Atom is an open-source, configurable yet beginner-friendly text editor developed by GitHub. It is built using web technologies on top of the Electron framework.
Installation
Its development team provides Debian, RPM and tar (file extension: .tar.gz) binaries for 64-bit Linux, but not for 32-bit systems. There are three main ways of installing Atom:
1. Using official binary releases from the Atom development team (suitable for 64-bit systems only).
2. Using the unofficial mosquito/atom Copr (for 32-bit and 64-bit systems).
3. By manually compiling its source code and installing the resulting RPM.
The fastest of these methods is probably #1. This option does not have auto-updating, however, so when new releases of Atom come out in order to upgrade you will have to manually re-download and install the RPMs of these newer releases. Option 2 is fairly fast too, but the Copr does tend to lag a couple of days behind the latest Atom release. Despite this the Copr option does have auto-updating.
Official binaries
To install Atom from the official RPM package provide by the Atom team (which is only suitable for 64-bit systems!) for the latest stable (as opposed to beta releases which are also packaged at RPMs) Atom release, run:
$ sudo dnf install $(wget -q "https://api.github.com/repos/atom/atom/releases/latest" -O - | grep "https.*atom.x86_64.rpm" | cut -d '"' -f 4)
While there is no official way to auto-update these binaries here is a ~/.bashrc (also compatible with the Zsh shell's ~/.zshrc file) snippet that will automatically check for available Atom updates and install them whenever one opens a terminal:
ATOM_INSTALLED_VERSION=$(rpm -qi atom | grep "Version" | cut -d ':' -f 2 | cut -d ' ' -f 2)
ATOM_LATEST_VERSION=$(wget -q "https://api.github.com/repos/atom/atom/releases/latest" -O - | grep -E "https.*atom-amd64.tar.gz" | cut -d '"' -f 4 | cut -d '/' -f 8 | sed 's/v//g')
if [[ $ATOM_INSTALLED_VERSION < $ATOM_LATEST_VERSION ]]; then
sudo dnf install -y https://github.com/atom/atom/releases/download/v${ATOM_LATEST_VERSION}/atom.x86_64.rpm
fi
Copr
To install Atom from the mosquito/atom Copr run:
$ sudo dnf copr enable mosquito/atom $ sudo dnf install atom
Building from source
There is an official guide to installing Atom from source code on Linux.
