Count characters not including backslash

First time post new user.

I would like a macro/script that counts the number of characters not including \ then divide that by 2 and display the result.

Seems easy but I'm struggling with it.

Thanks

If a string is selected, the number of selected bytes (not characters) are displayed in the status bar at bottom of UE main window.

It is also possible to use Search - Word Count which contains the number of selected characters.

But it is of course possible to write a simple UltraEdit script to get the number of characters divided by 2 ignoring all backslashes.

Code: Select all

if (UltraEdit.document.length > 0)  // Is any file opened?
{
   // Define environment for this script.
   UltraEdit.insertMode();
   if (typeof(UltraEdit.columnModeOff) == "function") UltraEdit.columnModeOff();
   else if (typeof(UltraEdit.activeDocument.columnModeOff) == "function") UltraEdit.activeDocument.columnModeOff();

   var nTotalChars = 0;
   var bSelectAll = false;

   // Select entire file if there is currently nothing selected.
   if (!UltraEdit.activeDocument.isSel())
   {
      var nLineNum = UltraEdit.activeDocument.currentLineNum;
      var nColumnNum = UltraEdit.activeDocument.currentColumnNum;
      if (typeof(UltraEdit.activeDocumentIdx) == "undefined") nColumnNum++;
      UltraEdit.activeDocument.selectAll();
      bSelectAll = true;
   }
   // Process selection only if there is now a selection at all,
   // i.e. the file is not an empty file.
   if (UltraEdit.activeDocument.isSel())
   {
      // Get selected text with all backslashes removed.
      var sCharsNoBackslash = UltraEdit.activeDocument.selection.replace(/\\/g,"");
      nTotalChars = sCharsNoBackslash.length;
      // Change an odd number to next even number.
      if (nTotalChars & 0x01) nTotalChars++;
      // Divide number of characters by 2.
      nTotalChars >>= 1;
   }
   if (bSelectAll)   // Cancel the selection and set caret back to initial
   {                 // position in file if the entire file was selected before.
      UltraEdit.activeDocument.gotoLine(nLineNum,nColumnNum);
   }
   UltraEdit.messageBox("Number of characters is: "+nTotalChars.toString(10));
}

Note: This script does not work for files of any size as it loads the selected block or entire file into memory which fails if file is very large.
