Hi Folks,
I made an init file "persian.ly" with support for Persian accidentals and scale
signatures.
The only thing missing is correct glyphs for koron and sori. I include it below.
You don't want glyphs. You want strings, because we're not
expecting a music font, so the mechanism for glyphs won't work.
This can stay here:
% Define accidental symbols.
% Really need to have accidentals.koron and accidentals.sori
persianGlyphs = #`((-3/10 . "accidentals.mirroredflat")
(1/5 . "accidentals.sharp.slashslash.stem")
(0 . "accidentals.natural")
(1/2 . "accidentals.sharp")
(-1/2 . "accidentals.flat")
(-1/10 . "")
(-3/5 . "")
(-1 . "accidentals.flatflat")
( 1 . "accidentals.doublesharp")
)
Then add:
persianStrings = #`((-3/10 . "???")
(1/5 . "???")
...
)
where the ??? are replaced with the UTF-8 strings of the
symbols you want. Then in "\context" add
\override Accidental #'stencil = #ly:text-interface::print
\override Accidental #'text = #accidental-text
\override Accidental #'font-name = #"???"
\override Accidental #'font-size = #?
\override Accidental #'text = #(lambda (grob)
(cdr (assoc (ly:grob-property grob 'alteration)
persianStrings)))
\override Accidental #'X-extent = #(0 . 1)
\override Accidental #'Y-extent = #(-1 . 1)
and so on for KeySignature and whatever else you want to use
the new symbols. The font name is what Pango uses to find
the new font and you may need to adjust the font size. For
the best results use lookups for the X- and Y-extents as well.
Something I'm doing is causing a bug on another system, but
this works for me.
