-* 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?
-. * unhardcode stuff in bezier-bow: all sizes other than 20pt are
- broken
-. * use ports iso. iostream.
-. * hard constraints for broken slurs to.
-. * Staff_margin_engraver placement is broken for Staff.instr(ument)
-. * Bracket/brace placement and stacking is broken
-. * Lattermann:
-
- 2. There dynamic markings of the cello part are set in roman (maybe
- because of pizz. and arco in roman?)
-
- 4. Bar 41/42, violins: the ties should be the same direction, pref.
- down in bar 42.
- -- dir of broken ties
-
- 7. This is a bug: there's a colon in the middle of the two harmonium
- staves
-
- 12. bars 82 to 84 and 88: the ties of upper harmonium should all bend down.
- -- stemdown ~ stemup and at linebreak
-
- 15. bar 89, harmonium, the ties coming from the previous line look strangely
- asymmetric.
-
-
-. * Mondrup:
-
-- In some cases I don't get the large textsize within note examples I request.
-Consider for example the entry 'c clef', where \property Lyrics.textStyle = "large"
-used to give that result. It doesn't now. The large text sizes DO work in other cases,
-for example in the entry 'chord' (\property Voice.textStyle = "large"). To me it looks
-like the property Voice.textStyle is working while Lyrics.textStyle isn't. Consider
-for example the entry 'functional harmony' which has the same problem as 'chord'
-
-- I don't get full size clef changes upon issuing \property Voice.clefStyle =
-"fullSizeChanges", see for example the entry 'c clef'.
-
-- In the entry 'brace' the second note example using \context StaffGroup gets the
-staff bracket offset to the left page margin !! while the first note example behaves
-normally.
-
-- <p><img> in mudela-book
-. * mats
-
-If textStyle is set (in the \paper section), this setting
-applies also to dynamics.
-
-Also, the marginScriptPadding should be set by default to give
-a nice layout, but that's already been reported on the list.
-
-- What happened to the StaffGroup brackets?
- Try input/test/orchestscore.ly which worked fine in pl 27.
-
-- Why do I get bar numbers on every bar (both for the score
- and the parts)?
-
-- Bar numbers and marks are not printed on top of the staffs,
- but at one of the middle parts of the score. This may be
- related to the problem with the brackets, since the
- corresponding StaffGroup is the only one to get a bracket,
- even though it is misplaced horisontally.
-
-- The score extends too high on the page, it often overwrites the
- page number. LaTeX warns about overfull boxes. I'll take a look
- at the page layout.
-
-. * control paper-size/-file from commandline ?

-. * detangle ly/* paper-params papersize stuff
-. * fix tremolos.
-. * change ) c4 to c4-)
-. * automated marks.
-. * There should be no pagebreak below the title of the movement!!
-. * tempo:
-
-> - Tempo Indications:
-> * \tempo 4 = 60 should be printed
-> * There should be commands like \alloegro that also do something
-> sensible in midi.
->
-. * - It should be possible to have Bar numbers on every bar.
-
-. * dynamics:
-> * Notes should be spaced out for crescendos (had to use c^" ")
-> * something like c-.->\ff looks ugly. The dynamc indication should
-> appear left of the marks
->
-. *
-There's insufficient leading between lines of lyrics, so risers like
-`l' and 'b' collide with the bottom of the line above.
-
-Also the lines are unevenly spaced.
-
-. * write comments in the source code
-. * internationalize GUILE msgs.
-. * roy rankin:
-1> The volta brackets are on top of the lyrics. This problem existed in
- 1.2.x which I corrected by giving the brackets a vertical size. I
- have not had the time to check what is going on in 1.3.
-
-2> Part names are being written on top of the staff and not in the
- left margin.
-
-3> The tag at the end is spaced out clear across the page. (new problem
- in 1.3.27)
-
-I also get the following error messages from ly2dvi.
-. * unbroken marks.
-. * chubb:
--- Take a piece of early music, and typeset it as closely as possible to
-the original edition. This means: moveable clefs, sometimes funny or no
-time signatures, few or no bar lines, few or no ties, slurs or
-phrasemarks, ornaments implied by the structure of the music, or
-indicated by, e.g., one or more thick lines through the stem of a note
-(Purcell and Farnaby both use this extensively, but with rather
-different meanings). For Dowland's music it may also mean being able
-to rotate one or more staves (but I can do this in LaTeX).
-
--- Add to this music a set of critical marks that:
- * regularises clef, time and key signature.
- * add slurs, phrase marks, articulation, etc.
- * Halve or quarter the durations, so that minims become crotchets, say.
- * add ornaments (mordents, trills, turns etc)
- * add regular barlines (which sometimes will mean splitting a note
- and adding a tie, e.g., in some of Byrd's music)
- * Add footnotes to particular symbols, groups of notes, etc.
- * When translating from chant notation, add a square bracket over a
- group of notes to indicate a ligature in the original
-etc.

-. * \context Staff <

-. * \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.
-. * 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.

-. * uniformise recent feta contributions.
-. * bigger and fatter 4/4 C

- 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.

-. * 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

-. * more intelligent file searching
-. * disable spaces in TeX stuff

-
-.* FONT
-. * the bracket is ugly (wings are too parabolic, should be more circular)
-. * fix accordion turning paths.
-. * versioning for Feta
-. * rewrite dynamic signs. They're kind of spaghetti now.
-. * The `3' in the meter key is a one or two pixels too thin (at 600dpi)

-. * design macro for penstroke with rounded endings
-. * timesig C: fat yet less curved. Check out relations.
-. * design decent macro for bulbed endings
-. * printer dependencies.
-. * versioning
-. * lo-res fixes.
-. * work out sizes of character fonts.
-. * more symbols
-. * piano pedals: Ped/*

-> Before, the font was changed with macros declared separately for
-> pure TeX and LaTeX, but now all the fonts are declared directly in
-> the generated code using the low-level TeX commands. This circumvents
-> the fontencoding mechanism of LaTeX and is a potential source of
-> problems also for us users of the Latin-1 character set.
-> I think it still works since the inputencoding latin1 is
-> declared by ly2dvi, but it still means that e.g. an o with
-> umlaut is typeset as a combination of the two symbols 'o' and
-> 'umlaut' instead of as a single character, as would be the case
-> if fontencoding OT1 had been used. This shouldn't give any
-> difference in layout, though. One of the main argument for using
-> fontencoding OT1 is for the hyphenation mechanism to work, an
-> argument that's clearly irrelevant in our application. Yet we
-> see the problem for August.
