Re: [Vala] Is this a bug or a feature?

Hello,

	
Attention, the function feof (in C) should not be used to check the end of a file: http://c-faq.com/stdio/feof.html

The correct code:

[indent=2]

init
  var f = FileStream.open("./main.gs","r")
  var a = new array of char[2048]
  while (f.gets(a) != null)
    a[a.length - 1] = 0         /*make it null-terminated*/

    var            /*caste array-of-char to a string*/
    print "%s", ONELINE
