<p>Nyxt has a brand new dark-mode!</p>
|
|
<p><img src="../static/image/article/wiki-cichlid-dark.png" /></p>
|
|
<h1 id="how-to-use-it">How to use it?</h1>
|
|
<p>Simple, just enable <code>dark-mode</code>. That's it! Nyxt will do its best to attempt to configure the screen to be dark, while remaining legible and leaving images/videos unaltered.</p>
|
|
<p>If you want to selectively enable/disable dark-mode for different domains, you can leverage auto-mode to automatically/enable dark-mode. To find out more check out our article about auto-mode <a href="https://nyxt.atlas.engineer/article/auto-mode.org">here</a>.</p>
|
|
<h1 id="extended-customization-options">Extended Customization Options</h1>
|
|
<p>If you want to change the behavior of dark-mode, you have a couple of options:</p>
|
|
<p>You can either:</p>
|
|
<ul>
|
|
<li>match styles based on the domain</li>
|
|
<li>match styles based on a custom predicate</li>
|
|
</ul>
|
|
<p>You can source your styles from:</p>
|
|
<ul>
|
|
<li>embedding them directly in your init file</li>
|
|
<li>placing them in a file on your system</li>
|
|
<li>downloading them from a remote URL</li>
|
|
</ul>
|
|
<p>In order to do this you must make a <code>style-association</code> struct and add it to your <code>style-associations</code> list of your <code>dark-mode</code> configuration.</p>
|
|
<p>Let's begin with our struct definition:</p>
|
|
<div class="sourceCode" id="style-association-struct" data-org-language="lisp"><pre class="sourceCode commonlisp"><code class="sourceCode commonlisp"><a class="sourceLine" id="style-association-struct-1" data-line-number="1">(<span class="kw">defstruct</span><span class="fu"> style-association</span></a>
|
|
<a class="sourceLine" id="style-association-struct-2" data-line-number="2"> (url)</a>
|
|
<a class="sourceLine" id="style-association-struct-3" data-line-number="3"> (predicate)</a>
|
|
<a class="sourceLine" id="style-association-struct-4" data-line-number="4"> (style)</a>
|
|
<a class="sourceLine" id="style-association-struct-5" data-line-number="5"> (style-file)</a>
|
|
<a class="sourceLine" id="style-association-struct-6" data-line-number="6"> (style-url))</a></code></pre></div>
|
|
<ul>
|
|
<li>If you want to match based on URL, provide a URL.</li>
|
|
<li><p>If you want to match based on a predicate, provide a predicate that accepts a single argument (the URL) and returns t or nil depending on whether the style should be applied.</p></li>
|
|
<li>If you want to specify a style directly in your <code>style-association</code> struct, use the <code>style</code>.</li>
|
|
<li>If you want to specify your style via a file use a <code>style-file</code> with a full path to the file to load the style from.</li>
|
|
<li><p>If you want to specify your style via a URL use a <code>style-url</code> with a full path to the URL with the file to load the style from. Nyxt will download the style and cache it on your system (by default in <code>~/.local/share/nyxt/dark-mode-css-cache</code>).</p></li>
|
|
</ul>
|
|
<p>Using this struct definition let's go through some examples:</p>
|
|
<h2 id="setting-the-style-based-on-url">Setting the style based on URL</h2>
|
|
<p>In the example below if we visit "<a href="https://example.org" class="uri">https://example.org</a>", our style will be applied.</p>
|
|
<div class="sourceCode" id="style-association-simple" data-org-language="lisp"><pre class="sourceCode commonlisp"><code class="sourceCode commonlisp"><a class="sourceLine" id="style-association-simple-1" data-line-number="1">(make-style-association</a>
|
|
<a class="sourceLine" id="style-association-simple-2" data-line-number="2"> :url <span class="st">"https://example.org"</span></a>
|
|
<a class="sourceLine" id="style-association-simple-3" data-line-number="3"> :style (cl-css:css</a>
|
|
<a class="sourceLine" id="style-association-simple-4" data-line-number="4"> '((body</a>
|
|
<a class="sourceLine" id="style-association-simple-5" data-line-number="5"> :background-color <span class="st">"black"</span>))))</a></code></pre></div>
|
|
<h2 id="setting-the-style-based-on-a-predicate">Setting the style based on a predicate</h2>
|
|
<p>In the example below if the length of the URL is greater than 10 characters, our style will be applied.</p>
|
|
<div class="sourceCode" id="style-association-predicate" data-org-language="lisp"><pre class="sourceCode commonlisp"><code class="sourceCode commonlisp"><a class="sourceLine" id="style-association-predicate-1" data-line-number="1">(make-style-association</a>
|
|
<a class="sourceLine" id="style-association-predicate-2" data-line-number="2"> <span class="bu">:predicate</span> (<span class="kw">lambda</span> (url) (<span class="op">></span> (<span class="kw">length</span> url) <span class="dv">10</span>))</a>
|
|
<a class="sourceLine" id="style-association-predicate-3" data-line-number="3"> :style (cl-css:css</a>
|
|
<a class="sourceLine" id="style-association-predicate-4" data-line-number="4"> '((body</a>
|
|
<a class="sourceLine" id="style-association-predicate-5" data-line-number="5"> :background-color <span class="st">"black"</span>))))</a></code></pre></div>
|
|
<h2 id="setting-the-style-from-a-file">Setting the style from a file</h2>
|
|
<p>In the example below, our style will be sourced from a file.</p>
|
|
<div class="sourceCode" id="style-association-predicate" data-org-language="lisp"><pre class="sourceCode commonlisp"><code class="sourceCode commonlisp"><a class="sourceLine" id="style-association-predicate-1" data-line-number="1">(make-style-association</a>
|
|
<a class="sourceLine" id="style-association-predicate-2" data-line-number="2"> :url <span class="st">"https://example.org"</span></a>
|
|
<a class="sourceLine" id="style-association-predicate-3" data-line-number="3"> :style-file <span class="st">"/user/local/file.css"</span>)</a></code></pre></div>
|
|
<h2 id="setting-the-style-from-a-url">Setting the style from a URL</h2>
|
|
<p>In the example below, our style will be sourced from a URL.</p>
|
|
<div class="sourceCode" id="style-association-predicate" data-org-language="lisp"><pre class="sourceCode commonlisp"><code class="sourceCode commonlisp"><a class="sourceLine" id="style-association-predicate-1" data-line-number="1">(make-style-association</a>
|
|
<a class="sourceLine" id="style-association-predicate-2" data-line-number="2"> :url <span class="st">"https://example.org"</span></a>
|
|
<a class="sourceLine" id="style-association-predicate-3" data-line-number="3"> :style-url <span class="st">"https://www.example.org/css-file"</span>)</a></code></pre></div>
|
|
<h2 id="setting-our-style-association-list">Setting our <code>style-association-list</code></h2>
|
|
<p>When we've collected our list of <code>style-association</code> objects, we will want to set our <code>dark-mode</code> to use them. To do so we can do something like the following:</p>
|
|
<div class="sourceCode" id="dark-mode-configuration" data-org-language="lisp"><pre class="sourceCode commonlisp"><code class="sourceCode commonlisp"><a class="sourceLine" id="dark-mode-configuration-1" data-line-number="1">(define-configuration nyxt/style-mode::dark-mode</a>
|
|
<a class="sourceLine" id="dark-mode-configuration-2" data-line-number="2"> ((nyxt/style-mode::style-associations</a>
|
|
<a class="sourceLine" id="dark-mode-configuration-3" data-line-number="3"> (<span class="kw">list</span> (nyxt/style-mode::make-style-association :url <span class="st">"https://nyxt.atlas.engineer"</span></a>
|
|
<a class="sourceLine" id="dark-mode-configuration-4" data-line-number="4"> :style (cl-css:css</a>
|
|
<a class="sourceLine" id="dark-mode-configuration-5" data-line-number="5"> '((body</a>
|
|
<a class="sourceLine" id="dark-mode-configuration-6" data-line-number="6"> :background-color <span class="st">"gray"</span>))))))))</a></code></pre></div>
|
|
<p>The above configuration will set the background color of <a href="https://nyxt.atlas.engineer" class="uri">https://nyxt.atlas.engineer</a> to gray.</p>
|
|
<p>Here are some more examples of the default Nyxt dark-mode in action!</p>
