Some questions about luatex

Some questions about luatex

[luigi scarso]

hi some questions about luatex
(www.luatex.org)
1) will be possible some code like
\luatry{%
...tex code}
\luaexcept{
..tex code}
2) will be possible to embedding some other language ie Python (of
course, reading the C source) ?

Thanks in advance
luigi

i'm not sure what you mean here 

\somelua{ lua code that may or may not give back tex input } 

if you mean that we can use lua for pretty printing, then the answer is yes, in my mkiv code there is already a lua based pretty printing framework

Guess at what you want: maybe, but not right away. The \luatry
would have to save quite a bit of state information for this
to be useful, which is not feasible on short notice (imagine
having to save some 400+ globals and hooking into a few dozen
data structure operations)

If you want to change the sources yourself, then yes. Otherwise
no. If luatex were to allow this without recompile, nobody could
rely on a stable platform for interchange of documents.
