To install Emacs in Ubuntu 17.04
Emacs is an extensible, customizable, self-documenting, real-time display editor. Emacs runs on several operating systems. Emacs and its derivatives are a family of text editors that are characterized by their extensibility. Emacs Lisp gives an extension capability allowing users and developers to write new commands using a dialect of the Lisp programming language with different " modes" , enabling it to be used like an Integrated Development Environment (IDE) for programming languages like Java, C or Python. It contains features such as Content-aware editing modes, Complete built-in documentation, Highly customizable, using Emacs Lisp code or a graphical interface. This tutorial explains the installation procedure of Emacs in Ubuntu 17.04.
Installation procedure
To begin with the installation procedure, add the repository for the Emacs and run the following command.
root@linuxhelp:~# add-apt-repository ppa:kelleyk/emacs
This repository contains updated `emacs` packages based on stable releases.
The following package series are available:
- `emacs25`: based on 25.x-series releases.
On top of each series, I have applied the following patches:
- A fix for an `xinput`-related bug that, when triggered, causes `emacs` to enter an infinite loop the process will then be unresponsive and will consume 100% of a single CPU core until you kill it.
Debug symbols are available! After adding the PPA however you normally do, find the corresponding entry in `/etc/apt/sources.list.d`.
It will look like the first line below (though the suite name may be different if you are not using xenial) duplicate it and change the component name (" main" ) to " main/debug" .
