Emacs 9P Server

This project implements a 9P server in Emacs Lisp. The 9P protocol is a network protocol used for distributed file systems, originally developed for the Plan 9 operating system.

Features

• Server can be started, stopped, and restarted from within Emacs
• Work in progress: Implementation of the 9P2000 protocol
• Work in progress: Virtual filesystem for RPC functionality
• Work in progress: vfs and 9p server integration.

9P2000 Protocol (Work in Progress)

The implementation of the 9P2000 protocol is currently under development.

Usage

;; start the 9p server
(9p-start-server)

;; stop the 9p server
(9p-stop-server)

;; restart a running 9p server
(9p-restart-server)

# send ls command using plan9port 9p client
9p -a 'unix!/tmp/emacs-9p-server.sock' ls /

Virtual Filesystem (Work in Progress)

An RPC interface will be exposed over 9P to enable remote interactions with Emacs. The implementation is currently under development.

Usage

;; a functioning example
(vfs-register-directory "/b/")
(vfs-register-fileop "/b/" 'directory-files 'vfs-op-b-directory-files)

;; returns a list of open buffers
(directory-files "/b/")

Limitations

• Currently only supports registering a fileops handler for individual directories; the handler registration does not propagate to subdirectories.

Testing

9pel uses my custom testing framework, LispyMcTestFace for unit and integration testing. Give it a try, you might like it.
