Install GNU Emacs on Ubuntu Linux. GNU Emacs is an extensible, customizable, free/libre text editor — and more. At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing.

Features of GNU Emacs:

  • Content-aware editing modes, including syntax coloring, for many file types.
  • Complete built-in documentation, including a tutorial for new users.
  • Full Unicode support for nearly all human scripts.
  • Highly customizable, using Emacs Lisp code or a graphical interface.
  • An entire ecosystem of functionality beyond text editing, including a project planner, mail and news reader, debugger interface, calendar, and more.

The emacs26 PPA description states that “This emacs26 repository contains updated emacs packages based on stable releases. The following package series are available: emacs26: based on 26.x-series releases and emacs25: based on 25.x-series releases. The emacs26 packages have mailutils and systemd support (the two build-time options that are new in emacs26) enabled. The emacs26 packages for 14.04 have failed to build because not all of the dependencies that are required to enable these options are available. The emacs26 packages have xwidgets support. The emacs25 packages do not. If you are interested in xwidgets support in emacs25, please send me a note; it would not be hard to update those packages.”

Emacs 26.1 has a wide variety of new features, including:

  • Limited form of concurrency with Lisp threads
  • Support for optional display of line numbers in the buffer
  • Emacs now uses double buffering to reduce flicker on the X Window System
  • Flymake has been completely redesigned
  • TRAMP has a new connection method for Google Drive
  • New single-line horizontal scrolling mode
  • A systemd user unit file is provided
  • Support for 24-bit colors on capable text terminals
