On June 15, 2021 Next.js version 11 was released, introducing among others: Webpack 5 support, preview of real-time collaborative coding functionality "Next.js Live", and experimental function of automatic conversion from Create React App to Next.js compatible form "Create React App Migration". [23]
Typically compiler directives define or "undefine" certain variables; other directives test these variables and modify compilation accordingly. For example, not using an actual language, the compiler may be set to define "Macintosh" and undefine "PC", and the code may contain:
Server Side Includes (SSI) is a simple interpreted server-side scripting language used almost exclusively for the World Wide Web.It is most useful for including the contents of one or more files into a web page on a web server (see below), using its #include directive.
For example, coding: UTF-8 indicates that the file is encoded via the UTF-8 character encoding. In C#, compiler directives are called pre-processing directives. There are a number of different compiler directives including #pragma, which is specifically used to control compiler warnings and debugger checksums. [5] [6]
The second edition of the C Standard, C99, added support for __func__, which contains the name of the function definition within which it is contained, but because the preprocessor is agnostic to the grammar of C, this must be done in the compiler itself using a variable local to the function.
Generally, for C/C++ the include directive is used to include a header file, but can include any file. Although relatively uncommon, it is sometimes used to include a body file such as a .c file. The include directive can support encapsulation and reuse. Different parts of a system can be segregated into logical groupings yet rely on one ...
Emscripten is an LLVM/Clang-based compiler that compiles C and C++ source code to WebAssembly, [4] primarily for execution in web browsers. Emscripten allows applications and libraries written in C or C++ to be compiled ahead of time and run efficiently in web browsers, typically at speeds comparable to or faster than interpreted or dynamically ...
In the C and C++ programming languages, an #include guard, sometimes called a macro guard, header guard or file guard, is a way to avoid the problem of double inclusion when dealing with the include directive. The C preprocessor processes inclusion directives like #include "foo.h" to include "foo.h" and transcludes the code of that file into a ...
