问题 I just faced this question in interview. Is it possible to escape character within single quotes in ruby? The confusion is in following code puts '\\' # Output: \ puts '\n' # Output: \n It seems that backword slash is escaped but the newline character isn't. I am aware of this question but I am not asking about difference between single and double quote. I am asking about whether it's possible to escape characters in single quotes or not? And why only backslash is allowed to escape? 回答1: The

问题 I wrote a linux bash script with tee and grep to log and timestamp the actions I take in my various ssh sessions. It works, but the logged lines are mixed together sometimes and are full of control characters. How can I properly escape control and other characters not visible in the original sessions and log each line separately? I am learning bash and the linux interface, so any other suggestions to improve the script would be extremely welcome! Here is my script (used as a wrapper for the

问题 I am trying to return a JSON response with text that may contain double quotes in them. For example "12.10 On-Going Submission of ""Made Up"" Samples." I have escaped the double quotes using StringEscapeUtils.escapeJava(artifact.text); which perfectly escapes the quotes \"12.10 On-Going Submission of \"\"Made Up\"\" Samples.\" But the JSON response is truncated { "documentName":"ICENSE AGREEMENT6", "listOfArtifacts":[ { "type":"Clause", "artifacts":[ { "documentId":6951, "documentName":

Can we escape < in markdown code blocks embedded in HTML? The goal: a class that escapes < , allowing that class to contain the text <html>, <body>, <head>, <script>, <style>, <body>, and

问题 I am attempting to write a python script that converts a .properties file (as read by Ant), and converts the result into a dictionary, mapping keys to values.

As I am using python 3 (specifically, python 3.6), I use value = value.encode('utf-8'

问题 The MySQL documentation says that it should be \' . However, both scite and mysql shows that '' works. I saw that and it works. What should I do? 回答1: The MySQL documentation you cite actually says a little bit more than you mention. It also says, A “ ' ” inside a string quoted with “ ' ” may be written as “ '' ”.

So I got an array containing country codes. I got a 700mb file with thousand of rows starting with the country code. I want to split the file into several files depending on this country code.
