[antlr-interest] How to make a restartable parser ?

[Vincent De Groote]

Hello,

Is there a way to use the parser generated by ANTLR as a "restartable"
parser ?

The problem I try to solve is:
The text I need to parse is a text fragment.  It will be followed by other
text fragments, until end of file.
I do not want to accumulate fragments, because the input may be very big.
I suppose I could generate a lexer with a special token 'restart'.  When
such a token is received by the parser, the parser should save its state,
and return with a specific result code.  When I receive more text, the
parser should restart with the state saved before.

Is there a way to handle this model with ANTLR ?

Thanks for your replies
