xcode 4 exception breakpoint filtering&quot;][3], but I think that question takes too long to get around to the point and doesn&#39;t have any useful answers. Can they be linked?*

At some point in my app I have a highlighted `UIButton` (for example when a user has his finger on the button) and I need to change the background color while the button is highlighted (so while the finger of the user is still on the button).

I tried the following:

    _button.backgroundColor = [UIColor redColor];

But it is not working. The color remains the same. I tried the same piece of code when the button is not highlighted and it works fine. I also tried calling `-setNeedsDisplay` after changing the color, it didn&#39;t have any effect.

Using Xcode 4.5.1. Our project has been building fine for the last three months, but suddenly, when I try to build, it says &quot;Build failed&quot;, but does not show any errors on the triangle exclamation mark tab, nor does it give a reason when it pops up build failed.

We have not changed the bundle identifier, or any other project properties. I tried a clean, then build, but no luck.

What may be causing the problem?

Xcode: Build Failed, but no error messages

I&#39;m having trouble running my basic iPhone application (while going through the Stanford iTunes CS193p lectures) in the iOS simulator.

I&#39;ve been searching for a while (both Google and SO), but unable to find a solution so far. There are many similar bugs, but the solutions don&#39;t seem to fix this.

In Xcode I click &quot;run&quot;. It compiles and builds successfully, launches iOS simulator but it never gets to loading the app. Only the status bar at the top.  With a black screen.

I&#39;ve only written very basic code (following along with the lectures) and can&#39;t get past this problem.  

To confuse matters more, I wrote a web wrapper `(UIWebView)` before these lectures and this works fine. But there is barely any difference in the code.  All new apps I create from scratch all fail with the same black screen problem. 

If I hit the home button on the simulator and launch the app, it will display. But Xcode doesn&#39;t seem to know what&#39;s going on.

It&#39;s as if Xcode has lost the ability to talk to iOS Simulator and assumes it&#39;s running (even if I quit iOS simulator). I try and quit Xcode, and it asks me to stop the tasks. Then it just hangs.  So I have to force restart to get out of Xcode.

When using *Sublime Text 2* we tend to open the *side bar* to navigate thru files/folders in our projects. For that we can use the hotkey *ctrl+k ctrl+b* (in windows).

However, once we&#39;re in the *side bar*, we **can&#39;t use it with keyboard** (arrows for instance). We have to stick using it with our own mouse...

**Just a note**: I installed SideBarEnhancements plugin, but I didn&#39;t find anything that could solve my problem.

https://stackoverflow.com/questions/5885739/why-are-some-textboxes-not-accepting-control-a-shortcut-to-select-all-by-defau

But that answer doesn&#39;t work for me. I have this code:

    public class LoginForm : Form
    {
        private TextBox tbUsername;
        
        public LoginForm()
        {
            tbUsername = new TextBox();
            tbUsername.ShortcutsEnabled = true;
            tbUsername.Multiline = false;
            Controls.Add(tbUsername);
        }
    }

The textbox shows up, I can write on it, I can cut, copy and paste text on it without any problems.
But when I try to press &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;A&lt;/kbd&gt; I only hear a &quot;bling&quot; similar to the bling that you hear if you try to erase text from an empty textbox (try it with your browser&#39;s address bar).

I want to create an Eclipse style shortcut &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;MouseClick&lt;/kbd&gt; to open the function/method. Sublime Text 3 has already this function called `goto_definition` but it is bound to &lt;kbd&gt;F12&lt;/kbd&gt;. 

![][1]

But I&#39;m not sure how to create this binding. I looked [here][2] for documentation but it was too complex. Can you one help me out with this simple key binding?

**Edit:** Following this article I was told to do this: [http://webtempest.com/better-definition-navigation-in-sublime-text-3/][3]

    [
        {
            &quot;button&quot;: &quot;button1&quot;,

            &quot;command&quot;: &quot;goto_definition&quot;
        }
    ]

This doesn&#39;t seem to work, &lt;kbd&gt;ctrl&lt;/kbd&gt;+&lt;kbd&gt;shift&lt;/kbd&gt;+&lt;kbd&gt;click&lt;/kbd&gt; executes nothing.

How to select all instances of a variable and edit variable name in Sublime

I am a Python beginning self-learner, running on MacOS.

I&#39;m making a program with a text parser GUI in tkinter, where you type a command in a `Entry` widget, and hit a `Button` widget, which triggers my `parse()` funct, ect, printing the results to a `Text` widget, text-adventure style.

&gt; \&gt; Circumvent the button
&gt;
&gt; I can&#39;t let you do that, Dave.

I&#39;m trying to find a way to get rid of the need to haul the mouse over to the `Button` every time the user issues a command, but this turned out harder than I thought.

I&#39;m guessing the correct code looks like `self.bind(&#39;&lt;Return&gt;&#39;, self.parse())`? But I don&#39;t even know where to put it. `root`, `__init__`, `parse()`, and `create_widgets()` don&#39;t want it.

To be clear, the only reason anyone should hit enter in the prog is to trigger `parse()`, so it doesn&#39;t need to be espoused to the `Entry` widget specifically. Anywhere it works is fine.

In response to 7stud, the basic format:

    from tkinter import *
    import tkinter.font, random, re
    
    class Application(Frame):
        
        def __init__(self, master):
            Frame.__init__(self, master, ...)
            self.grid()
            self.create_widgets()
            self.start()
    
            
        def parse(self):
            ...
    
    
        def create_widgets(self):
            
            ...
    
            self.submit = Button(self, text= &quot;Submit Command.&quot;, command= self.parse, ...)
            self.submit.grid(...)
    
            
    root = Tk()
    root.bind(&#39;&lt;Return&gt;&#39;, self.parse)
    
    app = Application(root)
    
    root.mainloop()



How do I bind the enter key to a function in tkinter?

I understand that Mac has some Emacs keybindings enabled by default (e.g. &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;A&lt;/kbd&gt; move to beginning of line etc.). If I open TextEdit for example I can navigate like in Emacs.

But when I try &lt;kbd&gt;Alt&lt;/kbd&gt;+&lt;kbd&gt;F&lt;/kbd&gt; or &lt;kbd&gt;Alt&lt;/kbd&gt;+&lt;kbd&gt;b&lt;/kbd&gt; for move to next word or last word it does not work. It prints out `ƒ` and `∫` instead.

Is there a way to jump words instead?

I think that I did not tinker with the keybindings and I use the US layout on a german keyboard.

Is there a way to make alt-f and alt-b jump word forward and backward instead of printing ƒ and ∫ on Mac?

I&#39;m looking for a way to bind a function to my whole page (when a user presses a key, I want it to trigger a function in my component.ts)

It was easy in AngularJS with a `ng-keypress` but it does not work with `(keypress)=&quot;handleInput($event)&quot;`. 

I tried it with a div wrapper on the whole page but it doesn&#39;t seem to work.
it only works when the focus is on it.

&lt;!-- language: lang-xml --&gt;

    &lt;div (keypress)=&quot;handleInput($event)&quot; tabindex=&quot;1&quot;&gt;
