KRegExpEditor - Fun With Regular Expressions

KDE comes with a regular expression editor called KRegExpEditor. It allows for writing and editing regular expressions graphically rather than using plain ASCII syntax. Regular expressions are typically used to make text searches more flexible, for example if you are searching for occurrences of a particular word and want to allow for common misspellings for that word.

Regular expressions are extremely useful but are widely underused since their syntax is not very intuitive and they are difficult to read. KRegExpEditor addresses these issues by providing a graphical user interface with menu items corresponding to the various features of regular expressions. The regular expressions are shown both in easy to read semi-graphical form and in the corresponding ASCII syntax form.
