A hackable text editor for the 21st Century

Snippet from Wikipedia: Atom (text editor)

Atom is a free and open-source text and source code editor for macOS, Linux, and Microsoft Windows with support for plug-ins written in JavaScript, and embedded Git Control. Developed by GitHub, Atom is a desktop application built using web technologies. Most of the extending packages have free software licenses and are community-built and maintained. Atom is based on Electron (formerly known as Atom Shell), a framework that enables cross-platform desktop applications using Chromium and Node.js. Atom is written in CoffeeScript and Less, but much of it has been converted to JavaScript.

Atom was released from beta, as version 1.0, on 25 June 2015. Its developers call it a "hackable text editor for the 21st Century", as it is fully customizable in HTML, CSS, and JavaScript.
