4 * Fixed performance of (de)crescendi.
6 * Better documentation for arithmetic_multiplier and arithmetic_basicspace
9 * Added instrument-equaliser for MIDI output, see scm/midi.scm, and
10 properties midiMinimumVolume, midiMaximumVolume, ranges [0,1].
12 * Changed absolute midi volume settings into factor of full scale.
14 * Fixed another dynamic-line-spanner bug, it gets hairy.
16 * Added warning for spanners that are not fully contained in parent spanner.
22 * Abstract Align_element into Align_interface. Removed
23 Axis_align_{item,spanner}, Align_element, Super_element, all multiple
24 inheritance in the backend.
26 * new Gade score, INSTALL.texi fixes (thanks, Mats)
28 * Removed Item::hpos_f (), Score_element::{get,set}_real ()
30 * comments detailing properties for Axis_group_interface,
31 Side_position_interface, Score_element, Item and Spanner
36 * Fixed vertical dimensions of elements in dynamic line spanner by adding
37 axis-group to dynamic line spanner.
39 * Bugfix: line-spanner lasts always full duration of (de)crescendi.
41 * Bugfix: broken (de)crescendi on a dynamic-line-spanner.
43 * Bugfix: compilation dynamic-engraver.
45 * Added and updated a faq about postscript and ghostscript.
47 * Fixed order of slurVerticalDirection verticalDirection in
48 generic-property.scm. Similar fixes for Stem, Tie, etc.
50 * Added a Text_engraver to GraceContext. Maybe it was removed on
51 purpose: scripst on grace notes seem broken, they appear on the
54 * Bugfix: volume effect of (de)crescendi was sometimes wrong way round.
61 * textEmptyDimension changed into textNonEmpty, default: off,
62 ie. texts don't occupy space.
64 * Use STL map for Lookup::lookup_p_tab_p_
66 * Abstracted Axis_group_element into Axis_group_interface, and removed
67 Axis_group_element. This eliminates some multiple inheritance in the
73 * Added minimum-space property to Side_position_interface. Used in
74 positioning of Volta_spanner: voltaMinimumSpace.
76 * Fixed and cleaned-up volta-spanner.
78 * Moved directional-element.cc -> directional-element-interface.cc
80 * Renamed all `process_requests' to `process_music', which fixes
83 * Fixed dimensions (more x-y interchanges) of brace, bracket and
86 * Bit half-baken fix in to get similar vertical placement of orphaned vs.
87 line-spanned dynamic elements.
89 * Added property bracketCollapseHeight: the minimal size of a staff bracket
90 that will be typeset. Smaller brackets will not be displayed. This
91 fixes the (in 1.3.x reintroduced) funny duck-beak-bracket-bug (sorry).
93 * Removed some dissonant chords from Coriolan
98 * Removed Documentation/programmer directory
103 * Small enhancements to Staff_margin_engraver:
104 - by default, the marginScript left aligns the text
105 - to set the text style, use property marginScriptTextStyle
106 - to change the alignment, use property marginScriptHorizontalAlignment
107 (centred and right alignment require manual padding settings).
109 * Print a friendly message if the manual pages failed to build.
111 * Bugfix: dynamicDirection now overrides verticalDirection setting.
113 * Warning messages and nl.po
115 * Fixed vertical alignment for all dynamic items and (reluctantly)
116 reinstated old directional behaviour for orphaned dynamics.
118 * Finished maximumRestCount property.
125 * Print key without setting key, syntax "\key ;". General cleanups of
128 * Add paragraph tags in HTML output of mudela-book. Music fragment
129 don't run into the text anymore.
131 * Bugfix: don't align the first line of text. (Lookup::text ()).
133 * Abstract away data members of Axis_group_element, Align_element
139 * Added helpful properties instrumentScriptPadding/instrScriptPadding for
140 Staff_margin_engraver.
142 * Removed some empty files, substituted (c) 1999 occurrences.
144 * Added \property maximumRestCount. It will prevent showing (or actually:
145 moving in case of a collision) more than maximumRestCount similar rests.
148 * Rewrote Staff_margin_engraver. Staff margin texts now hang on a new
149 breakable item: Left_edge_item.
151 * Fixed vertical alignment for dynamic elements. Orphaned dynamic items
152 (not supported by a Dynamic_line_spanner) still collide with Staff,
153 although they now have staff support, which was supposed to fix this.
155 * Fixed Staff_margin_engraver for "instrument", "instr" is still broken.
157 * Dynamic elements are only put in a Dynamic_line_spanner if there
158 actually is more than one adjacent note-column with a dynamic.
159 This breaks the fine looks of all dynamics, again :-)
168 * Experiment: use STL map for Scheme_hash_table; Is there a speedup?
170 * Bugfix: print brace iso. bracket for Piano / GrandStaff
172 * Change naming: change do_post_processsing into after_line_breaking,
173 do_pre_processsing into before_line_breaking and do_process_requests
174 into do_process_music.
176 * Bugfix in hash-table.hh: do quadratic probing, and not cubic probing.
178 * Display property name for type error.
180 * Cleanups for Dynamic_engraver and Dynamic_line_spanner.
182 * Warn if last column in score is musical. Helps catch programming errors.
184 * Spanner::spanned_drul_ now is private.
186 * Rewrote some bar code: moved molecule functions out of Lookup.
191 * Embedded newlines in text items are now allowed. This helps avoiding
192 TeX-hacking in some cases. See input/test/coriolan-margin.ly
194 * Fixed stupid x-y interchange bug for staff-bracket. This fixes
195 placement of staff-brackets.
197 * Fixed bracket/arch-thickness interchange bug, and made bracket a bit
200 * Fixed slur/bezier-beautiful name mismatch. This should fix the steep
201 slurs that were apparently reintroduced in 1.3.29.
203 * Made some small fixes to Coriolan.
205 * Removed duplicate lily/output-property-engraver.hh.
207 * Removed optional use of vanilla spanner in Dynamic_engraver.
209 * Fixed (measured) tremolo for Stem and Beam. Merged declarations
210 stem-engraver.hh and chord-tremolo-engraver.hh into their .cc
211 implementation file. Also fixed looks of Chord tremolo, input and
212 implementation is still ugly.
214 * Added *.yy and *.ll to TAGS, to that tags-find-replace doesn't omit
220 * Fixed \specialkey and \normalkey. Updated documentation.
227 * Fixed and cleaned-up Dynamic_engraver. Optionionally uses vanilla
228 spanner instead of Dynamic_line_spanner.
230 * Made gcc-2.95 compile fix in libc-extension.
232 * Various fixes to Coriolan, score starts to look acceptable.
234 * Moved optional text of crescendo into Crescendo spanner. Fixed horizontal
235 and vertical alignment of dynamics.
237 * Added new text crescendo spanners to Coriolan and made some fixes.
238 If you're using timidity, use the -EO option to prevent notes get
239 stuck. I'm not sure whose fault this is, Lily's MIDI output may be
240 stretching the standard a bit.
242 * Adjacent dynamic markings are now grouped on a horizontal line, but it's
243 not perfect yet: they're always below the staff and no horizontal spacing
244 is done. Also, character metrics of dynamics are still not used.
245 See: input/test/crescendi.ly and input/test/dyn-line.ly
247 * Cleaned up Span_dynamic_performer.
254 * Fixed the page layout, reintroducing space for the header and
255 trying to keep piece titles on the same page as the piece.
256 The header and footer can now contain several lines.
261 * Lily now also performs crescendi and decrescendi in MIDI output:
262 Span_dynamic_performer (bit scrappy).
264 * Added preliminary support for crescendi/decrescendi other than `hairpins',
265 eg: `cresc. poco `a poco -- -- --'
267 * Made MIDI tie performance fix.
272 * Lily now performs absolute dynamics in MIDI output.
274 * Included David's comments on opus47 in TODO.
279 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
280 fixes and remainder french horn-1,2; trombone-1,2;
281 fagotto-1,2; timpani; and several fixes.
286 * Remove some old doco from programmer/ and put on personal homepage.
288 * Removed union-find from flower library.
290 * Only quantise tie horizontal part inside the staff.
297 * Report type errors for \property. Helps with converting 1.2 input
299 * Use Scheme for Align_element; fixed graceAlignPosition
300 and removed \property alignmentReference in the process.
302 * Use generic properties for lyrics too. This fixes \property
306 * Add relative distance for constraints between non-column items.
308 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
309 increased automatically.
311 * Translators now only change properties of their own context. This
312 removes the 2nd argument to Translator::get_property()
314 * Bugfix for Metapost mode
319 * Updates of glossary (Christian Mondrup)
321 * Bugfix with bar number placement
323 * Moved links to bibliography/ and misc/ to main index.
328 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
329 Slurs are now calculated just once.
331 * Bezier_bow gets constants from paper. Still no sensible solution for
332 magic asymmetry gradient step constants.
334 * Reinstantiated tangent-controls, more flexible than ever. You can choose
335 between area asymmetry and tangent-controls. My guess is, tangent controls
336 will be junked in 1.3.30.
338 * Slur area: only look at x-gradient.
340 * Added credits for some symbols of as5/9 fonts.
342 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
344 * Bugfix: midi2ly put out recent version (ugh).
349 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
352 * Removed Gade score. To appear (shortly?) on Mutopia.
354 * Make Bar_script_engraver look for typeVisibilityFunction (eg
355 property barNumberVisibilityFunction). Changed the names of the Scheme
356 functions to be understandable. See input/test/bar-script-visibility.ly
358 * rewrite of class Molecule. It has now reached the ultimate quality
359 plateau. All molecule data is now shared.
364 * Update of the glossary by Christian Mondrup
366 * Moved horn-concerto-3 out of tarball to private website, removed
367 W.A.Mozart subdirectory.
372 * Bugfix: don't make giant ties if the horizontal part of tie is near
375 * Small optimizations to be a little more careful with mem usage.
377 * Website change: put all examples in one directory.
379 * Removed Atom as a separate type. Now use SCM, and since we use
380 function composition, Atoms are immutable, so they don't have to be
381 copied. This makes life easier, hopefully this is quicker and uses
387 * Bezier_bow: minimise_enclosed_area
395 * Tuplet-spanner slope calculation now looks better on tupletted rests
396 (patch courtesy Laurent Martelli)
398 * Bugfix (Staff_performer::new_instrument_str ()) check type of
399 \property "instrument"
401 * New mechanism for breaking lines: do not copy & prune the element
402 property list separately, but combine these steps. Dramatically
403 reduces memory usage for large scores.
410 * Bugfix: font used in volta-spanner calculation.
412 * Added simple selection list to webpage, inspired by sawmill.
414 * Devised kludge for ascii 5 character font pitches.
416 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
421 * Plug memory leaks related to Moment:
422 - Spacing_engraver::do_pre_move_processing ()
423 - make_rational ()/make-rational
424 - Paper_column::Paper_column ()
426 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
428 * Plug memory leak in Score_engraver::set_columns ()
430 * Plug memory leak in Scheme_hash_table::set()
432 * Plug memory leak in Score_element::molecule_extent ()
434 * Bugfix: don't crash if a slur doesn't span anything.
436 * Bugfix: don't crash if doing beams without a staff symbol.
438 * Generic element property setting:
440 \outputproperty #predicate #'symbol = #value
442 Will set the element property symbol to value, for any elements that
443 return true for PREDICATE. This allows you to virtually tweak *ANY*
444 property of the output. Example in input/test/generic-output-property.ly
449 * lilypond as as2ly: --help and --version to stdout. Regular identify
450 to stderr. This fixes help2man's manpage generation.
452 * configure: substitute full path for perl and guile in scripts.
454 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
456 * Bugfix: default font now user settable
458 * as2text: handle plain ascii font, read from stdin, you can now do:
460 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
465 * Bugfix: second half of broken ties now are displayed again.
467 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
468 it horizontally on the clef.
470 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
472 * Bugfix: unbroken repeat barlines now work, eg. |:
474 * Added Request_iterator to make more flexible constructions possible.
478 * as2text: catch missing font/character errors, added default font, set text.
480 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
482 * Ascii output, minimal support:
483 - AsciiScript Fonts: mf/*.af
484 - Init files: ly/*-as.*ly
485 - AsciiScript translation to text: scripts/as2text.scm
486 - input/test/as.fly input/test/as1.fly
487 - Output support: lily/lily.scm
489 lilypond -f as -i init-as.fly input/test/as.fly
495 * The horizontal part of ties will avoid collision with staff lines.
497 * Plugged memory leak: don't protect Atom function.
499 * Lookup cleanups. Made lots of functions static. Moved some code out
507 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
508 does not delete any of the file_ly*.tex.
510 * Added header and footer support in ly2dvi.py
515 * Added a ROADMAP file explaining the source directory layout.

519 * Moved files from lib/ to flower/
521 * Removed Note_head_side class.
523 * Updated the webpage to be a little more chatty.
525 * Small Local_key_engraver optimization: only lookup timing engraver once.
529 * Rewrite of Slur code. Be much more picky about slur shapes. We try
530 to offset the slur instead of bending it too much
532 * Look at stem directions for tie direction.
534 * Compound multimeasure rests. Put measures_i_ variable in an element
535 property. Made the symbol a lot wider.
537 * Time signature small cleanups.
542 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
545 * Breathing marks now have a direction by default.
547 * Do set generic script properties.
549 * Also put tuplet brackets under notes.
551 * Score_element_info: only store origin of element, but not the path
552 to parent translators. Saves a little memory, and removes some complexity.
558 * Autobeaming in time sigs that don't have 1/4 beats fixed.
560 * (De)crescendi should now work. (Thanks Michael)
562 * Better error reporting for conflicting time signatures.
564 * Line_number_engraver: output locations of note head
565 definitions. Very handy when entering complicated scores.
567 * Rewrote multi measure rest support: now they are entered as spanners
568 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
570 { \commandspanrequest \start "rest"
572 \commandspanrequest \stop "rest"
575 * Removed support of percent style repetitions.
577 * Put texts outside the staff.
581 * Getopt bugfix: don't assert on certain errors.
583 * ly2dvi: Remove unnecessary space for the page headers.
585 * Bugfix convert-mudela
590 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
593 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
594 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
595 \property tupletInvisible will stop all tuplet spanner creation.
597 * Don't go berserk if tuplet spanner is on only one column.
599 * Use SCMs & Smobs for Molecules & atoms. This uses less
600 scm_(un)protect_object () calls, so the output stage should be faster.
602 * Added \property tupletSpannerDuration, to make multiple tuplet signs
605 * Some programming Errors in spacing are now caught. Lily does not
606 hang when encountering degenerate springs.
608 * Allow beams to start and end over rests
612 * Fix disappearing clefs when clefs are not printed with a barline.
617 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
618 input/test/beam-control.fly
619 * Added \context Voice to .fly and .sly; the default \context Staff is almost
620 never what you expect
621 * Fixed decision for .sly/.fly in lilypond-mode.
626 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
627 Cleanup mf-to-table.py
629 * Fixed embarassing slur bug.
634 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
639 * lilypond-mode.el for emacs supersedes mudela-mode.el
641 * Tuplet spanners don't collide with encompassing notes.
643 * Gobbled Adobe parseAFM* code, for future use.
645 * Big 1999 to 2000 search/replace.
647 * Big interline to staff_space search/replace for mf files.
649 * Removed Bow class, and split code into Tie and Slur
651 * Don't put scripts on grace notes.
653 * Font_metric uses SCM for name field.
655 * Various compilation fixes.
660 * Bugfix: beams with less than one (visible) stem
662 * small fixes to pa.ly
667 * Fixed bug that made multi-measure rest barnumber counts go wild.
668 (even more scm2int/int2scm mixups!)
670 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
672 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
677 * Remove Paper_def calls in bezier-bow.cc
679 * Remove data members of Tuplet_spanner, Volta_spanner
681 * hang_on_clef, property hangOnClef removed
683 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
684 function to determine breaking behavior.
686 * More Scheme typechecking.
688 * Be strict about the difference between strings and symbols for conversion.
690 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
693 * Partial French translation, courtesy Laurent Martelli.
695 * Small corrections in NL translation.
700 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
701 we have a longa note head. noteHeadStyle = "harmonic" is not
702 supported anymore. (for now, that is)
704 * Reference manual update. Document \properties with examples
706 * fix mudela-book --help
708 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
709 Key_item::c0_position_
711 * Clef_engraver general cleanup. Use alists (\property
712 supportedClefTypes, clefPitches) for clef types.
714 * Use progress_indication () for progress. Don't include <iostream.h> directly
715 Don't include <string.h>, <math.h> from headers.
721 * \property stemCentered (boolean): centers stem on note head. See
722 input/test/stem-centered.ly
724 * input/trip.ly, small test of lots of features.
726 * \property Staff.collisionMergeDotted: merge equal noteheads
727 with different dot count. See input/test/collision-merge-dotted.fly
731 * Don't crash if a slur does not span any notes.
733 * Volta repeats fixed.
735 * cleanup of Note_heads_engraver
737 * removed dots_i_ member of Dots
741 * Fixed cross staff slurs. It seems that cross-staff sign
747 * Fixed bug in stem code. Stem in chords works again. Small
750 * Use element properties for Staff_symbol.
752 * \property sparseTies (boolean). Only make one tie in the
753 middle for tied chords.
755 * Junked Directional_spanner, Column_info.
756 Directional_element now is element interface `Directional_element_interface'
758 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
