Re: libseed-list trying to read a gio stream

[Jonatan Liljedahl <lijon kymatica com>]

Ah, I just found the get_contents() and simple_read() extensions. But I 
would like to understand this (in Gio.simple_read):

  var fstream = file.read();
  var dstream = new Gio.DataInputStream.c_new(fstream); //<-- here
  var line = dstream.read_until("", 0);

why the need for creating a DataInputStream from the FileInputStream, 
and what about the use of both new operator and c_new() method?

Thanks for the pointer on taking a look in the tests tree, will do that!

BTW, are extension .js modules automatically merged when importing a C 
or gi module? If I have a seed module in an .so and a .js with the same 
name, will both be loaded by imports.<name>?
