Popular Open Source IDEs for Developers

featured image for IDEs

It is feasible to develop apps without using integrated development environments (IDEs) or by manually integrating numerous utilities with a lightweight text editor such as Vim or Emacs. However, in an enterprise setting, the time savings, environment standardisation, and automation features of modern IDEs outweigh other issues. In this article, we will take a brief look at a few popular open source IDEs.

An integrated development environment (IDE) is an application development software incorporating standard developer tools into a single graphical user interface (GUI). An IDE is often made up of the following components.

A source code editor: This is a text editor that can help you write software code by highlighting syntax with visual cues, giving language-specific auto-completion, and checking for problems as you type.

Local build automation tools: These tools automate simple, recurring operations associated with making a local build of software for usage by developers, such as converting computer source code into binary code, packaging binary code, and performing automated tests.

A program that can graphically display the location of a bug in the original code and is used to test other applications.

Why do developers use integrated development environments (IDEs)?
Since different tools do not need to be manually configured and integrated as part of the setup process, an IDE allows developers to start programming new apps fast. When every utility is represented in the same workbench, developers no longer need to spend hours individually learning how to utilise different tools. This is also valuable for onboarding new engineers, who may use an IDE to learn about a team’s standard tools and workflows. In reality, most IDE capabilities, such as intelligent code completion and automatic code creation, are designed to save time by eliminating the need to write out whole character sequences.

Other popular IDE features are intended to assist developers in organising their workflow and problem-solving. IDEs parse code as it is written, identifying problems caused by a human mistake in real-time. Because a single graphical user interface represents utilities, developers can carry out activities without switching between apps. Most IDEs also include syntax highlighting, which employs visual clues to discern grammar in the text editor. Class and object browsers, and class hierarchy diagrams for specific languages are also included in several IDEs.

Today, most enterprise development teams choose a pre-configured IDE best suited to their specific use case. So the question is not whether to use an IDE, but which one to use.

The benefits of using an IDE
When writing a program, using an IDE will save you a lot of time and work. Among the benefits are:

  • Less time and effort: An IDE’s fundamental aim is to make development faster and easier. Its tools and features are designed to assist you in organising resources, avoiding mistakes, and providing shortcuts.
  • Enforce project or corporate standards: A group of programmers will adhere to a traditional manner of doing things just by working in the same development environment. Bars can be enforced further if the IDE provides predefined templates, or code libraries are shared across multiple team members/teams working on the same project.
  • Project management: This can be done in two ways. First, many IDEs provide documentation features that either automate developer comments or force developers to submit comments in various sections. Second, having a visual representation of resources should make it much easier to understand how an application is laid out rather than traversing the file system for hidden files in it.

Features of IDEs
There are several technical and business applications for IDEs, which means numerous proprietary and open source IDE solutions are already on the market. The essential distinguishing features amongst IDEs are listed below.

The number of languages supported: Some IDEs are dedicated to a single language and hence better suited to a specific programming paradigm. IntelliJ, for example, is best known as a Java IDE. Other IDEs, such as the Eclipse IDE, offer a wide range of languages in one package, such as Java, XML, Python, and others.

Operating system(s) supported: A developer’s operating system will limit which IDEs are viable (unless an IDE is cloud based). If the application created is intended for an end user with a particular operating system (such as Android or iOS), this may be an additional constraint.

Automation features: While most IDEs offer the three essential functions of a text editor, build automation, and debugger, many also enable refactoring, code search, and continuous integration and deployment (CI/CD) tools.

Impact on system performance: If a developer wants to run other memory-intensive apps concurrently, the memory footprint may be vital to consider.

Plugins and extensions: Some IDEs feature the ability to adapt workflows to meet needs and preferences.

The IDE is a very personal thing for programmers because they spend so much time with it. Furthermore, their performance is linked to the efficacy of the IDE they are using. The essential requirement of programmers is IDE software. Indeed, programmers have gained an advantage as a result of recent developments in IDE technology. Because the integrated development environment is specialised software that requires significant technical understanding and the sense to utilise it, firms frequently seek out programmers and coders who are well-versed and proficient in its use.

Artificial intelligence in IDEs is bringing about good changes in the way coding is done. Smart auto-suggestions and code completion tools have considerably reduced coding time. The introduction of numerous programming languages has presented coders with a plethora of possibilities for developing software. Simultaneously, it has created a demand for solid IDEs capable of working on different frameworks with multiple languages. Businesses that use IDEs instead of simple code editors for their programming needs save money. Companies should invest in integrated development environment software to meet their programming needs.

The best part? We have several IDEs available for Windows that are both free to use and fully open source.
