# Waybar

Waybar is a GTK status bar made specifically for wlroots compositors.

To use it, it's recommended to use your distro's package by searching `waybar-hyprland`.

## Compiling Manually

To compile manually:

Clone the source, cd into it, then do:

```bash
sed -i -e 's/zext_workspace_handle_v1_activate(workspace_handle_);/const std::string command = "hyprctl dispatch workspace " + name_;\n\tsystem(command.c_str());/g' src/modules/wlr/workspace_manager.cpp
meson --prefix=/usr --buildtype=plain --auto-features=enabled --wrap-mode=nodownload build
meson configure -Dexperimental=true build
sudo ninja -C build install
```

If you want to use the workspaces module, first, copy the configuration files from
`/etc/xdg/waybar/` into `~/.config/waybar/`. Then, in `~/.config/waybar/config` replace
all the references to `sway/workspaces` with `wlr/workspaces`.

For more info regarding configuration, see
[The Waybar Wiki](https://github.com/Alexays/Waybar/wiki).

## Waybar popups render behind the windows

In `~/.config/waybar/config`, make sure that you have the `layer` configuration
set to `top` and not `bottom`.

## Active workspace doesn't show up

Replace `#workspaces button.focused` with `#workspaces button.active` in `~/.config/style.css`.

## Scrolling through workspaces

Since there a lot of configuration options from `sway/workspaces` are missing, you
should deduce some of them by yourself. In the case of scrolling, it should look like this:

```json
"wlr/workspaces": {
     "format": "{icon}",
     "on-scroll-up": "hyprctl dispatch workspace e+1",
     "on-scroll-down": "hyprctl dispatch workspace e-1"
}
```

## Clicking on a workspace icon does not work!

On the `wlr/workspaces` module, add `"on-click": "activate"`. That's the purpose of
the `sed` command used before building Waybar: the default way to select a workspace by 
clicking uses the `swaymsg`'s way, and thus it is required to edit
this function to make it work with `hyprctl`.

# Eww

In order to use [Eww](https://github.com/elkowar/eww), you first have to install
it, either using your distro's package manager, by searching `eww-wayland`, or
by manually compiling. In the latter case, you can follow the
[instructions](https://elkowar.github.io/eww).

## Configuration

After you've successfully installed Eww, you can move onto configuring it. There
are a few examples listed in the [Readme](https://github.com/elkowar/eww). It's also
highly recommended to read through the
[Configuration options](https://elkowar.github.io/eww/configuration.html).

{{< hint type=important >}}
Read
[the Wayland section](https://elkowar.github.io/eww/configuration.html#wayland)
carefully before asking why your bar doesn't work.
{{< /hint >}}

Here are some example widgets that might be useful for Hyprland:

<details>
<summary>Workspaces widget</summary>

This widget displays a list of workspaces 1-10. Each workspace can be clicked on to jump to it, and scrolling over the widget cycles through them. It supports different styles for the current workspace, occupied workspaces, and empty workspaces. It requires [bash](https://linux.die.net/man/1/bash), [awk](https://linux.die.net/man/1/awk), [stdbuf](https://linux.die.net/man/1/stdbuf), [grep](https://linux.die.net/man/1/grep), [seq](https://linux.die.net/man/1/seq), [socat](https://linux.die.net/man/1/socat), [jq](https://stedolan.github.io/jq/), and [Python 3](https://www.python.org/).

### `~/.config/eww.yuck`

```lisp
...
(deflisten workspaces :initial "[]" "bash ~/.config/eww/scripts/get-workspaces")
(deflisten current_workspace :initial "1" "bash ~/.config/eww/scripts/get-active-workspace")
(defwidget workspaces []
  (eventbox :onscroll "bash ~/.config/eww/scripts/change-active-workspace {} ${current_workspace}" :class "workspaces-widget"
    (box :space-evenly true
      (label :text "${workspaces}${current_workspace}" :visible false)
      (for workspace in workspaces
        (eventbox :onclick "hyprctl dispatch workspace ${workspace.id}"
          (box :class "workspace-entry ${workspace.id == current_workspace ? "current" : ""} ${workspace.windows > 0 ? "occupied" : "empty"}"
            (label :text "${workspace.id}")
            )
          )
        )
      )
    )
  )
...

```

### `~/.config/eww/scripts/change-active-workspace`

```sh
#! /bin/bash
function clamp {
	min=$1
	max=$2
	val=$3
	python -c "print(max($min, min($val, $max)))"
}

direction=$1
current=$2
if test "$direction" = "down"
then
	target=$(clamp 1 10 $(($current+1)))
	echo "jumping to $target"
	hyprctl dispatch workspace $target
elif test "$direction" = "up"
then
	target=$(clamp 1 10 $(($current-1)))
	echo "jumping to $target"
	hyprctl dispatch workspace $target
fi
```

### `~/.config/eww/scripts/get-active-workspace`

```sh
#!/bin/bash
hyprctl monitors -j | jq --raw-output .[0].activeWorkspace.id
socat -u UNIX-CONNECT:/tmp/hypr/$HYPRLAND_INSTANCE_SIGNATURE/.socket2.sock - | stdbuf -o0 awk -F '>>|,' '/^workspace>>/{print $2}'
```

### `~/.config/eww/scripts/get-workspaces`

```sh
#!/bin/bash

spaces (){
	WORKSPACE_WINDOWS=$(hyprctl workspaces -j | jq 'map({key: .id | tostring, value: .windows}) | from_entries')
	seq 1 10 | jq --argjson windows "${WORKSPACE_WINDOWS}" --slurp -Mc 'map(tostring) | map({id: ., windows: ($windows[.]//0)})'
}

spaces
socat -u UNIX-CONNECT:/tmp/hypr/$HYPRLAND_INSTANCE_SIGNATURE/.socket2.sock - | while read -r line; do
	spaces
done
```

</details>

<details>
<summary>Active window title widget</summary>

This widget simply displays the title of the active window. It requires [awk](https://linux.die.net/man/1/awk), [stdbuf](https://linux.die.net/man/1/stdbuf), [socat](https://linux.die.net/man/1/socat), and [jq](https://stedolan.github.io/jq/).

### `~/.config/eww/eww.yuck`

```lisp
...
(deflisten window :initial "..." "sh ~/.config/eww/scripts/get-window-title")
(defwidget window_w []
  (box
    (label :text "${window}"
    )
  )
...
```

### `~/.config/eww/scripts/get-window-title`

```sh
#!/bin/sh
hyprctl activewindow -j | jq --raw-output .title
socat -u UNIX-CONNECT:/tmp/hypr/$HYPRLAND_INSTANCE_SIGNATURE/.socket2.sock - | stdbuf -o0 awk -F '>>|,' '/^activewindow>>/{print $3}'
```

# Hybrid

Like Waybar, [Hybrid](https://github.com/vars1ty/HybridBar) is a GTK status bar mainly focused for wlroots compositors.

You can install it from the AUR by the name `hybrid-bar`.

## Configuration

The configuration is done through JSON, more information is available [here](https://github.com/vars1ty/HybridBar).

### Blur

To activate blur, set `blurls=NAMESPACE` in your hyprland configuration, where `NAMESPACE` is the gtk-layer-shell namespace of your HybridBar. The default namespace is `gtk-layer-shell` and can be changed in the HybridBar configuration at 
```json
{
     "hybrid" {
          "namespace": "namespace name"
     }
}
```
