Atom 1.0 has a stable API (application programming interface), allowing outside developers to build additional packages for the software without worrying whether the API calls will change in a future edition.
"They can build on this API," Ben Ogle, a GitHub developer who is one of the core contributors to Atom said. "Version 1.0 is the foundation for the future. We're not just trying to build a product. The goal is to build a community around Atom," he added.
Since the beta launch a year ago, the editor has gotten a number of new features, such as support for resizable windows and the ability to work with multiple folders, Ogle said. Performance improvements were also made to make it run more quickly. Third-party packages can now communicate with one another.
Many developers have long eschewed full-featured IDEs (integrated development environments) such as Eclipse and Visual Studio in favor of smaller and more customizable text editors.
The two most widely used command-line text editors, Emacs and Vi, have been available for decades. As a result, outside contributors have added a lot of functionality to them, making them useful for composing programs, scripts and other text-based projects.
Like Emacs and Vi, Atom is open source and can be extended to fit specific programming languages. It can also be customized to the programmer's tastes. "Your dream editor is probably different than my dream editor. You can mold Atom into anything you want," Ogle said.
The development team kept the core Atom package as slim as possible, shifting much of the functionality to stand-alone add-on packages that can be easily installed through the use of a package manager. Atom is built on a framework that utilizes the Google Chromium shell.
