I have created a script for index hyperlinking from external file, this is running well but very slower.
Can anyone guide me how to run faster than current speed.
//global variables
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT;
var indexIndd, myFolder, sourceDoc;
var findText1 = "(?<![-~=])\\<\\d+\\>(?![-~=])|(?<![-~=])\\<\\d+(?=[-~=tf])";
var findText2 = "(?<=\\d[-~=])\\d+(?=[f|t])|(?<=PEx-)\\<\\d+\\>";
destDoc = [];
main ();
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.INTERACT_WITH_ALL;
function main () {
indexIndd = File.openDialog ("Select index file...", filter_files, false); //select index indesign file
myFolder = Folder(indexIndd.parent);
create_book ();
open_files_from_book ();
sourceDoc = app.open(indexIndd, false);
create_hyperlink_range ();
create_hyperlink (findText1, "_n")
alert("Done!");
}
function create_book (){
var myFileList = myFolder.getFiles();
if(myFileList.length > 0){ //check file length
var myBookName = new File(myFolder + "/" + myFolder.name + ".indb"); //book name define here
if(myBookName.exists){
try {
var myBook = app.open(File(myBookName));
}catch(e) {
myBook = app.books[0];
}
} else {
var myBook = app.books.add(myBookName);
myBook.automaticPagination = false;
add_files_into_book (myFileList);
myBook.save();
}
}
}

exit(0);
