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
10 * uniformise property names.
12 ydirection <-> yDirection
14 * typo checks on property names?
18 * make engraver hacking robust.
20 * fix LOCALE settings, and \def\foo{2,000pt} output
22 * use streambufs and iostream
23 to provide IO handling for TeX stream, mudela stream, data-file.
25 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
27 * strip EXEs before installing
29 * zip target for binary windows dist (JBR)
31 * repeat bars: need distance after ":|" and before "|:"
35 * revise documentation
39 * junking \skip req in lyrics
41 * \shape 1st dim skipped?
46 - general plet mechanism.
48 \plet 2/3 { c8 c8 c8 }
52 Music: PLET int '/' int Music
58 - mix engraver hacking with music ?
59 - \once\property KEY = VAL
60 - \addtranslator, \removetranslator
61 - junk ^ and _ for scripts
65 * install TeX stuff into tex/generic directory.
67 * percussion note heads
73 * make separate translation property list.
75 * make GNU style webpages.
77 * There seems to be an install error in lilypond-1.0.0. Most of the
78 files in the "init" directory don't get installed in the
79 /usr/local/share/lilypond directory. The files installed are of
80 the form feta*.ly. In particular init.ly doesn't get installed.
81 I installed the files by hand and then the system seems to work.
83 * midi_instrument -> midiInstrument
85 * horizontal centering of dynamics
87 * \font\fontA=feta20.afm (.afm?)
91 * stable make/config stuff
93 * stemup/stemdown; see test/updown.fly
94 - check examples; add \type Staff hither and thether
96 * $DEPENDENCIES_OUTPUT support
98 * use a fake-yodl.sh to mimick yodl when yodl is not installed
102 * fix weird behaviour when .AFMs not found.
105 gs: Error: /undefined in draw_beam
108 * run texhash after installing .tex
110 * fix vertical alignment and stafflines
112 * GrandStaff needs more work -- I want a single word
113 `harpsichord' to the left of the grandstaff, not one on each
114 stave. (Organ staff -- with separate pedal -- but common
115 properties may be something to think about. Of course for
116 organ you want to be able to give stop indications on the way
117 through, so the \property Voice.Instrument would be a stop,
118 and \property GrandStaff.instrument would be PipeOrgan...)
120 * make Tie_req a "command" { <c g> ~ <c g> }
124 * revise the Score_priority_align_engraver concept. It sucks.
128 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
129 ydirection and hshift preset
131 * *.yo: fix pod manpage layout legacy
133 * text-items clash with stems/beams
135 * --include, -I option for ly2dvi (pass on to lily)
137 * fix placement of beam-less abbrev
140 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
141 {\voicetwo cis,4 r r | r2. | r1 }> |
144 * try to use template<Type> iso MACRO(Type)
146 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
147 think about, analogous to pitch:
148 * { a4 a16 } c <-- duration of c?
149 * <a4 b8> c <-- duration of c?
153 * fix audio-items (don't use (input) requests, but copy data)
155 * junk My_lily_parser::abbrev_beam_type_i_
157 * make sure all ex's have a mudela-version
159 * do rest-collisions for Multi_measure_rests as well.
161 * split error/warning in error/warning/non_fatal_error
163 * add a Duration_convert member to Duration_iter to set parameters.
164 Junk global duration settings.
168 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
170 * minimum length second part broken tie
172 * en-,discouraged linebreaking:
173 - handle DISALLOW < penalty > FORCE
174 - discourage breaking of slurs
179 * fix variable define/lookup parser global<->paper
181 * fix title/instrument placements; see input/test/title.ly
183 * <\voiceone c4. \voicetwo c4>
185 * add full cello suites to web site (kom op, Maarten!)
187 * Rethink Time_description
188 * \cadenza , \meter, \grouping should all be \properties
193 - abbreviation-beam -> (measured/unmeasured) tremolo
194 - partial -> anacrouse
196 * libtoolize flowerlib
200 * robustify Beam (in case of no stems, 32nd notes)
202 * decentralised spring factory
204 * move paper vars into engraver properties
206 * check for groff / troff/ nroff et
208 * more intelligent file searching
210 - make LilyPond fully relocatable
212 * use kpsepath to find all TeX dirs
217 - break-up heavily-nested score blocks
219 * disable spaces in TeX stuff
221 * handle ^C for tmp/file creation.
223 * dots & rest collisions.
231 * versioning for Feta
233 * the warning about the negative slur/tie length appears twice
236 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
239 * the bracket is ugly (wings are too parabolic, should be more circular)
241 * better hshift (dots, distance, head dependent)
243 * clefs (AG): The "8" should appear closer to the actual clef,
246 * scoping for properties?
249 \multi 2 < { \stemup .. } { \stemdown .. } >
253 this modifies \stem for the c2
255 * put errorlevel in Input class
259 * integrate midi-elts from mi2mu and lily?
261 * cautionary accidental
264 FMR: Free memory read:
265 * This is occurring while in:
266 Bar_column::do_substitute_dependency(Score_element*,Score_element*) [bar
268 Score_element::unlink() [score-elem.cc:383]

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

304 * xdvi: PS in magnifying glass.
306 * GNU diff 2.7: diff -rN does not see a new directory with empty file
308 * GNU patch 2.1: <must find simple example> if patch chokes on a
309 hunk, or on allegedly unsorted hunks in a diff, it may stop
310 without a trace of failure (create .rej file, print error or
311 dump core) and just ignore any further diffs.
315 f = fopen ("/dev/null", "r")
320 * GNU indent: handle C++
322 * GNU make: move hardcoded builtin rules to runtime ?

354 * use properties for:
359 - bartypes (get rid of derived Span_bar_engravers)
364 - optimal pagebreaking.
366 * Unicode support? -> man 7 unicode
369 - detect of 16/8 bit files

447 * Output an output format independent (ofi) typeset file; and
448 make ofi2 TeX, MusiXTex, Display PostScript, PostScript,
449 Ascii... interpreters. (difficult)
452 - Common Music Notation
453 - PostScript output (esp. Beams, Slurs, etc)
454 - Move all Score_elems, into libmutype.a
459 - Doc (C) stuff of sheet music
460 - a better format? SGML? TeX? Info?
463 * more spanners (smallish)
467 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
469 - doc on Rhythmic_grouping
470 - general shaving on Beam and Stem
472 - separate visual from rhythmic info even more
474 - endbeam req should be *after* the duration, so you can do
480 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
481 - set different line sizes / thicknesses
482 - beam stem showthrough, inter beam sizes (french vs german style)
485 - left/right note balls should be handled by Collision:
486 < \multi 2; { \stem 1; <b c> } { <f as b> } >
489 - merge key{item} & localkey{item}?
491 - spacing, national styles?
494 - redo Notehead to allow digits as heads
495 - add a \tablature {} lexer mode for easy entering
497 * should adjust stemlength for flag number.

510 * neatly (and readably) expressing concurrent
525 * relative mode for pitch entering
529 * configure pitch_byte

539 * progress when creating MIDI elts.
541 * A range for context errors (eg. mark both { and }. )
543 * lyric in staff (sharpsharp in staff, text below)
547 * write Dynamic_line (to group dynamics horizontally)
549 * use Real for all y positions.
550 - use translate_axis( .. ,Y_AXIS) iso separate variables.

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