|
<p>xplr is a modal file explorer. That means the users switch between different
|
|
modes, each containing a different set of key bindings to avoid clashes. Users
|
|
can switch between these modes at run-time.</p>
|
|
<p>The modes can be configured using the <code>xplr.config.modes</code> Lua API.</p>
|
|
<p>It contains the following fields:</p>
|
|
<ul>
|
|
<li><a href="#builtin">builtin</a></li>
|
|
<li><a href="#custom">custom</a></li>
|
|
</ul>
|
|
<h2 id="builtin"><a class="header" href="#builtin">builtin</a></h2>
|
|
<p>Type: mapping of string and <a href="#mode">Mode</a></p>
|
|
<p>This is exposed by the <code>xplr.config.modes.builtin</code> API.</p>
|
|
<p>xplr by default provides the following builtin modes:</p>
|
|
<ul>
|
|
<li>default</li>
|
|
<li>recover</li>
|
|
<li>selection_ops</li>
|
|
<li>create</li>
|

<li>create_directory</li>
|
|
<li>create_file</li>
|

<li>number</li>

<h2 id="tutorial-adding-a-new-mode"><a class="header" href="#tutorial-adding-a-new-mode">Tutorial: Adding a New Mode</a></h2>
|
|
<p>Assuming xplr is <a href="install.html">installed</a> and <a href="post-install.html">setup</a>, let's
|
|
add our own mode to integrate xplr with <a href="https://github.com/junegunn/fzf">fzf</a>.</p>
|
|
<p>We'll call it <code>fzxplr</code> mode.</p>
|
|
<p>First, let's add a custom mode called <code>fzxplr</code>, and map the key <code>F</code> to an
|
|
action that will call <code>fzf</code> to search and focus on a file or enter into a
|
|
directory.</p>
|
|
<pre><code class="language-lua">xplr.config.modes.custom.fzxplr = {
|
|
name = "fzxplr",
|
|
key_bindings = {
|
|
on_key = {
|
|
F = {
|
|
help = "search",
|
|
messages = {
|
|
{
|
|
BashExec = [===[
|
|
PTH=$(cat "${XPLR_PIPE_DIRECTORY_NODES_OUT:?}" | awk -F/ '{print $NF}' | fzf)
|
|
if [ -d "$PTH" ]; then
|
|
echo ChangeDirectory: "'"${PWD:?}/${PTH:?}"'" >> "${XPLR_PIPE_MSG_IN:?}"
|
|
else
|
|
echo FocusPath: "'"${PWD:?}/${PTH:?}"'" >> "${XPLR_PIPE_MSG_IN:?}"
|
|
fi

]===]
|
|
},
|
|
"PopMode",
|
|
},
|
|
},
|
|
},
|
|
default = {
|
|
messages = {
|
|
"PopMode",
|
|
},
|
|
},
|
|
},
|
|
}
|
|
</code></pre>
|
|
<p>As you can see, the key <code>F</code> in mode <code>fzxplr</code> (the name can be anything)
|
|
executes a script in <code>bash</code>.</p>
|
|
<p><code>BashExec</code>, <code>PopMode</code>, <code>SwitchModeBuiltin</code>, <code>ChangeDirectory</code> and <code>FocusPath</code>
|
|
are <a href="message.html">messages</a>, <code>$XPLR_PIPE_MSG_IN</code>,
|
|
<code>$XPLR_PIPE_DIRECTORY_NODES_OUT</code> are
|
|
<a href="message.html#environment-variables">environment variables</a> exported by <code>xplr</code>
|
|
before executing the command. They contain the path to the
|
|
<a href="message.html#input-pipe">input</a> and <a href="message.html#output-pipes">output</a> pipes that
|
|
allows external tools to interact with <code>xplr</code>.</p>
|
|
<p>Now that we have our new mode ready, let's add an entry point to this mode via
|
|
the <code>default</code> mode.</p>
|
|
<pre><code class="language-lua">xplr.config.modes.builtin.default.key_bindings.on_key["F"] = {
|
|
help = "fzf mode",
|
|
messages = {
|
|
{ SwitchModeCustom = "fzxplr" },
|
|
},
|
|
}
|
|
</code></pre>
|
|
<p>Now let's try out the new <code>xplr</code>-<code>fzf</code> integration.</p>
