# Awesome Hacks

Here's a list of cool xplr hacks, i.e. snippets of code that you can just copy
and paste into your [configuration][1] or the appropriate file, that are
too small or too niche for a full fledge [plugin][2].

Do you have something cool to share?

[Edit this file][3] or [share them here][4].

You can try these hacks by writing them to a file, say `hack.lua` and passing
it to xplr with `--extra-config` or `-C`.

```bash
xplr -C hack.lua
```

### cd on quit

Change directory using xplr.

- Author: [@sayanarijit][8]
- Tested on: Linux

NOTE: This is a shell hack, rather than Lua config hack. Add this in
`.bashrc` or `.profile` file in your home directory.

With this alias set, you can navigate directories using xplr by entering
xcd command, and when you quit by pressing enter, you will enter the
directory.

You can of course, quit with plain Quit (i.e. by pressing q) to
gracefully cancel "cd on quit".

```bash
alias xcd='cd "$(xplr --print-pwd-as-result)"'
```
