4 * Rewrote Staff_margin_engraver. Staff margin texts now hang on a new
5 breakable item: Left_edge_item.
7 * Fixed vertical alignment for dynamic elements. Orphaned dynamic items
8 (not supported by a Dynamic_line_spanner) still collide with Staff,
9 although they now have staff support, which was supposed to fix this.
14 * Fixed Staff_margin_engraver for "instrument", "instr" is still broken.
16 * Dynamic elements are only put in a Dynamic_line_spanner if there
17 actually is more than one adjacent note-column with a dynamic.
18 This breaks the fine looks of all dynamics, again :-)
26 * Experiment: use STL map for Scheme_hash_table; Is there a speedup?
28 * Bugfix: print brace iso. bracket for Piano / GrandStaff
30 * Change naming: change do_post_processsing into after_line_breaking,
31 do_pre_processsing into before_line_breaking and do_process_requests
32 into do_process_music.
34 * Bugfix in hash-table.hh: do quadratic probing, and not cubic probing.
36 * Display property name for type error.
38 * Cleanups for Dynamic_engraver and Dynamic_line_spanner.
40 * Warn if last column in score is musical. Helps catch programming errors.
42 * Spanner::spanned_drul_ now is private.
44 * Rewrote some bar code: moved molecule functions out of Lookup.
49 * Embedded newlines in text items are now allowed. This helps avoiding
50 TeX-hacking in some cases. See input/test/coriolan-margin.ly
52 * Fixed stupid x-y interchange bug for staff-bracket. This fixes
53 placement of staff-brackets.
55 * Fixed bracket/arch-thickness interchange bug, and made bracket a bit
58 * Fixed slur/bezier-beautiful name mismatch. This should fix the steep
59 slurs that were apparently reintroduced in 1.3.29.
61 * Made some small fixes to Coriolan.
63 * Removed duplicate lily/output-property-engraver.hh.
65 * Removed optional use of vanilla spanner in Dynamic_engraver.
67 * Fixed (measured) tremolo for Stem and Beam. Merged declarations
68 stem-engraver.hh and chord-tremolo-engraver.hh into their .cc
69 implementation file. Also fixed looks of Chord tremolo, input and
70 implementation is still ugly.
72 * Added *.yy and *.ll to TAGS, to that tags-find-replace doesn't omit
78 * Fixed \specialkey and \normalkey. Updated documentation.
85 * Fixed and cleaned-up Dynamic_engraver. Optionionally uses vanilla
86 spanner instead of Dynamic_line_spanner.
88 * Made gcc-2.95 compile fix in libc-extension.
90 * Various fixes to Coriolan, score starts to look acceptable.
92 * Moved optional text of crescendo into Crescendo spanner. Fixed horizontal
93 and vertical alignment of dynamics.
95 * Added new text crescendo spanners to Coriolan and made some fixes.
96 If you're using timidity, use the -EO option to prevent notes get
97 stuck. I'm not sure whose fault this is, Lily's MIDI output may be
98 stretching the standard a bit.
100 * Adjacent dynamic markings are now grouped on a horizontal line, but it's
101 not perfect yet: they're always below the staff and no horizontal spacing
102 is done. Also, character metrics of dynamics are still not used.
103 See: input/test/crescendi.ly and input/test/dyn-line.ly
105 * Cleaned up Span_dynamic_performer.
112 * Fixed the page layout, reintroducing space for the header and
113 trying to keep piece titles on the same page as the piece.
114 The header and footer can now contain several lines.
119 * Lily now also performs crescendi and decrescendi in MIDI output:
120 Span_dynamic_performer (bit scrappy).
122 * Added preliminary support for crescendi/decrescendi other than `hairpins',
123 eg: `cresc. poco `a poco -- -- --'
125 * Made MIDI tie performance fix.
130 * Lily now performs absolute dynamics in MIDI output.
132 * Included David's comments on opus47 in TODO.
137 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
138 fixes and remainder french horn-1,2; trombone-1,2;
139 fagotto-1,2; timpani; and several fixes.
144 * Remove some old doco from programmer/ and put on personal homepage.
146 * Removed union-find from flower library.
148 * Only quantise tie horizontal part inside the staff.
155 * Report type errors for \property. Helps with converting 1.2 input
157 * Use Scheme for Align_element; fixed graceAlignPosition
158 and removed \property alignmentReference in the process.
160 * Use generic properties for lyrics too. This fixes \property
164 * Add relative distance for constraints between non-column items.
166 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
167 increased automatically.
169 * Translators now only change properties of their own context. This
170 removes the 2nd argument to Translator::get_property()
172 * Bugfix for Metapost mode
177 * Updates of glossary (Christian Mondrup)
179 * Bugfix with bar number placement
181 * Moved links to bibliography/ and misc/ to main index.
186 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
187 Slurs are now calculated just once.
189 * Bezier_bow gets constants from paper. Still no sensible solution for
190 magic asymmetry gradient step constants.
192 * Reinstantiated tangent-controls, more flexible than ever. You can choose
193 between area asymmetry and tangent-controls. My guess is, tangent controls
194 will be junked in 1.3.30.
196 * Slur area: only look at x-gradient.
198 * Added credits for some symbols of as5/9 fonts.
200 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
202 * Bugfix: midi2ly put out recent version (ugh).
207 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
210 * Removed Gade score. To appear (shortly?) on Mutopia.
212 * Make Bar_script_engraver look for typeVisibilityFunction (eg
213 property barNumberVisibilityFunction). Changed the names of the Scheme
214 functions to be understandable. See input/test/bar-script-visibility.ly
216 * rewrite of class Molecule. It has now reached the ultimate quality
217 plateau. All molecule data is now shared.
222 * Update of the glossary by Christian Mondrup
224 * Moved horn-concerto-3 out of tarball to private website, removed
225 W.A.Mozart subdirectory.
230 * Bugfix: don't make giant ties if the horizontal part of tie is near
233 * Small optimizations to be a little more careful with mem usage.
235 * Website change: put all examples in one directory.
237 * Removed Atom as a separate type. Now use SCM, and since we use
238 function composition, Atoms are immutable, so they don't have to be
239 copied. This makes life easier, hopefully this is quicker and uses
245 * Bezier_bow: minimise_enclosed_area
253 * Tuplet-spanner slope calculation now looks better on tupletted rests
254 (patch courtesy Laurent Martelli)
256 * Bugfix (Staff_performer::new_instrument_str ()) check type of
257 \property "instrument"
259 * New mechanism for breaking lines: do not copy & prune the element
260 property list separately, but combine these steps. Dramatically
261 reduces memory usage for large scores.
268 * Bugfix: font used in volta-spanner calculation.
270 * Added simple selection list to webpage, inspired by sawmill.
272 * Devised kludge for ascii 5 character font pitches.
274 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
279 * Plug memory leaks related to Moment:
280 - Spacing_engraver::do_pre_move_processing ()
281 - make_rational ()/make-rational
282 - Paper_column::Paper_column ()
284 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
286 * Plug memory leak in Score_engraver::set_columns ()
288 * Plug memory leak in Scheme_hash_table::set()
290 * Plug memory leak in Score_element::molecule_extent ()
292 * Bugfix: don't crash if a slur doesn't span anything.
294 * Bugfix: don't crash if doing beams without a staff symbol.
296 * Generic element property setting:
298 \outputproperty #predicate #'symbol = #value
300 Will set the element property symbol to value, for any elements that
301 return true for PREDICATE. This allows you to virtually tweak *ANY*
302 property of the output. Example in input/test/generic-output-property.ly
307 * lilypond as as2ly: --help and --version to stdout. Regular identify
308 to stderr. This fixes help2man's manpage generation.
310 * configure: substitute full path for perl and guile in scripts.
312 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
314 * Bugfix: default font now user settable
316 * as2text: handle plain ascii font, read from stdin, you can now do:
318 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
323 * Bugfix: second half of broken ties now are displayed again.
325 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
326 it horizontally on the clef.
328 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
330 * Bugfix: unbroken repeat barlines now work, eg. |:
332 * Added Request_iterator to make more flexible constructions possible.
336 * as2text: catch missing font/character errors, added default font, set text.
338 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
340 * Ascii output, minimal support:
341 - AsciiScript Fonts: mf/*.af
342 - Init files: ly/*-as.*ly
343 - AsciiScript translation to text: scripts/as2text.scm
344 - input/test/as.fly input/test/as1.fly
345 - Output support: lily/lily.scm
347 lilypond -f as -i init-as.fly input/test/as.fly
353 * The horizontal part of ties will avoid collision with staff lines.
355 * Plugged memory leak: don't protect Atom function.
357 * Lookup cleanups. Made lots of functions static. Moved some code out
365 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
366 does not delete any of the file_ly*.tex.
368 * Added header and footer support in ly2dvi.py
373 * Added a ROADMAP file explaining the source directory layout.
375 * Minor tweak in the feta 6 and 9 numeral
377 * Moved files from lib/ to flower/
379 * Removed Note_head_side class.
381 * Updated the webpage to be a little more chatty.
383 * Small Local_key_engraver optimization: only lookup timing engraver once.
387 * Rewrite of Slur code. Be much more picky about slur shapes. We try
388 to offset the slur instead of bending it too much
390 * Look at stem directions for tie direction.
392 * Compound multimeasure rests. Put measures_i_ variable in an element
393 property. Made the symbol a lot wider.
395 * Time signature small cleanups.
400 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
403 * Breathing marks now have a direction by default.
405 * Do set generic script properties.
407 * Also put tuplet brackets under notes.
409 * Score_element_info: only store origin of element, but not the path
410 to parent translators. Saves a little memory, and removes some complexity.
416 * Autobeaming in time sigs that don't have 1/4 beats fixed.
418 * (De)crescendi should now work. (Thanks Michael)
420 * Better error reporting for conflicting time signatures.
422 * Line_number_engraver: output locations of note head
423 definitions. Very handy when entering complicated scores.
425 * Rewrote multi measure rest support: now they are entered as spanners
426 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
428 { \commandspanrequest \start "rest"
430 \commandspanrequest \stop "rest"
433 * Removed support of percent style repetitions.
435 * Put texts outside the staff.
439 * Getopt bugfix: don't assert on certain errors.
441 * ly2dvi: Remove unnecessary space for the page headers.
443 * Bugfix convert-mudela
448 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
451 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
452 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
453 \property tupletInvisible will stop all tuplet spanner creation.
455 * Don't go berserk if tuplet spanner is on only one column.
457 * Use SCMs & Smobs for Molecules & atoms. This uses less
458 scm_(un)protect_object () calls, so the output stage should be faster.
460 * Added \property tupletSpannerDuration, to make multiple tuplet signs
463 * Some programming Errors in spacing are now caught. Lily does not
464 hang when encountering degenerate springs.
466 * Allow beams to start and end over rests
470 * Fix disappearing clefs when clefs are not printed with a barline.
475 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
476 input/test/beam-control.fly
477 * Added \context Voice to .fly and .sly; the default \context Staff is almost
478 never what you expect
479 * Fixed decision for .sly/.fly in lilypond-mode.
484 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
485 Cleanup mf-to-table.py
487 * Fixed embarassing slur bug.
492 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
497 * lilypond-mode.el for emacs supersedes mudela-mode.el
499 * Tuplet spanners don't collide with encompassing notes.
501 * Gobbled Adobe parseAFM* code, for future use.
503 * Big 1999 to 2000 search/replace.
505 * Big interline to staff_space search/replace for mf files.
507 * Removed Bow class, and split code into Tie and Slur
509 * Don't put scripts on grace notes.
511 * Font_metric uses SCM for name field.
513 * Various compilation fixes.
518 * Bugfix: beams with less than one (visible) stem
520 * small fixes to pa.ly
525 * Fixed bug that made multi-measure rest barnumber counts go wild.
526 (even more scm2int/int2scm mixups!)
528 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
530 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
535 * Remove Paper_def calls in bezier-bow.cc
537 * Remove data members of Tuplet_spanner, Volta_spanner
539 * hang_on_clef, property hangOnClef removed
541 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
542 function to determine breaking behavior.
544 * More Scheme typechecking.
546 * Be strict about the difference between strings and symbols for conversion.
548 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
551 * Partial French translation, courtesy Laurent Martelli.
553 * Small corrections in NL translation.
558 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
559 we have a longa note head. noteHeadStyle = "harmonic" is not
560 supported anymore. (for now, that is)
562 * Reference manual update. Document \properties with examples
564 * fix mudela-book --help
566 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
567 Key_item::c0_position_
569 * Clef_engraver general cleanup. Use alists (\property
570 supportedClefTypes, clefPitches) for clef types.
572 * Use progress_indication () for progress. Don't include <iostream.h> directly
573 Don't include <string.h>, <math.h> from headers.
579 * \property stemCentered (boolean): centers stem on note head. See
580 input/test/stem-centered.ly
582 * input/trip.ly, small test of lots of features.
584 * \property Staff.collisionMergeDotted: merge equal noteheads
585 with different dot count. See input/test/collision-merge-dotted.fly
589 * Don't crash if a slur does not span any notes.
591 * Volta repeats fixed.
593 * cleanup of Note_heads_engraver
595 * removed dots_i_ member of Dots
599 * Fixed cross staff slurs. It seems that cross-staff sign
605 * Fixed bug in stem code. Stem in chords works again. Small
608 * Use element properties for Staff_symbol.
610 * \property sparseTies (boolean). Only make one tie in the
611 middle for tied chords.
613 * Junked Directional_spanner, Column_info.
614 Directional_element now is element interface `Directional_element_interface'
616 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
