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 * add ex-dimension to feta-params.
13 * strip EXEs before installing
17 * fix plain tex footer line.
19 * portable libs for flowerlib/lilylib
21 * install TeX stuff into tex/generic directory.
23 * preformatted .info stuff.
25 * percussion note heads
31 * make separate translation property list.
33 * make GNU style webpages.
35 * There seems to be an install error in lilypond-1.0.0. Most of the
36 files in the "init" directory don't get installed in the
37 /usr/local/share/lilypond directory. The files installed are of
38 the form feta*.ly. In particular init.ly doesn't get installed.
39 I installed the files by hand and then the system seems to work.
41 * midi_instrument -> midiInstrument
43 * horizontal centering of dynamics
45 * \font\fontA=feta20.afm (.afm?)
49 * stable make/config stuff
51 * stemup/stemdown; see test/updown.fly
52 - check examples; add \type Staff hither and thether
54 * $DEPENDENCIES_OUTPUT support
56 * use a fake-yodl.sh to mimick yodl when yodl is not installed
60 * fix weird behaviour when .AFMs not found.
63 gs: Error: /undefined in draw_beam
66 * run texhash after installing .tex
68 * fix vertical alignment and stafflines
70 *GrandStaff needs more work -- I want a single word `harpsichord' to the
71 left of the grandstaff, not one on each stave.
72 (Organ staff -- with separate pedal -- but common properties may be
73 something to think about. Of course for organ you want to be able
74 to give stop indications on the way through, so the \property
75 Voice.Instrument would be a stop, and \property
76 GrandStaff.instrument would be PipeOrgan...)
79 * make Tie_req a "command" { <c g> ~ <c g> }
83 * mix engraver hacking with music ?
85 * revise the Score_priority_align_engraver concept. It sucks.
89 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
90 ydirection and hshift preset
93 - /usr/bin/make-patch?
95 * *.yo: fix pod manpage layout legacy
97 * text-items clash with stems/beams
99 * --include, -I option for ly2dvi (pass on to lily)
101 * fix placement of beam-less abbrev
104 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
105 {\voicetwo cis,4 r r | r2. | r1 }> |
108 * try to use template<Type> iso MACRO(Type)
110 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
111 think about, analogous to pitch:
112 * { a4 a16 } c <-- duration of c?
113 * <a4 b8> c <-- duration of c?
117 * fix audio-items (don't use (input) requests, but copy data)
119 * junk My_lily_parser::abbrev_beam_type_i_
121 * make sure all ex's have a mudela-version
123 * do rest-collisions for Multi_measure_rests as well.
125 * split error/warning in error/warning/non_fatal_error
127 * add a Duration_convert member to Duration_iter to set parameters.
128 Junk global duration settings.
132 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
134 * minimum length second part broken tie
136 * en-,discouraged linebreaking:
137 - handle DISALLOW < penalty > FORCE
138 - discourage breaking of slurs
143 * fix variable define/lookup parser global<->paper
145 * fix title/instrument placements; see input/test/title.ly
147 * <\voiceone c4. \voicetwo c4>
149 * add full cello suites to web site (kom op, Maarten!)
151 * Rethink Time_description
152 * \cadenza , \meter, \grouping should all be \properties
157 - abbreviation-beam -> (measured/unmeasured) tremolo
159 * libtoolize flowerlib
163 * robustify Beam (in case of no stems, 32nd notes)
165 * decentralised spring factory
167 * move paper vars into engraver properties
169 * check for groff / troff/ nroff et
171 * more intelligent file searching
173 - make LilyPond fully relocatable
175 * use kpsepath to find all TeX dirs
180 - break-up heavily-nested score blocks
182 * disable spaces in TeX stuff
184 * handle ^C for tmp/file creation.
186 * dots & rest collisions.
194 * versioning for Feta
196 * the warning about the negative slur/tie length appears twice
199 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
202 * the bracket is ugly (wings are too parabolic, should be more circular)
204 * better hshift (dots, distance, head dependent)
206 * clefs (AG): The "8" should appear closer to the actual clef,
209 * give Items/Spanners access to unbroken originals
211 * scoping for properties?
214 \multi 2 < { \stemup .. } { \stemdown .. } >
218 this modifies \stem for the c2
220 * put errorlevel in Input class
224 * integrate midi-elts from mi2mu and lily?
226 * cautionary accidental
229 FMR: Free memory read:
230 * This is occurring while in:

258 TeX output to score-bar-scripts.tex...
263 * redhat (v?) graphical install bomb-out?

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

322 * use properties for:
329 - bartypes (get rid of derived Span_bar_engravers)
336 - optimal pagebreaking.
338 * Unicode support? -> man 7 unicode
341 - detect of 16/8 bit files

422 make ofi2 TeX, MusiXTex, Display PostScript, PostScript,
423 Ascii... interpreters. (difficult)
426 - Common Music Notation
427 - PostScript output (esp. Beams, Slurs, etc)
428 - Move all Score_elems, into libmutype.a
433 - Doc (C) stuff of sheet music
434 - a better format? SGML? TeX? Info?

441 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
443 - doc on Rhythmic_grouping
444 - general shaving on Beam and Stem
446 - separate visual from rhythmic info even more
448 - endbeam req should be *after* the duration, so you can do
454 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
455 - set different line sizes / thicknesses
456 - beam stem showthrough, inter beam sizes (french vs german style)
459 - left/right note balls should be handled by Collision:
460 < \multi 2; { \stem 1; <b c> } { <f as b> } >
463 - merge key{item} & localkey{item}?
465 - spacing, national styles?

511 * fix confusing naming in Engraver vs Engraver_group_engraver (context)
513 * progress when creating MIDI elts.
515 * A range for context errors (eg. mark both { and }. )
517 * lyric in staff (sharpsharp in staff, text below)
