Good Perl Resources
« on: August 23, 2009, 11:02:56 PM »
I think I have a list of bookmarks saved somewhere with a few good primers and refresher courses in Perl (or intros for the n00bs). When I get a chance later, I'll post them up. In the meantime if anyone has any good perl resources they'd like to share.. please do!

Here are the pointers I collected so far in two groups but in no particular order within the groups:
Local resources:

    * Serach the FAQ that comes with Perl: perldoc -q "SOME QUESTION"
      Specifically this did not have anything about on how to copy a file. While the FAQ is very good it is also constrained by the time of the good people who maintain it
    * Search in perldoc perlfunc
      obviously this did not have anything about file copy either and in general if there is no such function in Perl, then this is not useful
    * ActivePerl users (at least on Windows) have HTML version of the documentation
    * In his post Tad McClellan gave a nice step-by-step approach to solve the problem

On-line resources:

    * Google groups and the Advanced search of Google Groups
    * Regular search using Google
    * News groups - comp.lang.perl.misc,comp.lang.perl.modules, and several others (The news server of perl.org)
    * Ask on the IRC)
    * search.cpan.org
    * www.perldoc.com but it is currently down.
    * Various mailing lists for beginners
    * PerlMonks
    * Find the local Perl Mongers (mailing list, personal contact whatever)

Still, I'd be interested in other ways, monks might use:
So

When you have a question such as "how to copy a file", what do you do to find a solutions ?
Do you prefer to use local resources or on-line resources ?
If you are coming from another programming languages, how would you look for an answer in that language ?
Looking back to my original question, interestingly I have not even thought about International Perl Resources, but that's another issue that might be addressed here.

I learned Perl from their official site:

perl.com/pub/a/2000/10/begperl1.html

Top 10 Perl Tips

Use Perl!
    When in doubt use Perl. Whenever a project comes up you'll wonder if you should use C, C++, sh, csh, ksh, TCL, awk, Python, Sather or one of a dozen other languages. For a more detailed language discussion go here .

    Definitely use Perl before using other scripting languages like sh, csh, ksh, and awk. Perl is more powerful, more portable, and has a much larger audience of proficient programmers and available code.

    Choosing between other high end scripting languages like TCL, Python, and Sather is a harder decision to make. Python is a better pure OO language than Perl, but some may not consider Python as good a scripting language as Perl. TCL has a lot of good utilities like Expect, great integration with GUIs, TCL is simple, and is also ported to a lot of environments. TCL is also slow and has some problems as a language. Sather as an Eiffle varient has a lot to offer too.

    With the addition of complex data structures, OO capabilities, and almost complete Unix OS integration Perl5 has become a viable alternative to using C++. Perl's interpreted environment makes using Perl a pleasure in comparison with the compile and link cycle torture of large C++ programs.

    There are clear cases where Perl is not an appropriate choice:

    High Performance Situations
        Perl is not as fast as C or C++ for many categories of applications. I would not use Perl to code a telecom switch. I would not use Perl to implement a high transaction capable database server. But I would use Perl to implement almost anything else. Perl is faster than you think. Before blowing off Perl for performance reasons you might want to run some benchmarks first.

        And of course if you are dealing with a lot of text manipulation or regular expression matching then Perl will likely be faster than most C programs you could write.

    Long Lived High Activity Servers
        I've found servers dealing simultaneously with subsecond timers, SIGCHLD, other signals, and a high transaction rate eventaully die for memory corruption reasons. Others may not have had this experience, but I cannot recommend Perl for these type of applications.

    Integration with Existing Frameworks
        If most of your project is in C or C++ then Perl may not be appropriate. It's still not easy to integrate Perl and C so writing wrappers may not be worth the effort. One good approach in these situations is to create a gateway program that uses a message based interface so you can send requests/replies between a C or C++ based server from Perl clients.

While not a sufficient reason to use a language it helps a lot if a language is fun to use.

Perl was built by programmers for programmers, not to win language design purity contests. When using Perl you feel at home. You say what you mean and mean what you say. Perl is quick to the point with an economy of expression. You can do everything you could do in C but with much less coding effort. Make a change and run the program. Perl has a powerful engine, responsive handling, and yet sports a roll bar. It's not for amateurs. Perl is how programming should be.

It is also popular to use MySQL for databases, but you could also use the Microsoft MSL server and ASP pages.  The important thing to do is to ensure that you are being provided with a server that is Windows based.  PHP and Perl are also typical as programming languages.
