Integrated development environment
This page is a soft redirect.IDE]].
An integrated development environment (IDE) or interactive development environment is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. Most modern IDEs have intelligent code completion.
Some IDEs contain a compiler, interpreter, or both, such as NetBeans and Eclipse; others do not, such as SharpDevelop and Lazarus. 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 Graphical User Interface (GUI). Many modern IDEs also have a class browser, an object browser, and a class hierarchy diagram, for use in object-oriented software development.
Integrated development environments are designed to maximize programmer productivity by providing tight-knit components with similar user interfaces. IDEs present a single program in which all development is done. This program typically provides many features for authoring, modifying, compiling, deploying and debugging software. This contrasts with software development using unrelated tools, such as vi, GCC or make.
One aim of the IDE is to reduce the configuration necessary to piece together multiple development utilities, instead providing the same set of capabilities as a cohesive unit. Reducing that setup time can increase developer productivity, in cases where learning to use the IDE is faster than manually integrating all of the individual tools. Tighter integration of all development tasks has the potential to improve overall productivity beyond just helping with setup tasks. For example, code can be continuously parsed while it is being edited, providing instant feedback when syntax errors are introduced. That can speed learning a new programming language and its associated libraries.
Some IDEs are dedicated to a specific programming language, allowing a feature set that most closely matches the programming paradigms of the language. However, there are many multiple-language IDEs, such as Eclipse, ActiveState Komodo, IntelliJ IDEA, MyEclipse, Oracle JDeveloper, NetBeans, Codenvy and Microsoft Visual Studio. Xcode, Xojo and Delphi are dedicated to a closed language or set of programming languages.
While most modern IDEs are graphical, text-based IDEs such as Turbo Pascal were in popular use before the widespread availability of windowing systems like Microsoft Windows and the X Window System (X11). They commonly use function keys or hotkeys to execute frequently used commands or macros.
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 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.
Support for alternative languages is often provided by plugins, allowing them to be installed on the same IDE at the same time. For example, Flycheck is a modern on-the-fly syntax checking extension for GNU Emacs 24 with support for 39 languages. Eclipse, and Netbeans have plugins for C/C++, Ada, GNAT (for example AdaGIDE), Perl, Python, Ruby, and PHP, which are selected between automatically based on file extension, environment or project settings.
Attitudes across different computing platforms
Unix programmers can combine command-line POSIX tools into a complete development environment, capable of developing large programs such as the Linux kernel and its environment. The free software GNU tools (GNU Compiler Collection (GCC), GNU Debugger (gdb), and GNU make) are available on many platforms, including Windows. Developers who favor command-line oriented tools can use editors with support for many of the standard Unix and GNU build tools, building an IDE with programs like Emacs or Vim. Data Display Debugger is intended to be an advanced graphical front-end for many text-based debugger standard tools. Some programmers prefer managing makefiles and their derivatives to the similar code building tools included in a full IDE. For example, most contributors to the PostgreSQL database use make and gdb directly to develop new features. Even when building PostgreSQL for Microsoft Windows using Visual C++, Perl scripts are used as a replacement for make rather than relying on any IDE features. Some Linux IDEs such as Geany attempt to provide a graphical front end to traditional build operations.
On the various Microsoft Windows platforms, command-line tools for development are seldom used. Accordingly, there are many commercial and non-commercial products. 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, .NET Framework SDK, nmake utility), Embarcadero Technologies (bcc32 compiler, make utility).
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 of the mid-1980s. Currently Mac OS X programmers can choose between native IDEs like Xcode and open-source tools such as Eclipse and Netbeans. ActiveState Komodo is a proprietary multilanguage IDE supported on the Mac OS.
