yes, you made a correct synthesis of my ideas.

But why conditionally include grammars ??

I'm not a specialist of script, regex etc.... but in a first time
it's possible to build some grammars like

text.tex
text.tex.math
text.tex.beamer
text.tex.listings
text.tex.tikz etc....

And to finish the text.tex.latex by some include like

include = 'text.tex.listings'; ?

Each user can modify the list of the package grammars !


Perhaps I'm wrong ...


About listings, why make a grammar to this package ?

There is a way to turn around the difficulties.

\lstinputlisting[key=value list]{hfile name}

example :

\usepackage{listings}
\lstset{language=C}
...
\begin{document}
\lstinputlisting{main.c}
\end{document}

or you can make that

\lstinputlisting[first=10,last=50]{main.c}

It is the only way for me to use listings because I'm french (I need  
only to
include  latex code but with accents) and it's impossible
to use listings with utf8  actually, so I need to save file with  
latin1 encoding
and to use two encodings latin1 and utf8 is the same file ! (very bad)

I suppose that you need to include java code or python code but there  
are scopes
  to verify the syntax of these languages. So why waste time with a  
difficult grammar and not
  include the sources of codes.
