---

hyprlock is a simple, yet fast, multi-threaded and GPU-accelerated screen lock
for Hyprland.

## Configuration

Configuration is done via the config file at `~/.config/hypr/hyprlock.conf`. It
is not required, but recommended. Without it, locking shows the current screen.

### Variable types

Hyprlock uses the following types in addition to [Hyprland's variable types](../../Configuring/Variables#Variable_types).

| type | description |
| -- | -- |
| layoutxy | vec2 with an optional `%` suffix, allowing users to specify sizes as percentages of the output size. Floats (e.g. 10.5) are supported, but only have an effect when used with `%`. Raw pixel values will just get rounded. |

### General

Variables in the `general` category:

| variable | description | type | default |
| -- | -- | -- | -- |
| disable_loading_bar | disables the loading bar on the bottom of the screen while hyprlock is booting up. | bool | false |
| hide_cursor | hides the cursor instead of making it visible | bool | false |
| grace | the amount of seconds for which the lockscreen will unlock on mouse movement. | int | 0 |
| no_fade_in | disables the fadein animation | bool | false |
| no_fade_out | disables the fadeout animation | bool | false |
| ignore_empty_input | skips validation when no password is provided | bool | false |
| immediate_render | makes hyprlock immediately start to draw widgets. Backgrounds will render `background:color` until their `background:path` resource is available | bool | false |
| text_trim | sets if the text should be trimmed, useful to avoid trailing newline in commands output | bool | true |
| fractional_scaling | whether to use fractional scaling. 0 - disabled, 1 - enabled, 2 - auto | int | 2 |

{{< callout type=warning >}}

If you are not on hyprland, or your `XDG_CURRENT_DESKTOP` is not Hyprland, the fade out will be disabled and the value of your `no_fade_out` variable will be ignored.

{{< /callout >}}

### Authentication

Variables in the `auth` category:

| variable | description | type | default |
| -- | -- | -- | -- |
| pam:enabled | whether to enable pam authentication | bool | true |
| pam:module | sets the pam module used for authentication. If the module isn't found in `/etc/pam.d`, "su" will be used as a fallback | str | hyprlock |
| fingerprint:enabled | enables parallel fingerprint auth with fprintd. | bool | false |
| fingerprint:ready_message | sets the message that will be displayed when fprintd is ready to scan a fingerprint. | str | (Scan fingerprint to unlock) |
| fingerprint:present_message | sets the message that will be displayed when a finger is placed on the scanner. | str | Scanning fingerprint |

{{< callout type=info >}}

At least one enabled authentication method is required.

## Keyboard Shortcuts and Actions

The following keys and key-combinations describe hyprlock's default behaviour:

| input | description |
| -- | -- |
| ESC | Clear password buffer |
| Ctrl + u | Clear password buffer |
| Ctrl + Backspace | Clear password buffer |

## Widgets

The entire configuration of how hyprlock looks is done via widgets.

```ini
widget_name {
    monitor =
    # further options
}
```

`monitor` can be left empty for "all monitors"

## Widget List

### General remarks

- All rendered text supports
  [pango markup](https://docs.gtk.org/Pango/pango_markup.html).
  - Additionally hyprlock will parse `<br/>` for your convenience. (That's a
    linebreak) Remember to enable linebreaks in your spans with
    `allow_breaks="true"`.
- Positioning is done via halign, valign, position, and zindex. Position is an added
  offset to the result of alignment.
  - halign: `left`, `center`, `right`, `none`. valign: `top`, `center`,
    `bottom`, `none`
  - zindex: Widgets with larger numbers will be placed above widgets with smaller numbers. All widgets default to 0, except background which defaults to -1.
- All `position` and `size` options can be specified in pixels or as percentages of the output size.
  - pixels: `10, 10` or `10px, 10px`
  - percentages: `10%, 10.5%`
  - mixed: `10%, 5px`
- Supported image formats are png, jpg and webp (no animations though)

### Shadowable

Some widgets are shadowable, meaning they can have a shadow. For those widgets, you get:

| variable | description | type | default |
| -- | -- | -- | -- |
| shadow_passes | passes for shadow, 0 to disable | int | 0 |
| shadow_size | size for shadow | int | 3 |
| shadow_color | shadow color | color | rgb(0,0,0) |
| shadow_boost | boost shadow's opacity | float | 1.2 |

### Background

Draws a background image or fills with color.

If `path` is empty or missing, will use `color`. Otherwise, the image will be
used.

If `path` is `screenshot`, a screenshot of your desktop at launch will be used.

| vibrancy | Increase saturation of blurred colors | float | 0.1696 |
| vibrancy_darkness | How strong the effect of vibrancy is on dark areas | float | 0.05 |
| reload_time | seconds between reloading, 0 to reload with SIGUSR2. Ignored if `path` is `screenshot`. | int | -1 |
| reload_cmd | command to get new path. If empty, old path will be used. | str | [[Empty]] |
| crossfade_time | cross-fade time in seconds between old and new background on reload. A negative value means no cross-fade. | float | -1.0 |
| zindex | z-index of the widget | int | -1 |

{{< callout type=info >}}

#### Colors information

When `outline_thickness` set to `0`, the color of the inner box will be changed instead of the outer.

Behaviour of `swap_font_color` is as follows:

- `outline_thickness` is `0`: if set, font color will be swapped with inner one on color change events (e.g. Caps-lock on or password check).
- `outline_thickness` is not `0`: if set, font and inner colors will be swapped on password check and authentication failure.
- `swap_font_color` will narrow the accent colors from a gradient to a single color by using the first specified color.

{{< /callout >}}

Available variables for `placeholder_text`:

- `$PROMPT` - prompt text provided by pam. Usually this will be "Password: ", but it depends on your pam configuration.

Available variables for `fail_text`:

- `$FAIL` - pam fail reason
- `$ATTEMPTS` - number of failed authentication attempts

{{% details title="Example input-field" closed="true" %}}

```ini
input-field {
    monitor =
    size = 20%, 5%
    outline_thickness = 3
    inner_color = rgba(0, 0, 0, 0.0) # no fill

    outer_color = rgba(33ccffee) rgba(00ff99ee) 45deg
    check_color=rgba(00ff99ee) rgba(ff6633ee) 120deg
    fail_color=rgba(ff6633ee) rgba(ff0066ee) 40deg

    font_color = rgb(143, 143, 143)
    fade_on_empty = false
    rounding = 15

    position = 0, -20
    halign = center
    valign = center
}
```

### Label

&check; Shadowable

Draws a label.

| variable | description | type | default |
|--|--|--|--|
| monitor | monitor to draw on | str | [[Empty]] |
| text | text to render | str | Sample Text |
| text_align | multi-line text alignment inside label container. center/right or any value for default left. | str | center |
| color | color of the text | color | rgba(254, 254, 254, 1.0) |
| font_size | size of the font | int |16 |
| font_family | font family | str | Sans |
| rotate | rotation in degrees, counter-clockwise | int | 0 |
| position | position of the label | layoutxy | 0, 0 |
| halign | horizontal alignment | str | center |
| valign | vertical alignment | str | center |

Available variables for `text`:

- `$USER` - username (e.g. linux-user)
- `$DESC` - user description (e.g. Linux User)
- `$TIME` - current time in 24-hour format (e.g. `13:37`)
- `$TIME12` - current time in 12-hour format (e.g. `1:37 PM`)
- `$PROMPT` - last pam prompt
- `$FAIL` - last pam fail reason
- `$ATTEMPTS` - failed attempts
- `$LAYOUT` - current keyboard layout
- `$FPRINTMESSAGE` - last message from fingerprint matching

`text` also supports launching commands, for example:

```ini
text = cmd[update:1000] echo "<span foreground='##ff2222'>$(date)</span>"
```

Worth noting:

- `update:` - time is in ms.
- label can be forcefully updated by specifying `update:<time>:1` or `update:<time>:true` and sending `SIGUSR2` to hyprlock. `<time>` can be `0` in this case.
- `$ATTEMPTS[<string>]` format can be used to show `<string>` when there are no failed attempts. You can use pango-markup here. `<string>` can be empty to hide.
- `$LAYOUT[<str0>,<str1>,...]` format is available to replace indexed layouts. You can use settings from `hyprland.conf`, e.g. `$LAYOUT[en,ru,de]`. Also, single `!` character will hide layout. E.g. `$LAYOUT[!]` will hide default (0 indexed) and show others.
- Variables seen above are parsed _before_ the command is ran.
- **do not** run commands that never exit. This will hang the AsyncResourceGatherer and you won't have a good time.

## User Signals

- `SIGUSR1` - unlocks hyprlock. For example, you can switch to a another tty and run `pkill -USR1 hyprlock`.
- `SIGUSR2` - updates labels and images. See above.
