Kannan,
not readily.
The problem is that PEG parsers can potentially backtrack all the way to the beginning of the input.
Therefore you’d have to buffer the stream in its entirety which is probably not what you want.
However, if you have a grammar for streaming input you normally have some kind of “chunks” that form natural backtracking boundaries, i.e. you can ensure (through the grammar design) that the parser would never have to backtrack beyond a chunk boundary.
In these cases you could simply start buffering the stream at a chunk start and let parboiled run against the input with a parser that will only parse one single chunk.
Then, when you have successfully parsed a chunk, you clear the buffer and start the next chunk with a new parser instance.
Would something like that work in your case?
Cheers,
Mathias
