Remove unused style

[sreekarthik_k]

Hi All

I am using the below code to remove the unused style form the application file

But it's removing all GREP style mapped character style

How to fix this issue please advice

for (i = myCharStyles.length-1; i >= 1; i-- ) { 

   removeUnusedCharStyle(myCharStyles); 

}

function removeUnusedCharStyle(myChStyle) { 

   app.findTextPreferences = NothingEnum.nothing; 

   app.changeTextPreferences = NothingEnum.nothing; 

   app.findTextPreferences.appliedCharacterStyle = myChStyle; 

   var myFoundStyles = myDoc.findText(); 

      if (myFoundStyles == 0) { 

         myChStyle.remove(); 

      } 

   app.findTextPreferences = NothingEnum.nothing; 

   app.changeTextPreferences = NothingEnum.nothing; 

}

Hi,

try the following snippet. (test on cs5)

you can get appliedCharacterStyles' id in all NestedXXXStyles as Array.

on removing character styles, you can exclude these styles by ids.

thank you.

var used_charstyle_ids_in_nestedstyle = function (parastyles) {

  var ret = [];
  for (var i=0, len=parastyles.length; i < len ; i++) {
   var used_c_style_ids = [];
   var p_style = parastyles;

   var ng_styles = p_style.nestedGrepStyles;
   var nl_styles = p_style.nestedLineStyles;
   var n_styles  = p_style.nestedStyles;
  used_c_style_ids = used_c_style_ids.concat(used_charstyle_ids(ng_styles));
  used_c_style_ids = used_c_style_ids.concat(used_charstyle_ids(nl_styles));
  used_c_style_ids = used_c_style_ids.concat(used_charstyle_ids(n_styles));

  ret = ret.concat(used_c_style_ids);
  };
  return ret
}

var used_charstyle_ids = function (x_styles) {

  var ret = [];
  for (var i=0, len=x_styles.length; i < len ; i++) {
   var c_style = x_styles.appliedCharacterStyle;
  ret.push(c_style.id);
  };
  return ret
}

var is_included = function (item, list) {
  for (var i=0, len=list.length; i < len ; i++) {
   if (list === item) {
   return true
  }
  };
  return false
}

// main
var doc = app.documents[0];
$.writeln(all_used_charstyle_ids(doc));

function all_used_charstyle_ids(doc) {

  var no_charstyle_id = doc.characterStyles.item("$ID/[No Character Style]").id;
  var p = doc.allParagraphStyles;
  var ids = used_charstyle_ids_in_nestedstyle(p).concat(no_charstyle_id);

  return ids
}
