<p>This is a Lektor plugin that allows you to render Jinja2 inside your content fields that are string-like. For example, this means that inside your content fields that are of type string or Markdown, you can write Jinja logic, and access Lektor's <a href="https://www.getlektor.com/docs/templates/#template-context" rel="nofollow">Template Context</a>, and has access to all normal Jinja filters, including those provided by <a href="https://github.com/terminal-labs/lektor-slugify" rel="nofollow">other plugins</a>. In a Markdown field (or other field that is rendered - like <a href="https://github.com/fschulze/lektor-rst" rel="nofollow">rst</a>), the <strong>Jinja is processed first</strong>, then the formatting processor.</p>
|
|
<p>You can set and use Jinja variables, but they will only have meaning within their field that is being rendered.</p>
|
|
<p>With this plugin, you'll have to make sure the content that is rendered <strong>is valid Jinja</strong>. Jinja syntax erros will throw an exception. Don't forget about the handy <code>{% raw %} {% endraw %}</code> tags if you want content that is not valid Jinja.</p>
|
|
<p><strong>N.B.</strong> Using this plugin is rendering many more items with Jinja, and your build process will slow down as a result. As an early benchmark and anecdote, my small website's build time rose from 4.89s to 5.39s even while I actually had no Jinja-Content that needed rendering. I plan on adding the ability to configure this plugin later so that you don't have to run <em>everything</em> through Jinja if you don't want to.</p>
|
|
<h2>Examples</h2>
|
|
<p>Querying context: <code>{{ site.get('/').title }}</code> or <code>{{ this.path }}</code></p>
|
|
<p>Logic:</p>
|
|
<pre lang="jinja"><span class="cp">{%</span> <span class="k">set</span> <span class="nv">meaning_of_life</span><span class="o">,</span> <span class="nv">meaning_of_universe</span> <span class="o">=</span> <span class="nv">this.life</span><span class="o">,</span> <span class="nv">this.universe</span> <span class="cp">%}</span><span class="x"></span>
|
|
<span class="cp">{%</span> <span class="k">if</span> <span class="nv">meaning_of_life</span> <span class="o">==</span> <span class="nv">meaning_of_universe</span> <span class="o">==</span> <span class="m">42</span> <span class="cp">%}</span><span class="x"></span>
|
|
<span class="x"> </span><span class="cp">{%</span> <span class="k">set</span> <span class="nv">meaning_of_it_all</span> <span class="o">=</span> <span class="nv">meaning_of_life</span> <span class="cp">%}</span><span class="x"></span>
|
|
<span class="cp">{%</span> <span class="k">else</span> <span class="cp">%}</span><span class="x"></span>
|
|
<span class="x"> </span><span class="cp">{%</span> <span class="k">set</span> <span class="nv">meaning_of_it_all</span> <span class="o">=</span> <span class="s1">'Undefined'</span> <span class="cp">%}</span><span class="x"></span>
|
|
<span class="cp">{%</span> <span class="k">endif</span> <span class="cp">%}</span><span class="x"></span>
|
|
<span class="cp">{{</span> <span class="nv">meaning_of_it_all</span> <span class="cp">}}</span><span class="x"></span>
|
|
</pre>
|
|
<p>Jinja in Markdown:</p>
|
|
<pre lang="jinja"><span class="x">[link text](</span><span class="cp">{{</span> <span class="nv">this</span><span class="o">|</span><span class="nf">url</span> <span class="cp">}}</span><span class="x">)</span>
|
|
</pre>
|
|
<p>Jinja in reStructuredText:</p>
|
|
<pre lang="jinja"><span class="x">`link text <</span><span class="cp">{{</span> <span class="nv">this</span><span class="o">|</span><span class="nf">url</span> <span class="cp">}}</span><span class="x">>`_</span>
|
|
</pre>
|

|
<h2>Possible future of this plugin.</h2>
|
|
<p>This Plugin opens the door to some pretty powerful and pretty funky functionality. Here's some food for though:</p>
|
|
<ul>
|
|
<li>Currently every every string-like field in <code>_data</code> and <code>_blocks</code> is processed, even things like <code>_slug</code> and <code>_template</code>. Can these other things be used?</li>
|
|
<li><a href="https://github.com/lektor/lektor/issues/541" rel="nofollow">Some people want to be able to include markdown in content files / declarations</a>. This plugin might pave the way toward that with <a href="https://github.com/terminal-labs/lektor-jinja-content/issues/3" rel="nofollow">includes and extends</a>.</li>
|
|
<li>Could we Jinjaify static files?</li>
|
|
<li><a href="https://github.com/terminal-labs/lektor-jinja-content/issues/4" rel="nofollow">Databags?</a></li>
|
|
<li><a href="https://github.com/terminal-labs/lektor-jinja-content/issues/2" rel="nofollow">What about modularity?</a></li>
|
|
</ul>
