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
16 \notes { \property Staff.defaultclef = bass a b c d }
21 \type "Line_group_engraver_group";
22 \consists "Bar_engraver";
23 \consists "Clef_engraver";
24 \consists "Key_engraver";
25 \consists "Local_key_engraver";
26 \consists "Time_signature_engraver";
27 \consists "Staff_sym_engraver";
28 \consists "Collision_engraver";
29 \consists "Rest_collision_engraver";
30 \consists "Separating_line_group_engraver";
36 * typo checks on property names?
40 * make engraver hacking robust.
42 * fix LOCALE settings, and \def\foo{2,000pt} output
44 * use streambufs and iostream
45 to provide IO handling for TeX stream, mudela stream, data-file.
47 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
49 * strip EXEs before installing
51 * zip target for binary windows dist (JBR)
53 * repeat bars: need distance after ":|" and before "|:"
57 * revise documentation
61 * junking \skip req in lyrics
63 * \shape 1st dim skipped?
68 - general plet mechanism.
70 \plet 2/3 { c8 c8 c8 }
74 Music: PLET int '/' int Music
80 - mix engraver hacking with music ?
81 - \once\property KEY = VAL
82 - \addtranslator, \removetranslator
83 - junk ^ and _ for scripts
87 * install TeX stuff into tex/generic directory.
89 * percussion note heads
95 * make separate translation property list.
97 * make GNU style webpages.
99 * There seems to be an install error in lilypond-1.0.0. Most of the
100 files in the "init" directory don't get installed in the
101 /usr/local/share/lilypond directory. The files installed are of
102 the form feta*.ly. In particular init.ly doesn't get installed.
103 I installed the files by hand and then the system seems to work.
105 * midi_instrument -> midiInstrument
107 * horizontal centering of dynamics
109 * \font\fontA=feta20.afm (.afm?)
113 * stable make/config stuff
115 * stemup/stemdown; see test/updown.fly
116 - check examples; add \type Staff hither and thether
118 * $DEPENDENCIES_OUTPUT support
120 * use a fake-yodl.sh to mimick yodl when yodl is not installed
124 * fix weird behaviour when .AFMs not found.
127 gs: Error: /undefined in draw_beam
130 * run texhash after installing .tex
132 * fix vertical alignment and stafflines
134 * GrandStaff needs more work -- I want a single word
135 `harpsichord' to the left of the grandstaff, not one on each
136 stave. (Organ staff -- with separate pedal -- but common
137 properties may be something to think about. Of course for
138 organ you want to be able to give stop indications on the way
139 through, so the \property Voice.Instrument would be a stop,
140 and \property GrandStaff.instrument would be PipeOrgan...)
142 * make Tie_req a "command" { <c g> ~ <c g> }
146 * revise the Score_priority_align_engraver concept. It sucks.
150 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
151 ydirection and hshift preset
153 * *.yo: fix pod manpage layout legacy
155 * text-items clash with stems/beams
157 * --include, -I option for ly2dvi (pass on to lily)
159 * fix placement of beam-less abbrev
162 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
163 {\voicetwo cis,4 r r | r2. | r1 }> |
166 * try to use template<Type> iso MACRO(Type)
168 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
169 think about, analogous to pitch:
170 * { a4 a16 } c <-- duration of c?
171 * <a4 b8> c <-- duration of c?
175 * fix audio-items (don't use (input) requests, but copy data)
177 * junk My_lily_parser::abbrev_beam_type_i_
179 * make sure all ex's have a mudela-version
181 * do rest-collisions for Multi_measure_rests as well.
183 * split error/warning in error/warning/non_fatal_error
185 * add a Duration_convert member to Duration_iter to set parameters.
186 Junk global duration settings.
190 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
192 * minimum length second part broken tie
194 * en-,discouraged linebreaking:
195 - handle DISALLOW < penalty > FORCE
196 - discourage breaking of slurs
201 * fix variable define/lookup parser global<->paper
203 * fix title/instrument placements; see input/test/title.ly
205 * <\voiceone c4. \voicetwo c4>
207 * add full cello suites to web site (kom op, Maarten!)
209 * Rethink Time_description
210 * \cadenza , \meter, \grouping should all be \properties
215 - abbreviation-beam -> (measured/unmeasured) tremolo
216 - partial -> anacrouse
218 * libtoolize flowerlib
222 * robustify Beam (in case of no stems, 32nd notes)
224 * decentralised spring factory
226 * move paper vars into engraver properties
228 * check for groff / troff/ nroff et
230 * more intelligent file searching
232 - make LilyPond fully relocatable
234 * use kpsepath to find all TeX dirs
239 - break-up heavily-nested score blocks
241 * disable spaces in TeX stuff
243 * handle ^C for tmp/file creation.
245 * dots & rest collisions.
253 * versioning for Feta
255 * the warning about the negative slur/tie length appears twice
258 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
261 * the bracket is ugly (wings are too parabolic, should be more circular)
263 * better hshift (dots, distance, head dependent)
265 * clefs (AG): The "8" should appear closer to the actual clef,
268 * scoping for properties?
271 \multi 2 < { \stemup .. } { \stemdown .. } >
275 this modifies \stem for the c2
277 * put errorlevel in Input class
281 * integrate midi-elts from mi2mu and lily?
283 * cautionary accidental
286 FMR: Free memory read:
287 * This is occurring while in:

324 * gcc 2.8.1: see ice and RESIZE_ICE
326 * xdvi: PS in magnifying glass.
328 * GNU diff 2.7: diff -rN does not see a new directory with empty file
330 * GNU patch 2.1: <must find simple example> if patch chokes on a
331 hunk, or on allegedly unsorted hunks in a diff, it may stop
332 without a trace of failure (create .rej file, print error or
333 dump core) and just ignore any further diffs.
337 f = fopen ("/dev/null", "r")
342 * GNU indent: handle C++
344 * GNU make: move hardcoded builtin rules to runtime ?
347 - 'double-fix' mode: ignore identical fix, rather than suggest
348 to revert patch direction when (more or less? exactly) the same
354 - fix position of bar number

376 * use properties for:
381 - bartypes (get rid of derived Span_bar_engravers)
386 - optimal pagebreaking.
388 * Unicode support? -> man 7 unicode
391 - detect of 16/8 bit files

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

532 * neatly (and readably) expressing concurrent
547 * relative mode for pitch entering
551 * configure pitch_byte

561 * progress when creating MIDI elts.
563 * A range for context errors (eg. mark both { and }. )
565 * lyric in staff (sharpsharp in staff, text below)
569 * write Dynamic_line (to group dynamics horizontally)
571 * use Real for all y positions.
572 - use translate_axis( .. ,Y_AXIS) iso separate variables.

576 * adaptive accidental spacing.
578 * handle EOF graciously in error messages.
580 * centered whole rest
582 * declare notenametab?
584 * midi esp.: use I32 iso int where 32 bits are needed (or assumed...)
587 - A decent scalar type
