  • Simplest way to match array of strings to search in perl?

    - by Ben Dauphinee
    What I want to do is check an array of strings against my search string and get the corresponding key so I can store it. Is there a magical way of doing this with Perl, or am I doomed to using a loop? If so, what is the most efficient way to do this? I'm relatively new to Perl (I've only written 2 other scripts), so I don't know a lot of the magic yet, just that Perl is magic =D Reference Array: (1 = 'Canon', 2 = 'HP', 3 = 'Sony') Search String: Sony's Cyber-shot DSC-S600 End Result: 3

  • Squeeze/Lenny compilation : Library Link error

    - by PEZ
    I've got a problem here : I have a C++ Library ("DataTsBroad") and a C++ Test app ("DataTsBroadTest"), to test it. Actually, the Lib and the Test app are both compiled an a Debian Lenny. Now, i want to continue to compile my Test app on a Debian Lenny (customer constraint), but i would compile my lib on a Squeeze or a Wheezy to work on the last Debian releases. So, i successfully compiled my Lib on a Squeeze, But, after, when i try to compile my Test app with this Lib on the Lenny, it fails ! There is a Link Error : Linking CXX executable DataTsBroadTest /home/nis/pezierg/test/ProductMak/Export/DataTsBroad/L64/Release/libDataTsBroad64.so: undefined reference to `std::ctype::_M_widen_init() const@GLIBCXX_3.4.11' collect2: ld returned 1 exit status make[2]: *** [DataTsBroadTest] Error 1 make[1]: *** [CMakeFiles/DataTsBroadTest.dir/all] Error 2 make: * [all] Error 2 The problem is certainly due to ostream C++ Lib, I tried to comment all it's uses in my Lib and it works. But how can i really fix the problem ?

  • Updating Commit Message in Mercurial MQ extension

    - by Jerub
    After using hg qnew and hg qrefresh to create and update a patch that I want to apply to my repository, but the commit message that I wrote when I did hg qnew was not very good, it did not reference the ticket number from trac, and I would like to say something in it about some of the issues that my commit addresses. How do I do something like hg qrewritemycommitmessage. I have examined the docs on the website (starting here: http://mercurial.selenic.com/wiki/MqExtension ) and I have come up blank.

  • When are references declared in a switch statement?

    - by sandis
    To my surprise this code works fine: int i = 2; switch(i) { case 1: String myString = "foo"; break; case 2: myString = "poo"; System.out.println(myString); } But the String reference should never be declared? Could it be that all variables under every case always are declared no matter what, or how is this resolved?

  • Working with anonymous modules in Ruby

    - by Byron Park
    Suppose I make a module as follows: m = Module.new do class C end end Three questions: Other than a reference to m, is there a way I can access C and other things inside m? Can I give a name to the anonymous module after I've created it (just as if I'd typed "module ...")? How do I delete the anonymous module when I'm done with it, such that the constants it defines are no longer present?

  • iPhone OS: KVO: Why is my Observer only getting notified at applicationDidfinishLaunching

    - by nickthedude
    I am basically trying to implement an achievement tracking setup in my app. I have a managedObjectModel class called StatTracker to keep track of all sorts of stats and I want my Achievement tracking class to be notified when those stats change so I can check them against a value and see if the user has earned an achievement. I've tried to impliment KVO and I think I'm pretty close to making it happen but the problem I'm running into is this: So in the appDelegate i have an Ivar for my Achievement tracker class, I attach it as an observer to a property value of my statTracker core data entity in the applicationDidFinishLaunching method. I know its making the connection because I've been able to trigger a UIAlert in my AchievementTracker instance, and I've put several log statements that should be triggered whenever the value on the StatTracker's property changes. the log statement appears only once at the application launch. I'm wondering if I'm missing something in the whole object lifecycle scheme of things, I just don't understand why the observer stops getting notified of changes after the applicationDidFinishLaunching method has run. Does it have something to do with the scope of the AchievementTracker reference or more likely the reference to my core data StatTracker is going away once that method finishes up. I guess I'm not sure the right place to place these if that is the case. Would love some help. Here is the code where I add the observer in my appDidFinishLaunching method: [[CoreDataSingleton sharedCoreDataSingleton] incrementStatTrackerStat:@"timesLaunched"]; achievementsObserver = [[AchievementTracker alloc] init]; StatTracker *object = nil; object = [[[CoreDataSingleton sharedCoreDataSingleton] getStatTracker] objectAtIndex:0]; NSLog(@"%@",[object description]); [[CoreDataSingleton sharedCoreDataSingleton] addObserver:achievementsObserver toStat:@"refreshCount"]; here is the code in my core data singleton: -(void) addObserver:(id)observer toStat:(NSString *) statToObserve { NSLog(@"observer added"); NSArray *array = [[NSArray alloc] init]; array = [self getStatTracker]; [[array objectAtIndex:0] addObserver:observer forKeyPath:statToObserve options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld context:NULL]; } and my AchievementTracker: - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { NSLog(@"achievemnt hit"); //NSLog("%@", [change description]); if ([keyPath isEqual:@"refreshCount"] && ((NSInteger)[change valueForKey:@"NSKeyValueObservingOptionOld"] == 60) ) { NSLog(@"achievemnt hit inside"); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"title" message:@"achievement unlocked" delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:nil]; [alert show]; } }

  • What exactly are administrative redexes after CPS conversion?

    - by eljenso
    In the context of Scheme and CPS conversion, I'm having a little trouble deciding what administrative redexes (lambdas) exactly are: all the lambda expressions that are introduced by the CPS conversion only the lambda expressions that are introduced by the CPS conversion but you wouldn't have written if you did the conversion "by hand" or through a smarter CPS-converter If possible, a good reference would be welcome.

  • When am I supposed to use UITableViewCellSeparatorStyleSingleLineEtched?

    - by tewha
    I see a description of what UITableViewCellSeparatorStyleSingleLineEtched looks like in Apple's Class Reference, and can see it by running the application. But I can't find any mention of when it's appropriate to use UITableViewCellSeparatorStyleSingleLineEtched instead of UITableViewCellSeparatorStyleSingleLine. In other words, what does this etched line mean to the user? Can anyone explain?

  • Specify default WCF endpoint in app.config

    - by Nelson
    When you add a service reference it creates the class "MyServiceClient" with a default constructor. If I use new MyServiceClient() I get an error: Could not find default endpoint... If I use new MyServiceClient("endpointName") it works. I would like to specify a default endpoint in app/web.config which will get used when I use the default constructor. I know I can place that default name in *.settings which ends up in app.config, but just wondering if there is any built-in way to do it.

  • StackOverflowException in c# when no local variable in the function

    - by dnkulkarni
    when i do this static void Main() { Main(); } I receive stackoverflow exception. As i have read so far about C# they say ONLY local variable of value types (and short living ones) will go on stack. But here in the code there are no local variable to go on stack then what overflows it ? I know from assembly code line Perspective that reference to Main() will go on stack too ? Is that right ?

  • Is it possible to return as SiteMap as a JsonResult?

    - by Paul Suart
    I've got a very simple Action on my Controller that's attempting to return my XmlSiteMap as a JsonResult: public ActionResult Index() { var nodes = SiteMap.Provider.RootNode; return new JsonResult() { Data = nodes, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; } However, when I call the Action, an InvalidOperationException is thrown: "A circular reference was detected while serializing an object of type 'System.Web.SiteMapNode'." Is there a way to Json serialize a SiteMap, or indeed any object that has children of the same type?

  • Targeting Android with Scala 2.8 Trunk builds

    - by Kevin Wright
    The definitive reference for using Scala on android seems to be here: http://www.scala-lang.org/node/160 Unfortunately, all the references on using scala with android are based around Scala 2.7 and refer to a custom build android-library.jar, with a couple of cryptic references suggesting that this custom build isn't needed for later versions of android (I'm using 2.1 / API v7) So... What are the steps needed to use Scala 2.8 in an android project? Preferably using eclipse and the Android tools that Google supplies for that IDE.

  • How to get ANTLR 3.2 to exit upon first error?

    - by Dan Becker
    In section 10.4, The Definitive ANTLR reference tells you to override mismatch() & recoverFromMismatchedSet() if you want to exit upon the first parsing error. But, at least in ANTLR 3.2, it appears that there is no mismatch() method, and the recoverFromMismatchedSet() documentation says that it is "Not Currently Used". So it appears things have changed since the book was published. What am I supposed to do instead to exit upon the first parsing error in ANTLR 3.2?

  • Is there a way to debug ASP.NET MVC code using a symbol server (instead of downloading the source an

    - by Pure.Krome
    Hi folks, Is it possible to step through the official ASP.NET MVC 2 code via using the Symbol Server thingy in visual studio 2010? I know I can download the full open source MVC code from codeplex, build it and then get my code to reference THAT codebase dll's... But i'm wondering if this could be achieved by using the Symbol Server stuff instead? If so, can someone go through some steps please, about how to achieve this?
