Custom

Allows you to compose custom modules consisting of multiple widgets, including popups. Labels can display dynamic content from scripts, and buttons can interact with the bar or execute commands on click.

Configuration

Type: custom

This module can be quite fiddly to configure as you effectively have to build a tree of widgets by hand. It is well worth looking at the examples.

Name	Type	Default	Description
class	string	null	Container class name.
bar	Widget[]	null	List of widgets to add to the bar.
popup	Widget[]	[]	List of widgets to add to the popup.

Widget

Name	Type	Default	Description
widget_type	box or label or button or image	null	Type of GTK widget to create.
name	string	null	Widget name.
class	string	null	Widget class name.
label	string	null	[label and button] Widget text label. Pango markup supported.
on_click	string	null	[button] Command to execute. More on this below.
src	image	null	[image] Image source. See here for information on images.
size	integer	null	[image] Width/height of the image. Aspect ratio is preserved.
orientation	horizontal or vertical	horizontal	[box] Whether child widgets should be horizontally or vertically added.
widgets	Widget[]	[]	[box] List of widgets to add to this box.

Labels

Labels can interpolate text from scripts to dynamically show content. This can be done by including scripts in {{double braces}} using the shorthand script syntax.

For example, the following label would output your system uptime, updated every 30 seconds.

Uptime: {{30000:uptime -p | cut -d ' ' -f2-}}

Both polling and watching mode are supported. For more information on script syntax, see here.

Commands

Buttons can execute commands that interact with the bar, as well as any arbitrary shell command.

To execute shell commands, prefix them with an !. For example, if you want to run ~/.local/bin/my-script.sh on click, you'd set on_click to !~/.local/bin/my-script.sh.

The following bar commands are supported:

• popup:toggle
• popup:open
• popup:close

---

XML is arguably better-suited and easier to read for this sort of markup, but currently is not supported. Nonetheless, it may be worth comparing the examples to the below equivalent to help get your head around what's going on:

<?xml version="1.0" encoding="utf-8" ?>
<custom class="power-menu">
    <bar>
        <button name="power-btn" label="" on_click="popup:toggle"/>
    </bar>
    <popup>
        <box orientation="vertical">
            <label name="header" label="Power menu" />
            <box>
                <button class="power-btn" label="" on_click="!shutdown now" />
                <button class="power-btn" label="" on_click="!reboot" />
            </box>
            <label name="uptime" label="Uptime: {{30000:uptime -p | cut -d ' ' -f2-}}" />
        </box>
    </popup>
</custom>

Styling

Since the widgets are all custom, you can target them using #name and .class.
