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.

26 * \notes{ a \< b \cr } vs \notes{ a \< b \! }
28 * if possible, it might be nice for a warning to appear if someone does
29 \translator with no name and without assigning it to an
36 * fix singleStaffBracket
38 * repeat bars: need distance after ":|" and before "|:"
40 * The time signature warnings still remain, will be fixed later.
42 Summary of minor spelling irregularities:
43 - capitalization/use of underscores in property names
47 * repeat bars: need distance after ":|" and before "|:"
49 * \shape 1st dim skipped?
51 * fix marks/barnumbers/marginal notes

61 rftoe = \script { "ftoe" 0 0 1 0 0 }
65 portato= \script { "portato" 0 -1 0 1 0 }
68 * uniformise recent feta contributions.
70 * check out legal/(c) matters for scores.
72 * move option processing out of gh_enter

78 * uniformise property names.
80 * ydirection <-> yDirection
82 * typo checks on property names?
84 * make engraver hacking robust.
86 * --safe: disallow backslashes, disallow \include.
88 * use streambufs and iostream
89 to provide IO handling for TeX stream, mudela stream, data-file.
91 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
93 * strip EXEs before installing
95 * zip target for binary windows dist (JBR)
97 * revise documentation
101 * junking \skip req in lyrics
104 - \type -> \context ?
108 - mix engraver hacking with music ?
109 - \once\property KEY = VAL

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

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

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

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

365 * use properties for:
370 - bartypes (get rid of derived Span_bar_engravers)
375 - optimal pagebreaking.
377 * Unicode support? -> man 7 unicode
380 - detect of 16/8 bit files
381 - examples to go with it.
384 - write a faster Spring_spacer (without matrices if possible)
385 - relate energybound to linelen unitspace fontsize etc.

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

562 * adaptive accidental spacing.
564 * handle EOF graciously in error messages.
566 * centered whole rest
568 * declare notenametab?
570 * midi esp.: use I32 iso int where 32 bits are needed (or assumed...)
573 - A decent scalar type
575 * binsearch/hash for identifiers
577 * stafftypes: voice names/ instrument names.
581 * C meter iso 4/4, idem for alla breve, etc.
