should be able to set it up like this...

package main

import (
    "html/template"
    "net/http"
)

var (
    templates = template.Must(template.ParseGlob("templates/*"))
)

func base(w http.ResponseWriter, req *http.Request) {
    err := templates.ExecuteTemplate(w, "base", nil)
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
}

func main() {
    mux := http.NewServeMux()
    mux.HandleFunc("/", base)
    http.ListenAndServe(":8000", mux)
}

Also, with your go templates...need to make sure to always define the names even for partial templates. In a.html and b.html you would need to set them up like..

{{define "a"}}
what you already have for a
{{end}}

{{define "b"}}
what you already have for b
{{end}}

something like that anyways...good luck! 😄
