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
15 * repeat bars: need distance after ":|" and before "|:"
17 * \shape 1st dim skipped?
19 * fix marks/barnumbers/marginal notes
24 * uniformise property names.
26 * ydirection <-> yDirection
28 * typo checks on property names?
32 * make engraver hacking robust.
34 * fix LOCALE settings, and \def\foo{2,000pt} output
36 * use streambufs and iostream
37 to provide IO handling for TeX stream, mudela stream, data-file.
39 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
41 * strip EXEs before installing
43 * zip target for binary windows dist (JBR)
47 * revise documentation
51 * junking \skip req in lyrics
54 - general plet mechanism.
56 \plet 2/3 { c8 c8 c8 }
60 Music: PLET int '/' int Music
66 - mix engraver hacking with music ?
67 - \once\property KEY = VAL
68 - \addtranslator, \removetranslator
69 - junk ^ and _ for scripts
73 * install TeX stuff into tex/generic directory.
75 * /etc/profile.d support for RPM.
77 * percussion note heads
83 * make GNU style webpages.
85 * There seems to be an install error in lilypond-1.0.0. Most of the
86 files in the "init" directory don't get installed in the
87 /usr/local/share/lilypond directory. The files installed are of
88 the form feta*.ly. In particular init.ly doesn't get installed.
89 I installed the files by hand and then the system seems to work.
91 * midi_instrument -> midiInstrument
93 * horizontal centering of dynamics
95 * \font\fontA=feta20.afm (.afm?)
99 * stable make/config stuff
101 * stemup/stemdown; see test/updown.fly
102 - check examples; add \type Staff hither and thether
104 * $DEPENDENCIES_OUTPUT support
106 * use a fake-yodl.sh to mimick yodl when yodl is not installed
110 * fix weird behaviour when .AFMs not found.
113 gs: Error: /undefined in draw_beam
116 * run texhash after installing .tex
118 * fix vertical alignment and stafflines
120 * GrandStaff needs more work -- I want a single word
121 `harpsichord' to the left of the grandstaff, not one on each
122 stave. (Organ staff -- with separate pedal -- but common
123 properties may be something to think about. Of course for
124 organ you want to be able to give stop indications on the way
125 through, so the \property Voice.Instrument would be a stop,
126 and \property GrandStaff.instrument would be PipeOrgan...)
128 * make Tie_req a "command" { <c g> ~ <c g> }
132 * revise the Score_priority_align_engraver concept. It sucks.
136 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
137 ydirection and hshift preset
139 * *.yo: fix pod manpage layout legacy
141 * text-items clash with stems/beams
143 * --include, -I option for ly2dvi (pass on to lily)
145 * fix placement of beam-less abbrev
148 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
149 {\voicetwo cis,4 r r | r2. | r1 }> |
152 * try to use template<Type> iso MACRO(Type)
154 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
155 think about, analogous to pitch:
156 * { a4 a16 } c <-- duration of c?
157 * <a4 b8> c <-- duration of c?
161 * fix audio-items (don't use (input) requests, but copy data)
163 * junk My_lily_parser::abbrev_beam_type_i_
165 * make sure all ex's have a mudela-version
167 * do rest-collisions for Multi_measure_rests as well.
169 * split error/warning in error/warning/non_fatal_error
171 * add a Duration_convert member to Duration_iter to set parameters.
172 Junk global duration settings.
176 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
178 * minimum length second part broken tie
180 * en-,discouraged linebreaking:
181 - handle DISALLOW < penalty > FORCE
182 - discourage breaking of slurs
187 * fix variable define/lookup parser global<->paper
189 * fix title/instrument placements; see input/test/title.ly
191 * <\voiceone c4. \voicetwo c4>
193 * add full cello suites to web site (kom op, Maarten!)
195 * Rethink Time_description
196 * \cadenza , \meter, \grouping should all be \properties
201 - abbreviation-beam -> (measured/unmeasured) tremolo
202 - partial -> anacrouse
204 * libtoolize flowerlib
208 * robustify Beam (in case of no stems, 32nd notes)
210 * decentralised spring factory
212 * move paper vars into engraver properties
214 * check for groff / troff/ nroff et
216 * more intelligent file searching
218 - make LilyPond fully relocatable
220 * use kpsepath to find all TeX dirs
225 - break-up heavily-nested score blocks
227 * disable spaces in TeX stuff
229 * handle ^C for tmp/file creation.
231 * dots & rest collisions.
239 * versioning for Feta
241 * the warning about the negative slur/tie length appears twice
244 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
247 * the bracket is ugly (wings are too parabolic, should be more circular)
249 * better hshift (dots, distance, head dependent)
251 * clefs (AG): The "8" should appear closer to the actual clef,
254 * scoping for properties?
257 \multi 2 < { \stemup .. } { \stemdown .. } >
261 this modifies \stem for the c2
263 * put errorlevel in Input class
267 * integrate midi-elts from mi2mu and lily?
269 * cautionary accidental
272 FMR: Free memory read:
273 * This is occurring while in:
274 Bar_column::do_substitute_dependency(Score_element*,Score_element*) [bar
276 Score_element::unlink() [score-elem.cc:383]

280 Paper_score::process() [p-score.cc:203]
281 Score::run_translator(Music_output_def*) [score.cc:117]
282 * Reading 4 bytes from 0x65d3a0 in the heap.
283 * Address 0x65d3a0 is 160 bytes into a freed block at 0x65d300 of 208 bytes.

312 * xdvi: PS in magnifying glass.
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++
330 * GNU make: move hardcoded builtin rules to runtime ?
333 - 'double-fix' mode: ignore identical fix, rather than suggest
334 to revert patch direction when (more or less? exactly) the same
340 - fix position of bar number
341 - stack scripts in chords:

362 * use properties for:
367 - bartypes (get rid of derived Span_bar_engravers)
372 - optimal pagebreaking.
374 * Unicode support? -> man 7 unicode
377 - detect of 16/8 bit files
378 - examples to go with it.

429 (which is at Voice_gravs level)
430 - make encapsulated spacing problems.
432 * accidentals per Voice_group
434 * Output class, handles : (smallish)
435 - help text /(c) notice?
437 - warning /errors/progress

444 * elaborate Staff_side baseclass:
451 - PS lines to .eps files
452 - write custom prolog
455 * Output an output format independent (ofi) typeset file; and
456 make ofi2 TeX, MusiXTex, Display PostScript, PostScript,
457 Ascii... interpreters. (difficult)
460 - Common Music Notation
461 - PostScript output (esp. Beams, Slurs, etc)
462 - 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}?
499 - spacing, national styles?
502 - redo Notehead to allow digits as heads
503 - add a \tablature {} lexer mode for easy entering
505 * should adjust stemlength for flag number.

518 * neatly (and readably) expressing concurrent
533 * relative mode for pitch entering
537 * configure pitch_byte
539 * rest name configurable
543 * limit memory usage; the full coriolan takes up too much resources.
545 * fix confusing naming in Engraver vs Engraver_group_engraver (context)
547 * progress when creating MIDI elts.
549 * A range for context errors (eg. mark both { and }. )
551 * lyric in staff (sharpsharp in staff, text below)
555 * write Dynamic_line (to group dynamics horizontally)
557 * use Real for all y positions.
558 - use translate_axis( .. ,Y_AXIS) iso separate variables.
560 * half-sharps, half-flats
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
