#RegExThursday
Regular Experssions - One Page at a Time
| If
you want to learn how to write regular experssions, you have come to
the
right place. Every Thursday I'll be posting a single page of
a booklet that
I hope to write with you about regular experssions. Together we are
going to explore why writing regular expressions are so useful, and
we'll
learn how to write increasingly complex regular expressions. If there is any specific topic within regular experssions that you would like to learn, send me an email at DamianTGordon(a)gmail.com and we'll work together on that topic. Below, in grey text, I have put in a few of the upcoming pages we might see in this exploration of regular expressions, but these are subject to change, and subject to your suggestions. |
