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 * use streambufs to provide IO handling for TeX stream, mudela stream,
13 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
15 * strip EXEs before installing
17 * zip target for binary windows dist (JBR)
19 * repeat bars: need distance after ":|" and before "|:"
21 * doco should not depend on a4
25 * fix plain tex footer line.
27 * install TeX stuff into tex/generic directory.
29 * preformatted .info stuff.
31 * percussion note heads
37 * make separate translation property list.
39 * make GNU style webpages.
41 * There seems to be an install error in lilypond-1.0.0. Most of the
42 files in the "init" directory don't get installed in the
43 /usr/local/share/lilypond directory. The files installed are of
44 the form feta*.ly. In particular init.ly doesn't get installed.
45 I installed the files by hand and then the system seems to work.
47 * midi_instrument -> midiInstrument
49 * horizontal centering of dynamics
51 * \font\fontA=feta20.afm (.afm?)
55 * stable make/config stuff
57 * stemup/stemdown; see test/updown.fly
58 - check examples; add \type Staff hither and thether
60 * $DEPENDENCIES_OUTPUT support
62 * use a fake-yodl.sh to mimick yodl when yodl is not installed
66 * fix weird behaviour when .AFMs not found.
69 gs: Error: /undefined in draw_beam
72 * run texhash after installing .tex
74 * fix vertical alignment and stafflines
76 *GrandStaff needs more work -- I want a single word `harpsichord' to the
77 left of the grandstaff, not one on each stave.
78 (Organ staff -- with separate pedal -- but common properties may be
79 something to think about. Of course for organ you want to be able
80 to give stop indications on the way through, so the \property
81 Voice.Instrument would be a stop, and \property
82 GrandStaff.instrument would be PipeOrgan...)
85 * make Tie_req a "command" { <c g> ~ <c g> }
89 * mix engraver hacking with music ?
91 * revise the Score_priority_align_engraver concept. It sucks.
95 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
96 ydirection and hshift preset
98 * *.yo: fix pod manpage layout legacy
100 * text-items clash with stems/beams
102 * --include, -I option for ly2dvi (pass on to lily)
104 * fix placement of beam-less abbrev
107 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
108 {\voicetwo cis,4 r r | r2. | r1 }> |
111 * try to use template<Type> iso MACRO(Type)
113 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
114 think about, analogous to pitch:
115 * { a4 a16 } c <-- duration of c?
116 * <a4 b8> c <-- duration of c?
120 * fix audio-items (don't use (input) requests, but copy data)
122 * junk My_lily_parser::abbrev_beam_type_i_
124 * make sure all ex's have a mudela-version
126 * do rest-collisions for Multi_measure_rests as well.
128 * split error/warning in error/warning/non_fatal_error
130 * add a Duration_convert member to Duration_iter to set parameters.
131 Junk global duration settings.
135 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
137 * minimum length second part broken tie
139 * en-,discouraged linebreaking:
140 - handle DISALLOW < penalty > FORCE
141 - discourage breaking of slurs
146 * fix variable define/lookup parser global<->paper
148 * fix title/instrument placements; see input/test/title.ly
150 * <\voiceone c4. \voicetwo c4>
152 * add full cello suites to web site (kom op, Maarten!)
154 * Rethink Time_description
155 * \cadenza , \meter, \grouping should all be \properties
160 - abbreviation-beam -> (measured/unmeasured) tremolo
161 - partial -> anacrouse
163 * libtoolize flowerlib
167 * robustify Beam (in case of no stems, 32nd notes)
169 * decentralised spring factory
171 * move paper vars into engraver properties
173 * check for groff / troff/ nroff et
175 * more intelligent file searching
177 - make LilyPond fully relocatable
179 * use kpsepath to find all TeX dirs
184 - break-up heavily-nested score blocks
186 * disable spaces in TeX stuff
188 * handle ^C for tmp/file creation.
190 * dots & rest collisions.
198 * versioning for Feta
200 * the warning about the negative slur/tie length appears twice
203 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
206 * the bracket is ugly (wings are too parabolic, should be more circular)
208 * better hshift (dots, distance, head dependent)
210 * clefs (AG): The "8" should appear closer to the actual clef,
213 * scoping for properties?
216 \multi 2 < { \stemup .. } { \stemdown .. } >
220 this modifies \stem for the c2
222 * put errorlevel in Input class
226 * integrate midi-elts from mi2mu and lily?
228 * cautionary accidental
231 FMR: Free memory read:
232 * This is occurring while in:

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

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

424 make ofi2 TeX, MusiXTex, Display PostScript, PostScript,
425 Ascii... interpreters. (difficult)
428 - Common Music Notation
429 - PostScript output (esp. Beams, Slurs, etc)
430 - Move all Score_elems, into libmutype.a
435 - Doc (C) stuff of sheet music
436 - a better format? SGML? TeX? Info?

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

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