newline

问题 This question already has answers here : Removing trailing newline character from fgets() input (12 answers) Closed 4 years ago . I am sorry if this question is obvious, or if I am making a simple logic mistake. I have searched for various ways of getting rid of the newline that comes from using fgets, but I continue running into problems while building. I think I am not understanding something properly and applying my "solution" incorrectly. I would like to be transparent and say that this

问题 With Python, I'm saving json documents onto separate lines like this: from bson import json_util # pymongo with open('test.json', 'ab') as f: for document in documents: f.write(json_util.dumps(document)+'\n') and then reading like this: with open('test.json') as f: for line in f: document = json_util.loads(line) The ease and simplicity make me think that there must be a gotcha? Is this all there is to linejson, aka jsonlines? 回答1: Yes, that's all there is to it. 来源： https://stackoverflow.com

问题 This question already has answers here : How do I handle newlines in JSON? (8 answers) Closed 4 years ago . Why can't you parse a json with a \n character in javascript JSON.parse('{"x": "\n"}') However when you do JSON.parse(JSON.stringify({"x" : "\n"})) , it is valid. http://www.jslint.com/ says that {"x": "\n"} is a valid JSON. I wonder what does spec says about this? Update: For those who marked this duplicate, this is not the same question as "How to handle newlines in JSON". This

问题 How can I remove new line inside the " from a file? For example: "one", "three four", "seven" So I want to remove the \n between the three and four . Should I use regular expression, or I have to read that's file per character with program? 回答1: To handle specifically those newlines that are in doubly-quoted strings and leave those alone that are outside them, using GNU awk (for RT ): gawk -v RS='"' 'NR % 2 == 0 { gsub(/\n/, "") } { printf("%s%s", $0, RT) }' file This works by splitting the

问题 try (Stream<String> lines = Files.lines(targetFile)) { List<String> replacedContent = lines.map(line -> StringUtils.replaceEach(line,keys, values)) .parallel() .collect(Collectors.toList()); Files.write(targetFile, replacedContent); } I'm trying to replace multiple text patterns in each line of the file. But I'm observing that "\r\n"(byte equivalent 10 and 13) is being replaced with just "\r"(just 10) and my comparison tests are failing. I want to preserve the newlines as they are in the

How would I do VAR="$VAR\nin a box" , for example? I have

问题 I'm pulling content from a DB that has been sanitized using mysql_real_escape_string. Accordingly the new line characters now appear as "\n". The issue is that this content is displayed to users inside a < pre > tag so I cannot replace \n with < br/> for instance. I suppose I could replace \n with the actual utf8 character code before inserting the result inside the < pre>. Can somoneone assist here? Not using mysql_real_escape_string isn't really an option due to security policy. Thanks. 回答1
