Re: tiny function

[Jeffery Shivers]

Hi Gabriel-Marie,

Could you describe in context what you are trying to achieve? Are you meaning to apply *stanza* number, rather than instrument names? Have a look at:

In my music script I want to use this:

\new Lyrics \with { instrumentName = "1." shortInstrumentName = "1." }

However, I would like to make a function out of it.  I'm looking at this page:
http://lilypond.org/doc/v2.18/Documentation/learning/saving-typing-with-variables-and-functions

and this is what I have come up with, but I know this isn't right.  Can someone correct this for me?
Basically, I want to do this:
\new Lyrics \verseNumber #1

and have it create this: 
\new Lyrics \with { instrumentName = "1." shortInstrumentName = "1." }

verseNumber = #(define-music-function(parser location whatnumber)( number?) #{  \with { instrumentName = #whatnumber "." shortInstrumentName = #whatnumber "." } #}
