Regex

By default, Lucee uses the older Oro Regex Engine, which is compatible with ACF.

Since 5.3.8.79, Lucee also supports using the more modern, compatible engine built into java.

You can switch engines using the following options in your Application.cfc / <cfapplication>

this.regex.engine = "java";  // default is "perl"
// or 
this.useJavaAsRegexEngine = true;

To switch between Regex engines on the fly (<cfapplication> only affects the current thread / request )

<!--- do perl regex stuff --->
<cfapplication action=“update” regex=“java”>
<!--- do modern java regex stuff --->
<cfapplication action=“update” regex=“perl”>
<!--- back to cperl  regex stuff --->
