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 . * check html (png) music: pictures are cut-off at the bottom over here (jcn)
15 . * Staff.noAutoBeaming = 0 ? (vs: automaticMelismas) I don't like
16 settings with negations in them (manualBeaming?)
17 . * Melismas(*) --> Melismata (at least in doco)
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.
43 > {\voiceone c''4. r8}
48 . * We need feta-din*.mf files for more sizes than 10.
49 . * align left edge of broken (de)cresc/slur/tie/tuplet/volta
50 . * fix dynamics decently, ie. use kerning & ligatures.
51 . * key restorations & repeats
52 . * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
53 . * * auto melismaBusy for beams.
54 . *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
55 ends on a pair of grace notes. Standard practice is to mark this with
56 a slur starting on the main note and ending on the grace note, so a
57 singer knows where to break the words.
59 In bar 27, there's a crescendo that's supposed to start at the start
60 of the grace notes and extend to the note after the grace notes.
61 . * 5. Sometimes lyrics extend past the right end of the staff. I guess that
62 this is a similar problem (if not another symptom of the same problem) as
63 one of the spacing bugs mentioned in the TODO.
64 . * 4. Lyrics and grace sections don't go too well together.
65 The words are aligned with the main note, not the start of the
66 grace note. This is usually wrong, but is sometimes right.
67 . * decimal point in \paper {}
69 . * repeats and partial measures.
70 . * rhythmic staff & accidentals.
71 . * use melismaBusy in Lyric context to typeset melismata correctly.
72 . * ly2dvi/lilypond logfile.
74 . * hang Item on Spanner
75 . * do --safe for PS output?
77 . * collision of lyrics with span_bars. See star-spangled.
78 . * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
79 . * It is impossible to typeset two textual scripts that are stacked
80 on top of eachother and avoids note collisions and at the same
81 time are typeset with different textStyle. I tried to move around
82 the text_engraver and other engravers between Voice and Thread
83 but the granularity is not fine enough, the scripts have to
84 share the same engraver in order to be get correct vertical
85 position but than they cannot have different style.
86 In my opinion, all scripts that share the same staff, should
87 be stacked vertically, avoiding collisions with the notes
90 . * break priority setting from SCM.
92 . * don't shorten stems/staffs closer to each other.
93 . * accidentals closer to note head
94 . * to space the staffs/staffgroups contained in the score.
97 . * tuplets that are written as "number : note", for example
98 "3 : [image of a half note here]". possible?
99 . * a note with a circle after it, meaning:
101 note + circle = note + 1/4 of its length
103 the circle is like a dot that's not filled in. for example, on
104 page three, the c-sharp on the second line should be a quarter with
105 a circle, not a quarter tied to a sixteenth. is this at all
107 . * scm-ify \property values.
108 . * make dependencies () a virtual function.
109 . * deprecate hangOnClef.
110 . * Abstraction for engravers:
111 . * make "in-between" engraver (Tie)
112 . * make wide_spanner_engraver (line_group_spanner, staff_symbol)
113 . * store req -> element, element -> element causes for warnings
114 . * compulsory hshift
115 . * My wish list for lyrics. I dream of a time when I will have enough time to
116 become familiar enough with the source code to be able to implement some of
117 these myself, but I don't know when that will be, so I thought I'd "publish"
118 my suggestions in case someone else is in a position to give them some
119 priority. Otherwise, perhaps they could go on the todo list?
121 If any of these are already implemented, please let me what the syntax is to
124 1. Stanza numbering. Numbering at the beginning of a song with the number
125 set to the left of the first note. It would also be nice (but not as
126 important) to be able to have some form of automatic numbering at the
127 beginning of each new line. This would make it easier to follow songs with a
128 large number of stanzas.
130 3. Notes centred above/below lyrics rather than left-aligned.
132 4. It would be very nice to be able to build some kind of phrasing into the
133 lyrics of hymns, etc, so that the first words of a phrase are left aligned
134 with each other, the last words are right aligned, and the words in between
137 5. In a song, with (say) four stanzas and a chorus, it would be nice to be
138 able to vertically align the chorus midway between the staves.
140 6. It would be nice to be able to put vertical brackets either side of a
141 repeated section with different words for each repeat.
143 . * Give # lines in linebreaking.
145 . * rewrite context defs using Scheme
146 . * junk TeX specifics from internal code.
147 . * \selectmusic to cut pieces from music.
148 . * formatting of input stuff.
150 . * TODO: merge atom & molecule; make tree from molecule.
151 . * Align_element::padding ?
152 . * typo checks on property names?
153 . * use streambufs and iostream
154 to provide IO handling for TeX stream, mudela stream, data-file.
155 . * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
156 . * strip EXEs before installing
157 . * zip target for binary windows dist (JBR)
158 . * fix partial measures in meaningful way.
159 . * uniformise recent feta contributions.
160 . * bigger and fatter 4/4 C
161 . * relative mode for midi2ly
162 . * junking \skip req in lyrics
163 . * midi2ly empty staffs.

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

220 . * make LilyPond RPM fully relocatable
221 . * better hshift (dots, distance, head dependent)
222 . * didot / big point.
223 . * clefs (AG): The "8" should appear closer to the actual clef,
225 . * put errorlevel in Input class
226 . * junk nesting slurs
227 . * distinguish between unset and empty properties.
230 . * the bracket is ugly (wings are too parabolic, should be more circular)
231 . * versioning for Feta
232 . * rewrite dynamic signs. They're kind of spaghetti now.
233 . * The `3' in the meter key is a one or two pixels too thin (at 600dpi)

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

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