The examples in the README use the Temple library to demonstrate that Tableau can be used with any markup language of your choice. You could easily use the builtin EEx, or use HEEx, Surface, or HAML.
Layouts are modules that use the use Tableau.Layout macro.
Layouts have access to the @site and @page assign.
The @site assign contains your site's config.
The @page assign contains all the options passed to the use Tableau.Page macro.
defmodule MySite.RootLayout do
use Tableau.Layout
import Temple
def template(assigns) do
temple do
"<!DOCTYPE html>"
html lang: "en" do
head do
meta charset: "utf-8"
meta http_equiv: "X-UA-Compatible", content: "IE=edge"
meta name: "viewport", content: "width=device-width, initial-scale=1.0"
title do
@page.some_assign
end
link rel: "stylesheet", href: "/css/site.css"
end
body class: "font-sans" do
main class: "container mx-auto px-2" do
div class: "border-4 border-green-500" do
a class: "text-blue-500 hover:underline", href: "/about" do
"About"
end
a class: "text-blue-500 hover:underline", href: "/posts" do
"Posts"
end
render @inner_content
end
end
end
if Mix.env() == :dev do
c &Tableau.live_reload/1
end
end
end
end
endPages are modules that use the use Tableau.Page macro.
Required options:
:layout- which layout module to use.:permalink- the permalink of the page
Any remaining options are arbitrary and will be available under the @page assign available to layout and page templates.
defmodule MySite.AboutPage do
use Tableau.Page,
layout: MySite.RootLayout,
permalink: "/about",
some_assign: "foo"
import Temple
def template(assigns) do
temple do
span class: "text-red-500 font-bold" do
"i'm a super cool and smart!"
end
end
end
endYou can specify a set of directories/files to watch for changes, and the browser will automatically refresh.

patterns: [
~r"lib/layouts/.*.ex",
~r"lib/pages/.*.ex",
~r"lib/components.ex",
~r"_site/.*.css"
]All you need to do is render the Tableau.live_reload/1 component right after your body tag.

endYou can arbitrarily start other build tools as "watchers". This is inspired by the way Phoenix does it.
# config/config.exs
import Config
config :tableau, :assets,
npx: [
"tailwindcss",
"-o",
"_site/css/site.css",
"--watch"
]
# or if you are using a package similar to the TailwindCSS hex package
config :tableau, :assets, tailwind: {Tailwind, :install_and_run, [:default, ~w(--watch)]}
import_config "#{config_env()}.exs"This will start a long running process that will independently build your CSS as it sees files change.
These are started automatically when you run mix tableau.server.
Other static assets can be copied into the "out" directory by placing them in an extra directory in the root of your project.
This directory can be configured.
config :tableau, :config,
include_dir: "static"The dev server can be started with mix tableau.server. On file change, a browser reload will be triggered and the page your requesting will be re-built during the request.
