8 correctly when they are above the staff.
14 * Small bugfix: also do a deep copy on submusices
16 * Fixed: \autochange doesn't crash anymore.
18 * Cleanup, documentation and enforcement of smob interfaces in
19 LilyPond. We distinguish between SIMPLE_SMOBS and SMOBS (objects that
22 * Glen Prideaux lyric phrasing engraver. See
23 input/test/lyric-phrasing.ly
30 * Removed \interscoreline after the last line, prevents some
31 empty pages. (patch by Mats Bengtsson)
33 * Smobified Music, junked associated identifiers. Use Scheme list to
34 store Music_sequence. Removed const declarations from
35 Music_iterators. Added a mutable and immutable property list to
36 Music. Use music property for all Scheme values in Music. Created
37 and fixed a load of Garbage Collection bugs.
39 * Changed number font to allow automatic .mf creation.
41 * Output place of definition as \special{src:LOCATION}. See FAQ for
42 explanation how to use.
44 * Schemified Local_key_item and fixed minor bug with accidentals.
46 * new Japanese .po file.
48 * Bugfix for broken tie direction
50 * Bugfix for bar at beginning of line break
55 * Robustness fix for minimise_least_squares ()
57 * cleanups of Slur_bezier_bow, removed Bezier_bow.
59 * cleanup of Tie. Changed Tie into interface. Made ties flatter by default.
61 * changed SCM_UNDEFINED to SCM_UNSPECIFIED for return values that go
64 * changed SCM_UNSPECIFIED to SCM_EOL for undefined element
65 properties. This makes initializing list properties redundant.
67 * removed idiotic code for including tfm.[1-5] into search path.
69 * fixed problem with tuplet placement for cross staff tuplets.
73 * Small cleanups to bring down compile time and binary ensmallment.
75 * Made Lookup into a smob, and use guile alist iso. an STL map.
77 * Changed repeated music semantics for relative octave: each
78 alternative takes its inital octave from the body.

82 * Added Scarlatti sonata test file to input/
84 * kpathsea support, courtesy Carsten Block <carsten.block@gmx.de>
88 * Fixed: long standing problem in optical-illusion code.

109 * Fixed: don't invoke Hara_kiri::consider_suicide too early.
111 * Fixed: property engraver.
113 * Fixed: don't crash on multiple ties.
115 * Cleanups of Beam, should also be a little faster.
117 * Reunite properties and pointers. In implementation we make a
118 distinction between mutable and immutable properties
120 * Add {has|set}_interface () static methods to interface classes.
122 * Made Side_position_interface and Staff_symbol_interface an all
123 statics class, and stripped _interface suffix.

141 Volta_spanner changed into interface.
143 * Related cleanups for Tie, Tie_column cleanups.
145 * Made Time_signature, Single_malt_grouping_item, Script_column,
146 Chord_name, Dot_column, Breathing_sign, Key_item type into interface.
148 * Removed const declaration from callback arguments.
150 * Pagebreak support. See input/test/between-systems.ly
152 * Fixed a problem with accidentals in combination with
153 non-nil key signatures.
158 * Use callbacks for augmentation dot positioning.
160 * Removed types Note_head and Rest
162 * Cleanup of slur.cc: use common reference points in a sane manner.
167 * Corrected text sizes in paper*.ly (Mats Bengtsson)
172 * Dots, Collision, Rest_collision removed as separate Score_element type.
174 * Stem and Note_column accept only one rest.
176 * Use offset callback in Stem to resolve rest/beam collisions.

196 * Bugfix: translate volta spanner at start of line.
198 * Changed directional_element() calls to instantiations
199 of Directional_element_interface.
201 * Removed Dynamic_line_spanner, and cleaned up Dynamic_engraver.
203 * Removed Staff_info type. Information about columns is now transferred
204 via currentMusicalColumn and currentCommandColumn.
210 * Made slur attachment position user settable; properties:
211 slurBeginAttachment slurEndAttachment, values: 'head 'stem
212 'along-side-stem. See input/test/slur-attachment.ly and ophee-slurs.ly.
214 * Fixed slur attachment positions, added missing rule and use simple
215 default starting positions for attachments.
217 * Started rewrite of slur ending code, interstaff slurs are broken for
220 * Fixed download URL of the webpage.
222 * Moved direction.cc to flower/.
227 * Lyrics centered on notehead.
229 * Various bugfixes hyphen-spanner.

247 * Bugfix: use deep copies for resetting keys.
249 * Assorted typing erors in procedure names in ly/engraver.ly
254 * Made callbacks from Score_element::before_line_breaking() and
255 Score_element::after_line_breaking()
257 * Fixed website; backlinks should work again.
259 * Removed --ignore-version option. Added --verbose option.
269 * Junk int_identifier, real_identifier. Merged Midi_def_identifier and
270 Paper_def_identifier.
272 * Fixed bug with spanning barlines in combination with Hara-Kiri staffs.
274 * Cleaned up Text_item, Hyphen_spanner, Lyric_extender and
275 Sustain_pedal and reduced them to an Score_element interface (they are
276 no longer Score_element derived types).
278 * Some instances of brew_molecule routines have moved out of
279 Score_element, and are now called scheme_molecule.
281 * Moved lots of parameters from ly/params.ly to ly/engraver.ly
286 * Removed String_identifier, and use the type system of GUILE instead.
288 * Fixed \key PITCH MODALITY syntax. The modality argument is now
289 mandatory, a rule in convert-mudela has been added.
291 * Cleaned up buildscripts/ directory: removed obsolete scripts.
293 * Use Scheme_hash_table for identifier Scopes. Scheme_hash_table is
294 based on STL and should be faster than hash_table.
300 * Fixed scm_un/protect_object for guile-1.3.4 and 1.3.5 snapshots,
301 in the process reduced number of protect/unprotect calls. With
302 guile-1.3.5 snapshot, memory usage has decreased by 1/5th, now
303 just 10% above the 1.2 level. Also, Lily's a bit faster.
305 * Fixed make diff bug in stepmake to be able to make this diff :-)
310 * Rewrote key sig support. Now key signature can also be controlled
311 by setting keySignature and localKeySignature properties, eg.
313 \property keySignature = #'((2 . -1) ( 4 . -1) (6 . -1))
315 sets a key signature of `es ges bes' (an unusual key signature).
317 Keys are internally represented as transpositions of the c-major
318 scale. Printing the key signature for a scale is done by filtering out
319 all non-natural accidentals.
321 * Removed support for \keysignature, and \key something \minor; Newkey
327 * Fixed pedal items (hw)
329 * Changed configure option tex-tmfdir to tmf-path now accepting multiple
330 tfm directories. Automated links to cmr and amstex tfm font directories.
332 * Replaced one scm_assoc () u-turn slipped through jcn1
334 * various GUILE 1.3.5 compile fixes
336 * Added `Ped' as a compound symbol font and removed silly scheme kerning.
338 * Replaced some scheme assoc u-turns with scm_assoc ()
340 * Ran po-update (mostly because of new ja contribution).
345 * Cleaned-up scheme list to text conversion for Chord_name and
346 fixed horizontal kerning.
348 * Added examples for american (slashed o) and jazz (black triangle),
349 see input/test/{american-chords.ly,jazz-chords.ly}
351 * Made guile-1.3.5 compile fixes
356 * Fixed typo in Dots::do_brew_molecule (); this fixes the disappearing
359 * Rewrote key signature administration; now Scheme is used; Octave and
360 Key have been junked in favor of Newkey.
362 * japanese .po file included (thanks, Japanese team!)
367 * Fixed several forgotten molecule-callbacks
369 * Fixed first clef in score; now F clefs are also possible.
374 * Updated FAQ with two useful GDB macros.
376 * Several fixes in the documentation.
381 * Made (dutch) po-update
386 * Molecules are now generated via callbacks exclusively; most calls to
387 set_elt_property ("transparent", SCM_BOOL_T) have been replaced by suicide().
392 * Experimental property collapse for most score-elements. (notable
393 exceptions: Scripts, pedals). Change all Score_element constructors to
394 take a basic-property list. The suffix of a property list may be
395 shared by several score-elements, for instance all default G-clefs in
396 a score share the following settings
399 (break-align-symbol . Clef_item)
400 (visibility-lambda . ,begin-of-line-visible)
402 This should reduce memory usage further.
404 * Magically fixed the disappearing Lyrics problem.
406 * Removed used_b_ field from Score_element.
408 * Massive search-replace patch: store pointers and properties
409 separately, in preparation of property collapse.
415 * Bugfix: don't crash on tuplet spanners that don't contain any notes.
417 * Cleanup of Dimension_cache: removed a few redundant
418 fields. Slightly lower memory usage (32 bytes per
419 score-element). Dimension_cache is now a `dumb' struct again.
421 * Add array index to priority field of text scripts to ensure that
422 order is unique, and sensible.
424 * Added an element count statistic.
429 * russian.po (thank you, August.)
431 * Small cleanups in Molecule interface
433 * Spacing related elements perform suicide after calculating
434 distances. This saves a some memory, approximately 2 to 5 % ?
436 * Small cleanups in line breaking: Paper_column stores springs and
437 rods in only one place now. All fields relating to energy have been
440 * Don't generate all output Scheme in memory, but evaluate to output
441 file immediately. This will reduce memory usage a little.
443 * Use STL's map for Dictionary template
445 * Substitute pointers on element properties of the root Line_of_score
448 * Added toplevel doc target, to support building doc with --srcdir
450 * Removed cygwin build stuff; updated versions at:
452 http://appel.dyndns.org/lilypond/gnu-windows/cross
454 * Fixed lily.scm to handle incipits (thanks, Mats)
460 * Made bugfix in smob handling: delete the C-part of freed smobs and
461 be honest about amount of allocation and deletion, so that GUILE
462 doesn't overestimate the amount of memory available.
464 * Faq update: nicer blank note paper, courtesy Mats Bengtsson.
466 * Bugfix: don't crash on durations that are not a power of 2.
468 * Build manpages during `make all'
470 * Bugfix: don't do absolute comparisons in Polynomial::clean ().
472 * Bugfix: set visibility-lambda for key signature created by
473 createKeyOnClefChange. Fixes disappearing key signatures.
475 * Bugfix: make System_start_delimiter of bar-line type invisible when
476 it spans only one staff.
481 * Item cleanups. Copying items and rearranging pointers are done in
482 separate passes, which makes the code cleaner. This fixes a problem
483 with some items not disappearing from hara-kiri staffs.
485 * Use Scheme for Key_item data members.
487 * Don't use regex in chord-names.scm under windows; hybrid chordnames
488 user+calculated will be partly broken.
493 * Junked Shift_tuple from collision; Now it uses SCM.
495 * Bugfix of documentation and test-file of tuplet.
497 * Bugfix type string of repeated music is copied. This fixes declared
500 * Junked various cruft from lily.scm
502 * Use interfaces symbols instead of C++ class-name for assigning generic
505 * Junked Dictionary from Piano_pedal_engraver and
506 Piano_pedal_performer.
508 * Introduced boolean element property no-spacing-rods: ignore this
509 item for hard constraints.
511 * Bugfix: added sanitised TeX fragment in faq.texi
513 * Bugfix: merge equal Bar_reqs
518 * Small fixes for \cresc and \endcresc
520 * Release properties of unbroken spanners & items after doing
521 handle_broken_smobs (); should conserve a little memory.
523 * Fixed handling of orphaned score-elements. Any element that does
524 not have its Line_of_score as a ancestor in both directions, is silently
525 removed from the output. This guarantees that programming errors
526 don't result in coredumps from Dimension_cache::common_refpoint ():
527 element->line_l () is always a common reference point.
529 * Bugfix: set visibility-lambda of clef and octavation-8 explicitly
530 for default case. Now the octavation 8 is not printed at every
536 * Changed noteHeadStyle properties to symbols, for example
537 \property Voice.noteHeadStyle = #'cross
542 * Rewrite of chord-name production in scheme. There are two major styles
543 now, banter and american. To get american style, use
545 \property ChordNames.chordNameStyle = "american"
547 Most anything should be possible now. See input/test/american-chords.ly
549 * Added isinf check to configure.in, and isinf macro from guile to
550 bezier.cc; solaris has no isinf ().
552 * Fixed star-spangled-banner with not-so-nice \bar "|." fix. Almost
555 * Added output property to regression test.
557 * Fixed warning of creating existing outdir.
559 * Added `Mark' interface to text-items that are marks (thanks, HW).
566 * Corrected glossary.tely
568 * Corrected \mark font handling. feta-nummer font only of the
569 string is all numeric.
571 * Implemented noteHeadStyle lookup in Guile. Reintroduced the style
572 "harmonic" and added "baroque" (normal note shapes except for
573 brevis and longa which are square).
575 * Simplified ly2dvi using the power of the geometry package.
577 * Improved heuristic size calculation of TeX macros. Handles e.g.
578 "\\u{a}", "\\"{o}" and "\\^{u}" correctly.
583 * Bugfix: don't hang on zero-duration.
585 * Various glossary updates (thanks, Christian)
593 * Drastically reduced vertical space used by headers/footers, when using
594 ly2dvi. See input/test/fill-a4.ly.
596 * Fixed bug with colons appearing on repeat span-bars.
598 * Added Bar_number_engraver to standard Score context
600 * Construct octavation scripts in the clef-engraver; this fixes the
601 hara-kiri + clef8 problem
609 * Fixed chord-name customisation and made small chord-name build fixes.
611 * Accidentals with chord-names smaller and as superscript.
613 * Do some extra footify (works only once) while making html docs.
618 * Debian patch (Thanks Anthony)
620 * Rewrote Bar_number_engraver and Mark_engraver and removed
621 Bar_script_engraver as baseclass. Both Bar_number_engraver and
622 Mark_engraver are simpler and more robust.
624 * Fixed precedence of \property verticalDirection and dynamicDirection
626 * Fixed keys without barlines
628 * Fixed StaffGroups: removing `\consistsend "Axis_group_engraver"'
629 puts alignment in function again
631 * Fixed StaffGroup + GrandStaff combination.
633 * Music is now mandatory as the first thing in a \score{} block
640 * Implemented una-chorda and sostenuto piano pedals in performer and engraver.
642 * Added Properties textScriptWordSpace and chordNameWordSpace.
644 * Junked old lyrics in star-spangled-banner.
646 * Added a Piano_pedal_engraver.
648 * Removed some empty files.
650 * Created piano pedal symbols: * - . P e d.
652 * Fixed ps-to-pfa.py to handle multiple unfills.
654 * Moved accordion symbols out of feta-script to end of font.
656 * Bugfix: don't create tfm's, pfa's etc of feta-test fonts.
658 * Fixed blot_diameter for small resolutions.
663 * Put global element list into Line_of_score, instead of
664 Paper_score. post processing (the stage after line breaking) is now
665 truly done per-system, and we got rid of an ugly hack to get font
668 * Bugfix: set the group-interface of System_start_delimiter.
670 * Cleanups of Break_algorithm and derived classes, Move
671 broken_col_range () to Line_of_score, remove Paper_score::col_l_arr_
673 * Bugfix for accordion symbols.
675 * Various patches to prevent crashing when do_brew_molecule gets
676 called before after_line_breaking (). This was a problem in Spanner
685 * Made a quick try at piano pedal performer, damper pedal only.
687 * mf/feta-accordion.mf: Fixed strange turning paths.
689 * mf/feta-beugel.mf: Fixed infinity errors.
691 * Use a more discriptive name for windows setup.zip.
693 * mf/GNUmakefile: Have logs as last target, so that normally, they're
696 * stepmake/stepmake/metafont-rules.make: Don't remove the .log files.
697 The logs are a target, removing them retriggers make.
699 * stepmake/stepmake/metapost-rules.make: Remove the correct log and tfm
700 files, ie the ones that clutter the source directory, not the target logs.
702 * Windows distribution: faked symlink for cmtfm. Setup.zip should now be
703 standalone; ie, no need for Cygnus' usertools anymore.
708 * Documentation/ntweb: Updated angels.ly to match current syntax.
709 Also updated index.texi.
714 * Change all occurances of Staff_margin_engraver to
715 Instrument_name_engraver, add a convert-mudela rule
717 * Change status == busy assert into programming error
725 * Lots of fixes to windows distribution scripts.
727 * Added configuration features --program-prefix, --program suffix.
729 * lily/my-lily-parser.cc (get_chord): Bugfix, don't use deleted pitch.
730 This fixes inversions c/g and bass additions d/+c on chords.
735 * Avoid that xxxXXXVerticalExtent is used for empty HaraKiriStaff
741 * Debian patches (thanks Anthony!)
743 * Use symbols for prefatory matter spacing. Do not use the typename
744 for looking up item pairs in the table, but read element property
747 * Instrument_name_engraver, uses break alignment instead of
750 * System_start_delimiter_engraver, System_start_delimiter, uses a
751 spanner for the braces/brackets at the left of the system. Remove all
752 old Span_score_bar engravers.
754 * Removed Base_span_bar_engraver::use_prority_b_, and moved
755 Base_span_bar_engraver into Span_bar_engraver.
760 * mutopia/Coriolan/violino-2.ly: Bugfix: wrong pitch.
762 * input/test: Removed stale AutoStaffSwitch examples.
764 * mutopia/E.Satie: Fixed gnossiene-4, doing \autochange. Removed
765 stale copy of gnossiene-4.
767 * buildscripts/make-cygwin-cross.sh: Made some small .zip package fixes.
769 * make/lilypond.spec.in: Made some bugfixes for _prefix, preparations
770 for cross-building to Cygwin.
772 * buildscripts/make-cygwin-cross.sh: Now using rpm packages.
777 * added \property XXXMinimumVerticalExtent, \property XXXExtraVerticalExtent
779 * New_chord_tremolo_engraver: make tremolo beams from
781 \repeat "tremolo" NUMBER <Music-expression>
783 Removed support for "old-style" tremolos.
785 * Add a convert-mudela function for the conversion "\key A;" to "\key a;
787 * Read \property measurePosition within the engraver code, instead of
788 looking up the Timing_translator.
790 * star-spangled-banner.ly: add Bar_engraver to LyricsVoice
792 * Changed all .fly and .sly files to .ly files. Propose to dump .fly
801 * buildscripts/mf-to-table.py: feta dep files are now opened with write
802 binary option. This avoids carriage return linefeed problems and
803 windows while not affecting unix.
805 * Documentation/hacking.texi: Fixed a texinfo syntax error
807 * stepmake/bin/package-zip32.sh: Fixed or Removed some legacy, 1.2.x,
810 * Documentation/ntweb/index.texi: Fixed broken links, added 1.3.39 links.
815 * Glossary updates by Christian Mondrup.
817 * Bugfix: use generic properties in lyrics too. This fixes the
818 \property textStyle for lyrics.
820 * Score_element::preset_extent(), used by \property
821 XXXVerticalExtent, so hard code the size of a vertical group.
823 * Don't fix up reference points for originals of broken
824 spanners. Fixes spurious "orphaned score-element" warnings.
826 * buildscripts/make-cygwin-cross.sh: Use rx-1.5 instead of regex (Jeffrey).
828 * scm/lily.scm: Fixed check for Windows: by default don't use scm regex.
830 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: Significantly smaller
833 * buildscripts/make-cygwin-cross.sh: Compile native package GNU regex,
834 which should fix Windows problems with guile. Also added input directory
837 * stepmake/aclocal.m4: Added decent checking for version of guile, and
838 fixed warning message.
840 * lily/lexer.ll (My_lily_lexer): Bugfix: lookup chordmodifiers in the
841 chord-modifier table (not in the pitch list).
849 * General cleanups of My_lily_parser.
851 * Start of a Chord_tremolo_iterator for the `\repeat 4 "tremolo"'
854 * Moved Score_element::do_space_processing out of the dependency
857 * Use Scheme for notename tables. Removed uppercase letters for low
858 octave notes. Removed Notename_table.
860 * Fixed core dump with declared "\key ; "
862 * Extra robustness warning for Side_position_interface::aligned_on_self ()
864 * Extra robustness: make sure that first and last columns are breakable.
869 * stepmake/aclocal.m4: Added support for cross-compiling with guile.
871 * buildscripts/make-cygwin-cross.sh: A try at dropping cygwin1.dll
872 dependency by using mingw. Compiling guile is too much to ask
873 for mingw, though. Also:
874 - rename python scripts .py (request from Alain)
875 - install native packages under their own, separate root. (Alain)
877 * lily.scm: Don't use regex module when running on
880 * lily/staff-margin-engraver.cc (acknowledge_element): If
881 possible, hang y-axis of margin script to span-bar. This fixes
882 vertical placement of margin scripts attached to staff groups.
884 * help2man-rules.make: Fixes for generating manpages by copying
885 and for building using --scrdir.
887 * stepmake/stepmake/generic-targets.make: Preserve date stamp of
888 config.h, version.hh files file when copying.
890 * buildscripts/make-cygwin-cross.sh: made number of fixes:
891 - add `Cygnus/' prefix to directories in .zip-file too.
893 - don't link to cygwin1.dll
895 * stepmake/stepmake/install-targets.make: bugfix, don't fail if directory
896 is not emty when uninstalling.
898 * stepmake/stepmake/generic-targets.make: added man target.
900 * buildscripts/make-cygwin-cross.sh: new script for cross-building cygwin
901 development tools and lilypond executable.
903 * Documentation/ntweb/lilypond-manpages.patch: provide pre-built
904 manpages, so that make doesn't fail on help2man trying to execute
905 a GNU/windows executable.
907 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: new patch for
910 * flower/libc-extension.cc (memmem): cygwin compile fix.
918 * (generic-property.scm) added \property tieDash to set dashing on
921 * Removed ly_eval_str(), we should use scm_eval (Scm_object).
923 * Removed scm_to_array (), array_to_scm (), associated junk. Reverted
924 undocumented .29 patch that made Bezier::control_ into an
925 Array<Offset>. Added some comments documenting the reasons for the
928 * Revert generic-property.scm of .37 fix, fix the real problem in
929 property-engraver.cc: use the right symbol to check if element
930 property is already set.
935 * Fixed srcdir build, so that you can do:
937 tar xzf releases/lilypond-x.y.z
940 ../lilypond-x.y.z/configure
943 as with any other gnu package. All build output goes to <build>/out.
945 * Changed and fixed use of different configurations, and different output
946 directories. Finally, you can use different configurations alongside
947 eachother. From make/stepmake.make:
949 # Use alternate configurations alongside eachother:
951 # ./configure --enable-configsuffix=debug
954 # uses config-debug.make and config-debug.h; output goes to out-debug.
957 # Use same configuration, but different output directory:
961 # uses config.make and config.h; output goes to out-www.
965 * Fixed performance of (de)crescendi.
967 * Better documentation for arithmetic_multiplier and arithmetic_basicspace
970 * Added instrument-equaliser for MIDI output, see scm/midi.scm, and
971 properties midiMinimumVolume, midiMaximumVolume, ranges [0,1].
973 * Changed absolute midi volume settings into factor of full scale.
975 * Fixed another dynamic-line-spanner bug, it gets hairy.
977 * Added warning for spanners that are not fully contained in parent spanner.
985 * Abstract Align_element into Align_interface. Removed
986 Axis_align_{item,spanner}, Align_element, Super_element, all multiple
987 inheritance in the backend.
989 * new Gade score, INSTALL.texi fixes (thanks, Mats)
991 * Removed Item::hpos_f (), Score_element::{get,set}_real ()
993 * comments detailing properties for Axis_group_interface,
994 Side_position_interface, Score_element, Item and Spanner
999 * Fixed vertical dimensions of elements in dynamic line spanner by adding
1000 axis-group to dynamic line spanner.
1002 * Bugfix: line-spanner lasts always full duration of (de)crescendi.
1004 * Bugfix: broken (de)crescendi on a dynamic-line-spanner.
1006 * Bugfix: compilation dynamic-engraver.
1008 * Added and updated a faq about postscript and ghostscript.
1010 * Fixed order of slurVerticalDirection verticalDirection in
1011 generic-property.scm. Similar fixes for Stem, Tie, etc.
1013 * Added a Text_engraver to GraceContext. Maybe it was removed on
1014 purpose: scripts on grace notes seem broken, they appear on the
1017 * Bugfix: volume effect of (de)crescendi was sometimes wrong way round.
1024 * textEmptyDimension changed into textNonEmpty, default: off,
1025 ie. texts don't occupy space.
1027 * Use STL map for Lookup::lookup_p_tab_p_
1029 * Abstracted Axis_group_element into Axis_group_interface, and removed
1030 Axis_group_element. This eliminates some multiple inheritance in the
1036 * Added minimum-space property to Side_position_interface. Used in
1037 positioning of Volta_spanner: voltaMinimumSpace.
1039 * Fixed and cleaned-up volta-spanner.
1041 * Moved directional-element.cc -> directional-element-interface.cc
1043 * Renamed all `process_requests' to `process_music', which fixes
1046 * Fixed dimensions (more x-y interchanges) of brace, bracket and
1049 * Half-assed fix to get similar vertical placement of orphaned vs.
1050 line-spanned dynamic elements.
1052 * Added property bracketCollapseHeight: the minimal size of a staff bracket
1053 that will be typeset. Smaller brackets will not be displayed. This
1054 fixes the (in 1.3.x reintroduced) funny duck-beak-bracket-bug (sorry).
1056 * Removed some dissonant chords from Coriolan
1061 * Removed Documentation/programmer directory
1066 * Small enhancements to Staff_margin_engraver:
1067 - by default, the marginScript left aligns the text
1068 - to set the text style, use property marginScriptTextStyle
1069 - to change the alignment, use property marginScriptHorizontalAlignment
1070 (centred and right alignment require manual padding settings).
1072 * Print a friendly message if the manual pages failed to build.
1074 * Bugfix: dynamicDirection now overrides verticalDirection setting.
1076 * Warning messages and nl.po
1078 * Fixed vertical alignment for all dynamic items and (reluctantly)
1079 reinstated old directional behaviour for orphaned dynamics.
1081 * Finished maximumRestCount property.
1088 * Print key without setting key, syntax "\key ;". General cleanups of
1091 * Add paragraph tags in HTML output of mudela-book. Music fragment
1092 don't run into the text anymore.
1094 * Bugfix: don't align the first line of text. (Lookup::text ()).
1096 * Abstract away data members of Axis_group_element, Align_element
1102 * Added helpful properties instrumentScriptPadding/instrScriptPadding for
1103 Staff_margin_engraver.
1105 * Removed some empty files, substituted (c) 1999 occurrences.
1107 * Added \property maximumRestCount. It will prevent showing (or actually:
1108 moving in case of a collision) more than maximumRestCount similar rests.
1111 * Rewrote Staff_margin_engraver. Staff margin texts now hang on a new
1112 breakable item: Left_edge_item.
1114 * Fixed vertical alignment for dynamic elements. Orphaned dynamic items
1115 (not supported by a Dynamic_line_spanner) still collide with Staff,
1116 although they now have staff support, which was supposed to fix this.
1118 * Fixed Staff_margin_engraver for "instrument", "instr" is still broken.
1120 * Dynamic elements are only put in a Dynamic_line_spanner if there
1121 actually is more than one adjacent note-column with a dynamic.
1122 This breaks the fine looks of all dynamics, again :-)
1133 * Experiment: use STL map for Scheme_hash_table; Is there a speedup?
1135 * Bugfix: print brace iso. bracket for Piano / GrandStaff
1137 * Change naming: change do_post_processsing into after_line_breaking,
1138 do_pre_processsing into before_line_breaking and do_process_requests
1139 into do_process_music.
1141 * Bugfix in hash-table.hh: do quadratic probing, and not cubic probing.
1143 * Display property name for type error.
1145 * Cleanups for Dynamic_engraver and Dynamic_line_spanner.
1147 * Warn if last column in score is musical. Helps catch programming errors.
1149 * Spanner::spanned_drul_ now is private.
1151 * Rewrote some bar code: moved molecule functions out of Lookup.
1156 * Embedded newlines in text items are now allowed. This helps avoiding
1157 TeX-hacking in some cases. See input/test/coriolan-margin.ly
1159 * Fixed stupid x-y interchange bug for staff-bracket. This fixes
1160 placement of staff-brackets.
1162 * Fixed bracket/arch-thickness interchange bug, and made bracket a bit
1165 * Fixed slur/bezier-beautiful name mismatch. This should fix the steep
1166 slurs that were apparently reintroduced in 1.3.29.
1168 * Made some small fixes to Coriolan.
1170 * Removed duplicate lily/output-property-engraver.hh.
1172 * Removed optional use of vanilla spanner in Dynamic_engraver.
1174 * Fixed (measured) tremolo for Stem and Beam. Merged declarations
1175 stem-engraver.hh and chord-tremolo-engraver.hh into their .cc
1176 implementation file. Also fixed looks of Chord tremolo, input and
1177 implementation is still ugly.
1179 * Added *.yy and *.ll to TAGS, to that tags-find-replace doesn't omit
1185 * Fixed \specialkey and \normalkey. Updated documentation.
1192 * Fixed and cleaned-up Dynamic_engraver. Optionionally uses vanilla
1193 spanner instead of Dynamic_line_spanner.
1195 * Made gcc-2.95 compile fix in libc-extension.
1197 * Various fixes to Coriolan, score starts to look acceptable.
1199 * Moved optional text of crescendo into Crescendo spanner. Fixed horizontal
1200 and vertical alignment of dynamics.
1202 * Added new text crescendo spanners to Coriolan and made some fixes.
1203 If you're using timidity, use the -EO option to prevent notes get
1204 stuck. I'm not sure whose fault this is, Lily's MIDI output may be
1205 stretching the standard a bit.
1207 * Adjacent dynamic markings are now grouped on a horizontal line, but it's
1208 not perfect yet: they're always below the staff and no horizontal spacing
1209 is done. Also, character metrics of dynamics are still not used.
1210 See: input/test/crescendi.ly and input/test/dyn-line.ly
1212 * Cleaned up Span_dynamic_performer.
1219 * Fixed the page layout, reintroducing space for the header and
1220 trying to keep piece titles on the same page as the piece.
1221 The header and footer can now contain several lines.
1226 * Lily now also performs crescendi and decrescendi in MIDI output:
1227 Span_dynamic_performer in a slightly crappy way.
1229 * Added preliminary support for crescendi/decrescendi other than `hairpins',
1230 eg: `cresc. poco `a poco -- -- --'
1232 * Made MIDI tie performance fix.
1237 * Lily now performs absolute dynamics in MIDI output.
1239 * Included David's comments on opus47 in TODO.
1244 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
1245 fixes and remainder french horn-1,2; trombone-1,2;
1246 fagotto-1,2; timpani; and several fixes.
1251 * Remove some old doco from programmer/ and put on personal homepage.
1253 * Removed union-find from flower library.
1255 * Only quantise tie horizontal part inside the staff.
1262 * Report type errors for \property. Helps with converting 1.2 input
1264 * Use Scheme for Align_element; fixed graceAlignPosition
1265 and removed \property alignmentReference in the process.
1267 * Use generic properties for lyrics too. This fixes \property
1271 * Add relative distance for constraints between non-column items.
1273 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
1274 increased automatically.
1276 * Translators now only change properties of their own context. This
1277 removes the 2nd argument to Translator::get_property()
1279 * Bugfix for Metapost mode
1284 * Updates of glossary (Christian Mondrup)
1286 * Bugfix with bar number placement
1288 * Moved links to bibliography/ and misc/ to main index.
1293 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
1294 Slurs are now calculated just once.
1296 * Bezier_bow gets constants from paper. Still no sensible solution for
1297 magic asymmetry gradient step constants.
1299 * Reinstantiated tangent-controls, more flexible than ever. You can choose
1300 between area asymmetry and tangent-controls. My guess is, tangent controls
1301 will be junked in 1.3.30.
1303 * Slur area: only look at x-gradient.
1305 * Added credits for some symbols of as5/9 fonts.
1307 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
1309 * Bugfix: midi2ly put out recent version (ugh).
1314 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
1317 * Removed Gade score. To appear (shortly?) on Mutopia.
1319 * Make Bar_script_engraver look for typeVisibilityFunction (eg
1320 property barNumberVisibilityFunction). Changed the names of the Scheme
1321 functions to be understandable. See input/test/bar-script-visibility.ly
1323 * rewrite of class Molecule. It has now reached the ultimate quality
1324 plateau. All molecule data is now shared.
1329 * Update of the glossary by Christian Mondrup
1331 * Moved horn-concerto-3 out of tarball to private website, removed
1332 W.A.Mozart subdirectory.
1337 * Bugfix: don't make giant ties if the horizontal part of tie is near
1340 * Small optimizations to be a little more careful with mem usage.
1342 * Website change: put all examples in one directory.
1344 * Removed Atom as a separate type. Now use SCM, and since we use
1345 function composition, Atoms are immutable, so they don't have to be
1346 copied. This makes life easier, hopefully this is quicker and uses
1352 * Bezier_bow: minimise_enclosed_area
1360 * Tuplet-spanner slope calculation now looks better on tupletted rests
1361 (patch courtesy Laurent Martelli)
1363 * Bugfix (Staff_performer::new_instrument_str ()) check type of
1364 \property "instrument"
1366 * New mechanism for breaking lines: do not copy & prune the element
1367 property list separately, but combine these steps. Dramatically
1368 reduces memory usage for large scores.
1375 * Bugfix: font used in volta-spanner calculation.
1377 * Added simple selection list to webpage, inspired by sawmill.
1379 * Devised kludge for ascii 5 character font pitches.
1381 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
1386 * Plug memory leaks related to Moment:
1387 - Spacing_engraver::do_pre_move_processing ()
1388 - make_rational ()/make-rational
1389 - Paper_column::Paper_column ()
1391 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
1393 * Plug memory leak in Score_engraver::set_columns ()
1395 * Plug memory leak in Scheme_hash_table::set()
1397 * Plug memory leak in Score_element::molecule_extent ()
1399 * Bugfix: don't crash if a slur doesn't span anything.
1401 * Bugfix: don't crash if doing beams without a staff symbol.
1403 * Generic element property setting:
1405 \outputproperty #predicate #'symbol = #value
1407 Will set the element property symbol to value, for any elements that
1408 return true for PREDICATE. This allows you to virtually tweak *ANY*
1409 property of the output. Example in input/test/generic-output-property.ly
1414 * lilypond as as2ly: --help and --version to stdout. Regular identify
1415 to stderr. This fixes help2man's manpage generation.
1417 * configure: substitute full path for perl and guile in scripts.
1419 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
1421 * Bugfix: default font now user settable
1423 * as2text: handle plain ascii font, read from stdin, you can now do:
1425 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
1430 * Bugfix: second half of broken ties now are displayed again.
1432 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
1433 it horizontally on the clef.
1435 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
1437 * Bugfix: unbroken repeat barlines now work, eg. |:
1439 * Added Request_iterator to make more flexible constructions possible.
1443 * as2text: catch missing font/character errors, added default font, set text.
1445 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
1447 * Ascii output, minimal support:
1448 - AsciiScript Fonts: mf/*.af
1449 - Init files: ly/*-as.*ly
1450 - AsciiScript translation to text: scripts/as2text.scm
1451 - input/test/as.fly input/test/as1.fly
1452 - Output support: lily/lily.scm
1454 lilypond -f as -i init-as.fly input/test/as.fly
1460 * The horizontal part of ties will avoid collision with staff lines.
1462 * Plugged memory leak: don't protect Atom function.
1464 * Lookup cleanups. Made lots of functions static. Moved some code out
1472 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
1473 does not delete any of the file_ly*.tex.
1475 * Added header and footer support in ly2dvi.py
1480 * Added a ROADMAP file explaining the source directory layout.
1482 * Minor tweak in the feta 6 and 9 numeral

1488 * Updated the webpage to be a little more chatty.
1490 * Small Local_key_engraver optimization: only lookup timing engraver once.
1492 * Fixed dashed slurs
1494 * Rewrite of Slur code. Be much more picky about slur shapes. We try
1495 to offset the slur instead of bending it too much
1497 * Look at stem directions for tie direction.
1499 * Compound multimeasure rests. Put measures_i_ variable in an element
1500 property. Made the symbol a lot wider.
1502 * Time signature small cleanups.
1507 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
1510 * Breathing marks now have a direction by default.
1512 * Do set generic script properties.
1514 * Also put tuplet brackets under notes.
1516 * Score_element_info: only store origin of element, but not the path
1517 to parent translators. Saves a little memory, and removes some complexity.
1523 * Autobeaming in time sigs that don't have 1/4 beats fixed.
1525 * (De)crescendi should now work. (Thanks Michael)
1527 * Better error reporting for conflicting time signatures.
1529 * Line_number_engraver: output locations of note head
1530 definitions. Very handy when entering complicated scores.
1532 * Rewrote multi measure rest support: now they are entered as spanners
1533 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
1535 { \commandspanrequest \start "rest"
1537 \commandspanrequest \stop "rest"
1540 * Removed support of percent style repetitions.
1542 * Put texts outside the staff.
1546 * Getopt bugfix: don't assert on certain errors.
1548 * ly2dvi: Remove unnecessary space for the page headers.
1550 * Bugfix convert-mudela
1555 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
1558 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
1559 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
1560 \property tupletInvisible will stop all tuplet spanner creation.
1562 * Don't go berserk if tuplet spanner is on only one column.
1564 * Use SCMs & Smobs for Molecules & atoms. This uses less
1565 scm_(un)protect_object () calls, so the output stage should be faster.
1567 * Added \property tupletSpannerDuration, to make multiple tuplet signs
1570 * Some programming Errors in spacing are now caught. Lily does not
1571 hang when encountering degenerate springs.
1573 * Allow beams to start and end over rests
1577 * Fix disappearing clefs when clefs are not printed with a barline.
1582 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
1583 input/test/beam-control.fly
1584 * Added \context Voice to .fly and .sly; the default \context Staff is almost
1585 never what you expect
1586 * Fixed decision for .sly/.fly in lilypond-mode.
1591 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
1592 Cleanup mf-to-table.py
1594 * Fixed embarassing slur bug.
1599 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
1604 * lilypond-mode.el for emacs supersedes mudela-mode.el
1606 * Tuplet spanners don't collide with encompassing notes.
1608 * Gobbled Adobe parseAFM* code, for future use.
1610 * Big 1999 to 2000 search/replace.
1612 * Big interline to staff_space search/replace for mf files.
1614 * Removed Bow class, and split code into Tie and Slur
1616 * Don't put scripts on grace notes.
1618 * Font_metric uses SCM for name field.
1620 * Various compilation fixes.
1625 * Bugfix: beams with less than one (visible) stem
1627 * small fixes to pa.ly
1632 * Fixed bug that made multi-measure rest barnumber counts go wild.
1633 (even more scm2int/int2scm mixups!)
1635 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
1637 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
1642 * Remove Paper_def calls in bezier-bow.cc
1644 * Remove data members of Tuplet_spanner, Volta_spanner
1646 * hang_on_clef, property hangOnClef removed
1648 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
1649 function to determine breaking behavior.
1651 * More Scheme typechecking.
1653 * Be strict about the difference between strings and symbols for conversion.
1655 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
1658 * Partial French translation, courtesy Laurent Martelli.
1660 * Small corrections in NL translation.
1665 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
1666 we have a longa note head. noteHeadStyle = "harmonic" is not
1667 supported anymore. (for now, that is)
1669 * Reference manual update. Document \properties with examples
1671 * fix mudela-book --help
1673 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
1674 Key_item::c0_position_
1676 * Clef_engraver general cleanup. Use alists (\property
1677 supportedClefTypes, clefPitches) for clef types.
1679 * Use progress_indication () for progress. Don't include <iostream.h> directly
1680 Don't include <string.h>, <math.h> from headers.
1686 * \property stemCentered (boolean): centers stem on note head. See
1687 input/test/stem-centered.ly
1689 * input/trip.ly, small test of lots of features.
1691 * \property Staff.collisionMergeDotted: merge equal noteheads
1692 with different dot count. See input/test/collision-merge-dotted.fly
1694 * Dotted rest bugfix
1696 * Don't crash if a slur does not span any notes.
1698 * Volta repeats fixed.
1700 * cleanup of Note_heads_engraver
1702 * removed dots_i_ member of Dots
1706 * Fixed cross staff slurs. It seems that cross-staff sign
1712 * Fixed bug in stem code. Stem in chords works again. Small
1715 * Use element properties for Staff_symbol.
1717 * \property sparseTies (boolean). Only make one tie in the
1718 middle for tied chords.
1720 * Junked Directional_spanner, Column_info.
1721 Directional_element now is element interface `Directional_element_interface'
1723 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
