 Ement.el is a new Matrix client for Emacs.  It's basic at the moment, but it can be used to send and read messages (including replies and images), join and leave rooms, etc.

+The default formatting style resembles IRC clients, with each message being prefixed by the username (which enables powerful Emacs features, like using Occur to show all messages from or mentioning a user).  Alternative, built-in styles include an Element-like one with usernames above groups of messages, as well as a classic, no-margins IRC style.  Messages may be optionally displayed with unique colors for each user (with customizeable contrast), making it easier to follow conversations.  Timestamp headers are optionally displayed where a certain amount of time passes between events, as well as where the date changes.
