-> The terms C-clef, G-clef, F-clef stand for the signs, being
-> mutated forms of a C, a G and an F.
->
-> The terms Violin Clef etc. stand for the signs being used in
-> special positions on the staff.
->
-> The G-clef-sign indicates g' on the line around which the
-> snake centers. It is a Violin Clef if it is centered around the
-> second line (from below), and a French Violin Clef if it is
-> centered around the lowest.
->
-> The C-clef indicates c' on the line that gets
-> 'pinched' by it. It is a Soprano, Mezzosoprano (English?), Alto, Tenor
-> and (don't remember exactly, maybe Baritone) Clef, depending on
-> the line (from highest to lowest).
->
-> The F-clef-sign indicates f on the line between
-> the two dots. If it's on the second line from above, it is called
-> Bass Clef. If it's on the middle line, it is called (maybe
-> Baritone) Clef too, because it indicates the same pitches as the
-> C-Clef on the highest line. So, you could write an Alto Clef by
-> putting the F-clef sign on the lowest line (but that's _very_
-> uncommon).
->
-> Sorry, this is written very messy because I'm in a hurry,
-> but I hope you understand what I want to say.

+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.

-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,
