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.

34 * fix singleStaffBracket
36 * repeat bars: need distance after ":|" and before "|:"
38 - The time signature warnings still remain, will be fixed later.
40 * fix \n after proccing
42 Summary of minor spelling irregularities:
43 > capitalization/use of underscores in property names
44 > \lyric vs \notes \lyric vs \type Lyrics (\lyric should have an -s)
48 * repeat bars: need distance after ":|" and before "|:"
50 * \shape 1st dim skipped?

78 * Align_element::padding ?
80 * uniformise property names.
82 * ydirection <-> yDirection
84 * typo checks on property names?
88 * make engraver hacking robust.
90 * use streambufs and iostream
91 to provide IO handling for TeX stream, mudela stream, data-file.
93 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
95 * strip EXEs before installing
97 * zip target for binary windows dist (JBR)
101 * revise documentation
105 * junking \skip req in lyrics
108 - general plet mechanism.
110 \plet 2/3 { c8 c8 c8 }
114 Music: PLET int '/' int Music
116 - \type -> \context ?
120 - mix engraver hacking with music ?
121 - \once\property KEY = VAL
122 - \addtranslator, \removetranslator
123 - junk ^ and _ for scripts
127 * install TeX stuff into tex/generic directory.
129 * /etc/profile.d support for RPM.
131 * percussion note heads
133 * mi2mu empty staffs.
137 * make GNU style webpages.
139 * There seems to be an install error in lilypond-1.0.0. Most of the
140 files in the "init" directory don't get installed in the
141 /usr/local/share/lilypond directory. The files installed are of
142 the form feta*.ly. In particular init.ly doesn't get installed.
143 I installed the files by hand and then the system seems to work.
145 * midi_instrument -> midiInstrument
147 * horizontal centering of dynamics
149 * \font\fontA=feta20.afm (.afm?)
153 * stable make/config stuff
155 * stemup/stemdown; see test/updown.fly
156 - check examples; add \type Staff hither and thether
158 * $DEPENDENCIES_OUTPUT support
160 * use a fake-yodl.sh to mimick yodl when yodl is not installed
164 * fix weird behaviour when .AFMs not found.
167 gs: Error: /undefined in draw_beam
170 * run texhash after installing .tex
172 * fix vertical alignment and stafflines
174 * GrandStaff needs more work -- I want a single word
175 `harpsichord' to the left of the grandstaff, not one on each
176 stave. (Organ staff -- with separate pedal -- but common
177 properties may be something to think about. Of course for
178 organ you want to be able to give stop indications on the way
179 through, so the \property Voice.Instrument would be a stop,
180 and \property GrandStaff.instrument would be PipeOrgan...)
182 * make Tie_req a "command" { <c g> ~ <c g> }
186 * revise the Score_priority_align_engraver concept. It sucks.
190 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
191 ydirection and hshift preset
193 * *.yo: fix pod manpage layout legacy
195 * text-items clash with stems/beams
197 * --include, -I option for ly2dvi (pass on to lily)

202 <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 }
203 {\voicetwo cis,4 r r | r2. | r1 }> |
206 * try to use template<Type> iso MACRO(Type)
208 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
209 think about, analogous to pitch:
210 * { a4 a16 } c <-- duration of c?
211 * <a4 b8> c <-- duration of c?
215 * fix audio-items (don't use (input) requests, but copy data)
217 * junk My_lily_parser::abbrev_beam_type_i_
219 * make sure all ex's have a mudela-version
221 * do rest-collisions for Multi_measure_rests as well.
223 * split error/warning in error/warning/non_fatal_error
225 * add a Duration_convert member to Duration_iter to set parameters.
226 Junk global duration settings.
230 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
232 * minimum length second part broken tie
234 * en-,discouraged linebreaking:
235 - handle DISALLOW < penalty > FORCE
236 - discourage breaking of slurs
241 * fix variable define/lookup parser global<->paper
243 * fix title/instrument placements; see input/test/title.ly
245 * <\voiceone c4. \voicetwo c4>
247 * add full cello suites to web site (kom op, Maarten!)
249 * Rethink Time_description
250 * \cadenza , \meter, \grouping should all be \properties
255 - abbreviation-beam -> (measured/unmeasured) tremolo
256 - partial -> anacrouse
258 * libtoolize flowerlib
262 * robustify Beam (in case of no stems, 32nd notes)
264 * decentralised spring factory
266 * move paper vars into engraver properties
268 * check for groff / troff/ nroff et
270 * more intelligent file searching
272 - make LilyPond fully relocatable
274 * use kpsepath to find all TeX dirs
279 - break-up heavily-nested score blocks
281 * disable spaces in TeX stuff
283 * handle ^C for tmp/file creation.
285 * dots & rest collisions.
293 * versioning for Feta
295 * the warning about the negative slur/tie length appears twice
298 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
301 * the bracket is ugly (wings are too parabolic, should be more circular)
303 * better hshift (dots, distance, head dependent)
305 * clefs (AG): The "8" should appear closer to the actual clef,
308 * scoping for properties?
311 \multi 2 < { \stemup .. } { \stemdown .. } >
315 this modifies \stem for the c2
317 * put errorlevel in Input class
321 * integrate midi-elts from mi2mu and lily?
323 * cautionary accidental
326 FMR: Free memory read:
327 * This is occurring while in:

364 * gcc 2.8.1: see ice and RESIZE_ICE
366 * xdvi: PS in magnifying glass.
368 * GNU diff 2.7: diff -rN does not see a new directory with empty file
370 * GNU patch 2.1: <must find simple example> if patch chokes on a
371 hunk, or on allegedly unsorted hunks in a diff, it may stop
372 without a trace of failure (create .rej file, print error or
373 dump core) and just ignore any further diffs.
377 f = fopen ("/dev/null", "r")
382 * GNU indent: handle C++
384 * GNU make: move hardcoded builtin rules to runtime ?
387 - 'double-fix' mode: ignore identical fix, rather than suggest
388 to revert patch direction when (more or less? exactly) the same
394 - fix position of bar number
395 - stack scripts in chords:
396 % fingering: footing:

421 - bartypes (get rid of derived Span_bar_engravers)
426 - optimal pagebreaking.
428 * Unicode support? -> man 7 unicode
431 - detect of 16/8 bit files

483 (which is at Voice_gravs level)
484 - make encapsulated spacing problems.
486 * accidentals per Voice_group

515 - PostScript output (esp. Beams, Slurs, etc)
516 - Move all Score_elems, into libmutype.a
521 - Doc (C) stuff of sheet music
522 - a better format? SGML? TeX? Info?
525 * more spanners (smallish)
529 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
531 - doc on Rhythmic_grouping
532 - general shaving on Beam and Stem

536 - endbeam req should be *after* the duration, so you can do
542 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
543 - set different line sizes / thicknesses
544 - beam stem showthrough, inter beam sizes (french vs german style)
547 - left/right note balls should be handled by Collision:
548 < \multi 2; { \stem 1; <b c> } { <f as b> } >
551 - merge key{item} & localkey{item}?
553 - spacing, national styles?
556 - redo Notehead to allow digits as heads

616 * adaptive accidental spacing.
618 * handle EOF graciously in error messages.
620 * centered whole rest
