Hello,
I've just played around with vala for the first time tonight, and I find it
very intriguing! I've been previously using gob for most of my C coding, but
I think that I will try to move to vala as much as possible, as soon as I
feel comfortable enough with it.
In my efforts to of making sure that I can do simple constructs with the
language I tried to read a file line by line. The problem is that fgets() is
mapped quite shallowly as follows:
public weak string gets (string s, int size);
Thus I need to make sure that s has the requested size before calling gets.
This is what I eventually came up with:
using GLib;
int main(string[] args) {
if (args.length < 2) {
stderr.printf("Need name of file!\n");
return -1;
}
var f = FileStream.open(args[1],"r");
int n = 1000;
string s = " ".ndup(n);
int line = 0;
while(true) {
f.gets(s, n);
if (f.eof())
break;
stdout.printf("Line %d: %s", line++, s);
}
return 0;
}
Is there a more elegant way than by using ndup(n)?
Thanks again!
Dov
