Hyprscroller

Hyprscroller is a Hyprland layout plugin that creates a window layout similar to PaperWM. I initialy learned how to write a Hyprland plugin from hyprslidr, which is a similar idea.

The plugin is quite feature complete and supports gaps, borders, special workspace, full screen modes, overview, marks and installation through hyprpm.

I use hyprscroller on my main machine and will support it for as long as I keep on using Hyprland. However, I will only add new features that I find interesting, and support two Hyprland versions: the one my distribution uses, and the latest tagged one. I have found problematic compiling trunk versions of Hyprland on a system that already has a system-wide version of it installed, so I will not make an extra effort there until things improve in that front.

Requirements

hyprscroller supports the version of Hyprland I use, which should be the same as the Arch Linux hyprland package. You can try your luck with the latest git changes, but I will be slower to keep up with those, as there are too many API changes going on upstream.

Aside from those versions, even though the feature set will be frozen for them, hyprscroller also supports v0.35, v0.38.1, v0.39.1 and v0.40.0.

Building and installing

With Hyprland installed it should be as simple as running

# builds a shared object hyprscroller.so
make all
# installs the shared library in ~/.config/hypr/plugins
make install

A more automated mode is to use hyprpm.

hyprpm add https://github.com/dawsers/hyprscroller
# verify it installed correctly
hyprpm list

You can enable or disable it via hyprpm enable hyprscroller and hyprpm disable hyprscroller.

Configuration

If you are not using hyprpm, to make Hyprland load the plugin, add this to your configuration.

plugin = ~/.config/hypr/plugins/hyprscroller.so

Instead, if you use hyprpm, it should be as simple as adding this to your ~/.config/hypr/hyprland.conf :

exec-once = hyprpm reload -n

To turn on the layout, use

general {
    ...

    layout = scroller

    ...
}

Dispatchers

The plugin adds the following dispatchers:

Dispatcher	Description
`scroller:movefocus`	A replacement for `movefocus`, takes a direction as argument.
`scroller:movewindow`	A replacement for `movewindow`, takes a direction as argument.
`scroller:setmode`	Set mode: `r/row` (default), `c/col/column`. Sets the working mode. Affects most dispatchers and new window creation.
`scroller:cyclesize`	Resize the focused column width (row mode), or the active window height (column mode).
`scroller:alignwindow`	Align window on the screen, `l/left`, `c/center`, `r/right` (row mode), `c/center`, `u/up`, `d/down` (col mode)
`scroller:admitwindow`	Push the current window below the active one of the column to its left.
`scroller:expelwindow`	Pop the current window out of its column and place it on a new column to the right.
`scroller:fitsize`	Resize columns (row mode) or windows (col mode) so they fit on the screen: `active`, `visible`, `all`, `toend`, `tobeg`
`scroller:toggleoverview`	Toggle an overview of the workspace where all the windows are temporarily scaled to fit the monitor
`scroller:marksadd`	Add a named mark. Argument is the name of the mark
`scroller:marksdelete`	Delete a named mark. Argument is the name of the mark
`scroller:marksvisit`	Visit a named mark. Argument is the name of the mark
`scroller:marksreset`	Delete all marks

Modes

Hyprscroller works in any of two modes that can be changed at any moment.

row mode: it is the default. It creates new windows in a new column. cyclesize affects the width of the active column. alignwindow aligns the active column according to the argument received. fitsize fits the selected columns to the width of the monitor.
column mode: It creates new windows in the current column, right below the active window. cyclesize affects the height of the active window. alignwindow aligns the active window within the column, according to the argument received. fitsize fits the selected windows in the column to the height of the monitor.

Window/Column Focus and Movement

If you want to use Hyprscroller you will need to map your key bindings from the default movefocus/movewindow to scroller:movefocus/scroller:movewindow. The reason is Hyprland doesn't have the concept (yet) of a workspace that spans more than the space of a monitor, and when focusing directionally, it doesn't look for windows that are "outside" of that region. If this changes in the future, these two dispatches may become obsolete.

movefocus and movewindow accept the following directional arguments: l or left, r or right, u or up, d or dn or down, b or begin or beginning, e or end. So you can focus or move windows/columns in a direction or to the beginning or end or the row.

Resizing

cyclesize accepts an argument which is either +1/1/next, or -1/prev/previous. It cycles forward or backward through three column widths (in row mode): one third, one half or two thirds of the available width of the monitor. In column mode, the fractions are relative to the height of the monitor, and are: one third, one half, two thirds or one. However, using resizewindow, you can modify the width or height of any window freely.

Aligning

Columns are generally aligned in automatic mode, always making the active one visible, and trying to make at least the previously focused one visible too if it fits the viewport, if not, the one adjacent on the other side. However, you can always align any column to the center, left or right of the monitor (in row mode), or up (top), down (bottom) or to the center in column mode. For example center a column for easier reading, regardless of what happens to the other columns. As soon as you change focus or move a column, the alignment is lost.

alignwindow takes a parameter: l or left, r or right, c or center or centre, u or up and d or down.

To use right or left you need to be in row mode, and to use up or down in column mode. center behaves differently depending on the mode. In row mode it aligns the active column to the center of the monitor. In column mode, it aligns the active window within its column, to a centered position.

Admit/Expel

You can create columns of windows using admitwindow. It takes the active window and moves it to the column left of its current one, right under the active window in that column.

To expel any window from its current column and position it in a new column to its right, use expelwindow.

Fitting the Screen

When you have a ultra-wide monitor, one in a vertical position, or the default column widths or window heights don't fit your workflow, you can use manual resizing, but it is sometimes slow and tricky.

scroller:fitsize works in two different ways, depending on the active mode.

It allows you to re-fit the columns (row mode) or windows (column mode) you want to the screen extents. It accepts an argument related to the columns/windows it will try to fit. The new width/height of each column/window will be proportional to its previous width or height, relative to the other columns or windows affected.

active: It is similar to maximize, it will fit the active column/window.
visible: All the currently fully or partially visible columns/windows will be resized to fit the screen.
all: All the columns in the row or windows in the column will be resized to fit.
toend: All the columns or windows from the focused one to the end of the row/column will be affected.
tobeg or tobeginning: All the columns/windows from the focused one to the beginning of the row/column will now fit the screen.

Overview

scroller:toggleoverview toggles a bird's eye view of the current workspace where all the windows are scaled to fit the current monitor. You can still interact with them normally (change focus, move windows, type in them etc.). When toggling back to normal mode, the original window sizes will be restored...so it is not wise to use toggleoverview for window resizing or creating new windows. Use it as a way to see where things are and move the active focus, or a window, anything beyond that will probably find bugs or cause compositor crashes.

Marks

You can use marks to navigate to frequently used windows, regardless of which workspace they are in (it even works for the special workspace windows).

scroller:marksadd adds a named mark. Use a submap to create bindings for several named marks you may want to use. See the configuration example for directions.

scroller:marksdelete deletes a named mark created with scroller:marksadd.

scroller:marksvisit moves the focus to a previously created mark.

scroller:marksreset clears all marks.

Marks reference windows, but are global, they may belong to different workspaces, so visiting a mark may switch workspaces.

You can use any string name for a mark, for example in scripts. But they are also very convenient to use with regular key bindings by simply using a letter as the name. Again, see the example configuration.

Options

hyprscroller currently accepts the following options:

column_default_width: determines the width of new columns in row mode. Possible arguments are: onehalf (default), onethird, twothirds, maximized, floating (uses the default width set by the application).
focus_wrap: determines whether focus will wrap when at the first or last window of a row/column. Possible arguments are: true|1 (default), or false|0.

For example:

plugin {
    scroller {
        column_default_width = onehalf
        focus_wrap = false
    }
}

Key bindings

As an example, you could set some key bindings in your hyprland.conf like this:

# Move focus with mainMod + arrow keys
bind = $mainMod, left, scroller:movefocus, l
bind = $mainMod, right, scroller:movefocus, r
bind = $mainMod, up, scroller:movefocus, u
bind = $mainMod, down, scroller:movefocus, d
bind = $mainMod, home, scroller:movefocus, begin
bind = $mainMod, end, scroller:movefocus, end
