String tokenizer?

[bfry5282]

Anybody got a routine to tokenize a string on a separator character and return an array of string tokens? TIA

Try this out... it should do the trick.

function Tokenize(vString) {
    
    var aString = new Array(vString.length);
    for (i=0; i < vString.length; i++) {
        aString[i] = vString.charAt(i);
    }
    
    return aString;
}

Thanks for the routine.

I also found the string split function.

Great support!

Just for the thread's reference... here's the split function for the String object.

Just to make sure anyone doing a search gets a complete reply...

This code fragment shows how to split an array of strings that is delineated by comma's. You can specify any delineator you want by changing the "," in MyLine.split().



var vMyLine = "This,is,a,test";
var vTest = vMyLine.split(",")

// vTest[0] should be: This
// vTest[1] should be: is
// vTest[2] should be: a
// etc

var i;
for (i=0; i < vTest.length; i++){ // verify
debugPrintln("vTest[" + i + "] = " + vTest[i]);
}

sample efs, obtaining file values

Here is a code snippet that I have which obtain file values. It is set up to parse the text values to numbers, but that step can be taken out. This is just an excerpt from some of my code and this efs does not run, although it would not take much to make it work.

 var ff =0;

function preMain() {

    ff = getDef2();//gets flag variablesinitializes flags 

function main(){


}

function getDef2 (){//flag data
    
    var fl2 = new File("Buy Code Flags.txt");
    if (fl2.exists){
        fl2.open("rt+");
        var d=fl2.readln();
        fl2.close();
        tTime = nTime();//tTime [0] = milliseconds, [1] = h:m:s, [2] = MM-DD-YYYY, [3] = h, [4] = m, [5] = s, [6] = Total s.
        if (d != null ){var dd=d.split(",");}
        else{
            var dd = Initialize_1X_Array(40);//sets all of them to zero
            return;
        }
        
    }
    else {var dd = Initialize_1X_Array(40);}//if file does not exist, sets all of them to zero
    var i;
    for (i=0;i<40; i++){dd[i] =parseFloat(dd[i]);}//converts text to numbers
    return dd;
} 

If you want to mix numbers and text in the same file, here is what I do (from a separate routine)...

    for (i=0;i<100; i++){
        debugPrintln("dd["+i+"] = "+dd[i]);
        if (i == 6 || i == 44){newArray[i] = dd[i];i++;}//these are the two text fields
        newArray[i] = parseFloat(dd[i]); 

note that array values 6 and 44 are text, so I do not parse.
