Hi Phil,
you just need to remove the parens around 'theText'. Also inside (markup
...) everything is interpreted as a parameter for the function (macro or
whatever) 'markup' and evaluated as a scheme-expression for thet purpose.

#(define-markup-command (do-tilde layout props theText) (string?)
(interpret-markup layout props
(markup theText )
))

I want to create a function in scheme that will take a string argument
something like "san~t" and return a markup which will place the tilde
above the n. I know how to create the markup using markup functions like
combine and translate, but I want to make this easier by using a scheme
function. I'm struggling to work out how to take a string argument and
use it to return markup. My test function is:
#(define-markup-command (do-tilde layout props theText) (string?)
(interpret-markup layout props
(markup (theText) )
))
I call it with:
mel = \relative c'' { c4 }
lyr = \lyricmode { \markup { \do-tilde #"Testing" } }
<<
\new Voice = melody \mel
\new Lyrics \lyricsto melody \lyr
I get the error
In expression (theText):
LyricTest.ly:13:17: Wrong type to apply: "Testing"
Can anyone point out to me what I'm doing wrong (or how to do this
correctly?)
TIA
