Perl, PCRE, and Ruby all support regular expression recursion and subroutines. While \K is not really needed in JGsoft V2 with its unrestricted lookbehind, you can now use \K in JGsoft V2 like you would in Perl or PCRE if you are used to writing your regexes that way. In Perl and PCRE you can use \K to keep text out of the match to work around their restrictions on lookbehind. JGsoft V2 does not support the syntax as this could lead people to write which behaves unpredictably in Java and Ruby. The nested pair of square brackets is required.

Just do your users a favor and state very clearly which regex flavor your application uses. Unless you’re developing a tool like PowerGREP or RegexBuddy in which regular expressions are the core functionality, the regex flavor already provided by your development environment will be more than sufficient. It was specifically designed to work within Just Great Software products, rather than as a general-purpose engine. The Just Great Software engine is not available as a component that can be embedded into other applications. When you select a regex flavor in RegexBuddy or RegexMagic, all of their features use that flavor. RegexBuddy and RegexMagic have a special version of the Just Great Software engine that can simulate the limitations and flavor-specific features of many other regular expression flavors. The engine in PowerGREP (version 3 and later) and EditPad Pro (version 7 and later) can process files larger than 4GB without splitting the files in arbitrary chunks. It fully supports Unicode and a wide range of legacy code pages. The JGsoft flavor offers a blend of all the features found in the most popular regular expression flavors. This engine and its regular expression flavor were specifically developed for PowerGREP, RegexBuddy, and RegexMagic. It also powers the regular expression search functions in EditPad Pro (version 6 and later), EditPad Lite (version 7 and later), and AceText (version 2 and later). This engine is the core of the Just Great Software products PowerGREP (version 3 and later), RegexBuddy (version 2 and later), and RegexMagic (all versions).
