Features you cannot find in the doco as working, should be mentioned here. This is an assorted collection of stuff that will be done, might be done, or is an idea that I want to think about Most of the items are marked in the code as well, with full explanation. grep for TODO and ugh/ugr * Redo MIDI output to use Translators - remember more horizontal info than melodics: - tempo change - repeat - slurs - dynamics etc. * pushgroup/popgroup * strict separation between visual and auditive processing. * fix depcy/dept stuff in eg. Beam. * whole head on ledger line * piano staff * decent spacing * implement better breaking algorithm * update 20 pt table * decent TeX page layout * enter script priority * a Hands on tutorial [HKN] PROJECTS * grace notes - adapt for multiple font sizes. - make separate class for Grace_*_engravers (which is at Voice_gravs level) - move stem, beam, slur into baseclass to adapt for (fixed size) grace notes. * accidentals per Voice_group * Convert all ref/bib stuff into BibTeX. * Output class, handles : (smallish) - help text /(c) notice? - version line - warning /errors/progress - abort on error/warning; exit status - quiet/ignore-version options - logfile output * elaborate Staff_side baseclass: - scripts - text - slur start/end * Output an output format independent (ofi) typeset file; and make ofi2 TeX, MusixTex, PostScript, Ascii... interpreters. (difficult) - poor man's ascii output possible? - MusixTeX output possible? (would have to be done before break calc.) - NIFF ? - Common Music Notation - PostScript output (esp. Beams, Slurs, etc) - Move PScore, Items, Spanners etc. into libmutype.a * separate Score_elem settings in user-settable (properties .. ) and non-user-settable part. Maybe use something like X-resources: "Staff=oboe*dir: 0", "Staff=*.Voice_group=solo*dir: 1" * TeX spanners , use texbeam.cc as an example (smallish) - Glissando - trill - bracket * Rewrite Stem, Beam and Rhythmic_grouping (hairy) - [c8. c32 c32] - interbeam height - doc on Rhythmic_grouping - general shaving on Beam and Stem - use plet grouping - abbreviations [c2 c2]1/2 - separate visual from rhythmic info even more - beams over bars * Redo font support - rename mf fonts to avoid conflicts with musixtex - use own fonts/update musixtex fonts/find older (c)-less fonts - hack up mf sources for decent spacing info (and then read AFM/TFM directly, for text too) - use MF to generate rules. * lines: - Ledger lines, should be separate item: Ledger_lines, Ledger_lines - set different line sizes / thicknesses - stem down too far right - beam stem showthrough, inter beam sizes (french vs german style) * Collisions - bring Collision::do_pre_processing to haircutter - left/right note balls should be handled by Collision: < \multi 2; { \stem 1; } { } > * Keys: - merge key{item} & localkey{item}? - do conventional keys (C G A, F B E, a e fis, d as des, etc ), besides lists of flats/sharps, possibly via declaration - key transposition. - key undo: \key bes; .. . \key; should print natural - special key: \key 'b bes bis'; - spacing, national styles? PARSER * Duration -> Musical_duration, typedef Rational Duration? HKN buglist: tekst staat erg ver van notenbalken af BUGS * fix mysterious Flex malloc bug * should adjust stemlength for flag number. * lilypond - -> crash * standchen triool beam up/down * (where are the) gcc compile warnings on linux SEVERELY LACKING: * SPEED! * multibar rests * barnumbers, markers * abbreviations c4=16 INPUTLANGUAGE * c4 4 4 4 for c4 c4 c4 c4? * neatly (and readably) expressing concurrent voices * 4 ? * should have \require{package.ly} to read req'd packages. * Viola mode? @c c g e g for c g es g, @A c g e g for cis gis e gis * relative mode for pitch entering * bracket (bracketplets) * \duration 8; e*2/3 * configure pitch_byte * figured bass? * rest name configurable * Raw request syntax * subtime with Subtle_reqs PROJECTS * Do RTTI i.s.o. static_name(), name() and request-junk. SMALLISH PROJECTS * A range for context errors (eg. mark both { and }. ) * lyric in staff (sharpsharp in staff, text below) * fix Egler definitions ( see tex/eglerdefs.tex ) * replace Score_elem member access by get()/set() methods, to enable future embedded code. * --fast/--draft: leave out constraints * write Dynamic_line (to group dynamics horizontally) * write Rest_collision * use Real for y positions. * shared lib on Solaris too. * bugreport to doc++ devel: struct not in class hier; public virtual baseclasses * get rid of init_end; * cleanup lily-proto.hh and proto.hh * half-sharps, half-flats * adaptive accidental spacing. * unix style paths for LILYINCLUDE env * indentable stream as baseclass for TeX stream, lily stream, Dstream. * handle EOF graciously in error messages. * caching Item/spanner dimensions. * centered whole rest * caching breakpoints / saving them. * use dstream feature in mi2mu * qtor, btor, mtor-> tor( QUIET_ver ), tor( DEBUG_ver ), etc. - use tors feature in lily (?) * declare symtab * declare notenametab? * midi esp.: use I32 iso int where 32 bits are needed (or assumed...) * parshape * read from mmap directly: bugreport to flex developers-> yy_scan_buffer in C++.. * binsearch/hash for identifiers * stafftypes: voice names/ instrument names. * Decent TeX titledefs (\tempo, \metron, etc. ) * C meter iso 4/4, idem for alla breve, etc. * textspanner: center position * script-spacing * Brackets * use (char *) iso. String for communication between lexer and parser. * configure idealspacing: arithmetic spacing * LilyPond .deb. Other packaging methods? * detect -pipe DOC * Score_elem structure. * all errors * config of TeX macros * a test suite * hacking-HOWTO FUTURE * auxilliary file for caching info. * Reg_configure_request * slur parts as a script * mixed fontsizes * put scripts on bars * guitar chord * better beamslope calculation: QLP for beams? * Text_crescendo * clean solution for staffsize in items. * revise calcideal * volta IDEAS * check out CORBA for Score_elems? * derive PCol from Score_elem? More in Score_elems? Spacing? * scoping in Lexer: do general id- assignments in mudela. ID '=' EXPR; * create libmudela, or liblily_frontend * move MIDI stuff (including Quantization) to a ANSI C libmidi library. * use an embedded language: Python for: - Score_elems - Engraver - Translators - Complex mudela? * y -dims in internote? * merge Atom and Symbol? * merge common code of Item, Atom/Molecule * Spacing_request for manually adjusting spacing * caching breakpoints * #c <-> cis * breath marks * used fixedpoint arithmetic for min. energy. * default convert mudela-file.ly -> mudela-file.tex - rename {standchen,scsii-menuetto,...}.tex * stack scripts in chords: % fingering: footing: < a-4 c-2 g-1 > < c-\ltoe e-\lheel > * parameterised scripts for fingering and footing: % toe to bheel four to five % ^_u 4_5 % - % --|x-- --|x-- % --|--- --|--- % --|--- --|--- (where "to" is a tiny bow) * move towards incremental algorithms. * design meta-language like TeX and Metafont
