So I come to the discussion having asked,
I want to cut over to perl5 for what reason?
Since I had crawled up the learning curve the old fashion way,
Beating My Head Against the WALL
until the information sunk in
p1: you will want to become friends with
perldoc perl
which will give you the inventory of the available online
documentation about perl, and pay attention to
perldoc perlboot
perltoot
perltootc
perlobj
perlbot
for the stock snappy intro to basic OO-ing in perl.
p2: once upon a time, a long, long, long time ago, there
was not good perldoc, and the world was dark, and filled
with BatWingedSpawnsOfSatanFromTheDeepistPitsOfGehenna that
ate young coders and spit out their bones
[..]
My /real/ problem is that object oriented code is a foreign language.
p3: At the risk of igniting a HolyWar, one of the advantages you
gain from playing in Perl5 is that you can swing either way. So
that you understand, when I use the token 'method' - it is more
in line with 'method in my madness' than the OO token. If you look
at some of the cooler perl modules, they allow them to be used as
both 'methods', in the OO sense, or as 'functions' in the functionalist
sense.
In my current project I have modules that are OO'd, because the
data said, Yeah I am Objectionable, so I Objected...
{ the voices in my head make me write it that way }
I have other modules that are dull boring pedantic pedstrian stacks
of functions without a new to bless an object. Because I just needed
to stack some common functions in a common place and find them...
p4: Scott and Andrew have offered the usual Suspects, although I
will have to see this with
'Learning Perl Objects, References, and Modules'
when it comes out - having Bashed my head against merely
the 'perldoc' for such things.
My job is with microwave comms hardware and I have no need to do
software at all, so an explanation which is plain as day to people
who speak the language is far from that to a raw beginner like me.
[..]
There is also the additional fun, namely that in the CGI space
you need to understand not MERELY the basics of 'perl stuff' but
also the other bits and bobs about 'html' and 'http' - depending
upon your level of psychosis - and most likely a bit of Javascripting,
since, well, there are things that should just be resolved on the
browser side of the line BEFORE they come back to the server.
So on top of the other section I include the obligatory
Programming Perl - 3rd Edition -
ISBN: 0-596-00027-8
{ just buy it! Read it based upon what you found in
the index in the back, then check the perldoc to see
if some things have changed and/or 'best practices' notes
show up that help explain things better... }
Perl 5 pocket reference
ISBN: 0-596-00032-4
{ because if you have a life, sometimes it's less important
to retain all the syntactic goo for RegEx, et al, than
things like your name, home address, phone number. And
it's embarrassing to get carpal tunnel pulling the 3rd Edition
out all the time... }
Dynamic HTML - the Definitive Reference - Nth Edition
ISBN:0-596-00316-1
{ it would have been nice to have One DOM to rule them all,
but this is the 'real world' or as close as we'll get,
so own the dictionary, look up the words... }
JavaScript - The Definitive Guide - Nth Edition
ISBN: 0-596-00048-0
{ op cit, Frodo did not get to Mordor, deal with it... }
Technically you are not obliged to have read the full works of
J.R.R. Tolkien, you can crib with reading 'bored of the rings'.
But you should read everything by Chomsky, C.S. Lewis, and most
importantly all the back issues of Mad Magazine...
Then you will understand the mental stains that programmers
use to emmulate human conversation... Unless they are Orcs

Learning Perl
Hi all I have started learning perl language and to this effort I have bought the book programming perl from O\'Reilly .Can anyone tell me whether this one is okay and how to exactly go forward learning perl.What things to be learnt first etc. Any help is g8ly appreciated.

There is a book also called Learning Perl from O'Reilly, but really I don't feel there is a suitable enough reason to pay a lot of money for it, especially since you have Programing Perl already. Programming Perl is very detailed, and reading that book should teach you a lot of perl. Talking to other Perl Programmers is important too. The most important thing is progressive practice. As this is a CGI mailing list, I thought I'd mention that the book I began learning off of was Perl and CGI for the World Wide Web: Visual Quickstart Guide by Castro. I thought is was good, it taught me the basics. I was just some web designer that wanted to learn some Perl. After than one I read Programming Perl, I did not buy it though, I went to the library.

RE: Learning Perl
Perl and CGI for the World Wide Web: Visual Quickstart Guide by Castro. So true. I agree on this. I personally got the Perl: A Beginners Guide but I like how the Visual Quickstart Guides are done, except they are done on an old Mac box from the mid-90's. Other than that i love the Visual Quickstart Guides. I personally like using a Quickstart Guide or Beginners Guide and then jump straight to the reference manuals and web tutorials. There are a lot of web tutorials out there and they are good too. Just my 2 cents. Rob -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Learning Perl
both of these options are great. but I'll tell you what I did. I bought a copy of the perl cd bookshelf on www.half.com that's the first one not the second one. Learning Perl 2nd Edition is on the cd along with perl in a nutshell, Programming Perl, 2nd edition, Perl Cookbook, Advanced Perl Programming and Learning Perl on Win32 Systems... It is an awesome resource if you don't mind reading on your computer. its a great resource for anyone serious about perl. - Original Message - From: fliptop [EMAIL PROTECTED] To: Randal L.

There is a [EMAIL PROTECTED]mailing list that is specifically aimed at general perl beginning questions. If you are coming from a 'c' or 'c++' background, then most of the general syntax will map easily onto what you already know about programming. Either way you will also want to become fast friends with perldoc perl since perl offers a lot of internal documentation. I saved off some of the basic perl web sites at: http://www.wetware.com/drieux/pbl/perldoc/ At which point you will also want to pick up books like a. CGI Programming with perl b. Dynamic HTML - the definitive reference c. JavaScript The Definitive Guide since you will find that understanding HTML will be very useful, and that there are times when you will want your perl cgi code to generate javascript stuff... ciao drieux --- -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
