80 * Move Context_specced_music::translator_{type,id}_str_ into music
83 * Don't make line breaks during note playing.
85 * Clef engraver rewrite. Clef-engraver is now controlled through
86 properties clefPosition, clefGlyph, clefOctavation. The \clef command
87 is just a front-end to these, see scm/lily.scm, function
88 clef-name-to-properties. See also input/test/manual-clef.ly

410 (Y-offset-callbacks . (callback1 callback2 .. .))
411 (X-extent-callback . callback1)
412 (Y-extent-callback . callback1)

478 * rest collision of differing rests.
480 * Cleanup of Sequential_music_iterator, Simple_music_iterator.
482 * Unfolded_repeat_iterator now signals repeats using \property
483 repeatCommands. You could override this, eg.
485 \property Score.repeatCommands = #'((volta "X") start-repeat)
487 will print a |: and a volta bracket saying X. See also
488 input/test/manual-volta.ly
490 * Volta_engraver, Repeat_acknowledge_engraver: new engravers that are
491 controlled by repeatCommands; much cleaner than the Repeat_engraver.
493 * Junked Repeat_engraver.

510 number for self-alignment-{X,Y}.
512 * etf2ly: single line GF field.
517 * Added an interscorelinefill paper variable. Set to a positive number
518 in order to stretch the inter-line spacing to fill the full pages,
519 except for the last page (where it would look really ugly).
524 * Changed lilypond to LilyPond in ly2dvi, Mudela to LilyPond source.

531 * Made some fixes to Coriolan.
536 * Only open files, not directories
538 * bugfix: textNonEmpty.
540 * Look ahead in auto-change iterator for rests. This means rests
541 before the note leading to an automatic staff switch are switched as
542 well (improves the looks of scarlatti-test). Associated fixes and
543 additions for Music_iterator::skip () and friends.
545 * Bugfix: only quantise staccato inside the staff.
547 * cleanups for beam and stem. Removed global GUILE namespace calls

555 * Fixed some stupid core dumps processing Coriolan.
557 * Fixed several problems with part-combiner's part-switching.
559 * Fixes for ASCII output.
561 * Added feature to part combiner that should allow part-switching only
562 for entire measures. Currently, it is controlled by a new
563 property changeMoments (A . B):
564 - only switch when !(A mod now),
565 - decide whether to switch based on music during time period B.
567 * Made bugfix: Sequential_iterator::get_music (M): mustn't return music
570 * Added skip (M) to some iterators.
572 * maintain minimum-length by shifting for hyphens at start of
573 line. (patch courtesy Christophe Rhodes)
575 * mudela-book fixes (courtesy Tom Cato Amundsen): documentation
576 update, LaTeX example, landscape support.
581 * Added elt properties for Tie:
584 - staffline-clearance
586 * Added elt properties for Slur
590 * Removed C++ support for barNumberScriptPadding, now in
591 generic-property.scm (but they're deprecated anyway)
593 * Changed threshold in Align_interface to be in staffspace
595 * changed minVerticalAlign and maxVerticalAlign to be in staffspace.
596 A better way: do \push #'threshold = #(cons A B ). (WARNING:
599 * moved translator definitions out of \paper { }, only instantiate in
605 * Sequential_iterator::get_music (), part combiner now works.
607 * Changed paper variables into elt properties:
609 - beam-space-function, Removed Paper_def::interbeam_f(), Smaller
610 beams for grace notes.
611 - beam-flag-width-function to Beam.
614 - horizontal-space: spacing of grace notes is configurable
632 - note-width to Collision
634 * removed various obsolete variables from params.ly
636 * added input/test/bagpipe.ly
641 * Made fixes to part-combine examples and Coriolan.
643 * Bugfix: don't dump core on unterminated (de)crescendo.
645 * Rolled next (M) also into get_music (M), similar to process (M), so that
646 sequential-music-iterator::get_music (M) returns something useful.
648 * Bugfix: part-combiner still expected Music_sequence, where get_music ()
649 now returns plain list of events.
654 * Fixed problem with disappearing crescendi across line break.
656 * Bugfix: dynamic texts should not be set by text-engraver.
658 * Rewrote and cleaned up music-iterator.
660 * etf2ly robustness fixes.
665 * Added side-position-interface as an interface identifier, in stead
666 of checking side-support-elements. This fixes a problem with stacked
669 * Removed spurious set_elt_property ("XX", SCM_EOL) calls.
671 * Added \property squashedPosition for Pitch_squash_engraver: the
672 staff-position number to squash noteheads to.
674 * Added FAQ entry for script on bar, updated description of mailing
677 * Fixed bug with \translator { basicXXXProperties \push ... }
679 * Updated and revised call for help in hacking.texi.
681 * Bugfix: don't remember accidental if it is tied from the previous note.
686 * Separated definition and implementation of contexts (moved
687 definition out of Translator_group into Translator_def)
689 * pmx2ly.py fixes: now handles text at beginning of block correctly.
691 * update .spec to include scripts.
693 * Changed syntax of \pushproperty:
695 \property Voice.basicXXXProperties \push #'foo = #bar
696 \property basicXXXProperties \pop #'foo
699 basicXXXProperties \push #'foo = #bar
700 basicXXXProperties \pop #'foo
706 * Updated INSTALL.texi
710 * Added Documentation/user/mb-latex.tex, mudela-book+latex example
711 file and test case. Some work on Documentation/user/mudela-book.tely
713 * mudela-book.py: any combination of \verb, \begin{verbatim}
714 @code and @example and mudela should work as expected.
716 * dropped [].extend that depend on python 1.5.2
721 * pmx2ly, PMX to LilyPond conversion. Succesfully converts barsant.pmx.
723 * musedata2ly, a Musedata to LilyPond convertor. Succesfully converts
726 * bugfixes for dynamics: make sure that dynamic alignments encompass
727 the dynamics they support, and that any columns they attach to aren't
730 * bugfix: make sure \time gets noticed early enough.
737 * Cleanups related to barline handling:
739 - Removed Translator_group::get_simple_translator (), and -
741 - use properties to communicate about barlines and time sigs. (NOTE:
742 by default a time-signature of 4/4 is printed.)
744 - fix repeat bar behavior.
747 * cleaned up Directional_element_interface
749 * add name field to score-elements.
751 * comment in some unprotects for Music in parser. Should bring down
752 cpu time and plug some leaks.
754 * robustness fixes for etf2ly, tuplets, grace notes.
759 * engraver.ly: cleanups.
761 * etf2ly: robustness fixes, handle mac files as well.
763 * Smobified Translator and Translator_group, junked
764 Translator_group_identifier.
766 * \pushproperty and \popproperty withing \translator, similar to
767 predefining \property, ie.
769 \translator { [...] \pushproperty [..] }
770 \translator { [...] \popproperty [..] }
772 (these \pushes and \pops are delayed until instantiation, so if you do
776 \pushproperty #'basicFooProperties #'bla #VALUE1
777 \context Voice { \pushproperty #'basicFooProperties #'bar #VALUE2
782 then the setting for basicFooProperties contains both (bla . VALUE1)
785 * allow \pushproperty #'symbol [..] as well as \pushproperty #'(symbol1 symbol2 ... )
790 * Activated regex for windows.
792 * New guile-1.4 patch for cross windows build.
794 * Added configure messages for metapost checking.
801 * Added property LyricVoice.associatedVoice to enable switching associated
802 voice mid-stream. Association still defaults to context name.
807 * \pushproperty, \popproperty: property settings with less memory
808 cost. See input/test/pushproperty.ly and Documentation/hacking. Note:
809 syntax is most likely only temporary.
814 * (Line-)broken slurs now have vertical trend.
816 * Better length for broken ties: no invisibly short ties. Now ties may
817 collide with time signatures, though.
819 * Don't typeset unfinished spanners, but kill them.
821 * Added two FAQs (Mats)
823 * Made workaround guile-1.4.1 backward incompatible (scm_)eval change.
824 Note that we must use (scm_)eval2 to remain backwards compatible with
825 guile < 1.4.1 snapshot.
827 * Reincluded 79.jcn2 fix
835 * Created Thread_devnull_engraver and Voice_devnull_engraver iso
836 single A2_devnull_engraver in Thread context. It seems however
837 that the hack in A2_devnull_engraver works better.
841 * Slur attachment fix for chords where case slurdir != stemdir.
843 * Made various fixes for (line-)broken slurs.
845 * Fixed slur_height (), which fixes most ugly slurs (Yeah!).
847 * Fixed some silly url reversals in FAQ.
849 * Finished Coriolan music entry (again); entered second viola part.
851 * Updated Coriolan to use part combiner on Voice level for wind parts
852 and on Staff level for violi and bassi.
854 * Part-combiner now uses duration inquiry, which fixes rhythm-related
855 bugs in determining solo/a2. Also, rests are taken into account.
857 * Another crude fix for almost unexplainable (with a gdb that dumps
858 core on ly_display_scm) all-zero control points slurs.
860 * Fixed slurs that crossed through stems and note heads. Note
861 that beautifying of ugly slurs is still broken.
863 * Made crude fixes slurs don't crash, bezier still crashes on
864 infinitely steep slurs (eg flauti-part *with* slur_engraver).
869 * Replaced empty melisma score element with a property
871 * Renamed Voice_alist_entry -> Syllable_group in lyric-phrasing-engraver
876 * fixed y-position of whole rest
878 * fixed sustainPedalPadding
880 * etf2ly: articulation, lyrics.
885 * etf2ly.py: Finale to LilyPond conversion.
890 * Made simple fix to get part-combiner to recognise different rhythms
892 * Unhardcoded part combiner and a2-engraver; introduced properties
893 splitInterval, soloADue, soloText, soloIIText, aDueText.
895 * Fixed part combiner's too-late problem (Dankje!)
897 * Fixed a2-devnull-engraver, a2-engraver.
899 * Renamed part combiner music names to "one", "two".
901 * Cleaned up decision making in part combiner, renamed to "solo"/"unison"
906 * Minor documentation updates
908 * Mark_engraver: has been broken since .73, fixed!
913 * Added a devnull engraver, that junks (notehead) requests of the second
914 stem when combined parts are in unison (a2).
916 * Part-combine iterator identifies Soli and A2 parts in threads by
917 looking at rhythm and pitches. It switches Voice context automagically,
918 and communicates current state using a2/solo/solo2 properties.
920 * Simple A2_engraver (`a due) prints `a2/Solo/Solo II. Soli seem to
921 arrive one request late.
923 * First try at combining parts: part-combine*
925 * fixed problem with HaraKiri
927 * fixed problem with dynamicDirection
929 * fixed problem with nonEmptyText
931 * `Fixed' chord notation, as per request of David Arnold, ie,
932 Added a chord-name-mode, that only displays chord names
933 when there's a change in the chord-name-scheme, Also, a chord
934 name should always be displayed after a line break. See
936 input/test/drarn-chords.ly
938 * Reverted duration-iter change in midi2ly, moved printing of options.
940 * warning bugfix in lexer.ll (Mats Bengtsson)
945 * Midi2ly bugfix: handle durations longer than longa. These can occur
946 because of lengthened notes when using --no-rests.
948 * Midi2ly: output `new' \key syntax, and updated version number.
950 * Midi2ly bugfix: don't correct quantised durations, don't use tuplets,
951 double dots etc. when user doesn't want them. It probably used to
952 work like this, a long time ago. For some unknown reason, all
953 corrections made by Duration_convert were junked if the corrected
954 duration != exact duration. Duh.
956 * Midi2ly: added a new option: --no-rests.
958 * Update of mudela-book (Tom Cato Amundsen)
959 - --read-lys option, now you can do:
960 mudela-book file.texi
962 mudela-book --read-lys
963 - --outdir=DIR will put ALL output into DIR
964 - @mudela[filename="myfilename"]{c d e f g}
965 - --force-mudela-fontsize
966 - ignore mudela inside @ignore @end ignore
971 * Lyric_phrasing_engraver now catches lyric extenders and correctly
972 terminates them under the last note of a melisma.
974 * Lyric word spacing code changed to fix hyphen alignment.
976 * Other minor tidying up of Lyric_phrasing_engraver and related code.
981 * Lyric_phrasing_engraver now adjusts for melisma. (Glen Prideaux).

985 * Debian update (Anthony Fok)
987 * Added beam melisma for when automaticMelismata and noAutoBeaming are both
988 #t (primarily for hymns). Courtesy Glen Prideaux.
990 * Bugfix: .pfa dependency on $(outdir)/mfplain.mem
995 * stepmake/stepmake/metapost-rules.make: Put all generated files
998 * Added paper variable interscoreline to determine the score line
999 spacing, see input/test/vertical-extent.ly.
1000 Cleaned up the lilyponddefs.tex inclusion scheme.
1008 * Improved default handling of Lyric_phrasing_engraver and made it on by
1011 * Beginnings of a stanza number engraver (\property LyricVoice.stanza =
1014 * fixed bug in script.cc so fermata (and other scripts) get flipped
1015 correctly when they are above the staff.
1020 * Reincluded simple code for including tfm.[1-5] into search path.
1021 Configure with --disable-kpathsea to enable this kludge.
1026 * Updated input/test/banter-chords.ly German H/B example.
1030 * Have configure check for kpathsea library and functions. Made kpathsea
1031 support optional for now.
1033 * Bugfix: halved width of tremolo-beams.
1035 * Included compilation fix for guile-1.3.4 (Anthony).
1037 * Added: chord inversion and base to regtest.

1055 * Cleanup, documentation and enforcement of smob interfaces in
1056 LilyPond. We distinguish between SIMPLE_SMOBS and SMOBS (objects that
1059 * Glen Prideaux lyric phrasing engraver. See
1060 input/test/lyric-phrasing.ly
1064 * Removed \interscoreline after the last line, prevents some
1065 empty pages. (patch by Mats Bengtsson)
1067 * Smobified Music, junked associated identifiers. Use Scheme list to
1068 store Music_sequence. Removed const declarations from
1069 Music_iterators. Added a mutable and immutable property list to
1070 Music. Use music property for all Scheme values in Music. Created
1071 and fixed a load of Garbage Collection bugs.
1073 * Changed number font to allow automatic .mf creation.
1075 * Output place of definition as \special{src:LOCATION}. See FAQ for
1076 explanation how to use.
1078 * Schemified Local_key_item and fixed minor bug with accidentals.
1080 * new Japanese .po file.
1082 * Bugfix for broken tie direction
1084 * Bugfix for bar at beginning of line break

1091 * cleanups of Slur_bezier_bow, removed Bezier_bow.
1093 * cleanup of Tie. Changed Tie into interface. Made ties flatter by default.
1095 * changed SCM_UNDEFINED to SCM_UNSPECIFIED for return values that go
1098 * changed SCM_UNSPECIFIED to SCM_EOL for undefined element
1099 properties. This makes initializing list properties redundant.
1101 * removed idiotic code for including tfm.[1-5] into search path.
1103 * fixed problem with tuplet placement for cross staff tuplets.
1107 * Small cleanups to bring down compile time and binary ensmallment.
1109 * Made Lookup into a smob, and use guile alist iso. an STL map.
1111 * Changed repeated music semantics for relative octave: each
1112 alternative takes its inital octave from the body.
1114 * Fixed: parser accepts booleans for property values as well.
1116 * Added Scarlatti sonata test file to input/
1118 * kpathsea support, courtesy Carsten Block <carsten.block@gmx.de>
1122 * Fixed: long standing problem in optical-illusion code.
1124 * Fixed: stop beam if stem *has* a beam in auto-beam-engraver.
1126 * Made interface of Multi_measure_rest, System_start_delimiter,
1127 Spacing_spanner, Separating_group_spanner, Beam, Slur and
1130 * Use properties for minimum distances and spring parameters. Move
1131 spacing related functions from Paper_column into Spaceable_element.
1133 * Removed most Paper_column typecasts.
1138 * Cleanup auto-beam-engraver: use properties for retrieving timing
1141 * Fixed: Multi measure rests don't cause crashes.
1143 * Fixed: don't invoke Hara_kiri::consider_suicide too early.
1145 * Fixed: property engraver.
1147 * Fixed: don't crash on multiple ties.
1149 * Cleanups of Beam, should also be a little faster.
1151 * Reunite properties and pointers. In implementation we make a
1152 distinction between mutable and immutable properties

1157 statics class, and stripped _interface suffix.
1159 * Make Align_interface and Axis_group_interface an all-statics class
1161 * Rhythmic_head, Staff_symbol, Grace_align_item, Break_align_item,
1162 Bar, Span_bar are now interfaces, Staff_bar was removed. Use a
1163 callback for determining barsize.
1165 * Removed all GLUE_SCORE_ELEMENT callbacks.
1167 * Added test for repeats to trip.ly
1172 * ly2dvi: changed back to original semantics of latexheaders.
1174 * Stem_tremolo, Crescendo, Hara_kiri_group_spanner, Tuplet_spanner,
1175 Volta_spanner changed into interface.
1177 * Related cleanups for Tie, Tie_column cleanups.
1179 * Made Time_signature, Single_malt_grouping_item, Script_column,

1182 * Removed const declaration from callback arguments.
1184 * Pagebreak support. See input/test/between-systems.ly
1186 * Fixed a problem with accidentals in combination with
1187 non-nil key signatures.
1192 * Use callbacks for augmentation dot positioning.
1194 * Removed types Note_head and Rest
1196 * Cleanup of slur.cc: use common reference points in a sane manner.
1201 * Corrected text sizes in paper*.ly (Mats Bengtsson)
1206 * Dots, Collision, Rest_collision removed as separate Score_element type.
1208 * Stem and Note_column accept only one rest.
1210 * Use offset callback in Stem to resolve rest/beam collisions.
1212 * Put the value of new local key signature (accidentals) back into a property.
1214 * Set molecule-callback for notename item.
1219 * Added some comments to new slur code.
1221 * Removed some ugly interstaff slur code, interstaff slurs at line-break
1224 * Slur bugfix: 16th beams are also beams.
1230 * Bugfix: translate volta spanner at start of line.
1232 * Changed directional_element() calls to instantiations
1233 of Directional_element_interface.
1235 * Removed Dynamic_line_spanner, and cleaned up Dynamic_engraver.
1237 * Removed Staff_info type. Information about columns is now transferred
1238 via currentMusicalColumn and currentCommandColumn.
1244 * Made slur attachment position user settable; properties:
1245 slurBeginAttachment slurEndAttachment, values: 'head 'stem
1246 'along-side-stem. See input/test/slur-attachment.ly and ophee-slurs.ly.
1248 * Fixed slur attachment positions, added missing rule and use simple
1249 default starting positions for attachments.
1251 * Started rewrite of slur ending code, interstaff slurs are broken for
1254 * Fixed download URL of the webpage.
1256 * Moved direction.cc to flower/.
1261 * Lyrics centered on notehead.
1263 * Various bugfixes hyphen-spanner.
1265 * Bugfix: set appropriate callbacks for Note_head. This fixes
1268 * Removed Clef_item as score-element derived type.
1270 * Updated config.sub and config.guess
1272 * Bugfix: allow linebreaks on beamed grace notes.
1277 * Included dutch po-update based on submitted 1.3.57 nl.po
1279 * Added "Development" link to website, now that "Home" is a relative link.
1281 * Bugfix: use deep copies for resetting keys.
1283 * Assorted typing erors in procedure names in ly/engraver.ly
1288 * Made callbacks from Score_element::before_line_breaking() and
1289 Score_element::after_line_breaking()
1291 * Fixed website; backlinks should work again.
1293 * Removed --ignore-version option. Added --verbose option.
1303 * Junk int_identifier, real_identifier. Merged Midi_def_identifier and

1306 * Fixed bug with spanning barlines in combination with Hara-Kiri staffs.
1308 * Cleaned up Text_item, Hyphen_spanner, Lyric_extender and
1309 Sustain_pedal and reduced them to an Score_element interface (they are
1310 no longer Score_element derived types).
1312 * Some instances of brew_molecule routines have moved out of
1313 Score_element, and are now called scheme_molecule.
1315 * Moved lots of parameters from ly/params.ly to ly/engraver.ly
1320 * Removed String_identifier, and use the type system of GUILE instead.
1322 * Fixed \key PITCH MODALITY syntax. The modality argument is now
1323 mandatory, a rule in convert-mudela has been added.
1325 * Cleaned up buildscripts/ directory: removed obsolete scripts.
1327 * Use Scheme_hash_table for identifier Scopes. Scheme_hash_table is
1328 based on STL and should be faster than hash_table.
1334 * Fixed scm_un/protect_object for guile-1.3.4 and 1.3.5 snapshots,
1335 in the process reduced number of protect/unprotect calls. With
1336 guile-1.3.5 snapshot, memory usage has decreased by 1/5th, now
1337 just 10% above the 1.2 level. Also, Lily's a bit faster.
1339 * Fixed make diff bug in stepmake to be able to make this diff :-)
1344 * Rewrote key sig support. Now key signature can also be controlled
1345 by setting keySignature and localKeySignature properties, eg.
1347 \property keySignature = #'((2 . -1) ( 4 . -1) (6 . -1))
1349 sets a key signature of `es ges bes' (an unusual key signature).
1351 Keys are internally represented as transpositions of the c-major
1352 scale. Printing the key signature for a scale is done by filtering out
1353 all non-natural accidentals.
1355 * Removed support for \keysignature, and \key something \minor; Newkey
1361 * Fixed pedal items (hw)
1363 * Changed configure option tex-tmfdir to tmf-path now accepting multiple
1364 tfm directories. Automated links to cmr and amstex tfm font directories.
1366 * Replaced one scm_assoc () u-turn slipped through jcn1
1368 * various GUILE 1.3.5 compile fixes

1374 * Ran po-update (mostly because of new ja contribution).
1379 * Cleaned-up scheme list to text conversion for Chord_name and
1380 fixed horizontal kerning.
1382 * Added examples for american (slashed o) and jazz (black triangle),
1383 see input/test/{american-chords.ly,jazz-chords.ly}
1385 * Made guile-1.3.5 compile fixes
1390 * Fixed typo in Dots::do_brew_molecule (); this fixes the disappearing
1393 * Rewrote key signature administration; now Scheme is used; Octave and
1394 Key have been junked in favor of Newkey.
1396 * japanese .po file included (thanks, Japanese team!)
1401 * Fixed several forgotten molecule-callbacks
1403 * Fixed first clef in score; now F clefs are also possible.
1408 * Updated FAQ with two useful GDB macros.
1410 * Several fixes in the documentation.
1415 * Made (dutch) po-update
1420 * Molecules are now generated via callbacks exclusively; most calls to
1421 set_elt_property ("transparent", SCM_BOOL_T) have been replaced by suicide().
1426 * Experimental property collapse for most score-elements. (notable
1427 exceptions: Scripts, pedals). Change all Score_element constructors to
1428 take a basic-property list. The suffix of a property list may be
1429 shared by several score-elements, for instance all default G-clefs in
1430 a score share the following settings
1433 (break-align-symbol . Clef_item)
1434 (visibility-lambda . ,begin-of-line-visible)
1436 This should reduce memory usage further.
1438 * Magically fixed the disappearing Lyrics problem.
1440 * Removed used_b_ field from Score_element.
1442 * Massive search-replace patch: store pointers and properties
1443 separately, in preparation of property collapse.
1449 * Bugfix: don't crash on tuplet spanners that don't contain any notes.
1451 * Cleanup of Dimension_cache: removed a few redundant
1452 fields. Slightly lower memory usage (32 bytes per
1453 score-element). Dimension_cache is now a `dumb' struct again.
1455 * Add array index to priority field of text scripts to ensure that
1456 order is unique, and sensible.
1458 * Added an element count statistic.
1463 * russian.po (thank you, August.)
1465 * Small cleanups in Molecule interface
1467 * Spacing related elements perform suicide after calculating
1468 distances. This saves a some memory, approximately 2 to 5 % ?
1470 * Small cleanups in line breaking: Paper_column stores springs and
1471 rods in only one place now. All fields relating to energy have been
1474 * Don't generate all output Scheme in memory, but evaluate to output
1475 file immediately. This will reduce memory usage a little.
1477 * Use STL's map for Dictionary template
1479 * Substitute pointers on element properties of the root Line_of_score
1482 * Added toplevel doc target, to support building doc with --srcdir
1484 * Removed cygwin build stuff; updated versions at:
1486 http://appel.dyndns.org/lilypond/gnu-windows/cross
1488 * Fixed lily.scm to handle incipits (thanks, Mats)
1494 * Made bugfix in smob handling: delete the C-part of freed smobs and
1495 be honest about amount of allocation and deletion, so that GUILE
1496 doesn't overestimate the amount of memory available.
1498 * Faq update: nicer blank note paper, courtesy Mats Bengtsson.
1500 * Bugfix: don't crash on durations that are not a power of 2.
1502 * Build manpages during `make all'
1504 * Bugfix: don't do absolute comparisons in Polynomial::clean ().
1506 * Bugfix: set visibility-lambda for key signature created by
1507 createKeyOnClefChange. Fixes disappearing key signatures.
1509 * Bugfix: make System_start_delimiter of bar-line type invisible when
1510 it spans only one staff.
1515 * Item cleanups. Copying items and rearranging pointers are done in
1516 separate passes, which makes the code cleaner. This fixes a problem
1517 with some items not disappearing from hara-kiri staffs.
1519 * Use Scheme for Key_item data members.
1521 * Don't use regex in chord-names.scm under windows; hybrid chordnames
1522 user+calculated will be partly broken.
1527 * Junked Shift_tuple from collision; Now it uses SCM.
1529 * Bugfix of documentation and test-file of tuplet.
1531 * Bugfix type string of repeated music is copied. This fixes declared
1534 * Junked various cruft from lily.scm
1536 * Use interfaces symbols instead of C++ class-name for assigning generic
1539 * Junked Dictionary from Piano_pedal_engraver and
1540 Piano_pedal_performer.
1542 * Introduced boolean element property no-spacing-rods: ignore this
1543 item for hard constraints.
1545 * Bugfix: added sanitised TeX fragment in faq.texi
1547 * Bugfix: merge equal Bar_reqs
1552 * Small fixes for \cresc and \endcresc
1554 * Release properties of unbroken spanners & items after doing
1555 handle_broken_smobs (); should conserve a little memory.
1557 * Fixed handling of orphaned score-elements. Any element that does
1558 not have its Line_of_score as a ancestor in both directions, is silently
1559 removed from the output. This guarantees that programming errors
1560 don't result in coredumps from Dimension_cache::common_refpoint ():
1561 element->line_l () is always a common reference point.
1563 * Bugfix: set visibility-lambda of clef and octavation-8 explicitly
1564 for default case. Now the octavation 8 is not printed at every
1570 * Changed noteHeadStyle properties to symbols, for example
1571 \property Voice.noteHeadStyle = #'cross
1576 * Rewrite of chord-name production in scheme. There are two major styles
1577 now, banter and american. To get american style, use
1579 \property ChordNames.chordNameStyle = "american"
1581 Most anything should be possible now. See input/test/american-chords.ly
1583 * Added isinf check to configure.in, and isinf macro from guile to
1584 bezier.cc; solaris has no isinf ().
1586 * Fixed star-spangled-banner with not-so-nice \bar "|." fix. Almost
1589 * Added output property to regression test.
1591 * Fixed warning of creating existing outdir.
1593 * Added `Mark' interface to text-items that are marks (thanks, HW).
1600 * Corrected glossary.tely
1602 * Corrected \mark font handling. feta-nummer font only of the
1603 string is all numeric.
1605 * Implemented noteHeadStyle lookup in Guile. Reintroduced the style
1606 "harmonic" and added "baroque" (normal note shapes except for
1607 brevis and longa which are square).
1609 * Simplified ly2dvi using the power of the geometry package.
1611 * Improved heuristic size calculation of TeX macros. Handles e.g.
1612 "\\u{a}", "\\"{o}" and "\\^{u}" correctly.
1617 * Bugfix: don't hang on zero-duration.
1619 * Various glossary updates (thanks, Christian)
1627 * Drastically reduced vertical space used by headers/footers, when using
1628 ly2dvi. See input/test/fill-a4.ly.
1630 * Fixed bug with colons appearing on repeat span-bars.
1632 * Added Bar_number_engraver to standard Score context
1634 * Construct octavation scripts in the clef-engraver; this fixes the
1635 hara-kiri + clef8 problem
1643 * Fixed chord-name customisation and made small chord-name build fixes.
1645 * Accidentals with chord-names smaller and as superscript.
1647 * Do some extra footify (works only once) while making html docs.
1652 * Debian patch (Thanks Anthony)
1654 * Rewrote Bar_number_engraver and Mark_engraver and removed
1655 Bar_script_engraver as baseclass. Both Bar_number_engraver and
1656 Mark_engraver are simpler and more robust.
1658 * Fixed precedence of \property verticalDirection and dynamicDirection
1660 * Fixed keys without barlines
1662 * Fixed StaffGroups: removing `\consistsend "Axis_group_engraver"'
1663 puts alignment in function again
1665 * Fixed StaffGroup + GrandStaff combination.
1667 * Music is now mandatory as the first thing in a \score{} block
1674 * Implemented una-chorda and sostenuto piano pedals in performer and engraver.
1676 * Added Properties textScriptWordSpace and chordNameWordSpace.
1678 * Junked old lyrics in star-spangled-banner.
1680 * Added a Piano_pedal_engraver.
1682 * Removed some empty files.
1684 * Created piano pedal symbols: * - . P e d.
1686 * Fixed ps-to-pfa.py to handle multiple unfills.
1688 * Moved accordion symbols out of feta-script to end of font.
1690 * Bugfix: don't create tfm's, pfa's etc of feta-test fonts.
1692 * Fixed blot_diameter for small resolutions.
1697 * Put global element list into Line_of_score, instead of
1698 Paper_score. post processing (the stage after line breaking) is now
1699 truly done per-system, and we got rid of an ugly hack to get font
1702 * Bugfix: set the group-interface of System_start_delimiter.
1704 * Cleanups of Break_algorithm and derived classes, Move
1705 broken_col_range () to Line_of_score, remove Paper_score::col_l_arr_
1707 * Bugfix for accordion symbols.
1709 * Various patches to prevent crashing when do_brew_molecule gets
1710 called before after_line_breaking (). This was a problem in Spanner
1719 * Made a quick try at piano pedal performer, damper pedal only.
1721 * mf/feta-accordion.mf: Fixed strange turning paths.
1723 * mf/feta-beugel.mf: Fixed infinity errors.
1725 * Use a more discriptive name for windows setup.zip.
1727 * mf/GNUmakefile: Have logs as last target, so that normally, they're
1730 * stepmake/stepmake/metafont-rules.make: Don't remove the .log files.
1731 The logs are a target, removing them retriggers make.
1733 * stepmake/stepmake/metapost-rules.make: Remove the correct log and tfm
1734 files, ie the ones that clutter the source directory, not the target logs.
1736 * Windows distribution: faked symlink for cmtfm. Setup.zip should now be
1737 standalone; ie, no need for Cygnus' usertools anymore.
1742 * Documentation/ntweb: Updated angels.ly to match current syntax.
1743 Also updated index.texi.
1748 * Change all occurances of Staff_margin_engraver to
1749 Instrument_name_engraver, add a convert-mudela rule
1751 * Change status == busy assert into programming error
1759 * Lots of fixes to windows distribution scripts.
1761 * Added configuration features --program-prefix, --program suffix.
1763 * lily/my-lily-parser.cc (get_chord): Bugfix, don't use deleted pitch.
1764 This fixes inversions c/g and bass additions d/+c on chords.
1769 * Avoid that xxxXXXVerticalExtent is used for empty HaraKiriStaff
1775 * Debian patches (thanks Anthony!)
1777 * Use symbols for prefatory matter spacing. Do not use the typename
1778 for looking up item pairs in the table, but read element property
1781 * Instrument_name_engraver, uses break alignment instead of
1784 * System_start_delimiter_engraver, System_start_delimiter, uses a
1785 spanner for the braces/brackets at the left of the system. Remove all
1786 old Span_score_bar engravers.
1788 * Removed Base_span_bar_engraver::use_prority_b_, and moved
1789 Base_span_bar_engraver into Span_bar_engraver.
1794 * mutopia/Coriolan/violino-2.ly: Bugfix: wrong pitch.
1796 * input/test: Removed stale AutoStaffSwitch examples.
1798 * mutopia/E.Satie: Fixed gnossiene-4, doing \autochange. Removed
1799 stale copy of gnossiene-4.
1801 * buildscripts/make-cygwin-cross.sh: Made some small .zip package fixes.
1803 * make/lilypond.spec.in: Made some bugfixes for _prefix, preparations
1804 for cross-building to Cygwin.
1806 * buildscripts/make-cygwin-cross.sh: Now using rpm packages.
1811 * added \property XXXMinimumVerticalExtent, \property XXXExtraVerticalExtent
1813 * New_chord_tremolo_engraver: make tremolo beams from
1815 \repeat "tremolo" NUMBER <Music-expression>
1817 Removed support for "old-style" tremolos.
1819 * Add a convert-mudela function for the conversion "\key A;" to "\key a;
1821 * Read \property measurePosition within the engraver code, instead of
1822 looking up the Timing_translator.
1824 * star-spangled-banner.ly: add Bar_engraver to LyricsVoice
1826 * Changed all .fly and .sly files to .ly files. Propose to dump .fly
1835 * buildscripts/mf-to-table.py: feta dep files are now opened with write
1836 binary option. This avoids carriage return linefeed problems and
1837 windows while not affecting unix.
1839 * Documentation/hacking.texi: Fixed a texinfo syntax error
1841 * stepmake/bin/package-zip32.sh: Fixed or Removed some legacy, 1.2.x,
1844 * Documentation/ntweb/index.texi: Fixed broken links, added 1.3.39 links.
1849 * Glossary updates by Christian Mondrup.
1851 * Bugfix: use generic properties in lyrics too. This fixes the
1852 \property textStyle for lyrics.
1854 * Score_element::preset_extent(), used by \property
1855 XXXVerticalExtent, so hard code the size of a vertical group.
1857 * Don't fix up reference points for originals of broken
1858 spanners. Fixes spurious "orphaned score-element" warnings.
1860 * buildscripts/make-cygwin-cross.sh: Use rx-1.5 instead of regex (Jeffrey).
1862 * scm/lily.scm: Fixed check for Windows: by default don't use scm regex.
1864 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: Significantly smaller
1867 * buildscripts/make-cygwin-cross.sh: Compile native package GNU regex,
1868 which should fix Windows problems with guile. Also added input directory
1871 * stepmake/aclocal.m4: Added decent checking for version of guile, and
1872 fixed warning message.
1874 * lily/lexer.ll (My_lily_lexer): Bugfix: lookup chordmodifiers in the
1875 chord-modifier table (not in the pitch list).
1883 * General cleanups of My_lily_parser.
1885 * Start of a Chord_tremolo_iterator for the `\repeat 4 "tremolo"'
1888 * Moved Score_element::do_space_processing out of the dependency
1891 * Use Scheme for notename tables. Removed uppercase letters for low
1892 octave notes. Removed Notename_table.
1894 * Fixed core dump with declared "\key ; "
1896 * Extra robustness warning for Side_position_interface::aligned_on_self ()
1898 * Extra robustness: make sure that first and last columns are breakable.
1903 * stepmake/aclocal.m4: Added support for cross-compiling with guile.
1905 * buildscripts/make-cygwin-cross.sh: A try at dropping cygwin1.dll
1906 dependency by using mingw. Compiling guile is too much to ask
1907 for mingw, though. Also:
1908 - rename python scripts .py (request from Alain)
1909 - install native packages under their own, separate root. (Alain)
1911 * lily.scm: Don't use regex module when running on
1914 * lily/staff-margin-engraver.cc (acknowledge_element): If
1915 possible, hang y-axis of margin script to span-bar. This fixes
1916 vertical placement of margin scripts attached to staff groups.
1918 * help2man-rules.make: Fixes for generating manpages by copying
1919 and for building using --scrdir.
1921 * stepmake/stepmake/generic-targets.make: Preserve date stamp of
1922 config.h, version.hh files file when copying.
1924 * buildscripts/make-cygwin-cross.sh: made number of fixes:
1925 - add `Cygnus/' prefix to directories in .zip-file too.
1926 - package guile too.
1927 - don't link to cygwin1.dll
1929 * stepmake/stepmake/install-targets.make: bugfix, don't fail if directory
1930 is not emty when uninstalling.
1932 * stepmake/stepmake/generic-targets.make: added man target.
1934 * buildscripts/make-cygwin-cross.sh: new script for cross-building cygwin
1935 development tools and lilypond executable.
1937 * Documentation/ntweb/lilypond-manpages.patch: provide pre-built
1938 manpages, so that make doesn't fail on help2man trying to execute
1939 a GNU/windows executable.
1941 * Documentation/ntweb/guile-1.3.4-gnu-windows.patch: new patch for
1944 * flower/libc-extension.cc (memmem): cygwin compile fix.
1952 * (generic-property.scm) added \property tieDash to set dashing on
1955 * Removed ly_eval_str(), we should use scm_eval (Scm_object).
1957 * Removed scm_to_array (), array_to_scm (), associated junk. Reverted
1958 undocumented .29 patch that made Bezier::control_ into an
1959 Array<Offset>. Added some comments documenting the reasons for the
1962 * Revert generic-property.scm of .37 fix, fix the real problem in
1963 property-engraver.cc: use the right symbol to check if element
1964 property is already set.
1969 * Fixed srcdir build, so that you can do:
1971 tar xzf releases/lilypond-x.y.z
1974 ../lilypond-x.y.z/configure
1977 as with any other gnu package. All build output goes to <build>/out.
1979 * Changed and fixed use of different configurations, and different output
1980 directories. Finally, you can use different configurations alongside
1981 eachother. From make/stepmake.make:
1983 # Use alternate configurations alongside eachother:
1985 # ./configure --enable-config=debug
1988 # uses config-debug.make and config-debug.h; output goes to out-debug.
1991 # Use same configuration, but different output directory:
1995 # uses config.make and config.h; output goes to out-www.
1999 * Fixed performance of (de)crescendi.
2001 * Better documentation for arithmetic_multiplier and arithmetic_basicspace
2004 * Added instrument-equaliser for MIDI output, see scm/midi.scm, and
2005 properties midiMinimumVolume, midiMaximumVolume, ranges [0,1].
2007 * Changed absolute midi volume settings into factor of full scale.
2009 * Fixed another dynamic-line-spanner bug, it gets hairy.
2011 * Added warning for spanners that are not fully contained in parent spanner.
2019 * Abstract Align_element into Align_interface. Removed
2020 Axis_align_{item,spanner}, Align_element, Super_element, all multiple
2021 inheritance in the backend.
2023 * new Gade score, INSTALL.texi fixes (thanks, Mats)
2025 * Removed Item::hpos_f (), Score_element::{get,set}_real ()
2027 * comments detailing properties for Axis_group_interface,
2028 Side_position_interface, Score_element, Item and Spanner
2033 * Fixed vertical dimensions of elements in dynamic line spanner by adding
2034 axis-group to dynamic line spanner.
2036 * Bugfix: line-spanner lasts always full duration of (de)crescendi.
2038 * Bugfix: broken (de)crescendi on a dynamic-line-spanner.
2040 * Bugfix: compilation dynamic-engraver.
2042 * Added and updated a faq about postscript and ghostscript.
2044 * Fixed order of slurVerticalDirection verticalDirection in
2045 generic-property.scm. Similar fixes for Stem, Tie, etc.
2047 * Added a Text_engraver to GraceContext. Maybe it was removed on
2048 purpose: scripts on grace notes seem broken, they appear on the
2051 * Bugfix: volume effect of (de)crescendi was sometimes wrong way round.
2058 * textEmptyDimension changed into textNonEmpty, default: off,
2059 ie. texts don't occupy space.
2061 * Use STL map for Lookup::lookup_p_tab_p_
2063 * Abstracted Axis_group_element into Axis_group_interface, and removed
2064 Axis_group_element. This eliminates some multiple inheritance in the
2070 * Added minimum-space property to Side_position_interface. Used in
2071 positioning of Volta_spanner: voltaMinimumSpace.
2073 * Fixed and cleaned-up volta-spanner.
2075 * Moved directional-element.cc -> directional-element-interface.cc
2077 * Renamed all `process_requests' to `process_music', which fixes
2080 * Fixed dimensions (more x-y interchanges) of brace, bracket and
2083 * Half-assed fix to get similar vertical placement of orphaned vs.
2084 line-spanned dynamic elements.
2086 * Added property bracketCollapseHeight: the minimal size of a staff bracket
2087 that will be typeset. Smaller brackets will not be displayed. This
2088 fixes the (in 1.3.x reintroduced) funny duck-beak-bracket-bug (sorry).
2090 * Removed some dissonant chords from Coriolan
2095 * Removed Documentation/programmer directory
2100 * Small enhancements to Staff_margin_engraver:
2101 - by default, the marginScript left aligns the text
2102 - to set the text style, use property marginScriptTextStyle
2103 - to change the alignment, use property marginScriptHorizontalAlignment
2104 (centred and right alignment require manual padding settings).
2106 * Print a friendly message if the manual pages failed to build.
2108 * Bugfix: dynamicDirection now overrides verticalDirection setting.
2110 * Warning messages and nl.po
2112 * Fixed vertical alignment for all dynamic items and (reluctantly)
2113 reinstated old directional behaviour for orphaned dynamics.
2115 * Finished maximumRestCount property.
2122 * Print key without setting key, syntax "\key ;". General cleanups of
2125 * Add paragraph tags in HTML output of mudela-book. Music fragment
2126 don't run into the text anymore.
2128 * Bugfix: don't align the first line of text. (Lookup::text ()).
2130 * Abstract away data members of Axis_group_element, Align_element
2136 * Added helpful properties instrumentScriptPadding/instrScriptPadding for
2137 Staff_margin_engraver.
2139 * Removed some empty files, substituted (c) 1999 occurrences.
2141 * Added \property maximumRestCount. It will prevent showing (or actually:
2142 moving in case of a collision) more than maximumRestCount similar rests.
2145 * Rewrote Staff_margin_engraver. Staff margin texts now hang on a new
2146 breakable item: Left_edge_item.
2148 * Fixed vertical alignment for dynamic elements. Orphaned dynamic items
2149 (not supported by a Dynamic_line_spanner) still collide with Staff,
2150 although they now have staff support, which was supposed to fix this.
2152 * Fixed Staff_margin_engraver for "instrument", "instr" is still broken.
2154 * Dynamic elements are only put in a Dynamic_line_spanner if there
2155 actually is more than one adjacent note-column with a dynamic.
2156 This breaks the fine looks of all dynamics, again :-)
2167 * Experiment: use STL map for Scheme_hash_table; Is there a speedup?
2169 * Bugfix: print brace iso. bracket for Piano / GrandStaff
2171 * Change naming: change do_post_processsing into after_line_breaking,
2172 do_pre_processsing into before_line_breaking and do_process_requests
2173 into do_process_music.
2175 * Bugfix in hash-table.hh: do quadratic probing, and not cubic probing.
2177 * Display property name for type error.
2179 * Cleanups for Dynamic_engraver and Dynamic_line_spanner.
2181 * Warn if last column in score is musical. Helps catch programming errors.
2183 * Spanner::spanned_drul_ now is private.
2185 * Rewrote some bar code: moved molecule functions out of Lookup.
2190 * Embedded newlines in text items are now allowed. This helps avoiding
2191 TeX-hacking in some cases. See input/test/coriolan-margin.ly
2193 * Fixed stupid x-y interchange bug for staff-bracket. This fixes
2194 placement of staff-brackets.
2196 * Fixed bracket/arch-thickness interchange bug, and made bracket a bit
2199 * Fixed slur/bezier-beautiful name mismatch. This should fix the steep
2200 slurs that were apparently reintroduced in 1.3.29.
2202 * Made some small fixes to Coriolan.
2204 * Removed duplicate lily/output-property-engraver.hh.
2206 * Removed optional use of vanilla spanner in Dynamic_engraver.
2208 * Fixed (measured) tremolo for Stem and Beam. Merged declarations
2209 stem-engraver.hh and chord-tremolo-engraver.hh into their .cc
2210 implementation file. Also fixed looks of Chord tremolo, input and
2211 implementation is still ugly.
2213 * Added *.yy and *.ll to TAGS, to that tags-find-replace doesn't omit
2219 * Fixed \specialkey and \normalkey. Updated documentation.
2226 * Fixed and cleaned-up Dynamic_engraver. Optionionally uses vanilla
2227 spanner instead of Dynamic_line_spanner.
2229 * Made gcc-2.95 compile fix in libc-extension.
2231 * Various fixes to Coriolan, score starts to look acceptable.
2233 * Moved optional text of crescendo into Crescendo spanner. Fixed horizontal
2234 and vertical alignment of dynamics.
2236 * Added new text crescendo spanners to Coriolan and made some fixes.
2237 If you're using timidity, use the -EO option to prevent notes get
2238 stuck. I'm not sure whose fault this is, Lily's MIDI output may be
2239 stretching the standard a bit.
2241 * Adjacent dynamic markings are now grouped on a horizontal line, but it's
2242 not perfect yet: they're always below the staff and no horizontal spacing
2243 is done. Also, character metrics of dynamics are still not used.
2244 See: input/test/crescendi.ly and input/test/dyn-line.ly
2246 * Cleaned up Span_dynamic_performer.
2253 * Fixed the page layout, reintroducing space for the header and
2254 trying to keep piece titles on the same page as the piece.
2255 The header and footer can now contain several lines.
2260 * Lily now also performs crescendi and decrescendi in MIDI output:
2261 Span_dynamic_performer in a slightly crappy way.
2263 * Added preliminary support for crescendi/decrescendi other than `hairpins',
2264 eg: `cresc. poco `a poco -- -- --'
2266 * Made MIDI tie performance fix.
2271 * Lily now performs absolute dynamics in MIDI output.
2273 * Included David's comments on opus47 in TODO.
2278 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
2279 fixes and remainder french horn-1,2; trombone-1,2;
2280 fagotto-1,2; timpani; and several fixes.
2285 * Remove some old doco from programmer/ and put on personal homepage.
2287 * Removed union-find from flower library.
2289 * Only quantise tie horizontal part inside the staff.
2296 * Report type errors for \property. Helps with converting 1.2 input
2298 * Use Scheme for Align_element; fixed graceAlignPosition
2299 and removed \property alignmentReference in the process.
2301 * Use generic properties for lyrics too. This fixes \property
2305 * Add relative distance for constraints between non-column items.
2307 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
2308 increased automatically.
2310 * Translators now only change properties of their own context. This
2311 removes the 2nd argument to Translator::get_property()
2313 * Bugfix for Metapost mode
2318 * Updates of glossary (Christian Mondrup)
2320 * Bugfix with bar number placement
2322 * Moved links to bibliography/ and misc/ to main index.
2327 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
2328 Slurs are now calculated just once.
2330 * Bezier_bow gets constants from paper. Still no sensible solution for
2331 magic asymmetry gradient step constants.
2333 * Reinstantiated tangent-controls, more flexible than ever. You can choose
2334 between area asymmetry and tangent-controls. My guess is, tangent controls
2335 will be junked in 1.3.30.
2337 * Slur area: only look at x-gradient.
2339 * Added credits for some symbols of as5/9 fonts.
2341 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
2343 * Bugfix: midi2ly put out recent version (ugh).
2348 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
2351 * Removed Gade score. To appear (shortly?) on Mutopia.
2353 * Make Bar_script_engraver look for typeVisibilityFunction (eg
2354 property barNumberVisibilityFunction). Changed the names of the Scheme
2355 functions to be understandable. See input/test/bar-script-visibility.ly
2357 * rewrite of class Molecule. It has now reached the ultimate quality
2358 plateau. All molecule data is now shared.
2363 * Update of the glossary by Christian Mondrup
2365 * Moved horn-concerto-3 out of tarball to private website, removed
2366 W.A.Mozart subdirectory.
2371 * Bugfix: don't make giant ties if the horizontal part of tie is near
2374 * Small optimizations to be a little more careful with mem usage.
2376 * Website change: put all examples in one directory.
2378 * Removed Atom as a separate type. Now use SCM, and since we use
2379 function composition, Atoms are immutable, so they don't have to be
2380 copied. This makes life easier, hopefully this is quicker and uses
2386 * Bezier_bow: minimise_enclosed_area
2394 * Tuplet-spanner slope calculation now looks better on tupletted rests
2395 (patch courtesy Laurent Martelli)
2397 * Bugfix (Staff_performer::new_instrument_str ()) check type of
2398 \property "instrument"
2400 * New mechanism for breaking lines: do not copy & prune the element
2401 property list separately, but combine these steps. Dramatically
2402 reduces memory usage for large scores.
2409 * Bugfix: font used in volta-spanner calculation.
2411 * Added simple selection list to webpage, inspired by sawmill.
2413 * Devised kludge for ascii 5 character font pitches.
2415 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
2420 * Plug memory leaks related to Moment:
2421 - Spacing_engraver::do_pre_move_processing ()
2422 - make_rational ()/make-rational
2423 - Paper_column::Paper_column ()
2425 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
2427 * Plug memory leak in Score_engraver::set_columns ()
2429 * Plug memory leak in Scheme_hash_table::set()
2431 * Plug memory leak in Score_element::molecule_extent ()
2433 * Bugfix: don't crash if a slur doesn't span anything.
2435 * Bugfix: don't crash if doing beams without a staff symbol.
2437 * Generic element property setting:
2439 \outputproperty #predicate #'symbol = #value
2441 Will set the element property symbol to value, for any elements that
2442 return true for PREDICATE. This allows you to virtually tweak *ANY*
2443 property of the output. Example in input/test/generic-output-property.ly
2448 * lilypond as as2ly: --help and --version to stdout. Regular identify
2449 to stderr. This fixes help2man's manpage generation.
2451 * configure: substitute full path for perl and guile in scripts.
2453 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
2455 * Bugfix: default font now user settable
2457 * as2text: handle plain ascii font, read from stdin, you can now do:
2459 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
2464 * Bugfix: second half of broken ties now are displayed again.
2466 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
2467 it horizontally on the clef.
2469 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
2471 * Bugfix: unbroken repeat barlines now work, eg. |:
2473 * Added Request_iterator to make more flexible constructions possible.
2477 * as2text: catch missing font/character errors, added default font, set text.
2479 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
2481 * Ascii output, minimal support:
2482 - AsciiScript Fonts: mf/*.af
2483 - Init files: ly/*-as.*ly
2484 - AsciiScript translation to text: scripts/as2text.scm
2485 - input/test/as.fly input/test/as1.fly
2486 - Output support: lily/lily.scm
2488 lilypond -f as -i init-as.fly input/test/as.fly
2494 * The horizontal part of ties will avoid collision with staff lines.
2496 * Plugged memory leak: don't protect Atom function.
2498 * Lookup cleanups. Made lots of functions static. Moved some code out
2506 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
2507 does not delete any of the file_ly*.tex.
2509 * Added header and footer support in ly2dvi.py
2514 * Added a ROADMAP file explaining the source directory layout.
2516 * Minor tweak in the feta 6 and 9 numeral
2518 * Moved files from lib/ to flower/
2520 * Removed Note_head_side class.
2522 * Updated the webpage to be a little more chatty.
2524 * Small Local_key_engraver optimization: only lookup timing engraver once.
2526 * Fixed dashed slurs
2528 * Rewrite of Slur code. Be much more picky about slur shapes. We try
2529 to offset the slur instead of bending it too much
2531 * Look at stem directions for tie direction.
2533 * Compound multimeasure rests. Put measures_i_ variable in an element
2534 property. Made the symbol a lot wider.
2536 * Time signature small cleanups.
2541 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
2544 * Breathing marks now have a direction by default.
2546 * Do set generic script properties.
2548 * Also put tuplet brackets under notes.
2550 * Score_element_info: only store origin of element, but not the path
2551 to parent translators. Saves a little memory, and removes some complexity.
2557 * Autobeaming in time sigs that don't have 1/4 beats fixed.
2559 * (De)crescendi should now work. (Thanks Michael)
2561 * Better error reporting for conflicting time signatures.
2563 * Line_number_engraver: output locations of note head
2564 definitions. Very handy when entering complicated scores.
2566 * Rewrote multi measure rest support: now they are entered as spanners
2567 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
2569 { \commandspanrequest \start "rest"
2571 \commandspanrequest \stop "rest"
2574 * Removed support of percent style repetitions.
2576 * Put texts outside the staff.
2580 * Getopt bugfix: don't assert on certain errors.
2582 * ly2dvi: Remove unnecessary space for the page headers.
2584 * Bugfix convert-mudela
2589 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
2592 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
2593 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
2594 \property tupletInvisible will stop all tuplet spanner creation.
2596 * Don't go berserk if tuplet spanner is on only one column.
2598 * Use SCMs & Smobs for Molecules & atoms. This uses less
2599 scm_(un)protect_object () calls, so the output stage should be faster.
2601 * Added \property tupletSpannerDuration, to make multiple tuplet signs
2604 * Some programming Errors in spacing are now caught. Lily does not
2605 hang when encountering degenerate springs.
2607 * Allow beams to start and end over rests
2611 * Fix disappearing clefs when clefs are not printed with a barline.
2616 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
2617 input/test/beam-control.fly
2618 * Added \context Voice to .fly and .sly; the default \context Staff is almost
2619 never what you expect
2620 * Fixed decision for .sly/.fly in lilypond-mode.
2625 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
2626 Cleanup mf-to-table.py
2628 * Fixed embarassing slur bug.
2633 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
2638 * lilypond-mode.el for emacs supersedes mudela-mode.el
2640 * Tuplet spanners don't collide with encompassing notes.
2642 * Gobbled Adobe parseAFM* code, for future use.
2644 * Big 1999 to 2000 search/replace.
2646 * Big interline to staff_space search/replace for mf files.
2648 * Removed Bow class, and split code into Tie and Slur
2650 * Don't put scripts on grace notes.
2652 * Font_metric uses SCM for name field.
2654 * Various compilation fixes.
2659 * Bugfix: beams with less than one (visible) stem
2661 * small fixes to pa.ly
2666 * Fixed bug that made multi-measure rest barnumber counts go wild.
2667 (even more scm2int/int2scm mixups!)
2669 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
2671 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
2676 * Remove Paper_def calls in bezier-bow.cc
2678 * Remove data members of Tuplet_spanner, Volta_spanner
2680 * hang_on_clef, property hangOnClef removed
2682 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
2683 function to determine breaking behavior.
2685 * More Scheme typechecking.
2687 * Be strict about the difference between strings and symbols for conversion.
2689 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
2692 * Partial French translation, courtesy Laurent Martelli.
2694 * Small corrections in NL translation.
2699 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
2700 we have a longa note head. noteHeadStyle = "harmonic" is not
2701 supported anymore. (for now, that is)
2703 * Reference manual update. Document \properties with examples
2705 * fix mudela-book --help
2707 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
2708 Key_item::c0_position_
2710 * Clef_engraver general cleanup. Use alists (\property
2711 supportedClefTypes, clefPitches) for clef types.
2713 * Use progress_indication () for progress. Don't include <iostream.h> directly
2714 Don't include <string.h>, <math.h> from headers.
2720 * \property stemCentered (boolean): centers stem on note head. See
2721 input/test/stem-centered.ly
2723 * input/trip.ly, small test of lots of features.
2725 * \property Staff.collisionMergeDotted: merge equal noteheads
2726 with different dot count. See input/test/collision-merge-dotted.fly
2728 * Dotted rest bugfix
2730 * Don't crash if a slur does not span any notes.
2732 * Volta repeats fixed.
2734 * cleanup of Note_heads_engraver
2736 * removed dots_i_ member of Dots
2740 * Fixed cross staff slurs. It seems that cross-staff sign
2746 * Fixed bug in stem code. Stem in chords works again. Small
2749 * Use element properties for Staff_symbol.
2751 * \property sparseTies (boolean). Only make one tie in the
2752 middle for tied chords.
2754 * Junked Directional_spanner, Column_info.
2755 Directional_element now is element interface `Directional_element_interface'
2757 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
