Firstly, Thanks for this answer. You understand exactly my problem

I need some precisions about patterns and include:

include = 'text.tex'; i understand this one but the next are not very  
clear for me

  include = '$self';

include = '$base';

Perhaps I need to wait for TM 2 !

Questions about Beamer

1) In text.tex.latex we have : firstLineMatch = '^\\documentclass(?!.* 
\{beamer\})';

and in 'text.tex.latex.beamer : firstLineMatch = '^\\documentclass(\ 
[.*\])?\{beamer\}';

I'm not sure that's a good way because i don't use listings (pb with  
utf8) and I prefer pgf/tikz to pstricks.
I would like to know if it's possible to enable or disable some  
parts. I'm not sure but I think that's a big and long grammar is not  
good for the speed to match a long text. That is why , I made a  
remark about "listings" because it's not "pure" latex.

There is now an excellent way for the preferences with a panel, we  
can imagine a panel for the grammar package to add :
beamer, memoir, xcolor, listings, pstricks, tikz, amsmath etc...  and  
for the author : calc ifthen etex multido

Or a file in the preferences

for text.tex.latex

I've make somme additions :

{name = 'meta.preamble.latex';
contentName = 'support.class.latex';
begin = '((\\)(?:usepackage|documentclass|RequirePackage| 
usetikzlibrary))(?:(\[)([^\]]*)(\]))?(\{)';

and some modifications

		{name = 'constant.numeric.math.latex';
		match = '((\+|-)?)(([0-9]*[\.][0-9]+)|[0-9]+)';

because There is constant.numeric.math.tex and no  
onstant.numeric.math.latex and i want the sign + or - in the same  
color !

for text.tex

With keyword.control.tex, I've a problem with some terms like  
\if at tkz@visible or  \ifTKZ at tkzInit@NO . The symbol @ is a problem and  
in a package author there a lot of terms with @.

I add name = 'keyword.operator.tex'

with begingroup, endgroup, global def edef xdef gdef expandafter  
newbox newdimen newcount advance multiply divide etc...

but i'm not sure like keyword.control.tex ( with if else fi) that's  
necessary to a classic user of TeX.

When you include text.tex in text.tex.latex, it's not a good thing.  
there are good package to avoid the use of if etc...
for example ifthen

A latex user must use \ifthenelse  \newboolean \setboolean \isodd  
\whiledo \equal \lengthtest all these macros are in Latex and not in  
tex.

Important keywords in LaTex are newcommand, renewcommand, newcounter,  
setcounter, newlength, setlength, addtolength and some keywords tex  
are also necessary : advance multiply divide etc...

  I'm sorry because a lot of ideas are not in a good order.
