Development Languages, Environments, and Tools

Free software development environments have different purposes: educational, developmental, educational, and the like. Their students can be schoolchildren, students, novice programmers.

Scientists propose the following classification of free software development environments:

• Environments that support one programming language;
• Environments with support for multiple programming languages;
• Development environments for web systems and applications;
• Environments aimed at a children's audience.

Of the free environments focused on a single programming language, the following tools should be highlighted: Lazarus, PyScripter, DrPython, Wing IDE.

Among the free software development tools designed for several programming languages, the following should be noted: CodeLite, Dev-C, Anjuta, Eric, Eclipse, HiAsm, Kylix, MonoDevelop, NetBeans, SharpDevelop, Xcode, etc.

From the list of free environments for creating web applications, you can select the following: AJAX.OOP, MooTools Code :: Blocks, Codelobster PHP Edition, Geany, Ultimate, Symfony, Grails. With their help, experts also produce the creation of websites and Internet interfaces.

Among the development tools intended for children's audiences, the following environments can be singled out: Algo, Alice, EToys, Scratch, Squeak, etc. The main purpose of their use is to encourage children to learn to program.

An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools, and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not.

The boundary between an IDE and other parts of the broader software development environment is not well-defined; sometimes a version control system or various tools to simplify the construction of a graphical user interface (GUI) are integrated. 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 it provides the same set of capabilities as one cohesive unit. Reducing setup time can increase developer productivity, especially in cases where learning to use the IDE is faster than manually integrating and learning 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. Allowing developers to debug code much faster and easier with an IDE.

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.

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.
