This page exists as a resource for Regular Expressions (also shortened as RegEx or RegExp) frequently used in EditPlus. In order to learn more about the particulars of creating a regular expression in EditPlus, see regular expression syntax. Also note that some standard regular expressions are currently not supported.
Note: EditPlus only supports [POSIX] Regular Expressions, not [PCRE] (Perl-Compatible Regular Expressions), which means there are no back-references, no look-aheads, no fancy quantifiers, and no convenient character group syntax]]. Just your basic ^, $, +, *, ?, [ ], [^ ], syntax. Also note that +/* are always greedy.
