Programming language implementation

In computing, a compiler is software that translates computer code written in one programming language (the source language) into another language (the target language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language (e.g. assembly language, object code, or machine code) to create an executable program.

any low-level programming language in which there is a very strong correspondence between the instructions in the language and the architecture's machine code instructions

program that executes source code without a separate compilation step

software that emulates an entire computer, often used to provide a different operating system or hardware architecture than the host system

computer system program which produces loadable and executable programs from object files or libraries, compiled and assembled separately

In computer science, a preprocessor (or precompiler) is a program that processes its input data to produce output that is used as input in another program. The output is said to be a preprocessed form of the input data, which is often used by some subsequent programs like compilers. The amount and kind of processing done depends on the nature of the preprocessor; some preprocessors are only capable of performing relatively simple textual substitutions and macro expansions, while others have the power of full-fledged programming languages.

In computer programming, the block starting symbol (abbreviated to .bss or bss) is the portion of an object file, executable, or assembly language code that contains statically allocated variables that are declared but have not been assigned a value yet. It is often referred to as the "bss section" or "bss segment".

Ragel (IPA: ) is a finite-state machine compiler and a parser generator. Initially Ragel supported output for C, C++ and Assembly source code, later expanded to support several other languages including Objective-C, D, Go, Ruby, and Java. Additional language support is also in development. It supports the generation of table or control flow driven state machines from regular expressions and/or state charts and can also build lexical analysers via the longest-match method. Ragel specifically targets text parsing and input validation.
