Hi all,

I want to replace all 0000 at the beginning of every line in the actual file with two letters AB with a script.

Code: Select all

00000012345678 . . .
00000001234567 . . .
00000000123456 . . .
00000012345678 . . .
My code:

Code: Select all

UltraEdit.activeDocument.top();
UltraEdit.activeDocument.findReplace.replaceAll=true;
UltraEdit.activeDocument.findReplace.matchCase=true;
UltraEdit.activeDocument.findReplace.replace("0000", "AB");
Result:

Code: Select all

AB0012345678 . . .
AB0001234567 . . .
ABAB123456 . . .
AB0012345678 . . ..
My first try with a script is not really good.
Line 3 should be:

Code: Select all

AB0000123456 . . .
How to solve this problem?

There must be used a regular expression replace with the anchor % (UltraEdit) or ^ (Unix/Perl) for matching only 0000 at beginning of a line.

Code: Select all

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

   // Move caret to top of the active file.
   UltraEdit.activeDocument.top();

   // Define all parameters for an UltraEdit regular expression replace
   // all in entire active file searching for the string 0000 at beginning
   // of a line and replace each found occurrence with the string AB.
   UltraEdit.activeDocument.findReplace.mode=0;
   UltraEdit.activeDocument.findReplace.matchCase=true;
   UltraEdit.activeDocument.findReplace.matchWord=false;
   UltraEdit.activeDocument.findReplace.regExp=true;
   UltraEdit.activeDocument.findReplace.searchDown=true;
   // The IF condition is for UltraEdit version 13.xx which does not have
   // the search in column feature. Just the line inside the IF condition
   // is needed on newer versions of UltraEdit.
   if (typeof(UltraEdit.activeDocument.findReplace.searchInColumn) == "boolean")
   {
      UltraEdit.activeDocument.findReplace.searchInColumn=false;
   }
   UltraEdit.activeDocument.findReplace.preserveCase=false;
   UltraEdit.activeDocument.findReplace.replaceAll=true;
   UltraEdit.activeDocument.findReplace.replaceInAllOpen=false;
   UltraEdit.ueReOn();     // UltraEdit regular expression engine
   UltraEdit.activeDocument.findReplace.replace("%0000", "AB");
}
The last two lines above the last line with just } could be also:

Code: Select all

   UltraEdit.unixReOn();   // Unix regular expression engine
   UltraEdit.activeDocument.findReplace.replace("^0000", "AB");
or

Code: Select all

   UltraEdit.perlReOn();   // Perl regular expression engine
   UltraEdit.activeDocument.findReplace.replace("^0000", "AB");

Mofi, your code solution works for me.
Thanks!
