RegExRule.png

This rule finds text that matches the specified RegEx pattern, and replaces it with another string. RegEx is short for Regular Expressions, which stands for special syntax for describing search and replace patterns. Regular Expressions are very powerful and they are really worth learning. The RegEx syntax is explained in the appendix.

Note: The TRegExpr RegEx engine used by ReNamer is a little different from the standard PERL RegEx or Windows RegEx. You may check the correct syntax in Regular Expressions section.

The parameters are as follows:

Parameter Details
Expression RegEx pattern to match or find.
Replace RegEx pattern that replaces the found pattern.
Skip extension If this check box is selected, the extension will be ignored by the rule.
Case-sensitive If this option is selected, ReNamer will search for the text in case-sensitive manner.

A simple set of commonly used RegEx syntax patterns is provided in the hint menu:

Tip: ReNamer users have posted many RegEx patterns at the User Forum. You can copy and use them.
