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

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

224 . * handle ^C for tmp/file creation.
225 . * make LilyPond RPM fully relocatable
226 . * better hshift (dots, distance, head dependent)
227 . * didot / big point.
228 . * clefs (AG): The "8" should appear closer to the actual clef,
230 . * put errorlevel in Input class
231 . * junk nesting slurs
232 . * distinguish between unset and empty properties.
235 . * the bracket is ugly (wings are too parabolic, should be more circular)
236 . * versioning for Feta
237 . * rewrite dynamic signs. They're kind of spaghetti now.
238 . * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
240 . * design macro for penstroke with rounded endings
241 . * timesig C: fat yet less curved. Check out relations.

331 . * output header info to MIDI too.
333 . * a musical dictionary. See Documentation/vocabulary-*, other

352 . * integrate IO checking into stream class
359 . * add to MIDI output:
360 . * sharp / flat on trills (in MIDI ??)
361 . * ornaments (and trills?)
365 > Would it be hard to add support for proper dynamics in MIDI output? I
366 > would really like to have this feature...
368 Concretely spoken, for dynamics you have to write a performer
369 (Dynamics_performer), that will take the input requests. If I
370 understand correctly, every MIDI note played must have its dynamic
371 strength set separately. That means the the Dynamics_performer must
372 set the strength of every Audio_note it finds. This means that one
373 has to modify existing Audio items. The best way of doing this is
374 with a broadcast/acknowledge process.
376 So the best way of handling this, is
378 1 supporting dynamic settings in Audio_note
380 2 Write a Dynamics_performer that will modify
381 any notes it finds to set appropriate strengths.
383 I'd say that the work involved is not hard, but you have to be fluent
384 with C++ and need some insight into the working of Notation Contexts
385 and friends. I guess I could do it in a day or so, but if you are not
386 so fluent with the inner workings of LilyPond, it could take you some
387 more time (A few more days?).
389 Please note, that I am *not* going to code this myself: my days are
390 valuable, and I think I have more interesting things to do than fixing
391 the MIDI output (I don't even have a soundcard). But I *do* want to help
392 you or other people with implementing this, so if you need help, don't
