i am trying to save a string with more than 2000 character using javascript. inside javascript i can address and manipulate strings with a lenght of more than 90000 characters. but it is impossible to store the large string.

- the messagewindow outputs only 2000 characters

- the file i save contains 90000 characters, but the last 98000 are empty.

- max crashes, when i generate a string with more than 100000 characters

here is my example script (just send a bang):

____________________________________________________

    this.thePatcherPath = this.patcher.filepath;

        theOutString = theOutString + "I";

        theOutString = theOutString + "B";

    thePath = this.thePatcherPath + "/" + "test.txt"

    this.writeFile( thePath, theOutString );

function writeFile( whichFilePath, whichString ){

    post( "n" + " last : " + whichString.charAt( 90000 ) + "n" );

    post( "n" + " string : " + whichString + "n");

    post( "n" + " length : " + whichString.length + "n");

    f = new File( whichFilePath, "readwrite", []);

I remember encountering the length limit for writestring (and perhaps 

for readline as-well, can't remember any more), and my workaround was 

to write the string byte-by-byte - using writebytes/writechar.

don't know about maximum string length, but if you need humongous 

amounts of bytes, perhaps you could use jit.matrix?

just split the string into slices before saving ....

    theDivisions = whichString.length / theMaxChars;

        f.position = ( i ) * theMaxChars;;

        theString = whichString.slice(i*theMaxChars, (i+1)*theMaxChars);

        f.writestring( theString );

found a solution !

its a bit laborious ...

function writeFile( whichFilePath, whichString ){
	f = new File( whichFilePath, "readwrite", []); 
	f.open( whichFilePath );

	theMaxChars = 1000;
	theDivisions = whichString.length / theMaxChars;

	for ( var i=0; i
		f.position = ( i  ) * theMaxChars;;
		theString = whichString.slice(i*theMaxChars, (i+1)*theMaxChars);
		f.writestring( theString );
	}
	f.eof = whichString.length;
	f.close()
}


store more than 2000 characters @ external file
