Full description

1. About

jabber.svg

jabber.el is an XMPP client for Emacs.

See the xmpp.org page for the full list of supported XEPs.

2. Requirements

  • Emacs 29.1 or later, compiled with dynamic module support

2.1. OMEMO encryption (optional)

OMEMO end-to-end encryption requires building a native C module. You need a C compiler, pkg-config, and libmbedtls (the development headers). On first load, Emacs will prompt to build the module automatically.

3. Installation

jabber.el is available via NonGNU ELPA.

You can install it via M-x package-install RET jabber

3.1. package-vc (Emacs 30+)

(use-package jabber
  :ensure nil
  :vc (:url "https://git.thanosapollo.org/emacs-jabber/"
            :branch "master"
            :rev :newest
            :lisp-dir "lisp")
  :custom
  (jabber-account-list '(("user@example.org")))
  :config
  (jabber-modeline-mode 1)
  :bind-keymap (("C-x C-j" . jabber-global-keymap))
  :hook (kill-emacs . jabber-disconnect))

3.2. From source

git clone https://git.thanosapollo.org/emacs-jabber/
cd emacs-jabber
make module   # optional, for OMEMO support

Then add to your init file: 

(add-to-list 'load-path "/path/to/emacs-jabber/lisp")
(require 'jabber)

4. Configuration

Accounts are configured via jabber-account-list. The simplest form uses auth-source ~/.authinfo.gpg for passwords: 

(setq jabber-account-list '(("user@example.org")
                             ("second@account.org")))

With pass (password-store): 

(setq jabber-account-list
      `(("user@example.org"
         (:password . ,(auth-source-pass-get 'secret "xmpp/example.org/user")))))

5. Basic commands

Key Command
M-x jabber-connect Connect (prompts for account)
C-x C-j C-c Connect all accounts
C-x C-j C-d Disconnect
C-x C-j C-r Open roster buffer
C-x C-j C-j Start or switch to a chat
C-x C-j C-m Join/switch to a MUC (groupchat)
C-x C-j C-b Switch to a chat buffer
