2 ++ b/CHANGES Tue Mar 14 15:16:52 2000
7 * Cleanups for Dynamic_engraver and Dynamic_line_spanner.
9 * Warn if last column in score is musical. Helps catch programming errors.
11 * Spanner::spanned_drul_ now is private.
18 * Embedded newlines in text items are now allowed. This helps avoiding
19 TeX-hacking in some cases. See input/test/coriolan-margin.ly
21 * Fixed stupid x-y interchange bug for staff-bracket. This fixes
22 placement of staff-brackets.
24 * Fixed bracket/arch-thickness interchange bug, and made bracket a bit
27 * Fixed slur/bezier-beautiful name mismatch. This should fix the steep
28 slurs that were apparently reintroduced in 1.3.29.
33 * Made some small fixes to Coriolan.
38 * Removed duplicate lily/output-property-engraver.hh.
40 * Removed optional use of vanilla spanner in Dynamic_engraver.
42 * Fixed (measured) tremolo for Stem and Beam. Merged declarations
43 stem-engraver.hh and chord-tremolo-engraver.hh into their .cc
44 implementation file. Also fixed looks of Chord tremolo, input and
45 implementation is still ugly.
47 * Added *.yy and *.ll to TAGS, to that tags-find-replace doesn't omit
53 * Fixed and cleaned-up Dynamic_engraver. Optionionally uses vanilla
54 spanner instead of Dynamic_line_spanner.
56 * Made gcc-2.95 compile fix in libc-extension.
58 * Various fixes to Coriolan, score starts to look acceptable.
63 * Moved optional text of crescendo into Crescendo spanner. Fixed horizontal
64 and vertical alignment of dynamics.
66 * Added new text crescendo spanners to Coriolan and made some fixes.
67 If you're using timidity, use the -EO option to prevent notes get
68 stuck. I'm not sure whose fault this is, Lily's MIDI output may be
69 stretching the standard a bit.
74 * Adjacent dynamic markings are now grouped on a horizontal line, but it's
75 not perfect yet: they're always below the staff and no horizontal spacing
76 is done. Also, character metrics of dynamics are still not used.
77 See: input/test/crescendi.ly and input/test/dyn-line.ly
79 * Cleaned up Span_dynamic_performer.
86 * Fixed the page layout, reintroducing space for the header and
87 trying to keep piece titles on the same page as the piece.
88 The header and footer can now contain several lines.
93 * Lily now also performs crescendi and decrescendi in MIDI output:
94 Span_dynamic_performer (bit scrappy).
96 * Added preliminary support for crescendi/decrescendi other than `hairpins',
97 eg: `cresc. poco `a poco -- -- --'
99 * Made MIDI tie performance fix.
104 * Lily now performs absolute dynamics in MIDI output.
106 * Included David's comments on opus47 in TODO.
111 * More Coriolan: flute-1,2; oboe-1,2; clarinet-1,2;
112 fixes and remainder french horn-1,2; trombone-1,2;
113 fagotto-1,2; timpani; and several fixes.
118 * Remove some old doco from programmer/ and put on personal homepage.
120 * Removed union-find from flower library.
122 * Only quantise tie horizontal part inside the staff.
129 * Report type errors for \property. Helps with converting 1.2 input
131 * Use Scheme for Align_element; fixed graceAlignPosition
132 and removed \property alignmentReference in the process.
134 * Use generic properties for lyrics too. This fixes \property
138 * Add relative distance for constraints between non-column items.
140 * Automatic \marks: use "\mark ; ". The mark numbers or letters are
141 increased automatically.
143 * Translators now only change properties of their own context. This
144 removes the 2nd argument to Translator::get_property()
146 * Bugfix for Metapost mode
151 * Updates of glossary (Christian Mondrup)
153 * Bugfix with bar number placement
155 * Moved links to bibliography/ and misc/ to main index.
160 * Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
161 Slurs are now calculated just once.
163 * Bezier_bow gets constants from paper. Still no sensible solution for
164 magic asymmetry gradient step constants.
166 * Reinstantiated tangent-controls, more flexible than ever. You can choose
167 between area asymmetry and tangent-controls. My guess is, tangent controls
168 will be junked in 1.3.30.
170 * Slur area: only look at x-gradient.
172 * Added credits for some symbols of as5/9 fonts.
174 * Bugfix: don't make almost flat slurs, change in de-uglyfy slur.
176 * Bugfix: midi2ly put out recent version (ugh).
181 * Bugfix: don't forget to process staffSpace and numberOfStaffLines
184 * Removed Gade score. To appear (shortly?) on Mutopia.
186 * Make Bar_script_engraver look for typeVisibilityFunction (eg
187 property barNumberVisibilityFunction). Changed the names of the Scheme
188 functions to be understandable. See input/test/bar-script-visibility.ly
190 * rewrite of class Molecule. It has now reached the ultimate quality
191 plateau. All molecule data is now shared.
196 * Update of the glossary by Christian Mondrup
198 * Moved horn-concerto-3 out of tarball to private website, removed
199 W.A.Mozart subdirectory.
204 * Bugfix: don't make giant ties if the horizontal part of tie is near
207 * Small optimizations to be a little more careful with mem usage.
209 * Website change: put all examples in one directory.
211 * Removed Atom as a separate type. Now use SCM, and since we use
212 function composition, Atoms are immutable, so they don't have to be
213 copied. This makes life easier, hopefully this is quicker and uses
219 * Bezier_bow: minimise_enclosed_area
227 * Tuplet-spanner slope calculation now looks better on tupletted rests
228 (patch courtesy Laurent Martelli)
230 * Bugfix (Staff_performer::new_instrument_str ()) check type of
231 \property "instrument"
233 * New mechanism for breaking lines: do not copy & prune the element
234 property list separately, but combine these steps. Dramatically
235 reduces memory usage for large scores.
242 * Bugfix: font used in volta-spanner calculation.
244 * Added simple selection list to webpage, inspired by sawmill.
246 * Devised kludge for ascii 5 character font pitches.
248 * Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.
253 * Plug memory leaks related to Moment:
254 - Spacing_engraver::do_pre_move_processing ()
255 - make_rational ()/make-rational
256 - Paper_column::Paper_column ()
258 * Plug memory leak in Paper_outputter::output_{String,Real,int}_def()
260 * Plug memory leak in Score_engraver::set_columns ()
262 * Plug memory leak in Scheme_hash_table::set()
264 * Plug memory leak in Score_element::molecule_extent ()
266 * Bugfix: don't crash if a slur doesn't span anything.
268 * Bugfix: don't crash if doing beams without a staff symbol.
270 * Generic element property setting:
272 \outputproperty #predicate #'symbol = #value
274 Will set the element property symbol to value, for any elements that
275 return true for PREDICATE. This allows you to virtually tweak *ANY*
276 property of the output. Example in input/test/generic-output-property.ly
281 * lilypond as as2ly: --help and --version to stdout. Regular identify
282 to stderr. This fixes help2man's manpage generation.
284 * configure: substitute full path for perl and guile in scripts.
286 * Added ascii slur and volta. There seems to be a Lily bug in volta placement.
288 * Bugfix: default font now user settable
290 * as2text: handle plain ascii font, read from stdin, you can now do:
292 echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text
297 * Bugfix: second half of broken ties now are displayed again.
299 * Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
300 it horizontally on the clef.
302 * Added Tie_column spanner. Ties in tied chords now get proper directionsa.
304 * Bugfix: unbroken repeat barlines now work, eg. |:
306 * Added Request_iterator to make more flexible constructions possible.
310 * as2text: catch missing font/character errors, added default font, set text.
312 * New ascii fonts and glyphs: as5 as-numeral4 as-braces9
314 * Ascii output, minimal support:
315 - AsciiScript Fonts: mf/*.af
316 - Init files: ly/*-as.*ly
317 - AsciiScript translation to text: scripts/as2text.scm
318 - input/test/as.fly input/test/as1.fly
319 - Output support: lily/lily.scm
321 lilypond -f as -i init-as.fly input/test/as.fly
327 * The horizontal part of ties will avoid collision with staff lines.
329 * Plugged memory leak: don't protect Atom function.
331 * Lookup cleanups. Made lots of functions static. Moved some code out
339 * Bugfix: ly2dvi.py exits succesfully when encountering --help and
340 does not delete any of the file_ly*.tex.
342 * Added header and footer support in ly2dvi.py
347 * Added a ROADMAP file explaining the source directory layout.
349 * Minor tweak in the feta 6 and 9 numeral
351 * Moved files from lib/ to flower/
353 * Removed Note_head_side class.
355 * Updated the webpage to be a little more chatty.
357 * Small Local_key_engraver optimization: only lookup timing engraver once.
361 * Rewrite of Slur code. Be much more picky about slur shapes. We try
362 to offset the slur instead of bending it too much
364 * Look at stem directions for tie direction.
366 * Compound multimeasure rests. Put measures_i_ variable in an element
367 property. Made the symbol a lot wider.
369 * Time signature small cleanups.
374 * Symbols opposite to stem (eg marcato) now get the proper glyph in up
377 * Breathing marks now have a direction by default.
379 * Do set generic script properties.
381 * Also put tuplet brackets under notes.
383 * Score_element_info: only store origin of element, but not the path
384 to parent translators. Saves a little memory, and removes some complexity.
390 * Autobeaming in time sigs that don't have 1/4 beats fixed.
392 * (De)crescendi should now work. (Thanks Michael)
394 * Better error reporting for conflicting time signatures.
396 * Line_number_engraver: output locations of note head
397 definitions. Very handy when entering complicated scores.
399 * Rewrote multi measure rest support: now they are entered as spanners
400 (\commandspanrequest \start "rest"). RXXXX is an abbreviation for
402 { \commandspanrequest \start "rest"
404 \commandspanrequest \stop "rest"
407 * Removed support of percent style repetitions.
409 * Put texts outside the staff.
413 * Getopt bugfix: don't assert on certain errors.
415 * ly2dvi: Remove unnecessary space for the page headers.
417 * Bugfix convert-mudela
422 * Bugfix in lilypond-mode.el: eval-buffering now uses file name and
425 * Scrapped tupletVisibility property. Now use tupletNumberVisibility,
426 tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
427 \property tupletInvisible will stop all tuplet spanner creation.
429 * Don't go berserk if tuplet spanner is on only one column.
431 * Use SCMs & Smobs for Molecules & atoms. This uses less
432 scm_(un)protect_object () calls, so the output stage should be faster.
434 * Added \property tupletSpannerDuration, to make multiple tuplet signs
437 * Some programming Errors in spacing are now caught. Lily does not
438 hang when encountering degenerate springs.
440 * Allow beams to start and end over rests
444 * Fix disappearing clefs when clefs are not printed with a barline.
449 * SCM properties beamHeight and beamVerticalposition now use half-spaces:
450 input/test/beam-control.fly
451 * Added \context Voice to .fly and .sly; the default \context Staff is almost
452 never what you expect
453 * Fixed decision for .sly/.fly in lilypond-mode.
458 * Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
459 Cleanup mf-to-table.py
461 * Fixed embarassing slur bug.
466 * lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings
471 * lilypond-mode.el for emacs supersedes mudela-mode.el
473 * Tuplet spanners don't collide with encompassing notes.
475 * Gobbled Adobe parseAFM* code, for future use.
477 * Big 1999 to 2000 search/replace.
479 * Big interline to staff_space search/replace for mf files.
481 * Removed Bow class, and split code into Tie and Slur
483 * Don't put scripts on grace notes.
485 * Font_metric uses SCM for name field.
487 * Various compilation fixes.
492 * Bugfix: beams with less than one (visible) stem
494 * small fixes to pa.ly
499 * Fixed bug that made multi-measure rest barnumber counts go wild.
500 (even more scm2int/int2scm mixups!)
502 * mutopia/J.S.Bach/pa.ly: organ score (for my father)
504 * small fix to mutopia/J.S.Bach/Duette/violino-ii.ly
509 * Remove Paper_def calls in bezier-bow.cc
511 * Remove data members of Tuplet_spanner, Volta_spanner
513 * hang_on_clef, property hangOnClef removed
515 * Bar::type_str_ mode into element property `glyph'. Use a Scheme
516 function to determine breaking behavior.
518 * More Scheme typechecking.
520 * Be strict about the difference between strings and symbols for conversion.
522 * Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
525 * Partial French translation, courtesy Laurent Martelli.
527 * Small corrections in NL translation.
532 * Added mensural note heads (noteHeadStyle = "mensural") Additionally,
533 we have a longa note head. noteHeadStyle = "harmonic" is not
534 supported anymore. (for now, that is)
536 * Reference manual update. Document \properties with examples
538 * fix mudela-book --help
540 * Use element properties for Text_item::text_str_, Clef_item::symbol_,
541 Key_item::c0_position_
543 * Clef_engraver general cleanup. Use alists (\property
544 supportedClefTypes, clefPitches) for clef types.
546 * Use progress_indication () for progress. Don't include <iostream.h> directly
547 Don't include <string.h>, <math.h> from headers.
553 * \property stemCentered (boolean): centers stem on note head. See
554 input/test/stem-centered.ly
556 * input/trip.ly, small test of lots of features.
558 * \property Staff.collisionMergeDotted: merge equal noteheads
559 with different dot count. See input/test/collision-merge-dotted.fly
563 * Don't crash if a slur does not span any notes.
565 * Volta repeats fixed.
567 * cleanup of Note_heads_engraver
569 * removed dots_i_ member of Dots

579 * Fixed bug in stem code. Stem in chords works again. Small
582 * Use element properties for Staff_symbol.
584 * \property sparseTies (boolean). Only make one tie in the
585 middle for tied chords.
587 * Junked Directional_spanner, Column_info.
588 Directional_element now is element interface `Directional_element_interface'
590 * cleanup: use to_boolean () iso. gh_boolean_p && gh_bool2scm
