+. * Aha, the problem is the new TeX code generation for changing fonts.
+> (The explanation below is mostly intended for Han-Wen and Jan)
+> Before, the font was changed with macros declared separately for
+> pure TeX and LaTeX, but now all the fonts are declared directly in
+> the generated code using the low-level TeX commands. This circumvents
+> the fontencoding mechanism of LaTeX and is a potential source of
+> problems also for us users of the Latin-1 character set.
+> I think it still works since the inputencoding latin1 is
+> declared by ly2dvi, but it still means that e.g. an o with
+> umlaut is typeset as a combination of the two symbols 'o' and
+> 'umlaut' instead of as a single character, as would be the case
+> if fontencoding OT1 had been used. This shouldn't give any
+> difference in layout, though. One of the main argument for using
+> fontencoding OT1 is for the hyphenation mechanism to work, an
+> argument that's clearly irrelevant in our application. Yet we
+> see the problem for August.
+. * Abstraction for engravers:

+. * make wide_spanner_engraver (line_group_spanner, staff_symbol)
+. * do scaled fonts generally

-. * How can I specify a chord whose duration is longer than a whole note?
- \type ChordNames { \chord{ A1*2-min } }
-
- gives me a parse error. And \times doesn't work either. I can't use
- a spacer note. So it seems to be impossible to have long chords of
- general length. Of course, in the example above I can use \breve.
- But what if I want a chord that lasts for 3 whole notes? Or what
- about 2.5 whole notes? Is there a mechanism for getting this kind of
- length?
-
-
- Why does my second extender request get junked in the following:
-
- \score{
- < \notes \relative c''{
- a4()b()c()d c()d()b()a }
- \type Lyrics \lyrics {
- foo1 __ bar2. __ _4 }
- > }
-
- It seems that \cr and \decr don't work any more.
-
- \score{
- \notes{
- a \cr b \rc c }
- \paper{linewidth=-1.;}
- }
-
- Gives me
-
- qq.ly:3:9: warning: can't find (de)crescendo to end:
- a \cr
- b \rc c }
-
-
-
- Use of semicolons is still rather confusing. They are obligatory
- after some types of assignments and illegal after others.
-
- \property foo=bar illegal
- foo = 3 at top level illegal
- foo = 3 inside \paper obligatory
- foo = \notes{ ...} top level illegal
- foo = \translator{ } in \paper obligatory
-
- As far as I can tell, the sole accomplishment of this syntactic
- irregularity is to keep the user as confused as possible.
-
-
- I was trying to get interstaff beams to work and did this:

- \translator Staff=one

- \translator{
- \GrandStaffContext
- minVerticalAlign = 3.0*\staffheight;
- maxVerticalAlign = 3.0*\staffheight;
- }
- linewidth = -1.;
- }

+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.
+
+2. Hyphens between syllables. At the moment there appears to be no easy way
+to position a hyphen mid-way between the syllables it breaks.
+
+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.

- 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);
- }
- // given a Scheme representation, return, a C++ representation
- static Foo_class *
- foo_unbox(SCM obj)
- {
- return((Foo_class*)SCM_CDR(obj));
- }
- // the SCM representation of the object is stored inside itself
- // this will become useful when destructor gets called
- static SCM
- foo_box(Foo_class *foo)
- {
- SCM_DEFER_INTS;
- SCM_NEWCELL(foo->obj);
- SCM_SETCAR(foo->obj, Foo_class::Foo_smob_tag);
- SCM_SETCDR(foo->obj, (SCM)foo);
- SCM_ALLOW_INTS;
- return foo->obj;
- }
- > 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,

- I use the following, which should definitely be provided somewhere
- in guile, but isn't, AFAIK:
- (define (hash-table-for-each fn ht)
- (do ((i 0 (+ 1 i)))
- ((= i (vector-length ht)))
- (do ((alist (vector-ref ht i) (cdr alist)))
- ((null? alist) #t)
- (fn (car (car alist)) (cdr (car alist))))))
- (define (hash-table-map fn ht)
- (do ((i 0 (+ 1 i))
- (ret-ls '()))
- ((= i (vector-length ht)) (reverse ret-ls))
- (do ((alist (vector-ref ht i) (cdr alist)))
- ((null? alist) #t)
- (set! ret-ls (cons (fn (car (car alist)) (cdr (car alist))) ret-ls)))))
- If you want a C version, you can run the above code through hobbit, or
- tranlate it to C by hand.
