+
+* GNU LilyPond TODO
+Features you cannot find in the doco 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 I want to think about
+
+Most of the items are marked in the code as well
+Grep for TODO and ugh/ugr/urg.
+
+.* TODO before 1.2
+. * rename 'staff_line_leading' (who is being lead where?) to
+staff_space, interline; (or other meaningful name) and use throughout
+lily
+
+[-> leading are the lead strips between the sticks (lines) of
+typeface. ie. leading is vertical space --hwn]
+. * Rewrite \rhythm to be during interpreting.
+. * move \version check to lexer.ll
+. * junk delayed spanner breaking.
+. * core dump on broken (de)crescendo
+. * align left edge of broken (de)cresc/slur/tie/tuplet/volta
+. * check dangling_scm_sym working.
+. * spacing of accidentals
+. * key restorations & repeats
+. *
+So how do I do what I want to do?
+
+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 26, there's a \p marker that should appear below the grace
+note.
+
+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.
+
+How do I specify these?
+. * spanners from grace to normal ctxt
+. * Glen:
+
+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.
+. * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
+. * Rename illegal to invalid
+. * Mats:
+
+- The Postscript output is still very experimental
+
+- 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.
+
+- I'd like to change the \repetitions command to Jan's suggested
+ syntax: \repeat "repeatsymbol" 2 {...}, but I'm not sure that
+ I understand the implementation of repeats well enough.
+
+- The paper11/13/26 files have to be updated.
+. * Grace_slur_engraver.
+. * input/star-spangled-banner.ly: fold for lyrics?

+. * hangOnClef with non-breakable clefs.
+. * account for accidentals in spacing.
+. * collision of lyrics with span_bars. See star-spangled.
+. * fix partial measures in meaningful way.
+. * relative mode for midi2ly
+. *
+Crescendi/diminuendi that cross a line break lose their vertical
+position and all end up above the top staff line, see the
+following 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.

+. * 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.

+. * tempo change
+. * ornaments (and trills?)
+. * slurs
+. * accents
+. * dynamics
+> 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.
