Re: Wrapped DataInputStream API?

[Jonatan Liljedahl <lijon kymatica com>]

This works in seed:

GLib=imports.gi.GLib;
GLib.file_get_contents("COPYING",x={});
lines = x.contents.split("\n");

Then you can iterate over the lines as usual:

lines.forEach(function(line) {
  print(line);
});

or

for(var i=0;i<lines.length;i++) {
  var line = lines[i];
  print(line);
}
