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.

25 identifier. possible, it might be nice for a warning to appear if

34 * I see that \prallprall and \prallmordent are identical. I think this is a
35 mistake, that \prallprall should not have the vertical line.
36 This can be fixex by removing the line
37 > draw_mordent(twidth-0.5toverlap);
38 from the definition of \prallprall in mf/feta-slag.mf (see below)
40 * fix singleStaffBracket
42 * repeat bars: need distance after ":|" and before "|:"
44 - The time signature warnings still remain, will be fixed later.
46 * fix \n after proccing
48 Summary of minor spelling irregularities:
49 > capitalization/use of underscores in property names
50 > \lyric vs \notes \lyric vs \type Lyrics (\lyric should have an -s)
54 * repeat bars: need distance after ":|" and before "|:"
56 * \shape 1st dim skipped?
58 * fix marks/barnumbers/marginal notes

84 * Align_element::padding ?
86 * uniformise property names.
88 * ydirection <-> yDirection
90 * typo checks on property names?
94 * make engraver hacking robust.
96 * use streambufs and iostream
97 to provide IO handling for TeX stream, mudela stream, data-file.
99 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
101 * strip EXEs before installing
103 * zip target for binary windows dist (JBR)
105 * text continuationss
107 * revise documentation
111 * junking \skip req in lyrics
114 - general plet mechanism.
116 \plet 2/3 { c8 c8 c8 }
120 Music: PLET int '/' int Music
122 - \type -> \context ?
126 - mix engraver hacking with music ?
127 - \once\property KEY = VAL
128 - \addtranslator, \removetranslator
129 - junk ^ and _ for scripts
133 * install TeX stuff into tex/generic directory.
135 * /etc/profile.d support for RPM.
137 * percussion note heads
139 * mi2mu empty staffs.
143 * make GNU style webpages.
145 * There seems to be an install error in lilypond-1.0.0. Most of the
146 files in the "init" directory don't get installed in the
147 /usr/local/share/lilypond directory. The files installed are of
148 the form feta*.ly. In particular init.ly doesn't get installed.
149 I installed the files by hand and then the system seems to work.
151 * midi_instrument -> midiInstrument
153 * horizontal centering of dynamics
155 * \font\fontA=feta20.afm (.afm?)
159 * stable make/config stuff

164 * $DEPENDENCIES_OUTPUT support
166 * use a fake-yodl.sh to mimick yodl when yodl is not installed
170 * fix weird behaviour when .AFMs not found.
173 gs: Error: /undefined in draw_beam
176 * run texhash after installing .tex
178 * fix vertical alignment and stafflines
180 * GrandStaff needs more work -- I want a single word
181 `harpsichord' to the left of the grandstaff, not one on each
182 stave. (Organ staff -- with separate pedal -- but common
183 properties may be something to think about. Of course for
184 organ you want to be able to give stop indications on the way
185 through, so the \property Voice.Instrument would be a stop,
186 and \property GrandStaff.instrument would be PipeOrgan...)
188 * make Tie_req a "command" { <c g> ~ <c g> }
192 * revise the Score_priority_align_engraver concept. It sucks.
196 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
197 ydirection and hshift preset
199 * *.yo: fix pod manpage layout legacy
201 * text-items clash with stems/beams

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

370 * gcc 2.8.1: see ice and RESIZE_ICE
372 * xdvi: PS in magnifying glass.
374 * GNU diff 2.7: diff -rN does not see a new directory with empty file
376 * GNU patch 2.1: <must find simple example> if patch chokes on a
377 hunk, or on allegedly unsorted hunks in a diff, it may stop
378 without a trace of failure (create .rej file, print error or
379 dump core) and just ignore any further diffs.
383 f = fopen ("/dev/null", "r")
388 * GNU indent: handle C++
390 * GNU make: move hardcoded builtin rules to runtime ?

394 to revert patch direction when (more or less? exactly) the same
400 - fix position of bar number
401 - stack scripts in chords:

522 - Move all Score_elems, into libmutype.a
527 - Doc (C) stuff of sheet music
528 - a better format? SGML? TeX? Info?
531 * more spanners (smallish)
535 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
537 - doc on Rhythmic_grouping
538 - general shaving on Beam and Stem

542 - endbeam req should be *after* the duration, so you can do
548 - Ledger lines, should be separate item: Ledger_lines, Ledger_lines
549 - set different line sizes / thicknesses
550 - beam stem showthrough, inter beam sizes (french vs german style)
553 - left/right note balls should be handled by Collision:
554 < \multi 2; { \stem 1; <b c> } { <f as b> } >
557 - merge key{item} & localkey{item}?
559 - spacing, national styles?

622 * adaptive accidental spacing.
624 * handle EOF graciously in error messages.
626 * centered whole rest
