Static Sites With Bash
</span>
<div class="post-text">
<p>After going through a bunch of static site generators
(<a href="https://blog.getpelican.com/">pelican</a>,
<a href="https://gohugo.io">hugo</a>,
<a href="https://github.com/icyphox/vite">vite</a>), I decided to roll
my own. If you are more of the ‘show me the code’ kinda guy,
<a href="https://github.com/nerdypepper/site">here</a> you go.</p>
<h3 id="Text%20formatting">Text formatting</h3>
<p>I chose to write in markdown, and convert
to html with <a href="https://kristaps.bsd.lv/lowdown/">lowdown</a>.</p>
<h3 id="Directory%20structure">Directory structure</h3>
<p>I host my site on GitHub pages, so
<code>docs/</code> has to be the entry point. Markdown formatted posts
go into <code>posts/</code>, get converted into html, and end up in
<code>docs/index.html</code>, something like this:</p>
<pre><code>posts=$(ls -t ./posts) # chronological order!
for f in $posts; do
file="./posts/"$f # `ls` mangled our file paths
echo "generating post $file"
html=$(lowdown "$file")
echo -e "html" >> docs/index.html
done
</code></pre>
<h3 id="Assets">Assets</h3>
<p>Most static site generators recommend dropping image
assets into the site source itself. That does have it’s
merits, but I prefer hosting images separately:</p>
<pre><code># strip file extension
ext="${1##*.}"
# generate a random file name
id=$( cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 2 | head -n 1 )
id="$id.$ext"
# copy to my file host
scp -P 443 "$1" emerald:files/"$id"
echo "https://u.peppe.rs/$id"
</code></pre>
<h3 id="Templating">Templating</h3>
<p><a href="https://github.com/NerdyPepper/site/blob/master/generate.sh"><code>generate.sh</code></a>
brings the above bits and pieces together (with some extra
cruft to avoid javascript). It uses <code>sed</code> to produce nice
titles from the file names (removes underscores,
title-case), and <code>date(1)</code> to add the date to each post
listing!</p>
