GNUstep
GNUstep is a free software implementation of the Cocoa (formerly OpenStep) Objective-C frameworks, widget toolkit, and application development tools for Unix-like operating systems and Microsoft Windows. It is part of the GNU Project. GNUstep features a cross-platform, object-oriented IDE. Apart from the default Objective-C interface, GNUstep also has bindings for Java, Ruby, GNU Guile and Scheme. The GNUstep developers track some additions to Apple's Cocoa to remain compatible. The roots of the GNUstep application interface are the same as the roots of Cocoa: NeXTSTEP and OpenStep. GNUstep thus predates Cocoa, which emerged when Apple acquired NeXT's technology and incorporated it into the development of the original Mac OS X, while GNUstep was initially an effort by GNU developers to replicate the technically ambitious NeXTSTEP's programmer-friendly features. History GNUstep began when Paul Kunz and others at Stanford Linear Accelerator Center wanted to port HippoDraw f ...

Objective-C
Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. Originally developed by Brad Cox and Tom Love in the early 1980s, it was selected by NeXT for its NeXTSTEP operating system. Due to Apple macOS’s direct lineage from NeXTSTEP, Objective-C was the standard programming language used, supported, and promoted by Apple for developing macOS and iOS applications (via their respective APIs, Cocoa and Cocoa Touch) until the introduction of the Swift programming language in 2014. Objective-C programs developed for non-Apple operating systems or that are not dependent on Apple's APIs may also be compiled for any platform supported by GNU GCC or LLVM/Clang. Objective-C source code 'messaging/implementation' program files usually have filename extensions, while Objective-C 'header/interface' files have extensions, the same as C header files. Objective-C++ files are denoted with a file extension. ...

Window Maker
Window Maker is a free and open-source window manager for the X Window System, allowing graphical applications to be run on Unix-like operating-systems. It is designed to emulate NeXTSTEP's GUI as an OpenStep-compatible environment. Window Maker is part of the GNU Project. Overview Window Maker has been characterized as reproducing "the elegant look and feel of the NeXTSTEP GUI" and is noted as "easy to configure and easy to use." A graphical tool called Wprefs is included and can be used to configure most aspects of the UI. The interface tends towards a minimalist, high performance environment directly supporting XPM, PNG, JPEG, TIFF, GIF and PPM icons with an alpha-channel and a right-click, sliding-scrolling application menu system which can throw off pinnable menus, along with window-icon miniaturization and other animations on multiple desktops. Menus and preferences can be changed without restarting. As with most window managers it supports themes and many are available. O ...

OpenStep
OpenStep is a defunct object-oriented application programming interface (API) specification for a legacy object-oriented operating system, with the basic goal of offering a NeXTSTEP-like environment on non-NeXTSTEP operating systems. OpenStep was principally developed by NeXT with Sun Microsystems, to allow advanced application development on Sun's operating systems, specifically Solaris (operating system), Solaris. NeXT produced a version of OpenStep for its own Mach kernel, Mach-based Unix, stylized as OPENSTEP, as well as a version for Windows NT. The software libraries that shipped with OPENSTEP are a superset of the original OpenStep specification, including many features from the original NeXTSTEP. History In the early era of the Sun Microsystems history, Sun machines had been programmed at a relatively low-level making calls directly to the underlying Unix operating system and producing a graphical user interface (GUI) using the X11 system. This led to complex programming ev ...

TextEdit
TextEdit is an open-source word processor and text editor, first featured in NeXT's NeXTSTEP and OPENSTEP. It is now distributed with macOS since Apple Inc.'s acquisition of NeXT, and available as a GNUstep application for other Unix-like operating systems such as Linux. It is powered by Apple Advanced Typography. Implementation TextEdit replaced the text editor of previous Macintosh operating systems, SimpleText. TextEdit uses the Cocoa text system to read and write documents in Rich Text Format (RTF), Rich Text Format Directory, plain text, and HTML formats, and can open (but not save) old SimpleText files. It also has access to the operating system's built-in spell-checking service. The version included in Mac OS X v10.3 added the ability to read and write documents in Word format, and the version in Mac OS X v10.4 added the ability to read and write Word XML documents. The version included in Mac OS X v10.5 added read and write support for Office Open XML and OpenDocum ...

NeXTSTEP
NeXTSTEP is a discontinued object-oriented, multitasking operating system based on the Mach kernel and the UNIX-derived BSD. It was developed by NeXT Computer in the late 1980s and early 1990s and was initially used for its range of proprietary workstation computers such as the NeXTcube. It was later ported to several other computer architectures. Although relatively unsuccessful at the time, it attracted interest from computer scientists and researchers. It hosted the original development of the Electronic AppWrapper, the first commercial electronic software distribution catalog to collectively manage encryption and provide digital rights for application software and digital media, a forerunner of the modern "app store" concept. It is the platform on which Tim Berners-Lee created the first web browser, and on which id Software developed the video games ''Doom'' and '' Quake''. In 1996, NeXT was acquired by Apple Computer to succeed the classic Mac OS, by merging NeXTSTEP ...

Paul Kunz
Paul Kunz (December 20, 1942 – September 12, 2018) was an American Particle physicist and software developer, who initiated the deployment of the first web server outside of Europe. After a meeting in September with Tim Berners-Lee of CERN, he returned to the Stanford Linear Accelerator Center with word of the World Wide Web. By Thursday, December 12, 1991 there was an active web server, SPIRES HEP in place thanks to the efforts of Kunz, Louise Addis, and Terry Hung. He was also the originator of the free/open source GNUstep implementation of the NeXTSTEP NeXTSTEP is a discontinued object-oriented, multitasking operating system based on the Mach kernel and the UNIX-derived BSD.

Language Binding
In programming and software design, binding is an application programming interface (API) that provides glue code specifically made to allow a programming language to use a foreign library or operating system service (one that is not native to that language). Characteristics Binding generally refers to a mapping of one thing to another. In the context of software libraries, bindings are wrapper libraries that bridge two programming languages, so that a library written for one language can be used in another language. Many software libraries are written in system programming languages such as C or C++. To use such libraries from another language, usually of higher-level, such as Java, Common Lisp, Scheme, Python, or Lua, a binding to the library must be created in that language, possibly requiring recompiling the language's code, depending on the amount of modification needed. However, most languages offer a foreign function interface, such as Python's and OCaml's ctypes, and ...

Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally developed ...

Ruby Programming Language
Ruby is an interpreted, high-level, general-purpose programming language which supports multiple programming paradigms. It was designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an object, including primitive data types. It was developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan. Ruby is dynamically typed and uses garbage collection and just-in-time compilation. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. According to the creator, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, BASIC, Java and Lisp. History Early concept Matsumoto has said that Ruby was conceived in 1993. In a 1999 post to the ''ruby-talk'' mailing list, he describes some of his early ideas about the language: Matsumoto describes the design of Ruby as being like a simple Lisp language at its core, with an object system like that of Smalltalk, blocks inspired by higher-order ...

GNU Guile
GNU Ubiquitous Intelligent Language for Extensions (GNU Guile) is the preferred extension language system for the GNU Project and features an implementation of the programming language Scheme. Its first version was released in 1993. In addition to large parts of Scheme standards, Guile Scheme includes modularized extensions for many different programming tasks. For extending programs, Guile offers ''libguile'' which allows the language to be embedded in other programs, and integrated closely through the C language application programming interface (API); similarly, new data types and subroutines defined through the C API can be made available as extensions to Guile. Guile is used in programs such as GnuCash, LilyPond, GNU Guix, GNU Debugger, GNU TeXmacs anGoogle's schism Guile Scheme Guile Scheme is a general-purpose, high-level programming language whose flexibility allows expressing concepts in fewer lines of code than would be possible in languages such as C.
