1 Features you cannot find in the doco as working, should be mentioned here.
4 This is an assorted collection of stuff that will be done, might be
5 done, or is an idea that I want to think about
7 Most of the items are marked in the code as well, with full explanation.
8 grep for TODO and ugh/ugr/urg
12 * disallow backslashes
14 * \breathmark TeX macro
18 * add new glyphs to font.ly
20 * formatting of input stuff.
22 * \notes{ a \< b \cr } vs \notes{ a \< b \! }
24 * if possible, it might be nice for a warning to appear if someone does
25 \translator with no name and without assigning it to an
32 * fix singleStaffBracket
34 * repeat bars: need distance after ":|" and before "|:"
36 * The time signature warnings still remain, will be fixed later.

43 * repeat bars: need distance after ":|" and before "|:"
45 * \shape 1st dim skipped?
47 * fix marks/barnumbers/marginal notes
50 lbheel = \script { "bheel" 0 0 -1 0 0 }
51 rbheel = \script { "bheel" 0 0 1 0 0 }
52 lbtoe = \script { "btoe" 0 0 -1 0 0 }
53 rbtoe = \script { "btoe" 0 0 1 0 0 }
54 lfheel = \script { "fheel" 0 0 -1 0 0 }
55 rfheel = \script { "fheel" 0 0 1 0 0 }
56 lftoe = \script { "ftoe" 0 0 -1 0 0 }
57 rftoe = \script { "ftoe" 0 0 1 0 0 }
61 portato= \script { "portato" 0 -1 0 1 0 }
63 * Align_element::padding ?
65 * uniformise property names.
67 * ydirection <-> yDirection
69 * typo checks on property names?
71 * make engraver hacking robust.
73 * use streambufs and iostream
74 to provide IO handling for TeX stream, mudela stream, data-file.
76 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
78 * strip EXEs before installing
80 * zip target for binary windows dist (JBR)
84 * revise documentation
88 * junking \skip req in lyrics
95 - mix engraver hacking with music ?
96 - \once\property KEY = VAL

132 gs: Error: /undefined in draw_beam
135 * run texhash after installing .tex
137 * fix vertical alignment and stafflines
139 * GrandStaff needs more work -- I want a single word
140 `harpsichord' to the left of the grandstaff, not one on each
141 stave. (Organ staff -- with separate pedal -- but common
142 properties may be something to think about. Of course for
143 organ you want to be able to give stop indications on the way
144 through, so the \property Voice.Instrument would be a stop,
145 and \property GrandStaff.instrument would be PipeOrgan...)
147 * make Tie_req a "command" { <c g> ~ <c g> }
151 * revise the Score_priority_align_engraver concept. It sucks.

171 * try to use template<Type> iso MACRO(Type)
173 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
174 think about, analogous to pitch:
175 * { a4 a16 } c <-- duration of c?
176 * <a4 b8> c <-- duration of c?
180 * fix audio-items (don't use (input) requests, but copy data)
182 * junk My_lily_parser::abbrev_beam_type_i_

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

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

356 * use properties for:
361 - bartypes (get rid of derived Span_bar_engravers)
366 - optimal pagebreaking.
368 * Unicode support? -> man 7 unicode
371 - detect of 16/8 bit files
372 - examples to go with it.

455 - Move all Score_elems, into libmutype.a
459 - Doc (C) stuff of sheet music
460 - a better format? SGML? TeX? Info?
463 * more spanners (smallish)
467 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
469 - doc on Rhythmic_grouping
470 - general shaving on Beam and Stem
472 - separate visual from rhythmic info even more
474 - endbeam req should be *after* the duration, so you can do
480 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
481 - set different line sizes / thicknesses
482 - beam stem showthrough, inter beam sizes (french vs german style)
485 - left/right note balls should be handled by Collision:

489 - merge key{item} & localkey{item}?
491 - spacing, national styles?
494 - redo Notehead to allow digits as heads

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