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 . * align left edge of broken (de)cresc/slur/tie/tuplet/volta
13 . * auto-staff-switching.
14 . * warning if feta-nummer.tfm not found
16 input/star-spangled-banner.ly: hw?
17 mutopia/J.S.Bach/Solo-Cello-Suites/prelude-cello.ly: hw: slurs + autobeamer ?
19 . * spacing of accidentals
20 . * key restorations & repeats
21 . * spanners from grace to normal ctxt
23 . * Grace_slur_engraver.
24 . * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
25 . * input/star-spangled-banner.ly: fold for lyrics?
26 . * Break_req handling is silly (break_forbid () + \break fucks up.)
27 . * account for accidentals in spacing.
28 . * \shape 1st dim skipped?
29 . * We need feta-din*.mf files for more sizes than 10.
30 . * fix dynamics decently, ie. use kerning & ligatures.
33 . * \$ and $ identifier syntax in examples.
34 . * Junk ghost positioning objects eg, Script leans on Staffside
38 . * Key_engraver, Local_key_item
39 . * Think of comprehensive solution for "if (grace_b == self_grace_b_)"
40 . * Y dimension units: staffspace vs. Point
43 . * Rhythmic_column and interaction stem/rhythmic_column/note_head/dots.
47 . * Lookup::text -> needs to be TeX independent.
48 . * junk Music_iterator::first_b_
52 . * [c8. c16 c16 c16] in 6/8 timesig.
55 > {\voiceone c''4. r8}
60 . *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
61 ends on a pair of grace notes. Standard practice is to mark this with
62 a slur starting on the main note and ending on the grace note, so a
63 singer knows where to break the words.
65 In bar 27, there's a crescendo that's supposed to start at the start
66 of the grace notes and extend to the note after the grace notes.
67 . * 5. Sometimes lyrics extend past the right end of the staff. I guess that
68 this is a similar problem (if not another symptom of the same problem) as
69 one of the spacing bugs mentioned in the TODO.
70 . * 4. Lyrics and grace sections don't go too well together.
71 The words are aligned with the main note, not the start of the
72 grace note. This is usually wrong, but is sometimes right.
73 . * decimal point in \paper {}
75 . * use melismaBusy in Lyric context to typeset melismata correctly.
76 . * ly2dvi/lilypond logfile.
77 . * hang Item on Spanner
78 . * do --safe for PS output?
80 . * collision of lyrics with span_bars. See star-spangled.
81 . * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
82 . * It is impossible to typeset two textual scripts that are stacked
83 on top of eachother and avoids note collisions and at the same
84 time are typeset with different textStyle. I tried to move around
85 the text_engraver and other engravers between Voice and Thread
86 but the granularity is not fine enough, the scripts have to
87 share the same engraver in order to be get correct vertical
88 position but than they cannot have different style.
89 In my opinion, all scripts that share the same staff, should
90 be stacked vertically, avoiding collisions with the notes
93 . * break priority setting from SCM.
95 . * don't shorten stems/staffs closer to each other.
96 . * accidentals closer to note head
97 . * to space the staffs/staffgroups contained in the score.
100 . * tuplets that are written as "number : note", for example
101 "3 : [image of a half note here]". possible?
102 . * a note with a circle after it, meaning:
104 note + circle = note + 1/4 of its length
106 the circle is like a dot that's not filled in. for example, on
107 page three, the c-sharp on the second line should be a quarter with
108 a circle, not a quarter tied to a sixteenth. is this at all
110 . * scm-ify \property values.
111 . * make dependencies () a virtual function.
112 . * deprecate hangOnClef.
113 . * Abstraction for engravers:
114 . * make "in-between" engraver (Tie)
115 . * make wide_spanner_engraver (line_group_spanner, staff_symbol)
116 . * store req -> element, element -> element causes for warnings
117 . * compulsory hshift
118 . * My wish list for lyrics. I dream of a time when I will have enough time to
119 become familiar enough with the source code to be able to implement some of
120 these myself, but I don't know when that will be, so I thought I'd "publish"
121 my suggestions in case someone else is in a position to give them some
122 priority. Otherwise, perhaps they could go on the todo list?
124 If any of these are already implemented, please let me what the syntax is to
127 1. Stanza numbering. Numbering at the beginning of a song with the number
128 set to the left of the first note. It would also be nice (but not as
129 important) to be able to have some form of automatic numbering at the
130 beginning of each new line. This would make it easier to follow songs with a
131 large number of stanzas.
133 3. Notes centred above/below lyrics rather than left-aligned.
135 4. It would be very nice to be able to build some kind of phrasing into the
136 lyrics of hymns, etc, so that the first words of a phrase are left aligned
137 with each other, the last words are right aligned, and the words in between
140 5. In a song, with (say) four stanzas and a chorus, it would be nice to be
141 able to vertically align the chorus midway between the staves.
143 6. It would be nice to be able to put vertical brackets either side of a
144 repeated section with different words for each repeat.
146 . * Give # lines in linebreaking.
148 . * rewrite context defs using Scheme
149 . * junk TeX specifics from internal code.
150 . * \selectmusic to cut pieces from music.
151 . * formatting of input stuff.
153 . * TODO: merge atom & molecule; make tree from molecule.
154 . * Align_element::padding ?
155 . * typo checks on property names?
156 . * use streambufs and iostream
157 to provide IO handling for TeX stream, mudela stream, data-file.
158 . * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
159 . * strip EXEs before installing
160 . * zip target for binary windows dist (JBR)
161 . * fix partial measures in meaningful way.
162 . * uniformise recent feta contributions.
163 . * bigger and fatter 4/4 C
164 . * relative mode for midi2ly
165 . * junking \skip req in lyrics
166 . * midi2ly empty staffs.
167 . * use Fourier transformation for rhythmic quantisation.
168 . * horizontal centering of dynamics
169 . * $DEPENDENCIES_OUTPUT support
170 . * turn slope-damping on/off

182 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
183 {\voicetwo cis,4 r r | r2. | r1 }> |
185 . * Musical_pitch (analogous to Duration and Rhythmic_req)
186 think about, analogous to pitch:
187 * { a4 a16 } c <-- duration of c?
188 * < a4 b8 > c <-- duration of c?
190 . * make sure all ex's have a mudela-version
191 . * do rest-collisions for Multi_measure_rests as well.
192 . * split error/warning in error/warning/non_fatal_error
193 . * add a Duration_convert member to Duration_iter to set parameters.
194 Junk global duration settings.
195 . * en-,discouraged linebreaking:
196 . * handle DISALLOW < penalty > FORCE
197 . * discourage breaking of slurs
198 . * fix variable define/lookup parser global<->paper
199 . * fix title/instrument placements; see input/test/title.ly
200 . * <\voiceone c4. \voicetwo c4>
201 . * I'd like to change the \repetitions command to Jan's suggested
202 syntax: \repeat "repeatsymbol" 2 {...}, but I'm not sure that
203 I understand the implementation of repeats well enough.
204 . * add full cello suites to web site (kom op, Maarten!)
205 . * rename 'staff_line_leading' (who is being lead where?) to
206 staff_space, interline; (or other meaningful name) and use throughout
209 [-> leading are the lead strips between the sticks (lines) of
210 typeface. ie. leading is vertical space --hwn]
211 . * add mudela-book-doc source to webstie.

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

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

236 . * rewrite dynamic signs. They're kind of spaghetti now.
237 . * The `3' in the meter key is a one or two pixels too thin (at 600dpi)

330 . * output header info to MIDI too.

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