Regular Expression Editor

[Carmel]

I am looking for a RegExp editor. I have one that I have used under
Windows; however, it will not obviously work on FreeBSD. What I need is
one that I can write the expression in and then have it test the
expression for both syntax and against example text that I enter. I
have not been able to locate a FOSS solution for that although there are
numerous commercial products available.
