New in 1.99:
* Keyboard layouts support.
* New `lsapm' command (i386-pc only).
* Parser for GRUB Legacy configuration files.
* Support RAID on virtio devices.
* Remove deprecated `root' command.
* New `euro.pf2' font which supports most European languages.
* Avoid opening the same device twice on Open Firmware platforms.
* Extend `vbeinfo' and `vbetest' commands to non-VBE graphics, as
`videoinfo' and `videotest'.
* New `lsefisystab', `lssal', and `lsefimmap' commands on EFI platforms.
* Support explicit user claim that a device is BIOS-visible. Devices
listed in device.map will be assumed to be readable using only BIOS
facilities, rather than anything more complex such as LVM or RAID.
* New bash-completion script for GRUB utilities.
* Use ACPI to shut down if possible.
* New `lsacpi' command.
* Basic btrfs support (detection and UUID).
* New `--boot-directory' option to `grub-install', `grub-reboot', and
`grub-set-default', with clearer semantics than the previous
`--root-directory' option.
* Rename CD-ROM device to "cd" on BIOS platforms.
* Transparent decompression filters.
* Simpler PXE image generation. New `grub-mknetdir' utility to generate
netboot directory trees.
* New relocator. Allows for more kernel support and more
straightforward loader writing.

* `grub-mkrescue' support for EFI, coreboot, and QEMU platforms.
* Unify `grub-mkimage' source code across platforms.
* Unify `grub-mkimage', `grub-setup', and `grub-install' source code
across platforms.
* Fix VGA (as opposed to VBE) video driver, formerly a terminal driver.
@ -83,8 +126,9 @@ New in 1.99:
* sunpc partition table support.
* Add a number of new language features to GRUB script: `for', `while',
`until', `elif', function parameters, `break', `continue', and
`shift'.
`until', `elif', function parameters, `break', `continue', `shift',
multi-line quoted strings, positional parameters with `setparams',
`return', filename wildcard expansion, and `!'.
* Support nested partition tables. GRUB now prefers to name partitions
in the form `(hd0,msdos1,bsd1)' rather than `(hd0,1,a)'.

/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
for FUNCTION which will then trigger a compiler warning containing
the text of "literal string" anywhere that function is called, if
supported by the compiler. If the compiler does not support this
feature, the macro expands to an unused extern declaration.
This macro is useful for marking a function as a potential
portability trap, with the intent that "literal string" include
instructions on the replacement function that should be used
instead. However, one of the reasons that a function is a
portability trap is if it has the wrong signature. Declaring
FUNCTION with a different signature in C is a compilation error, so
this macro must use the same type as any existing declaration so
that programs that avoid the problematic FUNCTION do not fail to
compile merely because they included a header that poisoned the
function. But this implies that _GL_WARN_ON_USE is only safe to
use if FUNCTION is known to already have a declaration. Use of
this macro implies that there must not be any other macro hiding
the declaration of FUNCTION; but undefining FUNCTION first is part
of the poisoning process anyway (although for symbols that are
provided only via a macro, the result is a compilation error rather
than a warning containing "literal string"). Also note that in
C++, it is only safe to use if FUNCTION has no overloads.
For an example, it is possible to poison 'getline' by:
- adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
[getline]) in configure.ac, which potentially defines
HAVE_RAW_DECL_GETLINE
- adding this code to a header that wraps the system <stdio.h>:
#undef getline
#if HAVE_RAW_DECL_GETLINE
_GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
"not universally present; use the gnulib module getline");
#endif
It is not possible to directly poison global variables. But it is
possible to write a wrapper accessor function, and poison that
(less common usage, like &environ, will cause a compilation error
rather than issue the nice warning, but the end result of informing
the developer about their portability problem is still achieved):
#if HAVE_RAW_DECL_ENVIRON
static inline char ***rpl_environ (void) { return &environ; }
_GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
# undef environ
# define environ (*rpl_environ ())

@heading Built-in Commands
Some built-in commands are also provided by GRUB script to help script
writers perform actions that are otherwise not possible. For example, these
include commands to jump out of a loop without fully completing it, etc.
@table @asis
@item break [@code{n}]
Exit from within a @code{for}, @code{while}, or @code{until} loop. If
@code{n} is specified, break @code{n} levels. @code{n} must be greater than
or equal to 1. If @code{n} is greater than the number of enclosing loops,
all enclosing loops are exited. The return value is 0 unless @code{n} is
not greater than or equal to 1.
@item continue [@code{n}]
Resume the next iteration of the enclosing @code{for}, @code{while} or
@code{until} loop. If @code{n} is specified, resume at the @code{n}th
enclosing loop. @code{n} must be greater than or equal to 1. If @code{n}
is greater than the number of enclosing loops, the last enclosing loop (the
@dfn{top-level} loop) is resumed. The return value is 0 unless @code{n} is
not greater than or equal to 1.
@item return [@code{n}]
Causes a function to exit with the return value specified by @code{n}. If
@code{n} is omitted, the return status is that of the last command executed
in the function body. If used outside a function the return status is
false.
@item shift [@code{n}]
The positional parameters from @code{n}+1 @dots{} are renamed to
@code{$1}@dots{}. Parameters represented by the numbers @code{$#} down to
@code{$#}-@code{n}+1 are unset. @code{n} must be a non-negative number less
than or equal to @code{$#}. If @code{n} is 0, no parameters are changed.
If @code{n} is not given, it is assumed to be 1. If @code{n} is greater

@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

@item width
The width of object in same format.
@item height
The height of object in same format.
@item id
The identifier for the component. This can be any arbitrary string.
The ID can be used by scripts to refer to various components in the GUI
component tree. Currently, there is one special ID value that GRUB
recognizes:
@multitable @columnfractions 0.2 0.7
@item ``__timeout__`` @tab Any component with this ID will have its *text*, *start*, *end*, *value*, and *visible* properties set by GRUB when it is counting down to an automatic boot of the default menu entry.
