Global colour substitution for specific characters in lyrics

[Witold Uchman]

Hello!

I am looking for a way to simplify input in a book of psalms, namely to be able to simply put an * in lyrics and make the character in red.

I tried with #(add-text-replacements!, but it only performs simple character substitution, and I am afraid I am not fluent enough in lilypond to create a function...

\language "deutsch"

transpozycja=c'
akordy={\chordmode{
}}
melodia={
    \key d \minor
        f8 g[ a] a\breve b8 a g a4\bar "|"
        a\breve g8 f g[ a] g[( f e] d4)\bar "|."
}
tekst={\lyricmode{
    Bo -- że, "mój Boże," szu -- kam Cie -- \markup{\concat{"bie " \with-color #(rgb-color 0.894 0.207 0.172) *}}
    "i pragnie Ciebie" mo -- ja du -- sza._*
}}

\score { \transpose c' \transpozycja
    <<
      \chords { \akordy }
      \relative c' { \cadenzaOn \autoBeamOff \melodia }
      \addlyrics { \set stanza = "1." \tekst }
    >>
}

\layout {
    \context { \Lyrics
               \override LyricText.self-alignment-X = #-1
               \override StanzaNumber.font-series = #'medium
               \override StanzaNumber.color = #(rgb-color 0.894 0.207 0.172)
               \override StanzaNumber.font-size = #+1 }
    \context { \ChordNames \germanChords chordNameLowercaseMinor = ##t }
    \context { \Lyrics \consists "Bar_engraver"
                \consists "Separating_line_group_engraver"
                \hide BarLine }
}


Thanks for your help!
