Reflection in Rebol: Is it possible to know the script/object/function that is executing? -

यदि आर 3 में यह संभव नहीं है?

हाँ और नहीं।

तकनीकी तौर पर, नहीं ..... फ़ंक्शंस के नाम नहीं हैं, वे अनाम हैं एक ही समारोह एक से अधिक शब्द को सौंपा जा सकता है, इसलिए वास्तविक नाम समस्याग्रस्त है। 

  do func [] [प्रिंट "हे विश्व"] ;; इस फ़ंक्शन का स्पष्ट रूप से सभी नामों पर कोई नाम नहीं है: फ़्ंटक [] [प्रिंट "यो विश्व"] ;; यहां तीन नामों के साथ एक समारोह है f2:: f1 f3:: f2

कुछ मामलों में अभ्यास में, हां .... आप वर्तमान नाम (यदि कोई है) को पकड़ कर सकते हैं एक चाल: एक त्रुटि को कैप्चर करें, और त्रुटि ऑब्जेक्ट में स्टैक पर नाम होता है: 

  f3: func [/ स्थानीय ईओ] [ईओ: निहृ € ा प्रयास करें [0/0] प्रिंट ["नाम है "ईओ / कहां]] एफ 4:: एफ 3   <पी> इसे आज़माएं:  
  & gt; & gt; एफ 3 नाम एफ 3 है & gt; & gt; एफ 4 नाम एफ 4 है  
 
 यहां एक व्यापक चर्चा है:

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...
