5 * Update of the glossary by Christian Mondrup
7 * Moved horn-concerto-3 out of tarball to private website, removed
8 W.A.Mozart subdirectory.
13 * Bugfix: don't make giant ties if the horizontal part of tie is near
16 * Small optimizations to be a little more careful with mem usage.
18 * Website change: put all examples in one directory.
20 * Removed Atom as a separate type. Now use SCM, and since we use
21 function composition, Atoms are immutable, so they don't have to be
22 copied. This makes life easier, hopefully this is quicker and uses
28 * Bezier_bow: minimise_enclosed_area
36 * Tuplet-spanner slope calculation now looks better on tupletted rests
37 (patch courtesy Laurent Martelli)
39 * Bugfix (Staff_performer::new_instrument_str ()) check type of
40 \property "instrument"
42 * New mechanism for breaking lines: do not copy & prune the element
43 property list separately, but combine these steps. Dramatically
44 reduces memory usage for large scores.
51 * Bugfix: font used in volta-spanner calculation.
53 * Added simple selection list to webpage, inspired by sawmill.
55 * Devised kludge for ascii 5 character font pitches.
57 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
62 * Plug memory leaks related to Moment:
63 - Spacing_engraver::do_pre_move_processing ()
64 - make_rational ()/make-rational
65 - Paper_column::Paper_column ()
67 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
69 * Plug memory leak in Score_engraver::set_columns ()
71 * Plug memory leak in Scheme_hash_table::set()
73 * Plug memory leak in Score_element::molecule_extent ()
75 * Bugfix: don't crash if a slur doesn't span anything.
77 * Bugfix: don't crash if doing beams without a staff symbol.
79 * Generic element property setting:
81 \outputproperty #predicate #'symbol = #value
83 Will set the element property symbol to value, for any elements that
84 return true for PREDICATE. This allows you to virtually tweak *ANY*
85 property of the output. Example in input/test/generic-output-property.ly
90 * lilypond as as2ly: --help and --version to stdout. Regular identify
91 to stderr. This fixes help2man's manpage generation.
93 * configure: substitute full path for perl and guile in scripts.
95 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
97 * Bugfix: default font now user settable
99 * as2text: handle plain ascii font, read from stdin, you can now do:
101 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
106 * Bugfix: second half of broken ties now are displayed again.
108 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
109 it horizontally on the clef.
111 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
113 * Bugfix: unbroken repeat barlines now work, eg. |:
115 * Added Request_iterator to make more flexible constructions possible.
119 * as2text: catch missing font/character errors, added default font, set text.
121 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
123 * Ascii output, minimal support:
124 - AsciiScript Fonts: mf/*.af
125 - Init files: ly/*-as.*ly
126 - AsciiScript translation to text: scripts/as2text.scm
127 - input/test/as.fly input/test/as1.fly
128 - Output support: lily/lily.scm
130 lilypond -f as -i init-as.fly input/test/as.fly
136 * The horizontal part of ties will avoid collision with staff lines.
138 * Plugged memory leak: don't protect Atom function.
140 * Lookup cleanups. Made lots of functions static. Moved some code out
148 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
149 does not delete any of the file_ly*.tex.
151 * Added header and footer support in ly2dvi.py
156 * Added a ROADMAP file explaining the source directory layout.
158 * Minor tweak in the feta 6 and 9 numeral
160 * Moved files from lib/ to flower/
162 * Removed Note_head_side class.
164 * Updated the webpage to be a little more chatty.
166 * Small Local_key_engraver optimization: only lookup timing engraver once.
170 * Rewrite of Slur code. Be much more picky about slur shapes. We try
171 to offset the slur instead of bending it too much
173 * Look at stem directions for tie direction.
175 * Compound multimeasure rests. Put measures_i_ variable in an element
176 property. Made the symbol a lot wider.
178 * Time signature small cleanups.
183 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
186 * Breathing marks now have a direction by default.
188 * Do set generic script properties.
190 * Also put tuplet brackets under notes.
192 * Score_element_info: only store origin of element, but not the path
193 to parent translators. Saves a little memory, and removes some complexity.
199 * Autobeaming in time sigs that don't have 1/4 beats fixed.
201 * (De)crescendi should now work. (Thanks Michael)
203 * Better error reporting for conflicting time signatures.
205 * Line_number_engraver: output locations of note head
206 definitions. Very handy when entering complicated scores.
208 * Rewrote multi measure rest support: now they are entered as spanners
209 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
211 { \commandspanrequest \start "rest"
213 \commandspanrequest \stop "rest"
216 * Removed support of percent style repetitions.
218 * Put texts outside the staff.
222 * Getopt bugfix: don't assert on certain errors.
224 * ly2dvi: Remove unnecessary space for the page headers.
226 * Bugfix convert-mudela
231 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
234 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
235 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
236 \property tupletInvisible will stop all tuplet spanner creation.
238 * Don't go berserk if tuplet spanner is on only one column.
240 * Use SCMs & Smobs for Molecules & atoms. This uses less
241 scm_(un)protect_object () calls, so the output stage should be faster.
243 * Added \property tupletSpannerDuration, to make multiple tuplet signs
246 * Some programming Errors in spacing are now caught. Lily does not
247 hang when encountering degenerate springs.
249 * Allow beams to start and end over rests
253 * Fix disappearing clefs when clefs are not printed with a barline.
258 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
259 input/test/beam-control.fly
260 * Added \context Voice to .fly and .sly; the default \context Staff is almost
261 never what you expect
262 * Fixed decision for .sly/.fly in lilypond-mode.
267 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
268 Cleanup mf-to-table.py
270 * Fixed embarassing slur bug.
275 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
280 * lilypond-mode.el for emacs supersedes mudela-mode.el
282 * Tuplet spanners don't collide with encompassing notes.
284 * Gobbled Adobe parseAFM* code, for future use.
286 * Big 1999 to 2000 search/replace.
288 * Big interline to staff_space search/replace for mf files.
290 * Removed Bow class, and split code into Tie and Slur
292 * Don't put scripts on grace notes.
294 * Font_metric uses SCM for name field.
296 * Various compilation fixes.
301 * Bugfix: beams with less than one (visible) stem
303 * small fixes to pa.ly
308 * Fixed bug that made multi-measure rest barnumber counts go wild.
309 (even more scm2int/int2scm mixups!)
311 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
313 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
318 * Remove Paper_def calls in bezier-bow.cc
320 * Remove data members of Tuplet_spanner, Volta_spanner
322 * hang_on_clef, property hangOnClef removed
324 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
325 function to determine breaking behavior.
327 * More Scheme typechecking.
329 * Be strict about the difference between strings and symbols for conversion.
331 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
334 * Partial French translation, courtesy Laurent Martelli.
336 * Small corrections in NL translation.
341 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
342 we have a longa note head. noteHeadStyle = "harmonic" is not
343 supported anymore. (for now, that is)
345 * Reference manual update. Document \properties with examples
347 * fix mudela-book --help
349 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
350 Key_item::c0_position_
352 * Clef_engraver general cleanup. Use alists (\property
353 supportedClefTypes, clefPitches) for clef types.
355 * Use progress_indication () for progress. Don't include <iostream.h> directly
356 Don't include <string.h>, <math.h> from headers.
362 * \property stemCentered (boolean): centers stem on note head. See
363 input/test/stem-centered.ly
365 * input/trip.ly, small test of lots of features.
367 * \property Staff.collisionMergeDotted: merge equal noteheads
368 with different dot count. See input/test/collision-merge-dotted.fly
372 * Don't crash if a slur does not span any notes.
374 * Volta repeats fixed.
376 * cleanup of Note_heads_engraver
378 * removed dots_i_ member of Dots
382 * Fixed cross staff slurs. It seems that cross-staff sign
388 * Fixed bug in stem code. Stem in chords works again. Small
391 * Use element properties for Staff_symbol.
393 * \property sparseTies (boolean). Only make one tie in the
394 middle for tied chords.
396 * Junked Directional_spanner, Column_info.
397 Directional_element now is element interface `Directional_element_interface'
399 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
