Description
Atom was an open source "hackable" code editor introduced in 2011 and sunset in December 2022. It ran on Mac, Windows and Linux and was free to use. Like the other free general purpose editors, it was not as full featured as paid tools such as Oxygen, and it required more set up effort on the part of the user. However, it could form part of a completely open tool chain and was well integrated with GitHub. Features could be added from a large library of add-on packages, such as support for XML highlighting, completion and validation.

From the Atom web page:
 * Cross-platform editing. Atom works across operating systems. Use it on OS X, Windows, or Linux.
 * Built-in package manager. Search for and install new packages or create your own right from Atom.
 * Smart autocompletion. Atom helps you write code faster with a smart and flexible autocomplete.
 * File system browser. Easily browse and open a single file, a whole project, or multiple projects in one window.
 * Multiple panes. Split your Atom interface into multiple panes to compare and edit code across files.
 * Find and replace. Find, preview, and replace text as you type in a file or across all your projects
