trailing

问题 The contents of stdin is getting corrupted with word wrapping and trailing "=" throughout which obviously breaks the URL that I need to post. I need to extract a URL/link from an email then post the URL. So, I'm piping my email to a php script in cpanel using a standard code snip I've seen all over the internet: $fd = fopen("php://stdin", "r"); $email = ""; // This will be the variable holding the data. while (!feof($fd)) { $email .= trim(fread($fd, 1024)); } fclose($fd); Then dumping the

问题 I find a lot of answers to this question (and I have read dozens of them), but they are all about more advanced stuff with patterns and such stuff. I just need a very simple and basic redirect for static urls. If I add a trailing slash to the url, the redirect doesn't work and I just can't figure out why. Example: RewriteEngine On Redirect 301 /content https://www.example.com/site/content.html Redirect 301 /content/ https://www.example.com/site/content.html https://example.com/content does

问题 I have some code like this $editStuState = StuAtt::where('studentId' , '=' , $id)->first(); $editStuState -> leave +=1; $editStuState -> present = $editStuState -> present-1; $editStuState->update(); //OR $editStuState->save(); return 'this is good'; I can't save or Update my data, when I remove Update and Save related line it can print text. this is the dd($editStuState) data StuAtt {#382 ▼ #table: "stu_attendance" #connection: "mysql" #primaryKey: "id" #keyType: "int" +incrementing: true

问题 I have a markdown file with lines that have trailing whitespace (which is correct and should be commited). I'm unable to add these changes using git add -p to the index because git complains about trailing whitespace. They are added correctly if I use git add -A , but I want it to work with git add -p . I have in my ~/.gitconfig : [core] whitespace = trailing-space,space-before-tab This has been working fine since for the most part I DO want to warn on trailing whitespace (it is incorrect in

问题 I have several alphanumeric strings like these listOfNum = ['000231512-n','1209123100000-n00000','alphanumeric0000', '000alphanumeric'] The desired output for removing trailing zeros would be: listOfNum = ['000231512-n','1209123100000-n','alphanumeric', '000alphanumeric'] The desired output for leading trailing zeros would be: listOfNum = ['231512-n','1209123100000-n00000','alphanumeric0000', 'alphanumeric'] The desire output for removing both leading and trailing zeros would be: listOfNum =

问题 I am trying to get user input, parse it and then display with String.Format(), formatting thousands with comas. So, if user provides 1000 I will display 1,000 1000.00 => 1,000.00 1000.0 => 1,000.0 1,000.5 => 1,000.5 Basically I want to keep all decimals(including trailing zeroes) that were provided and just add formatting for thousands. I tried: String.Format("{0:#,0.######}" , Decimal.Parse(input)); String.Format("{0:#,0.######}" , Double.Parse(input); 回答1: double.Parse(input) is a no go, as

问题 Is there any way of to remove the trailing whitespace after entered a decimal? E.g.: 10 A I want to catch the first character after the whitespace ends. (Which gotta be \n to be true. if not, then false My attempt so far: cout << "Please enter a number: "; cin >> n; if (cin.peek() == ' ') //Something to catch the whitespaces if(cin.fail() || cin.peek() != '\n') cout << "Not a number." << endl; else cout << "A number." << endl; Possible to do that by functions in istream? (I know cin.fail can

问题 I want to remove the trailing slash from a string in Java. I want to check if the string ends with a url, and if it does, i want to remove it. Here is what I have: String s = "http://almaden.ibm.com/"; s= s.replaceAll("/",""); and this: String s = "http://almaden.ibm.com/"; length = s.length(); --length; Char buff = s.charAt((length); if(buff == '/') { LOGGER.info("ends with trailing slash"); /*how to remove?*/ } else LOGGER.info("Doesnt end with trailing slash"); But neither work. 回答1: There

问题 I'm looking for a bash command to find files with trailing spaces at the end of each line. I'm not interested in removing the spaces, but just in finding the files. 回答1: Find files that has trailing spaces. find . -type f -exec egrep -l " +$" {} \; 回答2: If the goal is to list files which have trailing whitespaces in one or more lines: grep -r '[[:blank:]]$' . To not print the lines, and print just the file names only, also specify the -l option. That's l as in the word list , not the number 1

问题 What is the function that removes trailing zeros from doubles? var double = 3.0 var double2 = 3.10 println(func(double)) // 3 println(func(double2)) // 3.1 回答1: In Swift 4 you can do it like that: extension Double { func removeZerosFromEnd() -> String { let formatter = NumberFormatter() let number = NSNumber(value: self) formatter.minimumFractionDigits = 0 formatter.maximumFractionDigits = 16 //maximum digits in Double after dot (maximum precision) return String(formatter.string(from: number)
