Need to remove some characters in the text in active document

[rarur97798982]

Hi all,

Here I had made a script to write equations with superscript.

The input maybe

a^{2}+b^{2}=c^{2}

The Required output is

a²+b²=c²

The script I made is.

if(documents.length >0){  //if document is open      
    if(app.activeDocument.selection[0]){  //if a line is selected  
        var supBPosition=[]; 
        var subBPosition=[];
        var doc = app.activeDocument;  //getting the active document
        var line = doc.pathItems[0];  //getting path items from the active document  
        var firstPoint = line.pathPoints[0].anchor; // [x, y]
        var lastPoint = line.pathPoints[line.pathPoints.length - 1].anchor; // [x, y]        
        var eqValues = (prompt("Enter something ", "", "")); //getting the values to write
        var eqValuesCopy=eqValues;
        var startCharacterSize=0;
        var ys=[]; 
        var ns=[];
        var nsDummy=[];
        var yFlag=0; 
        var nFlag=0;
        var plotGraph=1;
        getPositions();   
        var finalContent=eqValues;
        if(eqValues.indexOf("^")>0){                         
            plotGraph= doc.textFrames.add();  //adding text
            plotGraph.textRange.characterAttributes.size = 8;  //character size for text
            plotGraph.textRange.characterAttributes.textFont = app.textFonts.getByName("Times-Roman"); //for changing the font to times-roman
            plotGraph.textRange.justification = Justification.CENTER;  //for aligning the content to center
            plotGraph.top = firstPoint[1];  //x coordinate for the new value
            plotGraph.left = firstPoint[0];  //y coordinate for the new value            
            plotGraph.contents=(finalContent);
            var t = doc.textFrames[0];  
            for(var m=0;m<=ns.length;m++){
                for(var plotGraphSup=ys;plotGraphSup<=ns;plotGraphSup++){  
                    thisChar = t.characters[plotGraphSup];  //writing base value               
                    thisChar.characterAttributes.baselineShift = +3;  //making superscript  
                    thisChar.characterAttributes.size = 6;  //adjusting size of superscript
                }                 
            }
        }
    }
    function getPositions(){    
        for(var i=0;i<eqValuesCopy.length;i++){
            if(eqValuesCopy=="{"){
                if(i!=0){
                    validBCheck=eqValuesCopy[i-1]+eqValuesCopy;
                    if(validBCheck!="/{"){
                        ys.push(i);
                    }
                }
            }
            ysLength=ys.length;
        }
        for(var i=0;i<eqValuesCopy.length;i++){
            nsLength=ns.length;
            if(nsLength<ysLength){
                if(eqValuesCopy=="{"){
                    var j=i;
                    while(j<eqValuesCopy.length){
                        j++;
                        if(eqValuesCopy=="}"){
                            ns[nsLength]=j;
                            break; 
                        }else if(eqValuesCopy=="{"){ 
                            nsLength++;
                        }else{ 
                        }
                    }  
                    i=j;
                }
            }
        }
        for(var k=0;k<eqValuesCopy.length;k++){
            if(eqValuesCopy=="}"){
                var h=k;
                while(h<eqValuesCopy.length){
                    h++;
                    if(eqValuesCopy=="{"){
                        break;
                    }else if(eqValuesCopy=="}"){ 
                        nsDummy.push(h);
                        break;
                    }else{ 
                    }
                }
            }
        }
        nsDummy.reverse();
        for(var x=0;x<nsLength;x++){
            if(ns===undefined){
                ns=nsDummy;
            }
        }
    }
}

Also I am getting an error in line number "32".

for(var plotGraphSup=ys;plotGraphSup<=ns;plotGraphSup++){

should be:

for(var plotGraphSup=ys;plotGraphSup<ns;plotGraphSup++){

Bonjour,

Me too,

but anyway - try this (this is the same code as in your other thread)

var aSample = "a^{2}+b^{2}=c^{2}_{2}";
var aDoc = app.activeDocument;
var aTF = aDoc.textFrames.add();
aTF.position = [10, -2];
aTF.contents = aSample;
aTF.textRange.size = 8;
aTF.textRange.characterAttributes.textFont = app.textFonts.getByName("TimesNewRomanPSMT"); //depends on your Illu version and installed font
var res, idx;
var reg = /\^\{/g;
while (res = reg.exec(aTF.contents)) {
    idx = res.index;
    aTF.textRange.characters[idx].remove();
    aTF.textRange.characters[idx].remove();
    aTF.textRange.characters[idx].baselinePosition = FontBaselineOption.SUPERSCRIPT;
    aTF.textRange.characters[idx+1].remove();
}
var reg = /_\{/g;
while (res = reg.exec(aTF.contents)) {
    idx = res.index;
    aTF.textRange.characters[idx].remove();
    aTF.textRange.characters[idx].remove();
    aTF.textRange.characters[idx].baselinePosition = FontBaselineOption.SUBSCRIPT;
    aTF.textRange.characters[idx-1].tracking = -480; // TimesNewRomanPSMT
    aTF.textRange.characters[idx+1].remove();
}

Have fun

Hi pixxxel,

This works. But the problem comes when, the input is

a^{21}+b^{2}=c^{2}_{2}

Something like this. This is why I had used the loop to get the starting and ending position on superscript and subscript values.

[pixxxelschubser]

There is one rule for scripting and Grep (Regex):

The better/detailed and more the examples - the better the script/grep

How about the solution by renél80416020 in post #3 ? Should work with more than one sperscript/subscript digits.

Regards

Maybe I have a final solution for you - but you do not give feedback. In none of your four threads.
