So how can i achieve what i want?
Which is, in pseudocode:
newStaffContext =
#(define-scheme-function (parser location name)(string?)
#{
\layout {
\context {
\Staff
\name #(concat name "Staff")
\alias "Staff"
instrumentName = #name
}
}
#})
\newStaffContext "Test"
\newStaffContext "Foo"
etc... (i hope it's clear what i want)
thanks,
Janek
