Is there a way with JSX to save text to a file?

[Guest]

I'm looking for a way to save JSX script-generated log entries to a text file, not just from Photoshop but also from InDesign and Illustrator as well. There are discussions elsewhere about using the DataObject class, but those discussions are from a few years ago, there is nothing about them (that I could find) in the CS6 documentation, and nothing comes up in EST's auto-complete. Any ideas? Thanks

Something like this?

logInfo((new Date).toString());
logInfo("This is the first message");
logInfo("This is the second message");
 
function logInfo(Txt){
var file = new File(Folder.desktop + "/ScriptLog.txt");
file.open("e", "TEXT", "????");
file.seek(0,2);
$.os.search(/windows/i)  != -1 ? file.lineFeed = 'windows'  : file.lineFeed = 'macintosh';
file.writeln(Txt);
file.close();
};

That would do it. Thanks so much. Out of curiosity, is that anywhere in Adobe docucmentation or is this pure Javascript?

You can find this information in the Object Model Viewer under Help in ExtendScript Toolkit

Look at Core JavaScript Classes and select File

Hope it helps.

There is documentation .pdf called JavaScript Tools Guide, also available under Help menu

right now this code saves the text file to the desktop.

what if we wanted to save it to:

C:\MyFolder\MyFiles

instead?

logInfo((new Date).toString());  
logInfo("This is the first message");  
logInfo("This is the second message");  
   
function logInfo(Txt){  
var file = new File(Folder.desktop + "/ScriptLog.txt");  
file.open("e", "TEXT", "????");  
file.seek(0,2);  
$.os.search(/windows/i)  != -1 ? file.lineFeed = 'windows'  : file.lineFeed = 'macintosh';  
file.writeln(Txt);  
file.close();  
};

If 'MyFolder' already exists, replace input of new File(), to "/c/MyFolder/ScriptLog.txt"

What are the params ("e", "TEXT", "????") in file.open for?

[Stephen Marsh]

"e" is for edit mode:
