wxHaskell is a portable and native graphical user interface (GUI) library for the programming language Haskell, built on wxWidgets. It is often used by those wanting to develop a GUI with a functional programming language. [1]
wxHaskell is a middle-level GUI library. [2] Several experimental high-level GUI library approaches are implemented on wxHaskell:
In contrast, the high-level GUI libraries FG and Grapefruit are implemented on the middle-level Gtk2Hs, which is based on GTK2.
All of these high-level libraries are experimental, using advanced mathematics concepts in their approach (see arrows in functional programming ).
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit. Proficient programming usually requires expertise in several different subjects, including knowledge of the application domain, details of programming languages and generic code libraries, specialized algorithms, and formal logic.
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 that map values to other values, rather than a sequence of imperative statements which update the running state of the program.
In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.
wxWidgets is a widget toolkit and tools library for creating graphical user interfaces (GUIs) for cross-platform applications. wxWidgets enables a program's GUI code to compile and run on several computer platforms with no significant code changes. A wide choice of compilers and other tools to use with wxWidgets facilitates development of sophisticated applications. wxWidgets supports a comprehensive range of popular operating systems and graphical libraries, both proprietary and free.
Curry is a declarative programming language, an implementation of the functional logic programming paradigm, and based on the Haskell language. It merges elements of functional and logic programming, including constraint programming integration.
The Standard Widget Toolkit (SWT) is a graphical widget toolkit for use with the Java platform. It was originally developed by Stephen Northover at IBM and is now maintained by the Eclipse Foundation in tandem with the Eclipse IDE. It is an alternative to the Abstract Window Toolkit (AWT) and Swing Java graphical user interface (GUI) toolkits provided by Sun Microsystems as part of the Java Platform, Standard Edition (J2SE).
NESL is a parallel programming language developed at Carnegie Mellon by the SCandAL project and released in 1993. It integrates various ideas from parallel algorithms, functional programming, and array programming languages.
C-- is a C-like programming language, designed to be generated mainly by compilers for high-level languages rather than written by human programmers. It was created by functional programming researchers Simon Peyton Jones and Norman Ramsey. Unlike many other intermediate languages, it is represented in plain ASCII text, not bytecode or another binary format.
GLib is a bundle of three low-level system libraries written in C and developed mainly by GNOME. GLib's code was separated from GTK, so it can be used by software other than GNOME and has been developed in parallel ever since.
The Apache Portable Runtime (APR) is a supporting library for the Apache web server. It provides a set of APIs that map to the underlying operating system (OS). Where the OS does not support a particular function, APR will provide an emulation. Thus programmers can use the APR to make a program truly portable across platforms.
Racket is a general-purpose, multi-paradigm programming language. The Racket language is a modern dialect of Lisp and a descendant of Scheme. It is designed as a platform for programming language design and implementation. In addition to the core Racket language, Racket is also used to refer to the family of programming languages and set of tools supporting development on and with Racket. Racket is also used for scripting, computer science education, and research.
FAUST is a domain-specific purely functional programming language for implementing signal processing algorithms in the form of libraries, audio plug-ins, or standalone applications. A FAUST program denotes a signal processor: a mathematical function that is applied to some input signal and then fed out.
A PIGUI package is a software library that a programmer uses to produce GUI code for multiple computer platforms. The package presents subroutines and/or objects which are independent of the GUIs that the programmer is targeting. For software to qualify as PIGUI it must support several GUIs under at least two different operating systems. The package does not necessarily provide any additional portability features. Native look and feel is a desirable feature, but is not essential for PIGUIs.
Functional reactive programming (FRP) is a programming paradigm for reactive programming using the building blocks of functional programming. FRP has been used for programming graphical user interfaces (GUIs), robotics, games, and music, aiming to simplify these problems by explicitly modeling time.
Olex and Olex2 are versatile software for crystallographic research. Olex used to be a research project developed during PhD to implement topological analysis of polymeric chemical structures and still is widely used around the world. Olex2 is an open source project with the C++ code portable to Windows, Mac and Linux. Although the projects share the common name they are not related at the source code level.
Haskell is a general-purpose, statically-typed, purely functional programming language with type inference and lazy evaluation. Designed for teaching, research, and industrial applications, Haskell has pioneered several programming language features such as type classes, which enable type-safe operator overloading, and monadic input/output (IO). It is named after logician Haskell Curry. Haskell's main implementation is the Glasgow Haskell Compiler (GHC).
Racket has been under active development as a vehicle for programming language research since the mid-1990s, and has accumulated many features over the years. This article describes and demonstrates some of these features. Note that one of Racket's main design goals is to accommodate creating new programming languages, both domain-specific languages and completely new languages. Therefore, some of the following examples are in different languages, but they are all implemented in Racket. Please refer to the main article for more information.
Red is a programming language designed to overcome the limitations of the programming language Rebol. Red was introduced in 2011 by Nenad Rakočević, and is both an imperative and functional programming language. Its syntax and general usage overlaps that of the interpreted Rebol language.
