multithreading - How are Atoms implemented in Clojurescript? -


लिखने के लिए मुद्दों में: 

  user = & gt; (Def my-atom (atom 0)) # 'user / my-atom user = & gt; @ माइ-एटम 0 उपयोगकर्ता = & gt; (स्वैप! माइ-एटॉम इंक) 1 उपयोगकर्ता = & gt; @ माइ-एटम 1 उपयोगकर्ता = & gt; (स्वैप! माइ-एटॉम (एफ एन [एन] (* (+ एन एन) 2)) 4)   
 हम जानते हैं कि यह (क्लोज़र कार्यान्वयन में) है  
 दिलचस्प रूप से पर्याप्त, परमाणु, एक सिंटैक्टिक स्तर पर - भले ही जावास्क्रिप्ट रनटायम्स में कोई परमाणु संदर्भ नहीं है  
 मेरा प्रश्न यह है कि,  कैसे क्लॉजस्क्रिप्ट में एटम का कार्यान्वयन किया जाता है?  क्या वे सिर्फ एक वस्तु आवरण हैं?   
 
  
  स्वैप!  और  रीसेट!  के कार्यान्वयन की जांच करें आपको पता चल जाएगा:  
  (सेट! (.- राज्य ए ) नया   
   
 फिर,  सेट पर जाएं! , आप पाएंगे कि संकलक सिर्फ एक असाइनमेंट कथन का उत्सर्जन करता है:  
  (defmethod emit *: सेट! [{: Keys [target val env]}] (emit-wrap env (लक्ष्य "=" val)))    < / html>

Android - Facebook GraphUser has no email attribute -

I checked online sources about this issue and checked it twice - but I still get the email attribute Can not Facebook Response As indicated on the launch, I have applied the permissions ("original_third", "email", "user_bridade") to read on the login buttons. Also set the same permissions when creating a session (session .createFromExistingAccessToken). However, on the callback function, when the GraphUser and Response object is logged, I was still not able to retrieve the user's email. Why the error still persists, what are the possible reasons for this? Am I missing some steps? ** onCreate () ** ((Login button) ViewById (R.id.dialog_generic_footer_button_fblogin)) .setPublishPermissions (FBSessionV2.getPermissions ()); String & gt; GetPermissions () {if (permissions.ISTT)} {PERMISSIONS.add ("basic_info"); PERMISSIONS.add ("email"); PERMISSIONS.add ("publish_actions"); PERMISSIONS.add ("user_birthda...

Opencart and VQMOD issue: Could not load controller in vq2-system_engine_controller.php -

I am using Opencart 1.5.6.1 and VQMOD 2.4.1. I have installed the Ewe Rapid 3.0 extension now and at checkout, I get this error: Notice: Error: Controller payment / EVE could not be loaded! On line 47 trigger_error ('Error: Could not load controller'. ($) At $ ($) ... \ vqmod \ vqcache \ vq2-system_engine_controller.php in line children! '!'); I'm not sure whether this is anything with the VQMD or EVE extension. How to fix this? Steps to try: Check if you have a eway.php in the list / controller / payment folder Verify the square name of that file: Class Controller Payment and Controller { . Check file permissions. It's a good day!
