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
9 * fix plain tex footer line.
11 * portable libs for flowerlib/lilylib
13 * install TeX stuff into tex/generic directory.
16 * make GNU style webpages.
18 * There seems to be an install error in lilypond-1.0.0. Most of the
19 files in the "init" directory don't get installed in the
20 /usr/local/share/lilypond directory. The files installed are of
21 the form feta*.ly. In particular init.ly doesn't get installed.
22 I installed the files by hand and then the system seems to work.
24 * I things it's more than appropriate for an GNU project to ship Info
25 files (and manpages) with the source package. The "Standard" tells to
26 do so (ftp://ftp.gnu.org/pub/gnu/standards/standards.text):
29 * a `make check' target (without installing stuff!)
31 * midi_instrument -> midiInstrument
33 * horizontal centering of dynamics
35 * \font\fontA=feta20.afm (.afm?)
39 * stable make/config stuff
41 * stemup/stemdown; see test/updown.fly
42 - check examples; add \type Staff hither and thether
44 * $DEPENDENCIES_OUTPUT support
46 * use a fake-yodl.sh to mimick yodl when yodl is not installed
50 * fix weird behaviour when .AFMs not found.
53 gs: Error: /undefined in draw_beam
56 * run texhash after installing .tex
58 * fix vertical alignment and stafflines
60 *GrandStaff needs more work -- I want a single word `harpsichord' to the
61 left of the grandstaff, not one on each stave.
62 (Organ staff -- with separate pedal -- but common properties may be
63 something to think about. Of course for organ you want to be able
64 to give stop indications on the way through, so the \property
65 Voice.Instrument would be a stop, and \property
66 GrandStaff.instrument would be PipeOrgan...)
69 * make Tie_req a "command" { <c g> ~ <c g> }
73 * mix engraver hacking with music ?
75 * revise the Score_priority_align_engraver concept. It sucks.
79 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
80 ydirection and hshift preset
83 - /usr/bin/make-patch?
85 * *.yo: fix pod manpage layout legacy
87 * text-items clash with stems/beams
89 * --include, -I option for ly2dvi (pass on to lily)
91 * fix placement of beam-less abbrev
94 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
95 {\voicetwo cis,4 r r | r2. | r1 }> |
98 * try to use template<Type> iso MACRO(Type)
100 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
101 think about, analogous to pitch:
102 * { a4 a16 } c <-- duration of c?
103 * <a4 b8> c <-- duration of c?
107 * fix audio-items (don't use (input) requests, but copy data)
109 * junk My_lily_parser::abbrev_beam_type_i_
111 * make sure all ex's have a mudela-version
113 * do rest-collisions for Multi_measure_rests as well.
115 * split error/warning in error/warning/non_fatal_error
117 * add a Duration_convert member to Duration_iter to set parameters.
118 Junk global duration settings.
122 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
124 * minimum length second part broken tie
126 * en-,discouraged linebreaking:
127 - handle DISALLOW < penalty > FORCE
128 - discourage breaking of slurs
133 * fix variable define/lookup parser global<->paper
135 * fix title/instrument placements; see input/test/title.ly
137 * <\voiceone c4. \voicetwo c4>
139 * add full cello suites to web site (kom op, Maarten!)
141 * Rethink Time_description
142 * \cadenza , \meter, \grouping should all be \properties
147 - abbreviation-beam -> (measured/unmeasured) tremolo
149 * libtoolize flowerlib
153 * robustify Beam (in case of no stems, 32nd notes)
155 * decentralised spring factory
157 * move paper vars into engraver properties
159 * check for groff / troff/ nroff et
161 * more intelligent file searching
163 - make LilyPond fully relocatable
165 * use kpsepath to find all TeX dirs
170 - break-up heavily-nested score blocks
172 * disable spaces in TeX stuff
174 * handle ^C for tmp/file creation.
176 * dots & rest collisions.
184 * versioning for Feta
186 * the warning about the negative slur/tie length appears twice
189 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
192 * the bracket is ugly (wings are too parabolic, should be more circular)
194 * better hshift (dots, distance, head dependent)
196 * clefs (AG): The "8" should appear closer to the actual clef,
199 * give Items/Spanners access to unbroken originals
201 * scoping for properties?
204 \multi 2 < { \stemup .. } { \stemdown .. } >
208 this modifies \stem for the c2
210 * put errorlevel in Input class
214 * integrate midi-elts from mi2mu and lily?
216 * cautionary accidental
219 FMR: Free memory read:
220 * This is occurring while in:

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

312 * use properties for:
319 - bartypes (get rid of derived Span_bar_engravers)
326 - optimal pagebreaking.
328 * Unicode support? -> man 7 unicode
331 - detect of 16/8 bit files

412 make ofi2 TeX, MusiXTex, Display PostScript, PostScript,
413 Ascii... interpreters. (difficult)
416 - Common Music Notation
417 - PostScript output (esp. Beams, Slurs, etc)
418 - Move all Score_elems, into libmutype.a
423 - Doc (C) stuff of sheet music
424 - a better format? SGML? TeX? Info?

431 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
433 - doc on Rhythmic_grouping
434 - general shaving on Beam and Stem
436 - separate visual from rhythmic info even more
438 - endbeam req should be *after* the duration, so you can do
444 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
445 - set different line sizes / thicknesses
446 - beam stem showthrough, inter beam sizes (french vs german style)
449 - left/right note balls should be handled by Collision:
450 < \multi 2; { \stem 1; <b c> } { <f as b> } >

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