<h2 class="chapter">3 Tutorial</h2>
<p>The goal of this tutorial is to quickly create a barebones blog with
Haunt in order to demonstrate the basic workflow and key concepts.
</p>
<p>First, create a directory for the new site:
</p>
<div class="example">
<pre class="example">mkdir haunt-tutorial
cd haunt-tutorial
</pre></div>
<p>Next, create the site configuration file <samp>haunt.scm</samp>. This is
where all of the code for building the website will go.
</p>
<p>Here’s what a simple Haunt configuration looks like:
</p>
<div class="example">
<pre class="example">(use-modules (haunt asset)
(haunt site)
(haunt builder blog)
(haunt builder atom)
(haunt reader skribe))
(site #:title "My First Haunt Site"
#:domain "example.com"
#:default-metadata
'((author . "Eva Luator")
(email . "eva@example.com"))
#:readers (list skribe-reader)
#:builders (list (blog)
(atom-feed)
(atom-feeds-by-tag)))
</pre></div>
<p>Haunt represents the full configuration of the website using the
<code>site</code> procedure. Site objects specify things like the site
title, the default metadata to use for posts, which markup formats are
supported, and which builders are used to generate web pages.
</p>
<p>With the above code saved into the <samp>haunt.scm</samp> file, the next
step is to create a <samp>posts</samp> directory and populate it with
articles to publish. Put the text below into a file named
<samp>posts/hello.skr</samp>:
</p>
<div class="example">
<pre class="example">(post
:title "Hello, World!"
:date (make-date* 2015 10 15)
:tags '("hello")
(h1 [Hello, World!])
(p [This is my very first Skribe document!]))
</pre></div>
<p>This is a
<a href="http://www.nongnu.org/skribilo/doc/user-3.html#skribe-syntax">Skribe</a> document. Skribe is one of the built-in languages that Haunt
knows how to work with. It’s basically Scheme, but with support for
writing literal text without quoting it all by enclosing it in square
brackets. The code above defines a post named “Hello, World!” with
a publishing date of 2015-10-15, whose contents are just a single
heading and a paragraph.
</p>
<p>To build the site, run <code>haunt build</code> to compile all of the
HTML pages. To view the results, run <code>haunt serve</code> and visit
<a href="http://localhost:8080">http://localhost:8080</a> in a web browser. <code>haunt serve</code>
is a handy utility that serves the contents of the website using
Guile’s built-in HTTP server. Since the blog builder was specified in
<samp>haunt.scm</samp>, the default index page is a simple listing of all
posts, which for now is a single post. Clicking on the post title
will display a page with only that post’s contents.
</p>
<p>In addition to the basic blog builder, the <samp>haunt.scm</samp> file
specifies two additional builders for Atom feeds. The
<code>atom-feed</code> builder creates a feed of all posts located at
<a href="http://localhost:8080/feed.xml">http://localhost:8080/feed.xml</a>. The <code>atom-feeds-by-tag</code>
builder creates one feed for each unique tag specified in the post
metadata. There’s only one tag right now, “hello”, and its feed is
located at <a href="http://localhost/feeds/tags/hello.xml">http://localhost/feeds/tags/hello.xml</a>.
</p>
<p>Tweaking a post, rebuilding the site, and viewing the results in a web
browser is the typical Haunt workflow. However, having to run
<code>haunt build</code> every after each edit is tedious. To address
this, run <code>haunt serve --watch</code>. The Haunt web server, in
addition to serving web pages, will now watch for changes to important
files and automatically rebuild the site when they are edited. This
streamlines the workflow into an edit, save, view loop.
</p>
<p>Now that we’ve introduced the basic utilities and concepts, continue
reading this manual to learn more about Haunt’s command-line and
programming interfaces.
