About Files

[_amitvyawahare_]

Hello,

My name is Amit. I am scripting InDesign CS3 using JavaScript in the OS X environment.
I am opening a file using app.open(File("~/Desktop/minu/Amit-TOC.indd"));

If such file is not present my script will come up with an error.
What i want is if such file is not present. Program should automatically quit without giving any error.

Hi Amit,

Use try...catch, like this:

try{
app.open(File("~/Desktop/minu/Amit-TOC.indd"));
}
catch(e){}

There are other ways to do it--you could check for the existence of the file first. Take a look at the File and Folder reference in the JavaScript Tools Guide.

Thanks,

Ole

Hi Amit,
Ole is right.
In my humble opinion, it's a weird project to close your program if the file is not found. Don't you want to keep working on indesign afterall ?
try/catch is a intersting technique to get info when you face a boring bug. But for that simple instruction,you can choose to do that :
var myfile = File("~/Desktop/minu/Amit-TOC.indd");
if(myfile.exists==true)
{
app.open(myfile);
}
/* you may not want to be warned for the non presence of the file
else
{
alert("Sorry, the file may have been displaced or removed !")
// Or better
// File.openDialog("Pick a file please...");
}
*/
