In trying to implement the idea of a tag set, I came up with the following:
%%%%%%%%%%%%%
\version "2.19.53"
gender = #'male % manually set to male, female, neutral
#(define test 0)
heshe = \lyricmode {
\tag #'male { he #(set! test 1) }
\tag #'female { she #(if (eqv? test 1) (error "more then one
pronoun") (set! test 1)) }
\tag #'neutral { he/she #(if (eqv? test 1) (error "more then one
pronoun") (set! test 1)) }
#(set! test 0)
}
hisher = \lyricmode {
\tag #'male { his #(set! test 1) }
\tag #'female { her #(if (eqv? test 1) (error "more then one
pronoun") (set! test 1)) }
\tag #'neutral { his/her #(if (eqv? test 1) (error "more then one
pronoun") (set! test 1)) }
#(set! test 0)
}
global = { \key c \major }
verse = \lyricmode {
Filled with the Spir -- it, by \hisher earth -- ly la -- bours,
Brought to your peo -- ple heal -- ing and com -- pas -- sion;
Rais -- ing the fal -- len, re -- con -- cil -- ing sin -- ners,
Glad -- ly \heshe served them.
}
music = {
c' c' c' c' c' c' c' c' c' c' c'
c' c' c' c' c' c' c' c' c' c' c'
c' c' c' c' c' c' c' c' c' c' c'
c' c' c' c' c'
}
\new Staff \keepWithTag \gender
<<
\new Voice = "mel" { \global \music }
\new Lyrics \lyricsto "mel" { \verse }
>>
%%%%%%%%%%
This, however, raises errors when it's not supposed to (i.e. when
\keepWithTag \gender is present). GUILE is indicating that something is
wrong with the scheme, but I don't know what, as the applicable scheme
runs as expected when entered by itself in the guile interpreter in the
LilyPond app. Is something like this even possible, and if so what am I
doing wrong?
