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.

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

61 rfheel = \script { "fheel" 0 0 1 0 0 }
62 lftoe = \script { "ftoe" 0 0 -1 0 0 }
63 rftoe = \script { "ftoe" 0 0 1 0 0 }
67 portato= \script { "portato" 0 -1 0 1 0 }
71 * move option processing out of gh_enter
73 * check out GCC signatures?
75 * Align_element::padding ?
77 * uniformise property names.
79 * ydirection <-> yDirection
81 * typo checks on property names?
83 * make engraver hacking robust.
85 * --safe: disallow backslashes, disallow \include.
87 * use streambufs and iostream
88 to provide IO handling for TeX stream, mudela stream, data-file.
90 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
92 * strip EXEs before installing
94 * zip target for binary windows dist (JBR)
96 * revise documentation
100 * junking \skip req in lyrics
103 - \type -> \context ?
107 - mix engraver hacking with music ?

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

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

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

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

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

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

561 * adaptive accidental spacing.
563 * handle EOF graciously in error messages.
565 * centered whole rest
567 * declare notenametab?
569 * midi esp.: use I32 iso int where 32 bits are needed (or assumed...)
572 - A decent scalar type
