[Preston] Regular expressions: Topic for the June Meeting

[Guy Heatley]

Hello!
I'm pleased to announce that Dr John McMullin will be giving us the 
benefit of his expertise in the field of regular expressions at the PLUG 
meeting on Tuesday.

Regular expressions are a shorthand way of telling a computer program to 
match certain patterns. They are useful in the field of text processing 
(e.g. validating user input on web forms) and also in software like 
compilers where high-level code must be transformed into machine code. 
The lexical analyser looks for patterns in the code the programmer 
writes in order to process it. e.g keywords, variable names, correct 
syntax etc.

So, if you fancy a little pattern matching, and you would like to know 
why this gibberish matches email addresses (on a case insensitive match 
of course):-
\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b

come along on Tuesday evening, 7:30pm Room CM018 at the UCLAn C&T Building

Drinks afterwards in the Greyfriar, Friargate.

Cheers!
