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 * fix plain tex footer line.
12 * portable libs for flowerlib/lilylib
14 * install TeX stuff into tex/generic directory.
16 * preformatted .info stuff.
18 * percussion note heads
24 * make separate translation property list.
28 * make GNU style webpages.
30 * There seems to be an install error in lilypond-1.0.0. Most of the
31 files in the "init" directory don't get installed in the
32 /usr/local/share/lilypond directory. The files installed are of
33 the form feta*.ly. In particular init.ly doesn't get installed.
34 I installed the files by hand and then the system seems to work.
36 * midi_instrument -> midiInstrument
38 * horizontal centering of dynamics
40 * \font\fontA=feta20.afm (.afm?)
44 * stable make/config stuff
46 * stemup/stemdown; see test/updown.fly
47 - check examples; add \type Staff hither and thether
49 * $DEPENDENCIES_OUTPUT support
51 * use a fake-yodl.sh to mimick yodl when yodl is not installed
55 * fix weird behaviour when .AFMs not found.
58 gs: Error: /undefined in draw_beam
61 * run texhash after installing .tex
63 * fix vertical alignment and stafflines
65 *GrandStaff needs more work -- I want a single word `harpsichord' to the
66 left of the grandstaff, not one on each stave.
67 (Organ staff -- with separate pedal -- but common properties may be
68 something to think about. Of course for organ you want to be able
69 to give stop indications on the way through, so the \property
70 Voice.Instrument would be a stop, and \property
71 GrandStaff.instrument would be PipeOrgan...)
74 * make Tie_req a "command" { <c g> ~ <c g> }
78 * mix engraver hacking with music ?
80 * revise the Score_priority_align_engraver concept. It sucks.
84 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
85 ydirection and hshift preset
88 - /usr/bin/make-patch?
90 * *.yo: fix pod manpage layout legacy
92 * text-items clash with stems/beams
94 * --include, -I option for ly2dvi (pass on to lily)
96 * fix placement of beam-less abbrev
99 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
100 {\voicetwo cis,4 r r | r2. | r1 }> |
103 * try to use template<Type> iso MACRO(Type)
105 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
106 think about, analogous to pitch:
107 * { a4 a16 } c <-- duration of c?
108 * <a4 b8> c <-- duration of c?
112 * fix audio-items (don't use (input) requests, but copy data)
114 * junk My_lily_parser::abbrev_beam_type_i_
116 * make sure all ex's have a mudela-version
118 * do rest-collisions for Multi_measure_rests as well.
120 * split error/warning in error/warning/non_fatal_error
122 * add a Duration_convert member to Duration_iter to set parameters.
123 Junk global duration settings.
127 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
129 * minimum length second part broken tie
131 * en-,discouraged linebreaking:
132 - handle DISALLOW < penalty > FORCE
133 - discourage breaking of slurs
138 * fix variable define/lookup parser global<->paper
140 * fix title/instrument placements; see input/test/title.ly
142 * <\voiceone c4. \voicetwo c4>
144 * add full cello suites to web site (kom op, Maarten!)
146 * Rethink Time_description
147 * \cadenza , \meter, \grouping should all be \properties
152 - abbreviation-beam -> (measured/unmeasured) tremolo
154 * libtoolize flowerlib
158 * robustify Beam (in case of no stems, 32nd notes)
160 * decentralised spring factory
162 * move paper vars into engraver properties
164 * check for groff / troff/ nroff et
166 * more intelligent file searching
168 - make LilyPond fully relocatable
170 * use kpsepath to find all TeX dirs
175 - break-up heavily-nested score blocks
177 * disable spaces in TeX stuff
179 * handle ^C for tmp/file creation.
181 * dots & rest collisions.
189 * versioning for Feta
191 * the warning about the negative slur/tie length appears twice
194 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
197 * the bracket is ugly (wings are too parabolic, should be more circular)
199 * better hshift (dots, distance, head dependent)
201 * clefs (AG): The "8" should appear closer to the actual clef,
204 * give Items/Spanners access to unbroken originals
206 * scoping for properties?
209 \multi 2 < { \stemup .. } { \stemdown .. } >
213 this modifies \stem for the c2
215 * put errorlevel in Input class
219 * integrate midi-elts from mi2mu and lily?
221 * cautionary accidental
224 FMR: Free memory read:
225 * This is occurring while in:

264 * xdvi: PS in magnifying glass.
266 * GNU patch 2.1: hardcoded limit of 1024 to the linelength
268 * GNU diff 2.7: diff -rN does not see a new directory with empty file
270 * GNU patch 2.1: <must find simple example> if patch chokes on a
271 hunk, or on allegedly unsorted hunks in a diff, it may stop
272 without a trace of failure (create .rej file, print error or
273 dump core) and just ignore any further diffs.
277 f = fopen ("/dev/null", "r")
282 * GNU indent: handle C++
284 * GNU make: move hardcoded builtin rules to runtime ?

317 * use properties for:
324 - bartypes (get rid of derived Span_bar_engravers)
331 - optimal pagebreaking.
333 * Unicode support? -> man 7 unicode
336 - detect of 16/8 bit files

417 make ofi2 TeX, MusiXTex, Display PostScript, PostScript,
418 Ascii... interpreters. (difficult)
421 - Common Music Notation
422 - PostScript output (esp. Beams, Slurs, etc)
423 - Move all Score_elems, into libmutype.a
428 - Doc (C) stuff of sheet music

436 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
438 - doc on Rhythmic_grouping
439 - general shaving on Beam and Stem
441 - separate visual from rhythmic info even more
443 - endbeam req should be *after* the duration, so you can do
449 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
450 - set different line sizes / thicknesses
451 - beam stem showthrough, inter beam sizes (french vs german style)
454 - left/right note balls should be handled by Collision:
