Can you be more specific? It does not seem to me that lua uses pattern
matching (nor on multiple chunks). If you are talking about the lua
lexer... well, I do not want to implement a proper lexer. Here I was
just searching for a way to detect if a failing pattern have some
chance to match when data is appended to the input

Yes, I agree with you that it is quite arbitrary for the described
scenario. However, I am investigating on the possibility to use the
same format for data insertion/transfer/storage. So keep all in memory
could not be feasible. Splitting the chunks on specific token (e,g,
new line) could work, but I have some patterns that spawn across
multiple lines, so at least that ones must be handled in a special

If I have to write a C library, probably the quickest solution is just
to modify the lua pattern matching library in order to return a the
end position in case of failure. I think it should be enough.
