Page definition is an entry point of out page rendering. The most basic way to define a page is to use template builder. Let's see how it works:

package main

import (


func PageIndex(core *kyoto.Core) {
    lifecycle.Init(core, func() {
        core.State.Set("Content", "Hello, Kyoto!")
    render.Template(core, func() *template.Template {
        return template.Must(template.New("page.index.html").Funcs(render.FuncMap(core)).ParseGlob("*.html"))
<!DOCTYPE html>
    <title>Page Index</title>
    <h1>{{ .Content }}</h1>

First, we will get the terms right:

  • Core receiver - function, receiving a kyoto.Core as an argument.
  • Adapter - function, that interacts with a core.

We need to understand is that everything in this library built around kyoto.Core. Every page, every component, every module interacts with a core. Kyoto is not a single package. It's a set of packages that are built around a core.

Let's return to the example. You can see a core receiver here. Every page or component is a core receiver. To add page functionality to this core receiver, we are using render module. With a help of render.Template we are specifying a template builder.

Also, as you can see, there is a lifecycle.Init adapter. This adapter is responsible for defining of initializing function. Lifecycle functionality will be described in a Basics • Lifecycle documentation category.

Another thing you may notice in this example is setting of a state. To interact with a state, we are using a kyoto.State instance inside of a core. There are 3 methods for state modification: Set, Get, Del. For more information, check Basics • State documentation category.
