Today I implemented a couple of improvements into Regex Hero. First we have a suggestion to allow the list of matched groups to be separated by tabs . This allows you to copy and paste the groups directly into a spreadsheet application like Excel. Then we have a suggestion to create cleaner code generation when IgnorePatternWhitespace is checked . This essentially means that the regex string is divided into separate lines so that the comments are still at the end of each line, making the regular expression easier to follow.
