rofi-theme — Rofi theme format files The need for a new theme format was motivated by the fact that the way rofi handled widgets has changed. From a very static drawing of lines and text to a nice structured form of packing widgets. This change made it possible to provide a more flexible theme framework. The old theme format and config file are not flexible enough to expose these options in a user-friendly way. Therefor, a new file format has been created, replacing the old one. The encoding of the file is utf-8. Both unix (\n) and windows (\r\n) newlines format are supported. But unix is preferred. C and C++ file comments are supported. Comments can be nested and the C comments can be inline. The following is valid: However, this is not: White space and newlines, like comments, are ignored by the parser. This: Is identical to: The preferred file extension for the new theme format is rasi. This is an abbreviation for rofi advanced style information. Each element has a section with defined properties. 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. If there are multiple sections with the same name, they are merged. Duplicate properties are overwritten and the last parsed entry kept. 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) A global properties section is indicated with a * as element path. 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 -´s. The first element in the element path should always start with a #. Multiple elements can be specified by a ,. This is a valid element name: And is identical to: Each section inherits the global properties. Properties can be explicitly inherited from their parent with the inherit keyword. In the following example: The element mainbox will have the following set of properties (if mainbox is a child of window): 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. The properties in a section consist of: Both fields are mandatory 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 parser does not define or enforce a certain type of a particular identifier. When used, values with the wrong type that cannot be converted are ignored. The current theme format supports different types: Some of these types are a combination of other types. A string is always surrounded by double quotes ("). Between the quotes there can be any printable character. For example: The string must be valid UTF-8. An integer may contain any number. For examples: A real is an integer with an optional fraction. For example: The following is not valid: .3, 3. or scientific notation: 3.4e-3. Boolean value is either true or false. This is case-sensitive. For example: rofi supports the color formats as specified in the CSS standard (1,2,3 and some of CSS 4) The white-space format proposed in CSS4 is also supported. The different values are: {named-color} is one of the following colors: AliceBlue, AntiqueWhite, Aqua, Aquamarine, Azure, Beige, Bisque, Black, BlanchedAlmond, Blue, BlueViolet, Brown, BurlyWood, CadetBlue, Chartreuse, Chocolate, Coral, CornflowerBlue, Cornsilk, Crimson, Cyan, DarkBlue, DarkCyan, DarkGoldenRod, DarkGray, DarkGrey, DarkGreen, DarkKhaki, DarkMagenta, DarkOliveGreen, DarkOrange, DarkOrchid, DarkRed, DarkSalmon, DarkSeaGreen, DarkSlateBlue, DarkSlateGray, DarkSlateGrey, DarkTurquoise, DarkViolet, DeepPink, DeepSkyBlue, DimGray, DimGrey, DodgerBlue, FireBrick, FloralWhite, ForestGreen, Fuchsia, Gainsboro, GhostWhite, Gold, GoldenRod, Gray, Grey, Green, GreenYellow, HoneyDew, HotPink, IndianRed, Indigo, Ivory, Khaki, Lavender, LavenderBlush, LawnGreen, LemonChiffon, LightBlue, LightCoral, LightCyan, LightGoldenRodYellow, LightGray, LightGrey, LightGreen, LightPink, LightSalmon, LightSeaGreen, LightSkyBlue, LightSlateGray, LightSlateGrey, LightSteelBlue, LightYellow, Lime, LimeGreen, Linen, Magenta, Maroon, MediumAquaMarine, MediumBlue, MediumOrchid, MediumPurple, MediumSeaGreen, MediumSlateBlue, MediumSpringGreen, MediumTurquoise, MediumVioletRed, MidnightBlue, MintCream, MistyRose, Moccasin, NavajoWhite, Navy, OldLace, Olive, OliveDrab, Orange, OrangeRed, Orchid, PaleGoldenRod, PaleGreen, PaleTurquoise, PaleVioletRed, PapayaWhip, PeachPuff, Peru, Pink, Plum, PowderBlue, Purple, RebeccaPurple, Red, RosyBrown, RoyalBlue, SaddleBrown, Salmon, SandyBrown, SeaGreen, SeaShell, Sienna, Silver, SkyBlue, SlateBlue, SlateGray, SlateGrey, Snow, SpringGreen, SteelBlue, Tan, Teal, Thistle, Tomato, Turquoise, Violet, Wheat, White, WhiteSmoke, Yellow, YellowGreen,transparent For example: or Text style indicates how the highlighted text is emphasized. None indicates that no emphasis should be applied. 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 A distance can be specified in 3 different units: Distances used in the horizontal direction use the monitor width. Distances in the vertical direction use the monitor height. For example: On a full-HD (1920x1080) monitor, it defines a padding of 192 pixels on the left and right side and 108 pixels on the top and bottom. If no unit is specified, pixels are used. The different number of fields in the formats are parsed like: Borders are identical to padding, except that each distance field has a line style property. Indicate a place on the window/monitor. Format: (center|east|north|west|south|north east|north west|south west|south east) It is possible to hide widgets: inputbar { enabled: false; } A reference can point to another reference. Currently, the maximum number of redirects is 20. A property always refers to another property. It cannot be used for a subpart of the property. For example, this is not valid: But this is: Specify the orientation of the widget. A list starts with a ´[´ and ends with a ´]´. The entries in the list are comma-separated. The keyword in the list refers to an widget name. This will parse the environment variable as the property value. (that then can be any of the above types). The environment variable should be an alphanumeric string without white-space. Inherits the property from its parent widget. Element paths exists of two parts, the first part refers to the actual widget by name. Some widgets have an extra state. For example: Here element selected 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: The current widgets available in rofi: Note that these path names match the default theme. Themes that provide a custom layout will have different element paths. State: State of widget Optional flag(s) indicating state of the widget, used for theming. These are appended after the name or class of the widget. button selected.normal { } 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: Sets all selected textboxes marked active to the given text and background color. Note that a state modifies the original element, it therefore contains all the properties of that element. The scrollbar uses the handle state when drawing the small scrollbar handle. This allows the colors used for drawing the handle to be set independently. The following properties are currently supported: The new format allows the layout of the rofi window to be tweaked extensively. For each widget, the themer can specify padding, margin, border, font, and more. It even allows, as an advanced feature, to pack widgets in a custom structure. The whole view is made out of boxes that pack other boxes or widgets. The box can be vertical or horizontal. This is loosely inspired by GTK http://gtk.org/. The current layout of rofi is structured as follows: The layout of rofi can be tweaked by packing the ´fixed´ widgets in a custom structure. The following widgets are fixed, as they provide core rofi functionality: The following keywords are defined and can be used to automatically pack a subset of the widgets. These are used in the default theme as depicted in the figure above. Any widget name starting with textbox is a textbox widget, others are box widgets and can pack other widgets. To specify children, set the children property (this always happens on the box child, see example below): The theme needs to be updated to match the hierarchy specified. Below is an example of a theme emulating dmenu: Just like CSS, rofi uses the box model for each widget. Explanation of the different parts: The box model allows us to add a border around elements, and to define space between elements. The size of each margin, border, and padding can be set. For the border, a linestyle and radius can be set. Widgets that can pack more then one child widget (currently box and listview) have the spacing property. This property sets the distance between the packed widgets (both horizontally and vertically). More dynamic spacing can be achieved by adding dummy widgets, for example to make one widget centered: If both dummy widgets are set to expand, child will be centered. Depending on the expand flag of child the remaining space will be equally divided between both dummy and child widget (expand enabled), or both dummy widgets (expand disabled). To get debug information from the parser, run rofi like: Syntax errors are shown in a popup and printed out to command line with the above command. To see the elements queried during running, run: To test minor changes, part of the theme can be passed on the command line, for example to set it to full-screen: To print the current theme, run: Several examples are installed together with rofi. These can be found in {datadir}/rofi/themes/, where {datadir} is the install path of rofi data. When installed using a package manager, this is usually: /usr/share/.Description
