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 uses a native C module built from the vendored picomemo source. Build dependencies: a C compiler, pkg-config, and Mbed TLS 3.0 or later (mbedcrypto).

Build the module manually from the jabber source or ELPA/package directory: 

cd /path/to/jabber-source-or-elpa-dir
make module

The resulting jabber-omemo-core.so (or .dylib on macOS) lands beside the Elisp files and is loaded automatically. If the module is missing, OMEMO use signals OMEMO module not compiled.

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+)

Emacs honors package-vc build commands such as :make only when package-vc-allow-build-commands allows the package. 

(setq package-vc-allow-build-commands '(jabber))

(use-package jabber
  :ensure nil
  :vc (:url "https://git.thanosapollo.org/emacs-jabber"
            :branch "master"
            :rev :newest
            :lisp-dir "lisp"
            :doc "README.org"
            :make "module")
  :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. straight.el

(use-package jabber
  :straight `(jabber
              :type git
              :host nil
              :repo "https://git.thanosapollo.org/emacs-jabber"
              :branch "master"
              :files ("lisp/*.el"
                      "lisp/jabber-omemo-core.so"
                      "lisp/jabber-omemo-core.dylib")
              :pre-build ,(pcase system-type
                            ('berkeley-unix '(("gmake" "module" "CC=clang")))
                            ('darwin '(("make" "module" "CC=clang")))
                            (_ '(("make" "module")))))
  :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))

3.3. Nix

The repository ships a flake.nix with Emacs, test, lint, and native-module build dependencies. 

make test
make module

To enter the same environment manually: 

nix develop

To run the isolated Nix checks: 

nix flake check

4. Configuration

4.1. Authentication

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")))))

4.2. SOCKS5 proxy

An account can connect through an unauthenticated SOCKS5 proxy: 

(setq jabber-account-list
      '(("user@example.org"
         (:proxy . (:type socks5 :host "127.0.0.1" :port 9050)))))

The destination hostname is sent to the proxy rather than resolved locally. Proxy connections bypass SRV lookup and use the JID domain on port 5222, or :network-server and :port when those are configured. STARTTLS is supported. Direct TLS discovery, proxy authentication, and other proxy protocols are not supported for proxied accounts.

4.3. Bug references

(add-hook 'jabber-chat-mode-hook #'bug-reference-mode)

;; Customize references
(setq jabber-bug-reference-alist
      '(("jabber-el@conference\\.hmm\\.st"
         "\\(#\\([0-9]+\\)\\)"
         "https://todos.thanosapollo.org/r/emacs-jabber/%s")))

5. Basic commands

  • Use M-x jabber-roster or C-x C-j C-r to get started.
