7 * (generic-property.scm) added tieDash
9 * Removed ly_eval_str(), we should use scm_eval (Scm_object).
11 * Removed scm_to_array (), array_to_scm (), associated junk. Reverted
12 undocumented .29 patch that made Bezier::control_ into an
13 Array<Offset>. Added some comments documenting the reasons for the
16 * Revert generic-property.scm of .37 fix, fix the real problem in
17 property-engraver.cc: use the right symbol to check if element
18 property is already set.
23 * Fixed srcdir build, so that you can do:
25 tar xzf releases/lilypond-x.y.z
28 ../lilypond-x.y.z/configure
31 as with any other gnu package. All build output goes to <build>/out.
33 * Changed and fixed use of different configurations, and different output
34 directories. Finally, you can use different configurations alongside
35 eachother. From make/stepmake.make:
37 # Use alternate configurations alongside eachother:
39 # ./configure --enable-configsuffix=debug
42 # uses config-debug.make and config-debug.h; output goes to out-debug.
45 # Use same configuration, but different output directory:
49 # uses config.make and config.h; output goes to out-WWW.
53 * Fixed performance of (de)crescendi.
55 * Better documentation for arithmetic_multiplier and arithmetic_basicspace
58 * Added instrument-equaliser for MIDI output, see scm/midi.scm, and
59 properties midiMinimumVolume, midiMaximumVolume, ranges [0,1].
61 * Changed absolute midi volume settings into factor of full scale.
63 * Fixed another dynamic-line-spanner bug, it gets hairy.
65 * Added warning for spanners that are not fully contained in parent spanner.
73 * Abstract Align_element into Align_interface. Removed
74 Axis_align_{item,spanner}, Align_element, Super_element, all multiple
75 inheritance in the backend.
77 * new Gade score, INSTALL.texi fixes (thanks, Mats)
79 * Removed Item::hpos_f (), Score_element::{get,set}_real ()
81 * comments detailing properties for Axis_group_interface,
82 Side_position_interface, Score_element, Item and Spanner
87 * Fixed vertical dimensions of elements in dynamic line spanner by adding
88 axis-group to dynamic line spanner.
90 * Bugfix: line-spanner lasts always full duration of (de)crescendi.
92 * Bugfix: broken (de)crescendi on a dynamic-line-spanner.
94 * Bugfix: compilation dynamic-engraver.
96 * Added and updated a faq about postscript and ghostscript.
98 * Fixed order of slurVerticalDirection verticalDirection in
99 generic-property.scm. Similar fixes for Stem, Tie, etc.
101 * Added a Text_engraver to GraceContext. Maybe it was removed on
102 purpose: scripst on grace notes seem broken, they appear on the
105 * Bugfix: volume effect of (de)crescendi was sometimes wrong way round.
112 * textEmptyDimension changed into textNonEmpty, default: off,
113 ie. texts don't occupy space.
115 * Use STL map for Lookup::lookup_p_tab_p_
117 * Abstracted Axis_group_element into Axis_group_interface, and removed
118 Axis_group_element. This eliminates some multiple inheritance in the
124 * Added minimum-space property to Side_position_interface. Used in
125 positioning of Volta_spanner: voltaMinimumSpace.
127 * Fixed and cleaned-up volta-spanner.
129 * Moved directional-element.cc -> directional-element-interface.cc
131 * Renamed all `process_requests' to `process_music', which fixes
134 * Fixed dimensions (more x-y interchanges) of brace, bracket and
137 * Bit half-baken fix in to get similar vertical placement of orphaned vs.
138 line-spanned dynamic elements.
140 * Added property bracketCollapseHeight: the minimal size of a staff bracket
141 that will be typeset. Smaller brackets will not be displayed. This
142 fixes the (in 1.3.x reintroduced) funny duck-beak-bracket-bug (sorry).
144 * Removed some dissonant chords from Coriolan
149 * Removed Documentation/programmer directory
154 * Small enhancements to Staff_margin_engraver:
155 - by default, the marginScript left aligns the text
156 - to set the text style, use property marginScriptTextStyle
157 - to change the alignment, use property marginScriptHorizontalAlignment
158 (centred and right alignment require manual padding settings).
160 * Print a friendly message if the manual pages failed to build.
162 * Bugfix: dynamicDirection now overrides verticalDirection setting.
164 * Warning messages and nl.po
166 * Fixed vertical alignment for all dynamic items and (reluctantly)
167 reinstated old directional behaviour for orphaned dynamics.
169 * Finished maximumRestCount property.
176 * Print key without setting key, syntax "\key ;". General cleanups of
179 * Add paragraph tags in HTML output of mudela-book. Music fragment
180 don't run into the text anymore.
182 * Bugfix: don't align the first line of text. (Lookup::text ()).
184 * Abstract away data members of Axis_group_element, Align_element
190 * Added helpful properties instrumentScriptPadding/instrScriptPadding for
191 Staff_margin_engraver.
193 * Removed some empty files, substituted (c) 1999 occurrences.
195 * Added \property maximumRestCount. It will prevent showing (or actually:
196 moving in case of a collision) more than maximumRestCount similar rests.
199 * Rewrote Staff_margin_engraver. Staff margin texts now hang on a new
200 breakable item: Left_edge_item.
202 * Fixed vertical alignment for dynamic elements. Orphaned dynamic items
203 (not supported by a Dynamic_line_spanner) still collide with Staff,
204 although they now have staff support, which was supposed to fix this.
206 * Fixed Staff_margin_engraver for "instrument", "instr" is still broken.
208 * Dynamic elements are only put in a Dynamic_line_spanner if there
209 actually is more than one adjacent note-column with a dynamic.
210 This breaks the fine looks of all dynamics, again :-)
219 * Experiment: use STL map for Scheme_hash_table; Is there a speedup?
221 * Bugfix: print brace iso. bracket for Piano / GrandStaff
223 * Change naming: change do_post_processsing into after_line_breaking,
224 do_pre_processsing into before_line_breaking and do_process_requests
225 into do_process_music.
227 * Bugfix in hash-table.hh: do quadratic probing, and not cubic probing.
229 * Display property name for type error.
231 * Cleanups for Dynamic_engraver and Dynamic_line_spanner.
233 * Warn if last column in score is musical. Helps catch programming errors.
235 * Spanner::spanned_drul_ now is private.
237 * Rewrote some bar code: moved molecule functions out of Lookup.
242 * Embedded newlines in text items are now allowed. This helps avoiding
243 TeX-hacking in some cases. See input/test/coriolan-margin.ly
245 * Fixed stupid x-y interchange bug for staff-bracket. This fixes
246 placement of staff-brackets.
248 * Fixed bracket/arch-thickness interchange bug, and made bracket a bit
251 * Fixed slur/bezier-beautiful name mismatch. This should fix the steep
252 slurs that were apparently reintroduced in 1.3.29.
254 * Made some small fixes to Coriolan.
256 * Removed duplicate lily/output-property-engraver.hh.
258 * Removed optional use of vanilla spanner in Dynamic_engraver.
260 * Fixed (measured) tremolo for Stem and Beam. Merged declarations
261 stem-engraver.hh and chord-tremolo-engraver.hh into their .cc
262 implementation file. Also fixed looks of Chord tremolo, input and
263 implementation is still ugly.
265 * Added *.yy and *.ll to TAGS, to that tags-find-replace doesn't omit
271 * Fixed \specialkey and \normalkey. Updated documentation.
278 * Fixed and cleaned-up Dynamic_engraver. Optionionally uses vanilla
279 spanner instead of Dynamic_line_spanner.
281 * Made gcc-2.95 compile fix in libc-extension.
283 * Various fixes to Coriolan, score starts to look acceptable.
285 * Moved optional text of crescendo into Crescendo spanner. Fixed horizontal
286 and vertical alignment of dynamics.
288 * Added new text crescendo spanners to Coriolan and made some fixes.
289 If you're using timidity, use the -EO option to prevent notes get
290 stuck. I'm not sure whose fault this is, Lily's MIDI output may be
291 stretching the standard a bit.
293 * Adjacent dynamic markings are now grouped on a horizontal line, but it's
294 not perfect yet: they're always below the staff and no horizontal spacing
295 is done. Also, character metrics of dynamics are still not used.
296 See: input/test/crescendi.ly and input/test/dyn-line.ly
298 * Cleaned up Span_dynamic_performer.
305 * Fixed the page layout, reintroducing space for the header and
306 trying to keep piece titles on the same page as the piece.
307 The header and footer can now contain several lines.
312 * Lily now also performs crescendi and decrescendi in MIDI output:
313 Span_dynamic_performer (bit scrappy).
315 * Added preliminary support for crescendi/decrescendi other than `hairpins',
316 eg: `cresc. poco `a poco -- -- --'
318 * Made MIDI tie performance fix.
323 * Lily now performs absolute dynamics in MIDI output.
325 * Included David's comments on opus47 in TODO.
330 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
331 fixes and remainder french horn-1,2; trombone-1,2;
332 fagotto-1,2; timpani; and several fixes.
337 * Remove some old doco from programmer/ and put on personal homepage.
339 * Removed union-find from flower library.
341 * Only quantise tie horizontal part inside the staff.
348 * Report type errors for \property. Helps with converting 1.2 input
350 * Use Scheme for Align_element; fixed graceAlignPosition
351 and removed \property alignmentReference in the process.
353 * Use generic properties for lyrics too. This fixes \property
357 * Add relative distance for constraints between non-column items.
359 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
360 increased automatically.
362 * Translators now only change properties of their own context. This
363 removes the 2nd argument to Translator::get_property()
365 * Bugfix for Metapost mode
370 * Updates of glossary (Christian Mondrup)
372 * Bugfix with bar number placement
374 * Moved links to bibliography/ and misc/ to main index.
379 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
380 Slurs are now calculated just once.
382 * Bezier_bow gets constants from paper. Still no sensible solution for
383 magic asymmetry gradient step constants.
385 * Reinstantiated tangent-controls, more flexible than ever. You can choose
386 between area asymmetry and tangent-controls. My guess is, tangent controls
387 will be junked in 1.3.30.
389 * Slur area: only look at x-gradient.
391 * Added credits for some symbols of as5/9 fonts.
393 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
395 * Bugfix: midi2ly put out recent version (ugh).
400 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
403 * Removed Gade score. To appear (shortly?) on Mutopia.
405 * Make Bar_script_engraver look for typeVisibilityFunction (eg
406 property barNumberVisibilityFunction). Changed the names of the Scheme
407 functions to be understandable. See input/test/bar-script-visibility.ly
409 * rewrite of class Molecule. It has now reached the ultimate quality
410 plateau. All molecule data is now shared.
415 * Update of the glossary by Christian Mondrup
417 * Moved horn-concerto-3 out of tarball to private website, removed
418 W.A.Mozart subdirectory.
423 * Bugfix: don't make giant ties if the horizontal part of tie is near
426 * Small optimizations to be a little more careful with mem usage.
428 * Website change: put all examples in one directory.
430 * Removed Atom as a separate type. Now use SCM, and since we use
431 function composition, Atoms are immutable, so they don't have to be
432 copied. This makes life easier, hopefully this is quicker and uses
438 * Bezier_bow: minimise_enclosed_area
446 * Tuplet-spanner slope calculation now looks better on tupletted rests
447 (patch courtesy Laurent Martelli)
449 * Bugfix (Staff_performer::new_instrument_str ()) check type of
450 \property "instrument"
452 * New mechanism for breaking lines: do not copy & prune the element
453 property list separately, but combine these steps. Dramatically
454 reduces memory usage for large scores.
461 * Bugfix: font used in volta-spanner calculation.
463 * Added simple selection list to webpage, inspired by sawmill.
465 * Devised kludge for ascii 5 character font pitches.
467 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
472 * Plug memory leaks related to Moment:
473 - Spacing_engraver::do_pre_move_processing ()
474 - make_rational ()/make-rational
475 - Paper_column::Paper_column ()
477 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
479 * Plug memory leak in Score_engraver::set_columns ()
481 * Plug memory leak in Scheme_hash_table::set()
483 * Plug memory leak in Score_element::molecule_extent ()
485 * Bugfix: don't crash if a slur doesn't span anything.
487 * Bugfix: don't crash if doing beams without a staff symbol.
489 * Generic element property setting:
491 \outputproperty #predicate #'symbol = #value
493 Will set the element property symbol to value, for any elements that
494 return true for PREDICATE. This allows you to virtually tweak *ANY*
495 property of the output. Example in input/test/generic-output-property.ly
500 * lilypond as as2ly: --help and --version to stdout. Regular identify
501 to stderr. This fixes help2man's manpage generation.
503 * configure: substitute full path for perl and guile in scripts.
505 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
507 * Bugfix: default font now user settable
509 * as2text: handle plain ascii font, read from stdin, you can now do:
511 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
516 * Bugfix: second half of broken ties now are displayed again.
518 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
519 it horizontally on the clef.
521 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
523 * Bugfix: unbroken repeat barlines now work, eg. |:
525 * Added Request_iterator to make more flexible constructions possible.
529 * as2text: catch missing font/character errors, added default font, set text.
531 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
533 * Ascii output, minimal support:
534 - AsciiScript Fonts: mf/*.af
535 - Init files: ly/*-as.*ly
536 - AsciiScript translation to text: scripts/as2text.scm
537 - input/test/as.fly input/test/as1.fly
538 - Output support: lily/lily.scm
540 lilypond -f as -i init-as.fly input/test/as.fly
546 * The horizontal part of ties will avoid collision with staff lines.
548 * Plugged memory leak: don't protect Atom function.
550 * Lookup cleanups. Made lots of functions static. Moved some code out
558 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
559 does not delete any of the file_ly*.tex.
561 * Added header and footer support in ly2dvi.py
566 * Added a ROADMAP file explaining the source directory layout.

570 * Moved files from lib/ to flower/
572 * Removed Note_head_side class.
574 * Updated the webpage to be a little more chatty.
576 * Small Local_key_engraver optimization: only lookup timing engraver once.
580 * Rewrite of Slur code. Be much more picky about slur shapes. We try
581 to offset the slur instead of bending it too much
583 * Look at stem directions for tie direction.
585 * Compound multimeasure rests. Put measures_i_ variable in an element
586 property. Made the symbol a lot wider.
588 * Time signature small cleanups.
593 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
596 * Breathing marks now have a direction by default.
598 * Do set generic script properties.
600 * Also put tuplet brackets under notes.
602 * Score_element_info: only store origin of element, but not the path
603 to parent translators. Saves a little memory, and removes some complexity.
609 * Autobeaming in time sigs that don't have 1/4 beats fixed.
611 * (De)crescendi should now work. (Thanks Michael)
613 * Better error reporting for conflicting time signatures.
615 * Line_number_engraver: output locations of note head
616 definitions. Very handy when entering complicated scores.
618 * Rewrote multi measure rest support: now they are entered as spanners
619 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
621 { \commandspanrequest \start "rest"
623 \commandspanrequest \stop "rest"
626 * Removed support of percent style repetitions.
628 * Put texts outside the staff.
632 * Getopt bugfix: don't assert on certain errors.
634 * ly2dvi: Remove unnecessary space for the page headers.
636 * Bugfix convert-mudela
641 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
644 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
645 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
646 \property tupletInvisible will stop all tuplet spanner creation.
648 * Don't go berserk if tuplet spanner is on only one column.
650 * Use SCMs & Smobs for Molecules & atoms. This uses less
651 scm_(un)protect_object () calls, so the output stage should be faster.
653 * Added \property tupletSpannerDuration, to make multiple tuplet signs
656 * Some programming Errors in spacing are now caught. Lily does not
657 hang when encountering degenerate springs.
659 * Allow beams to start and end over rests
663 * Fix disappearing clefs when clefs are not printed with a barline.
668 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
669 input/test/beam-control.fly
670 * Added \context Voice to .fly and .sly; the default \context Staff is almost
671 never what you expect
672 * Fixed decision for .sly/.fly in lilypond-mode.
677 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
678 Cleanup mf-to-table.py
680 * Fixed embarassing slur bug.
685 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
690 * lilypond-mode.el for emacs supersedes mudela-mode.el
692 * Tuplet spanners don't collide with encompassing notes.
694 * Gobbled Adobe parseAFM* code, for future use.
696 * Big 1999 to 2000 search/replace.
698 * Big interline to staff_space search/replace for mf files.
700 * Removed Bow class, and split code into Tie and Slur
702 * Don't put scripts on grace notes.
704 * Font_metric uses SCM for name field.
706 * Various compilation fixes.
711 * Bugfix: beams with less than one (visible) stem
713 * small fixes to pa.ly
718 * Fixed bug that made multi-measure rest barnumber counts go wild.
719 (even more scm2int/int2scm mixups!)
721 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
723 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
728 * Remove Paper_def calls in bezier-bow.cc
730 * Remove data members of Tuplet_spanner, Volta_spanner
732 * hang_on_clef, property hangOnClef removed
734 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
735 function to determine breaking behavior.
737 * More Scheme typechecking.
739 * Be strict about the difference between strings and symbols for conversion.
741 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
744 * Partial French translation, courtesy Laurent Martelli.
746 * Small corrections in NL translation.
751 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
752 we have a longa note head. noteHeadStyle = "harmonic" is not
753 supported anymore. (for now, that is)
755 * Reference manual update. Document \properties with examples
757 * fix mudela-book --help
759 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
760 Key_item::c0_position_
762 * Clef_engraver general cleanup. Use alists (\property
763 supportedClefTypes, clefPitches) for clef types.
765 * Use progress_indication () for progress. Don't include <iostream.h> directly
766 Don't include <string.h>, <math.h> from headers.
772 * \property stemCentered (boolean): centers stem on note head. See
773 input/test/stem-centered.ly
775 * input/trip.ly, small test of lots of features.
777 * \property Staff.collisionMergeDotted: merge equal noteheads
778 with different dot count. See input/test/collision-merge-dotted.fly
782 * Don't crash if a slur does not span any notes.
784 * Volta repeats fixed.
786 * cleanup of Note_heads_engraver
788 * removed dots_i_ member of Dots
792 * Fixed cross staff slurs. It seems that cross-staff sign
798 * Fixed bug in stem code. Stem in chords works again. Small
801 * Use element properties for Staff_symbol.
803 * \property sparseTies (boolean). Only make one tie in the
804 middle for tied chords.
806 * Junked Directional_spanner, Column_info.
807 Directional_element now is element interface `Directional_element_interface'
809 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
