|
<p>xplr is a terminal UI based file explorer that aims to increase our terminal
|
|
productivity by being a flexible, interactive orchestrator for the ever growing
|
|
awesome command-line utilities that work with the file-system.</p>
|
|
<p>To achieve its goal, xplr strives to be a fast, minimal and more importantly,
|
|
hackable file explorer.</p>
|
|
<p>xplr is not meant to be a replacement for the standard shell commands or the
|
|
GUI file managers. Rather, it aims to integrate them all and expose an
|
|
intuitive, scriptable, keyboard controlled, real-time visual interface, also
|
|
being an ideal candidate for further integration, enabling the users to achieve
|
|
insane terminal productivity.</p>
|
|
<h2 id="features"><a class="header" href="#features">Features</a></h2>
|
|
<h3 id="hackable"><a class="header" href="#hackable">Hackable</a></h3>
|
|
<p>xplr is built with configurability in mind. So it allows you to perform a vast
|
|
set of operations and make it behave just the way you want.</p>
|
|
<p>A few things you can do with the xplr configuration</p>
|
|
<ul>
|
|
<li><a href="layouts.html">Hack the layout</a></li>
|
|
<li><a href="modes.html">Hack the key bindings</a></li>
|
|
<li><a href="awesome-plugins.html">Extend with plugins</a></li>
|
|
</ul>
|
|
<h2 id="fast"><a class="header" href="#fast">Fast</a></h2>
|
|
<p>Although speed is not the primary concern, xplr is already fast enough so that
|
|
you can take it out for a walk into your <code>node_modules</code> or <code>/nix/store</code> any
|
|
time you want. I currently
|
|
<a href="https://github.com/sayanarijit/xplr/tree/main/benches">measure the most commonly used operations</a>
|
|
and I have seen it improve significantly over time, and it's only the start.</p>
|
|
<p><strong>Tip:</strong> A quick and easy way to optimize UI rendering is reducing the number
|
|
of columns in the table.</p>
|
|
<p><strong>Note:</strong> If you feel xplr is not behaving at its optimal, this is probably
|
|
because I am waiting for someone to complain. I want to avoid optimizing things
|
|
I don't need to, because optimization often requires either complexity or
|
|
feature sacrifice or both.</p>
|
|
<h2 id="minimalist"><a class="header" href="#minimalist">Minimalist</a></h2>
|
|
<p>xplr prefers to stay minimal, both in terms of features and binary size, but
|
|
just like speed, minimalism isn't as aggressively pursued as configurability.
|
|
If adding some feature, lines of code, or a dependency allows the users to be a
|
|
little more productive or allows xplr to be a little more configurable, it will
|
|
be considered. But of-course, the <code>bulk vs productivity gain per user</code> balance
|
|
will also be considered in the decision-making.</p>
|
|
<h2 id="other-features"><a class="header" href="#other-features">Other features</a></h2>
|
|
<ul>
|
|
<li><a href="https://github.com/sayanarijit/xplr/discussions/183">Embedded LuaJIT</a> for
|
|
portability and extensibility.</li>
|
|
<li><strong>Switchable recover mode:</strong> Saves you from doing unwanted things when in a
|
|
hurry.</li>
|
|
<li><strong>Sane (vim-like) defaults:</strong>
|
|
<ul>
|
|
<li>Use <code>h</code>, <code>j</code>, <code>k</code>, <code>l</code> or arrow keys
|
|
for basic navigation.</li>
|
|
<li>Go to top using <code>g</code> <code>g</code>, and bottom using <code>G</code>.</li>
|
|
<li>Travel history using <code>ctrl-o</code> and <code>ctrl-i</code>.</li>
|
|
<li>Go to home directory using <code>~</code>.</li>
|
|
<li>Enter search mode with <code>/</code> or <code>ctrl-f</code>.</li>
|
|
<li>Go to absolute index (e.g. <code>4</code>) using <code>4</code> <code>enter</code> or
|
|
<code>:</code> <code>4</code> <code>enter</code>.</li>
|
|
<li>Go to relative index (e.g. <code>4</code> <code>down</code>) using <code>4</code> <code>down</code> or
|
|
<code>:</code> <code>4</code> <code>down</code>.</li>
|
|
<li>Follow symlink using <code>g</code> <code>f</code>.</li>
|
|
<li>Open in GUI using <code>g</code> <code>x</code>.</li>
|
|
<li>Spawn terminal using <code>:</code> <code>!</code>.</li>
|
|
<li>Toggle selection using <code>v</code> or <code>space</code>.</li>
|
|
<li>Toggle select all using <code>V</code> or <code>ctrl-a</code>.</li>
|
|
<li>Clear selections using <code>ctrl-u</code>.</li>
|
|
</ul>
|
|
</li>
|
|
<li><strong>Separate keys for navigation:</strong> navigation keys are separated from the
|
|
action keys (e.g. file opening action) to avoid mistakenly performing
|
|
unwanted actions while navigating.</li>
|
|
<li><strong>Always visible panels</strong> to save you brain cycles:
|
|
<ul>
|
|
<li>Selection list.</li>
|
|
<li>Help menu.</li>
|
|
<li>Input & logs.</li>
|
|
<li>Filter and sort pipeline.</li>
|
|
</ul>
|
|
</li>
|
|
<li><strong>Batch creation:</strong> Create multiple files and directories without repeating
|
|
keys.</li>
|
|
<li><strong>Batch sort & filter:</strong> Apply sorters and filters in without repeating keys.</li>
|
|
<li><strong>Custom file properties:</strong> Display custom file properties with custom colors
|
|
in the table using Lua functions.</li>
|
|
<li><strong>Input buffer:</strong> Read user input using the built-in input buffer with
|
|
customizable behavior.</li>
|
|
<li><strong>Switchable layouts:</strong> Switch layouts dynamically without leaving <code>xplr</code>.</li>
|
|
<li><strong>Saved locations:</strong> Never lose context when traveling back and forth
|
|
directories.</li>
|
|
<li><strong>Auto refresh state:</strong> Auto refresh app state when the <code>$PWD</code> changes.</li>
|
|
<li><strong>Manually refresh UI</strong> when other apps mess it up.</li>
|
|
<li><strong>FIFO-based previews:</strong> Easy to manage FIFO file that can be used to
|
|
<a href="https://github.com/sayanarijit/xplr/pull/229">integrate with previewers</a>.</li>
|
|
<li><strong>Different quit options:</strong>
|
|
<ul>
|
|
<li>Quit with success without any output (<code>q</code>).</li>
|
|
<li>Quit with success and the result printed on stdout (<code>enter</code>).</li>
|
|
<li>Quit with success and the present working directory printed on stdout
|
|
(<code>:</code> <code>q</code> <code>p</code>).</li>
|
|
<li>Quit with success and the path under focus printed on stdout
|
|
(<code>:</code> <code>q</code> <code>f</code>).</li>
|
|
<li>Quit with success and the selection printed on stdout
|
|
(<code>:</code> <code>q</code> <code>s</code>).</li>
|
|
<li>Quit with failure (<code>ctrl-c</code>).</li>
