Hi All! can you tell me a JS script that can take me in random files and copy them in a specific file?
Example: I have files that are called logo.1, logo.2, logo.3, logo.4 etc ... the script randomly takes one of these files and copies it as logo.ans

Thank you
Thomas Bampi

The logon.js will already do that for you. Just name your .asc files random1.asc, random2.asc and so on. Instaying with the 8.3 standard, you can make 99 of them.

This question is best asked in one of the Synchronet Programming related message areas, but here's a short example in JS:

file_copy("logo." + random(4), "logo.ans");

There's an even better example in exec/logon.js (search for "random").

I was hoping for an algorithm that would pull a random line out of a text file, but then I broke up my text file into dozens of files with one line each.

Pulling a random line is pretty easy too:

var f = new File(fname);
if(!f.open("r")) {
alert("Error opening " + fname);
exit();
}

var list = f.readAll();
f.close();
var i = random(list.length);

var line = list[i]; // line is now a randomly chosen line from the file

var f = new File('lines');
f.open('r');
var lines = f.readAll();
f.close();
var line = lines[Math.floor(Math.random() * lines.length)];

Something like that ort to work.

Easy for you! :)

Thanks a lot -- this will clean up my install greatly and let me add lines much more easily than creating a new file each time I add a line.
