1 Features you cannot find in the doco as working, should be mentioned here.
3 This is an assorted collection of stuff that will be done, might be
4 done, or is an idea that I want to think about
6 Most of the items are marked in the code as well, with full explanation.
7 grep for TODO and ugh/ugr/urg
13 * latex bla.tex broken (titles / \lilyfooter stuff?)
15 * acc placement: \score { \notes \key G; \transpose\notes { a b c } }

21 * \breathmark TeX macro
23 * configure error if GUILE 1.3 not found
27 * add new glyphs to font.ly
29 * formatting of input stuff.
31 * \notes{ a \< b \cr } vs \notes{ a \< b \! }
33 * if possible, it might be nice for a warning to appear if someone does
34 \translator with no name and without assigning it to an
41 * fix singleStaffBracket
43 * repeat bars: need distance after ":|" and before "|:"
45 * The time signature warnings still remain, will be fixed later.
47 Summary of minor spelling irregularities:
48 - capitalization/use of underscores in property names
52 * repeat bars: need distance after ":|" and before "|:"
54 * \shape 1st dim skipped?
56 * fix marks/barnumbers/marginal notes

61 lbtoe = \script { "btoe" 0 0 -1 0 0 }
62 rbtoe = \script { "btoe" 0 0 1 0 0 }
63 lfheel = \script { "fheel" 0 0 -1 0 0 }
64 rfheel = \script { "fheel" 0 0 1 0 0 }
65 lftoe = \script { "ftoe" 0 0 -1 0 0 }
66 rftoe = \script { "ftoe" 0 0 1 0 0 }
70 portato= \script { "portato" 0 -1 0 1 0 }
72 * Align_element::padding ?
74 * uniformise property names.
76 * ydirection <-> yDirection
78 * typo checks on property names?
80 * make engraver hacking robust.
82 * use streambufs and iostream
83 to provide IO handling for TeX stream, mudela stream, data-file.
85 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
87 * strip EXEs before installing
89 * zip target for binary windows dist (JBR)
93 * revise documentation
97 * junking \skip req in lyrics
100 - \type -> \context ?
104 - mix engraver hacking with music ?
105 - \once\property KEY = VAL
106 - \addtranslator, \removetranslator

140 * Xdvi zooming ?! Try to understand GS garbage collection.
141 gs: Error: /undefined in draw_beam
144 * run texhash after installing .tex
146 * fix vertical alignment and stafflines
148 * GrandStaff needs more work -- I want a single word
149 `harpsichord' to the left of the grandstaff, not one on each
150 stave. (Organ staff -- with separate pedal -- but common
151 properties may be something to think about. Of course for
152 organ you want to be able to give stop indications on the way
153 through, so the \property Voice.Instrument would be a stop,
154 and \property GrandStaff.instrument would be PipeOrgan...)
156 * make Tie_req a "command" { <c g> ~ <c g> }

180 * try to use template<Type> iso MACRO(Type)
182 - NEWS: ... 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?
189 * fix audio-items (don't use (input) requests, but copy data)
191 * junk My_lily_parser::abbrev_beam_type_i_
193 * make sure all ex's have a mudela-version

248 * disable spaces in TeX stuff
250 * handle ^C for tmp/file creation.
252 * dots & rest collisions.
260 * versioning for Feta
262 * the warning about the negative slur/tie length appears twice
265 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
268 * the bracket is ugly (wings are too parabolic, should be more circular)
270 * better hshift (dots, distance, head dependent)
272 * clefs (AG): The "8" should appear closer to the actual clef,
275 * put errorlevel in Input class
279 * integrate midi-elts from mi2mu and lily?
282 FMR: Free memory read:
283 * This is occurring while in:

310 Postprocessing elements...
311 TeX output to score-bar-scripts.tex...
316 * redhat (v?) graphical install bomb-out?
318 * GNU diff 2.7: diff -rN does not see a new directory with empty file
320 * GNU patch 2.1: <must find simple example> if patch chokes on a
321 hunk, or on allegedly unsorted hunks in a diff, it may stop
322 without a trace of failure (create .rej file, print error or
323 dump core) and just ignore any further diffs.
327 f = fopen ("/dev/null", "r")
332 * GNU indent: handle C++

363 * use properties for:
368 - bartypes (get rid of derived Span_bar_engravers)
373 - optimal pagebreaking.
375 * Unicode support? -> man 7 unicode
378 - detect of 16/8 bit files
379 - examples to go with it.

461 - PostScript output (esp. Beams, Slurs, etc)
462 - Move all Score_elems, into libmutype.a
466 - Doc (C) stuff of sheet music
467 - a better format? SGML? TeX? Info?
470 * more spanners (smallish)
474 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
476 - doc on Rhythmic_grouping
477 - general shaving on Beam and Stem
479 - separate visual from rhythmic info even more
481 - endbeam req should be *after* the duration, so you can do
487 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
488 - set different line sizes / thicknesses
489 - beam stem showthrough, inter beam sizes (french vs german style)
492 - left/right note balls should be handled by Collision:
493 < \multi 2; { \stem 1; <b c> } { <f as b> } >
496 - merge key{item} & localkey{item}?
497 - spacing, national styles?
500 - redo Notehead to allow digits as heads

516 * neatly (and readably) expressing concurrent
531 * relative mode for pitch entering
535 * configure pitch_byte
537 * rest name configurable
541 * limit memory usage; the full coriolan takes up too much resources.

560 * adaptive accidental spacing.
562 * handle EOF graciously in error messages.
564 * centered whole rest
566 * declare notenametab?
568 * midi esp.: use I32 iso int where 32 bits are needed (or assumed...)
571 - A decent scalar type
