问题 I've been seeing this issue on Windows. When I try to clear any whitespace on each line on Unix: const input = `=== HELLO WOLRD ===` console.log(input.replace(/^\s+$/gm, '')) This produces what I expect: === HELLO WOLRD === i.e. if there were spaces on blank lines, they'd get removed. On the other hand, on Windows, the regex clears the WHOLE string. To illustrate: const input = `=== HELLO WOLRD ===`.replace(/\r?\n/g, '\r\n') console.log(input.replace(/^\s+$/gm, '')) (template literals will

问题 I insert data that contains a line feed character into the database. Then I retrieve that data. I am using this script to attempt to remove the line feed while selecting the data from SQL: Select Replace(Replace stringname,char(10),'',char(32),'')) from tablename The replace function seems to execute, but it does not remove the line feed correctly. 回答1: The syntax of your statment looks wrong, maybe you can try with something like this: Select Replace(Replace(@str,CHAR(10),''),CHAR(13),'')

问题 I am creating a C# UWP application and I have noticed that the line feed (\n) character is missing from the output text when I enter it into a Textbox. When I press enter into my Textbox it produces CR+LF character (\r\n). what can I do to bring the textbox behavior to notice both CR+LF & LF. I have set AcceptReturn = "true" and I have even tried replacing \n with \r\n but that doesn't work either. 回答1: As @lindexi said the new TextBox used \r as line feed character in Windows 10 build 15063.

问题 I am working on an ANTLR4 grammar for parsing Python DSL scripts (a subset of Python, basically) with the target set as the Python 3 . I am having difficulties handling the line feed. In my grammar, I use lexer::members and NEWLINE embedded code based on Bart Kiers's Python3 grammar for ANTLR4 which are ported to Python so that they can be used with Python 3 runtime for ANTLR instead of Java. My grammar differs from the one provided by Bart (which is almost the same used in the Python 3 spec)

问题 Is there a way to write several lines to the system console in Windows, then delete or modify them, using Java? I can write over the same line more than once using the \r carriage return character. The Cygwin command less (a text viewer) manages it (although it's not Java), so I suspect it's possible. I've tried \u008D which is (according to a page I googled) the reverse line feed character, but it doesn't seem to work. System.out.println("1"); System.out.println("2"); System.out.print("

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 I have a .txt file where I need to get rid of the last line feed. Looking at the file in a HEX Editor it shows "0d 0a" at the end. I have looked at the thread How to delete Linefeed using batch file but that did not help. I have tried COPY source target /b which also does not help. Unfortunately I can't use Java or any third party tools, I need to use a batch file. Does anyone have an idea how to get rid of that line feed at the end? Thank you very much and best regards, Peter 回答1: Using

问题 Here is a simple script called command.sh : #!/bin/bash echo "I received: |$1|" When I call it with a line feed, it doesn't output it: $ ./command.sh foo\ > bar I received: |foobar| Why does the line feed get lost? 回答1: Call your script as: ./command.sh 'foo > bar' By placing \ before newline you're merely breaking current command line and not really passing newline character to your script. If you want to do it in single line then use: ./command.sh $'foo\nbar' 来源： https://stackoverflow.com
