Sign.el

Sign.el is an Emacs interface for Signal. It communicates with a running signal-cli daemon via JSON-RPC to send and receive messages.

Features

• Chat Buffers: Read-only history with a guarded input prompt.
• Media Support: Renders inline images and attachments.
• Animated Stickers: Automatically converts APNG and WebP stickers to GIF for playback in Emacs.
• Dashboard: Overview of active conversations.
• Notifications: Native desktop notifications on new messages.

Dependencies

1. Emacs 27.1+
2. signal-cli: Must be installed and available in your $PATH.
3. ImageMagick (Optional): The convert command is required to render animated stickers.
