[JW Lua] Updating expression categories

[Jan Angermüller]

FCString:ReplaceCategoryFonts() is what you need.
This changes "Finale Maestro" dynamics to "Bravura".

local catnumber=1
local c=finale.FCCategoryDef()
c:Load(catnumber)

local f=finale.FCFontInfo()
c:GetMusicFontInfo(f)
f.Name="Bravura"
c:SetMusicFontInfo(f)
c:Save()

local te=finale.FCTextExpressionDefs()
te:LoadAll()
local t
for t in each(te) do
     if t.CategoryID==catnumber then
         local tstr=t:CreateTextString()
         if tstr then
tstr:ReplaceCategoryFonts(c,finale.CATEGORYMODE_MUSIC,true)
--tstr:ReplaceCategoryFonts(c,finale.CATEGORYMODE_TEXT,true)
--tstr:ReplaceCategoryFonts(c,finale.CATEGORYMODE_NUMBER,true)
             t:SaveTextString(tstr)
         end
     end
end
