GLOBAL FIND AND REPLACE Window

1. Enter the text to be found into the 'Find what' field.
2. If desired, you can set some find options by clicking the following toolbar icon:
   
   (See section below for a description.)
   Here, you can use wildcards or regular expressions.
   

   Note Incorrect 'Find options' may lead to an invalid search result. Make sure that the checked options are suitable for the entered search string.

3. Press <Enter> or click the 'Find All' button:
   

   All found occurrences are now listed as expandable result list in the window. (For each search operation, a new result list is added on top introduced by the icon.)

   • Click the toggle icons / at the beginning of each result list to expand/collapse the list.
   • You can directly access the location (editor or table) where the string was found by simply double-clicking an entry in a result list.
4. To replace text, enter the desired string into the 'Replace with' field.
   • Click 'Replace' to replace only the occurrence selected in the result list. This command is only active after selecting a found occurrence in an expanded result list.
   • Click 'Replace All' to replace all occurrences of the found string, independently of any selection in the result list.

     'Replace All' is not available in safety-related POUs. Replace occurrences manually. Refer to the section "Toolbar" below for details.

   After executing 'Replace All', an new expandable result list is added, listing the done replace operations. The new result list is added on top, introduced by the icon.
   Click the toggle icons / at the beginning of each result list to expand/collapse the list.

Button	Description
	Finds all occurrences of the search string.
	Shows the find options which allow you to customize the search.
	Replaces the current occurrence of the search string by the replace string.
	Replaces all occurrences of the search string by the replace string. 'Replace All' is not available in safety-related POUs. Replace manually instead... The 'Replace All' command does not consider text occurrences in safety-related SNOLD worksheets (i.e., they are not replaced). Found occurrences are, however, listed in the result list. You can jump to the code position (see description below) and replace the occurrence manually. Example:
	Cancels the ongoing search (button is only active while a search is being performed).

• Jump: directly jumps to the location (editor or table) where the string was found (same function as double-clicking the entry in the result list). The command is not available for result list headings.
• Copy: copies the selected result list entry to the clipboard for further processing in a conventional ASCII editor. For a selected result list heading, all contained entries are copied.
• Clear All Sessions: empties the window by deleting all result lists. To delete a specific result list, select the list and press <Del> or select the 'Delete' command from the results list's context menu.

The find options are displayed by clicking the button on the search bar.
The following options act as filters if checked. The button is highlighted with a yellow border if a find option is activated.

Find option	Description
Find backward	If activated, the search string is searched (and replaced) backward inside the editor from the current cursor position/selected object in the editor to the top of the editor. In case the top of the editor is reached, the search will automatically restart from the end of the editor.
Match Case	If activated, the search is done case-sensitive: only text matching upper and lower cases of the entered search string is found.
Match whole word	The found text has to match with the whole search text. Like 'Match Case', this option is also useful to limit the number of found text occurrences.
Use wildcards	The use of the wildcards '*' and '?' is allowed in the search text: ? represents a single character in the search string, * represents one or more characters in the search string. The wildcards can be combined in the search string.
Use regular expressions	Regular expressions allow more complex text searches by entering particular search patterns, i.e., search strings that follow a defined syntax. The most relevant expressions are listed below.

As PLCnext Engineer is based on .NET, thus using the Regular Expression Language, more regular expressions are available than these listed here. The table, however, only lists expressions useful in practice of PLCnext Engineer.

Note The expressions shown below can be combined.

Expression	Description	Examples
*	Quantifier: matches the previous element zero, one or more times.	'Find what': \d*.5 Found: 1.5, 999.5, .5
+	Quantifier: matches the previous element one or more times.	'Find what': o+ ('Match Case' unchecked) Found: OO in BOOL and o in PLCMODE_ON (variable name)
|	Alternation, i.e., logical OR combination of search terms: matches any one term separated by the | character.	'Find what': In(Var|Signal) Found: InVar and InSignal
[first-last]	Character range: matches any single character in the range from first to last.	'Find what': [A-C] Found: A and C in ACDC1974 'Find what': [1-5] Found: 1 and 4 in ACDC1974
[c1..c2..c3]	Character selection: matches each single character specified within brackets, separated by "..".	'Find what': [1..4..7] Found: 1 and 4 and 7 in ACDC1974
\d	Character selection: matches any decimal digit.	'Find what': \d Found: Text worksheet: 0 and 1 in C001 Graphical worksheet: literal containing a decimal number as well as CTD_1 instance name.
\s	Character selection: matches any white space.	'Find what': \s Found: Graphical worksheet: spaces in comments
^	Position anchor: the match must start at the beginning of the string or line.	'Find what': ^CTD Found: Text worksheet: CTD_1 in CTD_1 : CTD; Graphical worksheet: instance name and FB name, standing alone Variables table: type in instance declaration
$	Position anchor: the match must start at the end of the string or line.	'Find what': TON$ Found: Graphical worksheet: instance name, standing alone, and TON at the end of the comment string.
