In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
Clang – The free Clang project includes a static analyzer. As of version 3.2, this analyzer is included in Xcode. [14] Infer – Developed by an engineering team at Facebook with open-source contributors. Targets null pointers, leaks, API usage and other lint checks.
Clang 1.0 released, with LLVM 2.6 for the first time. December 2009: Code generation for C and Objective-C reach production quality. Support for C++ and Objective-C++ still incomplete. Clang C++ can parse GCC 4.2 libstdc++ and generate working code for non-trivial programs, [20] and can compile itself. [36] 2 February 2010: Clang self-hosting ...
A free-format language ignores whitespace characters: spaces, tabs and new lines so the programmer is free to style the code in different ways without affecting the meaning of the code. Generally, the programmer uses style that is considered to enhance readability. The two code snippets below are the same logically, but differ in whitespace.
Racket is a cross-platform language toolchain including native code, JIT and JavaScript compiler, IDE (in addition to supporting Emacs, Vim, VSCode and others) and command line tools designed to accommodate creating both domain-specific and general purpose languages. [14] [15]
All code formatted in the GNU style has the property that each closing brace, bracket or parenthesis appears to the right of its corresponding opening delimiter, or in the same column. Being tightly integrated with the GNU system, GNU Emacs provides automatic formatting of C code to match the GNU coding standards. [ 1 ]
The combination of the Clang frontend and LLVM backend is named Clang/LLVM or simply Clang. The name LLVM was originally an initialism for Low Level Virtual Machine . However, the LLVM project evolved into an umbrella project that has little relationship to what most current developers think of as a virtual machine .
GCC and Clang are two major C compilers popular today, both based on the C11 with updates including changes from later specifications such as C17. [ 29 ] [ 30 ] Any source code written only in standard C and without any hardware dependent assumptions is virtually guaranteed to compile correctly on any platform with a conforming C implementation.
