- emacs@conference.conversations.im for Emacs peer support including jabber.el

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://codeberg.org/emacs-jabber/emacs-jabber.git"
            :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 codeberg
              :repo "emacs-jabber/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. 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://codeberg.org/emacs-jabber/emacs-jabber/issues/%s")
        ("#guix%irc\\.libera.chat@irc\\.biboumi-gateway\\.example"
         "\\(#\\([0-9]+\\)\\)"
         "https://codeberg.org/guix/guix/issues/%s")))

5. Basic commands

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