This project is a rewrite of GNU `ls` with lot of added features like colors, icons, tree-view, more formatting options etc.
The project is heavily inspired by the super [colorls](https://github.com/athityakumar/colorls) project.


## Installation

#### Prerequisites

Install the patched fonts of powerline nerd-font and/or font-awesome. Have a look at the [Nerd Font README](https://github.com/ryanoasis/nerd-fonts/blob/master/readme.md) for more installation instructions. Don't forget to setup your terminal in order to use the correct font.

### From source

With Rust's package manager cargo, you can install lsd via:

```sh
cargo install lsd
```

If you want to install the latest master branch commit:

```sh
cargo install --git https://github.com/Peltoche/lsd.git --branch master
```

### From Binaries

The [release page](https://github.com/Peltoche/lsd/releases) includes precompiled binaries for Linux, macOS and Windows for every release. You can also get the latest binary of `master` branch from the [Github action build artifacts](https://github.com/Peltoche/lsd/actions?query=branch%3Amaster+is%3Asuccess+event%3Apush) (choose the top action and scroll down to the artifacts section).

## Configuration

`lsd` can be configured with a configuration file to set the default options.
Check [Config file content](#config-file-content) for details.

### Config file location

#### Non-Windows

On non-Windows systems `lsd` follows the
[XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html)
convention for the location of the configuration file. The configuration dir
`lsd` uses is itself named `lsd`. In that directory it looks first for a file
called `config.yaml`.
For most people it should be enough to put their config file at
`~/.config/lsd/config.yaml`.

#### Windows

On Windows systems `lsd` only looks for the `config.yaml` files in one location:
`%APPDATA%\lsd\`

#### Custom

You can also provide a configuration file from a non standard location:
`lsd --config-file [PATH]`

### Config file content

This is an example config file with the default values and some additional
remarks.

```yaml
# == Classic ==
# This is a shorthand to override some of the options to be backwards compatible
# with `ls`. It affects the "color"->"when", "sorting"->"dir-grouping", "date"
# and "icons"->"when" options.
# Possible values: false, true
classic: false

# == Blocks ==
# This specifies the columns and their order when using the long and the tree
# layout.
# Possible values: permission, user, group, size, size_value, date, name, inode
blocks:
  - permission
  - user
  - group
  - size
  - date
  - name

# == Color ==
# This has various color options. (Will be expanded in the future.)
color:
  # When to colorize the output.
  # When "classic" is set, this is set to "never".
  # Possible values: never, auto, always
  when: auto
  # How to colorize the output.
  # When "classic" is set, this is set to "no-color".
  # Possible values: default, <theme-file-name>
  # when specifying <theme-file-name>, lsd will look up theme file
  # XDG Base Directory if relative, e.g. ~/.config/lsd/themes/<theme-file-name>.yaml,
  # The file path if absolute
  theme: default

# == Date ==
# This specifies the date format for the date column. The freeform format
# accepts an strftime like string.
# When "classic" is set, this is set to "date".
# Possible values: date, relative, '+<date_format>'
# `date_format` will be a `strftime` formatted value. e.g. `date: '+%d %b %y %X'` will give you a date like this: 17 Jun 21 20:14:55
date: date

# == Dereference ==
# Whether to dereference symbolic links.
# Possible values: false, true
dereference: false

# == Display ==
# What items to display. Do not specify this for the default behavior.
# Possible values: all, almost-all, directory-only
# display: all

# == Icons ==
icons:
  # When to use icons.
  # When "classic" is set, this is set to "never".
  # Possible values: always, auto, never
  when: auto
  # Which icon theme to use.
  # Possible values: fancy, unicode
  theme: fancy
  # Separator between icon and the name
  # Default to 1 space
  separator: " "

# == Ignore Globs ==
# A list of globs to ignore when listing.
# ignore-globs:
#   - .git

# == Indicators ==
# Whether to add indicator characters to certain listed files.
# Possible values: false, true
indicators: false

# == Layout ==
# Which layout to use. "oneline" might be a bit confusing here and should be
# called "one-per-line". It might be changed in the future.
# Possible values: grid, tree, oneline
layout: grid

# == Recursion ==
recursion:
  # Whether to enable recursion.
  # Possible values: false, true
  enabled: false
  # How deep the recursion should go. This has to be a positive integer. Leave
  # it unspecified for (virtually) infinite.
  # depth: 3

# == Size ==
# Specifies the format of the size column.
# Possible values: default, short, bytes
size: default

# == Permission ==
# Specify the format of the permission column
# Possible value: rwx, octal
permission: rwx

# == Sorting ==
sorting:
  # Specify what to sort by.
  # Possible values: extension, name, time, size, version
  column: name
  # Whether to reverse the sorting.
  # Possible values: false, true

symlink-arrow: ⇒

# == Header ==
# Whether to display block headers.
# Possible values: false, true
header: false
```

## Theme

`lsd` can be configured with a theme file to set the colors.

Theme can be configured in the [configuration file](#configuration)(color.theme),
The valid theme configurations are:

- `default`: the default color scheme shipped in `lsd`
- theme-file-name(yaml): use the theme file to specify colors(without the `yaml` extension)

when configured with the `theme-file-name` which is a `yaml` file,
`lsd` will look up the theme file in the following way:

- relative name: check the themes under XDG Base Directory, e.g. ~/.config/lsd/themes/<theme-file-name>.yaml
- absolute name: use the file path and name to find theme file

Check [Theme file content](#theme-file-content) for details.

### Theme file content

Theme file use the [crossterm](https://crates.io/crates/crossterm)
to configure the colors, check [crossterm](https://docs.rs/crossterm/0.20.0/crossterm/style/enum.Color.html)
for supported colors.

Color table: https://upload.wikimedia.org/wikipedia/commons/1/15/Xterm_256color_chart.svg

Please notice that color values would ignore the case, both lowercase and UPPERCASE is supported.

This is the default theme scheme shipped with `lsd`.

```yaml
user: 230
group: 187
permission:
  read: dark_green
  write: dark_yellow
  exec: dark_red
  exec-sticky: 5
  no-access: 245
  octal: 6
  acl: dark_cyan
  context: cyan
date:
  hour-old: 40
  day-old: 42
  older: 36
size:
  none: 245
  small: 229
  medium: 216
  large: 172
inode:
  valid: 13
  invalid: 245
links:
  valid: 13
  invalid: 245
tree-edge: 245
```

When creating a theme for `lsd`, you can specify any part of the default theme,
and then change its colors, the items missed would fallback to use the default colors.

Please also notice that an empty theme is **NOT** supported due to
[a bug in serde lib](https://github.com/dtolnay/serde-yaml/issues/86).

## External Configurations

### Required

Enable nerd fonts for your terminal, URxvt for example:

.Xresources

```
URxvt*font:    xft:Hack Nerd Font:style=Regular:size=11
```

### Optional

In order to use lsd when entering the `ls` command, you need to add this to your shell
configuration file (~/.bashrc, ~/.zshrc, etc.):

```sh
alias ls='lsd'
```

Some further examples of useful aliases:

```sh
alias l='ls -l'
alias la='ls -a'
alias lla='ls -la'
alias lt='ls --tree'
```

## F.A.Q

### Icons not showing up

For `lsd` to be able to display icons, the font has to include special font glyphs. This might not be the case for most fonts that you download. Thankfully, you can patch most fonts using [NerdFont](https://www.nerdfonts.com/) and add these icons. Or you can just download an already patched version of your favourite font from [NerdFont font download page](https://www.nerdfonts.com/font-downloads).
Here is a guide on how to setup fonts on [macOS](https://github.com/Peltoche/lsd/issues/199#issuecomment-494218334) and [Android](https://github.com/Peltoche/lsd/issues/423).

To check if the font you are using is setup correctly, try running the following snippet in a shell and see if that [prints a folder icon](https://github.com/Peltoche/lsd/issues/510#issuecomment-860000306). If it prints a box, or question mark or something else, then you might have some issues in how you setup the font or how your terminal emulator renders the font.

```sh
echo $'\uf115'
```

### Icons missing or not rendering correctly using PuTTY/KiTTY on Windows

First of all, make sure a patched font is installed and PuTTY/KiTTY is configurated to use it, please check [Prerequisites](#prerequisites).

There are problems for PuTTY/KiTTY to show 2 char wide icons, make sure using a 1 char wide font like [Hack Regular Nerd Font Complete Mono Windows Compatible](https://github.com/ryanoasis/nerd-fonts/blob/master/patched-fonts/Hack/Regular/complete/Hack%20Regular%20Nerd%20Font%20Complete%20Mono%20Windows%20Compatible.ttf), check [this issue](https://github.com/Peltoche/lsd/issues/331) for detail.

### Colors

You can customize filetype colors using `LS_COLORS` and other colors using the theme.

The default colors are:

| User/Group                                                            | Permission                                                                             | File Type (changes based on your terminal colorscheme)                                                  | Date                                                                                 | File Size                                                                   |

### First char of folder/file getting trimmed
Workaround for Konsole: ㅤEdit the config file (or [create it](#config-file-location) if it doesn't already exist) and paste the following into it (contains invisible unicode characters):
  ```yml
icons:
    separator: " ㅤ"
```


This is a known issue in a few terminal emulator. Try using a different terminal emulator like. [Alacritty](https://github.com/alacritty/alacritty) and [Kitty](https://github.com/kovidgoyal/kitty) are really good alternatives. You might also want to check if your font is responsible for causing this.
To verify this, try running lsd with icons disabled and if it still does not have the first character, then this is an lsd bug:

```sh
lsd --icon never --ignore-config
```

### UTF-8 Chars

`lsd` will try to display the UTF-8 chars in file name, A `U+FFFD REPLACEMENT CHARACTER`(<28>) is used to represent the invalid UTF-8 chars.
