2 ++ b/CHANGES Wed May 31 00:06:33 2000
7 * Updated FAQ with two useful GDB macros.
9 * Several fixes in the documentation.
16 * Made (dutch) po-update
21 * Molecules are now generated via callbacks exclusively; most calls to
22 set_elt_property ("transparent) have been replaced by suicide().
27 * Experimental property collapse for most score-elements. (notable
28 exceptions: Scripts, pedals). Change all Score_element constructors to
29 take a basic-property list. The suffix of a property list may be
30 shared by several score-elements, for instance all default G-clefs in
31 a score share the following settings
34 (break-align-symbol . Clef_item)
35 (visibility-lambda . ,begin-of-line-visible)
37 This should reduce memory usage further.
39 * Magically fixed the disappearing Lyrics problem.
41 * Removed used_b_ field from Score_element.
43 * Massive search-replace patch: store pointers and properties
44 separately, in preparation of property collapse.
50 * Bugfix: don't crash on tuplet spanners that don't contain any notes.
52 * Cleanup of Dimension_cache: removed a few redundant
53 fields. Slightly lower memory usage (32 bytes per
54 score-element). Dimension_cache is now a `dumb' struct again.
56 * Add array index to priority field of text scripts to ensure that
57 order is unique, and sensible.
59 * Added an element count statistic.
64 * russian.po (thank you, August.)
66 * Small cleanups in Molecule interface
68 * Spacing related elements perform suicide after calculating
69 distances. This saves a some memory, approximately 2 to 5 % ?
71 * Small cleanups in line breaking: Paper_column stores springs and
72 rods in only one place now. All fields relating to energy have been
75 * Don't generate all output Scheme in memory, but evaluate to output
76 file immediately. This will reduce memory usage a little.
78 * Use STL's map for Dictionary template
80 * Substitute pointers on element properties of the root Line_of_score
83 * Added toplevel doc target, to support building doc with --srcdir
85 * Removed cygwin build stuff; updated versions at:
87 http://appel.dyndns.org/lilypond/gnu-windows/cross
89 * Fixed lily.scm to handle incipits (thanks, Mats)
95 * Made bugfix in smob handling: delete the C-part of freed smobs and
96 be honest about amount of allocation and deletion, so that GUILE
97 doesn't overestimate the amount of memory available.
99 * Faq update: nicer blank note paper, courtesy Mats Bengtsson.
101 * Bugfix: don't crash on durations that are not a power of 2.
103 * Build manpages during `make all'
105 * Bugfix: don't do absolute comparisons in Polynomial::clean ().
107 * Bugfix: set visibility-lambda for key signature created by
108 createKeyOnClefChange. Fixes disappearing key signatures.
110 * Bugfix: make System_start_delimiter of bar-line type invisible when
111 it spans only one staff.
116 * Item cleanups. Copying items and rearranging pointers are done in
117 separate passes, which makes the code cleaner. This fixes a problem
118 with some items not disappearing from hara-kiri staffs.
120 * Use Scheme for Key_item data members.
122 * Don't use regex in chord-names.scm under windows; hybrid chordnames
123 user+calculated will be partly broken.
128 * Junked Shift_tuple from collision; Now it uses SCM.
130 * Bugfix of documentation and test-file of tuplet.
132 * Bugfix type string of repeated music is copied. This fixes declared
135 * Junked various cruft from lily.scm
137 * Use interfaces symbols instead of C++ class-name for assigning generic
140 * Junked Dictionary from Piano_pedal_engraver and
141 Piano_pedal_performer.
143 * Introduced boolean element property no-spacing-rods: ignore this
144 item for hard constraints.
146 * Bugfix: added sanitised TeX fragment in faq.texi
148 * Bugfix: merge equal Bar_reqs
153 * Small fixes for \cresc and \endcresc
155 * Release properties of unbroken spanners & items after doing
156 handle_broken_smobs (); should conserve a little memory.
158 * Fixed handling of orphaned score-elements. Any element that does
159 not have its Line_of_score as a ancestor in both directions, is silently
160 removed from the output. This guarantees that programming errors
161 don't result in coredumps from Dimension_cache::common_refpoint ():
162 element->line_l () is always a common reference point.
164 * Bugfix: set visibility-lambda of clef and octavation-8 explicitly
165 for default case. Now the octavation 8 is not printed at every
171 * Changed noteHeadStyle properties to symbols, for example
172 \property Voice.noteHeadStyle = #'cross
177 * Rewrite of chord-name production in scheme. There are two major styles
178 now, banter and american. To get american style, use
180 \property ChordNames.chordNameStyle = "american"
182 Most anything should be possible now. See input/test/american-chords.ly
184 * Added isinf check to configure.in, and isinf macro from guile to
185 bezier.cc; solaris has no isinf ().
187 * Fixed star-spangled-banner with not-so-nice \bar "|." fix. Almost
190 * Added output property to regression test.
192 * Fixed warning of creating existing outdir.
194 * Added `Mark' interface to text-items that are marks (thanks, HW).
201 * Corrected glossary.tely
203 * Corrected \mark font handling. feta-nummer font only of the
204 string is all numeric.
206 * Implemented noteHeadStyle lookup in Guile. Reintroduced the style
207 "harmonic" and added "baroque" (normal note shapes except for
208 brevis and longa which are square).
210 * Simplified ly2dvi using the power of the geometry package.
212 * Improved heuristic size calculation of TeX macros. Handles e.g.
213 "\\u{a}", "\\"{o}" and "\\^{u}" correctly.
218 * Bugfix: don't hang on zero-duration.
220 * Various glossary updates (thanks, Christian)
228 * Drastically reduced vertical space used by headers/footers, when using
229 ly2dvi. See input/test/fill-a4.ly.
231 * Fixed bug with colons appearing on repeat span-bars.
233 * Added Bar_number_engraver to standard Score context
235 * Construct octavation scripts in the clef-engraver; this fixes the
236 hara-kiri + clef8 problem
244 * Fixed chord-name customisation and made small chord-name build fixes.
246 * Accidentals with chord-names smaller and as superscript.
248 * Do some extra footify (works only once) while making html docs.
253 * Debian patch (Thanks Anthony)
255 * Rewrote Bar_number_engraver and Mark_engraver and removed
256 Bar_script_engraver as baseclass. Both Bar_number_engraver and
257 Mark_engraver are simpler and more robust.
259 * Fixed precedence of \property verticalDirection and dynamicDirection
261 * Fixed keys without barlines
263 * Fixed StaffGroups: removing `\consistsend "Axis_group_engraver"'
264 puts alignment in function again
266 * Fixed StaffGroup + GrandStaff combination.
268 * Music is now mandatory as the first thing in a \score{} block
275 * Implemented una-chorda and sostenuto piano pedals in performer and engraver.
277 * Added Properties textScriptWordSpace and chordNameWordSpace.
279 * Junked old lyrics in star-spangled-banner.
281 * Added a Piano_pedal_engraver.
283 * Removed some empty files.
285 * Created piano pedal symbols: * - . P e d.
287 * Fixed ps-to-pfa.py to handle multiple unfills.
289 * Moved accordion symbols out of feta-script to end of font.
291 * Bugfix: don't create tfm's, pfa's etc of feta-test fonts.
293 * Fixed blot_diameter for small resolutions.
298 * Put global element list into Line_of_score, instead of
299 Paper_score. post processing (the stage after line breaking) is now
300 truly done per-system, and we got rid of an ugly hack to get font
303 * Bugfix: set the group-interface of System_start_delimiter.
305 * Cleanups of Break_algorithm and derived classes, Move
306 broken_col_range () to Line_of_score, remove Paper_score::col_l_arr_
308 * Bugfix for accordion symbols.
310 * Various patches to prevent crashing when do_brew_molecule gets
311 called before after_line_breaking (). This was a problem in Spanner
320 * Made a quick try at piano pedal performer, damper pedal only.
322 * mf/feta-accordion.mf: Fixed strange turning paths.
324 * mf/feta-beugel.mf: Fixed infinity errors.
326 * Use a more discriptive name for windows setup.zip.
328 * mf/GNUmakefile: Have logs as last target, so that normally, they're
331 * stepmake/stepmake/metafont-rules.make: Don't remove the .log files.
332 The logs are a target, removing them retriggers make.
334 * stepmake/stepmake/metapost-rules.make: Remove the correct log and tfm
335 files, ie the ones that clutter the source directory, not the target logs.
337 * Windows distribution: faked symlink for cmtfm. Setup.zip should now be
338 standalone; ie, no need for Cygnus' usertools anymore.
343 * Documentation/ntweb: Updated angels.ly to match current syntax.
344 Also updated index.texi.
349 * Change all occurances of Staff_margin_engraver to
350 Instrument_name_engraver, add a convert-mudela rule
352 * Change status == busy assert into programming error
360 * Lots of fixes to windows distribution scripts.
362 * Added configuration features --program-prefix, --program suffix.
364 * lily/my-lily-parser.cc (get_chord): Bugfix, don't use deleted pitch.
365 This fixes inversions c/g and bass additions d/+c on chords.
370 * Avoid that xxxXXXVerticalExtent is used for empty HaraKiriStaff
376 * Debian patches (thanks Anthony!)
378 * Use symbols for prefatory matter spacing. Do not use the typename
379 for looking up item pairs in the table, but read element property
382 * Instrument_name_engraver, uses break alignment instead of
385 * System_start_delimiter_engraver, System_start_delimiter, uses a
386 spanner for the braces/brackets at the left of the system. Remove all
387 old Span_score_bar engravers.
389 * Removed Base_span_bar_engraver::use_prority_b_, and moved
390 Base_span_bar_engraver into Span_bar_engraver.
395 * mutopia/Coriolan/violino-2.ly: Bugfix: wrong pitch.
397 * input/test: Removed stale AutoStaffSwitch examples.
399 * mutopia/E.Satie: Fixed gnossiene-4, doing \autochange. Removed
400 stale copy of gnossiene-4.
402 * buildscripts/make-cygwin-cross.sh: Made some small .zip package fixes.
404 * make/lilypond.spec.in: Made some bugfixes for _prefix, preparations
405 for cross-building to Cygwin.
407 * buildscripts/make-cygwin-cross.sh: Now using rpm packages.
412 * added \property XXXMinimumVerticalExtent, \property XXXExtraVerticalExtent
414 * New_chord_tremolo_engraver: make tremolo beams from
416 \repeat "tremolo" NUMBER <Music-expression>
418 Removed support for "old-style" tremolos.
420 * Add a convert-mudela function for the conversion "\key A;" to "\key a;
422 * Read \property measurePosition within the engraver code, instead of
423 looking up the Timing_translator.
425 * star-spangled-banner.ly: add Bar_engraver to LyricsVoice
427 * Changed all .fly and .sly files to .ly files. Propose to dump .fly
436 * buildscripts/mf-to-table.py: feta dep files are now opened with write
437 binary option. This avoids carriage return linefeed problems and
438 windows while not affecting unix.
440 * Documentation/hacking.texi: Fixed a texinfo syntax error
442 * stepmake/bin/package-zip32.sh: Fixed or Removed some legacy, 1.2.x,
445 * Documentation/ntweb/index.texi: Fixed broken links, added 1.3.39 links.
450 * Glossary updates by Christian Mondrup.
452 * Bugfix: use generic properties in lyrics too. This fixes the
453 \property textStyle for lyrics.
455 * Score_element::preset_extent(), used by \property
456 XXXVerticalExtent, so hard code the size of a vertical group.
458 * Don't fix up reference points for originals of broken
459 spanners. Fixes spurious "orphaned score-element" warnings.
461 * buildscripts/make-cygwin-cross.sh: Use rx-1.5 instead of regex (Jeffrey).
463 * scm/lily.scm: Fixed check for Windows: by default don't use scm regex.
465 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: Significantly smaller
468 * buildscripts/make-cygwin-cross.sh: Compile native package GNU regex,
469 which should fix Windows problems with guile. Also added input directory
472 * stepmake/aclocal.m4: Added decent checking for version of guile, and
473 fixed warning message.
475 * lily/lexer.ll (My_lily_lexer): Bugfix: lookup chordmodifiers in the
476 chord-modifier table (not in the pitch list).
484 * General cleanups of My_lily_parser.
486 * Start of a Chord_tremolo_iterator for the `\repeat 4 "tremolo"'
489 * Moved Score_element::do_space_processing out of the dependency
492 * Use Scheme for notename tables. Removed uppercase letters for low
493 octave notes. Removed Notename_table.
495 * Fixed core dump with declared "\key ; "
497 * Extra robustness warning for Side_position_interface::aligned_on_self ()
499 * Extra robustness: make sure that first and last columns are breakable.
504 * stepmake/aclocal.m4: Added support for cross-compiling with guile.
506 * buildscripts/make-cygwin-cross.sh: A try at dropping cygwin1.dll
507 dependency by using mingw. Compiling guile is too much to ask
508 for mingw, though. Also:
509 - rename python scripts .py (request from Alain)
510 - install native packages under their own, separate root. (Alain)
512 * lily.scm: Don't use regex module when running on
515 * lily/staff-margin-engraver.cc (acknowledge_element): If
516 possible, hang y-axis of margin script to span-bar. This fixes
517 vertical placement of margin scripts attached to staff groups.
519 * help2man-rules.make: Fixes for generating manpages by copying
520 and for building using --scrdir.
522 * stepmake/stepmake/generic-targets.make: Preserve date stamp of
523 config.h, version.hh files file when copying.
525 * buildscripts/make-cygwin-cross.sh: made number of fixes:
526 - add `Cygnus/' prefix to directories in .zip-file too.
528 - don't link to cygwin1.dll
530 * stepmake/stepmake/install-targets.make: bugfix, don't fail if directory
531 is not emty when uninstalling.
533 * stepmake/stepmake/generic-targets.make: added man target.
535 * buildscripts/make-cygwin-cross.sh: new script for cross-building cygwin
536 development tools and lilypond executable.
538 * Documentation/ntweb/lilypond-manpages.patch: provide pre-built
539 manpages, so that make doesn't fail on help2man trying to execute
540 a GNU/windows executable.
542 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: new patch for
545 * flower/libc-extension.cc (memmem): cygwin compile fix.
553 * (generic-property.scm) added \property tieDash to set dashing on
556 * Removed ly_eval_str(), we should use scm_eval (Scm_object).
558 * Removed scm_to_array (), array_to_scm (), associated junk. Reverted
559 undocumented .29 patch that made Bezier::control_ into an
560 Array<Offset>. Added some comments documenting the reasons for the
563 * Revert generic-property.scm of .37 fix, fix the real problem in
564 property-engraver.cc: use the right symbol to check if element
565 property is already set.
570 * Fixed srcdir build, so that you can do:
572 tar xzf releases/lilypond-x.y.z
575 ../lilypond-x.y.z/configure
578 as with any other gnu package. All build output goes to <build>/out.
580 * Changed and fixed use of different configurations, and different output
581 directories. Finally, you can use different configurations alongside
582 eachother. From make/stepmake.make:
584 # Use alternate configurations alongside eachother:
586 # ./configure --enable-configsuffix=debug
589 # uses config-debug.make and config-debug.h; output goes to out-debug.
592 # Use same configuration, but different output directory:
596 # uses config.make and config.h; output goes to out-www.
600 * Fixed performance of (de)crescendi.
602 * Better documentation for arithmetic_multiplier and arithmetic_basicspace
605 * Added instrument-equaliser for MIDI output, see scm/midi.scm, and
606 properties midiMinimumVolume, midiMaximumVolume, ranges [0,1].
608 * Changed absolute midi volume settings into factor of full scale.
610 * Fixed another dynamic-line-spanner bug, it gets hairy.
612 * Added warning for spanners that are not fully contained in parent spanner.
620 * Abstract Align_element into Align_interface. Removed
621 Axis_align_{item,spanner}, Align_element, Super_element, all multiple
622 inheritance in the backend.
624 * new Gade score, INSTALL.texi fixes (thanks, Mats)
626 * Removed Item::hpos_f (), Score_element::{get,set}_real ()
628 * comments detailing properties for Axis_group_interface,
629 Side_position_interface, Score_element, Item and Spanner
634 * Fixed vertical dimensions of elements in dynamic line spanner by adding
635 axis-group to dynamic line spanner.
637 * Bugfix: line-spanner lasts always full duration of (de)crescendi.
639 * Bugfix: broken (de)crescendi on a dynamic-line-spanner.
641 * Bugfix: compilation dynamic-engraver.
643 * Added and updated a faq about postscript and ghostscript.
645 * Fixed order of slurVerticalDirection verticalDirection in
646 generic-property.scm. Similar fixes for Stem, Tie, etc.
648 * Added a Text_engraver to GraceContext. Maybe it was removed on
649 purpose: scripst on grace notes seem broken, they appear on the
652 * Bugfix: volume effect of (de)crescendi was sometimes wrong way round.
659 * textEmptyDimension changed into textNonEmpty, default: off,
660 ie. texts don't occupy space.
662 * Use STL map for Lookup::lookup_p_tab_p_
664 * Abstracted Axis_group_element into Axis_group_interface, and removed
665 Axis_group_element. This eliminates some multiple inheritance in the
671 * Added minimum-space property to Side_position_interface. Used in
672 positioning of Volta_spanner: voltaMinimumSpace.
674 * Fixed and cleaned-up volta-spanner.
676 * Moved directional-element.cc -> directional-element-interface.cc
678 * Renamed all `process_requests' to `process_music', which fixes
681 * Fixed dimensions (more x-y interchanges) of brace, bracket and
684 * Bit half-baken fix in to get similar vertical placement of orphaned vs.
685 line-spanned dynamic elements.
687 * Added property bracketCollapseHeight: the minimal size of a staff bracket
688 that will be typeset. Smaller brackets will not be displayed. This
689 fixes the (in 1.3.x reintroduced) funny duck-beak-bracket-bug (sorry).
691 * Removed some dissonant chords from Coriolan
696 * Removed Documentation/programmer directory
701 * Small enhancements to Staff_margin_engraver:
702 - by default, the marginScript left aligns the text
703 - to set the text style, use property marginScriptTextStyle
704 - to change the alignment, use property marginScriptHorizontalAlignment
705 (centred and right alignment require manual padding settings).
707 * Print a friendly message if the manual pages failed to build.
709 * Bugfix: dynamicDirection now overrides verticalDirection setting.
711 * Warning messages and nl.po
713 * Fixed vertical alignment for all dynamic items and (reluctantly)
714 reinstated old directional behaviour for orphaned dynamics.
716 * Finished maximumRestCount property.
723 * Print key without setting key, syntax "\key ;". General cleanups of
726 * Add paragraph tags in HTML output of mudela-book. Music fragment
727 don't run into the text anymore.
729 * Bugfix: don't align the first line of text. (Lookup::text ()).
731 * Abstract away data members of Axis_group_element, Align_element
737 * Added helpful properties instrumentScriptPadding/instrScriptPadding for
738 Staff_margin_engraver.
740 * Removed some empty files, substituted (c) 1999 occurrences.
742 * Added \property maximumRestCount. It will prevent showing (or actually:
743 moving in case of a collision) more than maximumRestCount similar rests.
746 * Rewrote Staff_margin_engraver. Staff margin texts now hang on a new
747 breakable item: Left_edge_item.
749 * Fixed vertical alignment for dynamic elements. Orphaned dynamic items
750 (not supported by a Dynamic_line_spanner) still collide with Staff,
751 although they now have staff support, which was supposed to fix this.
753 * Fixed Staff_margin_engraver for "instrument", "instr" is still broken.
755 * Dynamic elements are only put in a Dynamic_line_spanner if there
756 actually is more than one adjacent note-column with a dynamic.
757 This breaks the fine looks of all dynamics, again :-)
768 * Experiment: use STL map for Scheme_hash_table; Is there a speedup?
770 * Bugfix: print brace iso. bracket for Piano / GrandStaff
772 * Change naming: change do_post_processsing into after_line_breaking,
773 do_pre_processsing into before_line_breaking and do_process_requests
774 into do_process_music.
776 * Bugfix in hash-table.hh: do quadratic probing, and not cubic probing.
778 * Display property name for type error.
780 * Cleanups for Dynamic_engraver and Dynamic_line_spanner.
782 * Warn if last column in score is musical. Helps catch programming errors.
784 * Spanner::spanned_drul_ now is private.
786 * Rewrote some bar code: moved molecule functions out of Lookup.
791 * Embedded newlines in text items are now allowed. This helps avoiding
792 TeX-hacking in some cases. See input/test/coriolan-margin.ly
794 * Fixed stupid x-y interchange bug for staff-bracket. This fixes
795 placement of staff-brackets.
797 * Fixed bracket/arch-thickness interchange bug, and made bracket a bit
800 * Fixed slur/bezier-beautiful name mismatch. This should fix the steep
801 slurs that were apparently reintroduced in 1.3.29.
803 * Made some small fixes to Coriolan.
805 * Removed duplicate lily/output-property-engraver.hh.
807 * Removed optional use of vanilla spanner in Dynamic_engraver.
809 * Fixed (measured) tremolo for Stem and Beam. Merged declarations
810 stem-engraver.hh and chord-tremolo-engraver.hh into their .cc
811 implementation file. Also fixed looks of Chord tremolo, input and
812 implementation is still ugly.
814 * Added *.yy and *.ll to TAGS, to that tags-find-replace doesn't omit
820 * Fixed \specialkey and \normalkey. Updated documentation.
827 * Fixed and cleaned-up Dynamic_engraver. Optionionally uses vanilla
828 spanner instead of Dynamic_line_spanner.
830 * Made gcc-2.95 compile fix in libc-extension.
832 * Various fixes to Coriolan, score starts to look acceptable.
834 * Moved optional text of crescendo into Crescendo spanner. Fixed horizontal
835 and vertical alignment of dynamics.
837 * Added new text crescendo spanners to Coriolan and made some fixes.
838 If you're using timidity, use the -EO option to prevent notes get
839 stuck. I'm not sure whose fault this is, Lily's MIDI output may be
840 stretching the standard a bit.
842 * Adjacent dynamic markings are now grouped on a horizontal line, but it's
843 not perfect yet: they're always below the staff and no horizontal spacing
844 is done. Also, character metrics of dynamics are still not used.
845 See: input/test/crescendi.ly and input/test/dyn-line.ly
847 * Cleaned up Span_dynamic_performer.
854 * Fixed the page layout, reintroducing space for the header and
855 trying to keep piece titles on the same page as the piece.
856 The header and footer can now contain several lines.
861 * Lily now also performs crescendi and decrescendi in MIDI output:
862 Span_dynamic_performer (bit scrappy).
864 * Added preliminary support for crescendi/decrescendi other than `hairpins',
865 eg: `cresc. poco `a poco -- -- --'
867 * Made MIDI tie performance fix.
872 * Lily now performs absolute dynamics in MIDI output.
874 * Included David's comments on opus47 in TODO.
879 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
880 fixes and remainder french horn-1,2; trombone-1,2;
881 fagotto-1,2; timpani; and several fixes.
886 * Remove some old doco from programmer/ and put on personal homepage.
888 * Removed union-find from flower library.
890 * Only quantise tie horizontal part inside the staff.
897 * Report type errors for \property. Helps with converting 1.2 input
899 * Use Scheme for Align_element; fixed graceAlignPosition
900 and removed \property alignmentReference in the process.
902 * Use generic properties for lyrics too. This fixes \property
906 * Add relative distance for constraints between non-column items.
908 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
909 increased automatically.
911 * Translators now only change properties of their own context. This
912 removes the 2nd argument to Translator::get_property()
914 * Bugfix for Metapost mode
919 * Updates of glossary (Christian Mondrup)
921 * Bugfix with bar number placement
923 * Moved links to bibliography/ and misc/ to main index.
928 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
929 Slurs are now calculated just once.
931 * Bezier_bow gets constants from paper. Still no sensible solution for
932 magic asymmetry gradient step constants.
934 * Reinstantiated tangent-controls, more flexible than ever. You can choose
935 between area asymmetry and tangent-controls. My guess is, tangent controls
936 will be junked in 1.3.30.
938 * Slur area: only look at x-gradient.
940 * Added credits for some symbols of as5/9 fonts.
942 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
944 * Bugfix: midi2ly put out recent version (ugh).
949 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
952 * Removed Gade score. To appear (shortly?) on Mutopia.
954 * Make Bar_script_engraver look for typeVisibilityFunction (eg
955 property barNumberVisibilityFunction). Changed the names of the Scheme
956 functions to be understandable. See input/test/bar-script-visibility.ly
958 * rewrite of class Molecule. It has now reached the ultimate quality
959 plateau. All molecule data is now shared.
964 * Update of the glossary by Christian Mondrup
966 * Moved horn-concerto-3 out of tarball to private website, removed
967 W.A.Mozart subdirectory.
972 * Bugfix: don't make giant ties if the horizontal part of tie is near
975 * Small optimizations to be a little more careful with mem usage.
977 * Website change: put all examples in one directory.
979 * Removed Atom as a separate type. Now use SCM, and since we use
980 function composition, Atoms are immutable, so they don't have to be
981 copied. This makes life easier, hopefully this is quicker and uses
987 * Bezier_bow: minimise_enclosed_area
995 * Tuplet-spanner slope calculation now looks better on tupletted rests
996 (patch courtesy Laurent Martelli)
998 * Bugfix (Staff_performer::new_instrument_str ()) check type of
999 \property "instrument"
1001 * New mechanism for breaking lines: do not copy & prune the element
1002 property list separately, but combine these steps. Dramatically
1003 reduces memory usage for large scores.
1010 * Bugfix: font used in volta-spanner calculation.
1012 * Added simple selection list to webpage, inspired by sawmill.
1014 * Devised kludge for ascii 5 character font pitches.
1016 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
1021 * Plug memory leaks related to Moment:
1022 - Spacing_engraver::do_pre_move_processing ()
1023 - make_rational ()/make-rational
1024 - Paper_column::Paper_column ()
1026 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
1028 * Plug memory leak in Score_engraver::set_columns ()
1030 * Plug memory leak in Scheme_hash_table::set()
1032 * Plug memory leak in Score_element::molecule_extent ()
1034 * Bugfix: don't crash if a slur doesn't span anything.
1036 * Bugfix: don't crash if doing beams without a staff symbol.
1038 * Generic element property setting:
1040 \outputproperty #predicate #'symbol = #value
1042 Will set the element property symbol to value, for any elements that
1043 return true for PREDICATE. This allows you to virtually tweak *ANY*
1044 property of the output. Example in input/test/generic-output-property.ly
1049 * lilypond as as2ly: --help and --version to stdout. Regular identify
1050 to stderr. This fixes help2man's manpage generation.
1052 * configure: substitute full path for perl and guile in scripts.
1054 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
1056 * Bugfix: default font now user settable
1058 * as2text: handle plain ascii font, read from stdin, you can now do:
1060 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
1065 * Bugfix: second half of broken ties now are displayed again.
1067 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
1068 it horizontally on the clef.
1070 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
1072 * Bugfix: unbroken repeat barlines now work, eg. |:
1074 * Added Request_iterator to make more flexible constructions possible.
1078 * as2text: catch missing font/character errors, added default font, set text.
1080 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
1082 * Ascii output, minimal support:
1083 - AsciiScript Fonts: mf/*.af
1084 - Init files: ly/*-as.*ly
1085 - AsciiScript translation to text: scripts/as2text.scm
1086 - input/test/as.fly input/test/as1.fly
1087 - Output support: lily/lily.scm
1089 lilypond -f as -i init-as.fly input/test/as.fly
1095 * The horizontal part of ties will avoid collision with staff lines.
1097 * Plugged memory leak: don't protect Atom function.
1099 * Lookup cleanups. Made lots of functions static. Moved some code out
1107 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
1108 does not delete any of the file_ly*.tex.
1110 * Added header and footer support in ly2dvi.py
1115 * Added a ROADMAP file explaining the source directory layout.
1117 * Minor tweak in the feta 6 and 9 numeral

1123 * Updated the webpage to be a little more chatty.
1125 * Small Local_key_engraver optimization: only lookup timing engraver once.
1127 * Fixed dashed slurs
1129 * Rewrite of Slur code. Be much more picky about slur shapes. We try
1130 to offset the slur instead of bending it too much
1132 * Look at stem directions for tie direction.
1134 * Compound multimeasure rests. Put measures_i_ variable in an element
1135 property. Made the symbol a lot wider.
1137 * Time signature small cleanups.
1142 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
1145 * Breathing marks now have a direction by default.
1147 * Do set generic script properties.
1149 * Also put tuplet brackets under notes.
1151 * Score_element_info: only store origin of element, but not the path
1152 to parent translators. Saves a little memory, and removes some complexity.
1158 * Autobeaming in time sigs that don't have 1/4 beats fixed.
1160 * (De)crescendi should now work. (Thanks Michael)
1162 * Better error reporting for conflicting time signatures.
1164 * Line_number_engraver: output locations of note head
1165 definitions. Very handy when entering complicated scores.
1167 * Rewrote multi measure rest support: now they are entered as spanners
1168 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
1170 { \commandspanrequest \start "rest"
1172 \commandspanrequest \stop "rest"
1175 * Removed support of percent style repetitions.
1177 * Put texts outside the staff.

1183 * ly2dvi: Remove unnecessary space for the page headers.
1185 * Bugfix convert-mudela
1190 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
1193 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
1194 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
1195 \property tupletInvisible will stop all tuplet spanner creation.
1197 * Don't go berserk if tuplet spanner is on only one column.
1199 * Use SCMs & Smobs for Molecules & atoms. This uses less
1200 scm_(un)protect_object () calls, so the output stage should be faster.
1202 * Added \property tupletSpannerDuration, to make multiple tuplet signs
1205 * Some programming Errors in spacing are now caught. Lily does not
1206 hang when encountering degenerate springs.
1208 * Allow beams to start and end over rests
1212 * Fix disappearing clefs when clefs are not printed with a barline.
1217 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
1218 input/test/beam-control.fly
1219 * Added \context Voice to .fly and .sly; the default \context Staff is almost
1220 never what you expect
1221 * Fixed decision for .sly/.fly in lilypond-mode.
1226 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
1227 Cleanup mf-to-table.py
1229 * Fixed embarassing slur bug.
1234 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
1239 * lilypond-mode.el for emacs supersedes mudela-mode.el
1241 * Tuplet spanners don't collide with encompassing notes.
1243 * Gobbled Adobe parseAFM* code, for future use.
1245 * Big 1999 to 2000 search/replace.
1247 * Big interline to staff_space search/replace for mf files.
1249 * Removed Bow class, and split code into Tie and Slur
1251 * Don't put scripts on grace notes.
1253 * Font_metric uses SCM for name field.
1255 * Various compilation fixes.
1260 * Bugfix: beams with less than one (visible) stem
1262 * small fixes to pa.ly
1267 * Fixed bug that made multi-measure rest barnumber counts go wild.
1268 (even more scm2int/int2scm mixups!)
1270 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
1272 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
1277 * Remove Paper_def calls in bezier-bow.cc
1279 * Remove data members of Tuplet_spanner, Volta_spanner
1281 * hang_on_clef, property hangOnClef removed
1283 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
1284 function to determine breaking behavior.
1286 * More Scheme typechecking.
1288 * Be strict about the difference between strings and symbols for conversion.
1290 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
1293 * Partial French translation, courtesy Laurent Martelli.
1295 * Small corrections in NL translation.
1300 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
1301 we have a longa note head. noteHeadStyle = "harmonic" is not
1302 supported anymore. (for now, that is)
1304 * Reference manual update. Document \properties with examples
1306 * fix mudela-book --help
1308 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
1309 Key_item::c0_position_
1311 * Clef_engraver general cleanup. Use alists (\property
1312 supportedClefTypes, clefPitches) for clef types.
1314 * Use progress_indication () for progress. Don't include <iostream.h> directly
1315 Don't include <string.h>, <math.h> from headers.
1321 * \property stemCentered (boolean): centers stem on note head. See
1322 input/test/stem-centered.ly
1324 * input/trip.ly, small test of lots of features.
1326 * \property Staff.collisionMergeDotted: merge equal noteheads
1327 with different dot count. See input/test/collision-merge-dotted.fly
1329 * Dotted rest bugfix
1331 * Don't crash if a slur does not span any notes.
1333 * Volta repeats fixed.
