And @David Kastrup : thank you very much for telling me how to achieve the same name for environment and command !

I found the problem : it came from @currenv, that is in fact @currenvir. After last modifications, I think lyluatex should work as a drop-in replacement for lilypond-book, while keeping backward compatibility for those who already used lyluatex.

Please feel free to test and report bugs !

Just tried that, and it doesn’t work :

address@hidden
\protected\def\lilypond{\def\raddress@hidden
  address@hidden@currenv address@hidden
  \else \expandafter \lily \fi}

I think it has something to do with \expandafter, but I don’t know TeX enough to be sure…

Neither are called lilypond.  It's not particularly great, but there are
examples for the sharing of command and environment.  Basically you
check whether @currenvir is set to LilyPond.  As long as you don't
_nest_ those constructs...

The environment is defined as `ly`, but there is a `lilypond` alias. So `\begin{lilypond}` just works.

Basically:

\newenvironment{lilypond}
{...}
{...}

\newcommand{\lilypondcommand}{...}

address@hidden
\protected\def\lilypond{\def\raddress@hidden
  address@hidden@currenv address@hidden
   \else \expandafter \lilypondcommand \fi}

Ugly, sure.  But I think LilyPond upstream would be sympathetic to
making command and environment named differently in the long run.

 

I'm going to try it just now.

I don’t know enough about (La?)TeX internals to understand the code above but if you redefined the command \lilypond, would things like the following still be possible?

\newenvironment{dly}{
\center
\ly
\language "deutsch"

\paper {
        ##(define fonts
                (set-global-fonts
                ##:music "cadence"
                ##:brace "cadence"
                ##:roman "Vollkorn"
                ##:factor (/ staff-height pt 20)))
}

\layout {
        % some other general things
}

% some includes and function definitions
}{\endly\endcenter}

 

As you are using `\ly`, as soon as I don't modify it, it'll work.
