You can use Javascript to read text files, you can also use Javascript to do error handling.
So its possible to use Javascript to Try reading a file, and determine if the file is available (exists and is readable as text) by checking for an error.
Here is a quick script that will tell you if a Text file exist, and if its Empty or Not.
=========================================
function main()
{
var state; // State or 0 = good txt, 1 = Empty, 2 = Read Error
var txt;
try {
txt = read(arguments[0]);
state = 0;
}
catch(err) {
// ERROR: unreadable file, or file doesn't exist
txt = err.message;
state = 2;
}
if (txt == ""){
// text file exists but is empty
state = 1;
}
return [txt,state];
}
=========================================
@Michel how do we format code again.. its pretty script still installed?
