strange ruby syntax for rails devise helper -

इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 2 जवाब

मैंने निम्नलिखित कोड को देखा deviser_helper.rb। & Lt; & lt; -HTML ... HTML का मतलब यहां है: 

  html = & lt; & lt; -HTML & lt; div id = "error_explanation" class = "alert" & gt; & LT; h2 & gt; # {वाक्य} & lt; / h2 & gt; & LT; ul & gt; # {संदेशों} & lt; / ul & gt; & Lt; / div & gt; एचटीएमएल

रूबी में एम्बेडेड एचटीएमएल कोड लिखने का एक शानदार तरीका है। लेकिन यह क्यों काम करता है और यह कहां से आता है?

यह सिर्फ एक है। आमतौर पर इसे एक या यहाँ दस्तावेज़ कहा जाता है लिंक किए गए प्रलेखों से:

एक & lt; & lt; आप तार को समाप्त करने के लिए स्ट्रिंग या पहचानकर्ता को निर्दिष्ट कर सकते हैं, और टर्मिनेटर तक की वर्तमान रेखा के सभी रेखाएं स्ट्रिंग का मान हैं।

- & lt; & lt; के बाद आप टर्मिनेटर इंडेंट कर सकते हैं, ताकि HTML अंत में उसके पहले रिक्त स्थान या टैब हो सकते हैं।

Here is my code: Process TForm1.FormCreate (From: TObject); Var myFile: textfile; Line: String; Start AssignFile (myFile, '~ / changelog.txt'); Reset (myFile); While EOF (MyFile) does not readLn (myFile, Line); Label3.Caption: = (Label3.Capttion + Line + # 13 # 10); End; CloseFile (myFile); End; This does not work, however, if I replace ~ with the actual user name, then it works, however, I use the username of each user Can not know which will run my program.
