java - Unicode Regex in Scala REPL -


मुझे यूनिकोड पत्र ( \ p {L} ) के शब्द पता लगाना है।

स्काला का आरईपीएल निम्नलिखित कथन के लिए false वापस देता है, जबकि जावा में यह true है (जो सही व्यवहार है):

Java.util.regex.Pattern.compile ("\\ p {L}")। मैटचर ("ए")। मैचों ()

जावा और स्कला दोनों JRE में चल रहे हैं 1.7:

System.getProperty ("java.version") देता है "1.7.0_60-ea"

क्या इसके लिए कारण हो सकता है?

संभवतः दुभाषिए के भीतर उपयोग किए जाने वाले गैर-संगत वर्ण एन्कोडिंग । उदाहरण के लिए, यहां मेरा आउटपुट है: 

  scala & gt; System.getProperty ("file.encoding") res0: स्ट्रिंग = UTF-8 स्केल & gt; Java.util.regex.Pattern.compile ("\\ p {L}")। मैटचर ("ए")। मैचों () res1: बूलियन = सच

तो समाधान है scala के साथ -dfile.encoding = UTF-8 को चलाने के लिए। नोट, हालांकि, (जो थोड़ी पुरानी है):

स्काला के लिए डिफ़ॉल्ट वर्ण एन्कोडिंग सेट करने के लिए केवल एक ही विश्वसनीय तरीके से आपके आवेदन को चलाने से पहले $ JAVA_OPTS सेट करना है:

$ JAVA_OPTS = "- Dfile.encoding = utf8" scala [...] बस scala -file.encoding = utf8 सेट करने की कोशिश कर रहा है ऐसा करने लगते हैं [...]

यहां मामला नहीं था, लेकिन यह भी हो सकता है: वैकल्पिक रूप से, आपका "एक" चिह्न "a" द्वारा पीछा किया जा सकता है, जैसे: 

  स्कला & gt; Println ("a \ u0308") स्केल & gt; Java.util.regex.Pattern.compile ("\\ p {L}")। मैटचर ("a \ u0308") मैचों () res1: बूलियन = गलत

यह है कभी-कभी कुछ प्रणालियों पर एक समस्या है, जो कि डायैरिटिक्स बनाते हैं (मुझे लगता है कि ओएस एक्स एक है, कम से कम कुछ संस्करणों में)। अधिक जानकारी के लिए,।

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...

ios - How to determine if NSLayoutConstraint is horizontal or vertical? -

It seems that this should be a simple task, but if a NSLayoutConstraint is a horizontal or vertical The obstacle? The only way to try to make this difference is by [constraint description]; Calling and then the resulting string "V:" or "H:" I want to find this information, because of I have around 2 similar restrictions which are prototype storyboard UITableViewCell , the only difference is that supervision is horizontal Describes the distance, and the second vertical. Any suggestion would be very helpful! Edit: I accepted the reply of Grimozoar because its interpretation is a great answer and the way I am working to parse the details, @ kongtomorrow I also want to give credit, answered me here! Thanks for the help! Here is the real code that I used to find the hindrance: NSArray * constraints = [bubble constraints]; (If ([[obstacle first item]], then e-mail: message labels] and [[barrier is second int.] Is aqual: bubble] and amp; a...

c# - Updated Castle to 3.2.1 from 3.0.0 now I cant use FirstNonGenericCoreInterface -

Image
After I upgraded to 3.2.1 Castle I think I can not find the right replacement for the FirstNonGenericCoreInterface My code container.Register (AllTypes .FromAssemblyNamed ("MySolution.Tasks") .Innamespace ("MySolution.Tasks") .WithService.FirstNonGenericCoreInterface ("MySolution.Domain" )); This method is not obsolete and which method I can not use it Does anybody know what I should use instead? If I'm not mistaken, FirstNonGenericCoreInterface is an intense architecture extension method. WithService.DefaultInterfaces () does that, then what should you do with your implementation class name interface? More information is available at Castle Windsor Wiki
