newline

问题 Recently some customers complained that they were getting garbled emails. MIME headers were showing, and base64 encoded data, etc. Stuff that should have been decoded by their mail clients. After investigating I found that some mail clients (gmx.de webmail to name one) inserted a blank line after every other line, thus indeed messing everything up. Following a hunch, I changed my mail sending code to replace all CRLF with just LF. And lo and behold - the mail arrived whole. Now, this is weird

问题 I got the following problem, I read data string from an API which contains new line characters \n and I want to display them correctly in my template. But when I do something like: <p>{{ mytext }}</p> The text is display with \n characters in it like normal text. The text string from the response is in the format of "Hello, \n what's up? \n My name is Joe" . What am I doing wrong here? 回答1: Not even a vue issue you could simply use CSS and apply white-space: pre; to the content. You shouldn't

问题 I have a .txt file created in Windows and now should be edited in Linux. I want to match end of a line with grep, let's say content of the line I gonna to find is "foo bar" in file bar . Then I issue the command grep 'r$' bar , no output yielded. Given in Windows a new line consists of '\r\n', different from Linux/Unix a single '\n', I think there must be something subtle related to this. Then I convert the file with dos2unix and voila, it works. My question is how can I match the content

问题 Using Powershell v2 called from a batch file, I want to replace each CRLF in a file with just an LF. If a file only has LF without any CR, then I want all the LF to be left alone. I do not want a terminating CRLF in the resultant file, if possible. I found this question here on Stack Overflow, that seems to be a close match, but it does not specify a Powershell version requirement, nor does it specify the other criteria above. Hence this question. The accepted answer for that question

问题 I'm using cygwin on Windows 7, but I've decided to work with msysgit instead of default cygwin git, because msysgit is always more recent. Everything works pretty well, except commit message editing. I'm using nano (form cygwin) and my msysgit is apparently sending an CRLF line endings to it, therefore they are displayed incorrectly in cygwin window (as ^M ). Have you got any idea how to fix this? Do you think that combining mssygit and cygwin is good approach anyway? Thanks! 回答1: Do you

问题 I am trying to add a a couple of authors to a report I am writing. Preferably, the second author would appear on a new line after the first. I know I can modify the template to add a new field or the multiple author example given in the Pandoc readme. However, I wonder if there is any character I can use to insert a new line between authors directly in the metablock. So far I have tried \newline , \\ , | with newline and space, <br> , <div></div> , and making the author list a string with

问题 Having read the following description of this feature of Bash (excerpt from the man page): Here Strings A variant of here documents, the format is: <<<word The word is expanded and supplied to the command on its standard input. I expected that the interpretation of here strings is that Bash simply passes the contents of a variable directly on a command's standard input, unmodified. Following this logic, the lines [1] and [2] below would be effectively equivalent. [1]~$ printf foo | cat - <

问题 I am trying to simply read words in a text file using scanner.next() with delimiter equal " " but the scanner includes the newline/carriage return with the token. I have scoured the internet trying to find a good example of this problem and have not found it so I am posting it here. I can't find another similar problem posted here on SO. I also looked over the documentation on scanner and pattern (http://docs.oracle.com/javase/1.5.0/docs/api/java/util/regex/Pattern.html) but I still cannot

问题 I'm trying to collect information from a textfile which contains names of organisations (without spaces) and floating integers. I want to store this information in an array structure. The problem I'm having so far is collecting the information. Here is a sample of the textfile: CBA 12.3 4.5 7.5 2.9 4.1 TLS 3.9 1 8.6 12.8 4.9 I can have up to 128 different numbers for each organisation, and up to 200 organisations in the textfile. This is what my structure looks like so far: struct callCentre

问题 I am using Python 3 and am trying to use my print statements with the str.format. e.g: print ('{0:3d} {1:6d} {2:10s} '.format (count1,count2,string1)) When I try to use the end='' to suppress the subsequent newline, this is ignored. A newline always happens. How do I suppress the subsequent newline? Source: int1= 1 int2 = 999 string1 = 'qwerty' print ( '{0:3d} {1:6d} {2:10s} '.format (int1,int2,string1)) print ('newline') print ( '{0:3d} {1:6d} {2:10s} '.format (int1,int2,string1,end=''))
