@node Theme file format
@chapter Theme file format
@section Introduction
The GRUB graphical menu supports themes that can customize the layout and
appearance of the GRUB boot menu. The theme is configured through a plain
text file that specifies the layout of the various GUI components (including
the boot menu, timeout progress bar, and text messages) as well as the
appearance using colors, fonts, and images. Example is available in docs/example_theme.txt
@section Theme Elements
@subsection Colors
Colors can be specified in several ways:
@itemize
@item HTML-style ``#RRGGBB'' or ``#RGB'' format, where *R*, *G*, and *B* are hexadecimal digits (e.g., ``#8899FF'')
@item as comma-separated decimal RGB values (e.g., ``128, 128, 255'')
@item with ``SVG 1.0 color names'' (e.g., ``cornflowerblue'') which must be specified in lowercase.
@end itemize
@subsection Fonts
The fonts GRUB uses ``PFF2 font format'' bitmap fonts. Fonts are specified
with full font names. Currently there is no
provision for a preference list of fonts, or deriving one font from another.
Fonts are loaded with the ``loadfont'' command in GRUB. To see the list of
loaded fonts, execute the ``lsfonts'' command. If there are too many fonts to
fit on screen, do ``set pager=1'' before executing ``lsfonts''.
@subsection Progress Bar
@float Figure, Pixmap-styled progress bar
@c @image{Theme_progress_bar,,,,.png}
@end float
@float Figure, Plain progress bar, drawn with solid color.
@c @image{Theme_progress_bar_filled,,,,.png}
@end float
Progress bars are used to display the remaining time before GRUB boots the
default menu entry. To create a progress bar that will display the remaining
time before automatic boot, simply create a ``progress_bar'' component with
the id ``__timeout__''. This indicates to GRUB that the progress bar should
be updated as time passes, and it should be made invisible if the countdown to
automatic boot is interrupted by the user.
Progress bars may optionally have text displayed on them. This is controlled
through the ``show_text'' property, which can be set to either ``true'' or
``false'' to control whether text is displayed. When GRUB is counting down to
automatic boot, the text informs the user of the number of seconds remaining.
@subsection Circular Progress Indicator
@c @image{Theme_circular_progress,,,,.png}
The circular progress indicator functions similarly to the progress bar. When
given an id of ``__timeout__'', GRUB updates the circular progress indicator's
value to indicate the time remaining. For the circular progress indicator,
there are two images used to render it: the *center* image, and the *tick*
image. The center image is rendered in the center of the component, while the
tick image is used to render each mark along the circumference of the
indicator.
@subsection Labels
Text labels can be placed on the boot screen. The font, color, and horizontal
alignment can be specified for labels. If a label is given the id
``__timeout__'', then the ``text'' property for that label is also updated
with a message informing the user of the number of seconds remaining until
automatic boot. This is useful in case you want the text displayed somewhere
else instead of directly on the progress bar.
@subsection Boot Menu
@c @image{Theme_boot_menu,,,,.png}
The boot menu where GRUB displays the menu entries from the ``grub.cfg'' file.
It is a list of items, where each item has a title and an optional icon. The
icon is selected based on the *classes* specified for the menu entry. If
there is a PNG file named ``myclass.png'' in the ``grub/themes/icons''
directory, it will be displayed for items which have the class *myclass*. The
boot menu can be customized in several ways, such as the font and color used
for the menu entry title, and by specifying styled boxes for the menu itself
and for the selected item highlight.
@subsection Styled Boxes
One of the most important features for customizing the layout is the use of
*styled boxes*. A styled box is composed of 9 rectangular (and potentially
empty) regions, which are used to seamlessly draw the styled box on screen:
@multitable @columnfractions 0.3 0.3 0.3
@item Northwest (nw) @tab North (n) @tab Northeast (ne)
@item West (w) @tab Center (c) @tab East (e)
@item Southwest (sw) @tab South (s) @tab Southeast (se)
@end multitable
To support any size of box on screen, the center slice and the slices for the
top, bottom, and sides are all scaled to the correct size for the component on
screen, using the following rules:
@enumerate
@item The edge slices (north, south, east, and west) are scaled in the direction of the edge they are adjacent to. For instance, the west slice is scaled vertically.
@item The corner slices (northwest, northeast, southeast, and southwest) are not scaled.
@item The center slice is scaled to fill the remaining space in the middle.
@end enumerate
As an example of how an image might be sliced up, consider the styled box
used for a terminal view.
@float Figure, An example of the slices (in red) used for a terminal window. This drawing was created and sliced in Inkscape_, as the next section explains.
@c @image{Box_slice_example_terminal,,,,.png}
@end float
@subsection Creating Styled Box Images
The Inkscape_ scalable vector graphics editor is a very useful tool for
creating styled box images. One process that works well for slicing a drawing
into the necessary image slices is:
@enumerate
@item Create or open the drawing you'd like use.
@item Create a new layer on the top of the layer stack. Make it visible. Select this layer as the current layer.
@item Draw 9 rectangles on your drawing where you'd like the slices to be. Clear the fill option, and set the stroke to 1 pixel wide solid stroke. The corners of the slices must meet precisely; if it is off by a single pixel, it will probably be evident when the styled box is rendered in the GRUB menu. You should probably go to File | Document Properties | Grids and enable a grid or create a guide (click on one of the rulers next to the drawing and drag over the drawing; release the mouse button to place the guide) to help place the rectangles precisely.
@item Right click on the center slice rectangle and choose Object Properties. Change the "Id" to ``slice_c`` and click Set. Repeat this for the remaining 8 rectangles, giving them Id values of ``slice_n``, ``slice_ne``, ``slice_e``, and so on according to the location.
@item Save the drawing.
@item Select all the slice rectangles. With the slice layer selected, you can simply press Ctrl+A to select all rectangles. The status bar should indicate that 9 rectangles are selected.
@item Click the layer hide icon for the slice layer in the layer palette. The rectangles will remain selected, even though they are hidden.
@item Choose File | Export Bitmap and check the *Batch export 9 selected objects* box. Make sure that *Hide all except selected* is unchecked. click *Export*. This will create PNG files in the same directory as the drawing, named after the slices. These can now be used for a styled box in a GRUB theme.
@end enumerate
@section Theme File Manual
The theme file is a plain text file. Lines that begin with ``#`` are ignored
and considered comments. (Note: This may not be the case if the previous line
ended where a value was expected.)
The theme file contains two types of statements:
@enumerate
@item Global properties.
@item Component construction.
@end enumerate
@subsection Global Properties
@subsection Format
Global properties are specified with the simple format:
@itemize
@item name1: value1
@item name2: "value which may contain spaces"
@item name3: #88F
@end itemize
In this example, name3 is assigned a color value.
@subsection Global Property List
@multitable @columnfractions 0.3 0.6
@item title-text @tab Specifies the text to display at the top center of the screen as a title.
@item title-font @tab Defines the font used for the title message at the top of the screen.
@item title-color @tab Defines the color of the title message.
@item message-font @tab Defines the font used for messages, such as when GRUB is unable to automatically boot an entry.
@item message-color @tab Defines the color of the message text.
@item message-bg-color @tab Defines the background color of the message text area.
@item desktop-image @tab Specifies the image to use as the background. It will be scaled to fit the screen size.
@item desktop-color @tab Specifies the color for the background if *desktop-image* is not specified.
@item terminal-box @tab Specifies the file name pattern for the styled box slices used for the command line terminal window. For example, ``terminal-box: terminal_*.png'' will use the images ``terminal_c.png`` as the center area, ``terminal_n.png`` as the north (top) edge, ``terminal_nw.png`` as the northwest (upper left) corner, and so on. If the image for any slice is not found, it will simply be left empty.
@end multitable
@subsection Component Construction
Greater customizability comes is provided by components. A tree of components
forms the user interface. *Containers* are components that can contain other
components, and there is always a single root component which is an instance
of a *canvas* container.
Components are created in the theme file by prefixing the type of component
with a '+' sign:
@code{ + label @{ text="GRUB" font="aqui 11" color="#8FF" @} }
properties of a component are specified as "name = value" (whitespace
surrounding tokens is optional and is ignored) where *value* may be:
@itemize
@item a single word (e.g., ``align = center``, ``color = #FF8080``),
@item a quoted string (e.g., ``text = "Hello, World!"``), or
@item a tuple (e.g., ``preferred_size = (120, 80)``).
@end itemize

@enumerate
@item Requires BIOS
@item Crashes because the memory at 0x0-0x1000 isn't available
@item EFI only
@item 32-bit and 64-bit EFI have different structures and work in different CPU modes so it's not possible to chainload 32-bit bootloader on 64-bit platform and vice-versa
@item Some modules may need to be disabled
@item Requires ACPI
@end enumerate
PowerPC and Sparc ports support only Linux. MIPS port supports Linux and multiboot2.
@chapter Boot tests
As you have seen in previous chapter the support matrix is pretty big and some of the configurations are only rarely used. To ensure the quality bootchecks are available for all x86 targets except EFI chainloader, Appleloader and XNU. All x86 platforms have bootcheck facility except ieee1275. Multiboot, multiboot2, BIOS chainloader, ntldr and freebsd-bootloader boot targets are tested only with a fake kernel images. Only Linux is tested among the payloads using Linux protocols.
