4 Features you cannot find in the doco as working, should be
5 mentioned here. This is an assorted collection of stuff that will be
6 done, might be done, or is an idea that I want to think about
8 Most of the items are marked in the code as well
9 Grep for TODO and ugh/ugr/urg.
12 . * rename 'staff_line_leading' (who is being lead where?) to
13 staff_space, interline; (or other meaningful name) and use throughout
16 [-> leading are the lead strips between the sticks (lines) of
17 typeface. ie. leading is vertical space --hwn]
19 . * move \version check to lexer.ll
20 . * junk delayed spanner breaking.
21 . * check dangling_scm_sym working.
22 . * revise pianobrace to put font stuff into Lookup

26 \context Staff \notes {
28 % accidential after bar
29 fis'4 % accidential should be here
35 % no bars at the beginning of alternative 1 and at the end of alternative 2

50 So how do I do what I want to do?
52 In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
53 ends on a pair of grace notes. Standard practice is to mark this with
54 a slur starting on the main note and ending on the grace note, so a
55 singer knows where to break the words.
57 In bar 26, there's a \p marker that should appear below the grace
60 In bar 27, there's a crescendo that's supposed to start at the start
61 of the grace notes and extend to the note after the grace notes.
63 How do I specify these?
65 How can I control whether a grace note takes its time from the note
66 before or the note after it (for the purposes of alignment with
68 . * / distance after 4/4 \key.
69 . * spanners from grace to normal ctxt
71 1. I got a vertical line where I asked for a decrescendo.
73 2. Slurs -- good to see some spacing between slurs and lyrics, but not
74 there's several times too much space.
76 3. Slurs with wrong slopes. Where a slur between two notes goes from the
77 head of one to the stem of another it can have the wrong slope:
84 The music goes down but the slur goes up (or vice versa). This looks
87 4. Lyrics and \fermata collide. I know that the TODO has lyrics and scripts
88 colliding; I'm just including it here because it's really an issue for me
89 with fermata. Other scripts aren't a problem for me, but sometimes I need
90 fermata on both sides of the staff (when sop and alto hold different notes,
91 for example). In fact it's not just scripts and lyrics: In a choirstaff,
92 scripts above the bass clef collide with scripts below the treble clef.
94 5. Sometimes lyrics extend past the right end of the staff. I guess that
95 this is a similar problem (if not another symptom of the same problem) as
96 one of the spacing bugs mentioned in the TODO.
98 6. The bar line at the beginning of an \alternative section has disappeared
101 7. When it's a tight fit to get all the notes in the first line, the first
102 note collides with the time signature. Is this the same as one of the
103 spacing bugs mentioned in the TODO?
105 .* 4. Lyrics and grace sections don't go too well together.
106 The words are aligned with the main note, not the start of the
107 grace note. This is usually wrong, but is sometimes right.
108 . * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
109 . * Rename illegal to invalid
112 - The Postscript output is still very experimental
114 - It is impossible to typeset two textual scripts that are stacked
115 on top of eachother and avoids note collisions and at the same
116 time are typeset with different textStyle. I tried to move around
117 the text_engraver and other engravers between Voice and Thread
118 but the granularity is not fine enough, the scripts have to
119 share the same engraver in order to be get correct vertical
120 position but than they cannot have different style.
121 In my opinion, all scripts that share the same staff, should
122 be stacked vertically, avoiding collisions with the notes
125 - I'd like to change the \repetitions command to Jan's suggested
126 syntax: \repeat "repeatsymbol" 2 {...}, but I'm not sure that
127 I understand the implementation of repeats well enough.
129 - The paper11/13/26 files have to be updated.

240 My wish list for lyrics. I dream of a time when I will have enough time to
241 become familiar enough with the source code to be able to implement some of
242 these myself, but I don't know when that will be, so I thought I'd "publish"
243 my suggestions in case someone else is in a position to give them some
244 priority. Otherwise, perhaps they could go on the todo list?
246 If any of these are already implemented, please let me what the syntax is to
249 1. Stanza numbering. Numbering at the beginning of a song with the number
250 set to the left of the first note. It would also be nice (but not as
251 important) to be able to have some form of automatic numbering at the
252 beginning of each new line. This would make it easier to follow songs with a
253 large number of stanzas.
255 3. Notes centred above/below lyrics rather than left-aligned.
257 4. It would be very nice to be able to build some kind of phrasing into the
258 lyrics of hymns, etc, so that the first words of a phrase are left aligned
259 with each other, the last words are right aligned, and the words in between
262 5. In a song, with (say) four stanzas and a chorus, it would be nice to be
263 able to vertically align the chorus midway between the staves.
265 6. It would be nice to be able to put vertical brackets either side of a
266 repeated section with different words for each repeat.

432 . * output header info to MIDI too.

467 > Would it be hard to add support for proper dynamics in MIDI output? I
468 > would really like to have this feature...
470 Concretely spoken, for dynamics you have to write a performer
471 (Dynamics_performer), that will take the input requests. If I
472 understand correctly, every MIDI note played must have its dynamic
473 strength set separately. That means the the Dynamics_performer must
474 set the strength of every Audio_note it finds. This means that one
475 has to modify existing Audio items. The best way of doing this is
476 with a broadcast/acknowledge process.
478 So the best way of handling this, is
480 1 supporting dynamic settings in Audio_note
482 2 Write a Dynamics_performer that will modify
483 any notes it finds to set appropriate strengths.
485 I'd say that the work involved is not hard, but you have to be fluent
486 with C++ and need some insight into the working of Notation Contexts
487 and friends. I guess I could do it in a day or so, but if you are not
488 so fluent with the inner workings of LilyPond, it could take you some
489 more time (A few more days?).
491 Please note, that I am *not* going to code this myself: my days are
492 valuable, and I think I have more interesting things to do than fixing
493 the MIDI output (I don't even have a soundcard). But I *do* want to help
