Re: Snippet variations

For those not familiar with lyluatex, the way I'm using it works as follows:

1) Inside a the TeX file there is a pointer to the lilypond source file 
of the snippet I want to include.

2) When LuaTeX processes the document, it looks at the file indicated by 
the pointer and looks to see if there existing, up-to-date images of 
that snippet.

3) If LuaTeX cannot find existing, up-to-date images, then it runs 
lilypond on the the source.

4) The up-to-date images are then included in the document in the 
location where the file pointer was specified.

In a sense, both of these conditions are true.  Each snippet has its own 
LY file and they are all being included in a master document, it's just 
that the master document is a TeX document, not a LY one.

Further, I need to use both versions of the snippet in the same 
document.  As a result, I cannot just change the LY source when I want 
one or the other, I have to be able to get both out at the same time.

Adapting what you suggested, then, it seems that I might be able to do 
the following:

1) have the snippet source which doesn't contain the \aster definition
2) have two different include files, one with \aster defined to insert 
the `*`, the other with it defined to do nothing
3) have two "top-level" files which include one of the \aster definition 
files and the snippet source
4) in the master document, point to the "top-level" file which 
corresponds to the version of the snippet which I want in that location


That seems like a fairly reasonable solution, unless some one out there 
has a better one.
