Learning regular expressions

[Erratus]

Need hints on how to learn regexes quickly by hack and look. Any ports or developing programs which can do this on freebsd? Found some interesting windows-solutions (RegexBuddy) but so far none UNIX/freebsd.

regex(3) and re_format(7) not enough?

[cmd=]cd /usr/ports && make search key=regular[/cmd] (or [cmd=]psearch regular[/cmd] if you have ports-mgmt/psearch installed) will also turn up some stuff, like e.g. misc/gregexp and misc/txt2regex.

No, that's not what I'm looking for. I definitivly have read all related man/info pages.
I'm looking for something like a debugger for regular expressions.

just did psearch and here's something that might help (haven't tried myself):

[port]textproc/redet[/port]            Visual regexp development and execution
[port]misc/gregexp[/port]              A graphical regular expression explorer
[port]misc/tkregexp[/port]             An interactive regexp design tool
[port]misc/txt2regex[/port]            A Regular Expression "wizard"

perhaps something of this will help you
