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 . * indent = 0.0 with linewidth=-1.0
14 . * header for PS enteredby = "bla <bla@bar.com>"
15 . * ps/lily.ps see comments.
16 . * didot / big point.
18 . * fix singleStaffBracket
19 . * declare performers in \midi
20 . * input/test/stem-spacing.ly: 12/4 touches first note
21 . * timesig: sometimes bottom digit too high
23 . * \shape 1st dim skipped?
24 . * turn slope-damping on/off
25 . * We need feta-din*.mf files for more sizes than 10.
26 . * fix dynamics decently, ie. use kerning & ligatures.
27 . * dots & rest collisions?
29 . * fix \mudelafile{} to have decent functionality
30 . * P.P.S. It can be cool in mudela-book to distinguish in
31 pre,postMudelaExample, whether MudelaExample is epsed or not: ( if
32 this fragment is floating eps, than 1, otherwise 2). say
33 preMudelaExample[eps]{}, and change it in document body sometimes.
35 . * junk _ in lyric mode for " "
36 . * Lyrics and scripts collide.
37 . * a note with a circle after it, meaning:
39 note + circle = note + 1/4 of its length
41 the circle is like a dot that's not filled in. for example, on
42 page three, the c-sharp on the second line should be a quarter with
43 a circle, not a quarter tied to a sixteenth. is this at all
45 . * grace_align_item -> stackingdir = left, weird placement.
46 . * tuplets that are written as "number : note", for example
47 "3 : [image of a half note here]". possible?
50 . * don't shorten stems/staffs closer to each other.
51 . * accidentals closer to note head
52 . * to space the staffs/staffgroups contained in the score.
56 . * \$ and $ identifier syntax in examples.
57 . * Y dimension units: staffspace vs. Point
60 . * Rhythmic_column and interaction stem/rhythmic_column/note_head/dots.
68 . * Morally pure LilyPond.
69 . * Remove non-free software links.
70 . * Remove meta article LilyPond.
71 . * break priority setting from SCM.
73 . * remove [] in favour of auto-beamer
74 . * hangOnClef with non-breakable clefs.
75 . * Aha, the problem is the new TeX code generation for changing fonts.

149 My wish list for lyrics. I dream of a time when I will have enough time to
150 become familiar enough with the source code to be able to implement some of
151 these myself, but I don't know when that will be, so I thought I'd "publish"
152 my suggestions in case someone else is in a position to give them some
153 priority. Otherwise, perhaps they could go on the todo list?
155 If any of these are already implemented, please let me what the syntax is to
158 1. Stanza numbering. Numbering at the beginning of a song with the number
159 set to the left of the first note. It would also be nice (but not as
160 important) to be able to have some form of automatic numbering at the
161 beginning of each new line. This would make it easier to follow songs with a
162 large number of stanzas.
164 2. Hyphens between syllables. At the moment there appears to be no easy way
165 to position a hyphen mid-way between the syllables it breaks.
167 3. Notes centred above/below lyrics rather than left-aligned.
169 4. It would be very nice to be able to build some kind of phrasing into the
170 lyrics of hymns, etc, so that the first words of a phrase are left aligned
171 with each other, the last words are right aligned, and the words in between
174 5. In a song, with (say) four stanzas and a chorus, it would be nice to be
175 able to vertically align the chorus midway between the staves.
177 6. It would be nice to be able to put vertical brackets either side of a
178 repeated section with different words for each repeat.

371 > Would it be hard to add support for proper dynamics in MIDI output? I
372 > would really like to have this feature...
374 Concretely spoken, for dynamics you have to write a performer
375 (Dynamics_performer), that will take the input requests. If I
376 understand correctly, every MIDI note played must have its dynamic
377 strength set separately. That means the the Dynamics_performer must
378 set the strength of every Audio_note it finds. This means that one
379 has to modify existing Audio items. The best way of doing this is
380 with a broadcast/acknowledge process.
382 So the best way of handling this, is
384 1 supporting dynamic settings in Audio_note
386 2 Write a Dynamics_performer that will modify
387 any notes it finds to set appropriate strengths.
389 I'd say that the work involved is not hard, but you have to be fluent
390 with C++ and need some insight into the working of Notation Contexts
391 and friends. I guess I could do it in a day or so, but if you are not
392 so fluent with the inner workings of LilyPond, it could take you some
393 more time (A few more days?).
395 Please note, that I am *not* going to code this myself: my days are
396 valuable, and I think I have more interesting things to do than fixing
397 the MIDI output (I don't even have a soundcard). But I *do* want to help
398 you or other people with implementing this, so if you need help, don't
