问题 I have a Jekyll folder in which only the production part ( _site ) is tracked with git. When I run the command to serve the local site with jekyll serve -w , the files will be changed to LF or CRLF depending on the machine I'm working on: CRLF for Windows, LF for Mac. This is really annoying because all my files inside _site will be commited everytime I switch my OS. I've tried to fix this in the git config file with autocrlf = false , but since the files are generated at a higher level by

问题 I have a Smarty Loop as below, for e.g: {strip} {assign "comma" ""} {foreach from=$List item=Item} {$comma}{$Item.title} {assign "comma" ","} {/foreach} {/strip} .. from which I EXPECT is: Apple, Banana, Candy .. WRITTEN as a FILE. My PHP codes (to write the file) are: $f = fopen('myfile.txt', 'w'); fwrite( $f, $smarty->fetch('sample.tpl') ); But instead IN REALITY , it is being written as like below: Apple,Banana,Candy Even if i use \r or \r\n in Smarty tpl , they are just being printed out,

问题 Just to illustrate the problem I have taken a testset csv file. But in real case scenario, the problem has to handle more than a TeraByte data. I have a CSV file, where the columns are enclosed by quotes("col1"). But when the data import was done. One column contains new line character(\n). This is leading me to lot of problems, when I want to save them as Hive tables. My idea was to replace the \n character with "|" pipe in spark. I achieved so far : 1. val test = sqlContext.load( "com

问题 My program prints a large number of short lines to cout . As a slightly contrived example, my lines look a little like this: cout<<"The variable's value is: "<<variable<<endl; I'd like the program to run fast and I do believe that endl is killing me because it initiates a buffer flush on cout every time it is used. Now, some folks on the internet have said that I could do this instead: cout<<"The variable's value is: "<<variable<<"\n"; But this does not seem like a good solution because endl

问题 What should I see when I use the following? System.out.println("LineSeperator1: "+System.getProperty("line.separator")); System.out.println("LineSeperator2: "+System.lineSeparator()); I get the following back: LineSeperator1: LineSeperator2: Is it empty? invisible? shouldn there be something like \r or \n ? I use windows 7, eclipse and jdk 1.8. 回答1: As you expect, the line separator contains special characters such as '\r' or '\n' that denote the end of a line. However, although they would be

问题 How do I know when I can use a New Lines/Carriage returns in my Powershell scripts? All of the search results when searching for this answer all point to the Output. I don't care about the output in this case. I am more interested in my ability to format my Powershell scripts for readability. For Example. Two versions of a Powershell command line below. One works and one doesn't. What the command does in unimportant in this case. The point is I am needing to know when I'm allowed to create a

问题 I have this form generation code..: $form = $this->createFormBuilder($task) ->add('mode', 'choice', array( 'label' => false, 'choices' => array( 'mode1' => '1', 'mode2' => '2', 'mode3' => '3', ), 'multiple' => false, 'expanded' => true, 'required' => true, )) ->getForm(); The problem is that rendered form has choices (radio inputs) inline, without <br/> tags between them. Also, i cannot find how do i render form with a twig template so do not touch PHP code, for example, how can i specially

问题 I have been having issues with a newline appearing in my browser output with Codeigniter. What happens is I am outputting JSON data, but there is a newline character before any of the JSON data, and it is messing stuff up. 回答1: Likely you have some whitespace at the end of one of your PHP files. It is a pretty common problem if you use the closing tag ?> . You'll want to search your code files and look for a ?> with a newline character after it. Anything after a closing tag gets output to the

问题 I want to implement a grid with the cells that have the following behaviour: cell text should be wrapped if it doesn't fit to the cell newlines (\n) in the cell text should be processed as well i.e. the same behaviour as in table editors like MS Excel, OO Calc, etc. when you enable the 'wrap words' option for cells. I'm trying to do this as follows: import wx import wx.grid class MyGrid(wx.grid.Grid): def __init__(self, parent = None, style = wx.WANTS_CHARS): wx.grid.Grid.__init__(self,

问题 When you run something through popen in Python, the results come in from the buffer with the CR-LF decimal value of a carriage return (13) at the end of each line. How do you remove this from a Python string? 回答1: You can simply do s = s.replace('\r\n', '\n') to replace all occurrences of CRNL with just NL, which seems to be what you want. 回答2: buffer = "<text from your subprocess here>\r\n" no_cr = buffer.replace("\r\n", "\n") 回答3: If they are at the end of the string(s), I would suggest to
