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 * fix LOCALE settings, and \def\foo{2,000pt} output
14 * use streambufs and iostream
15 to provide IO handling for TeX stream, mudela stream, data-file.
17 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
19 * strip EXEs before installing
21 * zip target for binary windows dist (JBR)
23 * repeat bars: need distance after ":|" and before "|:"
27 * revise documentation
32 - general plet mechanism.
34 \plet 2/3 { c8 c8 c8 }
38 Music: PLET int '/' int Music
45 - mix engraver hacking with music ?
46 - \once\property KEY = VAL
47 - \addtranslator, \removetranslator
48 - junk ^ and _ for scripts
50 * install TeX stuff into tex/generic directory.
52 * preformatted .info stuff.
54 * percussion note heads
60 * make separate translation property list.
62 * make GNU style webpages.
64 * There seems to be an install error in lilypond-1.0.0. Most of the
65 files in the "init" directory don't get installed in the
66 /usr/local/share/lilypond directory. The files installed are of
67 the form feta*.ly. In particular init.ly doesn't get installed.
68 I installed the files by hand and then the system seems to work.
70 * midi_instrument -> midiInstrument
72 * horizontal centering of dynamics
74 * \font\fontA=feta20.afm (.afm?)
78 * stable make/config stuff
80 * stemup/stemdown; see test/updown.fly
81 - check examples; add \type Staff hither and thether
83 * $DEPENDENCIES_OUTPUT support
85 * use a fake-yodl.sh to mimick yodl when yodl is not installed
89 * fix weird behaviour when .AFMs not found.
92 gs: Error: /undefined in draw_beam
95 * run texhash after installing .tex
97 * fix vertical alignment and stafflines
99 * GrandStaff needs more work -- I want a single word
100 `harpsichord' to the left of the grandstaff, not one on each
101 stave. (Organ staff -- with separate pedal -- but common
102 properties may be something to think about. Of course for
103 organ you want to be able to give stop indications on the way
104 through, so the \property Voice.Instrument would be a stop,
105 and \property GrandStaff.instrument would be PipeOrgan...)
107 * make Tie_req a "command" { <c g> ~ <c g> }
111 * revise the Score_priority_align_engraver concept. It sucks.
115 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
116 ydirection and hshift preset
118 * *.yo: fix pod manpage layout legacy
120 * text-items clash with stems/beams
122 * --include, -I option for ly2dvi (pass on to lily)
124 * fix placement of beam-less abbrev
127 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
128 {\voicetwo cis,4 r r | r2. | r1 }> |
131 * try to use template<Type> iso MACRO(Type)
133 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
134 think about, analogous to pitch:
135 * { a4 a16 } c <-- duration of c?
136 * <a4 b8> c <-- duration of c?
140 * fix audio-items (don't use (input) requests, but copy data)
142 * junk My_lily_parser::abbrev_beam_type_i_
144 * make sure all ex's have a mudela-version
146 * do rest-collisions for Multi_measure_rests as well.
148 * split error/warning in error/warning/non_fatal_error
150 * add a Duration_convert member to Duration_iter to set parameters.
151 Junk global duration settings.
155 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
157 * minimum length second part broken tie
159 * en-,discouraged linebreaking:
160 - handle DISALLOW < penalty > FORCE
161 - discourage breaking of slurs
166 * fix variable define/lookup parser global<->paper
168 * fix title/instrument placements; see input/test/title.ly
170 * <\voiceone c4. \voicetwo c4>
172 * add full cello suites to web site (kom op, Maarten!)
174 * Rethink Time_description
175 * \cadenza , \meter, \grouping should all be \properties
180 - abbreviation-beam -> (measured/unmeasured) tremolo
181 - partial -> anacrouse
183 * libtoolize flowerlib
187 * robustify Beam (in case of no stems, 32nd notes)
189 * decentralised spring factory
191 * move paper vars into engraver properties
193 * check for groff / troff/ nroff et
195 * more intelligent file searching
197 - make LilyPond fully relocatable
199 * use kpsepath to find all TeX dirs
204 - break-up heavily-nested score blocks
206 * disable spaces in TeX stuff
208 * handle ^C for tmp/file creation.
210 * dots & rest collisions.
218 * versioning for Feta
220 * the warning about the negative slur/tie length appears twice
223 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
226 * the bracket is ugly (wings are too parabolic, should be more circular)
228 * better hshift (dots, distance, head dependent)
230 * clefs (AG): The "8" should appear closer to the actual clef,
233 * scoping for properties?
236 \multi 2 < { \stemup .. } { \stemdown .. } >
240 this modifies \stem for the c2
242 * put errorlevel in Input class
246 * integrate midi-elts from mi2mu and lily?
248 * cautionary accidental
251 FMR: Free memory read:
252 * This is occurring while in:
253 Bar_column::do_substitute_dependency(Score_element*,Score_element*) [bar
255 Score_element::unlink() [score-elem.cc:383]

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

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

341 * use properties for:
346 - bartypes (get rid of derived Span_bar_engravers)
351 - optimal pagebreaking.
353 * Unicode support? -> man 7 unicode
356 - detect of 16/8 bit files

409 - make encapsulated spacing problems.
411 * accidentals per Voice_group
413 * Output class, handles : (smallish)

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

497 * neatly (and readably) expressing concurrent
512 * relative mode for pitch entering
516 * configure pitch_byte

526 * progress when creating MIDI elts.
528 * A range for context errors (eg. mark both { and }. )
530 * lyric in staff (sharpsharp in staff, text below)
534 * write Dynamic_line (to group dynamics horizontally)
536 * use Real for all y positions.
537 - use translate_axis( .. ,Y_AXIS) iso separate variables.
539 * half-sharps, half-flats
541 * adaptive accidental spacing.
543 * handle EOF graciously in error messages.
545 * centered whole rest
547 * declare notenametab?
549 * midi esp.: use I32 iso int where 32 bits are needed (or assumed...)
552 - A decent scalar type
