Configuration

The parameters on this page are using the default values unless stated otherwise. If the key is undefined (commented out) or its value is empty, it means there is no default value for the given parameter.

Configuration Syntax

The configuration uses the INI file format, the full specification can be found here.

[section/name]
str = My string
bool = true
bool = on
int = 10
float = 10.0

; Quote string values if you want to keep surrounding spaces
str = "   My string"

; Lists are defined using a 0-based index
mylist-0 = value
mylist-1 = value
mylist-2 = value
; Lists cannot have gaps. To define mylist-4 
; you will also have to define mylist-3

Referencing values

; You can reference a value in another section using:
key = ${section.key}

; Values in the same section can be referenced using:
key = ${self.key}

; Values for a defined bar can be referenced using:
key = ${bar/top.foreground}

; Values for the current bar can be referenced using:
key = ${root.foreground}

; Environment variables can be referenced using:
key = ${env:VAR:fallback value}

; Values in the X resources db can be referenced using:
; NOTE: Requires `+xrm` (compiled with `xcb-util-xrm` dependency)
; Example: 
; Polybar config:
;     background = ${xrdb:color2:#00ff00}
; .Xresources:
;     *color2: #8C9440
key = ${xrdb:KEY:fallback value}

; File contents can be referenced using:
key = ${file:/absolute/file/path:fallback value}

Note: References can only be used on their own. That means something like key = text ${section.key} text will not work (the reference will not be resolved).

Inheritance

Values can be inherited from another section by defining the parameter inherit = section/base. All undefined keys will be cloned.

[section/base]
foo = 1
bar = 0.15
baz = true

[section/child]
inherit = section/base
baz = false

; Result
[section/child]
foo = 1
bar = 0.15
baz = false

Multiple sections can be inherited by adding multiple space separated section names to the inherit key: inherit = section1 section2.

File inclusion

It is possible to include a file or all files in a directory with pre-defined key-value pairs using:

include-file = /absolute/path/to/file
include-directory = /absolute/path/to/directory
; Relative paths are new in version 3.6.0
include-file = relative/path/to/file
include-directory = relative/path/to/directory

This is equivalent to replacing the include-file directive with the contents of the file.

The include-directory directive will include all files in the given directory (non-recursively) the same way as multiple include-file directives. Files are included in alphabetical order.

Note: The files included that way can also contain further include-file and include-directory keys. Make sure that you do not create a cycle where a file includes itself directly or indirectly.

Multiple include directives can be defined inside a section because they are not proper config keys.

When specifying a relative path, the path is taken relative to the file where the include directive is defined.

Custom variables

; You can create your own local variables, for example:
[colors]
black = #000
white = #fff
blue = #00f
green = #0f0

[modules/tmp]
format-background = ${colors.black}
format-foreground = ${colors.white}

Using the same module for multiple bars

If you are using the same module for more than one bar, there's a neat way to make bar specific changes to the module configuration. Define some custom parameters, for both bars, and then reference them from the module. For example:

[bar/top]
myscript-background = #f00
myscript-command = whoami

[bar/bottom]
myscript-background = #f00
myscript-command = date +%s

[module/myscript]
format-background = ${root.myscript-background}
exec = ${root.myscript-command}

Bar settings

Each bar you want to display needs a so called "bar section". The bar section is defined as a config section that begins with bar/ and is followed by the name of the bar.

Configuring the tray through the bar section is deprecated in favor of the new tray module.

Note For configuring multiple monitors automatically see https://github.com/polybar/polybar/issues/763

; following horizontal space on the bar:
;   width - border-right-size - border-left-size

Global WM settings

Tells the window manager to add extra space below (with margin-bottom for top bars) or above (with margin-top for bottom bars) the bar window. Whether these settings do anything, heavily depends on your window manager.

Module Settings

A module is defined as a config section that begins with module/ and is followed by the name of the module (this can be different from the module type).

For a module to show up on your bar, you need to place it by adding its name to the modules-left, modules-center, or modules-right settings in the bar section.

; Defines a module named 'mymodule'
[module/mymodule]
; The type of this module
; The wiki pages for the individual modules show the correct values for each module.
type = ...

; Hide the module by default
; Default: false
; New in version 3.6.0
