NAME

       rofi-theme - Rofi theme format files

DESCRIPTION

       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.

FORMAT SPECIFICATION

Encoding

       The  encoding  of the file is utf-8. Both unix (\n) and windows (\r\n) newlines format are supported. But
       unix is preferred.

Comments

       C and C++ file comments are supported.

       •   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  advanced
       style information.

BASIC STRUCTURE

       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.

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

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

       If  there are mulitple sections with the same name, they are merged. Duplicate properties are overwritten
       and the last parsed entry kept.

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)

       A global properties section is indicated with a * as element path.

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 -´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:

           element normal.normal {
               background-color: blue;
           }
           button {
               background-color: blue;
           }

       And is identical to:

           element normal normal, button {
               background-color: blue;
           }

       Each  section  inherits  the global properties. Properties can be explicitely inherited from there parent
       with the inherit keyword. In the following example:

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

       The element mainbox will have the following set of properties (if mainbox is a child of window):

           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 FORMAT

       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 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:

       •   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

       •   an orientation

       •   a list of keywords

       •   Inherit

       Some of these types are a combination of other types.

String

       •   Format: "[:print:]+"

       A string is always surrounded by double quotes (").  Between  the  quotes  there  can  be  any  printable
       character.

       For example:

           font: "Awasome 12";

       The string must be valid UTF-8.

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

       rofi supports the color formats as specified in the CSS standard (1,2,3 and some of CSS 4)

       •   Format: #{HEX}{3} (rgb)

       •   Format: #{HEX}{4} (rgba)

       •   Format: #{HEX}{6} (rrggbb)

       •   Format: #{HEX}{8} (rrggbbaa)

       •   Format: rgb[a]({INTEGER},{INTEGER},{INTEGER}[, {PERCENTAGE}])

       •   Format: rgb[a]({INTEGER}%,{INTEGER}%,{INTEGER}%[, {PERCENTAGE}])

       •   Format: hsl[a]( {ANGLE}, {PERCENTAGE}, {PERCENTAGE} [, {PERCENTAGE}])

       •   Format: hwb[a]( {ANGLE}, {PERCENTAGE}, {PERCENTAGE} [, {PERCENTAGE}])

       •   Format: cmyk( {PERCENTAGE}, {PERCENTAGE}, {PERCENTAGE}, {PERCENTAGE} [, {PERCENTAGE} ])

       •   Format: {named-color} [ / {PERCENTAGE} ]

       The white-space format proposed in CSS4 is also supported.

       The different values are:

       •   {HEX} is a hexidecimal number (´0-9a-f´ case insensitive).

       •   {INTEGER} value can be between 0 and 255 or 0-100 when representing percentage.

       •   {ANGLE} is the angle on the color wheel, can be in deg, rad, grad or turn. When no unit is specified,
           degrees is assumed.

       •   {PERCENTAGE} can be between 0-1.0, or 0%-100%

       •   {named-color} is one of the following colors:

           AliceBlue, AntiqueWhite,  Aqua,  Aquamarine,  Azure,  Beige,  Bisque,  Black,  BlanchedAlmond,  Blue,

       For example:

           background-color: #FF0000;
           border-color: rgba(0,0,1, 0.5);
           text-color: SeaGreen;

       or

           background-color: transparent;
           text-color: Black;

Text style

       •   Format: (bold|italic|underline|strikethrough|none)

       Text  style  indicates  how the highlighted text is emphasized. None indicates that no emphasis should be
       applied.

       •   bold: make the text thicker then the surrounding text.

       •   italic: put the highlighted text in script type (slanted).

       •   underline: put a line under the highlighted text.

       •   strikethrough: put a line through the highlighted text.

       •   small caps: emphasise the text using capitalization.

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}ch

       •   Format: {Real}%

       A distance can be specified in 3 different units:

       •   px: Screen pixels.

       •   em: Relative to text height.

       •   ch: Relative to width of a single number.

       •   %: 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, it 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 specified, 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}

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

Position

       Indicate a place on the window/monitor.

       •   Format: (center|east|north|west|south|north east|north west|south west|south east)

           north west   |    north    |  north east
           -------------|-------------|------------
                 west   |   center    |  east
           -------------|-------------|------------
           south west   |    south    |  south east

Visibility

       It is possible to hide widgets:

       inputbar { enabled: false; }

Reference

       •   Format: @{PROPERTY NAME}

       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:

           highlight: bold @pink;

       But this is:

           * {
               myhigh: bold #FAA;
           }

           window {
               highlight: @myhigh;
           }

Orientation

       •   Format: (horizontal|vertical)

       Specify the orientation of the widget.

List of keywords

       •   Format: [ keyword, keyword ]

       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.

Inherit

       •   Format: inherit

       Inherits the property from its parent widget.

           mainbox {
               border-color: inherit;
           }

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:

           element selected {
           }

       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:

           element .selected {

           element.selected {
           }
           element selected {
           }

SUPPORTED ELEMENT PATH

Name

       The current widgets available in rofi:

       •

       •   overlay: the overlay widget.

       •

       •

       •   box: the horizontal @box packing the widgets

       •   case-indicator: the case/sort indicator @textbox

       •   prompt: the prompt @textbox

       •   entry: the main entry @textbox

       •

       •   scrollbar: the listview scrollbar

       •   element: the entries in the listview

       •

       •   button: the buttons @textbox for each mode

       •

       •   textbox: the message textbox

       Note that these path names match the default theme.  Themes  that  provide  a  custom  layout  will  have
       different element paths.

State

       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.

   Example:
       button selected.normal { }

       element selected.urgent { }

       Currently only the entrybox and scrollbar have states:

   Entrybox:
       {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:

           nametotextbox selected.active {
               background-color: #003642;
               text-color: #008ed4;
           }

       Sets all selected textboxes marked active to the given foreground and background color. Note that a state
       modifies the original element, it therefor contains all the properties of that element.

   Scrollbar
       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.

Layout

       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.

   Basic 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:

           |------------------------------------------------------------------------------------|
           | window {BOX:vertical}                                                              |
           | |-------------------------------------------------------------------------------|  |
           | | mainbox  {BOX:vertical}                                                       |  |
           | | |---------------------------------------------------------------------------| |  |
           | | | inputbar {BOX:horizontal}                                                 | |  |
           | | | |---------| |-----------------------------------------------------| |---| | |  |
           | | | | prompt  | | entry                                               | |ci | | |  |

   Advanced layout
       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:

       •   prompt

       •   entry

       •   case-indicator

       •   message

       •   listview

       •   sidebar

       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.

       •   mainbox Packs: inputbar, message, listview, sidebar

       •   inputbar Packs: prompt,entry,case-indicator

       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):

           children: [prompt,entry,case-indicator];

       The theme needs to be updated to match the hierarchy specified.

       Below is an example of a theme emulating dmenu:

           * {
               background-color:      Black;
               text-color:            White;
               border-color:          White;
               font:            "Times New Roman 12";
           }

           window {
               anchor:     north;
               location:   north;
               width:      100%;
               padding:    4px;
               children:   [ horibox ];
           }

           horibox {
               orientation: horizontal;
               children:   [ prompt, entry, listview ];
           }

           listview {
               layout:     horizontal;
               spacing:    5px;
               lines:      10;
           }

           entry {
               expand:     false;
               width:      10em;
           }

           element {
               padding: 0px 2px;
           }
           element selected {
               background-color: SteelBlue;
           }

   Padding and margin
       Just like CSS, rofi uses the box model for each widget.

           |-------------------------------------------------------------------|
           | margin                                                            |
           |  |-------------------------------------------------------------|  |
           |  | border                                                      |  |
           |  | |---------------------------------------------------------| |  |
           |  | | padding                                                 | |  |
           |  | | |-----------------------------------------------------| | |  |
           |  | | | content                                             | | |  |
           |  | | |-----------------------------------------------------| | |  |
           |  | |---------------------------------------------------------| |  |
           |  |-------------------------------------------------------------|  |
           |-------------------------------------------------------------------|

       Explanation of the different parts:

       •   Content - The content of the widget.

       •   Padding - Clears an area around the widget. The padding shows the background color of the widget.

       •   Border  -  A  border that goes around the padding and content. The border use the foreground color of
           the widget.

       •   Margin - Clears an area outside the border. The margin is transparent.

       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.

   Spacing
       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).

           |---------------------------------------|
           |  |--------| s |--------| s |-------|  |
           |  | child  | p | child  | p | child |  |
           |  |        | a |        | a |       |  |
           |  |        | c |        | c |       |  |
           |  |        | i |        | i |       |  |
           |  |        | n |        | n |       |  |
           |  |--------| g |--------| g |-------|  |
           |---------------------------------------|

   Advanced box packing
       More dynamic spacing can be achieved by adding dummy widgets, for example to make one widget centered:

           |--------------------------------------------|
           |  |-----------|  |--------|  |-----------|  |
           |  | dummy     |  | child  |  | dummy     |  |
           |  | expand: y |  |        |  | expand: y |  |
           |  |           |  |        |  |           |  |
           |  |           |  |        |  |           |  |
           |  |           |  |        |  |           |  |
           |  |-----------|  |--------|  |-----------|  |
           |--------------------------------------------|

       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).

DEBUGGING

       To get debug information from the parser, run rofi like:

           G_MESSAGES_DEBUG=Parser rofi -show run

       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:

           G_MESSAGES_DEBUG=Theme rofi -show run

       To test minor changes, part of the theme can be passed on the command line, for  example  to  set  it  to
       full-screen:

           rofi -theme-str ´#window { fullscreen:true;}´ -show run

       To print the current theme, run:

           rofi -dump-theme

EXAMPLES

       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/.
