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。

Interpolated raw string literals are defined as: 複製 interpolated_raw_string_literal : single_line_interpolated_raw_string_literal | multi_line_interpolated_raw_string_literal ; interpolated_raw_string_start : $ | $$ | $$$ | etc. ; interpolated_raw_string_literal_delimiter : interpolated_...
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.
Clearly C# 11 raw string literal is a great way to declare much clearer JSON, XML, SQL, test expectations… string literals in code thanks to alignment with the actual nesting: Let’s challenge this new string literal alignment feature. First only whitespace characters are accepted in columns ...
Visual Studio 2022 17.2 adds Raw string literals to C# 11 "Raw string literal" support has been added to C# 11, which you can now use in Visual Studio 2022. To use the raw string literals, you need to set the C# language version in your project file to preview (usingpreview). Visual...
https://clang.llvm.org/cxx_status.html currently claims that P2558R2 is implemented. However, per [lex.string], @, $, and ` need to be usable as d-chars since C++26, and Clang doesn't accept the newly permitted raw string literals yet. G...
When dealing with lots of escape sequences in strings, it would be nice if there was possibility to do conversion to and from raw string literals. So I would like to be able to convert from: const char* s1 = "a\\b\\c\\d"; const char* s2 = "\nHello\n World\n"; to const ...
Raw string literals can be interpolated by preceding them with a$. The number of$that prefixes the string is the number of curly brackets that are required to indicate a nested code expression. This means that a$behaves like the existing string interpolation – a single set of curly brackets...
A string literal is an *lvalue*; all other literals are *rvalues*. -4- The operator :: followed by an identifier, a qualified-id, or an operator-function-id is a primary-expression. Its type is specified by the C / C++ 16 17660 sizeof( <string literal> ) by: Don Starr |...
