An integrated development environment (IDE) (also known as integrated design environment, integrated debugging environment or interactive development environment) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of:
The boundary between an integrated development environment and other parts of the broader software development environment is not well-defined. Sometimes a version control system and various tools are integrated to simplify the construction of a GUI. Many modern IDEs also have a class browser, an object inspector, and a class hierarchy diagram, for use with object-oriented software development.[1]

IDEs are designed to maximize programmer productivity by providing tightly-knit components with similar user interfaces. This should mean that the programmer has to do less mode switching versus using discrete development programs. However, because an IDE is a complicated piece of software by its very nature, this higher productivity only occurs after a lengthy learning process.
Typically an IDE is dedicated to a specific programming language, allowing a feature set that most closely matches the programming paradigms of the language. However, there are some multiple-language IDEs, such as Eclipse, ActiveState Komodo, IntelliJ IDEA, Oracle JDeveloper, recent versions of NetBeans, Microsoft Visual Studio, Genuitec MyEclipse, WinDev, and Xcode.
IDEs typically present a single program in which all development is done. This program typically provides many features for authoring, modifying, compiling, deploying and debugging software. The aim is to abstract the configuration necessary to piece together command line utilities in a cohesive unit, which theoretically reduces the time to learn a language, and increases developer productivity. It is also thought that the tight integration of development tasks can further increase productivity. For example, code can be parsed while being written, providing instant feedback on syntax errors. While most modern IDEs are graphical, IDEs in use before the advent of windowing systems (such as Microsoft Windows or X11) were text-based, using function keys or hotkeys to perform various tasks (Turbo Pascal is a common example). This contrasts with software development using unrelated tools, such as vi, GCC or make.
IDEs initially became possible when developing via a console or terminal. Early systems could not support one, since programs were prepared using flowcharts, entering programs with punched cards (or paper tape, etc.) before submitting them to a compiler. Dartmouth BASIC was the first language to be created with an IDE (and was also the first to be designed for use while sitting in front of a console or terminal). Its IDE (part of the Dartmouth Time Sharing System) was command-based, and therefore did not look much like the menu-driven, graphical IDEs prevalent today. However it integrated editing, file management, compilation, debugging and execution in a manner consistent with a modern IDE.
Maestro I is a product from Softlab Munich and was the world's first integrated development environment[3] 1975 for software. Maestro I was installed for 22,000 programmers worldwide. Until 1989, 6,000 installations existed in the Federal Republic of Germany. Maestro I was arguably the world leader in this field during the 1970s and 1980s. Today one of the last Maestro I can be found in the Museum of Information Technology at Arlington.
One of the first IDEs with a plug-in concept was Softbench. In 1995 Computerwoche commented that the use of an IDE was not well received by developers since it would fence in their creativity.
Visual programming is a usage scenario in which an IDE is generally required. Visual IDEs allow users to create new applications by moving programming, building blocks, or code nodes to create flowcharts or structure diagrams that are then compiled or interpreted. These flowcharts often are based on the Unified Modeling Language.
This interface has been popularized with the Lego Mindstorms system, and is being actively pursued by a number of companies wishing to capitalize on the power of custom browsers like those found at Mozilla. KTechlab supports flowcode and is a popular opensource IDE and Simulator for developing software for microcontrollers. Visual programming is also responsible for the power of distributed programming (cf. LabVIEW and EICASLAB software). An early visual programming system, Max, was modelled after analog synthesizer design and has been used to develop real-time music performance software since the 1980s. Another early example was Prograph, a dataflow-based system originally developed for the Macintosh. The graphical programming environment "Grape" is used to program qfix robot kits.
This approach is also used in specialist software such as Openlab, where the end users want the flexibility of a full programming language, without the traditional learning curve associated with one.
An open source visual programming system is Mindscript, which has extended functionality for cryptology, database interfacing,
Some IDEs support multiple languages, such as Eclipse, IntelliJ IDEA, MyEclipse or NetBeans, all based on Java, or MonoDevelop, based on C#.
Support for alternative languages is often provided by plugins, allowing them to be installed on the same IDE at the same time. For example, Eclipse and Netbeans have plugins for C/C++, Ada, GNAT (for example AdaGIDE), Perl, Python, Ruby, and PHP, among other languages in use.
Many Unix programmers argue that traditional command-line POSIX tools constitute a complete development environment,[4] an IDE, though one with a different style of interface and under the Unix environment. Many programmers still use makefiles and their derivatives. Also, many Unix programmers use Emacs[5][6][7] or Vim, which integrate support for many of the standard Unix build tools. Data Display Debugger is intended to be an advanced graphical front-end for many text-based debugger standard tools.
On the various Microsoft Windows platforms, command-line tools for development are seldom used. Accordingly, there are many commercial and non-commercial solutions, however each has a different design commonly creating incompatibilities. Most major compiler vendors for Windows still provide free copies of their command-line tools, including Microsoft (Visual C++, Platform SDK, Microsoft .NET Framework SDK, nmake utility), Embarcadero Technologies (bcc32 compiler, make utility).
Additionally, the free software GNU tools (gcc, gdb, GNU make) are available on many platforms, including Windows[8] etc.
IDEs have always been popular on the Apple Macintosh's Mac OS, dating back to Macintosh Programmer's Workshop, Turbo Pascal, THINK Pascal and THINK C environments in the mid-1980s. Currently Mac OS X programmers can choose between limited IDEs, including native IDEs like Xcode, older IDEs like CodeWarrior, newer IDEs like MyEclipse, and open-source tools, such as Eclipse and Netbeans. ActiveState Komodo is a proprietary IDE supported on the Mac OS.
