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
12 * make engraver hacking robust.
14 * fix LOCALE settings, and \def\foo{2,000pt} output
16 * use streambufs and iostream
17 to provide IO handling for TeX stream, mudela stream, data-file.
19 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
21 * strip EXEs before installing
23 * zip target for binary windows dist (JBR)
25 * repeat bars: need distance after ":|" and before "|:"
29 * revise documentation
33 * junking \skip req in lyrics
35 * \shape 1st dim skipped?
38 - general plet mechanism.
40 \plet 2/3 { c8 c8 c8 }
44 Music: PLET int '/' int Music
50 - mix engraver hacking with music ?
51 - \once\property KEY = VAL
52 - \addtranslator, \removetranslator
53 - junk ^ and _ for scripts
57 * install TeX stuff into tex/generic directory.
59 * percussion note heads
65 * make separate translation property list.
67 * make GNU style webpages.
69 * There seems to be an install error in lilypond-1.0.0. Most of the
70 files in the "init" directory don't get installed in the
71 /usr/local/share/lilypond directory. The files installed are of
72 the form feta*.ly. In particular init.ly doesn't get installed.
73 I installed the files by hand and then the system seems to work.
75 * midi_instrument -> midiInstrument
77 * horizontal centering of dynamics
79 * \font\fontA=feta20.afm (.afm?)
83 * stable make/config stuff
85 * stemup/stemdown; see test/updown.fly
86 - check examples; add \type Staff hither and thether
88 * $DEPENDENCIES_OUTPUT support
90 * use a fake-yodl.sh to mimick yodl when yodl is not installed
94 * fix weird behaviour when .AFMs not found.
97 gs: Error: /undefined in draw_beam
100 * run texhash after installing .tex
102 * fix vertical alignment and stafflines
104 * GrandStaff needs more work -- I want a single word
105 `harpsichord' to the left of the grandstaff, not one on each
106 stave. (Organ staff -- with separate pedal -- but common
107 properties may be something to think about. Of course for
108 organ you want to be able to give stop indications on the way
109 through, so the \property Voice.Instrument would be a stop,
110 and \property GrandStaff.instrument would be PipeOrgan...)
112 * make Tie_req a "command" { <c g> ~ <c g> }
116 * revise the Score_priority_align_engraver concept. It sucks.
120 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
121 ydirection and hshift preset
123 * *.yo: fix pod manpage layout legacy
125 * text-items clash with stems/beams
127 * --include, -I option for ly2dvi (pass on to lily)
129 * fix placement of beam-less abbrev
132 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
133 {\voicetwo cis,4 r r | r2. | r1 }> |
136 * try to use template<Type> iso MACRO(Type)
138 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
139 think about, analogous to pitch:
140 * { a4 a16 } c <-- duration of c?
141 * <a4 b8> c <-- duration of c?
145 * fix audio-items (don't use (input) requests, but copy data)
147 * junk My_lily_parser::abbrev_beam_type_i_
149 * make sure all ex's have a mudela-version
151 * do rest-collisions for Multi_measure_rests as well.
153 * split error/warning in error/warning/non_fatal_error
155 * add a Duration_convert member to Duration_iter to set parameters.
156 Junk global duration settings.
160 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
162 * minimum length second part broken tie
164 * en-,discouraged linebreaking:
165 - handle DISALLOW < penalty > FORCE
166 - discourage breaking of slurs
171 * fix variable define/lookup parser global<->paper
173 * fix title/instrument placements; see input/test/title.ly
175 * <\voiceone c4. \voicetwo c4>
177 * add full cello suites to web site (kom op, Maarten!)
179 * Rethink Time_description
180 * \cadenza , \meter, \grouping should all be \properties
185 - abbreviation-beam -> (measured/unmeasured) tremolo
186 - partial -> anacrouse
188 * libtoolize flowerlib
192 * robustify Beam (in case of no stems, 32nd notes)
194 * decentralised spring factory
196 * move paper vars into engraver properties
198 * check for groff / troff/ nroff et
200 * more intelligent file searching
202 - make LilyPond fully relocatable
204 * use kpsepath to find all TeX dirs
209 - break-up heavily-nested score blocks
211 * disable spaces in TeX stuff
213 * handle ^C for tmp/file creation.
215 * dots & rest collisions.
223 * versioning for Feta
225 * the warning about the negative slur/tie length appears twice
228 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
231 * the bracket is ugly (wings are too parabolic, should be more circular)
233 * better hshift (dots, distance, head dependent)
235 * clefs (AG): The "8" should appear closer to the actual clef,
238 * scoping for properties?
241 \multi 2 < { \stemup .. } { \stemdown .. } >
245 this modifies \stem for the c2
247 * put errorlevel in Input class
251 * integrate midi-elts from mi2mu and lily?
253 * cautionary accidental
256 FMR: Free memory read:
257 * This is occurring while in:

264 Paper_score::process() [p-score.cc:203]
265 Score::run_translator(Music_output_def*) [score.cc:117]

296 * xdvi: PS in magnifying glass.
298 * GNU diff 2.7: diff -rN does not see a new directory with empty file
300 * GNU patch 2.1: <must find simple example> if patch chokes on a
301 hunk, or on allegedly unsorted hunks in a diff, it may stop
302 without a trace of failure (create .rej file, print error or
303 dump core) and just ignore any further diffs.
307 f = fopen ("/dev/null", "r")
312 * GNU indent: handle C++
314 * GNU make: move hardcoded builtin rules to runtime ?
317 - 'double-fix' mode: ignore identical fix, rather than suggest
318 to revert patch direction when (more or less? exactly) the same
324 - fix position of bar number

346 * use properties for:
351 - bartypes (get rid of derived Span_bar_engravers)
356 - optimal pagebreaking.
358 * Unicode support? -> man 7 unicode
361 - detect of 16/8 bit files
362 - examples to go with it.

439 * Output an output format independent (ofi) typeset file; and
440 make ofi2 TeX, MusiXTex, Display PostScript, PostScript,
441 Ascii... interpreters. (difficult)
444 - Common Music Notation
445 - PostScript output (esp. Beams, Slurs, etc)
446 - Move all Score_elems, into libmutype.a
451 - Doc (C) stuff of sheet music
452 - a better format? SGML? TeX? Info?
455 * more spanners (smallish)
459 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
461 - doc on Rhythmic_grouping
462 - general shaving on Beam and Stem
464 - separate visual from rhythmic info even more
466 - endbeam req should be *after* the duration, so you can do
472 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
473 - set different line sizes / thicknesses
474 - beam stem showthrough, inter beam sizes (french vs german style)
477 - left/right note balls should be handled by Collision:
478 < \multi 2; { \stem 1; <b c> } { <f as b> } >
481 - merge key{item} & localkey{item}?
483 - spacing, national styles?
486 - redo Notehead to allow digits as heads
487 - add a \tablature {} lexer mode for easy entering
489 * should adjust stemlength for flag number.
492 - caching breakpoints

502 * neatly (and readably) expressing concurrent
517 * relative mode for pitch entering
521 * configure pitch_byte
523 * rest name configurable
527 * limit memory usage; the full coriolan takes up too much resources.
529 * fix confusing naming in Engraver vs Engraver_group_engraver (context)
531 * progress when creating MIDI elts.
533 * A range for context errors (eg. mark both { and }. )
535 * lyric in staff (sharpsharp in staff, text below)
539 * write Dynamic_line (to group dynamics horizontally)
541 * use Real for all y positions.
542 - use translate_axis( .. ,Y_AXIS) iso separate variables.
544 * half-sharps, half-flats
546 * adaptive accidental spacing.
548 * handle EOF graciously in error messages.
550 * centered whole rest
552 * declare notenametab?
554 * midi esp.: use I32 iso int where 32 bits are needed (or assumed...)
557 - A decent scalar type
