Installing emacs on buster

so many ways to get software

Published March 5, 2021 #emacs, #debian, #flatpak

I've already written about installing emacs-snapshot on debian buster, here are two additional ways. The first is to use flatpak, and the other is to build from source.

Flatpack

sudo apt-get install flatpak
sudo apt install gnome-software-plugin-flatpak
sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Then:

sudo flatpak install flathub org.gnu.emacs

And running it:

flatpak run org.gnu.emacs

You can then pin it in your dock and you are good to go.

From Source

For buster debian, make sure you have the deb-src lines in your /etc/apt/sources.list

deb http://deb.debian.org/debian buster main contrib non-free
deb-src http://deb.debian.org/debian buster main contrib non-free

deb http://deb.debian.org/debian-security/ buster/updates main contrib non-free
deb-src http://deb.debian.org/debian-security/ buster/updates main contrib non-free

deb http://deb.debian.org/debian buster-updates main contrib non-free
deb-src http://deb.debian.org/debian buster-updates main contrib non-free

Then lets add the dependancies and pull down the emacs source code:

  sudo apt update

  # Make sure you have the builddeps

  sudo apt build-dep emacs25

  # Also install native json parsing

  sudo apt-get install libjansson4 libjansson-dev libmagickcore-dev

  # Download the monster
  git clone --depth 1 --branch emacs-27 https://git.savannah.gnu.org/git/emacs.git

Now we can run ./authgen.sh and ./configure:

  cd emacs
  ./autogen.sh
  ./configure
  make

You can test this out by running:

  src/emacs

Or just install it:

  sudo make install

.desktop file:

This is what I have in my ~/.local/share/applications/emacs.desktop:

[Desktop Entry]
Version=1.0
Name=Emacs 27
GenericName=Text Editor
Comment=View and edit files
MimeType=text/english;text/plain;text/x-makefile;text/x-c++hdr;text/x-c++src;text/x-chdr;text/x-csrc;text/x-java;text/x-moc;text/x-pascal;text/x-tcl;text/x-tex;application/x-shellscript;text/x-c;text/x-c++;
Exec=/usr/local/bin/emacs %F
TryExec=emacs
Icon=emacs
StartWMClass=emacs
Type=Application
Terminal=false
Categories=Utility;Development;TextEditor;

Native json support test

The whole point of this for me was to see if we have native json support. We can test this with:

(if (functionp 'json-serialize)
  (message "Native JSON is available")
(message "Native JSON is *not* available"))
Native JSON is available

More glorious language

A few years ago I read a great post about the value of a good dictionary, which I installed on my laptop and then promptly forgot about. The post is very moving, and I recommend checking it out. It was recently mentioned on the planet emacs blog circuit and so I thought I'd document how to get it up and running on my laptop. Also I don't understand what the appeal of John McPhee's writing, I've tried a few of his books but found them all so plodding.

Been playing with elfeed on Emacs 26.1 on buster and it keeps crashing. I think for font related reasons. So lets follow the Emacs Wiki Instructions to upgrade to emacs-snapshots and see if that helps. Add the snap shot repository. Make sure you have the tools installed so that apt can do it's internet thing. sudo apt-get install software-properties-common sudo apt-get update Add the signing key: wget -q http://emacs.

Rediscovering emacs

Intro I've been dipping back ito the world of free software, and have been having a huge amount of fun getting back into emacs. I'm using it more of an operating system than I ever did before, as a way to navigate the world using a text interface. I'd never thought I'd be done with the terminal, but this is the first time that I've got something better and more powerful.
