* 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
-. * Depracate Wordwrap
-. * rerun profile
-. * Break_req handling is silly (break_forbid () + \break fucks up.)
-. * script engraver
-. * HaraKiriStaffContext removes bar lines and doesn't remove
- staff margin text on removed staff lines.
-. * 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.

+. * note head on stem err msg in dutch.

+. * here's no difference at all in output. When either is jacked up to 7.0,
+everything works and matches up; when either is set just a bit above the
+default 5.0 (5.4 is what I was hoping to use), stems miss note heads. So
+it's some sort of a numerical (truncation/roundoff) problem.

-
-- 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
+. * Write script that uses --find-old-relative to do auto relativization.
-- 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
-What's old about absolute to relative conversion? Could maybe use for
-abc2ly, midi2ly?
.* Cleanups needed
-. * \$ and $ identifier syntax in examples.
-. * Junk ghost positioning objects eg, Script leans on Staffside
- leans on Staff.

+. * [c8. c16 c16 c16] in 6/8 timesig.

+. * autoBeamMelisma: if I explicitly beam notes in a staff with auto
+beaming disabled I would like to have these beams also to be
+melismatic.
+. * The stemLength property should affect also beamed stems.
. * staffside spanner (crescendo!) along with staffswitch.
-. * --- 2, margin notes don't work correctly for the pianostaff (in the
-following example, i expect the "piano" string to be centered
-vertically between the two staves):
-
-\score {
- \notes \context PianoStaff <
- \property PianoStaff.instrument = "Piano"
- \context Staff = treble {
- a b c

.* STUFF
. * We need feta-din*.mf files for more sizes than 10.
-. *
-- The syntax for chords looks clumsy with two different meanings of
- '-' and different syntax for separating modifiers from the tonic
- and from other modifiers. Why not use for example ':' between
- tonic and modifier and between the different modifiers?
-
-- 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
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 {}

. * do --safe for PS output?
. * msgfmt -o check?

-. * 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
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.
