| Arch Linux | `pacman -S felix-rs`  | The binary name is `felix` if you install via pacman. Alias `fx='felix'` if you want, as this document (and other installations) uses `fx`. |

### From this repository

- Make sure that `gcc` is installed.
- MSRV(Minimum Supported rustc Version): **1.78.0**

Update Rust if rustc < 1.78.0:

```
rustup update
```

```
git clone https://github.com/kyoheiu/felix.git
cd felix
cargo install --path .
```

<a id="integrations"></a>

## Integrations

### Exit to last working directory (LWD)
To export your LWD to the calling shell after exiting from `fx`,
add the following to your `.bashrc` or
`.zshrc` or an equivalent depending on your (POSIX) shell.  
***Assuming the `fx` binary can be found in your `PATH`.***

```sh
source <(command fx --init)
```

*If this is not set, exiting to LWD will fail and show the error message.*

### Others
In addition, you can use felix more conveniently by installing these apps:

- [zoxide](https://github.com/ajeetdsouza/zoxide): A smarter `cd` command, which
  enables you to jump to a directory that matches the keyword in felix.
- [chafa](https://hpjansson.org/chafa/): Terminal graphics for the 21st century,
  by which you can preview images in felix. _**chafa must be v1.10.0 or
  later.**_
- [bat](https://github.com/sharkdp/bat): A *cat(1)* clone. Add syntax highlighting to the text preview with bat.

These apps do not need any configuration to use with felix!

<a id="usage"></a>

## Usage

_If you install this app via pacman, the default binary name is `felix`._

```
`fx` => Show items in the current directory.
`fx <directory path>` => Show items in the directory.
Both relative and absolute path available.
```

### Options

```
`--help` | `-h` => Print help.
`--log`  | `-l` => Launch the app, automatically generating a log file in `{data_local_dir}/felix/log`.
`--init`        => Returns a shell script that can be sourced for shell integration.
```

## Preview feature

By default, text files and directories can be previewed by pressing `v`.\
Install `chafa` and you can preview images as well.

<a id="configuration"></a>

## Configuration

### Config file

If any config file is not found, or found one is broken, felix launches with the default configuration, without creating new one.
Note that the default editor is `$EDITOR`, so if you've not set it, opening a file will fail.
You can find default config file (`config.yaml`) in this repository.

*Both `config.yaml` and `config.yml` work from v2.7.0*

### Trash directory and log file

Contrary to the config file, these directory and file will be automatically created.

### Linux

```
config file     : $XDG_CONFIG_HOME/felix/config.yaml(config.yml)
trash directory : $XDG_DATA_HOME/felix/Trash
log files       : $XDG_DATA_HOME/felix/log
```

### macOS

On macOS, felix looks for the config file in the following locations:

1. `$HOME/Library/Application Support/felix/config.yaml(config.yml)`
2. `$HOME/.config/felix/config.yaml(config.yml)`

```
trash directory : $HOME/Library/Application Support/felix/Trash
log files       : $HOME/Library/Application Support/felix/log
```

### Windows

```
config file     : $PROFILE\AppData\Roaming\felix\config.yaml(config.yml)
trash directory : $PROFILE\AppData\Local\felix\Trash
log files       : $PROFILE\AppData\Local\felix\log
```

### About `Rgb` and `AnsiValue`
You can configure these colors like this:
```
color:
  dir_fg: LightCyan
  file_fg: !AnsiValue 120
  symlink_fg: LightYellow
  dirty_fg: !Rgb [124, 30, 40]
```
