Thanks guys, it's beginning to make a little more sense now.
My script is here:
%%%%%%%%%%%%%%%%%%%%%%
\include "lilyjazz.ily"
\score {
\new Staff {
\jazzOn
c'4 c' \tuplet 3/2 { d'8-- es'-- e'-- } g'4 ~ |
g'4 r r8 f'-^ \noBeam es' c'-> \bar "|."
}
}
\version "2.20.0" % necessary for upgrading to future LilyPond versions.
%%%%%%%%%%%%%%%%%%%%%%%
I've downloaded all the files which Jacques shows in the /otf directory (didn't bother with the svg and woff files since i'm only interested in pdf output at this point ... am i assuming correctly?). Also put lilyjazz.ily, lilyjazz-chord, and lilyjazz-text in the same directory, but on compiling the above script, the result is the same result: "error: cannot find file: lilyjazz.ily.
I can think of two possible issues:
1) Do the .ily files have to go in a specific directory?
2) I copied and pasted the .ily files into separate text files (couldn't see any way to download or install them directly from GitHub) and saved those in the /otf directory ... are the .ily files something more than just text?
Anyway, thanks for your help so far.
Jeff
PS I imply from Robin's suggestion that spaces are characters ... are we also case sensitive?
