release: 1.5.37

[lilypond.git] / ChangeLog

2002-03-03  Han-Wen  <hanwen@cs.uu.nl>

        * VERSION: 1.5.37 released

        * lily/key-signature-interface.cc (brew_molecule): rename from key_item
        left-align molecule.
        
        * lily/break-align-interface.cc (do_alignment): completely
        rewritten. Now it does not use Align_interface anymore, but a
        separate routine. Like StaffSpacing, it reads space-alist from the
        breakable grobs.  This allows you to set spacing using
        
        \property Staff.Clef \override #'space-alist = '(....stuff....)  
 
        * lily/bar-line.cc, lily/include/bar-line.hh: change name from Bar
        to Bar_line. Move files around as well.

        * lily/time-signature.cc (time_signature): left align time signatures. 

        * mf/feta-timesig.mf: Remove padding from C-style time signatures.
        Corrections of the glyph shape C. Comments added.

2002-03-02  Han-Wen  <hanwen@cs.uu.nl>

        * lily/spacing-spanner.cc: move from third-try.cc; rename
        Third_spacing_spanner to Spacing_spanner.

        * lily/staff-spacing.cc (get_spacing_params): redo prefatory
        spacing stuff. Much cleaner now, and we prepare for neat spacing
        tricks around bar lines and such.

        * lily/third-try.cc (prune_loose_colunms): bugfix. Don't init
        variables with themselves. (Ouch.)

        * lily/span-bar.cc (brew_molecule): don't try to span bars that
        overlap.
