2 ++ b/CHANGES Thu May 25 23:22:02 2000
9 * Added scripts/linux-time.py: simple utility to monitor memory (and later
10 maybe other) resource usage from Linux's proc fs.
17 * Massive search replace patch: store pointers and properties
18 separately, in preparation of property collapse.
23 * Bugfix: don't crash on tuplet spanners that don't contain any notes.
25 * Small cleanup of Dimension_cache: removed a few redundant
26 fields. Slightly lower memory usage. Dimension_cache is now a `dumb'
29 * Add array index to priority field of text scripts to ensure that
30 order is unique, and sensible.
32 * Added an element count statistic.
37 * russian.po (thank you, August.)
39 * Small cleanups in Molecule interface
41 * Spacing related elements perform suicide after calculating
42 distances. This saves a some memory, approximately 2 to 5 % ?
44 * Small cleanups in line breaking: Paper_column stores springs and
45 rods in only one place now. All fields relating to energy have been
48 * Don't generate all output Scheme in memory, but evaluate to output
49 file immediately. This will reduce memory usage a little.
51 * Use STL's map for Dictionary template
53 * Substitute pointers on element properties of the root Line_of_score
56 * Added toplevel doc target, to support building doc with --srcdir
58 * Removed cygwin build stuff; updated versions at:
60 http://appel.dyndns.org/lilypond/gnu-windows/cross
62 * Fixed lily.scm to handle incipits (thanks, Mats)
68 * Made bugfix in smob handling: delete the C-part of freed smobs and
69 be honest about amount of allocation and deletion, so that GUILE
70 doesn't overestimate the amount of memory available.
72 * Faq update: nicer blank note paper, courtesy Mats Bengtsson.
74 * Bugfix: don't crash on durations that are not a power of 2.
76 * Build manpages during `make all'
78 * Bugfix: don't do absolute comparisons in Polynomial::clean ().
80 * Bugfix: set visibility-lambda for key signature created by
81 createKeyOnClefChange. Fixes disappearing key signatures.
83 * Bugfix: make System_start_delimiter of bar-line type invisible when
84 it spans only one staff.
89 * Item cleanups. Copying items and rearranging pointers are done in
90 separate passes, which makes the code cleaner. This fixes a problem
91 with some items not disappearing from hara-kiri staffs.
93 * Use Scheme for Key_item data members.
95 * Don't use regex in chord-names.scm under windows; hybrid chordnames
96 user+calculated will be partly broken.
101 * Junked Shift_tuple from collision; Now it uses SCM.
103 * Bugfix of documentation and test-file of tuplet.
105 * Bugfix type string of repeated music is copied. This fixes declared
108 * Junked various cruft from lily.scm
110 * Use interfaces symbols instead of C++ class-name for assigning generic
113 * Junked Dictionary from Piano_pedal_engraver and
114 Piano_pedal_performer.
116 * Introduced boolean element property no-spacing-rods: ignore this
117 item for hard constraints.
119 * Bugfix: added sanitised TeX fragment in faq.texi
121 * Bugfix: merge equal Bar_reqs
126 * Small fixes for \cresc and \endcresc
128 * Release properties of unbroken spanners & items after doing
129 handle_broken_smobs (); should conserve a little memory.
131 * Fixed handling of orphaned score-elements. Any element that does
132 not have its Line_of_score as a ancestor in both directions, is silently
133 removed from the output. This guarantees that programming errors
134 don't result in coredumps from Dimension_cache::common_refpoint ():
135 element->line_l () is always a common reference point.
137 * Bugfix: set visibility-lambda of clef and octavation-8 explicitly
138 for default case. Now the octavation 8 is not printed at every
144 * Changed noteHeadStyle properties to symbols, for example
145 \property Voice.noteHeadStyle = #'cross
150 * Rewrite of chord-name production in scheme. There are two major styles
151 now, banter and american. To get american style, use
153 \property ChordNames.chordNameStyle = "american"
155 Most anything should be possible now. See input/test/american-chords.ly
157 * Added isinf check to configure.in, and isinf macro from guile to
158 bezier.cc; solaris has no isinf ().
160 * Fixed star-spangled-banner with not-so-nice \bar "|." fix. Almost
163 * Added output property to regression test.
165 * Fixed warning of creating existing outdir.
167 * Added `Mark' interface to text-items that are marks (thanks, HW).
174 * Corrected glossary.tely
176 * Corrected \mark font handling. feta-nummer font only of the
177 string is all numeric.
179 * Implemented noteHeadStyle lookup in Guile. Reintroduced the style
180 "harmonic" and added "baroque" (normal note shapes except for
181 brevis and longa which are square).
183 * Simplified ly2dvi using the power of the geometry package.
185 * Improved heuristic size calculation of TeX macros. Handles e.g.
186 "\\u{a}", "\\"{o}" and "\\^{u}" correctly.
191 * Bugfix: don't hang on zero-duration.
193 * Various glossary updates (thanks, Christian)
201 * Drastically reduced vertical space used by headers/footers, when using
202 ly2dvi. See input/test/fill-a4.ly.
204 * Fixed bug with colons appearing on repeat span-bars.
206 * Added Bar_number_engraver to standard Score context
208 * Construct octavation scripts in the clef-engraver; this fixes the
209 hara-kiri + clef8 problem
217 * Fixed chord-name customisation and made small chord-name build fixes.
219 * Accidentals with chord-names smaller and as superscript.
221 * Do some extra footify (works only once) while making html docs.
226 * Debian patch (Thanks Anthony)
228 * Rewrote Bar_number_engraver and Mark_engraver and removed
229 Bar_script_engraver as baseclass. Both Bar_number_engraver and
230 Mark_engraver are simpler and more robust.
232 * Fixed precedence of \property verticalDirection and dynamicDirection
234 * Fixed keys without barlines
236 * Fixed StaffGroups: removing `\consistsend "Axis_group_engraver"'
237 puts alignment in function again
239 * Fixed StaffGroup + GrandStaff combination.
241 * Music is now mandatory as the first thing in a \score{} block
248 * Implemented una-chorda and sostenuto piano pedals in performer and engraver.
250 * Added Properties textScriptWordSpace and chordNameWordSpace.
252 * Junked old lyrics in star-spangled-banner.
254 * Added a Piano_pedal_engraver.
256 * Removed some empty files.
258 * Created piano pedal symbols: * - . P e d.
260 * Fixed ps-to-pfa.py to handle multiple unfills.
262 * Moved accordion symbols out of feta-script to end of font.
264 * Bugfix: don't create tfm's, pfa's etc of feta-test fonts.
266 * Fixed blot_diameter for small resolutions.
271 * Put global element list into Line_of_score, instead of
272 Paper_score. post processing (the stage after line breaking) is now
273 truly done per-system, and we got rid of an ugly hack to get font
276 * Bugfix: set the group-interface of System_start_delimiter.
278 * Cleanups of Break_algorithm and derived classes, Move
279 broken_col_range () to Line_of_score, remove Paper_score::col_l_arr_
281 * Bugfix for accordion symbols.
283 * Various patches to prevent crashing when do_brew_molecule gets
284 called before after_line_breaking (). This was a problem in Spanner
293 * Made a quick try at piano pedal performer, damper pedal only.
295 * mf/feta-accordion.mf: Fixed strange turning paths.
297 * mf/feta-beugel.mf: Fixed infinity errors.
299 * Use a more discriptive name for windows setup.zip.
301 * mf/GNUmakefile: Have logs as last target, so that normally, they're
304 * stepmake/stepmake/metafont-rules.make: Don't remove the .log files.
305 The logs are a target, removing them retriggers make.
307 * stepmake/stepmake/metapost-rules.make: Remove the correct log and tfm
308 files, ie the ones that clutter the source directory, not the target logs.
310 * Windows distribution: faked symlink for cmtfm. Setup.zip should now be
311 standalone; ie, no need for Cygnus' usertools anymore.
316 * Documentation/ntweb: Updated angels.ly to match current syntax.
317 Also updated index.texi.
322 * Change all occurances of Staff_margin_engraver to
323 Instrument_name_engraver, add a convert-mudela rule
325 * Change status == busy assert into programming error
333 * Lots of fixes to windows distribution scripts.
335 * Added configuration features --program-prefix, --program suffix.
337 * lily/my-lily-parser.cc (get_chord): Bugfix, don't use deleted pitch.
338 This fixes inversions c/g and bass additions d/+c on chords.
343 * Avoid that xxxXXXVerticalExtent is used for empty HaraKiriStaff
349 * Debian patches (thanks Anthony!)
351 * Use symbols for prefatory matter spacing. Do not use the typename
352 for looking up item pairs in the table, but read element property
355 * Instrument_name_engraver, uses break alignment instead of
358 * System_start_delimiter_engraver, System_start_delimiter, uses a
359 spanner for the braces/brackets at the left of the system. Remove all
360 old Span_score_bar engravers.
362 * Removed Base_span_bar_engraver::use_prority_b_, and moved
363 Base_span_bar_engraver into Span_bar_engraver.
368 * mutopia/Coriolan/violino-2.ly: Bugfix: wrong pitch.
370 * input/test: Removed stale AutoStaffSwitch examples.
372 * mutopia/E.Satie: Fixed gnossiene-4, doing \autochange. Removed
373 stale copy of gnossiene-4.
375 * buildscripts/make-cygwin-cross.sh: Made some small .zip package fixes.
377 * make/lilypond.spec.in: Made some bugfixes for _prefix, preparations
378 for cross-building to Cygwin.
380 * buildscripts/make-cygwin-cross.sh: Now using rpm packages.
385 * added \property XXXMinimumVerticalExtent, \property XXXExtraVerticalExtent
387 * New_chord_tremolo_engraver: make tremolo beams from
389 \repeat "tremolo" NUMBER <Music-expression>
391 Removed support for "old-style" tremolos.
393 * Add a convert-mudela function for the conversion "\key A;" to "\key a;
395 * Read \property measurePosition within the engraver code, instead of
396 looking up the Timing_translator.
398 * star-spangled-banner.ly: add Bar_engraver to LyricsVoice
400 * Changed all .fly and .sly files to .ly files. Propose to dump .fly
409 * buildscripts/mf-to-table.py: feta dep files are now opened with write
410 binary option. This avoids carriage return linefeed problems and
411 windows while not affecting unix.
413 * Documentation/hacking.texi: Fixed a texinfo syntax error
415 * stepmake/bin/package-zip32.sh: Fixed or Removed some legacy, 1.2.x,
418 * Documentation/ntweb/index.texi: Fixed broken links, added 1.3.39 links.
423 * Glossary updates by Christian Mondrup.
425 * Bugfix: use generic properties in lyrics too. This fixes the
426 \property textStyle for lyrics.
428 * Score_element::preset_extent(), used by \property
429 XXXVerticalExtent, so hard code the size of a vertical group.
431 * Don't fix up reference points for originals of broken
432 spanners. Fixes spurious "orphaned score-element" warnings.
434 * buildscripts/make-cygwin-cross.sh: Use rx-1.5 instead of regex (Jeffrey).
436 * scm/lily.scm: Fixed check for Windows: by default don't use scm regex.
438 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: Significantly smaller
441 * buildscripts/make-cygwin-cross.sh: Compile native package GNU regex,
442 which should fix Windows problems with guile. Also added input directory
445 * stepmake/aclocal.m4: Added decent checking for version of guile, and
446 fixed warning message.
448 * lily/lexer.ll (My_lily_lexer): Bugfix: lookup chordmodifiers in the
449 chord-modifier table (not in the pitch list).
457 * General cleanups of My_lily_parser.
459 * Start of a Chord_tremolo_iterator for the `\repeat 4 "tremolo"'
462 * Moved Score_element::do_space_processing out of the dependency
465 * Use Scheme for notename tables. Removed uppercase letters for low
466 octave notes. Removed Notename_table.
468 * Fixed core dump with declared "\key ; "
470 * Extra robustness warning for Side_position_interface::aligned_on_self ()
472 * Extra robustness: make sure that first and last columns are breakable.
477 * stepmake/aclocal.m4: Added support for cross-compiling with guile.
479 * buildscripts/make-cygwin-cross.sh: A try at dropping cygwin1.dll
480 dependency by using mingw. Compiling guile is too much to ask
481 for mingw, though. Also:
482 - rename python scripts .py (request from Alain)
483 - install native packages under their own, separate root. (Alain)
485 * lily.scm: Don't use regex module when running on
488 * lily/staff-margin-engraver.cc (acknowledge_element): If
489 possible, hang y-axis of margin script to span-bar. This fixes
490 vertical placement of margin scripts attached to staff groups.
492 * help2man-rules.make: Fixes for generating manpages by copying
493 and for building using --scrdir.
495 * stepmake/stepmake/generic-targets.make: Preserve date stamp of
496 config.h, version.hh files file when copying.
498 * buildscripts/make-cygwin-cross.sh: made number of fixes:
499 - add `Cygnus/' prefix to directories in .zip-file too.
501 - don't link to cygwin1.dll
503 * stepmake/stepmake/install-targets.make: bugfix, don't fail if directory
504 is not emty when uninstalling.
506 * stepmake/stepmake/generic-targets.make: added man target.
508 * buildscripts/make-cygwin-cross.sh: new script for cross-building cygwin
509 development tools and lilypond executable.
511 * Documentation/ntweb/lilypond-manpages.patch: provide pre-built
512 manpages, so that make doesn't fail on help2man trying to execute
513 a GNU/windows executable.
515 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: new patch for
518 * flower/libc-extension.cc (memmem): cygwin compile fix.
526 * (generic-property.scm) added \property tieDash to set dashing on
529 * Removed ly_eval_str(), we should use scm_eval (Scm_object).
531 * Removed scm_to_array (), array_to_scm (), associated junk. Reverted
532 undocumented .29 patch that made Bezier::control_ into an
533 Array<Offset>. Added some comments documenting the reasons for the
536 * Revert generic-property.scm of .37 fix, fix the real problem in
537 property-engraver.cc: use the right symbol to check if element
538 property is already set.
543 * Fixed srcdir build, so that you can do:
545 tar xzf releases/lilypond-x.y.z
548 ../lilypond-x.y.z/configure
551 as with any other gnu package. All build output goes to <build>/out.
553 * Changed and fixed use of different configurations, and different output
554 directories. Finally, you can use different configurations alongside
555 eachother. From make/stepmake.make:
557 # Use alternate configurations alongside eachother:
559 # ./configure --enable-configsuffix=debug
562 # uses config-debug.make and config-debug.h; output goes to out-debug.
565 # Use same configuration, but different output directory:
569 # uses config.make and config.h; output goes to out-www.
573 * Fixed performance of (de)crescendi.
575 * Better documentation for arithmetic_multiplier and arithmetic_basicspace
578 * Added instrument-equaliser for MIDI output, see scm/midi.scm, and
579 properties midiMinimumVolume, midiMaximumVolume, ranges [0,1].
581 * Changed absolute midi volume settings into factor of full scale.
583 * Fixed another dynamic-line-spanner bug, it gets hairy.
585 * Added warning for spanners that are not fully contained in parent spanner.
593 * Abstract Align_element into Align_interface. Removed
594 Axis_align_{item,spanner}, Align_element, Super_element, all multiple
595 inheritance in the backend.
597 * new Gade score, INSTALL.texi fixes (thanks, Mats)
599 * Removed Item::hpos_f (), Score_element::{get,set}_real ()
601 * comments detailing properties for Axis_group_interface,
602 Side_position_interface, Score_element, Item and Spanner
607 * Fixed vertical dimensions of elements in dynamic line spanner by adding
608 axis-group to dynamic line spanner.
610 * Bugfix: line-spanner lasts always full duration of (de)crescendi.
612 * Bugfix: broken (de)crescendi on a dynamic-line-spanner.
614 * Bugfix: compilation dynamic-engraver.
616 * Added and updated a faq about postscript and ghostscript.
618 * Fixed order of slurVerticalDirection verticalDirection in
619 generic-property.scm. Similar fixes for Stem, Tie, etc.
621 * Added a Text_engraver to GraceContext. Maybe it was removed on
622 purpose: scripst on grace notes seem broken, they appear on the
625 * Bugfix: volume effect of (de)crescendi was sometimes wrong way round.
632 * textEmptyDimension changed into textNonEmpty, default: off,
633 ie. texts don't occupy space.
635 * Use STL map for Lookup::lookup_p_tab_p_
637 * Abstracted Axis_group_element into Axis_group_interface, and removed
638 Axis_group_element. This eliminates some multiple inheritance in the
644 * Added minimum-space property to Side_position_interface. Used in
645 positioning of Volta_spanner: voltaMinimumSpace.
647 * Fixed and cleaned-up volta-spanner.
649 * Moved directional-element.cc -> directional-element-interface.cc
651 * Renamed all `process_requests' to `process_music', which fixes
654 * Fixed dimensions (more x-y interchanges) of brace, bracket and
657 * Bit half-baken fix in to get similar vertical placement of orphaned vs.
658 line-spanned dynamic elements.
660 * Added property bracketCollapseHeight: the minimal size of a staff bracket
661 that will be typeset. Smaller brackets will not be displayed. This
662 fixes the (in 1.3.x reintroduced) funny duck-beak-bracket-bug (sorry).
664 * Removed some dissonant chords from Coriolan
669 * Removed Documentation/programmer directory
674 * Small enhancements to Staff_margin_engraver:
675 - by default, the marginScript left aligns the text
676 - to set the text style, use property marginScriptTextStyle
677 - to change the alignment, use property marginScriptHorizontalAlignment
678 (centred and right alignment require manual padding settings).
680 * Print a friendly message if the manual pages failed to build.
682 * Bugfix: dynamicDirection now overrides verticalDirection setting.
684 * Warning messages and nl.po
686 * Fixed vertical alignment for all dynamic items and (reluctantly)
687 reinstated old directional behaviour for orphaned dynamics.
689 * Finished maximumRestCount property.
696 * Print key without setting key, syntax "\key ;". General cleanups of
699 * Add paragraph tags in HTML output of mudela-book. Music fragment
700 don't run into the text anymore.
702 * Bugfix: don't align the first line of text. (Lookup::text ()).
704 * Abstract away data members of Axis_group_element, Align_element
710 * Added helpful properties instrumentScriptPadding/instrScriptPadding for
711 Staff_margin_engraver.
713 * Removed some empty files, substituted (c) 1999 occurrences.
715 * Added \property maximumRestCount. It will prevent showing (or actually:
716 moving in case of a collision) more than maximumRestCount similar rests.
719 * Rewrote Staff_margin_engraver. Staff margin texts now hang on a new
720 breakable item: Left_edge_item.
722 * Fixed vertical alignment for dynamic elements. Orphaned dynamic items
723 (not supported by a Dynamic_line_spanner) still collide with Staff,
724 although they now have staff support, which was supposed to fix this.
726 * Fixed Staff_margin_engraver for "instrument", "instr" is still broken.
728 * Dynamic elements are only put in a Dynamic_line_spanner if there
729 actually is more than one adjacent note-column with a dynamic.
730 This breaks the fine looks of all dynamics, again :-)
741 * Experiment: use STL map for Scheme_hash_table; Is there a speedup?
743 * Bugfix: print brace iso. bracket for Piano / GrandStaff
745 * Change naming: change do_post_processsing into after_line_breaking,
746 do_pre_processsing into before_line_breaking and do_process_requests
747 into do_process_music.
749 * Bugfix in hash-table.hh: do quadratic probing, and not cubic probing.
751 * Display property name for type error.
753 * Cleanups for Dynamic_engraver and Dynamic_line_spanner.
755 * Warn if last column in score is musical. Helps catch programming errors.
757 * Spanner::spanned_drul_ now is private.
759 * Rewrote some bar code: moved molecule functions out of Lookup.
764 * Embedded newlines in text items are now allowed. This helps avoiding
765 TeX-hacking in some cases. See input/test/coriolan-margin.ly
767 * Fixed stupid x-y interchange bug for staff-bracket. This fixes
768 placement of staff-brackets.
770 * Fixed bracket/arch-thickness interchange bug, and made bracket a bit
773 * Fixed slur/bezier-beautiful name mismatch. This should fix the steep
774 slurs that were apparently reintroduced in 1.3.29.
776 * Made some small fixes to Coriolan.
778 * Removed duplicate lily/output-property-engraver.hh.
780 * Removed optional use of vanilla spanner in Dynamic_engraver.
782 * Fixed (measured) tremolo for Stem and Beam. Merged declarations
783 stem-engraver.hh and chord-tremolo-engraver.hh into their .cc
784 implementation file. Also fixed looks of Chord tremolo, input and
785 implementation is still ugly.
787 * Added *.yy and *.ll to TAGS, to that tags-find-replace doesn't omit
793 * Fixed \specialkey and \normalkey. Updated documentation.
800 * Fixed and cleaned-up Dynamic_engraver. Optionionally uses vanilla
801 spanner instead of Dynamic_line_spanner.
803 * Made gcc-2.95 compile fix in libc-extension.
805 * Various fixes to Coriolan, score starts to look acceptable.
807 * Moved optional text of crescendo into Crescendo spanner. Fixed horizontal
808 and vertical alignment of dynamics.
810 * Added new text crescendo spanners to Coriolan and made some fixes.
811 If you're using timidity, use the -EO option to prevent notes get
812 stuck. I'm not sure whose fault this is, Lily's MIDI output may be
813 stretching the standard a bit.
815 * Adjacent dynamic markings are now grouped on a horizontal line, but it's
816 not perfect yet: they're always below the staff and no horizontal spacing
817 is done. Also, character metrics of dynamics are still not used.
818 See: input/test/crescendi.ly and input/test/dyn-line.ly
820 * Cleaned up Span_dynamic_performer.
827 * Fixed the page layout, reintroducing space for the header and
828 trying to keep piece titles on the same page as the piece.
829 The header and footer can now contain several lines.
834 * Lily now also performs crescendi and decrescendi in MIDI output:
835 Span_dynamic_performer (bit scrappy).
837 * Added preliminary support for crescendi/decrescendi other than `hairpins',
838 eg: `cresc. poco `a poco -- -- --'
840 * Made MIDI tie performance fix.
845 * Lily now performs absolute dynamics in MIDI output.
847 * Included David's comments on opus47 in TODO.
852 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
853 fixes and remainder french horn-1,2; trombone-1,2;
854 fagotto-1,2; timpani; and several fixes.
859 * Remove some old doco from programmer/ and put on personal homepage.
861 * Removed union-find from flower library.
863 * Only quantise tie horizontal part inside the staff.
870 * Report type errors for \property. Helps with converting 1.2 input
872 * Use Scheme for Align_element; fixed graceAlignPosition
873 and removed \property alignmentReference in the process.
875 * Use generic properties for lyrics too. This fixes \property
879 * Add relative distance for constraints between non-column items.
881 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
882 increased automatically.
884 * Translators now only change properties of their own context. This
885 removes the 2nd argument to Translator::get_property()
887 * Bugfix for Metapost mode
892 * Updates of glossary (Christian Mondrup)
894 * Bugfix with bar number placement
896 * Moved links to bibliography/ and misc/ to main index.
901 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
902 Slurs are now calculated just once.
904 * Bezier_bow gets constants from paper. Still no sensible solution for
905 magic asymmetry gradient step constants.
907 * Reinstantiated tangent-controls, more flexible than ever. You can choose
908 between area asymmetry and tangent-controls. My guess is, tangent controls
909 will be junked in 1.3.30.
911 * Slur area: only look at x-gradient.
913 * Added credits for some symbols of as5/9 fonts.
915 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
917 * Bugfix: midi2ly put out recent version (ugh).
922 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
925 * Removed Gade score. To appear (shortly?) on Mutopia.
927 * Make Bar_script_engraver look for typeVisibilityFunction (eg
928 property barNumberVisibilityFunction). Changed the names of the Scheme
929 functions to be understandable. See input/test/bar-script-visibility.ly
931 * rewrite of class Molecule. It has now reached the ultimate quality
932 plateau. All molecule data is now shared.
937 * Update of the glossary by Christian Mondrup
939 * Moved horn-concerto-3 out of tarball to private website, removed
940 W.A.Mozart subdirectory.
945 * Bugfix: don't make giant ties if the horizontal part of tie is near
948 * Small optimizations to be a little more careful with mem usage.
950 * Website change: put all examples in one directory.
952 * Removed Atom as a separate type. Now use SCM, and since we use
953 function composition, Atoms are immutable, so they don't have to be
954 copied. This makes life easier, hopefully this is quicker and uses
960 * Bezier_bow: minimise_enclosed_area
968 * Tuplet-spanner slope calculation now looks better on tupletted rests
969 (patch courtesy Laurent Martelli)
971 * Bugfix (Staff_performer::new_instrument_str ()) check type of
972 \property "instrument"
974 * New mechanism for breaking lines: do not copy & prune the element
975 property list separately, but combine these steps. Dramatically
976 reduces memory usage for large scores.
983 * Bugfix: font used in volta-spanner calculation.
985 * Added simple selection list to webpage, inspired by sawmill.
987 * Devised kludge for ascii 5 character font pitches.
989 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
994 * Plug memory leaks related to Moment:
995 - Spacing_engraver::do_pre_move_processing ()
996 - make_rational ()/make-rational
997 - Paper_column::Paper_column ()
999 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
1001 * Plug memory leak in Score_engraver::set_columns ()
1003 * Plug memory leak in Scheme_hash_table::set()
1005 * Plug memory leak in Score_element::molecule_extent ()
1007 * Bugfix: don't crash if a slur doesn't span anything.
1009 * Bugfix: don't crash if doing beams without a staff symbol.
1011 * Generic element property setting:
1013 \outputproperty #predicate #'symbol = #value
1015 Will set the element property symbol to value, for any elements that
1016 return true for PREDICATE. This allows you to virtually tweak *ANY*
1017 property of the output. Example in input/test/generic-output-property.ly
1022 * lilypond as as2ly: --help and --version to stdout. Regular identify
1023 to stderr. This fixes help2man's manpage generation.
1025 * configure: substitute full path for perl and guile in scripts.
1027 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
1029 * Bugfix: default font now user settable
1031 * as2text: handle plain ascii font, read from stdin, you can now do:
1033 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
1038 * Bugfix: second half of broken ties now are displayed again.
1040 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
1041 it horizontally on the clef.
1043 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
1045 * Bugfix: unbroken repeat barlines now work, eg. |:
1047 * Added Request_iterator to make more flexible constructions possible.
1051 * as2text: catch missing font/character errors, added default font, set text.
1053 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
1055 * Ascii output, minimal support:
1056 - AsciiScript Fonts: mf/*.af
1057 - Init files: ly/*-as.*ly
1058 - AsciiScript translation to text: scripts/as2text.scm
1059 - input/test/as.fly input/test/as1.fly
1060 - Output support: lily/lily.scm
1062 lilypond -f as -i init-as.fly input/test/as.fly
1068 * The horizontal part of ties will avoid collision with staff lines.
1070 * Plugged memory leak: don't protect Atom function.
1072 * Lookup cleanups. Made lots of functions static. Moved some code out
1080 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
1081 does not delete any of the file_ly*.tex.
1083 * Added header and footer support in ly2dvi.py
1088 * Added a ROADMAP file explaining the source directory layout.
1090 * Minor tweak in the feta 6 and 9 numeral
1092 * Moved files from lib/ to flower/
1094 * Removed Note_head_side class.
1096 * Updated the webpage to be a little more chatty.
1098 * Small Local_key_engraver optimization: only lookup timing engraver once.
1100 * Fixed dashed slurs
1102 * Rewrite of Slur code. Be much more picky about slur shapes. We try
1103 to offset the slur instead of bending it too much
1105 * Look at stem directions for tie direction.
1107 * Compound multimeasure rests. Put measures_i_ variable in an element
1108 property. Made the symbol a lot wider.
1110 * Time signature small cleanups.
1115 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
1118 * Breathing marks now have a direction by default.
1120 * Do set generic script properties.
1122 * Also put tuplet brackets under notes.
1124 * Score_element_info: only store origin of element, but not the path
1125 to parent translators. Saves a little memory, and removes some complexity.
1131 * Autobeaming in time sigs that don't have 1/4 beats fixed.
1133 * (De)crescendi should now work. (Thanks Michael)
1135 * Better error reporting for conflicting time signatures.
1137 * Line_number_engraver: output locations of note head
1138 definitions. Very handy when entering complicated scores.
1140 * Rewrote multi measure rest support: now they are entered as spanners
1141 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
1143 { \commandspanrequest \start "rest"
1145 \commandspanrequest \stop "rest"
1148 * Removed support of percent style repetitions.
1150 * Put texts outside the staff.
1154 * Getopt bugfix: don't assert on certain errors.
1156 * ly2dvi: Remove unnecessary space for the page headers.
1158 * Bugfix convert-mudela
1163 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
1166 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
1167 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
1168 \property tupletInvisible will stop all tuplet spanner creation.
1170 * Don't go berserk if tuplet spanner is on only one column.
1172 * Use SCMs & Smobs for Molecules & atoms. This uses less
1173 scm_(un)protect_object () calls, so the output stage should be faster.
1175 * Added \property tupletSpannerDuration, to make multiple tuplet signs
1178 * Some programming Errors in spacing are now caught. Lily does not
1179 hang when encountering degenerate springs.
1181 * Allow beams to start and end over rests
1185 * Fix disappearing clefs when clefs are not printed with a barline.
1190 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
1191 input/test/beam-control.fly
1192 * Added \context Voice to .fly and .sly; the default \context Staff is almost
1193 never what you expect
1194 * Fixed decision for .sly/.fly in lilypond-mode.
1199 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
1200 Cleanup mf-to-table.py
1202 * Fixed embarassing slur bug.
1207 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
1212 * lilypond-mode.el for emacs supersedes mudela-mode.el
1214 * Tuplet spanners don't collide with encompassing notes.
1216 * Gobbled Adobe parseAFM* code, for future use.
1218 * Big 1999 to 2000 search/replace.
1220 * Big interline to staff_space search/replace for mf files.
1222 * Removed Bow class, and split code into Tie and Slur
1224 * Don't put scripts on grace notes.
1226 * Font_metric uses SCM for name field.
1228 * Various compilation fixes.
1233 * Bugfix: beams with less than one (visible) stem
1235 * small fixes to pa.ly
1240 * Fixed bug that made multi-measure rest barnumber counts go wild.
1241 (even more scm2int/int2scm mixups!)
1243 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
1245 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
1250 * Remove Paper_def calls in bezier-bow.cc
1252 * Remove data members of Tuplet_spanner, Volta_spanner
1254 * hang_on_clef, property hangOnClef removed
1256 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
1257 function to determine breaking behavior.
1259 * More Scheme typechecking.
1261 * Be strict about the difference between strings and symbols for conversion.
1263 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
1266 * Partial French translation, courtesy Laurent Martelli.
1268 * Small corrections in NL translation.
1273 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
1274 we have a longa note head. noteHeadStyle = "harmonic" is not
1275 supported anymore. (for now, that is)
1277 * Reference manual update. Document \properties with examples
1279 * fix mudela-book --help
1281 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
1282 Key_item::c0_position_
1284 * Clef_engraver general cleanup. Use alists (\property
1285 supportedClefTypes, clefPitches) for clef types.
1287 * Use progress_indication () for progress. Don't include <iostream.h> directly
1288 Don't include <string.h>, <math.h> from headers.
1294 * \property stemCentered (boolean): centers stem on note head. See
1295 input/test/stem-centered.ly
1297 * input/trip.ly, small test of lots of features.
1299 * \property Staff.collisionMergeDotted: merge equal noteheads
1300 with different dot count. See input/test/collision-merge-dotted.fly
1302 * Dotted rest bugfix
1304 * Don't crash if a slur does not span any notes.
1306 * Volta repeats fixed.
1308 * cleanup of Note_heads_engraver
1310 * removed dots_i_ member of Dots
1314 * Fixed cross staff slurs. It seems that cross-staff sign
1320 * Fixed bug in stem code. Stem in chords works again. Small
1323 * Use element properties for Staff_symbol.
1325 * \property sparseTies (boolean). Only make one tie in the
1326 middle for tied chords.
1328 * Junked Directional_spanner, Column_info.
1329 Directional_element now is element interface `Directional_element_interface'
1331 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
