<h1><a class="header" href="#custom-pages-and-patches" id="custom-pages-and-patches">Custom Pages and Patches</a></h1>
<p>Tealdeer allows creating new custom pages, overriding existing pages as well as
extending existing pages.</p>
<p>The directory, where these custom pages and patches can be placed, follows OS
conventions. On Linux for instance, the default location is
<code>~/.local/share/tealdeer/pages/</code>. To print the path used on your system, simply
run <code>tldr --show-paths</code>.</p>
<p>The custom pages directory can be <a href="config_directories.html">overridden by the config
file</a>.</p>
<h2><a class="header" href="#custom-pages" id="custom-pages">Custom Pages</a></h2>
<p>To document internal command line tools, or if you want to replace an existing
tldr page with one that's better suited for you, place a file with the name
<code>&lt;command&gt;.page</code> in the custom pages directory. When calling <code>tldr &lt;command&gt;</code>,
your custom page will be shown instead of the upstream version in the cache.</p>
<p>Path:</p>
<pre><code>$CUSTOM_PAGES_DIR/&lt;command&gt;.page
</code></pre>
<p>Example:</p>
<pre><code>~/.local/share/tealdeer/pages/ufw.page
</code></pre>
<h2><a class="header" href="#custom-patches" id="custom-patches">Custom Patches</a></h2>
<p>Sometimes you don't want to fully replace an existing upstream page, but just
want to extend it with your own examples that you frequently need. In this
case, use a file called <code>&lt;command&gt;.patch</code>, it will be appended to existing
pages.</p>
<p>Path:</p>
<pre><code>$CUSTOM_PAGES_DIR/&lt;command&gt;.patch
</code></pre>
<p>Example:</p>
<pre><code>~/.local/share/tealdeer/pages/ufw.patch
</code></pre>
<h1><a class="header" href="#configuration" id="configuration">Configuration</a></h1>
<p>Tealdeer can be customized with a config file in <a href="https://toml.io/">TOML
format</a> called <code>config.toml</code>.</p>
<h2><a class="header" href="#configfile-path" id="configfile-path">Configfile Path</a></h2>
<p>The configuration file path follows OS conventions (e.g.
<code>$XDG_CONFIG_HOME/tealdeer/config.toml</code> on Linux). The paths can be queried
with the following command:</p>
<pre><code>$ tldr --show-paths
</code></pre>
<p>Creating the config file can be done manually or with the help of <code>tldr</code>:</p>
<pre><code>$ tldr --seed-config
</code></pre>
<p>On Linux, this will usually be <code>~/.config/tealdeer/config.toml</code>.</p>
<h2><a class="header" href="#config-example" id="config-example">Config Example</a></h2>
<p>Here's an example configuration file. Note that this example does not contain
all possible config options. For details on the things that can be configured,
please refer to the subsections of this documentation page
(<a href="config_display.html">display</a>, <a href="config_style.html">style</a>,
<a href="config_updates.html">updates</a> or <a href="config_directories.html">directories</a>).</p>

<h2><a class="header" href="#override-config-directory" id="override-config-directory">Override Config Directory</a></h2>
<p>The directory where the configuration file resides may be overwritten by the
environment variable <code>TEALDEER_CONFIG_DIR</code>. Remember to use an absolute path.
Variable expansion will not be performed on the path.</p>
<h2><a class="header" href="#override-cache-directory" id="override-cache-directory">Override Cache Directory</a></h2>
<p>Similarly, the cache directory where the pages are downloaded to, also follows
OS conventions. On Linux, it will usually be at <code>~/.cache/tealdeer/</code>. The path
can be overwritten using the environment variable <code>TEALDEER_CACHE_DIR</code>.
Remember to use an absolute path. Variable expansion will not be performed on
the path.</p>
<h1><a class="header" href="#section-display" id="section-display">Section: [display]</a></h1>

<pre><code>[display]

</code></pre>
<p>When enabled, <code>less -R</code> is used as pager. To override the pager command used,
set the <code>PAGER</code> environment variable.</p>
<p>NOTE: This feature is not available on Windows.</p>
<h2><a class="header" href="#compact" id="compact"><code>compact</code></a></h2>
<p>Set this to enforce more compact output, where empty lines are stripped out
(default <code>false</code>).</p>
<pre><code>[display]

<h1><a class="header" href="#section-style" id="section-style">Section: [style]</a></h1>
