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
13 . * Break_req handling is silly (break_forbid () + \break fucks up.)
16 . * HaraKiriStaffContext removes bar lines and doesn't remove
17 staff margin text on removed staff lines.
20 - I would like the possibility of forcing clef- and key- changes to be
21 printed _after_ the new bar line
23 - I would like an option to define the number of systems on which the
24 score must be distributed. As it is now it seems that I may only
25 influence that indirectly through the gourlay_maxmeasures property.
27 - if I change the property minVerticalAlign in a multi staff score with
28 lyrics the change affects the lyrics too. I would like the change to
31 - I would like to be able to influence the sloping of xtuplet brackets
33 - for one of my test scores containing a modern edition of an early
34 17'th century composition I have a leading measure containing the
35 orginal clefs and note values of the original composition. I use the
36 "harmonic" and "diamond" note head styles for that measure and would
37 like to have the stems of these notes _centered_ on the notehead as in
38 the mensural music notation.
40 - after the leading measure in the above mentioned score I want a double
41 bar line fully drawn across the staves and after that keep to the
42 ChoirStaff bar line types in the rest of the scores
44 . * autoBeamMelisma: if I explicitly beam notes in a staff with auto beaming disabled I
45 would like to have these beams also to be melismatic.
47 . * make all Feta (including dynamics) available to the user in
48 textual scripts. Examples: "D.S. al \coda", "\mf espress.".
50 . * ? -Q, --find-old-relative show all changes in relative syntax
51 What's old about absolute to relative conversion? Could maybe use for
55 . * \$ and $ identifier syntax in examples.
56 . * Junk ghost positioning objects eg, Script leans on Staffside
60 . * center option (??)
61 . * make mudela-book understand usepackage{geometry}
62 . * check that linewidth set in \paper is not wider than actual linewidth?
63 . * the following fails because mudelabook doesn't care that the
64 last } after \end{mudela} finishes the marginpar:
69 . * force-verbatim is maybe not that useful since latex fails with footnotes,
72 . * Key_engraver, Local_key_item
73 . * Think of comprehensive solution for "if (grace_b == self_grace_b_)"
74 . * String[String.length] doesn't trap.
77 . * Rhythmic_column and interaction stem/rhythmic_column/note_head/dots.
81 . * Lookup::text -> needs to be TeX independent.
82 . * junk Music_iterator::first_b_
86 . * [c8. c16 c16 c16] in 6/8 timesig.
87 . * staffside spanner (crescendo!) along with staffswitch.
88 . * --- 2, margin notes don't work correctly for the pianostaff (in the
89 following example, i expect the "piano" string to be centered
90 vertically between the two staves):
93 \notes \context PianoStaff <
94 \property PianoStaff.instrument = "Piano"
95 \context Staff = treble {
98 \context Staff = bass {
104 \translator { \StaffContext \consists "Staff_margin_engraver"; }
105 \translator { \PianoStaffContext \consists "Staff_margin_engraver"; }
113 . * sort out breve shapes.
114 . * \time forces keysig?
117 . * We need feta-din*.mf files for more sizes than 10.
119 - The syntax for chords looks clumsy with two different meanings of
120 '-' and different syntax for separating modifiers from the tonic
121 and from other modifiers. Why not use for example ':' between
122 tonic and modifier and between the different modifiers?
124 - Rests and beams don't work too well together. Example:
125 [ r8 g''16 des'] [r8 c16 a]
127 - The stemLength property should affect also beamed stems.
129 . * align left edge of broken (de)cresc/slur/tie/tuplet/volta
130 . * fix dynamics decently, ie. use kerning & ligatures.
131 . * key restorations & repeats
132 . * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
133 . * * auto melismaBusy for beams.
134 . *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
135 ends on a pair of grace notes. Standard practice is to mark this with
136 a slur starting on the main note and ending on the grace note, so a
137 singer knows where to break the words.
139 In bar 27, there's a crescendo that's supposed to start at the start
140 of the grace notes and extend to the note after the grace notes.
141 . * 5. Sometimes lyrics extend past the right end of the staff. I guess that
142 this is a similar problem (if not another symptom of the same problem) as
143 one of the spacing bugs mentioned in the TODO.
144 . * 4. Lyrics and grace sections don't go too well together.
145 The words are aligned with the main note, not the start of the
146 grace note. This is usually wrong, but is sometimes right.
147 . * decimal point in \paper {}
149 . * repeats and partial measures.
150 . * rhythmic staff & accidentals.
151 . * use melismaBusy in Lyric context to typeset melismata correctly.
152 . * ly2dvi/lilypond logfile.
154 . * hang Item on Spanner
155 . * do --safe for PS output?
157 . * collision of lyrics with span_bars. See star-spangled.
158 . * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
159 . * It is impossible to typeset two textual scripts that are stacked
160 on top of eachother and avoids note collisions and at the same
161 time are typeset with different textStyle. I tried to move around
162 the text_engraver and other engravers between Voice and Thread
163 but the granularity is not fine enough, the scripts have to
164 share the same engraver in order to be get correct vertical
165 position but than they cannot have different style.
166 In my opinion, all scripts that share the same staff, should
167 be stacked vertically, avoiding collisions with the notes
170 . * break priority setting from SCM.
172 . * don't shorten stems/staffs closer to each other.
173 . * accidentals closer to note head
174 . * to space the staffs/staffgroups contained in the score.
177 . * tuplets that are written as "number : note", for example
178 "3 : [image of a half note here]". possible?
179 . * a note with a circle after it, meaning:
181 note + circle = note + 1/4 of its length
183 the circle is like a dot that's not filled in. for example, on
184 page three, the c-sharp on the second line should be a quarter with
185 a circle, not a quarter tied to a sixteenth. is this at all
187 . * scm-ify \property values.
188 . * make dependencies () a virtual function.
189 . * deprecate hangOnClef.
190 . * Abstraction for engravers:
191 . * make "in-between" engraver (Tie)
192 . * make wide_spanner_engraver (line_group_spanner, staff_symbol)
193 . * store req -> element, element -> element causes for warnings
194 . * compulsory hshift
195 . * My wish list for lyrics. I dream of a time when I will have enough time to
196 become familiar enough with the source code to be able to implement some of
197 these myself, but I don't know when that will be, so I thought I'd "publish"
198 my suggestions in case someone else is in a position to give them some
199 priority. Otherwise, perhaps they could go on the todo list?
201 If any of these are already implemented, please let me what the syntax is to
204 1. Stanza numbering. Numbering at the beginning of a song with the number
205 set to the left of the first note. It would also be nice (but not as
206 important) to be able to have some form of automatic numbering at the
207 beginning of each new line. This would make it easier to follow songs with a
208 large number of stanzas.
210 3. Notes centred above/below lyrics rather than left-aligned.
212 4. It would be very nice to be able to build some kind of phrasing into the
213 lyrics of hymns, etc, so that the first words of a phrase are left aligned
214 with each other, the last words are right aligned, and the words in between
217 5. In a song, with (say) four stanzas and a chorus, it would be nice to be
218 able to vertically align the chorus midway between the staves.
220 6. It would be nice to be able to put vertical brackets either side of a
221 repeated section with different words for each repeat.
223 . * Give # lines in linebreaking.
225 . * rewrite context defs using Scheme
226 . * junk TeX specifics from internal code.
227 . * \selectmusic to cut pieces from music.
228 . * formatting of input stuff.
230 . * TODO: merge atom & molecule; make tree from molecule.
231 . * Align_element::padding ?
232 . * typo checks on property names?
233 . * use streambufs and iostream
234 to provide IO handling for TeX stream, mudela stream, data-file.
235 . * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
236 . * strip EXEs before installing
237 . * zip target for binary windows dist (JBR)
238 . * fix partial measures in meaningful way.
239 . * uniformise recent feta contributions.

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

300 . * make LilyPond RPM fully relocatable
301 . * better hshift (dots, distance, head dependent)
302 . * didot / big point.
303 . * clefs (AG): The "8" should appear closer to the actual clef,

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

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

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