release: 1.3.30

[lilypond.git] / CHANGES

1.3.29.hwn1
===========

* Report type errors for \property. Helps with converting 1.2 input

* Use Scheme for Align_element; fixed graceAlignPosition 
and removed \property alignmentReference in the process.

* Use generic properties for lyrics too.  This fixes \property
Lyrics.textStyle


* Add relative distance for constraints between non-column items.

* Automatic \marks: use "\mark ; ". The mark numbers or letters are
increased automatically.

* Translators now only change properties of their own context. This
removes the 2nd argument to Translator::get_property()

* Bugfix for Metapost mode

1.3.29.uu1
==========

* Updates of glossary  (Christian Mondrup)

* Bugfix with bar number placement

* Moved links to bibliography/ and misc/ to main index.

1.3.29
======

* Moved Slur-specific code from Bezier_bow to Slur and Slur_bezier_bow.
  Slurs are now calculated just once.

* Bezier_bow gets constants from paper.  Still no sensible solution for
  magic asymmetry gradient step constants.

* Reinstantiated tangent-controls, more flexible than ever.  You can choose
  between area asymmetry and tangent-controls.  My guess is, tangent controls
  will be junked in 1.3.30.

* Slur area: only look at x-gradient.

* Added credits for some symbols of as5/9 fonts.

* Bugfix: don't make almost flat slurs, change in de-uglyfy slur.  

* Bugfix: midi2ly put out recent version (ugh).

1.3.28.hwn2
===========

* Bugfix: don't forget to process staffSpace and numberOfStaffLines
properties.

* Removed Gade score. To appear (shortly?) on Mutopia. 

* Make Bar_script_engraver look for typeVisibilityFunction (eg
property barNumberVisibilityFunction). Changed the names of the Scheme
functions to be understandable. See input/test/bar-script-visibility.ly

* rewrite of class Molecule. It has now reached the ultimate quality
plateau. All molecule data is now shared.

1.3.28
======

* Update of the glossary by Christian Mondrup 

* Moved horn-concerto-3 out of tarball to private website, removed
W.A.Mozart subdirectory.

1.3.27.hwn1
===========

* Bugfix: don't make giant ties if the horizontal part of tie is near
the center.

* Small optimizations to be a little more careful with mem usage. 

* Website change: put all examples in one directory.

* Removed Atom as a separate type.  Now use SCM, and since we use
function composition, Atoms are immutable, so they don't have to be
copied. This makes life easier, hopefully this is quicker and uses
less memory.

1.3.27.jcn1
===========

* Bezier_bow: minimise_enclosed_area

1.3.27
======

1.3.26.hwn4
===========

* Tuplet-spanner slope calculation now looks better on tupletted rests
(patch courtesy Laurent Martelli)

* Bugfix (Staff_performer::new_instrument_str ()) check type of
\property "instrument"

* New mechanism for breaking lines: do not copy & prune the element
property list separately, but combine these steps. Dramatically
reduces memory usage for large scores.

1.3.27
======
1.3.26.jcn2
===========

* Bugfix: font used in volta-spanner calculation.

* Added simple selection list to webpage, inspired by sawmill.
 
* Devised kludge for ascii 5 character font pitches.
 
* Substitutions: interline, 1997,1998, @stack.nl and small typo fixes.

1.3.26.hwn1
===========

* Plug memory leaks related to Moment:
  - Spacing_engraver::do_pre_move_processing ()
  - make_rational ()/make-rational
  - Paper_column::Paper_column ()

* Plug memory leak in Paper_outputter::output_{String,Real,int}_def()

* Plug memory leak in Score_engraver::set_columns ()

* Plug memory leak in Scheme_hash_table::set()

* Plug memory leak in Score_element::molecule_extent ()

* Bugfix: don't crash if a slur doesn't span anything.

* Bugfix: don't crash if doing beams without a staff symbol.

* Generic element property setting:

        \outputproperty #predicate #'symbol = #value

Will set the element property symbol to value, for any elements that
return true for PREDICATE.  This allows you to virtually tweak *ANY*
property of the output. Example in input/test/generic-output-property.ly

1.3.26
======

* lilypond as as2ly: --help and --version to stdout.  Regular identify 
  to stderr.  This fixes help2man's manpage generation.

* configure: substitute full path for perl and guile in scripts.

* Added ascii slur and volta.  There seems to be a Lily bug in volta placement.

* Bugfix: default font now user settable

* as2text: handle plain ascii font, read from stdin, you can now do:

  echo "\time 4/4; g''1 g2 g4. g8" | lilypond -f as -i init-as.fly - | as2text

1.3.25.hwn1
===========

* Bugfix: second half of broken ties now are displayed again.

* Bugfix: add clef to the support of 8 text in the G_8 clefs. Center
it horizontally on the clef.

* Added Tie_column spanner. Ties in tied chords now get proper directionsa.

* Bugfix: unbroken repeat barlines now work, eg. |:

* Added Request_iterator to make more flexible constructions possible.

1.3.25
======
* as2text: catch missing font/character errors, added default font, set text.

* New ascii fonts and glyphs: as5 as-numeral4 as-braces9

* Ascii output, minimal support:
  - AsciiScript Fonts: mf/*.af
  - Init files: ly/*-as.*ly 
  - AsciiScript translation to text: scripts/as2text.scm
  - input/test/as.fly input/test/as1.fly
  - Output support: lily/lily.scm
  - Try:
      lilypond -f as -i init-as.fly input/test/as.fly
      as2text as.as

1.3.24.hwn1
===========

* The horizontal part of ties will avoid collision with staff lines.

* Plugged memory leak: don't protect Atom function.

* Lookup cleanups. Made lots of functions static. Moved some code out
of Lookup.



1.3.24.hwn1
===========

* Bugfix: ly2dvi.py exits succesfully when encountering --help and
does not delete any of the file_ly*.tex.

* Added header and footer support in ly2dvi.py

1.3.24
======

* Added a ROADMAP file explaining the source directory layout.

* Minor tweak in the feta 6 and 9 numeral
 
* Moved files from lib/ to flower/

* Removed Note_head_side class.

* Updated the webpage to be a little more chatty. 

* Small Local_key_engraver optimization: only lookup timing engraver once.

* Fixed dashed slurs

* Rewrite of Slur code.  Be much more picky about slur shapes. We try
to offset the slur instead of bending it too much

* Look at stem directions for tie direction.

* Compound multimeasure rests. Put measures_i_ variable in an element
property.  Made the symbol a lot wider.

* Time signature small cleanups.

1.3.22.hwn2
===========

* Symbols opposite to stem (eg marcato) now get the proper glyph in up
version.

* Breathing marks now have a direction by default.

* Do set generic script properties.

* Also put tuplet brackets under notes.

* Score_element_info: only store origin of element, but not the path
to parent translators. Saves a little memory, and removes some complexity.


1.3.22.hwn1
===========

* Autobeaming in time sigs that don't have 1/4 beats fixed.

* (De)crescendi should now work. (Thanks Michael)

* Better error reporting for conflicting time signatures.

* Line_number_engraver: output locations of note head
definitions. Very handy when entering complicated scores.

* Rewrote multi measure rest support: now they are entered as spanners
(\commandspanrequest \start "rest"). RXXXX is an abbreviation for

  { \commandspanrequest \start "rest"
    SXXXX
    \commandspanrequest \stop "rest"
  }

* Removed support of percent style repetitions. 

* Put texts outside the staff.

1.3.21.mb1
==========
* Getopt bugfix: don't assert on certain errors.

* ly2dvi: Remove unnecessary space for the page headers.

* Bugfix convert-mudela

1.3.21.hwn1
===========

* Bugfix in lilypond-mode.el: eval-buffering now uses file name and
not buffer name.

* Scrapped tupletVisibility property. Now use tupletNumberVisibility,
tupletBracketVisibility, with Scheme value #t, #f or 'if-no-beam.
\property tupletInvisible will stop all tuplet spanner creation.

* Don't go berserk if tuplet spanner is on only one column.

* Use SCMs & Smobs for Molecules & atoms.  This uses less
scm_(un)protect_object () calls, so the output stage should be faster.

* Added \property tupletSpannerDuration, to make multiple tuplet signs
with one \times.

* Some programming Errors in spacing are now caught. Lily does not
hang when encountering degenerate springs.

* Allow beams to start and end over rests

1.3.19.hwn2
===========
* Fix disappearing clefs when clefs are not printed with a barline.

1.3.20.jcn2
==========

* SCM properties beamHeight and beamVerticalposition now use half-spaces:
  input/test/beam-control.fly
* Added \context Voice to .fly and .sly; the default \context Staff is almost
  never what you expect
* Fixed decision for .sly/.fly in lilypond-mode.

1.3.19.hwn1
==========

* Clean up font-metric hierarchy, use Adobe AFM code to parse AFM files.
Cleanup mf-to-table.py

* Fixed embarassing slur bug.

==========

* lilypond-mode.el: guess init file for lily-*-region, lily-mode-map bindings

1.3.18.uu2
==========

* lilypond-mode.el for emacs supersedes mudela-mode.el 

* Tuplet spanners don't collide with encompassing notes. 

* Gobbled Adobe parseAFM* code, for future use.

* Big 1999 to 2000 search/replace.

1.3.17.hwn2
===========

* Remove Paper_def calls in bezier-bow.cc

* Remove data members of Tuplet_spanner,  Volta_spanner

* hang_on_clef, property hangOnClef removed

* Bar::type_str_ mode into element property `glyph'. Use a Scheme
function to determine breaking behavior.

* Be strict about the difference between strings and symbols for conversion.

* Fixed bug that made 1st line offset to right fixed. Bugfix courtesy
Laurent Martelli.

* Partial French translation, courtesy Laurent Martelli.

* Small corrections in NL translation. 

1.3.17.hwn1
===========

* Added mensural note heads (noteHeadStyle = "mensural") Additionally,
we have a longa note head.  noteHeadStyle = "harmonic" is not
supported anymore. (for now, that is)  

* Reference manual update. Document \properties with examples

* fix mudela-book --help

* Use element properties for Text_item::text_str_, Clef_item::symbol_,
Key_item::c0_position_

* Clef_engraver general cleanup. Use alists (\property
supportedClefTypes, clefPitches) for clef types.

* Use progress_indication () for progress. Don't include <iostream.h> directly 
Don't include <string.h>, <math.h> from headers.
