4 * Fixed the page layout, reintroducing space for the header and
5 trying to keep piece titles on the same page as the piece.
6 The header and footer can now contain several lines.
11 * Span_dynamic_performer; perform crescendi/decrescendi. Bit scrappy.
13 * Preliminary support for crescendi/decrescendi other than `hairpins', eg:
14 `cresc. poco `a poco -- -- --'
16 * Tie performance fix.
21 * Dynamic_performer: performs absolute dynamic requests.
23 * David's comments on opus47
28 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
29 fixes and remainder french horn-1,2; trombone-1,2;
30 fagotto-1,2; timpani; and several fixes.
35 * Remove some old doco from programmer/ and put on personal homepage.
37 * Removed union-find from flower library.
39 * Only quantise tie horizontal part inside the staff.
46 * Report type errors for \property. Helps with converting 1.2 input
48 * Use Scheme for Align_element; fixed graceAlignPosition
49 and removed \property alignmentReference in the process.
51 * Use generic properties for lyrics too. This fixes \property
55 * Add relative distance for constraints between non-column items.
57 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
58 increased automatically.
60 * Translators now only change properties of their own context. This
61 removes the 2nd argument to Translator::get_property()
63 * Bugfix for Metapost mode
68 * Updates of glossary (Christian Mondrup)
70 * Bugfix with bar number placement
72 * Moved links to bibliography/ and misc/ to main index.
77 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
78 Slurs are now calculated just once.
80 * Bezier_bow gets constants from paper. Still no sensible solution for
81 magic asymmetry gradient step constants.
83 * Reinstantiated tangent-controls, more flexible than ever. You can choose
84 between area asymmetry and tangent-controls. My guess is, tangent controls
85 will be junked in 1.3.30.
87 * Slur area: only look at x-gradient.
89 * Added credits for some symbols of as5/9 fonts.
91 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
93 * Bugfix: midi2ly put out recent version (ugh).
98 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
101 * Removed Gade score. To appear (shortly?) on Mutopia.
103 * Make Bar_script_engraver look for typeVisibilityFunction (eg
104 property barNumberVisibilityFunction). Changed the names of the Scheme
105 functions to be understandable. See input/test/bar-script-visibility.ly
107 * rewrite of class Molecule. It has now reached the ultimate quality
108 plateau. All molecule data is now shared.
113 * Update of the glossary by Christian Mondrup
115 * Moved horn-concerto-3 out of tarball to private website, removed
116 W.A.Mozart subdirectory.
121 * Bugfix: don't make giant ties if the horizontal part of tie is near
124 * Small optimizations to be a little more careful with mem usage.
126 * Website change: put all examples in one directory.
128 * Removed Atom as a separate type. Now use SCM, and since we use
129 function composition, Atoms are immutable, so they don't have to be
130 copied. This makes life easier, hopefully this is quicker and uses
136 * Bezier_bow: minimise_enclosed_area
144 * Tuplet-spanner slope calculation now looks better on tupletted rests
145 (patch courtesy Laurent Martelli)
147 * Bugfix (Staff_performer::new_instrument_str ()) check type of
148 \property "instrument"
150 * New mechanism for breaking lines: do not copy & prune the element
151 property list separately, but combine these steps. Dramatically
152 reduces memory usage for large scores.
159 * Bugfix: font used in volta-spanner calculation.
161 * Added simple selection list to webpage, inspired by sawmill.
163 * Devised kludge for ascii 5 character font pitches.
165 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
170 * Plug memory leaks related to Moment:
171 - Spacing_engraver::do_pre_move_processing ()
172 - make_rational ()/make-rational
173 - Paper_column::Paper_column ()
175 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
177 * Plug memory leak in Score_engraver::set_columns ()
179 * Plug memory leak in Scheme_hash_table::set()
181 * Plug memory leak in Score_element::molecule_extent ()
183 * Bugfix: don't crash if a slur doesn't span anything.
185 * Bugfix: don't crash if doing beams without a staff symbol.
187 * Generic element property setting:
189 \outputproperty #predicate #'symbol = #value
191 Will set the element property symbol to value, for any elements that
192 return true for PREDICATE. This allows you to virtually tweak *ANY*
193 property of the output. Example in input/test/generic-output-property.ly
198 * lilypond as as2ly: --help and --version to stdout. Regular identify
199 to stderr. This fixes help2man's manpage generation.
201 * configure: substitute full path for perl and guile in scripts.
203 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
205 * Bugfix: default font now user settable
207 * as2text: handle plain ascii font, read from stdin, you can now do:
209 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
214 * Bugfix: second half of broken ties now are displayed again.
216 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
217 it horizontally on the clef.
219 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
221 * Bugfix: unbroken repeat barlines now work, eg. |:
223 * Added Request_iterator to make more flexible constructions possible.
227 * as2text: catch missing font/character errors, added default font, set text.
229 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
231 * Ascii output, minimal support:
232 - AsciiScript Fonts: mf/*.af
233 - Init files: ly/*-as.*ly
234 - AsciiScript translation to text: scripts/as2text.scm
235 - input/test/as.fly input/test/as1.fly
236 - Output support: lily/lily.scm
238 lilypond -f as -i init-as.fly input/test/as.fly
244 * The horizontal part of ties will avoid collision with staff lines.
246 * Plugged memory leak: don't protect Atom function.
248 * Lookup cleanups. Made lots of functions static. Moved some code out
256 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
257 does not delete any of the file_ly*.tex.
259 * Added header and footer support in ly2dvi.py
264 * Added a ROADMAP file explaining the source directory layout.
266 * Minor tweak in the feta 6 and 9 numeral
268 * Moved files from lib/ to flower/
270 * Removed Note_head_side class.
272 * Updated the webpage to be a little more chatty.
274 * Small Local_key_engraver optimization: only lookup timing engraver once.
278 * Rewrite of Slur code. Be much more picky about slur shapes. We try
279 to offset the slur instead of bending it too much
281 * Look at stem directions for tie direction.
283 * Compound multimeasure rests. Put measures_i_ variable in an element
284 property. Made the symbol a lot wider.
286 * Time signature small cleanups.
291 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
294 * Breathing marks now have a direction by default.
296 * Do set generic script properties.
298 * Also put tuplet brackets under notes.
300 * Score_element_info: only store origin of element, but not the path
301 to parent translators. Saves a little memory, and removes some complexity.
307 * Autobeaming in time sigs that don't have 1/4 beats fixed.
309 * (De)crescendi should now work. (Thanks Michael)
311 * Better error reporting for conflicting time signatures.
313 * Line_number_engraver: output locations of note head
314 definitions. Very handy when entering complicated scores.
316 * Rewrote multi measure rest support: now they are entered as spanners
317 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
319 { \commandspanrequest \start "rest"
321 \commandspanrequest \stop "rest"
324 * Removed support of percent style repetitions.
326 * Put texts outside the staff.
330 * Getopt bugfix: don't assert on certain errors.
332 * ly2dvi: Remove unnecessary space for the page headers.
334 * Bugfix convert-mudela
339 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
342 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
343 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
344 \property tupletInvisible will stop all tuplet spanner creation.
346 * Don't go berserk if tuplet spanner is on only one column.
348 * Use SCMs & Smobs for Molecules & atoms. This uses less
349 scm_(un)protect_object () calls, so the output stage should be faster.
351 * Added \property tupletSpannerDuration, to make multiple tuplet signs
354 * Some programming Errors in spacing are now caught. Lily does not
355 hang when encountering degenerate springs.
357 * Allow beams to start and end over rests
361 * Fix disappearing clefs when clefs are not printed with a barline.
366 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
367 input/test/beam-control.fly
368 * Added \context Voice to .fly and .sly; the default \context Staff is almost
369 never what you expect
370 * Fixed decision for .sly/.fly in lilypond-mode.
375 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
376 Cleanup mf-to-table.py
378 * Fixed embarassing slur bug.
383 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
388 * lilypond-mode.el for emacs supersedes mudela-mode.el
390 * Tuplet spanners don't collide with encompassing notes.
392 * Gobbled Adobe parseAFM* code, for future use.
394 * Big 1999 to 2000 search/replace.
396 * Big interline to staff_space search/replace for mf files.
398 * Removed Bow class, and split code into Tie and Slur
400 * Don't put scripts on grace notes.
402 * Font_metric uses SCM for name field.
404 * Various compilation fixes.
409 * Bugfix: beams with less than one (visible) stem
411 * small fixes to pa.ly
416 * Fixed bug that made multi-measure rest barnumber counts go wild.
417 (even more scm2int/int2scm mixups!)
419 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
421 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
426 * Remove Paper_def calls in bezier-bow.cc
428 * Remove data members of Tuplet_spanner, Volta_spanner
430 * hang_on_clef, property hangOnClef removed
432 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
433 function to determine breaking behavior.
435 * More Scheme typechecking.
437 * Be strict about the difference between strings and symbols for conversion.
439 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
442 * Partial French translation, courtesy Laurent Martelli.
444 * Small corrections in NL translation.
449 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
450 we have a longa note head. noteHeadStyle = "harmonic" is not
451 supported anymore. (for now, that is)
453 * Reference manual update. Document \properties with examples
455 * fix mudela-book --help
457 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
458 Key_item::c0_position_
460 * Clef_engraver general cleanup. Use alists (\property
461 supportedClefTypes, clefPitches) for clef types.
463 * Use progress_indication () for progress. Don't include <iostream.h> directly
464 Don't include <string.h>, <math.h> from headers.
470 * \property stemCentered (boolean): centers stem on note head. See
471 input/test/stem-centered.ly
473 * input/trip.ly, small test of lots of features.
475 * \property Staff.collisionMergeDotted: merge equal noteheads
476 with different dot count. See input/test/collision-merge-dotted.fly
480 * Don't crash if a slur does not span any notes.
482 * Volta repeats fixed.
484 * cleanup of Note_heads_engraver
486 * removed dots_i_ member of Dots
490 * Fixed cross staff slurs. It seems that cross-staff sign
496 * Fixed bug in stem code. Stem in chords works again. Small
499 * Use element properties for Staff_symbol.
501 * \property sparseTies (boolean). Only make one tie in the
502 middle for tied chords.
504 * Junked Directional_spanner, Column_info.
505 Directional_element now is element interface `Directional_element_interface'
507 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
