        # zsh-lux

**zsh-lux**, a zsh plugin to toggle the light & dark modes of macOS and other items and applications via the `lux` command. Highly customizable: included items can be configured by defining variables. Highly extensible: items can be added by defining functions.

Also features the `macos_is_dark` helper function to determine if the macOS dark mode (in 10.14+) is active, for example to handle terminal theming.

### Usage

#### `lux`

Switch to/activate the mode (i.e `light`, `dark`) of macOS or of another item.

`lux  ` 

Example usage:

```bash

lux macos dark

lux macos light

lux iterm light

# ...

```

#### `macos_is_dark`

Helper function that checks if the dark mode in macOS is active.

* Returns:

  * `0` if dark mode is active

  * `1` if light mode is active

  * `2` if the status of the dark mode can't be determined (i.e. the version of macOS does not support it)

Example usage:

```bash

if macos_is_dark; then

    echo "macOS is dark!"

else

    echo "macOS is light!"

fi

```

#### `macos_release_name`

Helper function that returns the capitalized release name of macOS (e.g. "Monterey")

Example usage:

```bash

$ sw_vers -productVersion

12.6

$ macos_release_name

Monterey

```

#### Debug mode

Set `LUX_DEBUG=1` to get a log output for debuging purposes.

### Items

An item is represented by one function that can trigger an appearance change for that item. These functions take an argument (e.g. the name of a theme) which are retrieved from a variable which name's depends on the chosen mode (i.e. `light`, `dark`).  These variables follow the convention `LUX__`. In most cases, these variables can be redefined (e.g. in `.zshrc`).

#### `macos`

**Action**: Sets macOS dark mode

**Requires**: macOS

**Modes**:

| Mode    | Variable          | Default | Customizable |

| ------- | ----------------- | ------- | ------------ |

| `light` | `LUX_MACOS_LIGHT` | `false` | 🚫            |

#### `macos_desktop`

**Action**: Sets macOS desktop picture. On Mojave and above, _Dynamic_ and _Light and Dark_ Desktop pictures are special `.heic` files that contain multiple images that macOS can [automatically change throughout the day](https://support.apple.com/en-ca/guide/mac-help/mchlp3013/12.0/mac/12.0). For those desktop pictures, set the same path for both `light` and `dark` and use [macos_desktop_style](#macos_desktop_style) to choose the appearance setting.

*Note:* Only the ` Graphic.heic` (e.g. `Ventura Graphic.heic`) Dynamic Desktop comes pre-installed. To use other images than the default (below), select the image in System Preferences which will download it to `~/Library/Application Support/com.apple.mobileAssetDesktop/`

**Requires**: macOS

**Modes**:

| Mode    | Variable                  | Default                                                      | Customizable |

| ------- | ------------------------- | ------------------------------------------------------------ | ------------ |

| `light` | `LUX_MACOS_DESKTOP_LIGHT` | `/System/Library/Desktop Pictures/ Graphic.heic` | ✅            |

**Extra configuration**: N/A

---

#### `macos_desktop_style`

**Action**: Sets macOS desktop picture _style_, for certain `.heic` images (in Mojave and above) that support it. Supported image types are either "Dynamic Desktop" (`dynamic`, image changes throughout the day) or "Light and Dark" (`auto`, image matches the macOS apperance). Either types can be expliclty set to their `light` or `dark` setting).

**Requires**: macOS

**Modes**:

| Mode      | Variable                          | Default   | Customizable |

| `dark`    | `LUX_MACOS_DESKTOP_STYLE_DARK`    | `dark`    | 🚫            |

| `auto`    | `LUX_MACOS_DESKTOP_STYLE_AUTO`    | `auto`    | 🚫            |

### Extending `zsh-lux`

`zsh-lux` is convention-based and can therefore be easily expanded. See the plugin file for examples.

#### Adding items

Better explained with an example: let's pretend we want to add an item for an application called 'wow' that reads its theme name in `/tmp/wow.cfg`. 'wow' is in light mode when the theme is '*white*' and in dark mode when the theme is '*black*':

1. Define a function named `_lux_set_`  that sets theme name in `/tmp/wow.cfg` from an argument `$1`:

   ```bash

   function _lux_set_wow() {

     echo "$1" > /tmp/wow.cfg

   }

   ```

2. Define `LUX__` for the modes:

   ```bash

   LUX_WOW_LIGHT='white'

   LUX_WOW_DARK='black'

   ```

**Done!** Now just call:

```bash

lux wow light # or

lux wow dark

```

This new item will also be automatically be added to zsh's tab autocompletion.

#### Adding modes

By default, items have a `light` and `dark` mode, but adding other modes is a simple as defining a new variable.

For example to add the modes `superhero` (that sets the [`batman`](https://github.com/mbadolato/iTerm2-Color-Schemes#batman) iTerm colour scheme) and `purple` (that sets the [`c64`](https://github.com/mbadolato/iTerm2-Color-Schemes#c64) iTerm2 colour scheme), define `LUX__` for each:

```bash

LUX_ITERM_SUPERHERO="batman"

LUX_ITERM_PURPLE="c64"

```

**Done!** Now just call:

```bash

lux iterm superhero

lux iterm purple

```

*(Optional)* To add those extra modes to the tab autocompletion, define the `LUX__EXTRAS` variable with space-delimited values of those extra modes:

```bash

LUX_ITERM_EXTRAS="superhero purple"

```

### Caveats / known issues

#### macOS Sonoma (14)

* Using certain HEIF images as desktop picture will cause `macos_desktop_style` to sometimes reset the desktop picture to the system default, Sonoma Horizons (the vineyard photo).

  (This is the case of `System/Library/Desktop Pictures/Sonoma.heic` which is the default used by `macos_desktop` when on Sonoma.)

  **Workaround:** Don't use `macos_desktop_style` with these images. When setting `Sonoma.heic` or any other troublesome image, the image acts as if `macos_desktop_style` was set to  `auto` , i.e. the light/dark of the image will follow the system appearance.

  To use the `all` item, override the `LUX_ALL_LIST` in your shell config to skip `macos_desktop_style` , e.g. `LUX_ALL_LIST=( macos macos_desktop iterm_all vscode )`
