Hello all,

In the snippet, below, the font-name override kills the \italic as set in the \header.
Is there any way to avoid that [without having to hack the title into two separate functions/parameters]?

Thanks,
Kieren.

%%%  SNIPPET BEGINS
\version "2.19.59"

\paper {
  bookTitleMarkup = ##f
  scoreTitleMarkup = \markup {
    \override #'(font-name . "Minion Pro")
    \fromproperty #'header:title
  }
}

\header {
  title = \markup { "SATB chorus" \italic "a cappella" }
}

The reason it breaks the \italic is because you don't tell LilyPond that there _is_ an italic variant when all you do is override the font-name like that. 

The better way would be to add a text font to the "fonts" tree because it looks for the four standard family members (regular, italic, bold, and bold-italic). I think the scheme function is "add-text-fonts". You can find how it's used in the file [LILYDIR]/scm/font.scm.

With the font family added (let's say it's the 'minion family), you the change to it with

\markup {

  \override #'(font-family . 'minion)

  ...

}

And if Pangolin found the italic variant, you shouldn't need to do anything else other than \italic like normal.

Oh, boy. My phone's auto-correct... That should read "Pango".

Anyway, I realized I didn't give you a very complete (or correct) solution. So, let's try again. The \paper block should look like this (and this should be below any #(set-global-staff-size ...) because that resets the "fonts" variable and you need to add to it):

%%%%%%%%%%%%%

\paper {

  #(add-pango-fonts fonts 'minion "Minion Pro" (/ staff-height pt 20))

  bookTitleMarkup = ##f

  scoreTitleMarkup = \markup {

    \override #'(font-family . 'minion)

    \fromproperty #'header:title
  }

}

%%%%%%%%%%%%%

Now, the font choice should propagate through to the \italic command.

HTH,

Abraham
