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
  • fsm 0.2.0 or later
  • keymap-popup 0.2 or later

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 from the ELPA package directory: 

cd /path/to/elpa/jabber-VERSION
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. That is the only supported install path. 

(use-package jabber
  :ensure t
  :config
  (setq jabber-account-list
        `(("user@example.org"
           (:password . ,(auth-source-pass-get 'secret "xmpp/example.org")))))
  (jabber-modeline-mode 1)
  :bind-keymap (("C-x C-j" . jabber-global-keymap))
  :hook (kill-emacs . jabber-disconnect))

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")))

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.

  • XEP-0201 message threads with persistent sessions, local titles, child threads, and account-scoped routing
  • XEP-0004 forms for MUC configuration and ad-hoc commands
  • Unauthenticated SOCKS5 account :proxy support; destination names are resolved by the proxy, and authentication and other proxy protocols are not supported
