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
14 * egcs-1.1 -O2 -finline-functions causes crash
17 * formatting of input stuff.
19 * use real RTTI iso access_Stuff.
21 * \notes{ a \< b \cr } vs \notes{ a \< b \! }
23 * if possible, it might be nice for a warning to appear if someone does
24 \translator with no name and without assigning it to an
31 * I see that \prallprall and \prallmordent are identical. I think this is a
32 mistake, that \prallprall should not have the vertical line.
33 This can be fixed by removing the line
34 draw_mordent(twidth-0.5toverlap);
35 from the definition of \prallprall in mf/feta-slag.mf (see below)
37 * fix singleStaffBracket
39 * repeat bars: need distance after ":|" and before "|:"
41 * The time signature warnings still remain, will be fixed later.
43 Summary of minor spelling irregularities:
44 - capitalization/use of underscores in property names
48 * repeat bars: need distance after ":|" and before "|:"
50 * \shape 1st dim skipped?
52 * fix marks/barnumbers/marginal notes
55 lbheel = \script { "bheel" 0 0 -1 0 0 }
56 rbheel = \script { "bheel" 0 0 1 0 0 }
57 lbtoe = \script { "btoe" 0 0 -1 0 0 }
58 rbtoe = \script { "btoe" 0 0 1 0 0 }

62 rftoe = \script { "ftoe" 0 0 1 0 0 }
66 portato= \script { "portato" 0 -1 0 1 0 }
70 * Align_element::padding ?
72 * uniformise property names.
74 * ydirection <-> yDirection
76 * typo checks on property names?
78 * make engraver hacking robust.
80 * use streambufs and iostream
81 to provide IO handling for TeX stream, mudela stream, data-file.
83 * seriously buffer TeX output (do profile of writing .5 mb TeX file.)
85 * strip EXEs before installing
87 * zip target for binary windows dist (JBR)
91 * revise documentation
95 * junking \skip req in lyrics
102 - mix engraver hacking with music ?
103 - \once\property KEY = VAL
104 - \addtranslator, \removetranslator
105 - junk ^ and _ for scripts
109 * install TeX stuff into tex/generic directory.
111 * /etc/profile.d support for RPM.
113 * percussion note heads
115 * mi2mu empty staffs.
119 * make GNU style webpages.
121 * There seems to be an install error in lilypond-1.0.0. Most of the
122 files in the "init" directory don't get installed in the
123 /usr/local/share/lilypond directory. The files installed are of
124 the form feta*.ly. In particular init.ly doesn't get installed.
125 I installed the files by hand and then the system seems to work.
127 * midi_instrument -> midiInstrument
129 * horizontal centering of dynamics
131 * \font\fontA=feta20.afm (.afm?)
135 * stable make/config stuff

146 * fix weird behaviour when .AFMs not found.
149 gs: Error: /undefined in draw_beam
152 * run texhash after installing .tex
154 * fix vertical alignment and stafflines
156 * GrandStaff needs more work -- I want a single word
157 `harpsichord' to the left of the grandstaff, not one on each
158 stave. (Organ staff -- with separate pedal -- but common
159 properties may be something to think about. Of course for
160 organ you want to be able to give stop indications on the way
161 through, so the \property Voice.Instrument would be a stop,
162 and \property GrandStaff.instrument would be PipeOrgan...)
164 * make Tie_req a "command" { <c g> ~ <c g> }
168 * revise the Score_priority_align_engraver concept. It sucks.
172 * make new VoiceOne, VoiceTwo, VoiceThree contexts with
173 ydirection and hshift preset
175 * *.yo: fix pod manpage layout legacy
177 * text-items clash with stems/beams

185 {\voicetwo cis,4 r r | r2. | r1 }> |
188 * try to use template<Type> iso MACRO(Type)
190 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
191 think about, analogous to pitch:
192 * { a4 a16 } c <-- duration of c?
193 * <a4 b8> c <-- duration of c?
197 * fix audio-items (don't use (input) requests, but copy data)
199 * junk My_lily_parser::abbrev_beam_type_i_
201 * make sure all ex's have a mudela-version
203 * do rest-collisions for Multi_measure_rests as well.
205 * split error/warning in error/warning/non_fatal_error
207 * add a Duration_convert member to Duration_iter to set parameters.
208 Junk global duration settings.
212 * clean up abbrev/plet/beam/abbrevbeam/duration mess in parser.
214 * minimum length second part broken tie
216 * en-,discouraged linebreaking:
217 - handle DISALLOW < penalty > FORCE
218 - discourage breaking of slurs
223 * fix variable define/lookup parser global<->paper
225 * fix title/instrument placements; see input/test/title.ly
227 * <\voiceone c4. \voicetwo c4>
229 * add full cello suites to web site (kom op, Maarten!)
231 * Rethink Time_description
232 * \cadenza , \meter, \grouping should all be \properties
237 - abbreviation-beam -> (measured/unmeasured) tremolo
238 - partial -> anacrouse

244 * robustify Beam (in case of no stems, 32nd notes)
246 * decentralised spring factory
248 * move paper vars into engraver properties
250 * check for groff / troff/ nroff et
252 * more intelligent file searching
254 - make LilyPond fully relocatable
256 * use kpsepath to find all TeX dirs
261 - break-up heavily-nested score blocks
263 * disable spaces in TeX stuff
265 * handle ^C for tmp/file creation.
267 * dots & rest collisions.
275 * versioning for Feta
277 * the warning about the negative slur/tie length appears twice
280 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
283 * the bracket is ugly (wings are too parabolic, should be more circular)
285 * better hshift (dots, distance, head dependent)
287 * clefs (AG): The "8" should appear closer to the actual clef,
290 * scoping for properties?
293 \multi 2 < { \stemup .. } { \stemdown .. } >
297 this modifies \stem for the c2
299 * put errorlevel in Input class
303 * integrate midi-elts from mi2mu and lily?
305 * cautionary accidental
308 FMR: Free memory read:
309 * This is occurring while in:

346 * gcc 2.8.1: see ice and RESIZE_ICE
348 * xdvi: PS in magnifying glass.
350 * GNU diff 2.7: diff -rN does not see a new directory with empty file
352 * GNU patch 2.1: <must find simple example> if patch chokes on a
353 hunk, or on allegedly unsorted hunks in a diff, it may stop
354 without a trace of failure (create .rej file, print error or
355 dump core) and just ignore any further diffs.
359 f = fopen ("/dev/null", "r")
364 * GNU indent: handle C++
366 * GNU make: move hardcoded builtin rules to runtime ?
369 - 'double-fix' mode: ignore identical fix, rather than suggest
370 to revert patch direction when (more or less? exactly) the same
376 - fix position of bar number

498 - Move all Score_elems, into libmutype.a
503 - Doc (C) stuff of sheet music
504 - a better format? SGML? TeX? Info?

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

597 * adaptive accidental spacing.
599 * handle EOF graciously in error messages.
