\fBrofi-theme\fP - Rofi theme format files

.SH Getting started with theming
.PP
The easiest way to get started theming rofi is by modifying your existing theme.

.PP
Themes can be modified/tweaked by adding theming elements to the end of the
.br
config file. The default location of this file is \fB\fC~/.config/rofi/config.rasi\fR,
if the file does not exists, you can create it.

.PP
A basic config:

.PP
.RS

.nf
configuration {
  modes: [ combi ];
  combi-modes: [ window, drun, run ];
}

@theme "gruvbox-light"
 
/* Insert theme modifications after this */

.fi
.RE

.PP
For example if we want to change the \fB\fCType to filter\fR text in the entry box we
append the following:

.PP
.RS

.nf
entry {
    placeholder: "Type here";
}

.fi
.RE

.PP
In the above section, \fB\fCentry\fR indicates the widget, \fB\fCplaceholder\fR is the
property we want to modify and we set it to the string \fB\fC"Type here"\fR\&.
To find the commonly available widgets in rofi, see the 'Basic structure' section.

.PP
To change the mouse over cursor to a pointer, add:

.PP
.RS

.nf
entry {
    placeholder: "Type here";
    cursor: pointer;
}

.fi
.RE

.PP
For the next modification, we want to add the icon after each text element and
increase the size. First we start by modifying the \fB\fCelement\fR widget:

.PP
.RS

.nf

element {
  orientation: horizontal;
  children: [ element-text, element-icon ];
  spacing: 5px;
}


.fi
.RE

.PP
Resulting in the following packing:

.PP
.RS

.nf
┌─────────────────────────────────────────────────────────────────────┐ 
│ element                                                             │

└─────────────────────────────────────────────────────────────────────┘ 

.fi
.RE

.PP
The \fB\fCelement\fR (container) widget hold each entry in the \fB\fClistview\fR, we add the
two pre-defined children in the order we want to show. We also specify the
packing direction (\fB\fCorientation\fR) and the spacing between the children
(\fB\fCspacing\fR). We specify the space between the two children in absolute pixels
(\fB\fCpx\fR).

.PP
To increase the icon-size, we need to modify the \fB\fCelement-icon\fR widget.

.PP
.RS

.nf
element-icon {
    size: 2.5em;
}

.fi
.RE

.PP
.RS

.nf

.fi
.RE

.PP
In this example we specify the size in the em
\[la]https://www.w3.org/Style/LieBos3e/em\[ra] unit.

.PP
Now lets change the text color of both the \fB\fCentry\fR and the \fB\fCelement-text\fR widget to red and background to blue.

.PP
.RS

.nf
entry, element-text {
  text-color: red;
  background-color: rgb(0,0,255);
}

.fi
.RE

.PP
Here we use two different methods of writing down the color, for \fB\fCtext-color\fR
we used a named color, for \fB\fCbackground-color\fR we specify it in \fB\fCrgb\fR\&.
We also specify the property for multiple widgets by passing a comma separated
list of widget names.

.PP
If you want to center the text relative to the icon, we can set this:

.PP
.RS

.nf
element-text {
    vertical-align: 0.5;
}

.fi
.RE

.PP
.RS

.nf
┌─────────────────────────────────────────────────────────────────────┐

│ └─────────────────────────────────────────────┘ └─────────────────┘ │ 
└─────────────────────────────────────────────────────────────────────┘ 

.fi
.RE

.PP
We can also specify the color and width of the cursor. You could, for example,
create a crimson block cursor like this:

.PP
.RS

.nf
entry {
  cursor-color: rgb(220,20,60);
  cursor-width: 8px;
}

.fi
.RE

.PP
By default, the \fB\fCcursor-color\fR will be the same as the \fB\fCtext-color\fR\&. The \fB\fCcursor-width\fR will always default to 2 pixels.

.PP
If you want to see the complete theme, including the modification you can run:

.PP
.RS

.nf
rofi -dump-theme

.fi
.RE

.SH Default theme loading
.PP
By default, rofi loads the default theme. This theme is \fBalways\fP loaded.
The default configuration contains:

.PP
.RS

.nf
@theme "default"

.fi
.RE

.PP
To unload the default theme, and load another theme, add the \fB\fC@theme\fR statement
to your \fB\fCconfig.rasi\fR file.

.PP
If you have a theme loaded via \fB\fC@theme\fR or use the default theme, you can tweak
it by adding overriding elements at the end of your \fB\fCconfig.rasi\fR file.

.PP
For the difference between \fB\fC@import\fR and \fB\fC@theme\fR see the \fB\fCMultiple file
handling\fR section in this manpage.

.PP
To see the default theme, run the following command:

.PP
.RS

.nf
rofi -no-config -dump-theme

.fi
.RE

.SH Description
.PP
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. Therefore, a new file format has been created, replacing the old one.

.SH Format specification
.SH Encoding
.PP
The encoding of the file is UTF-8. Both unix (\fB\fC\\n\fR) and windows (\fB\fC\\r\\n\fR) newlines format are supported. But unix is
preferred.

.SH Comments
.PP
C and C++ file comments are supported.

.RS
.IP \(bu 2
Anything after  \fB\fC//\fR and before a newline is considered a comment.
.IP \(bu 2
Everything between \fB\fC/*\fR and \fB\fC*/\fR is a comment, this comment can span multiple lines.

.RE

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

.PP
The following is valid:

.PP
.RS

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

.fi
.RE

.PP
However, this is not:

.PP
.RS

.nf
prop/*comment*/erty: value;

.fi
.RE

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

.PP
This:

.PP
.RS

.nf
property: name;

.fi
.RE

.PP
Is identical to:

.PP
.RS

.nf
     property             :
name

;

.fi
.RE

.SH File extension
.PP
The preferred file extension for the new theme format is \fBrasi\fP\&. This is an
abbreviation for \fBr\fPofi \fBa\fPdvanced \fBs\fPtyle \fBi\fPnformation.
If a theme file is split over multiple files, include files can have the: \fBrasinc\fP extension.

.SH Basic Structure
.PP
Each element has a section with defined properties. Global properties can be defined in section \fB\fC* { }\fR\&.
Sub-section names begin with an optional hash symbol \fB\fC#\fR\&.

.PP
It is advised to define the \fIglobal properties section\fP on top of the file to
make inheritance of properties clearer.

.PP
.RS

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

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

.fi
.RE

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

.SH Global properties section
.PP
A theme can have one or more global properties sections. If there is more than one,
they will be merged.

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

.PP
A global properties section is indicated with a \fB\fC*\fR as element path.

.SH Element theme section
.PP
A theme can have multiple element theme sections.

.PP
The element path can consist of multiple names separated by whitespace or dots.
Each element may contain any number of letters, numbers and \fB\fC-\fR\&'s.
The first element in the element path can optionally start with a \fB\fC#\fR (for
historic reasons). Multiple elements can be specified by a \fB\fC,\fR\&.

.PP
This is a valid element name:

.PP
.RS

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

.fi
.RE

.PP
And is identical to:

.PP
.RS

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

.fi
.RE

.PP
Each section inherits the global properties. Properties can be explicitly
inherited from their parent with the \fB\fCinherit\fR keyword.
In the following example:

.PP
.RS

.nf
window {
 a: 1;
 b: 2;
 children: [ mainbox ];
}
mainbox {
    a: inherit;
    b: 4;
    c: 8;
}

.fi
.RE

.PP
The element \fB\fCmainbox\fR will have the following set of properties (if \fB\fCmainbox\fR
is a child of \fB\fCwindow\fR):

.PP
.RS

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

.fi
.RE

.PP
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.

.SH Properties Format
.PP
The properties in a section consist of:

.PP
.RS

.nf
{identifier}: {value};

.fi
.RE

.PP
Both fields are mandatory for a property.

.PP
The \fB\fCidentifier\fR names the specified property. Identifiers can consist of any
combination of numbers, letters and '-'. It must not contain any whitespace.
The structure of the \fB\fCvalue\fR defines the type of the property. The current
parser does not define or enforce a certain type of a particular \fB\fCidentifier\fR\&.
When used, values with the wrong type that cannot be converted are ignored.

.PP
The current theme format supports different types:

.RS

Note that these path names match the default theme. Themes that provide a custom layout will have different
elements, and structure.

.SS State
.PP
State: State of widget

.PP
Optional flag(s) indicating state of the widget, used for theming.

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

.SS Example:
.PP
\fB\fCbutton selected.normal { }\fR

.PP
\fB\fCelement selected.urgent { }\fR

.PP
Currently only the entrybox and scrollbar have states:

.SS Entrybox:

\fB\fC{visible modifier}.{state}\fR

.PP
Where \fB\fCvisible modifier\fR can be:
 * normal: no modification

If the property \fB\fCaction\fR is set, it acts as a button.
\fB\fCaction\fR can be set to a keybinding name and completes that action. (see rofi -show keys for a list).

.PP
If the \fB\fCsquared\fR property is set to \fBfalse\fP the widget height and width are not forced to be equal.

.PP
Example:

.PP
.RS

.nf
icon-paste {
    expand: false;
    filename: "gtk-paste";
    size: 24;
    vertical-align: 0.5;

.SS button
.PP
This is a textbox widget that can have a 'clickable' action.

Explanation of the different parts:

.RS
.IP \(bu 2
Content - The content of the widget.
.IP \(bu 2
Padding - Clears an area around the widget.
The padding shows the background color of the widget.
.IP \(bu 2
Border - A border that goes around the padding and content.
The border use the border-color of the widget.
.IP \(bu 2
Margin - Clears an area outside the border.
The margin is transparent.

.RE

.PP
The box model allows us to add a border around elements, and to define space between elements.

.PP
The size of each margin, border, and padding can be set.
For the border, a linestyle and radius can be set.

.SS Spacing
.PP
Widgets that can pack more then one child widget (currently box and listview) have the \fB\fCspacing\fR property.
This property sets the distance between the packed widgets (both horizontally and vertically).

.PP
.RS

.RE

.PP
If both dummy widgets are set to expand, \fB\fCchild\fR will be centered. Depending on the \fB\fCexpand\fR flag of child the
remaining space will be equally divided between both dummy and child widget (expand enabled), or both dummy widgets
(expand disabled).

.SH Debugging
.PP
To get debug information from the parser, run rofi like:

.PP
.RS

.nf
G_MESSAGES_DEBUG=Parser rofi -show run

.fi
.RE

.PP
Syntax errors are shown in a popup and printed out to command line with the above command.

.PP
To see the elements queried during running, run:

.PP
.RS

.nf

.fi
.RE

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

.PP
.RS

.nf

.fi
.RE

.PP
Another syntax to modify theme properties is:

.PP

\fB\fCmonitor-id\fR:        The monitor id, see rofi -help for id's.
.IP \(bu 2
\fB\fCenabled\fR:           Boolean option to enable. Supports environment variable.

.SH Conflicting constraints
.PP
It is possible to define conflicting constraints in the theme. These conflicts
are not explicitly reported. The most common example is forcing a specific
window size, for example by enabling full-screen mode, having number of lines
set in the listview and having the listview expand to available space. There is
clearly a conflict in these 3 constraints. In this case, listview will not
limit to the number of lines, but tries to fill the available space. It is up
to the theme designer to make sure the theme handles this correctly.

.SH Font Parsing
.PP
Rofi uses pango
\[la]https://pango.gnome.org/\[ra] for font rendering. The font should
be specified in a format that pango understands. This normally is the font name
followed by the font size. For example:

.PP
.RS

.nf
mono 18

.fi
.RE

.PP
Or

.PP
.RS

.nf
FontAwesome 22

.fi
.RE

.PP
From the pango manpage:

.PP
The string must have the form

.PP
\fB\fC\\[FAMILY-LIST] \\[STYLE-OPTIONS] \\[SIZE] \\[VARIATIONS]\fR,

.PP
where FAMILY-LIST is a comma-separated list of families optionally terminated
by a comma, STYLE_OPTIONS is a whitespace-separated list of words where each
word describes one of style, variant, weight, stretch, or gravity, and SIZE is
a decimal number (size in points) or optionally followed by the unit modifier
“px” for absolute size. VARIATIONS is a comma-separated list of font variation
specifications of the form “\fB\fCaxis\fR=value” (the = sign is optional).

.PP
The following words are understood as styles: "Normal”, “Roman”, “Oblique”,
“Italic”.

.PP
The following words are understood as variants: “Small-Caps”, “All-Small-Caps”,
“Petite-Caps”, “All-Petite-Caps”, “Unicase”, “Title-Caps”.

.PP
The following words are understood as weights: “Thin”, “Ultra-Light”,
“Extra-Light”, “Light”, “Semi-Light”, “Demi-Light”, “Book”, “Regular”,
“Medium”, “Semi-Bold”, “Demi-Bold”, “Bold”, “Ultra-Bold”, “Extra-Bold”,
“Heavy”, “Black”, “Ultra-Black”, “Extra-Black”.

.PP
The following words are understood as stretch values: “Ultra-Condensed”,
“Extra-Condensed”, “Condensed”, “Semi-Condensed”, “Semi-Expanded”, “Expanded”,
“Extra-Expanded”, “Ultra-Expanded”.

.PP
The following words are understood as gravity values: “Not-Rotated”, “South”,
“Upside-Down”, “North”, “Rotated-Left”, “East”, “Rotated-Right”, “West”.

.PP
Any one of the options may be absent. If FAMILY-LIST is absent, then the
family_name field of the resulting font description will be initialized to
NULL. If STYLE-OPTIONS is missing, then all style options will be set to the
default values. If SIZE is missing, the size in the resulting font description
will be set to 0.

.PP
A typical example:

.PP
"Cantarell Italic Light 15 `wght`=200"

.SH Icon Handling
.PP
Rofi supports 3 ways of specifying an icon:

.RS
.IP \(bu 2
Filename
.IP \(bu 2
icon-name, this is looked up via the icon-theme.
.IP \(bu 2
Markup String. It renders a string as an icon.

.RE

.PP
For the first two options, GdkPixbuf is used to open and render the icons.
This in general gives support for most required image formats.
For the string option it uses Pango to render the string. The string needs to
start with a \fB\fC<span\fR tag, that allows you to set color and font.

.PP
Markup string:

.PP
.RS

.nf
echo -en "testing\\0icon\\x1f<span color='red'>⏻</span>" | ./rofi -dmenu

.fi
.RE

.PP
Getting supported icon formats:

.PP
.RS

.nf

.fi
.RE

.PP
This uses the debug framework and prints out a list of supported image  file
extensions.

.SH Multiple file handling
.PP
The rasi file format offers two methods of including other files.
This can be used to modify existing themes, or have multiple variations on a theme.

.RS
.IP \(bu 2
import:  Import and parse a second file.
.IP \(bu 2
theme:   Discard theme, and load file as a fresh theme.

.RE

.PP
Syntax:

.PP
.RS

.nf
@import "myfile"
@theme "mytheme"

.fi
.RE

.PP
The specified file can either by \fIname\fP, \fIfilename\fP,\fIfull path\fP\&.

.PP
If a filename is provided, it will try to resolve it in the following order:

.RS
.IP \(bu 2
\fB\fC${XDG_CONFIG_HOME}/rofi/themes/\fR
.IP \(bu 2
\fB\fC${XDG_CONFIG_HOME}/rofi/\fR
.IP \(bu 2
\fB\fC${XDG_DATA_HOME}/rofi/themes/\fR
.IP \(bu 2
\fB\fC${INSTALL PREFIX}/share/rofi/themes/\fR

.RE

.PP
A name is resolved as a filename by appending the \fB\fC\&.rasi\fR extension.

.SH Examples
.PP
Several examples are installed together with \fBrofi\fP\&. These can be found in \fB\fC{datadir}/rofi/themes/\fR, where
\fB\fC{datadir}\fR is the install path of \fBrofi\fP data. When installed using a package manager, this is usually: \fB\fC/usr/share/\fR\&.
