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
13 * document new TeX/mf layout
15 * egcs-1.1 -O2 -finline-functions causes crash
17 * formatting of input stuff.
19 * use real RTTI iso access_Stuff.
21 * \notes{ a \< b \cr } vs \notes{ a \< b \! }
23 * if possible, it might be nice for a warning to appear if someone does
24 \translator with no name and without assigning it to an
31 * fix singleStaffBracket
33 * repeat bars: need distance after ":|" and before "|:"
35 * The time signature warnings still remain, will be fixed later.

42 * repeat bars: need distance after ":|" and before "|:"
44 * \shape 1st dim skipped?
46 * fix marks/barnumbers/marginal notes

51 lbtoe = \script { "btoe" 0 0 -1 0 0 }
52 rbtoe = \script { "btoe" 0 0 1 0 0 }
53 lfheel = \script { "fheel" 0 0 -1 0 0 }
54 rfheel = \script { "fheel" 0 0 1 0 0 }
55 lftoe = \script { "ftoe" 0 0 -1 0 0 }
56 rftoe = \script { "ftoe" 0 0 1 0 0 }
60 portato= \script { "portato" 0 -1 0 1 0 }
62 * Align_element::padding ?
64 * uniformise property names.
66 * ydirection <-> yDirection
68 * typo checks on property names?
70 * make engraver hacking robust.
72 * use streambufs and iostream
73 to provide IO handling for TeX stream, mudela stream, data-file.
75 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
77 * strip EXEs before installing
79 * zip target for binary windows dist (JBR)
83 * revise documentation
87 * junking \skip req in lyrics
94 - mix engraver hacking with music ?
95 - \once\property KEY = VAL

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

174 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
175 think about, analogous to pitch:
176 * { a4 a16 } c <-- duration of c?
177 * <a4 b8> c <-- duration of c?
181 * fix audio-items (don't use (input) requests, but copy data)
183 * junk My_lily_parser::abbrev_beam_type_i_

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

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

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

457 - PostScript output (esp. Beams, Slurs, etc)
458 - Move all Score_elems, into libmutype.a
462 - Doc (C) stuff of sheet music
463 - a better format? SGML? TeX? Info?
466 * more spanners (smallish)
470 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
472 - doc on Rhythmic_grouping
473 - general shaving on Beam and Stem
475 - separate visual from rhythmic info even more
477 - endbeam req should be *after* the duration, so you can do
483 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
484 - set different line sizes / thicknesses
485 - beam stem showthrough, inter beam sizes (french vs german style)

557 * adaptive accidental spacing.
559 * handle EOF graciously in error messages.
561 * centered whole rest
