So, I've been working with a new user to get the engines up and running
for him and came across an unexpected problem that wasn't related to the
engines:
In his preamble he had:
\usepackage{gregoriotex}
\usepackage{luatextra}
This caused problems. In particular \ifgreluatex wasn't recognized as a
properly defined control sequence. Reverse the order of the package
inclusion and things work fine. That tells me that one of two things is
happening:
1) gregoriotex is dependent on luatextra and if it finds it hasn't been
loaded can't define \ifgreluatex properly.
2) gregoriotex and luatextra conflict with each other when it comes to
defining some functions which somehow leads to \ifgreluatex being undefined.
My gut says its more likely the first than the second, given the error I
(and the new user) were seeing (and the fact that I can imagine the path
that leads to the error in that case but not the other). This can
easily be resolved by placing \RequiresPackage{luatextra} into
gregoriotex near the beginning of the file. In this fashion it will be
automatic that luatextra will be opened before gregoriotex begins
defining functions.
Opinions? Am I missing anything?
