[Boost-users] getline from boost::iostream::filtering_streambuf

I want to read line by line from a gzipped document.

I first do:

std::ifstream file(fileName.c_str());
boost::iostreams::filtering_streambuf<boost::iostreams::input> in;
in.push(boost::iostreams::gzip_decompressor());
in.push(documentFile);

However, then the obvious:

string line;
while(std::getline(in, line)) { ... }

does not compile.

Is there really no getline for filtering_streambuf?

If not, what is the best way to write one?

I tried reading character by character using boost::iostream::get(in) 
but that looks terribly inefficient to me, and is not nice code.

Thanks for your help,

Holger
