-@unnumberedsubsec
-
-Music notation is composed of a sets of interrelated glyphs. In
-Lilypond every glyph usually is represented by one object, a so-called
-Graphic Object. The primary relations between graphic objects involve
-positions:
-
-@itemize @asis
-@item consecutive notes are printed left to right, grouped in a staff
-@item simultaneous notes are horizontally aligned (internally grouped in
-a paper column).
-@item the staccato mark is horizontally centered on the note it applies
-to.
-@end itemize
-
-The abstract encoding of such relations is done with the concept
-@dfn{reference point}. The reference point (in X direction) of the
-staccato mark is the note it applies to. The (X) position of the
-staccato mark is stored relative to the position of the note head. This
-means that the staccato will always maintain a fixed offset wrt to the
-note head, whereever the head is moved to.
-
-In the same vein, all notes on a staff have their Y positions stored
-relative to an object that groups the staff. If that object is moved,
-the absolute Y positions of all objects in that spanner change along, in
-effect causing the staff and all its contents to move as a whole.
-
-Each graphic object stores a pointer and an relative offset for each
-direction: one for the X-axis, one for the Y-axis. For example, the X
-parent of a Note_head usually is a Note_column. The X parent of a
-Note_column usually is either a Collision or a Paper_column. The X
-parent of a Collision usually is a Paper_column. If the Collision
-moves, all Note_heads that have that Collision as parent also move, but
-the absolute position of the Paper_column does not change.
-
-To build a graphical score with Graphic_elements, conceptually, one
-needs to have one Root object (in Lilypond: Line_of_score), and
-recursively attach objects to the Root. However, due to the nature
-of the context selection mechanisms, it turns out to be more
-advantageous to construct the tree the other way around: first small
-trees (note heads, barlines etc.) are created, and these are
-subsequently composed into larger trees, which are finally hung on a
-Paper_column (in X direction) or Line_of_score (in Y direction).
-
-The structure of the X,Y parent relations are determined by the
-engravers and notation contexts:
-
-The most important X-axis parent relation depends on the timing: notes
-that come earlier are attached to Paper_column that will be positioned
-more to the left.
-
-The most important Y-axis relation depends on containment of contexts:
-notes (created in a Thread or Voice context) are put in the staff where
-the originating context lives in.
-
-Graphical_axis_groups are special graphic objects, that are designed to
-function as a parent. The size of a Graphical_axis_groups group is the
-union of its children.
-
-@node Position and width Callbacks, , , Backend
-@unnumberedsubsec
-
-The positions are, as explained relative to a parent reference
-point. Most positions are not known when an object is created, so these
-are calculated as needed. This is done by adding a callback for a
-specific direction, eg
-
-@example
- Real
- my_translate (Score_element * ptr, Axis a)
- @{
- return 5.0 PT;
- @}
-
- [..]
- my_element->add_offset_callback (my_translate, Y_AXIS)
-@end example
-
-When a call is made to @code{my_element->relative_position (obj,
-Y_AXIS)}, @code{my_translate} will be called. The result is that
-my_element will be translated up by 5 pt. There are numerous callbacks,
-for example
-@itemize @bullet
-@item to offset element by staff-spaces (See class
-@code{Staff_symbol_referencer}).
-@item to align elements next to other groups of elements (See class
-@code{Side_position_interface})
-@item to
-@end itemize
-
-Offset callbacks can be stacked. The callbacks will be executed in the
-order that they were added.
-
-Width and height are similarly implemented using extent callbacks. There
-can be only one callback for each axis. No callback (the 0 ptr) means:
-"empty in this direction".
-
-@node Score_element properties, , , Backend
-@unnumberedsubsec
-
-Score elements can have other properties besides positioning, for
-example, text strings (for text objects) style settings, glyphs, padding
-settings (for scripts). These settings are stored in element properties.
-
-Properties are stored as GUILE association lists, with symbols as keys.
-Element properties can be accessed using the C++ functions
-
-@example
- SCM get_elt_property (SCM) const;
- void set_elt_property (const char * , SCM val);
- void set_immutable_elt_property (const char * , SCM val);
- void set_immutable_elt_property (SCM key, SCM val);
- void set_elt_property (SCM , SCM val);
- void set_elt_pointer (const char*, SCM val);
- SCM remove_elt_property (const char* nm);
-@end example
-
-All lookup functions identify undefined properties with GUILE
-end-of-list (ie. @code{'()} in Scheme or @code{SCM_EOL} in C)
-
-Implementation wise, there are two kinds of properties:
-
-@itemize @bullet
-@item mutable properties:
-element properties that change from object to object. The storage of
-these are private to a Score element. Typically this is used to store
-lists of pointers to other objects
-
-@item immutable properties:
-element properties that are shared across objects. The storage is
-shared, and hence is read-only. Typically, this is used to store
-function callbacks, and values for shared element properties are read
-from @file{ly/engraver.ly}.
-
-
-
-The following is from lily 1.3.80, and it shows the settings for the bar
-numbers: Bar numbers are breakable, and visible at the beginning of the
-line. The setting for @code{molecule-callback} indicates that Bar_number
-is implemented as a text.
-@example
- basicBarNumberProperties = #`(
- (molecule-callback . ,Text_item::brew_molecule)
- (breakable . #t)
- (visibility-lambda . ,begin-of-line-visible)
- )
-@end example
-@end itemize
-
-
-In 1.3.81 an music expression was added to add to the immutable property
-list, eg. like this:
-
-@example
- \pushproperty #'(basicBarNumberProperties)
- #'visibility-lambda #end-of-line-visible
-@end example
-
-This will add the entry @code{`(visibility-lambda .
-,end-of-line-visible)} to the immutable property list for bar numbers,
-in effect overriding the setting from @file{ly/engraver.ly}. This can be
-undone as follows
-
-@example
- \popproperty #'(basicBarNumberProperties)
- #'visibility-lambda
-@end example
-
-Note that you must accompany these statements with a proper context
-selection in most cases.

-[FIXME: we want to get rid of dependencies in the implementation.]
-
-Besides relative positions there are lots of other relations between
-elements. Lilypond does not contain other specialized relation
-management (Like the relative positioning code). Instead, objects can
-be connected through dependencies, which sets the order in which objects
-are to be processed.
-
-Example: the direction of a beamed stem should equal the direction of
-the beam. When the stem is a added to the beam, a dependency on the
-beam is set in the stem: this means that @code{Beam::do_pre_processing
-()} (which does various direction related things) will be called before
-@code{Stem::do_pre_processing ()}.
-
-The code that manages dependencies resides in the class
-@code{Score_element}, a derived class of @code{Graphical_element}. The
-bulk of the code handles line breaking related issues.
-
-To sketch the problems with line breaking: suppose a slur spans a line
-break,
-@example
-
-c4( c'''' c | \break d d )d
-
-@end example
-In this case, the slur will appear as two parts, the first part spanning
-the first three notes (the @code{c}s), the second spanning the last
-three (the @code{d}s). Within Lilypond this is modeled as breaking the
-slur in parts: from the Original slur, two new clones of the old slur
-are made. Initially both clones depend on the six notes. After the
-hairy code in Score_element, Spanner and Item which does substitutions
-in sets of dependencies, the first clone depends on the first three
-notes, the second on the last three.
-
-The major derived classes of Score_element are Item and Spanner.
-An item has one horizontal position. A spanner hangs on two items.
-
-@node Items, , , Backend
-@section Items
-
-
-
-An item is a score element that is associated with only one
-Paper_column. Examples are note heads, clefs, super and superscripts, etc.
-Item is a derived class of Score_element.
-
-The shape of an item is known before the break calculations, and line
-spacing depends on the size of items: very wide items need more space
-than very small ones.
-
-An additional complication is the behavior of items at linebreaks. For
-example, when you do a time signature change, you get only one symbol.
-If it occurs at a linebreak, the new time signature must be printed both
-before and after the linebreak. Other `breakable symbols' such as
-clefs, and bar lines also exhibit this behavior.
-
-if a line of music is broken, the next line usually gets a clef. So in
-TeX terms, the clef is a postbreak. The same thing happens with meter
-signs: Normally the meter follows the bar. If a line is broken at that
-bar, the bar along with the meter stays on the "last" line, but the next
-line also gets a meter sign after the clef. To support this,
-breakable items are generated in the three versions: original
-(unbroken), left (before line break) and right (after line break).
-During the line spacing, these versions are used to try how the spacing
-of a line works out.
-
-Once the definitive spacing is determined, dependencies (and various
-other pointers) are substituted such that all dependencies point at the
-active items: either they point at the original, or they point at left
-and right.
-
-@node Spanners, , , Backend
-@section Spanners
-
-Spanners are symbols that are of variable shape, eg. Slurs, beams, etc.
-Spanners is a derived class of Score_element.
-
-The final shape can only be determined after the line breaking process.
-All spanners are spanned on two items, called the left and right
-boundary item. The X reference point is the left boundary item.
-
-
-@node Future work, , , Backend
-@section Future work
-
-There are plans to unify Spanner and Item, so there will no longer be
-such a clear distinction between the two. Right now, Score_elements are
-always either Item or either Spanner.

@node Grobs, , , Reference Manual
+@section Grobs
This section is about Grobs (short for Graphical Objects), which are
formatting objects used to create the final output. This material is
them involve Grobs in some form, this section explains some details of
how grobs work.
-Types of grob?
+@menu
+* What is a grob?::
+* Callbacks::
+* Setting grob properties::
+* Items and Spanners::
+* Pointer substitution::
+@end menu
+
+@node What is a grob?, , , Grobs
+
+All grobs have an X and Y-position on the page. These X and Y positions
+are stored in a relative format, so they can easily be combined by
+stacking them, hanging one grob to the side of another, and coupling
+them into a grouping-grob.
+
+Each grob has a reference point, or parent: the position of a grob is
+stored relative to that reference point. For example the X-reference
+point of a staccato dot usually is the note head that it applies
+to. Whenever the note head is moved, the staccato dot moves along
+automatically.
+
+If you keep following offset reference points, you will always end up at
+the root-object. This root object is called @code{Line_of_score}
+@ref{(lilypond-internals)Element Line_of_score}, and it represents a
+system (ie. a line of music).
+
+All grobs carry a set of grob-properties. In the Stem example above,
+the property @code{direction} is set to value @code{1}. The function
+that draws the symbol (@code{Stem::brew_molecule}) uses the value of
+@code{direction} to determine how to print the stem and the flag. The
+appearance of a grob is determined solely by the values of its
+properties.
+
+Often, a grob also is associated with a symbol. On the other hand, Some
+grobs do not print any symbols, but take care of grouping objects. For
+example, there is a separate grob that stacks staffs vertically, so they
+are not printed in overstrike. The NoteCollision @ref{(lilypond-internals)Element
+NoteCollision} is another example of an abstract grob. It only moves
+around chords, but doesn't print anything.
+
+A complete list of grob types is found in @ref{(lilypond-internals)Elements}
+
+Grobs are created in the "Interpreting music" phase, by things in
+LilyPond called engravers. In this phase of the translation, a load of
+grobs are created, and they are linked into a giant network of objects.
+This network of grobs forms the "specification" of the print
+problem. This problem is then solved: configurations, directions,
+dimensions, line breaks, etc. are calculated. Finally, the printing
+description in the form of Molecules (@ref{Molecule}) is extracted from
+the network. These are then dumped into the output file
+
+@node Callbacks, , , Grobs
+
+Offsets of grobs are relative to a parent reference point. Most
+positions are not known when an object is created, so these are
+calculated as needed. This is done by adding a callback for a specific
+direction.
+
+Suppose you have the following code in a .ly file.
+@example
+ #(define (my-callback gr axis)
+ (* 2.0 (get-gr-property grob 'direction))
+ )
+
+....
+
+ \property Voice.Stem \override #'Y-offset-callbacks = #(list
+ my-callback)
+@end example
+
+When the Y-offset of a Stem object is needed, LilyPond will
+automatically execute all callbacks for that object. In this case, it
+will find @code{my-callback}, and execute that. The result is that the
+stem is translated by two staff spaces in its direction.
+
+(note: Y-offset-callbacks is also a property)
+
+
+Offset callbacks can be stacked, ie.
+
+@example
+ \property .... \override #'Y-offset-callbacks = #(list
+ callback1 callback2 callback3)
+
+@end example
+
+The callbacks will be executed in the order callback3 callback2
+callback1. This is used for quantized positioning: the staccato dot is
+above or below a note head, and it must not be on a staff-line.
+
+To achieve this, for the staccato there are two callbacks: one callback
+that positions the grob above or below the note head, and one callback
+that rounds the Y-position of the grob to the nearest open space.
+
+Similarly, the size of a grob are determined through callbacks, settable
+with grob properties @code{X-extent-callback} and @code{Y-extent-callback}.
+There can be only one extent-callback for each axis. No callback (value #f)
+means: "empty in this direction". If you fill in a pair, that pair
+hard-codes the extent in that coordinate.
+
+
+@node Setting grob properties, , , Grobs
+
+Grob properties are stored as GUILE association lists, with symbols as
+keys. From C++, element properties can be accessed using the functions
+
+@example
+ SCM get_grob_property (SCM) const;
+ void set_grob_property (const char * , SCM val);
+ void set_immutable_grob_property (const char * , SCM val);
+ void set_immutable_grob_property (SCM key, SCM val);
+ void set_grob_property (SCM , SCM val);
+ void set_grob_pointer (const char*, SCM val);
+ SCM remove_grob_property (const char* nm);
+@end example
+
+In GUILE, LilyPond provides
+
+@example
+ ly-get-grob-property GROB SYMBOL
+ ly-set-grob-property GROB SYMBOL VALUE
+@end example
+
+All lookup functions identify undefined properties with
+end-of-list (ie. @code{'()} in Scheme or @code{SCM_EOL} in C)
+
+Properties are stored in two ways:
+@itemize @bullet
+@item mutable properties:
+element properties that change from object to object. The storage of
+these are private to a grob. Typically this is used to store lists of
+pointers to other grobs
+
+@item immutable properties:
+element properties that are shared across different grobs of the same
+type. The storage is shared, and hence it is read-only. Typically, this
+is used to store function callbacks, and values for shared element
+properties are read from @file{scm/element-description.scm}.
+@end itemize
+
+There are two ways to manually set grob properties.
+
+You can change immutable grob properties. This is done with the
+\override syntax:
+
+@example
+ \property Voice.Stem \override #'direction = #1
+@end example
+
+This will push the entry @code{'(direction . 1)} on the immutable
+property list for stems, in effect overriding the setting from
+@file{scm/element-description.scm}. This can be undone by
+
+@example
+ \property Voice.stem \revert #'direction
+@end example
+
+If you use this a lot, this gets old quickly. So we also have a
+shorthand,
+
+@example
+ \property Context.GrobType \set #'prop = #VAL
+@end example
+
+this does a @code{\revert} followed by a @code{\override}
+
+The second way is \outputproperty. This construct looks like
+
+@example
+ \context ContextName \outputproperty @var{pred} #@var{sym} = #@var{val}
+@end example
+
+In this case, in every grob that satisfies @var{pred}, the property
+assignment @var{sym} = @var{val} is done. For example
+
+@example
+ \outputproperty
+ #(lambda (gr) (string? (ly-get-grob-property gr
+ 'text)))
+ #'extra-offset = #'(-1.0 . 0.0)
+@end example
+
+This shifts all elements that have a @code{text} property one staff
+space to the left.
+
+@node Items and Spanners, , , Grobs
-What is a grob?
+Grobs can also be distinguished in their role in the horizontal spacing.
+A lot of grobs define constraints on the spacing by their sizes. For
+example, note heads, clefs, stems, and all other symbols with a fixed
+shape. These grobs form a subtype called @code{Item}.
-Where do they come from?
+Other grobs have a shape that depends on the horizontal spacing. For
+example, slur, beam, tie, etc. These grobs form a subtype called
+@code{Spanner}. All spanners have two span-points (these must be
+@code{Item}s), one on the left and one on the right. The left bound is
+also the X-reference point.
-How can you override?
+Some items need special treatment for line breaking. For example, a
+clef is normally only printed at the start of a line (ie. after a line
+break). To model this, `breakable' items (clef, key signature, bar lines,
+etc.) are copied twice. Then we have three versions of each breakable
+item: one version if there is no line break, one version that is printed
+before the line break (at the end of a system), one version that is
+printed after the line break.
-Items and Spanners?
+Whether these versions are visible and take up space, is determined by
+the outcome of the visibility-lambda. This is a function taking a
+direction (-1, 0 or 1) and returns a cons of booleans, signifying wether
+this grob should be transparent and invisible.
-X and Y parents, offsets and extents.
