trivial-sockets

A trivial networking library for undemanding Internet applications

Usage examples:

(with-open-stream (s (trivial-sockets:open-stream "www.google.com" 80)) 
  (format s "HEAD / HTTP/1.0~%Host: www.google.com~%~%") 
  (force-output s) 
  (loop 
    (let ((l (read-line s nil nil))) 
      (unless l (return)) 
      (princ l) (terpri))))

(trivial-sockets:with-server (s (:port 8913 :reuse-address t))
   (loop
    (with-open-stream (c (trivial-sockets:accept-connection s)) 
        (read-line c)
        (format c "Hi there!~%"))))

Proper documentation is in trivial-sockets.texi. If you have Texinfo installed you can convert this to DVI or PDF using texi2dvi or texi2pdf, or use makeinfo to create an Info file for use with Emacs or the standalone info reader.

Installation:

Use asdf-install.

• (asdf:operate 'asdf:load-op 'asdf-install)
• (asdf-install:install 'trivial-sockets)

Or if you don't have asdf-install but you do have asdf, create a symlink from a directory in your asdf:central-registry and run

• (asdf:operate 'asdf:load-op 'trivial-sockets)

Or if you don't have asdf, either (a) get it, or (b) compile the files by hand in an order that satisfies the dependencies in trivial-sockets.asd
