|
||
<p>To keep source code neat and indented, we’re adding spaces to our templates. LiquidJS offers whitespace control capabilities to eliminate these unwanted whitespaces in output HTML.</p>
|
||
<h2 id="via-Markups" class="article-heading"><a href="#via-Markups" class="headerlink" title="via Markups"></a>via Markups<a class="article-anchor" href="#via-Markups" aria-hidden="true"></a></h2><p>By default, all tags and output markups lines will generate a NL (<code>\n</code>), and whitespaces if there’s any indentation. For example:</p>
|
||
<pre class="line-numbers language-liquid" data-language="liquid"><code class="language-liquid"><span class="token liquid language-liquid"><span class="token delimiter punctuation">{%</span> author <span class="token operator">=</span> <span class="token string">"harttle"</span> <span class="token delimiter punctuation">%}</span></span>
|
||
<span class="token liquid language-liquid"><span class="token delimiter punctuation">{{</span> author <span class="token delimiter punctuation">}}</span></span><span aria-hidden="true" class="line-numbers-rows"><span></span><span></span></span></code></pre>
|
||
|
||
<p>Outputs (note the blank link):</p>
|
||
<pre class="line-numbers language-none"><code class="language-none">
|
||
harttle<span aria-hidden="true" class="line-numbers-rows"><span></span><span></span></span></code></pre>
|
||
|
||
<p>We can include hyphens in your tag syntax (<code>{{-`, `-}}`, `{%-</code>, <code>-%}</code>) to strip whitespace from left or right. For example:</p>
|
||
<pre class="line-numbers language-liquid" data-language="liquid"><code class="language-liquid"><span class="token liquid language-liquid"><span class="token delimiter punctuation">{%</span> <span class="token keyword">assign</span> author <span class="token operator">=</span> <span class="token string">"harttle"</span> <span class="token delimiter punctuation">-%}</span></span>
|
||
<span class="token liquid language-liquid"><span class="token delimiter punctuation">{{</span> author <span class="token delimiter punctuation">}}</span></span><span aria-hidden="true" class="line-numbers-rows"><span></span><span></span></span></code></pre>
|
||
|
||
<p>Outputs:</p>
|
||
<pre class="line-numbers language-none"><code class="language-none">harttle<span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
|
||
|
||
<p>In this case, the <code>-%}</code> strips the whitespace from the right side of the <code>assign</code> tag.</p>
|
||
<h2 id="via-Options" class="article-heading"><a href="#via-Options" class="headerlink" title="via Options"></a>via Options<a class="article-anchor" href="#via-Options" aria-hidden="true"></a></h2><p>Alternatively, LiquidJS provides these per engine options to enable whitespace control without sweeping changes of your templates:</p>
|
||
<ul>
|
||
<li><code>trimTagLeft</code></li>
|
||
<li><code>trimTagRight</code></li>
|
||
<li><code>trimValueLeft</code></li>
|
||
<li><code>trimValueRight</code></li>
|
||
</ul>
|
||
<p><a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/harttle/liquidjs">LiquidJS</a> will <strong>NOT</strong> trim any whitespace by default, aka. above options all default to <code>false</code>. For details of these options, see the <a href="../api/interfaces/liquid_options_.liquidoptions.html">options</a>.</p>
|
||
<h2 id="Greedy-Mode" class="article-heading"><a href="#Greedy-Mode" class="headerlink" title="Greedy Mode"></a>Greedy Mode<a class="article-anchor" href="#Greedy-Mode" aria-hidden="true"></a></h2><p>In greedy mode (enabled by the <a href="../api/interfaces/liquid_options_.liquidoptions.html#Optional-greedy">greedy option</a>), all consecutive whitespace chars (including <code>\n</code>) will be trimmed. Greedy mode is enabled by default to be compliant with <a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/Shopify/liquid">shopify/liquid</a>.</p>
