DIRegEx is a library of Delphi (Embarcadero / CodeGear / Borland) components and procedures that implement regular expression pattern matching using the same syntax and semantics as Perl 5.10, with just a few differences. This includes support for UTF-8 encoded strings and Unicode general category properties.
DIRegEx offers two regular expression algorithms with their corresponding wrapper classes for easy usage:
DIRegEx can do a Format and Replace based on regular expressions, a feature often required for advanced text editors and word processors. It is possible to include parts of the originally matched text into the replacement.
The List function concatenates all reg-ex matches to a single string. It allows to build lists of phone numbers, e-mail addresses, etc. with a single function call only.
DIRegEx also includes two regular expression edits: TDIRegExMaskEdit and TDIRegExComboBox. Both controls validate all keyboard input against a regular expression pattern. They work similar to Delphi's TMaskEdit, but are much more flexible and powerful.
The regular expression mask controls allow to:
TDIRegExMaskEdit is an edit control that validates all keyboard input on a keystroke by keystroke basis. It accepts characters entered only if the new text matches the regular expression mask pattern. If the new text does not match, the character is silently rejected.
TDIRegExMaskComboBox is a combo box control with essentially the same regular expression validation as TDIRegExMaskEdit.
The DIRegEx Workbench helps you to design and test your regular expressions. It allows to set all available options, measure execution times, and to save and load all settings for later use.
The DIRegEx Workbench is available as a
