package gemini // import "github.com/jackdoe/net-gemini"

gemini server implementation, check out gemini://gemini.circumlunar.space/
inspired by https://tildegit.org/solderpunk/molly-brown

Example:

     package main

     import (
     	"log"

     	gemini "github.com/jackdoe/net-gemini"
     )

     func main() {
    	gemini.HandleFunc("/example", func(w *gemini.Response, r *gemini.Request) {
    		if len(r.URL.RawQuery) == 0 {
    			w.SetStatus(gemini.StatusInput, "what is the answer to the ultimate question")
    		} else {
    			w.SetStatus(gemini.StatusSuccess, "text/gemini")
    			answer := r.URL.RawQuery
    			w.Write([]byte("HELLO: " + r.URL.Path + ", yes the answer is: " + answer))
    		}
    	})

    	gemini.Handle("/", gemini.FileServer(*root))
     	log.Fatal(gemini.ListenAndServeTLS("localhost:1965", "localhost.crt", "localhost.key"))
     }

You can also checkout cmd/main.go as an example.

Make sure to generate your cert for localhost:

    openssl req \
            -x509 \
            -out localhost.crt \
            -keyout localhost.key \
            -newkey rsa:2048 \
            -nodes \
            -sha256 \
            -subj '/CN=localhost' \
            -extensions EXT \
            -config <( printf "[dn]\nCN=localhost\n[req]\ndistinguished_name = dn\n[EXT]\nsubjectAltName=DNS:localhost\nkeyUsage=digitalSignature\nextendedKeyUsage=serverAuth")
