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 Rhythmic_head::position_i () for all Staff_referenced
15 . * web: download link.
17 . * Break_req handling is silly (break_forbid () + \break fucks up.)
20 . * HaraKiriStaffContext removes bar lines and doesn't remove
21 staff margin text on removed staff lines.
24 - I would like the possibility of forcing clef- and key- changes to be
25 printed _after_ the new bar line
27 - I would like an option to define the number of systems on which the
28 score must be distributed. As it is now it seems that I may only
29 influence that indirectly through the gourlay_maxmeasures property.
31 - if I change the property minVerticalAlign in a multi staff score with
32 lyrics the change affects the lyrics too. I would like the change to
35 - I would like to be able to influence the sloping of xtuplet brackets
37 - for one of my test scores containing a modern edition of an early
38 17'th century composition I have a leading measure containing the
39 orginal clefs and note values of the original composition. I use the
40 "harmonic" and "diamond" note head styles for that measure and would
41 like to have the stems of these notes _centered_ on the notehead as in
42 the mensural music notation.
44 - after the leading measure in the above mentioned score I want a double
45 bar line fully drawn across the staves and after that keep to the
46 ChoirStaff bar line types in the rest of the scores
48 - autoBeamMelisma: if I explicitly beam notes in a staff with auto beaming disabled I
49 would like to have these beams also to be melismatic.
51 . * make all Feta (including dynamics) available to the user in
52 textual scripts. Examples: "D.S. al \coda", "\mf espress.".
54 . * ? -Q, --find-old-relative show all changes in relative syntax
55 What's old about absolute to relative conversion? Could maybe use for
59 . * \$ and $ identifier syntax in examples.
60 . * Junk ghost positioning objects eg, Script leans on Staffside
64 . * center option (??)
65 . * make mudela-book understand usepackage{geometry}
66 . * Key_engraver, Local_key_item
67 . * Think of comprehensive solution for "if (grace_b == self_grace_b_)"
68 . * String[String.length] doesn't trap.
71 . * Rhythmic_column and interaction stem/rhythmic_column/note_head/dots.
75 . * Lookup::text -> needs to be TeX independent.
76 . * junk Music_iterator::first_b_
80 . * [c8. c16 c16 c16] in 6/8 timesig.
81 . * staffside spanner (crescendo!) along with staffswitch.
82 . * --- 2, margin notes don't work correctly for the pianostaff (in the
83 following example, i expect the "piano" string to be centered
84 vertically between the two staves):
87 \notes \context PianoStaff <
88 \property PianoStaff.instrument = "Piano"
89 \context Staff = treble {
92 \context Staff = bass {
98 \translator { \StaffContext \consists "Staff_margin_engraver"; }
99 \translator { \PianoStaffContext \consists "Staff_margin_engraver"; }
107 . * sort out breve shapes.
108 . * \time forces keysig?
111 . * We need feta-din*.mf files for more sizes than 10.
113 - The syntax for chords looks clumsy with two different meanings of
114 '-' and different syntax for separating modifiers from the tonic
115 and from other modifiers. Why not use for example ':' between
116 tonic and modifier and between the different modifiers?
118 - Rests and beams don't work too well together. Example:
119 [ r8 g''16 des'] [r8 c16 a]
121 - The stemLength property should affect also beamed stems.
123 . * align left edge of broken tuplet-spanner (have a test case?)
124 . * fix dynamics decently, ie. use kerning & ligatures.
125 . * key restorations & repeats
126 . * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
127 . * * auto melismaBusy for beams.
128 . *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
129 ends on a pair of grace notes. Standard practice is to mark this with
130 a slur starting on the main note and ending on the grace note, so a
131 singer knows where to break the words.
133 In bar 27, there's a crescendo that's supposed to start at the start
134 of the grace notes and extend to the note after the grace notes.
135 . * 5. Sometimes lyrics extend past the right end of the staff. I guess that
136 this is a similar problem (if not another symptom of the same problem) as
137 one of the spacing bugs mentioned in the TODO.
138 . * 4. Lyrics and grace sections don't go too well together.
139 The words are aligned with the main note, not the start of the
140 grace note. This is usually wrong, but is sometimes right.
141 . * decimal point in \paper {}
143 . * repeats and partial measures.
144 . * rhythmic staff & accidentals.
145 . * use melismaBusy in Lyric context to typeset melismata correctly.
146 . * ly2dvi/lilypond logfile.
147 . * hang Item on Spanner
148 . * do --safe for PS output?
150 . * collision of lyrics with span_bars. See star-spangled.
151 . * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
152 . * It is impossible to typeset two textual scripts that are stacked
153 on top of eachother and avoids note collisions and at the same
154 time are typeset with different textStyle. I tried to move around
155 the text_engraver and other engravers between Voice and Thread
156 but the granularity is not fine enough, the scripts have to
157 share the same engraver in order to be get correct vertical
158 position but than they cannot have different style.
159 In my opinion, all scripts that share the same staff, should
160 be stacked vertically, avoiding collisions with the notes
163 . * break priority setting from SCM.
165 . * don't shorten stems/staffs closer to each other.
166 . * accidentals closer to note head
167 . * to space the staffs/staffgroups contained in the score.
170 . * tuplets that are written as "number : note", for example
171 "3 : [image of a half note here]". possible?
172 . * a note with a circle after it, meaning:
174 note + circle = note + 1/4 of its length
176 the circle is like a dot that's not filled in. for example, on
177 page three, the c-sharp on the second line should be a quarter with
178 a circle, not a quarter tied to a sixteenth. is this at all
180 . * scm-ify \property values.
181 . * make dependencies () a virtual function.
182 . * deprecate hangOnClef.
183 . * Abstraction for engravers:
184 . * make "in-between" engraver (Tie)
185 . * make wide_spanner_engraver (line_group_spanner, staff_symbol)
186 . * store req -> element, element -> element causes for warnings
187 . * compulsory hshift
188 . * My wish list for lyrics. I dream of a time when I will have enough time to
189 become familiar enough with the source code to be able to implement some of
190 these myself, but I don't know when that will be, so I thought I'd "publish"
191 my suggestions in case someone else is in a position to give them some
192 priority. Otherwise, perhaps they could go on the todo list?
194 If any of these are already implemented, please let me what the syntax is to
197 1. Stanza numbering. Numbering at the beginning of a song with the number
198 set to the left of the first note. It would also be nice (but not as
199 important) to be able to have some form of automatic numbering at the
200 beginning of each new line. This would make it easier to follow songs with a
201 large number of stanzas.
203 3. Notes centred above/below lyrics rather than left-aligned.
205 4. It would be very nice to be able to build some kind of phrasing into the
206 lyrics of hymns, etc, so that the first words of a phrase are left aligned
207 with each other, the last words are right aligned, and the words in between
210 5. In a song, with (say) four stanzas and a chorus, it would be nice to be
211 able to vertically align the chorus midway between the staves.
213 6. It would be nice to be able to put vertical brackets either side of a
214 repeated section with different words for each repeat.
215 . * Give # lines in linebreaking.
217 . * rewrite context defs using Scheme
218 . * junk TeX specifics from internal code.
219 . * \selectmusic to cut pieces from music.
220 . * formatting of input stuff.
222 . * TODO: merge atom & molecule; make tree from molecule.
223 . * Align_element::padding ?
224 . * typo checks on property names?
225 . * use streambufs and iostream
226 to provide IO handling for TeX stream, mudela stream, data-file.
227 . * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
228 . * strip EXEs before installing
229 . * zip target for binary windows dist (JBR)
230 . * fix partial measures in meaningful way.
231 . * uniformise recent feta contributions.
232 . * bigger and fatter 4/4 C

250 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
251 {\voicetwo cis,4 r r | r2. | r1 }> |
253 . * Musical_pitch (analogous to Duration and Rhythmic_req)
254 think about, analogous to pitch:
255 * { a4 a16 } c <-- duration of c?
256 * < a4 b8 > c <-- duration of c?
258 . * make sure all ex's have a mudela-version
259 . * do rest-collisions for Multi_measure_rests as well.
260 . * split error/warning in error/warning/non_fatal_error
261 . * add a Duration_convert member to Duration_iter to set parameters.
262 Junk global duration settings.
263 . * en-,discouraged linebreaking:
264 . * handle DISALLOW < penalty > FORCE
265 . * discourage breaking of slurs
266 . * fix variable define/lookup parser global<->paper
267 . * fix title/instrument placements; see input/test/title.ly
268 . * <\voiceone c4. \voicetwo c4>
269 . * I'd like to change the \repetitions command to Jan's suggested
270 syntax: \repeat "repeatsymbol" 2 {...}, but I'm not sure that
271 I understand the implementation of repeats well enough.
272 . * add full cello suites to web site (kom op, Maarten!)
273 . * rename 'staff_line_leading' (who is being lead where?) to
274 staff_space, interline; (or other meaningful name) and use throughout
277 [-> leading are the lead strips between the sticks (lines) of
278 typeface. ie. leading is vertical space --hwn]
279 . * add mudela-book-doc source to webstie.

291 . * make LilyPond RPM fully relocatable
292 . * better hshift (dots, distance, head dependent)
293 . * didot / big point.
294 . * clefs (AG): The "8" should appear closer to the actual clef,
296 . * put errorlevel in Input class

298 . * distinguish between unset and empty properties.
301 . * the bracket is ugly (wings are too parabolic, should be more circular)

395 . * output header info to MIDI too.
397 . * a musical dictionary. See Documentation/vocabulary-*, other
407 . * guitar chords (fret diagrams)

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

511 . * merge key{item} & localkey{item}?
512 . * spacing, national styles?
