sigil-socket

TCP, UDP, and Unix domain socket operations for Sigil. Provides network socket primitives suitable for both blocking and non-blocking I/O, including integration with Sigil's coroutine-based async runtime.

This package was extracted from the sigil monorepo — the in-tree history under packages/sigil-socket/ is preserved here as master.

Usage

(import (sigil socket))

;; TCP client
(let ((sock (tcp-connect "example.com" 80)))
  (socket-write-line sock "GET / HTTP/1.0")
  (socket-write-line sock "")
  (display (socket-read-all sock))
  (socket-close sock))

;; TCP server
(let ((server (tcp-listen 8080)))
  (let loop ()
    (let ((client (tcp-accept server)))
      (socket-write-line client "Hello!")
      (socket-close client)
      (loop))))

;; UDP
(let ((sock (udp-socket)))
  (udp-send sock "127.0.0.1" 5000 "Hello")
  (socket-close sock))
