Hi,
I'm trying to create a script to automate certain things (setting
instrument name, default clef, transposition) based on a custom
property 'instrument' that is set when creating a new staff. I'm
having trouble retrieving that property when generating the music for
that staff. Using \applyContext or make-apply-context always results
in a warning:
warning: skipping zero-duration score
I'm totally new to scripting and Scheme, so I'm at a bit of a loss.
Could anybody shed their light on this?
I am sure that it would be possible to figure out a solution based on
your initial thoughts, but here is an alternative that I have used.
\version "2.24.4"
\layout {
indent = 3\cm
\context {
\Staff
\name "ClarinetBflat"
\alias Staff
instrumentName = "Clarinet in B♭"
shortInstrumentName = "Cl."
\clef "treble"
}
\inherit-acceptability ClarinetBflat Staff
}
\midi {
\context {
\Staff
\name "ClarinetBflat"
instrumentTransposition = bes
}
\inherit-acceptability ClarinetBflat Staff
}
\score {
\new ClarinetBflat { c'4 d' e' f' }
\layout {}
\midi {}
}
You could perhaps automate this further by writing scheme functions to
return the contexts, looking up data in your table of instrument properties.
layoutcxt = #(define-scheme-function (instrument) (symbol?)
#{
\context {
\Staff
\name #(symbol->string instrument)
\alias Staff
...
}
#}
)
\layout {
\layoutcxt #'ClarinetBflat
\inherit-acceptability ClarinetBflat Staff
}
