hive-emacs

Emacs vessel addon for hive-mcp — implements IVessel / IEditor for Emacs.

What it does

hive-emacs extracts all Emacs-specific code from hive-mcp core into a standalone IAddon project:

• IEditor via EmacsclientEditor — emacsclient subprocess with circuit breaker and daemon death detection
• Daemon management — multi-daemon DataScript store, selection, autoheal
• Elisp helpers — template system for eval-elisp calls
• Olympus — grid layout calculation for multi-buffer arrangements
• Notifications — desktop notification integration
• cljel transpilation — Clojure-to-Elisp source files for Emacs-side integration

Architecture

hive-emacs follows the IAddon protocol pattern. It registers itself via classpath scanning:

;; META-INF/hive-addons/hive-emacs.edn
{:addon/id           "hive.emacs"
 :addon/type         :native
 :addon/init-ns      "hive-emacs.init"
 :addon/init-fn      "init-as-addon!"
 :addon/capabilities #{:tools :editor :health-reporting}}

The init pipeline follows the nil-railway pattern: resolve-deps → register → init → store.

Usage

Add as a git dependency in your deps.edn:

io.github.hive-agi/hive-emacs
{:git/tag "v0.1.0" :git/sha "94641c5d79ee80b713762569c88ca2b75eda7756"}

hive-mcp's classpath scanner will auto-detect and initialize the addon.
