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
11 * latex bla.tex broken (titles / \lilyfooter stuff?)
13 * --safe: disallow backslashes, disallow \include.
15 * fix rounding stuff in number->string
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.

52 * \shape 1st dim skipped?
54 * fix marks/barnumbers/marginal notes

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 }

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)
91 * revise documentation
95 * junking \skip req in lyrics
102 - mix engraver hacking with music ?
103 - \once\property KEY = VAL

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

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

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

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

361 * use properties for:
366 - bartypes (get rid of derived Span_bar_engravers)
371 - optimal pagebreaking.
373 * Unicode support? -> man 7 unicode
376 - detect of 16/8 bit files
377 - examples to go with it.
380 - write a faster Spring_spacer (without matrices if possible)

407 - use dstream feature in mi2mu
408 - integrate IO checking into stream class
415 * add to MIDI output:

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

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