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 * --safe: disallow backslashes, disallow \include.
19 * \breathmark TeX macro
21 * configure error if GUILE 1.3 not found
25 * add new glyphs to font.ly
27 * formatting of input stuff.
29 * \notes{ a \< b \cr } vs \notes{ a \< b \! }
31 * if possible, it might be nice for a warning to appear if someone does
32 \translator with no name and without assigning it to an
39 * fix singleStaffBracket
41 * repeat bars: need distance after ":|" and before "|:"
43 * The time signature warnings still remain, will be fixed later.
45 Summary of minor spelling irregularities:
46 - capitalization/use of underscores in property names
50 * repeat bars: need distance after ":|" and before "|:"
52 * \shape 1st dim skipped?
54 * fix marks/barnumbers/marginal notes
57 lbheel = \script { "bheel" 0 0 -1 0 0 }
58 rbheel = \script { "bheel" 0 0 1 0 0 }
59 lbtoe = \script { "btoe" 0 0 -1 0 0 }
60 rbtoe = \script { "btoe" 0 0 1 0 0 }
61 lfheel = \script { "fheel" 0 0 -1 0 0 }
62 rfheel = \script { "fheel" 0 0 1 0 0 }
63 lftoe = \script { "ftoe" 0 0 -1 0 0 }
64 rftoe = \script { "ftoe" 0 0 1 0 0 }
68 portato= \script { "portato" 0 -1 0 1 0 }
70 * Align_element::padding ?
72 * uniformise property names.
74 * ydirection <-> yDirection
76 * typo checks on property names?
78 * make engraver hacking robust.
80 * use streambufs and iostream
81 to provide IO handling for TeX stream, mudela stream, data-file.
83 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
85 * strip EXEs before installing
87 * zip target for binary windows dist (JBR)
89 * revise documentation
93 * junking \skip req in lyrics
100 - mix engraver hacking with music ?
101 - \once\property KEY = VAL
102 - \addtranslator, \removetranslator
103 - junk ^ and _ for scripts

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

176 * try to use template<Type> iso MACRO(Type)
178 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
179 think about, analogous to pitch:
180 * { a4 a16 } c <-- duration of c?
181 * <a4 b8> c <-- duration of c?
185 * fix audio-items (don't use (input) requests, but copy data)
187 * junk My_lily_parser::abbrev_beam_type_i_
189 * make sure all ex's have a mudela-version
191 * do rest-collisions for Multi_measure_rests as well.

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

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

359 * use properties for:
364 - bartypes (get rid of derived Span_bar_engravers)
369 - optimal pagebreaking.
371 * Unicode support? -> man 7 unicode
374 - detect of 16/8 bit files
375 - examples to go with it.

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)
488 - left/right note balls should be handled by Collision:
489 < \multi 2; { \stem 1; <b c> } { <f as b> } >
492 - merge key{item} & localkey{item}?
493 - spacing, national styles?
496 - redo Notehead to allow digits as heads

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