13 ++ b/CHANGES Sat Jun 17 16:10:49 2000
25 * First attempt to reintroduce support for keys with different
26 accidentals in different octaves.
31 * Removed String_identifier, and use the type system of GUILE instead.
33 * Fixed \key PITCH MODALITY syntax. The modality argument is now
34 mandatory, a rule in convert-mudela has been added.
36 * Cleaned up buildscripts/ directory: removed obsolete scripts.
38 * Use Scheme_hash_table for identifier Scopes. Scheme_hash_table is
39 based on STL and should be faster than hash_table.
45 * Fixed scm_un/protect_object for guile-1.3.4 and 1.3.5 snapshots,
46 in the process reduced number of protect/unprotect calls. With
47 guile-1.3.5 snapshot, memory usage has decreased by 1/5th, now
48 just 10% above the 1.2 level. Also, Lily's a bit faster.
50 * Fixed make diff bug in stepmake to be able to make this diff :-)
55 * Rewrote key sig support. Now key signature can also be controlled
56 by setting keySignature and localKeySignature properties, eg.
58 \property keySignature = #'((2 . -1) ( 4 . -1) (6 . -1))
60 sets a key signature of `es ges bes' (an unusual key signature).
62 Keys are internally represented as transpositions of the c-major
63 scale. Printing the key signature for a scale is done by filtering out
64 all non-natural accidentals.
66 * Removed support for \keysignature, and \key something \minor; Newkey
72 * Fixed pedal items (hw)
74 * Changed configure option tex-tmfdir to tmf-path now accepting multiple
75 tfm directories. Automated links to cmr and amstex tfm font directories.
77 * Replaced one scm_assoc () u-turn slipped through jcn1
79 * various GUILE 1.3.5 compile fixes
81 * Added `Ped' as a compound symbol font and removed silly scheme kerning.
83 * Replaced some scheme assoc u-turns with scm_assoc ()
85 * Ran po-update (mostly because of new ja contribution).
90 * Cleaned-up scheme list to text conversion for Chord_name and
91 fixed horizontal kerning.
93 * Added examples for american (slashed o) and jazz (black triangle),
94 see input/test/{american-chords.ly,jazz-chords.ly}
96 * Made guile-1.3.5 compile fixes
101 * Fixed typo in Dots::do_brew_molecule (); this fixes the disappearing
104 * Rewrote key signature administration; now Scheme is used; Octave and
105 Key have been junked in favor of Newkey.
107 * japanese .po file included (thanks, Japanese team!)
112 * Fixed several forgotten molecule-callbacks
114 * Fixed first clef in score; now F clefs are also possible.
119 * Updated FAQ with two useful GDB macros.
121 * Several fixes in the documentation.
126 * Made (dutch) po-update
131 * Molecules are now generated via callbacks exclusively; most calls to
132 set_elt_property ("transparent", SCM_BOOL_T) have been replaced by suicide().
137 * Experimental property collapse for most score-elements. (notable
138 exceptions: Scripts, pedals). Change all Score_element constructors to
139 take a basic-property list. The suffix of a property list may be
140 shared by several score-elements, for instance all default G-clefs in
141 a score share the following settings
144 (break-align-symbol . Clef_item)
145 (visibility-lambda . ,begin-of-line-visible)
147 This should reduce memory usage further.
149 * Magically fixed the disappearing Lyrics problem.
151 * Removed used_b_ field from Score_element.
153 * Massive search-replace patch: store pointers and properties
154 separately, in preparation of property collapse.
160 * Bugfix: don't crash on tuplet spanners that don't contain any notes.
162 * Cleanup of Dimension_cache: removed a few redundant
163 fields. Slightly lower memory usage (32 bytes per
164 score-element). Dimension_cache is now a `dumb' struct again.
166 * Add array index to priority field of text scripts to ensure that
167 order is unique, and sensible.
169 * Added an element count statistic.
174 * russian.po (thank you, August.)
176 * Small cleanups in Molecule interface
178 * Spacing related elements perform suicide after calculating
179 distances. This saves a some memory, approximately 2 to 5 % ?
181 * Small cleanups in line breaking: Paper_column stores springs and
182 rods in only one place now. All fields relating to energy have been
185 * Don't generate all output Scheme in memory, but evaluate to output
186 file immediately. This will reduce memory usage a little.
188 * Use STL's map for Dictionary template
190 * Substitute pointers on element properties of the root Line_of_score
193 * Added toplevel doc target, to support building doc with --srcdir
195 * Removed cygwin build stuff; updated versions at:
197 http://appel.dyndns.org/lilypond/gnu-windows/cross
199 * Fixed lily.scm to handle incipits (thanks, Mats)
205 * Made bugfix in smob handling: delete the C-part of freed smobs and
206 be honest about amount of allocation and deletion, so that GUILE
207 doesn't overestimate the amount of memory available.
209 * Faq update: nicer blank note paper, courtesy Mats Bengtsson.
211 * Bugfix: don't crash on durations that are not a power of 2.
213 * Build manpages during `make all'
215 * Bugfix: don't do absolute comparisons in Polynomial::clean ().
217 * Bugfix: set visibility-lambda for key signature created by
218 createKeyOnClefChange. Fixes disappearing key signatures.
220 * Bugfix: make System_start_delimiter of bar-line type invisible when
221 it spans only one staff.
226 * Item cleanups. Copying items and rearranging pointers are done in
227 separate passes, which makes the code cleaner. This fixes a problem
228 with some items not disappearing from hara-kiri staffs.
230 * Use Scheme for Key_item data members.
232 * Don't use regex in chord-names.scm under windows; hybrid chordnames
233 user+calculated will be partly broken.
238 * Junked Shift_tuple from collision; Now it uses SCM.
240 * Bugfix of documentation and test-file of tuplet.
242 * Bugfix type string of repeated music is copied. This fixes declared
245 * Junked various cruft from lily.scm
247 * Use interfaces symbols instead of C++ class-name for assigning generic
250 * Junked Dictionary from Piano_pedal_engraver and
251 Piano_pedal_performer.
253 * Introduced boolean element property no-spacing-rods: ignore this
254 item for hard constraints.
256 * Bugfix: added sanitised TeX fragment in faq.texi
258 * Bugfix: merge equal Bar_reqs
263 * Small fixes for \cresc and \endcresc
265 * Release properties of unbroken spanners & items after doing
266 handle_broken_smobs (); should conserve a little memory.
268 * Fixed handling of orphaned score-elements. Any element that does
269 not have its Line_of_score as a ancestor in both directions, is silently
270 removed from the output. This guarantees that programming errors
271 don't result in coredumps from Dimension_cache::common_refpoint ():
272 element->line_l () is always a common reference point.
274 * Bugfix: set visibility-lambda of clef and octavation-8 explicitly
275 for default case. Now the octavation 8 is not printed at every
281 * Changed noteHeadStyle properties to symbols, for example
282 \property Voice.noteHeadStyle = #'cross
287 * Rewrite of chord-name production in scheme. There are two major styles
288 now, banter and american. To get american style, use
290 \property ChordNames.chordNameStyle = "american"
292 Most anything should be possible now. See input/test/american-chords.ly
294 * Added isinf check to configure.in, and isinf macro from guile to
295 bezier.cc; solaris has no isinf ().
297 * Fixed star-spangled-banner with not-so-nice \bar "|." fix. Almost
300 * Added output property to regression test.
302 * Fixed warning of creating existing outdir.
304 * Added `Mark' interface to text-items that are marks (thanks, HW).
311 * Corrected glossary.tely
313 * Corrected \mark font handling. feta-nummer font only of the
314 string is all numeric.
316 * Implemented noteHeadStyle lookup in Guile. Reintroduced the style
317 "harmonic" and added "baroque" (normal note shapes except for
318 brevis and longa which are square).
320 * Simplified ly2dvi using the power of the geometry package.
322 * Improved heuristic size calculation of TeX macros. Handles e.g.
323 "\\u{a}", "\\"{o}" and "\\^{u}" correctly.
328 * Bugfix: don't hang on zero-duration.
330 * Various glossary updates (thanks, Christian)
338 * Drastically reduced vertical space used by headers/footers, when using
339 ly2dvi. See input/test/fill-a4.ly.
341 * Fixed bug with colons appearing on repeat span-bars.
343 * Added Bar_number_engraver to standard Score context
345 * Construct octavation scripts in the clef-engraver; this fixes the
346 hara-kiri + clef8 problem
354 * Fixed chord-name customisation and made small chord-name build fixes.
356 * Accidentals with chord-names smaller and as superscript.
358 * Do some extra footify (works only once) while making html docs.
363 * Debian patch (Thanks Anthony)
365 * Rewrote Bar_number_engraver and Mark_engraver and removed
366 Bar_script_engraver as baseclass. Both Bar_number_engraver and
367 Mark_engraver are simpler and more robust.
369 * Fixed precedence of \property verticalDirection and dynamicDirection
371 * Fixed keys without barlines
373 * Fixed StaffGroups: removing `\consistsend "Axis_group_engraver"'
374 puts alignment in function again
376 * Fixed StaffGroup + GrandStaff combination.
378 * Music is now mandatory as the first thing in a \score{} block
385 * Implemented una-chorda and sostenuto piano pedals in performer and engraver.
387 * Added Properties textScriptWordSpace and chordNameWordSpace.
389 * Junked old lyrics in star-spangled-banner.
391 * Added a Piano_pedal_engraver.
393 * Removed some empty files.
395 * Created piano pedal symbols: * - . P e d.
397 * Fixed ps-to-pfa.py to handle multiple unfills.
399 * Moved accordion symbols out of feta-script to end of font.
401 * Bugfix: don't create tfm's, pfa's etc of feta-test fonts.
403 * Fixed blot_diameter for small resolutions.
408 * Put global element list into Line_of_score, instead of
409 Paper_score. post processing (the stage after line breaking) is now
410 truly done per-system, and we got rid of an ugly hack to get font
413 * Bugfix: set the group-interface of System_start_delimiter.
415 * Cleanups of Break_algorithm and derived classes, Move
416 broken_col_range () to Line_of_score, remove Paper_score::col_l_arr_
418 * Bugfix for accordion symbols.
420 * Various patches to prevent crashing when do_brew_molecule gets
421 called before after_line_breaking (). This was a problem in Spanner
430 * Made a quick try at piano pedal performer, damper pedal only.
432 * mf/feta-accordion.mf: Fixed strange turning paths.
434 * mf/feta-beugel.mf: Fixed infinity errors.
436 * Use a more discriptive name for windows setup.zip.
438 * mf/GNUmakefile: Have logs as last target, so that normally, they're
441 * stepmake/stepmake/metafont-rules.make: Don't remove the .log files.
442 The logs are a target, removing them retriggers make.
444 * stepmake/stepmake/metapost-rules.make: Remove the correct log and tfm
445 files, ie the ones that clutter the source directory, not the target logs.
447 * Windows distribution: faked symlink for cmtfm. Setup.zip should now be
448 standalone; ie, no need for Cygnus' usertools anymore.
453 * Documentation/ntweb: Updated angels.ly to match current syntax.
454 Also updated index.texi.
459 * Change all occurances of Staff_margin_engraver to
460 Instrument_name_engraver, add a convert-mudela rule
462 * Change status == busy assert into programming error
470 * Lots of fixes to windows distribution scripts.
472 * Added configuration features --program-prefix, --program suffix.
474 * lily/my-lily-parser.cc (get_chord): Bugfix, don't use deleted pitch.
475 This fixes inversions c/g and bass additions d/+c on chords.
480 * Avoid that xxxXXXVerticalExtent is used for empty HaraKiriStaff
486 * Debian patches (thanks Anthony!)
488 * Use symbols for prefatory matter spacing. Do not use the typename
489 for looking up item pairs in the table, but read element property
492 * Instrument_name_engraver, uses break alignment instead of
495 * System_start_delimiter_engraver, System_start_delimiter, uses a
496 spanner for the braces/brackets at the left of the system. Remove all
497 old Span_score_bar engravers.
499 * Removed Base_span_bar_engraver::use_prority_b_, and moved
500 Base_span_bar_engraver into Span_bar_engraver.
505 * mutopia/Coriolan/violino-2.ly: Bugfix: wrong pitch.
507 * input/test: Removed stale AutoStaffSwitch examples.
509 * mutopia/E.Satie: Fixed gnossiene-4, doing \autochange. Removed
510 stale copy of gnossiene-4.
512 * buildscripts/make-cygwin-cross.sh: Made some small .zip package fixes.
514 * make/lilypond.spec.in: Made some bugfixes for _prefix, preparations
515 for cross-building to Cygwin.
517 * buildscripts/make-cygwin-cross.sh: Now using rpm packages.
522 * added \property XXXMinimumVerticalExtent, \property XXXExtraVerticalExtent
524 * New_chord_tremolo_engraver: make tremolo beams from
526 \repeat "tremolo" NUMBER <Music-expression>
528 Removed support for "old-style" tremolos.
530 * Add a convert-mudela function for the conversion "\key A;" to "\key a;
532 * Read \property measurePosition within the engraver code, instead of
533 looking up the Timing_translator.
535 * star-spangled-banner.ly: add Bar_engraver to LyricsVoice
537 * Changed all .fly and .sly files to .ly files. Propose to dump .fly
546 * buildscripts/mf-to-table.py: feta dep files are now opened with write
547 binary option. This avoids carriage return linefeed problems and
548 windows while not affecting unix.
550 * Documentation/hacking.texi: Fixed a texinfo syntax error
552 * stepmake/bin/package-zip32.sh: Fixed or Removed some legacy, 1.2.x,
555 * Documentation/ntweb/index.texi: Fixed broken links, added 1.3.39 links.
560 * Glossary updates by Christian Mondrup.
562 * Bugfix: use generic properties in lyrics too. This fixes the
563 \property textStyle for lyrics.
565 * Score_element::preset_extent(), used by \property
566 XXXVerticalExtent, so hard code the size of a vertical group.
568 * Don't fix up reference points for originals of broken
569 spanners. Fixes spurious "orphaned score-element" warnings.
571 * buildscripts/make-cygwin-cross.sh: Use rx-1.5 instead of regex (Jeffrey).
573 * scm/lily.scm: Fixed check for Windows: by default don't use scm regex.
575 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: Significantly smaller
578 * buildscripts/make-cygwin-cross.sh: Compile native package GNU regex,
579 which should fix Windows problems with guile. Also added input directory
582 * stepmake/aclocal.m4: Added decent checking for version of guile, and
583 fixed warning message.
585 * lily/lexer.ll (My_lily_lexer): Bugfix: lookup chordmodifiers in the
586 chord-modifier table (not in the pitch list).
594 * General cleanups of My_lily_parser.
596 * Start of a Chord_tremolo_iterator for the `\repeat 4 "tremolo"'
599 * Moved Score_element::do_space_processing out of the dependency
602 * Use Scheme for notename tables. Removed uppercase letters for low
603 octave notes. Removed Notename_table.
605 * Fixed core dump with declared "\key ; "
607 * Extra robustness warning for Side_position_interface::aligned_on_self ()
609 * Extra robustness: make sure that first and last columns are breakable.
614 * stepmake/aclocal.m4: Added support for cross-compiling with guile.
616 * buildscripts/make-cygwin-cross.sh: A try at dropping cygwin1.dll
617 dependency by using mingw. Compiling guile is too much to ask
618 for mingw, though. Also:
619 - rename python scripts .py (request from Alain)
620 - install native packages under their own, separate root. (Alain)
622 * lily.scm: Don't use regex module when running on
625 * lily/staff-margin-engraver.cc (acknowledge_element): If
626 possible, hang y-axis of margin script to span-bar. This fixes
627 vertical placement of margin scripts attached to staff groups.
629 * help2man-rules.make: Fixes for generating manpages by copying
630 and for building using --scrdir.
632 * stepmake/stepmake/generic-targets.make: Preserve date stamp of
633 config.h, version.hh files file when copying.
635 * buildscripts/make-cygwin-cross.sh: made number of fixes:
636 - add `Cygnus/' prefix to directories in .zip-file too.
638 - don't link to cygwin1.dll
640 * stepmake/stepmake/install-targets.make: bugfix, don't fail if directory
641 is not emty when uninstalling.
643 * stepmake/stepmake/generic-targets.make: added man target.
645 * buildscripts/make-cygwin-cross.sh: new script for cross-building cygwin
646 development tools and lilypond executable.
648 * Documentation/ntweb/lilypond-manpages.patch: provide pre-built
649 manpages, so that make doesn't fail on help2man trying to execute
650 a GNU/windows executable.
652 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: new patch for
655 * flower/libc-extension.cc (memmem): cygwin compile fix.
663 * (generic-property.scm) added \property tieDash to set dashing on
666 * Removed ly_eval_str(), we should use scm_eval (Scm_object).
668 * Removed scm_to_array (), array_to_scm (), associated junk. Reverted
669 undocumented .29 patch that made Bezier::control_ into an
670 Array<Offset>. Added some comments documenting the reasons for the
673 * Revert generic-property.scm of .37 fix, fix the real problem in
674 property-engraver.cc: use the right symbol to check if element
675 property is already set.
680 * Fixed srcdir build, so that you can do:
682 tar xzf releases/lilypond-x.y.z
685 ../lilypond-x.y.z/configure
688 as with any other gnu package. All build output goes to <build>/out.
690 * Changed and fixed use of different configurations, and different output
691 directories. Finally, you can use different configurations alongside
692 eachother. From make/stepmake.make:
694 # Use alternate configurations alongside eachother:
696 # ./configure --enable-configsuffix=debug
699 # uses config-debug.make and config-debug.h; output goes to out-debug.
702 # Use same configuration, but different output directory:
706 # uses config.make and config.h; output goes to out-www.
710 * Fixed performance of (de)crescendi.
712 * Better documentation for arithmetic_multiplier and arithmetic_basicspace
715 * Added instrument-equaliser for MIDI output, see scm/midi.scm, and
716 properties midiMinimumVolume, midiMaximumVolume, ranges [0,1].
718 * Changed absolute midi volume settings into factor of full scale.
720 * Fixed another dynamic-line-spanner bug, it gets hairy.
722 * Added warning for spanners that are not fully contained in parent spanner.
730 * Abstract Align_element into Align_interface. Removed
731 Axis_align_{item,spanner}, Align_element, Super_element, all multiple
732 inheritance in the backend.
734 * new Gade score, INSTALL.texi fixes (thanks, Mats)
736 * Removed Item::hpos_f (), Score_element::{get,set}_real ()
738 * comments detailing properties for Axis_group_interface,
739 Side_position_interface, Score_element, Item and Spanner
744 * Fixed vertical dimensions of elements in dynamic line spanner by adding
745 axis-group to dynamic line spanner.
747 * Bugfix: line-spanner lasts always full duration of (de)crescendi.
749 * Bugfix: broken (de)crescendi on a dynamic-line-spanner.
751 * Bugfix: compilation dynamic-engraver.
753 * Added and updated a faq about postscript and ghostscript.
755 * Fixed order of slurVerticalDirection verticalDirection in
756 generic-property.scm. Similar fixes for Stem, Tie, etc.
758 * Added a Text_engraver to GraceContext. Maybe it was removed on
759 purpose: scripst on grace notes seem broken, they appear on the
762 * Bugfix: volume effect of (de)crescendi was sometimes wrong way round.
769 * textEmptyDimension changed into textNonEmpty, default: off,
770 ie. texts don't occupy space.
772 * Use STL map for Lookup::lookup_p_tab_p_
774 * Abstracted Axis_group_element into Axis_group_interface, and removed
775 Axis_group_element. This eliminates some multiple inheritance in the
781 * Added minimum-space property to Side_position_interface. Used in
782 positioning of Volta_spanner: voltaMinimumSpace.
784 * Fixed and cleaned-up volta-spanner.
786 * Moved directional-element.cc -> directional-element-interface.cc
788 * Renamed all `process_requests' to `process_music', which fixes
791 * Fixed dimensions (more x-y interchanges) of brace, bracket and
794 * Bit half-baken fix in to get similar vertical placement of orphaned vs.
795 line-spanned dynamic elements.
797 * Added property bracketCollapseHeight: the minimal size of a staff bracket
798 that will be typeset. Smaller brackets will not be displayed. This
799 fixes the (in 1.3.x reintroduced) funny duck-beak-bracket-bug (sorry).
801 * Removed some dissonant chords from Coriolan
806 * Removed Documentation/programmer directory
811 * Small enhancements to Staff_margin_engraver:
812 - by default, the marginScript left aligns the text
813 - to set the text style, use property marginScriptTextStyle
814 - to change the alignment, use property marginScriptHorizontalAlignment
815 (centred and right alignment require manual padding settings).
817 * Print a friendly message if the manual pages failed to build.
819 * Bugfix: dynamicDirection now overrides verticalDirection setting.
821 * Warning messages and nl.po
823 * Fixed vertical alignment for all dynamic items and (reluctantly)
824 reinstated old directional behaviour for orphaned dynamics.
826 * Finished maximumRestCount property.
833 * Print key without setting key, syntax "\key ;". General cleanups of
836 * Add paragraph tags in HTML output of mudela-book. Music fragment
837 don't run into the text anymore.
839 * Bugfix: don't align the first line of text. (Lookup::text ()).
841 * Abstract away data members of Axis_group_element, Align_element
847 * Added helpful properties instrumentScriptPadding/instrScriptPadding for
848 Staff_margin_engraver.
850 * Removed some empty files, substituted (c) 1999 occurrences.
852 * Added \property maximumRestCount. It will prevent showing (or actually:
853 moving in case of a collision) more than maximumRestCount similar rests.
856 * Rewrote Staff_margin_engraver. Staff margin texts now hang on a new
857 breakable item: Left_edge_item.
859 * Fixed vertical alignment for dynamic elements. Orphaned dynamic items
860 (not supported by a Dynamic_line_spanner) still collide with Staff,
861 although they now have staff support, which was supposed to fix this.
863 * Fixed Staff_margin_engraver for "instrument", "instr" is still broken.
865 * Dynamic elements are only put in a Dynamic_line_spanner if there
866 actually is more than one adjacent note-column with a dynamic.
867 This breaks the fine looks of all dynamics, again :-)
878 * Experiment: use STL map for Scheme_hash_table; Is there a speedup?
880 * Bugfix: print brace iso. bracket for Piano / GrandStaff
882 * Change naming: change do_post_processsing into after_line_breaking,
883 do_pre_processsing into before_line_breaking and do_process_requests
884 into do_process_music.
886 * Bugfix in hash-table.hh: do quadratic probing, and not cubic probing.
888 * Display property name for type error.
890 * Cleanups for Dynamic_engraver and Dynamic_line_spanner.
892 * Warn if last column in score is musical. Helps catch programming errors.
894 * Spanner::spanned_drul_ now is private.
896 * Rewrote some bar code: moved molecule functions out of Lookup.
901 * Embedded newlines in text items are now allowed. This helps avoiding
902 TeX-hacking in some cases. See input/test/coriolan-margin.ly
904 * Fixed stupid x-y interchange bug for staff-bracket. This fixes
905 placement of staff-brackets.
907 * Fixed bracket/arch-thickness interchange bug, and made bracket a bit
910 * Fixed slur/bezier-beautiful name mismatch. This should fix the steep
911 slurs that were apparently reintroduced in 1.3.29.
913 * Made some small fixes to Coriolan.
915 * Removed duplicate lily/output-property-engraver.hh.
917 * Removed optional use of vanilla spanner in Dynamic_engraver.
919 * Fixed (measured) tremolo for Stem and Beam. Merged declarations
920 stem-engraver.hh and chord-tremolo-engraver.hh into their .cc
921 implementation file. Also fixed looks of Chord tremolo, input and
922 implementation is still ugly.
924 * Added *.yy and *.ll to TAGS, to that tags-find-replace doesn't omit
930 * Fixed \specialkey and \normalkey. Updated documentation.
937 * Fixed and cleaned-up Dynamic_engraver. Optionionally uses vanilla
938 spanner instead of Dynamic_line_spanner.
940 * Made gcc-2.95 compile fix in libc-extension.
942 * Various fixes to Coriolan, score starts to look acceptable.
944 * Moved optional text of crescendo into Crescendo spanner. Fixed horizontal
945 and vertical alignment of dynamics.
947 * Added new text crescendo spanners to Coriolan and made some fixes.
948 If you're using timidity, use the -EO option to prevent notes get
949 stuck. I'm not sure whose fault this is, Lily's MIDI output may be
950 stretching the standard a bit.
952 * Adjacent dynamic markings are now grouped on a horizontal line, but it's
953 not perfect yet: they're always below the staff and no horizontal spacing
954 is done. Also, character metrics of dynamics are still not used.
955 See: input/test/crescendi.ly and input/test/dyn-line.ly
957 * Cleaned up Span_dynamic_performer.
964 * Fixed the page layout, reintroducing space for the header and
965 trying to keep piece titles on the same page as the piece.
966 The header and footer can now contain several lines.
971 * Lily now also performs crescendi and decrescendi in MIDI output:
972 Span_dynamic_performer (bit scrappy).
974 * Added preliminary support for crescendi/decrescendi other than `hairpins',
975 eg: `cresc. poco `a poco -- -- --'
977 * Made MIDI tie performance fix.
982 * Lily now performs absolute dynamics in MIDI output.
984 * Included David's comments on opus47 in TODO.
989 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
990 fixes and remainder french horn-1,2; trombone-1,2;
991 fagotto-1,2; timpani; and several fixes.
996 * Remove some old doco from programmer/ and put on personal homepage.
998 * Removed union-find from flower library.
1000 * Only quantise tie horizontal part inside the staff.
1007 * Report type errors for \property. Helps with converting 1.2 input
1009 * Use Scheme for Align_element; fixed graceAlignPosition
1010 and removed \property alignmentReference in the process.
1012 * Use generic properties for lyrics too. This fixes \property
1016 * Add relative distance for constraints between non-column items.
1018 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
1019 increased automatically.
1021 * Translators now only change properties of their own context. This
1022 removes the 2nd argument to Translator::get_property()
1024 * Bugfix for Metapost mode
1029 * Updates of glossary (Christian Mondrup)
1031 * Bugfix with bar number placement
1033 * Moved links to bibliography/ and misc/ to main index.
1038 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
1039 Slurs are now calculated just once.
1041 * Bezier_bow gets constants from paper. Still no sensible solution for
1042 magic asymmetry gradient step constants.
1044 * Reinstantiated tangent-controls, more flexible than ever. You can choose
1045 between area asymmetry and tangent-controls. My guess is, tangent controls
1046 will be junked in 1.3.30.
1048 * Slur area: only look at x-gradient.
1050 * Added credits for some symbols of as5/9 fonts.
1052 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
1054 * Bugfix: midi2ly put out recent version (ugh).
1059 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
1062 * Removed Gade score. To appear (shortly?) on Mutopia.
1064 * Make Bar_script_engraver look for typeVisibilityFunction (eg
1065 property barNumberVisibilityFunction). Changed the names of the Scheme
1066 functions to be understandable. See input/test/bar-script-visibility.ly
1068 * rewrite of class Molecule. It has now reached the ultimate quality
1069 plateau. All molecule data is now shared.
1074 * Update of the glossary by Christian Mondrup
1076 * Moved horn-concerto-3 out of tarball to private website, removed
1077 W.A.Mozart subdirectory.
1082 * Bugfix: don't make giant ties if the horizontal part of tie is near
1085 * Small optimizations to be a little more careful with mem usage.
1087 * Website change: put all examples in one directory.
1089 * Removed Atom as a separate type. Now use SCM, and since we use
1090 function composition, Atoms are immutable, so they don't have to be
1091 copied. This makes life easier, hopefully this is quicker and uses
1097 * Bezier_bow: minimise_enclosed_area
1105 * Tuplet-spanner slope calculation now looks better on tupletted rests
1106 (patch courtesy Laurent Martelli)
1108 * Bugfix (Staff_performer::new_instrument_str ()) check type of
1109 \property "instrument"
1111 * New mechanism for breaking lines: do not copy & prune the element
1112 property list separately, but combine these steps. Dramatically
1113 reduces memory usage for large scores.
1120 * Bugfix: font used in volta-spanner calculation.
1122 * Added simple selection list to webpage, inspired by sawmill.
1124 * Devised kludge for ascii 5 character font pitches.
1126 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
1131 * Plug memory leaks related to Moment:
1132 - Spacing_engraver::do_pre_move_processing ()
1133 - make_rational ()/make-rational
1134 - Paper_column::Paper_column ()
1136 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
1138 * Plug memory leak in Score_engraver::set_columns ()
1140 * Plug memory leak in Scheme_hash_table::set()
1142 * Plug memory leak in Score_element::molecule_extent ()
1144 * Bugfix: don't crash if a slur doesn't span anything.
1146 * Bugfix: don't crash if doing beams without a staff symbol.
1148 * Generic element property setting:
1150 \outputproperty #predicate #'symbol = #value
1152 Will set the element property symbol to value, for any elements that
1153 return true for PREDICATE. This allows you to virtually tweak *ANY*
1154 property of the output. Example in input/test/generic-output-property.ly
1159 * lilypond as as2ly: --help and --version to stdout. Regular identify
1160 to stderr. This fixes help2man's manpage generation.
1162 * configure: substitute full path for perl and guile in scripts.
1164 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
1166 * Bugfix: default font now user settable
1168 * as2text: handle plain ascii font, read from stdin, you can now do:
1170 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
1175 * Bugfix: second half of broken ties now are displayed again.
1177 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
1178 it horizontally on the clef.
1180 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
1182 * Bugfix: unbroken repeat barlines now work, eg. |:
1184 * Added Request_iterator to make more flexible constructions possible.
1188 * as2text: catch missing font/character errors, added default font, set text.
1190 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
1192 * Ascii output, minimal support:
1193 - AsciiScript Fonts: mf/*.af
1194 - Init files: ly/*-as.*ly
1195 - AsciiScript translation to text: scripts/as2text.scm
1196 - input/test/as.fly input/test/as1.fly
1197 - Output support: lily/lily.scm
1199 lilypond -f as -i init-as.fly input/test/as.fly
1205 * The horizontal part of ties will avoid collision with staff lines.
1207 * Plugged memory leak: don't protect Atom function.
1209 * Lookup cleanups. Made lots of functions static. Moved some code out
1217 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
1218 does not delete any of the file_ly*.tex.
1220 * Added header and footer support in ly2dvi.py
1225 * Added a ROADMAP file explaining the source directory layout.
1227 * Minor tweak in the feta 6 and 9 numeral
1229 * Moved files from lib/ to flower/
1231 * Removed Note_head_side class.
1233 * Updated the webpage to be a little more chatty.
1235 * Small Local_key_engraver optimization: only lookup timing engraver once.
1237 * Fixed dashed slurs
1239 * Rewrite of Slur code. Be much more picky about slur shapes. We try
1240 to offset the slur instead of bending it too much
1242 * Look at stem directions for tie direction.
1244 * Compound multimeasure rests. Put measures_i_ variable in an element
1245 property. Made the symbol a lot wider.
1247 * Time signature small cleanups.
1252 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
1255 * Breathing marks now have a direction by default.
1257 * Do set generic script properties.
1259 * Also put tuplet brackets under notes.
1261 * Score_element_info: only store origin of element, but not the path
1262 to parent translators. Saves a little memory, and removes some complexity.
1268 * Autobeaming in time sigs that don't have 1/4 beats fixed.
1270 * (De)crescendi should now work. (Thanks Michael)
1272 * Better error reporting for conflicting time signatures.
1274 * Line_number_engraver: output locations of note head
1275 definitions. Very handy when entering complicated scores.
1277 * Rewrote multi measure rest support: now they are entered as spanners
1278 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
1280 { \commandspanrequest \start "rest"
1282 \commandspanrequest \stop "rest"
1285 * Removed support of percent style repetitions.
1287 * Put texts outside the staff.
1291 * Getopt bugfix: don't assert on certain errors.
1293 * ly2dvi: Remove unnecessary space for the page headers.
1295 * Bugfix convert-mudela
1300 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
1303 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
1304 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
1305 \property tupletInvisible will stop all tuplet spanner creation.
1307 * Don't go berserk if tuplet spanner is on only one column.
1309 * Use SCMs & Smobs for Molecules & atoms. This uses less
1310 scm_(un)protect_object () calls, so the output stage should be faster.
1312 * Added \property tupletSpannerDuration, to make multiple tuplet signs
1315 * Some programming Errors in spacing are now caught. Lily does not
1316 hang when encountering degenerate springs.
1318 * Allow beams to start and end over rests
1322 * Fix disappearing clefs when clefs are not printed with a barline.
1327 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
1328 input/test/beam-control.fly
1329 * Added \context Voice to .fly and .sly; the default \context Staff is almost
1330 never what you expect
1331 * Fixed decision for .sly/.fly in lilypond-mode.
1336 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
1337 Cleanup mf-to-table.py
1339 * Fixed embarassing slur bug.
1344 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
1349 * lilypond-mode.el for emacs supersedes mudela-mode.el
1351 * Tuplet spanners don't collide with encompassing notes.
1353 * Gobbled Adobe parseAFM* code, for future use.
1355 * Big 1999 to 2000 search/replace.
1357 * Big interline to staff_space search/replace for mf files.
1359 * Removed Bow class, and split code into Tie and Slur
1361 * Don't put scripts on grace notes.
1363 * Font_metric uses SCM for name field.
1365 * Various compilation fixes.
1370 * Bugfix: beams with less than one (visible) stem
1372 * small fixes to pa.ly
1377 * Fixed bug that made multi-measure rest barnumber counts go wild.
1378 (even more scm2int/int2scm mixups!)
1380 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
1382 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
1387 * Remove Paper_def calls in bezier-bow.cc
1389 * Remove data members of Tuplet_spanner, Volta_spanner
1391 * hang_on_clef, property hangOnClef removed
1393 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
1394 function to determine breaking behavior.
1396 * More Scheme typechecking.
1398 * Be strict about the difference between strings and symbols for conversion.
1400 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
1403 * Partial French translation, courtesy Laurent Martelli.
1405 * Small corrections in NL translation.
1410 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
1411 we have a longa note head. noteHeadStyle = "harmonic" is not
1412 supported anymore. (for now, that is)
1414 * Reference manual update. Document \properties with examples
1416 * fix mudela-book --help
1418 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
1419 Key_item::c0_position_
1421 * Clef_engraver general cleanup. Use alists (\property
1422 supportedClefTypes, clefPitches) for clef types.
1424 * Use progress_indication () for progress. Don't include <iostream.h> directly
1425 Don't include <string.h>, <math.h> from headers.
1431 * \property stemCentered (boolean): centers stem on note head. See
1432 input/test/stem-centered.ly
1434 * input/trip.ly, small test of lots of features.
1436 * \property Staff.collisionMergeDotted: merge equal noteheads
1437 with different dot count. See input/test/collision-merge-dotted.fly
1439 * Dotted rest bugfix
1441 * Don't crash if a slur does not span any notes.
1443 * Volta repeats fixed.
1445 * cleanup of Note_heads_engraver
1447 * removed dots_i_ member of Dots
1451 * Fixed cross staff slurs. It seems that cross-staff sign
1457 * Fixed bug in stem code. Stem in chords works again. Small
1460 * Use element properties for Staff_symbol.
1462 * \property sparseTies (boolean). Only make one tie in the
1463 middle for tied chords.
1465 * Junked Directional_spanner, Column_info.
1466 Directional_element now is element interface `Directional_element_interface'
1468 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
