Code to be evaluated! [016] Tabs Position! …

[Obi-wan Kenobi]

Hi All,

The deal is simple:

You select text with tabs and run the script below! You just need to enter the new font size!

The script seems to work! The position of the tabs is recalculated, depending on the new font size, here 16 pts => 8 pts!

… If I want to go back (no undo!): 8 pts => 16 pts and run the script again:

No idea to correct this!  Thanks for help! 

var w = new Window ('dialog {alignChildren: "top"}', 'New Tabs position! …');
 w.alignChildren = "right";
    var group1 = w.add ('group');
        group1.add ('statictext {text: "New Font Size:"}');
    var UIy = group1.add ("edittext", undefined, 0);
        UIy.characters = 5;
        UIy.minimumSize.width = 60;
        UIy.maximumSize.width = 60;
        UIy.active = true;
    var buttons = w.add ('group {alignment: "center"}');
        buttons.add ('button {text: "OK"}');
        buttons.add ('button {text: "Cancel"}');
    var group2 = w.add ('group');
        group2.add ('statictext {text: "(by Michel Allio, March 2017)"}');
if ( w.show () == 1 )  var y = Number (UIy.text);
else  exit();
app.doScript("main()", ScriptLanguage.javascript, undefined, UndoModes.ENTIRE_SCRIPT, "New Tabs position! …");
function main()     
    {
        var mySel = app.selection[0],
        myStops = mySel.tabStops,
        S = myStops.length,
        x = mySel.pointSize;
        mySel.pointSize = y;
        for ( var s = 0 ; s < S; s++ )  myStops.position = myStops.position/x*y;
    }

Hi,

For me it looks like direction of loop matter.

If original pointSize is higher than UI value ==> step++

Else ==> step --

/...
        if (mySel.pointSize > y)
            for ( var s = 0 ; s < S; s++ ) 
                myStops.position = myStops.position/x*y; 
      else
            for ( var s = S-1 ; s >= 0; s-- ) 
                myStops.position = myStops.position/x*y; 
//...

Thats to avoid interaction inbetween currently modified tabStop and the next ones (which possibly would change a position [index])

Hi,

The problem seems to be when a position exceeds or comes before another tab order is no longer good, right?

Bonjour

Le problème semble être quand une position dépasse ou viens avant un autre tabulation l'ordre n'est plus bon, non?

Je viens de faire des tests là ça fonction mais probablement incomplet dans les propriété :

/...
var positions=[];
   for ( var s = 0 ; s < S; s++ )  { 
            positions.push([myStops.alignment, myStops.position] );
    }
    myStops.everyItem().remove();
     for ( var s = 0 ; s < S; s++ )  { 
           mySel.tabStops.add({alignment:positions[0], leader:"", position:(positions[1]/x*y)})
     }
.../

Thanks Jarek and Philippe!

I think it works fine now as:

function main()     
    {
        var mySel = app.selection[0],
        myStops = mySel.tabStops,
        S = myStops.length,
        x = mySel.pointSize;
        mySel.pointSize = y,
        myStops_0 = [];  
        for ( var s = 0 ; s < S; s++ )  myStops_0.push([myStops.alignment, myStops.leader, myStops.position]);  
        myStops.everyItem().remove();  
        for ( var s = 0 ; s < S; s++ )  myStops.add({alignment: myStops_0[0], leader: myStops_0[1], position: myStops_0[2]/x*y});
    }
