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
13 * fix \n after proccing
15 Summary of minor spelling irregularities:
16 > capitalization/use of underscores in property names
17 > \lyric vs \notes \lyric vs \type Lyrics (\lyric should have an -s)
21 * repeat bars: need distance after ":|" and before "|:"
23 * \shape 1st dim skipped?
25 * fix marks/barnumbers/marginal notes
30 * uniformise property names.
32 * ydirection <-> yDirection
34 * typo checks on property names?
38 * make engraver hacking robust.
40 * use streambufs and iostream
41 to provide IO handling for TeX stream, mudela stream, data-file.
43 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
45 * strip EXEs before installing
47 * zip target for binary windows dist (JBR)
51 * revise documentation
55 * junking \skip req in lyrics
58 - general plet mechanism.
60 \plet 2/3 { c8 c8 c8 }
64 Music: PLET int '/' int Music
70 - mix engraver hacking with music ?
71 - \once\property KEY = VAL
72 - \addtranslator, \removetranslator
73 - junk ^ and _ for scripts
77 * install TeX stuff into tex/generic directory.
79 * /etc/profile.d support for RPM.
81 * percussion note heads
87 * make GNU style webpages.
89 * There seems to be an install error in lilypond-1.0.0. Most of the
90 files in the "init" directory don't get installed in the
91 /usr/local/share/lilypond directory. The files installed are of
92 the form feta*.ly. In particular init.ly doesn't get installed.
93 I installed the files by hand and then the system seems to work.
95 * midi_instrument -> midiInstrument
97 * horizontal centering of dynamics
99 * \font\fontA=feta20.afm (.afm?)
103 * stable make/config stuff
105 * stemup/stemdown; see test/updown.fly
106 - check examples; add \type Staff hither and thether
108 * $DEPENDENCIES_OUTPUT support
110 * use a fake-yodl.sh to mimick yodl when yodl is not installed
114 * fix weird behaviour when .AFMs not found.
117 gs: Error: /undefined in draw_beam
120 * run texhash after installing .tex
122 * fix vertical alignment and stafflines
124 * GrandStaff needs more work -- I want a single word
125 `harpsichord' to the left of the grandstaff, not one on each
126 stave. (Organ staff -- with separate pedal -- but common
127 properties may be something to think about. Of course for
128 organ you want to be able to give stop indications on the way
129 through, so the \property Voice.Instrument would be a stop,
130 and \property GrandStaff.instrument would be PipeOrgan...)
132 * make Tie_req a "command" { <c g> ~ <c g> }
136 * revise the Score_priority_align_engraver concept. It sucks.
140 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
141 ydirection and hshift preset
143 * *.yo: fix pod manpage layout legacy
145 * text-items clash with stems/beams
147 * --include, -I option for ly2dvi (pass on to lily)
149 * fix placement of beam-less abbrev
152 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
153 {\voicetwo cis,4 r r | r2. | r1 }> |
156 * try to use template<Type> iso MACRO(Type)
158 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
159 think about, analogous to pitch:
160 * { a4 a16 } c <-- duration of c?
161 * <a4 b8> c <-- duration of c?
165 * fix audio-items (don't use (input) requests, but copy data)
167 * junk My_lily_parser::abbrev_beam_type_i_
169 * make sure all ex's have a mudela-version
171 * do rest-collisions for Multi_measure_rests as well.
173 * split error/warning in error/warning/non_fatal_error
175 * add a Duration_convert member to Duration_iter to set parameters.
176 Junk global duration settings.
180 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
182 * minimum length second part broken tie
184 * en-,discouraged linebreaking:
185 - handle DISALLOW < penalty > FORCE
186 - discourage breaking of slurs
191 * fix variable define/lookup parser global<->paper
193 * fix title/instrument placements; see input/test/title.ly
195 * <\voiceone c4. \voicetwo c4>
197 * add full cello suites to web site (kom op, Maarten!)
199 * Rethink Time_description
200 * \cadenza , \meter, \grouping should all be \properties
205 - abbreviation-beam -> (measured/unmeasured) tremolo
206 - partial -> anacrouse
208 * libtoolize flowerlib
212 * robustify Beam (in case of no stems, 32nd notes)
214 * decentralised spring factory
216 * move paper vars into engraver properties
218 * check for groff / troff/ nroff et
220 * more intelligent file searching
222 - make LilyPond fully relocatable
224 * use kpsepath to find all TeX dirs
229 - break-up heavily-nested score blocks
231 * disable spaces in TeX stuff
233 * handle ^C for tmp/file creation.
235 * dots & rest collisions.
243 * versioning for Feta
245 * the warning about the negative slur/tie length appears twice
248 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
251 * the bracket is ugly (wings are too parabolic, should be more circular)
253 * better hshift (dots, distance, head dependent)
255 * clefs (AG): The "8" should appear closer to the actual clef,
258 * scoping for properties?
261 \multi 2 < { \stemup .. } { \stemdown .. } >
265 this modifies \stem for the c2
267 * put errorlevel in Input class
271 * integrate midi-elts from mi2mu and lily?
273 * cautionary accidental
276 FMR: Free memory read:
277 * This is occurring while in:

316 * xdvi: PS in magnifying glass.
318 * GNU diff 2.7: diff -rN does not see a new directory with empty file
320 * GNU patch 2.1: <must find simple example> if patch chokes on a
321 hunk, or on allegedly unsorted hunks in a diff, it may stop
322 without a trace of failure (create .rej file, print error or
323 dump core) and just ignore any further diffs.
327 f = fopen ("/dev/null", "r")
332 * GNU indent: handle C++
334 * GNU make: move hardcoded builtin rules to runtime ?
337 - 'double-fix' mode: ignore identical fix, rather than suggest
338 to revert patch direction when (more or less? exactly) the same
344 - fix position of bar number
345 - stack scripts in chords:
346 % fingering: footing:

366 * use properties for:
371 - bartypes (get rid of derived Span_bar_engravers)
376 - optimal pagebreaking.
378 * Unicode support? -> man 7 unicode
381 - detect of 16/8 bit files
382 - examples to go with it.

433 (which is at Voice_gravs level)
434 - make encapsulated spacing problems.
436 * accidentals per Voice_group
438 * Output class, handles : (smallish)
439 - help text /(c) notice?
441 - warning /errors/progress
442 - abort on error/warning; exit status
443 - quiet/ignore-version options
448 * elaborate Staff_side baseclass:
455 - PS lines to .eps files
456 - write custom prolog
459 * Output an output format independent (ofi) typeset file; and
460 make ofi2 TeX, MusiXTex, Display PostScript, PostScript,
461 Ascii... interpreters. (difficult)
464 - Common Music Notation
465 - PostScript output (esp. Beams, Slurs, etc)
466 - Move all Score_elems, into libmutype.a
471 - Doc (C) stuff of sheet music
472 - a better format? SGML? TeX? Info?
475 * more spanners (smallish)
479 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
481 - doc on Rhythmic_grouping
482 - general shaving on Beam and Stem
484 - separate visual from rhythmic info even more
486 - endbeam req should be *after* the duration, so you can do
492 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
493 - set different line sizes / thicknesses
494 - beam stem showthrough, inter beam sizes (french vs german style)
497 - left/right note balls should be handled by Collision:
498 < \multi 2; { \stem 1; <b c> } { <f as b> } >
501 - merge key{item} & localkey{item}?
503 - spacing, national styles?
506 - redo Notehead to allow digits as heads
507 - add a \tablature {} lexer mode for easy entering
509 * should adjust stemlength for flag number.
512 - caching breakpoints

522 * neatly (and readably) expressing concurrent
537 * relative mode for pitch entering
541 * configure pitch_byte

551 * progress when creating MIDI elts.
553 * A range for context errors (eg. mark both { and }. )
555 * lyric in staff (sharpsharp in staff, text below)
559 * write Dynamic_line (to group dynamics horizontally)
561 * use Real for all y positions.
562 - use translate_axis( .. ,Y_AXIS) iso separate variables.
564 * half-sharps, half-flats
566 * adaptive accidental spacing.
568 * handle EOF graciously in error messages.
570 * centered whole rest
572 * declare notenametab?
574 * midi esp.: use I32 iso int where 32 bits are needed (or assumed...)
577 - A decent scalar type
