yagm

yagm is an acronym of Yet Another Go Mux.

YagmMux uses regular expressions to match an URL. If you're familiar with Django, the patterns match is almost the same.

YagmMux is also very close to http.ServeMux. You can replace your actual http.ServeMux by YagmMux without any problem.

Install

go get github.com/alexandrevicenzi/yagm

Usage

You can register your handlers as in http.ServeMux.

mux := yagm.New()
mux.HandleFunc("^/$", homeHandler)
mux.Handle("^/files", http.StripPrefix("/files", http.FileServer(http.Dir("./"))))
mux.HandleFunc("^/(?P<name>[a-zA-Z]+)$", helloHandler)

You can get the value of named groups with

params, ok := yagm.Params(request)
value, ok := params["group_name"]

or

value, ok := yagm.Param(request, "group_name")

Full Example

package main

import (
    "fmt"
    "net/http"

    "github.com/alexandrevicenzi/yagm"
)

func homeHandler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprint(w, "Hello World!")
}

func helloHandler(w http.ResponseWriter, r *http.Request) {
    name, ok := yagm.Param(r, "name")

    if !ok {
        name = "Unknown"
    }

    fmt.Fprintf(w, "Hello %s!", name)
}

func main() {
    mux := yagm.New()
    mux.HandleFunc("^/$", homeHandler)
    mux.Handle("^/files", http.StripPrefix("/files", http.FileServer(http.Dir("./"))))
    mux.HandleFunc("^/(?P<name>[a-zA-Z]+)$", helloHandler)
    http.ListenAndServe(":8000", mux)
}
