Python 支持所谓的 “raw string”,它最大的特点就是将反斜杠视为文字字符。 C++11 也新增了一种叫原始字符串(Raw String Literals)的类型。在原始字符串中,字符表示的就是它自己,而无需使用 "\" 转义,例如,"\n" 不表示换行符,而是表示两个常规字符:"\" 和 "n",这时使用 "\n" 将不再输出换行符。
Raw string literals make it easier to work with database querying strings, regular expressions, file paths, and so on. Regular expressions are discussed in Chapter 21, “String Localization and Regular Expressions.”
std::string my_string = R"foo(This contains quoted parens "()")foo"; 对于我们大多数人来说,原始字符串字面量当然不是日常工具,但在某些时候,恰当地使用这个新语言特性将会增加代码的可读性。所以下一次当你头疼于是否需要两个 \ 或四个 \ 时,试试原始字符串字面量吧。即使正则表达式仍然很难,你的...
这几天看C# 11的新语法,学习到了Raw string literals 今天给大家分享一下: 原始字符串是字符串的一种新格式。 原始字符串可以包含任意文本,包括空格、新行、嵌入引号和其他特殊字符,无需转义字符(这个很关键、也很简单)。 原始字符串以至少三个双引号 (""")字符开头。 它以相同数量的双引号字符结尾。 通常,...
原始字符串字面值(raw string literal)是C++11引入的新特性。 原始字符串简单来说,“原生的、不加处理的”,字符表示的就是自己(所见即所得),引号、斜杠无需 “\” 转义,比如常用的目录表示,引入原始字符串后,非常方便。 格式如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 R"(原始字符串)...
Raw string literals can contain any arbitrary text without the need for special escape sequences. You begin and end a raw string literal with a minimum of three double-quote characters.
What:Turn any string into a C++ raw string literal. When:You have a string with escaped characters, which shouldn't be processed as escaped characters. Why:You could double-escape characters, but this often leads to confusing and strings. Raw string literals make strings much easier to read....

https://clang.llvm.org/cxx_status.html currently claims that P2558R2 is implemented. However, per [lex.string], @, $, and ` need to be usable as d-chars since C++26, and Clang doesn't accept the newly permitted raw string literals yet. G...
Raw string literals If you work with strings literal that contain quotes or embedded language strings like JSON, XML, HTML, SQL, Regex and others,raw literal stringsmay be your favorite feature of C# 11. Previously if you copied a literal string with quotes into a C# literal, the string en...
