Here i am sharing a regex to validate the Email.

This is an standard version of regex.

^([a-zA-Z0-9\!\#\$\%\&\'\*\+\/\=\?\^\_\`\{\|\}\~\-]+)(?:\.[A-Za-z0-9\!\#\$\%\&\'\*\+\/\=\?\^\_\`\{\|\}\~\-]+)*@([a-zA-Z0-9]([\-]?[a-zA-Z0-9]+)*\.)+([a-zA-Z0-9]{0,6})\$

It can validate email like

Valid Emails

arungupta@gmail.com
arun+gupta+ramjiki+@gmail.com
a.little.lengthy.but.fine@dept.example.com
disposable.style.email.with+symbol@example.com
other.email-with-dash@example.com
arun@daiict.ac.in
arun_gupta@gmail.com

Invalid Emails

@example.com
me.@example.com
.me@example.com
me@example..com
me.example@com
me\@example.com

Hello Guys. I have been working in Perl from last 5 moths and while writing Regular Expressions i face difficulty to understand or write the Regular expressions. Well now it’s ok, but i thought can we covert the RegEx to understandable language.
So i started an project, here is the first version of the RegExtowordV1.0.

It can accept(Parse) Strings like

^arun
^[arun]
^[a-z]
^[A-Z]
^[a-zA-Z0-9]
^[a-zA-Z0-9]Arun
^[a-zA-Z0-9]A\^\%run
[arun]
(A|R|U|N)

Basically in first version it can parse string (any word , digit special character, ^ ,[] () ).
please do give some feedback about it.
