Most of the items are marked in the code as well
-Grep for TODO and ugh/ugr/urg.
-
-.* TODO before 1.2
-. * rename 'staff_line_leading' (who is being lead where?) to
-staff_space, interline; (or other meaningful name) and use throughout
-lily
-
-[-> leading are the lead strips between the sticks (lines) of
-typeface. ie. leading is vertical space --hwn]
-. * Rewrite \rhythm to be during interpreting.
-. * move \version check to lexer.ll
-. * junk delayed spanner breaking.
-. * core dump on broken (de)crescendo
-. * align left edge of broken (de)cresc/slur/tie/tuplet/volta
-. * check dangling_scm_sym working.
-. * spacing of accidentals
-. * key restorations & repeats
+Grep -i for TODO, FIXME and ugh/ugr/urg.
+
+.* TODO
+. * use Rhythmic_head::position_i () for all Staff_referenced
+. * .po -> .pot.
+. * setting indent to 0 with \shape fails
+. * hara kiri _8 clef.
+. * junk -M ?
+. * mudela-book doco
+. * rerun profile
+. * fix or replace feta-accordion.mf
+. * fix configure with CFLAGS or LDFLAGS, try:
++ CFLAGS=-g LDFLAGS='-Wl,--warn-common' ./configure
++ configure will use them while testing the compiler, but they don't
++ appear in config.make
+
+. * Break_req handling is silly (break_forbid () + \break fucks up.)
+. * script engraver
+. * Chords:
+. * Bass/inversion pitch when not part of Chord
+Sometimes a series of changing chords will be blocked out over a static tone
+in the bass, usually this was referred to as a pedal tone (and it's been
+continued to be used, even in contemporary music). Another less frequently
+used practice is putting a non-chordal tone in the bass (that is not acting
+as a pedal tone) in order to create tension or make a more colorful sound.
+There are examples of this in the classsical literature, but its use is much
+more prevalent today. For example, the chord sequence Dm7 - Dm7/G is such a
+sequence, and the Dm7/G defies easy classification. Is it a G7(no 3rd)add
+9/11? Or is it a G7(no 3rd)add2/4? Or perhaps Dm7 add11? It's a heck of a
+lot easier to read to just leave it as Dm7/G!
+. * Diminished does not mean 5-
+When speaking of a chord, dimished can mean one of two things: A diminished
+triad or a dimished seventh chord (which is distinctly different from what's
+known as the 'half-diminished' chord). The triad is a root with a flat
+third and flat fifth, and is notated (at least in America, someone else will
+have to fill me in on other countries) as (using C as the root) Cdim, or Co.
+The diminished seventh has a root with a flat third, flat fifth, and a
+doubly flatted seventh (which is enharmonically equivalent to a sixth, and
+from which comes tons of confusion). It is usually notated as (again, using
+C as the root) Cdim7 or Co7.
+
+. * Mondrup:
+
+- I would like the possibility of forcing clef- and key- changes to be
+printed _after_ the new bar line
+
+- I would like an option to define the number of systems on which the
+score must be distributed. As it is now it seems that I may only
+influence that indirectly through the gourlay_maxmeasures property.
+
+- 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
+
+- for one of my test scores containing a modern edition of an early
+17'th century composition I have a leading measure containing the
+orginal clefs and note values of the original composition. I use the
+"harmonic" and "diamond" note head styles for that measure and would
+like to have the stems of these notes _centered_ on the notehead as in
+the mensural music notation.
+
+- 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
+
+- autoBeamMelisma: if I explicitly beam notes in a staff with auto
+beaming disabled I would like to have these beams also to be
+melismatic.
+
+. * make all Feta (including dynamics) available to the user in
+ textual scripts. Examples: "D.S. al \coda", "\mf espress.".

+. * We need feta-din*.mf files for more sizes than 10.
+- Rests and beams don't work too well together. Example:
+ [ r8 g''16 des'] [r8 c16 a]
-In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
+- The stemLength property should affect also beamed stems.

+. * fix dynamics decently, ie. use kerning & ligatures.
+. * key restorations & repeats
+. * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
+. * * auto melismaBusy for beams.
+. *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 26, there's a \p marker that should appear below the grace
-note.
-
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.
-
-How do I specify these?
-. * spanners from grace to normal ctxt
-. * Glen:

+. * 5. Sometimes lyrics extend past the right end of the staff. I guess that
this is a similar problem (if not another symptom of the same problem) as
one of the spacing bugs mentioned in the TODO.
. * 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.
+. * decimal point in \paper {}
+. * tie-direction
+. * repeats and partial measures.
+. * 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.
. * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
-. * Rename illegal to invalid
-. * Mats:
-
-- The Postscript output is still very experimental
-
-- It is impossible to typeset two textual scripts that are stacked
+. * It is impossible to typeset two textual scripts that are stacked
on top of eachother 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
be stacked vertically, avoiding collisions with the notes
in all voices.
-- 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.
