-*-outline-layout:(2 (-1 -1 0 :) 0);outline-stylish-prefixes:nil -*- * GNU LilyPond TODO Features you cannot find in the documentation 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 we want to think about. Most of the items are marked in the code as well Grep -i for TODO, FIXME and ugh/ugr/urg. .* TODO . * use hash tabs iso. alist_ for elt property? . * fix tremolos. . * ROADMAP file. . * change ) c4 to c4-) . * internationalize GUILE msgs. . * unbroken marks. . * write smobifying howto. . * \property autoBeamOverRest (boolean). Don't stop for rests when autobeaming. ? . * put property test files in refman. . * fix slurdotted! . * alignment within @itemize . * interstaff stems . * junk dstream output. . * Change website to be index to documentation. . * \grace { c d } c1 in midi . * \prop slurdir in grace notes . * \eltproperty "=Context" "Elt_name" "prop-name" #value . * script columns . * Must stop before this music ends: verse=\lyrics { . * input/test/grace.sly: wierd big spacing on grace notes . * TODO^2: . * make a TODO.texi, like http://www.gnu.org/software/guile/ideas.html . * make this file understandable for 3rd parties. . * \accepts -> \acceptedby . * context in embedded SCM errors. . * acc at tied note after linebreak. . * fontSize for time sigs and beams. . * fix font-naming and selecting . * add context information to warnings Paper: waarschuwing: Kan niet beide uiteinden van bindingsboog vinden MIDI: pa.ly:33:23: waarschuwing: Schroot verzoek: `Span_req': g' a4 bes8 \grace f8( )es16 d es8 r c | . * chord tonic: placement of accidental C#, Cb (from scm and C++) . * note head on stem err msg in dutch. . * why need to run -C mf twice? . * here's no difference at all in output. When either is jacked up to 7.0, everything works and matches up; when either is set just a bit above the default 5.0 (5.4 is what I was hoping to use), stems miss note heads. So it's some sort of a numerical (truncation/roundoff) problem. John . * fix #'margin-shape; setting indent to 0 with \shape fails . * Fixed size staff/system heights; . * ly2dvi : don't repeat opus if same. . * hara kiri _8 clef. . * junk -M ? . * mudela-book doco . * bracket pdf hack . * Mondrup: - if I change the property minVerticalAlign in a multi staff score with lyrics the change affects the lyrics too. I would like the change to _only_ affect staves. - I would like to be able to influence the sloping of xtuplet brackets - after the leading measure in the above mentioned score I want a double bar line fully drawn across the staves and after that keep to the ChoirStaff bar line types in the rest of the scores . * Write script that uses --find-old-relative to do auto relativization. .* Cleanups needed . * \$ and $ identifier syntax in examples. . * Key_engraver, Local_key_item . * Think of comprehensive solution for "if (grace_b == self_grace_b_)" . * String[String.length] doesn't trap. . * Rhythmic_column and interaction stem/rhythmic_column/note_head/dots. . * clef engraver . * parser . * Lookup::text -> needs to be TeX independent. . * junk Music_iterator::first_b_ .* ACCIDENTALS . * half-sharps, half-flats . * adaptive accidental spacing. . * accidentals closer to note head .* BEAMS . * [c8. c16 c16 c16] in 6/8 timesig. . * Rewrite Stem, Beam (hairy) . * beams over barlines . * Rests and beams don't work too well together. Example: [ r8 g''16 des'] [r8 c16 a] . * autoBeamMelisma: if I explicitly beam notes in a staff with auto beaming disabled I would like to have these beams also to be melismatic. . * The stemLength property should affect also beamed stems. . * staffside spanner (crescendo!) along with staffswitch. . * * auto melismaBusy for beams. . * \context Staff < > {\voiceone''4. r8} > \voicetwo c,4 r4} > > . * \time forces keysig? .* STUFF . * We need feta-din*.mf files for more sizes than 10. . * align left edge of broken tuplet-spanner (have a test case?) . * fix dynamics decently, ie. use kerning & ligatures. . * key restorations & repeats . * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?) . *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and ends on a pair of grace notes. Standard practice is to mark this with a slur starting on the main note and ending on the grace note, so a singer knows where to break the words. In bar 27, there's a crescendo that's supposed to start at the start of the grace notes and extend to the note after the grace notes. . * 4. Lyrics and grace sections don't go too well together. The words are aligned with the main note, not the start of the grace note. This is usually wrong, but is sometimes right. . * tie-direction . * rhythmic staff & accidentals. . * use melismaBusy in Lyric context to typeset melismata correctly. . * ly2dvi/lilypond logfile. . * hang Item on Spanner . * do --safe for PS output? . * msgfmt -o check? . * collision of lyrics with span_bars. See star-spangled. . * It is impossible to typeset two textual scripts that are stacked on top of each other and avoids note collisions and at the same time are typeset with different textStyle. I tried to move around the text_engraver and other engravers between Voice and Thread but the granularity is not fine enough, the scripts have to share the same engraver in order to be get correct vertical position but than they cannot have different style. In my opinion, all scripts that share the same staff, should be stacked vertically, avoiding collisions with the notes in all voices. . * Matanya's tips: . * don't shorten stems/staffs closer to each other. . * to space the staffs/staffgroups contained in the score. . * heavier beams? . * Abstraction for engravers: . * make "in-between" engraver (Tie) . * make wide_spanner_engraver (line_group_spanner, staff_symbol) . * store req -> element, element -> element causes for warnings . * My wish list for lyrics. I dream of a time when I will have enough time to become familiar enough with the source code to be able to implement some of these myself, but I don't know when that will be, so I thought I'd "publish" my suggestions in case someone else is in a position to give them some priority. Otherwise, perhaps they could go on the todo list? If any of these are already implemented, please let me what the syntax is to use them! 1. Stanza numbering. Numbering at the beginning of a song with the number set to the left of the first note. It would also be nice (but not as important) to be able to have some form of automatic numbering at the beginning of each new line. This would make it easier to follow songs with a large number of stanzas. 3. Notes centred above/below lyrics rather than left-aligned. 4. It would be very nice to be able to build some kind of phrasing into the lyrics of hymns, etc, so that the first words of a phrase are left aligned with each other, the last words are right aligned, and the words in between are centred. 5. In a song, with (say) four stanzas and a chorus, it would be nice to be able to vertically align the chorus midway between the staves. 6. It would be nice to be able to put vertical brackets either side of a repeated section with different words for each repeat. . * Give # lines in linebreaking. . * arrows on slurs. . * rewrite context defs using Scheme . * junk TeX specifics from internal code. . * \selectmusic to cut pieces from music. . * formatting of input stuff. . * deps for ly2dvi . * TODO: merge atom & molecule; make tree from molecule. . * Align_element::padding ? . * use streambufs and iostream to provide IO handling for TeX stream, mudela stream, data-file. . * seriously buffer TeX output (do profile of writing .5 mb TeX file.) . * fix partial measures in meaningful way. . * uniformise recent feta contributions. . * bigger and fatter 4/4 C . * relative mode for midi2ly . * junking \skip req in lyrics . * midi2ly empty staffs. . * use Fourier transformation for rhythmic quantisation. . * horizontal centering of dynamics . * $DEPENDENCIES_OUTPUT support . * turn slope-damping on/off . * sort out directory stuff. . * --prefix option? . * -I option per filetype? . * kpathsea? . * declaring Performers . * text-items clash with stems/beams . * --include, -I option for ly2dvi (pass on to lily) . * fix placement of beam-less abbrev . * \meter 3/4; <{\voiceone cis4. cis8 cis4 | cis4 cis cis | r1 } {\voicetwo cis,4 r r | r2. | r1 }> | } . * Musical_pitch (analogous to Duration and Rhythmic_req) think about, analogous to pitch: * { a4 a16 } c <-- duration of c? * < a4 b8 > c <-- duration of c? . * \tempo 4. = 90; . * do rest-collisions for Multi_measure_rests as well. . * split error/warning in error/warning/non_fatal_error . * discourage breaking of slurs . * fix variable define/lookup parser global<->paper . * fix title/instrument placements; see input/test/title.ly . * <\voiceone c4. \voicetwo c4> . * I'd like to change the \repetitions command to Jan's suggested syntax: \repeat "repeatsymbol" 2 {...}, but I'm not sure that I understand the implementation of repeats well enough. . * add mudela-book-doc source to webstie. . * fix singleStaffBracket . * rename . * partial -> anacrouse . * move paper vars into engraver properties . * add new glyphs to font.ly . * more intelligent file searching . * disable spaces in TeX stuff . * handle ^C for tmp/file creation. . * make LilyPond RPM fully relocatable . * better hshift (dots, distance, head dependent) . * didot / big point. . * clefs (AG): The "8" should appear closer to the actual clef, touching it. . * put errorlevel in Input class . * junk nesting slurs .* FONT . * the bracket is ugly (wings are too parabolic, should be more circular) . * versioning for Feta . * rewrite dynamic signs.
