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

210 . * Align_element::padding ?
211 . * use streambufs and iostream
212 to provide IO handling for TeX stream, mudela stream, data-file.

237 . * Musical_pitch (analogous to Duration and Rhythmic_req)
238 think about, analogous to pitch:
239 * { a4 a16 } c <-- duration of c?
240 * < a4 b8 > c <-- duration of c?
242 . * make sure all ex's have a mudela-version
243 . * do rest-collisions for Multi_measure_rests as well.
244 . * split error/warning in error/warning/non_fatal_error
245 . * add a Duration_convert member to Duration_iter to set parameters.
246 Junk global duration settings.

248 . * fix variable define/lookup parser global<->paper
249 . * fix title/instrument placements; see input/test/title.ly
250 . * <\voiceone c4. \voicetwo c4>
251 . * I'd like to change the \repetitions command to Jan's suggested
252 syntax: \repeat "repeatsymbol" 2 {...}, but I'm not sure that
253 I understand the implementation of repeats well enough.

385 . * output header info to MIDI too.
386 . * dump \header into easily parsable format.

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

465 < \multi 2; { \stem 1; <b c> } { <f as b> } >
468 . * merge key{item} & localkey{item}?
472 . * redo Notehead to allow digits as heads
