Re: A couple of questions about Edition Engraver

[Stefano Troncaro]

I completely missed development1.ly, that is great! The way the proc is managed is particularly useful. It seemed to me that all the ingredients for a convenience function are already there.

I am undecided on what the best interface for it would be though, since as Urs already mentioned there are trade-offs with each possibility. I too think that a discussion should be had about that, to see what use-cases and needs arise. How do you usually do that here? Do you make a new thread asking users for feedback?

Thank you all for your responses to my original post, and for the
ensuing discussion which I am following with great interest.  I shall
not reply to each response individually, mainly because I have little
to offer that would be constructive: I made my original post because it
was my view as a complete "newbie" to Edition Engraver, and sometimes
comments from a naive user can be useful.

To pick out a few points:

Perhaps not, looking at it from a functional point of view.  But
structurally (i.e. from the human editor's point of view) it is very
similar to something we are used to, such as:

\book {
  \score {
    \new StaffGroup <<
      \new GrandStaff <<
        \new Staff { \violinOne }
        \new Staff { \violinTwo }
      >>
      \new Staff { \cello }
    >>
    \layout {
    }
    \midi { }
  }
}

and I reckon that even I could knock some Scheme together which would
convert it back to the standard basic form where each line starts with
\editionMod.  But as a stand-alone program, which is all I could
manage, that would not be practical.

That might be useful for an expert but, for me, it would not help in
finding my way around what might be quite a big file.

Great!  My purpose in making the original suggestion was to suggest the
kind of thing that might be useful.
