Assembly languages let programmers use symbolic addresses, which the assembler converts to absolute or relocatable addresses. Most assemblers also support macros and symbolic constants.

Embeddable languages


In source code

Source embeddable languages embed small pieces of executable code inside a piece of free-form text, often a web page. Client-side embedded languages are limited by the abilities of the browser or intended client. They aim to provide dynamism to web pages without the need to recontact the server. Server-side embedded languages are much more flexible, since almost any language can be built into a server. The aim of having fragments of server-side code embedded in a web page is to generate additional markup dynamically; the code itself disappears when the page is served, to be replaced by its output.

In object code

A wide variety of dynamic or scripting languages can be embedded in compiled executable code. Basically, object code for the language's interpreter needs to be linked into the executable. Source code fragments for the embedded language can then be passed to an evaluation function as strings. Application control languages can be implemented this way, if the source code is input by the user.

Functional programming In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions tha ...
languages define programs and subroutines as mathematical functions and treat them as first-class. Many so-called functional languages are "impure", containing imperative features. Many functional languages are tied to mathematical calculation tools. Functional languages include:

The activation of specific electrical inputs (e.g., CPU package pins for microprocessors), and logical settings for CPU state values, control the processor's computation. Individual machine languages are specific to a family of processors; machine-language code for one family of processors cannot run directly on processors in another family unless the processors in question have additional hardware to support it (for example, DEC VAX processors included a PDP-11 compatibility mode). They are (essentially) always defined by the CPU developer, not by 3rd parties. The symbolic version, the processor's

Macro languages


Textual substitution macro languages

Macro languages transform one source code file into another. A "macro" is essentially a short piece of text that expands into a longer one (not to be confused with hygienic macros), possibly with parameter substitution. They are often used to preprocess source code. Preprocessors can also supply facilities like file inclusion. Macro languages may be restricted to acting on specially labeled code regions (pre-fixed with a # in the case of the C preprocessor). Alternatively, they may not, but in this case it is still often undesirable to (for instance) expand a macro embedded in a string literal, so they still need a rudimentary awareness of syntax. That being the case, they are often still applicable to more than one language. Contrast with source-embeddable languages like PHP, which are fully featured. * cpp (the C preprocessor) * m4 (originally from AT&T, bundled with Unix) * ML/I (general-purpose macro processor)

Synchronous languages

Synchronous programming languages are optimized for programming reactive systems, systems that are often interrupted and must respond quickly. Many such systems are also called realtime systems, and are used often in embedded systems. Examples: * Argus (programming language), Argus * Averest * Esterel * Lustre * SIGNAL (programming language), Signal * Céu (programming language)


Shading languages

A shading language is a graphics programming language adapted to programming shader effects. Such language forms usually consist of special data types, like "color" and "normal". Due to the variety of target markets for 3D computer graphics.


Real-time rendering

They provide both higher hardware abstraction and a more flexible programming model than previous paradigms which hardcoded transformation and shading equations. This gives the programmer greater control over the rendering process and delivers richer content at lower overhead. * Adobe Graphics Assembly Language (AGAL) * ARB assembly language (ARB assembly) * OpenGL Shading Language (GLSL or glslang) * High-Level Shading Language (HLSL) or DirectX Shader Assembly Language * PlayStation Shader Language (PSSL) * Metal (API), Metal Shading Language (MSL) * Cg (programming language), Cg * Shining Rock Shading Language (SRSL) * Spark * Nitrous Shading Language * Godot Shading Language


Offline rendering

Shading languages used in offline rendering produce maximum image quality. Processing such shaders is time-consuming. The computational power required can be expensive because of their ability to produce photorealistic results. * RenderMan Shading Language (RSL) * Houdini VEX Shading Language (VEX) * Gelato (software), Gelato Shading Language * Open Shading Language (OSL)


Syntax-handling languages

These languages assist with generating Lexical analysis, lexical analyzers and parsing, parsers for context-free grammars. * ANTLR * Coco/R (EBNF with semantics) * GNU bison (FSF's version of Yacc) * GNU Flex (lexical analyser generator), Flex (FSF version of Lex) * glex/gyacc (GoboSoft compiler-compiler to Eiffel) * lex (software), lex (Lexical Analysis, from Bell Labs) * M4 (computer language), M4 * Parsing expression grammar (PEG) * Prolog *

System languages

The system programming languages are for low-level tasks like memory management or task management. A system programming language usually refers to a programming language used for system programming; such languages are designed for writing system software, which usually requires different development approaches when compared with application software. System software is computer software designed to operate and control the computer hardware, and to provide a platform for running application software. System software includes software categories such as operating systems, utility software, device drivers, compilers, and linkers. Examples of system languages include:


Transformation languages

Transformation languages serve the purpose of transforming (translating) source code specified in a certain formal language into a defined destination format code. It is most commonly used in intermediate components of more complex super-systems in order to adopt internal results for input into a succeeding processing routine. * ATLAS Transformation Language, ATL * AWK * MOFM2T * QVT


Visual languages

Visual programming languages let users specify programs in a two-(or more)-dimensional way, instead of as one-dimensional text strings, via graphic layouts of various types. Some dataflow programming languages are also visual languages. * Analytica * Blockly * Clickteam, Clickteam Fusion * DRAKON * Fabrik (software), Fabrik * G (used in LabVIEW) * Grasshopper 3D, Grasshopper *
