For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Dialling codes for Ireland - a quick Perl Script

Posted by admin (Graham Ellis), 23 October 2004
With so many people writing so many complicated scripts, I thought I would share this little utility with you.

Scenario - I had data of this form:

1  Dublin Central  7 1  Dublin North  7 1  Dublin South  7    21  Cork  7 21  Coachford 7 21  Kinsale  7 22  Mallow  5 23  Bandon  5 24  Youghal  5 25  Fermoy  5 26  Macroom 5 27  Bantry  5 28  Skibbereen 5 29  

and I wanted:

003531 Dublin Central
003531 Dublin North
003531 Dublin South
0035321 Cork
0035321 Coachford
0035321 Kinsale
0035322 Mallow
0035323 Bandon
0035324 Youghal
0035325 Fermoy

Quick solution - a Perl script

while (<>) {
       @have = /\d+\s+\D+/g;
       print join("\n",@have);

followed by a quick global edit of the output to add in the "00353"s.

Perl is a excellent tool for this sort of thing ... I've just done something similar for the codes for Mexico, but that's a whole different 6 line script!
