Raw Blame History

Theme format 3.0

The way rofi handled widgets has changed in the last few releases. Widgets are now put into containers, allowing themes to be much more flexible than before. To expose these new theming abilities a new theming format has been created, replacing the old one. It is loosely based on css, a format widely known, which allows e.g. web developers to create their own rofi themes without learning a new markup.

This file is split up into 3 sections:

Specification of the file format
List of possible options
Examples

File Format Specification

Encoding

The encoding of the file is ascii. Both unix (\n) and windows (\r\n) newlines format are supported. But unix is preferred.

Comments

C and C++ file comments are support.

Anything after // and before a newline is considered a comment.
Everything between /* and */ is a comment.

Comments can be nested and the C++ comments can be inline.

The following is valid:

// Magic comment.
property: /* comment */ value;

However this is not:

prop/*comment*/erty: value;

White space

White space and newlines, like comments, are ignored by the parser.

This:

property: name;

Is identical to:

     property             :
name

;

File extension

The preferred file extension for the new theme format is rasi. This is an abbreviation for rofi aadvanced style information.

Basic Structure

Each element has a section with defined properties. Properties can be inherited to sub-sections. Global properties can be defined in section * { }. Sub-section names begin with a hash symbol #.

It is advised to define the global properties section on top of the file to make inheritance of properties clearer.

/* Global properties section */
* {
    // list of properties
}

/* Element theme section. */
#{element path} {
    // list of properties
}
#{elements... } {
    // list of properties
}

Global properties section

A theme can have one or more global properties sections (If there is more than one they will be merged)

The global properties section denotes the defaults for each element. Each property of this section can be referenced with @{identifier} (See Properties section)

Element theme section

A theme can have multiple element theme sections.

The element path can consist of multiple names separated by whitespace or dots. Each element may contain any number of letters, numbers and '-'. The first element should always start with a #.

This is a valid element name:

#window mainbox listview element normal.normal {
}

And is identical to:

#window.mainbox.listview.element normal.normal {
}

Each section inherits the properties of its parents. Inherited properties can be overridden by defining them again in the section itself. So #window mainbox will contain all properties of #window and #window mainbox.

In the following example:

#window {
 a: 1;
 b: 2;
}
#window mainbox {
    b: 4;
    c: 8;
}

The element #window mainbox will have the following set of properties:

a: 1;
b: 4;
c: 8;

If multiple sections are defined with the same name, they are merged by the parser. If multiple properties with the same name are defined in one section, the last encountered property is used.

Properties

The properties in a section consist of:

{identifier}: {value};

Both fields are manditory for a property.

The identifier names the specified property. Identifiers can consist of any combination of numbers, letters and '-'. It must not contain any whitespace. The structure of the value defines the type of the property.

The current theme format support different type:

a string.
an integer number.
a fractional number.
a boolean value.
a color.
text style.
line style.
a distance.
a padding.
a border.
a position.
a reference.

Some of these types are a combination of other types.

String

Format: "[:print:]+"

A string is always surrounded by quotes ('"'), between the quotes it can have any printable character.

For example:

font: "Awasome 12";

Integer

Format: [-+]?[:digit:]+

An integer may contain any number.

For examples:

lines: 12;

Real

Format: [-+]?[:digit:]+(\.[:digit:]+)?

A real is an integer with an optional fraction.

For example:

real: 3.4;

The following is not valid: .3, 3. or scientific notation: 3.4e-3.

Boolean

Format: (true|false)

Boolean value is either true or false. This is case-sensitive.

For example:

dynamic: false;

Color

Format: #{HEX}{6}
Format: #{HEX}{8}
Format: rgb({INTEGER},{INTEGER},{INTEGER})
Format: rgba({INTEGER},{INTEGER},{INTEGER}, {REAL})

Where '{HEX}' is a hexidecimal number ('0-9a-f'). The '{INTEGER}' value can be between 0 and 255, the '{Real}' value between 0.0 and 1.0.

The first formats specify the color as RRGGBB (R = red, G = green, B = Blue), the second adds an alpha (A) channel: AARRGGB.

For example:

background: #FF0000;
foreground: rgba(0,0,1, 0.5);

Text style

Format: (bold|italic|underline|none)

Text style indicates how the text should be displayed. None indicates no style should be applied.

Line style

Format: (dash|solid)

Indicates how a line should be drawn. It currently supports:

dash: A dashed line. Where the gap is the same width as the dash.
solid: A solid line.

Distance

Format: {Integer}px
Format: {Real}em
Format: {Real}%

A distance can be specified in 3 different units:

px: Screen pixels.
em: Relative to text width.
%: Percentage of the monitor size. Distances used in the horizontal direction use the monitor width. Distances in the vertical direction use the monitor height. For example:

   padding: 10%;

On a full-hd (1920x1080) monitor defines a padding of 192 pixels on the left and right side and 108 pixels on the top and bottom.

Padding

Format: {Integer}
Format: {Distance}
Format: {Distance} {Distance}
Format: {Distance} {Distance} {Distance}
Format: {Distance} {Distance} {Distance} {Distance}

If no unit is set, pixels are used.

The different number of fields in the formats are parsed like:

1 field: all
2 fields: top&bottom left&right
3 fields: top, left&right, bottom
4 fields: top, right, bottom, left

Border

Format: {Integer}
Format: {Distance}
Format: {Distance} {Distance}
Format: {Distance} {Distance} {Distance}
Format: {Distance} {Distance} {Distance} {Distance}
Format: {Distance} {Line style}
Format: {Distance} {Line style} {Distance} {Line style}
Format: {Distance} {Line style} {Distance} {Line style} {Distance} {Line style}
Format: {Distance} {Line style} {Distance} {Line style} {Distance} {Line style} {Distance} {Line style}

Border are identical to padding, except that each distance field has a line style property.

Position

Format: (center|east|north|west|northeast|northweast|south|southwest|southeast)

Reference

Format: @{PROPERTY NAME}

A reference can point to another reference. Currently the maximum number of redirects is 20.

Elements Paths

Element paths exists of two parts, the first part refers to the actual widget by name. Some widgets have an extra state.

For example:

#window mainbox listview element .selected {
}

Here #window mainbox listview element is the name of the widget, selected is the state of the widget.

The difference between dots and spaces is purely cosmetic. These are all the same:

#window mainbox listview element .selected {
}
#window.mainbox.listview.element.selected {
}
#window mainbox listview element selected {
}

Name

The current widgets exist in rofi:

#window
- #window.box: The container holding the window.
- #window.overlay: The overlay widget.
- #window.mainbox
  - #window.mainbox.box: The main vertical @box
  - #window.mainbox.inputbar
    - #window.mainbox.inputbar.box: The horizontal @box packing the widgets.
    - #window.mainbox.inputbar.case-indicator: The case/sort indicator @textbox
    - #window.mainbox.inputbar.prompt: The prompt @textbox
    - #window.mainbox.inputbar.entry: The main entry @textbox
  - #window.mainbox.listview
    - #window.mainbox.listview.box: The listview container.
    - #window.mainbox.listview.scrollbar: The listview scrollbar
    - #window.mainbox.listview.element: The entries in the listview
  - #window.mainbox.sidebar
    - #window.mainbox.sidebar.box: The main horizontal @box packing the buttons.
    - #window.mainbox.sidebar.button: The buttons @textbox for each mode.
  - #window.mainbox.message
    - #window.mainbox.message.textbox: The message textbox.
    - #window.mainbox.message.box: The box containing the message.

Or in a graphical depiction:

State

State: State of widget

Optional flag(s) indicating state.

These are appended after the name or class of the widget.

#window.mainbox.sidebar.button selected.normal { }

#window.mainbox.listview.element selected.urgent { }

Currently only the entrybox and scrollbar have states:

{visible modifier}.{state}

Where visible modifier can be:

normal: No modification.
selected: The entry is selected/highlighted by user.
alternate: The entry is at an alternating row. (uneven row)

Where state is:

normal: No modification.
urgent: This entry is marked urgent.
activE: This entry is marked active.

These can be mixed.

Example:

#name.to.textbox selected.active {
    background: #003642;
    foreground: #008ed4;
}

Sets all selected textboxes marked active to the given foreground and background color.

The scrollbar uses the handle state when drawing the small scrollbar handle. Allowing overriding of color.

all widgets:
- padding: padding Padding on the inside of the widget.
- margin: padding Margin on the outside of the widget.
- border: border Border around the widget (between padding and margin)/
