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
14 * add new glyphs to font.ly
16 * formatting of input stuff.
18 * \notes{ a \< b \cr } vs \notes{ a \< b \! }
20 * if possible, it might be nice for a warning to appear if someone does
21 \translator with no name and without assigning it to an
28 * fix singleStaffBracket
30 * repeat bars: need distance after ":|" and before "|:"
32 * The time signature warnings still remain, will be fixed later.

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

48 lbtoe = \script { "btoe" 0 0 -1 0 0 }
49 rbtoe = \script { "btoe" 0 0 1 0 0 }
50 lfheel = \script { "fheel" 0 0 -1 0 0 }
51 rfheel = \script { "fheel" 0 0 1 0 0 }
52 lftoe = \script { "ftoe" 0 0 -1 0 0 }
53 rftoe = \script { "ftoe" 0 0 1 0 0 }

59 * Align_element::padding ?
61 * uniformise property names.
63 * ydirection <-> yDirection
65 * typo checks on property names?
67 * make engraver hacking robust.
69 * use streambufs and iostream
70 to provide IO handling for TeX stream, mudela stream, data-file.
72 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
74 * strip EXEs before installing
76 * zip target for binary windows dist (JBR)
80 * revise documentation
84 * junking \skip req in lyrics
91 - mix engraver hacking with music ?

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

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

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

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

355 * use properties for:
360 - bartypes (get rid of derived Span_bar_engravers)
365 - optimal pagebreaking.
367 * Unicode support? -> man 7 unicode
370 - detect of 16/8 bit files
371 - examples to go with it.

454 - PostScript output (esp. Beams, Slurs, etc)
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)

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...)
