Unicon is a programming language designed by American computer scientist Clint Jeffery with collaborators including Shamim Mohamed, Jafar Al Gharaibeh, Robert Parlett and others. Unicon descended from Icon and a preprocessor for Icon called IDOL. Compared with Icon, Unicon offers better access to the operating system as well as support for object-oriented programming. Unicon began life as a merger of three popular Icon extensions: an OO preprocessor named Idol, a POSIX filesystem and networking interface, and an ODBC facility. The name is shorthand for "Unified Extended Dialect of Icon."

Features

Compared with Icon, many of the new features of Unicon are extensions to the I/O and system interface, to complement Icon's core control and data structures. Rather than providing lower-level APIs as-is from C, Unicon implements higher level and easier to use facilities, enabling rapid development of graphic- and network-intensive applications in addition to Icon's core strengths in text and file processing.

Feature list

When run as a graphical IDE, the Unicon program ui.exe continues to offer links to Icon help.

The official Unicon programming book in PDF format [5] is a popular way to learn Unicon. The book includes an introduction to object-oriented development as well as UML. It includes useful chapters on topics such as the use of Unicon for CGI. Recent additions to Unicon include true concurrency.

Unicode

Unicon is not yet Unicode-compliant. There are opportunities posted at a help-wanted page. [6]

Example code

proceduremain()w:=open("test UNICON window","g")write(w,"Hello, World!")read(w)close(w)end

The Portable Operating System Interface is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. POSIX defines both the system and user-level application programming interfaces (APIs), along with command line shells and utility interfaces, for software compatibility (portability) with variants of Unix and other operating systems. POSIX is also a trademark of the IEEE. POSIX is intended to be used by both application and system developers.

Rebol is a cross-platform data exchange language and a multi-paradigm dynamic programming language designed by Carl Sassenrath for network communications and distributed computing. It introduces the concept of dialecting: small, optimized, domain-specific languages for code and data, which is also the most notable property of the language according to its designer Carl Sassenrath:

Although it can be used for programming, writing functions, and performing processes, its greatest strength is the ability to easily create domain-specific languages or dialects

Allegro is a software library for video game development. The functionality of the library includes support for basic 2D graphics, image manipulation, text output, audio output, MIDI music, input and timers, as well as additional routines for fixed-point and floating-point matrix arithmetic, Unicode strings, file system access, file manipulation, data files, and 3D graphics. The library is written in the C programming language and designed to be used with C, C++, or Objective-C, with bindings available for Python, Lua, Scheme, D, Go, and other languages. Allegro comes with extensive documentation and many examples.

In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. In many cases, a thread is a component of a process.

Originally, the word computing was synonymous with counting and calculating, and the science and technology of mathematical calculations. Today, "computing" means using computers and other computing machines. It includes their operation and usage, the electrical processes carried out within the computing hardware itself, and the theoretical concepts governing them.

Programming languages can be grouped by the number and types of paradigms supported.

In computing, a visual programming language or block coding is a programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. For example, many VPLs are based on the idea of "boxes and arrows", where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations.

Windows Presentation Foundation (WPF) is a free and open-source graphical subsystem originally developed by Microsoft for rendering user interfaces in Windows-based applications. WPF, previously known as "Avalon", was initially released as part of .NET Framework 3.0 in 2006. WPF uses DirectX and attempts to provide a consistent programming model for building applications. It separates the user interface from business logic, and resembles similar XML-oriented object models, such as those implemented in XUL and SVG.

AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola 68000 series of 16-bit and 32-bit microprocessors. Later versions were developed by Haage & Partner and then Hyperion Entertainment. A PowerPC microprocessor is required for the most recent release, AmigaOS 4.

<span class="mw-page-title-main">API</span> Software interface between computer programs

An application programming interface (API) is a way for two or more computer programs or components to communicate with each other. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build or use such a connection or interface is called an API specification. A computer system that meets this standard is said to implement or expose an API. The term API may refer either to the specification or to the implementation. Whereas a system's user interface dictates how its end-users interact with the system in question, its API dictates how to write code that takes advantage of that system's capabilities.
