+* GNU LilyPond TODO
+Features you cannot find in the documentation as working, should be
+mentioned here. This is an assorted collection of stuff that will be
+done, might be done, or is an idea that we want to think about.
+m
+Most of the items are marked in the code as well
+Grep -i for TODO, FIXME and ugh/ugr/urg.
+
+.* TODO
+. * use Rhythmic_head::position_i () for all Staff_referenced
+. * .po -> .pot.
+. * setting indent to 0 with \shape fails
+. * hara kiri _8 clef.
+. * junk -M ?
+. * mudela-book doco
+. * rerun profile
+. * fix or replace feta-accordion.mf
+. * fix configure with CFLAGS or LDFLAGS, try:
++ CFLAGS=-g LDFLAGS='-Wl,--warn-common' ./configure
++ configure will use them while testing the compiler, but they don't
++ appear in config.make
+
+. * Break_req handling is silly (break_forbid () + \break fucks up.)
+. * script engraver
+. * Chords:
+. * Bass/inversion pitch when not part of Chord
+Sometimes a series of changing chords will be blocked out over a static tone
+in the bass, usually this was referred to as a pedal tone (and it's been
+continued to be used, even in contemporary music). Another less frequently
+used practice is putting a non-chordal tone in the bass (that is not acting
+as a pedal tone) in order to create tension or make a more colorful sound.
+There are examples of this in the classsical literature, but its use is much
+more prevalent today. For example, the chord sequence Dm7 - Dm7/G is such a
+sequence, and the Dm7/G defies easy classification. Is it a G7(no 3rd)add
+9/11? Or is it a G7(no 3rd)add2/4? Or perhaps Dm7 add11? It's a heck of a
+lot easier to read to just leave it as Dm7/G!
+. * Diminished does not mean 5-
+When speaking of a chord, dimished can mean one of two things: A diminished
+triad or a dimished seventh chord (which is distinctly different from what's
+known as the 'half-diminished' chord). The triad is a root with a flat
+third and flat fifth, and is notated (at least in America, someone else will
+have to fill me in on other countries) as (using C as the root) Cdim, or Co.
+The diminished seventh has a root with a flat third, flat fifth, and a
+doubly flatted seventh (which is enharmonically equivalent to a sixth, and
+from which comes tons of confusion). It is usually notated as (again, using
+C as the root) Cdim7 or Co7.
+
+. * Mondrup:
+
+- I would like the possibility of forcing clef- and key- changes to be
+printed _after_ the new bar line
+
+- I would like an option to define the number of systems on which the
+score must be distributed. As it is now it seems that I may only
+influence that indirectly through the gourlay_maxmeasures property.
+
+- if I change the property minVerticalAlign in a multi staff score with
+lyrics the change affects the lyrics too. I would like the change to
+_only_ affect staves.
+
+- I would like to be able to influence the sloping of xtuplet brackets
+
+- for one of my test scores containing a modern edition of an early
+17'th century composition I have a leading measure containing the
+orginal clefs and note values of the original composition. I use the
+"harmonic" and "diamond" note head styles for that measure and would
+like to have the stems of these notes _centered_ on the notehead as in
+the mensural music notation.
+
+- after the leading measure in the above mentioned score I want a double
+bar line fully drawn across the staves and after that keep to the
+ChoirStaff bar line types in the rest of the scores
+
+- autoBeamMelisma: if I explicitly beam notes in a staff with auto
+beaming disabled I would like to have these beams also to be
+melismatic.
+
+. * make all Feta (including dynamics) available to the user in
+ textual scripts. Examples: "D.S. al \coda", "\mf espress.".

+. * ? -Q, --find-old-relative show all changes in relative syntax

+abc2ly, midi2ly?

+> {\voiceone''4. r8}

+. * sort out breve shapes.
+. * \time forces keysig?
+
+.* STUFF
+. * We need feta-din*.mf files for more sizes than 10.
+- Rests and beams don't work too well together. Example:
+ [ r8 g''16 des'] [r8 c16 a]
+
+- The stemLength property should affect also beamed stems.
+
+. * align left edge of broken tuplet-spanner (have a test case?)
+. * fix dynamics decently, ie. use kerning & ligatures.
+. * key restorations & repeats
+. * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
+. * * auto melismaBusy for beams.
+. *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
+ends on a pair of grace notes. Standard practice is to mark this with
+a slur starting on the main note and ending on the grace note, so a
+singer knows where to break the words.
+
+In bar 27, there's a crescendo that's supposed to start at the start
+of the grace notes and extend to the note after the grace notes.
+. * 5. Sometimes lyrics extend past the right end of the staff. I guess that
+this is a similar problem (if not another symptom of the same problem) as
+one of the spacing bugs mentioned in the TODO.
+. * 4. Lyrics and grace sections don't go too well together.
+ The words are aligned with the main note, not the start of the
+ grace note. This is usually wrong, but is sometimes right.
+. * decimal point in \paper {}
+. * tie-direction
+. * repeats and partial measures.
+. * rhythmic staff & accidentals.
+. * use melismaBusy in Lyric context to typeset melismata correctly.
+. * ly2dvi/lilypond logfile.
+. * hang Item on Spanner
+. * do --safe for PS output?
+. * msgfmt -o check?
+. * collision of lyrics with span_bars. See star-spangled.
+. * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
+. * It is impossible to typeset two textual scripts that are stacked
+ on top of eachother and avoids note collisions and at the same
+ time are typeset with different textStyle. I tried to move around
+ the text_engraver and other engravers between Voice and Thread
+ but the granularity is not fine enough, the scripts have to
+ share the same engraver in order to be get correct vertical
+ position but than they cannot have different style.
+ In my opinion, all scripts that share the same staff, should
+ be stacked vertically, avoiding collisions with the notes
+ in all voices.
+
+. * break priority setting from SCM.
+. * Matanya's tips:
+. * don't shorten stems/staffs closer to each other.
+. * accidentals closer to note head
+. * to space the staffs/staffgroups contained in the score.
+. * heavier beams?
+
+. * tuplets that are written as "number : note", for example
+ "3 : [image of a half note here]". possible?
+. * a note with a circle after it, meaning:
+
+ note + circle = note + 1/4 of its length
+
+ the circle is like a dot that's not filled in. for example, on
+ page three, the c-sharp on the second line should be a quarter with
+ a circle, not a quarter tied to a sixteenth. is this at all
+ possible with lily?
+. * scm-ify \property values.
+. * make dependencies () a virtual function.
+. * deprecate hangOnClef.
+. * Abstraction for engravers:
+. * make "in-between" engraver (Tie)
+. * make wide_spanner_engraver (line_group_spanner, staff_symbol)
+. * store req -> element, element -> element causes for warnings
+. * compulsory hshift
+. * My wish list for lyrics. I dream of a time when I will have enough time to
+become familiar enough with the source code to be able to implement some of
+these myself, but I don't know when that will be, so I thought I'd "publish"
+my suggestions in case someone else is in a position to give them some
+priority. Otherwise, perhaps they could go on the todo list?
+
+If any of these are already implemented, please let me what the syntax is to
+use them!
+
+1. Stanza numbering. Numbering at the beginning of a song with the number
+set to the left of the first note. It would also be nice (but not as
+important) to be able to have some form of automatic numbering at the
+beginning of each new line. This would make it easier to follow songs with a
+large number of stanzas.
+
+3. Notes centred above/below lyrics rather than left-aligned.
+
+4. It would be very nice to be able to build some kind of phrasing into the
+lyrics of hymns, etc, so that the first words of a phrase are left aligned
+with each other, the last words are right aligned, and the words in between
+are centred.
+
+5. In a song, with (say) four stanzas and a chorus, it would be nice to be
+able to vertically align the chorus midway between the staves.
+
+6. It would be nice to be able to put vertical brackets either side of a
+repeated section with different words for each repeat.

+> Would it be hard to add support for proper dynamics in MIDI output? I
+> would really like to have this feature...
+
+Concretely spoken, for dynamics you have to write a performer
+(Dynamics_performer), that will take the input requests. If I
+understand correctly, every MIDI note played must have its dynamic
+strength set separately. That means the the Dynamics_performer must
+set the strength of every Audio_note it finds. This means that one
+has to modify existing Audio items. The best way of doing this is
+with a broadcast/acknowledge process.
+
+So the best way of handling this, is
+
+ 1 supporting dynamic settings in Audio_note
+
+ 2 Write a Dynamics_performer that will modify
+ any notes it finds to set appropriate strengths.
+
+I'd say that the work involved is not hard, but you have to be fluent
+with C++ and need some insight into the working of Notation Contexts
+and friends. I guess I could do it in a day or so, but if you are not
+so fluent with the inner workings of LilyPond, it could take you some
+more time (A few more days?).
+
+Please note, that I am *not* going to code this myself: my days are
+valuable, and I think I have more interesting things to do than fixing
+the MIDI output (I don't even have a soundcard). But I *do* want to help
+you or other people with implementing this, so if you need help, don't
+hesitate to ask.

-> And the smob and the C++ class are interlinked? Like
->
-> class Foo_class {
-> Foo_smob *smob_ptr_;
-> }
->
-> struct Foo_smob {
-> Foo_class *class_ptr_
-> }
-
-Usually you can get away without having this interlinked structure.
-One piece of information you need when exporting objects to scheme is
-the smob tag for your class. You might store this value (a long) into
-a class static variable, or a file static variable. I'll use a class
-static variable in this example.
-
-I typically use code that works like this (untested code ahead):
-
-class Foo_class {
- static long *Foo_smob_tag;
- SCM obj; // representation as a scheme object, description comes later
-}
-
-// call this once on startup
-void init_Foo_class {
- static scm_smobfuns type_rec;
-
- type_rec.mark = foo_mark;
- type_rec.free = foo_free;
- type_rec.print = foo_display;
- type_rec.equalp = 0;
- Foo_class::Foo_smob_tag = new int(scm_new_smob(type_rec));
-}
-
-When you want to export an object to scheme, you put a pointer to the
-object itself in the cdr of the cell, and the tag in the car of the
-cell. The code looks like this:
-
-// Is this a Foo?
-static int
-foo_p(SCM obj)
-{
- return(SCM_NIMP(obj) && SCM_CAR(obj) == Foo_class::Foo_smob_tag);
-}

-> C++ determines life time, so what is the strategy?
-
-What happens now when the destructor gets called? Lets set the cdr to
-NULL, and then check for that in all of the primitive functions that
-use your smob. We'll call this notion 'live'; a scheme object is
-'live' if the C++ representation still exists, it's dead if the C++
-object is gone. You can still have references to dead objects in
-scheme code; it's just an error to use them. This idea is stolen from
-Emacs's handling of buffers ('buffer-live-p' and friends).
-
-Add another function, foo_live_p:
-
-static int
-foo_live_p(SCM obj)
-{
- return(foo_p(obj) && SCM_CDR(obj) != NULL);
-}
-
-In you destructor, you need to do:
-
-~Foo_class()
-{
- SCM_CDR(this->obj, NULL);
-}
-
-When writing new primitives, now just check foo_live_p().
-
-I hope the above helps,
