Dead simple filserver written in go as an alternative to python's simpleHTTPServer which invariably leads to frustration with it's sequential blocking access

fserv.go

package main

import (
	"flag"
	"fmt"
	"log"
	"net/http"
)

var (
	port = flag.Int("port", 8080, "server port")
	host = flag.String("host", "", "server host")
	dir  = flag.String("dir", ".", "base directory to host from")
)

type Logger struct {
	http.Handler
}

func (l Logger) ServeHTTP(w http.ResponseWriter, r *http.Request) {
	log.Printf("%s: %s\n", r.Method, r.URL)
	l.Handler.ServeHTTP(w, r)
}

func main() {
	flag.Parse()
	addr := fmt.Sprintf("%s:%d", *host, *port)
	logger := Logger{http.FileServer(http.Dir(*dir))}

	log.Printf("Hosting %s on %s\n", *dir, addr)
	log.Fatal(http.ListenAndServe(addr, logger))
