'''^txt2regex$''' is a regular expression (generally mentioned and used as [[Regex]]) wizard that leads the user through the construction of a regular expression by asking a series of questions. The regular expression is generated in the notation used by: [[AWK programming language|AWK, GAWK, MAWK]], [[Ed (Unix)|ed]], egrep, [[Emacs]], [[expect]], [[find]], [[grep]], [[Lex programming tool|lex]], [[Lisp programming language|Lisp]], [[MySQL]], [[OpenOffice.org]], [[Perl]], [[PHP]], [[PostgreSQL]], [[Procmail]], [[Python (programming language)|Python]], [[Sed]], [[Tcl]], [[VBscript]], [[Vi]], and [[Vim (text editor)|Vim]].
It is a useful tool for users with little or no knowledge of regular expressions and so is included in several Linux distributions, including [[Debian]], [[Gentoo Linux|Gentoo]], [[Knoppix]], and [[Mandriva]], in [[FreeBSD]], and in [[Fink]] for [[Mac OS X]].
Although graphical interfaces have typically followed command line interfaces, ^txt2regex$ is unusual in providing a command line interface for a function usually, and previously, provided by means of a graphical user interface. It is also unusual in interacting with the user to facilitate the use of what is generally regarded as a technical tool unsuitable for naive users and in supporting multiple regular expression notations.
