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 . * Break_req handling is silly (break_forbid () + \break fucks up.)
13 . * chord names. -- what about?
14 . * Melismas(*) --> Melismata (at least in doco)
15 . * ? -Q, --find-old-relative show all changes in relative syntax
16 What's old about absolute to relative conversion? Could maybe use for
20 . * \$ and $ identifier syntax in examples.
21 . * Junk ghost positioning objects eg, Script leans on Staffside
25 . * Key_engraver, Local_key_item
26 . * Think of comprehensive solution for "if (grace_b == self_grace_b_)"
27 . * String[String.length] doesn't trap.
28 . * y dimension units: staffspace vs. Point
31 . * Rhythmic_column and interaction stem/rhythmic_column/note_head/dots.
35 . * Lookup::text -> needs to be TeX independent.
36 . * junk Music_iterator::first_b_
40 . * [c8. c16 c16 c16] in 6/8 timesig.
41 . * staffside spanner (crescendo!) along with staffswitch.
49 . * We need feta-din*.mf files for more sizes than 10.
50 . * align left edge of broken (de)cresc/slur/tie/tuplet/volta
51 . * fix dynamics decently, ie. use kerning & ligatures.
52 . * key restorations & repeats
53 . * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
54 . * * auto melismaBusy for beams.
55 . *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
56 ends on a pair of grace notes. Standard practice is to mark this with
57 a slur starting on the main note and ending on the grace note, so a
58 singer knows where to break the words.
60 In bar 27, there's a crescendo that's supposed to start at the start
61 of the grace notes and extend to the note after the grace notes.
62 . * 5. Sometimes lyrics extend past the right end of the staff. I guess that
63 this is a similar problem (if not another symptom of the same problem) as
64 one of the spacing bugs mentioned in the TODO.
65 . * 4. Lyrics and grace sections don't go too well together.
66 The words are aligned with the main note, not the start of the
67 grace note. This is usually wrong, but is sometimes right.
68 . * decimal point in \paper {}
70 . * repeats and partial measures.
71 . * rhythmic staff & accidentals.
72 . * use melismaBusy in Lyric context to typeset melismata correctly.
73 . * ly2dvi/lilypond logfile.
75 . * hang Item on Spanner
76 . * do --safe for PS output?
78 . * collision of lyrics with span_bars. See star-spangled.
79 . * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
80 . * It is impossible to typeset two textual scripts that are stacked
81 on top of eachother and avoids note collisions and at the same
82 time are typeset with different textStyle. I tried to move around
83 the text_engraver and other engravers between Voice and Thread
84 but the granularity is not fine enough, the scripts have to
85 share the same engraver in order to be get correct vertical
86 position but than they cannot have different style.
87 In my opinion, all scripts that share the same staff, should
88 be stacked vertically, avoiding collisions with the notes
91 . * break priority setting from SCM.
93 . * don't shorten stems/staffs closer to each other.
94 . * accidentals closer to note head
95 . * to space the staffs/staffgroups contained in the score.
98 . * tuplets that are written as "number : note", for example
99 "3 : [image of a half note here]". possible?
100 . * a note with a circle after it, meaning:
102 note + circle = note + 1/4 of its length
104 the circle is like a dot that's not filled in. for example, on
105 page three, the c-sharp on the second line should be a quarter with
106 a circle, not a quarter tied to a sixteenth. is this at all
108 . * scm-ify \property values.
109 . * make dependencies () a virtual function.
110 . * deprecate hangOnClef.
111 . * Abstraction for engravers:
112 . * make "in-between" engraver (Tie)
113 . * make wide_spanner_engraver (line_group_spanner, staff_symbol)
114 . * store req -> element, element -> element causes for warnings
115 . * compulsory hshift
116 . * My wish list for lyrics. I dream of a time when I will have enough time to
117 become familiar enough with the source code to be able to implement some of
118 these myself, but I don't know when that will be, so I thought I'd "publish"
119 my suggestions in case someone else is in a position to give them some
120 priority. Otherwise, perhaps they could go on the todo list?
122 If any of these are already implemented, please let me what the syntax is to
125 1. Stanza numbering. Numbering at the beginning of a song with the number
126 set to the left of the first note. It would also be nice (but not as
127 important) to be able to have some form of automatic numbering at the
128 beginning of each new line. This would make it easier to follow songs with a
129 large number of stanzas.
131 3. Notes centred above/below lyrics rather than left-aligned.
133 4. It would be very nice to be able to build some kind of phrasing into the
134 lyrics of hymns, etc, so that the first words of a phrase are left aligned
135 with each other, the last words are right aligned, and the words in between
138 5. In a song, with (say) four stanzas and a chorus, it would be nice to be
139 able to vertically align the chorus midway between the staves.
141 6. It would be nice to be able to put vertical brackets either side of a
142 repeated section with different words for each repeat.
144 . * Give # lines in linebreaking.
146 . * rewrite context defs using Scheme
147 . * junk TeX specifics from internal code.
148 . * \selectmusic to cut pieces from music.
149 . * formatting of input stuff.
151 . * TODO: merge atom & molecule; make tree from molecule.
152 . * Align_element::padding ?
153 . * typo checks on property names?
154 . * use streambufs and iostream
155 to provide IO handling for TeX stream, mudela stream, data-file.
156 . * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
157 . * strip EXEs before installing
158 . * zip target for binary windows dist (JBR)
159 . * fix partial measures in meaningful way.
160 . * uniformise recent feta contributions.
161 . * bigger and fatter 4/4 C
162 . * relative mode for midi2ly

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

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

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

325 . * output header info to MIDI too.
327 . * a musical dictionary. See Documentation/vocabulary-*, other
337 . * guitar chords (fret diagrams)
338 . * other chord name styles (american(?) style)

344 . * indentable stream as baseclass for TeX stream, lily stream, Dstream.
345 . * use dstream feature in midi2ly
346 . * integrate IO checking into stream class
353 . * add to MIDI output:
354 . * sharp / flat on trills (in MIDI ??)
355 . * ornaments (and trills?)
359 > Would it be hard to add support for proper dynamics in MIDI output? I
360 > would really like to have this feature...
362 Concretely spoken, for dynamics you have to write a performer
363 (Dynamics_performer), that will take the input requests. If I
364 understand correctly, every MIDI note played must have its dynamic
365 strength set separately. That means the the Dynamics_performer must
366 set the strength of every Audio_note it finds. This means that one
367 has to modify existing Audio items. The best way of doing this is
368 with a broadcast/acknowledge process.
370 So the best way of handling this, is
372 1 supporting dynamic settings in Audio_note
374 2 Write a Dynamics_performer that will modify
375 any notes it finds to set appropriate strengths.
377 I'd say that the work involved is not hard, but you have to be fluent
378 with C++ and need some insight into the working of Notation Contexts
379 and friends. I guess I could do it in a day or so, but if you are not
380 so fluent with the inner workings of LilyPond, it could take you some
381 more time (A few more days?).
383 Please note, that I am *not* going to code this myself: my days are
384 valuable, and I think I have more interesting things to do than fixing
385 the MIDI output (I don't even have a soundcard). But I *do* want to help
386 you or other people with implementing this, so if you need help, don't
