4 Features you cannot find in the documentation 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 we want to think about.
8 Most of the items are marked in the code as well
9 Grep -i for TODO, FIXME and ugh/ugr/urg.
12 . * use hash tabs iso. alist_ for elt property?
13 . * TODO: junk dstream output.
14 . * agressive type-checking for SCM stuff.
15 . * use "staff-space" and "half-space" iso interline,
16 staff_line_leading () etc.
17 . * why does Voice.beamQuantisation = #'none not work?
18 overriding in ly/params.ly works fine
21 . * make a TODO.texi, like http://www.gnu.org/software/guile/ideas.html
22 . * make this file understandable for 3rd parties.
23 . * \accepts -> \acceptedby
24 . * context in embedded SCM errors.
25 . * eradicate all VIRTUAL_COPY_CONS () macros ; use indexed creation,
28 ctor_dict["Score_element"]->clone_func (orig);
29 ctor_dict["Score_element"]->create_func ();
30 . * acc at tied note after linebreak.
31 . * fix font-naming and selecting
33 . * chord tonic: placement of accidental C#, Cb (from scm and C++)
34 . * note head on stem err msg in dutch.
35 . * why need to run -C mf twice?
36 . * here's no difference at all in output. When either is jacked up to 7.0,
37 everything works and matches up; when either is set just a bit above the
38 default 5.0 (5.4 is what I was hoping to use), stems miss note heads. So
39 it's some sort of a numerical (truncation/roundoff) problem.
41 . * fix #'margin-shape; setting indent to 0 with \shape fails
42 . * Fixed size staff/system heights;
43 . * ly2dvi : don't repeat opus if same.
44 . * hara kiri _8 clef.
47 . * fix or replace feta-accordion.mf
51 - if I change the property minVerticalAlign in a multi staff score with
52 lyrics the change affects the lyrics too. I would like the change to
55 - I would like to be able to influence the sloping of xtuplet brackets
57 - for one of my test scores containing a modern edition of an early
58 17'th century composition I have a leading measure containing the
59 orginal clefs and note values of the original composition. I use the
60 a"harmonic" and "diamond" note head styles for that measure and would
61 like to have the stems of these notes _centered_ on the notehead as in
62 the mensural music notation.
64 - after the leading measure in the above mentioned score I want a double
65 bar line fully drawn across the staves and after that keep to the
66 ChoirStaff bar line types in the rest of the scores
68 . * make all Feta (including dynamics) available to the user in
69 textual scripts. Examples: "D.S. al \coda", "\mf espress.".
70 . * Write script that uses --find-old-relative to do auto relativization.
74 . * \$ and $ identifier syntax in examples.
75 . * Key_engraver, Local_key_item
76 . * Think of comprehensive solution for "if (grace_b == self_grace_b_)"
77 . * String[String.length] doesn't trap.
78 . * Rhythmic_column and interaction stem/rhythmic_column/note_head/dots.
81 . * Lookup::text -> needs to be TeX independent.
82 . * junk Music_iterator::first_b_
85 . * half-sharps, half-flats
86 . * adaptive accidental spacing.
87 . * accidentals closer to note head
91 . * [c8. c16 c16 c16] in 6/8 timesig.
92 . * Rewrite Stem, Beam (hairy)
93 . * beams over barlines
94 . * Rests and beams don't work too well together. Example:
95 [ r8 g''16 des'] [r8 c16 a]
96 . * autoBeamMelisma: if I explicitly beam notes in a staff with auto
97 beaming disabled I would like to have these beams also to be
99 . * The stemLength property should affect also beamed stems.
100 . * staffside spanner (crescendo!) along with staffswitch.
101 . * * auto melismaBusy for beams.
108 . * sort out breve shapes.
109 . * \time forces keysig?
112 . * We need feta-din*.mf files for more sizes than 10.
113 . * align left edge of broken tuplet-spanner (have a test case?)
114 . * fix dynamics decently, ie. use kerning & ligatures.
115 . * key restorations & repeats
116 . * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
117 . *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
118 ends on a pair of grace notes. Standard practice is to mark this with
119 a slur starting on the main note and ending on the grace note, so a
120 singer knows where to break the words.
122 In bar 27, there's a crescendo that's supposed to start at the start
123 of the grace notes and extend to the note after the grace notes.
124 . * 4. Lyrics and grace sections don't go too well together.
125 The words are aligned with the main note, not the start of the
126 grace note. This is usually wrong, but is sometimes right.
128 . * repeats and partial measures.
129 . * rhythmic staff & accidentals.
130 . * use melismaBusy in Lyric context to typeset melismata correctly.
131 . * ly2dvi/lilypond logfile.
132 . * hang Item on Spanner
133 . * do --safe for PS output?
135 . * collision of lyrics with span_bars. See star-spangled.
136 . * It is impossible to typeset two textual scripts that are stacked
137 on top of eachother and avoids note collisions and at the same
138 time are typeset with different textStyle. I tried to move around
139 the text_engraver and other engravers between Voice and Thread
140 but the granularity is not fine enough, the scripts have to
141 share the same engraver in order to be get correct vertical
142 position but than they cannot have different style.
143 In my opinion, all scripts that share the same staff, should
144 be stacked vertically, avoiding collisions with the notes
148 . * don't shorten stems/staffs closer to each other.
149 . * to space the staffs/staffgroups contained in the score.
152 . * tuplets that are written as "number : note", for example
153 "3 : [image of a half note here]". possible?
154 . * a note with a circle after it, meaning:
156 note + circle = note + 1/4 of its length
158 the circle is like a dot that's not filled in. for example, on
159 page three, the c-sharp on the second line should be a quarter with
160 a circle, not a quarter tied to a sixteenth. is this at all
162 . * make dependencies () a virtual function.
163 . * deprecate hangOnClef.
164 . * Abstraction for engravers:
165 . * make "in-between" engraver (Tie)
166 . * make wide_spanner_engraver (line_group_spanner, staff_symbol)
167 . * store req -> element, element -> element causes for warnings
168 . * compulsory hshift
169 . * My wish list for lyrics. I dream of a time when I will have enough time to
170 become familiar enough with the source code to be able to implement some of
171 these myself, but I don't know when that will be, so I thought I'd "publish"
172 my suggestions in case someone else is in a position to give them some
173 priority. Otherwise, perhaps they could go on the todo list?
175 If any of these are already implemented, please let me what the syntax is to
178 1. Stanza numbering. Numbering at the beginning of a song with the number
179 set to the left of the first note. It would also be nice (but not as
180 important) to be able to have some form of automatic numbering at the
181 beginning of each new line. This would make it easier to follow songs with a
182 large number of stanzas.
184 3. Notes centred above/below lyrics rather than left-aligned.
186 4. It would be very nice to be able to build some kind of phrasing into the
187 lyrics of hymns, etc, so that the first words of a phrase are left aligned
188 with each other, the last words are right aligned, and the words in between
191 5. In a song, with (say) four stanzas and a chorus, it would be nice to be
192 able to vertically align the chorus midway between the staves.
194 6. It would be nice to be able to put vertical brackets either side of a
195 repeated section with different words for each repeat.
196 . * Give # lines in linebreaking.
198 . * rewrite context defs using Scheme
199 . * junk TeX specifics from internal code.
200 . * \selectmusic to cut pieces from music.
201 . * formatting of input stuff.
203 . * TODO: merge atom & molecule; make tree from molecule.
204 . * Align_element::padding ?
205 . * use streambufs and iostream
206 to provide IO handling for TeX stream, mudela stream, data-file.
207 . * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
208 . * fix partial measures in meaningful way.
209 . * uniformise recent feta contributions.

229 {\voicetwo cis,4 r r | r2. | r1 }> |
231 . * Musical_pitch (analogous to Duration and Rhythmic_req)
232 think about, analogous to pitch:
233 * { a4 a16 } c <-- duration of c?
234 * < a4 b8 > c <-- duration of c?
236 . * make sure all ex's have a mudela-version
237 . * do rest-collisions for Multi_measure_rests as well.
238 . * split error/warning in error/warning/non_fatal_error
239 . * add a Duration_convert member to Duration_iter to set parameters.
240 Junk global duration settings.
241 . * discourage breaking of slurs
242 . * fix variable define/lookup parser global<->paper
243 . * fix title/instrument placements; see input/test/title.ly
244 . * <\voiceone c4. \voicetwo c4>
245 . * I'd like to change the \repetitions command to Jan's suggested
246 syntax: \repeat "repeatsymbol" 2 {...}, but I'm not sure that
247 I understand the implementation of repeats well enough.
248 . * add mudela-book-doc source to webstie.
249 . * fix singleStaffBracket
251 . * partial -> anacrouse

263 . * junk nesting slurs
267 . * the bracket is ugly (wings are too parabolic, should be more circular)
268 . * versioning for Feta

379 . * output header info to MIDI too.
380 . * dump \header into easily parsable format.

412 > Would it be hard to add support for proper dynamics in MIDI output? I
413 > would really like to have this feature...
415 Concretely spoken, for dynamics you have to write a performer
416 (Dynamics_performer), that will take the input requests. If I
417 understand correctly, every MIDI note played must have its dynamic
418 strength set separately. That means the the Dynamics_performer must
419 set the strength of every Audio_note it finds. This means that one
420 has to modify existing Audio items. The best way of doing this is
421 with a broadcast/acknowledge process.
423 So the best way of handling this, is
425 1 supporting dynamic settings in Audio_note
427 2 Write a Dynamics_performer that will modify
428 any notes it finds to set appropriate strengths.
430 I'd say that the work involved is not hard, but you have to be fluent
431 with C++ and need some insight into the working of Notation Contexts
432 and friends. I guess I could do it in a day or so, but if you are not
433 so fluent with the inner workings of LilyPond, it could take you some
434 more time (A few more days?).
436 Please note, that I am *not* going to code this myself: my days are
437 valuable, and I think I have more interesting things to do than fixing
438 the MIDI output (I don't even have a soundcard). But I *do* want to help
439 you or other people with implementing this, so if you need help, don't

462 . * merge key{item} & localkey{item}?
466 . * redo Notehead to allow digits as heads
