  • Compiling Your Own Perl
    APPENDIX A Compiling Your Own Perl Compiling Perl on a Unix-like system is simple. First, obtain the source for Perl from CPAN (dppl6++_l]j*lanh*knc+on_+NA=@IA*dpih). Then input the following sequence of commands: p]nvtrblanh)1*4*4*p]n*cv _`lanh)1*4*4 od?kjbecqna)`ao i]ga i]gapaop oq`ki]gaejop]hh On most Unix systems, this code will result in your lanh being installed into the +qon+ hk_]h+ directory tree. If you want it installed elsewhere—for example, in the local directory in your home directory—then replace od?kjbecqna)`a with the following: od?kjbecqna)`ao)@lnabet9z+hk_]h+ which should enable you to install Perl on your computer without root access. Note that the )`ao flag uses all the default options for compiling Perl. If you know that you want nonstandard configuration, just use the flag )`a instead to be prompted for your requirements. Be aware that the source for Perl 5.10.0 requires a patch to work properly with Catalyst. This is fixed in subsequent versions of Perl 5.10. If you need to test code guaranteed to run on a wide range of systems, you should con- sider using Perl version 5.8.7. Perl versions greater than 5.8.7 contain features that were not available in earlier versions of Perl, so Perl 5.8.7 is feature complete for all versions of Perl that Catalyst will run on (version 5.8.1 and later). Put another way, versions 5.8.8 and later have new features that you can’t rely on in earlier releases.

As I read it, I was reminded of the first time I read K&R. It will teach everything that one needs to know to write Perl 5 well. ➤ David Golden Member, Perl 5 Porters, Autopragmatic, LLC I’m about to teach a new hire Perl using the first edition of Modern Perl.

    COLUMNS Practical Perl Tools Perl without Perl DAVID N. BLANK-EDELMAN David has over thirty years t’s not exactly a Zen koan, but it will have to do for this issue’s column. of experience in the systems Today we’re going to talk about how a method for parsing Perl without administration/DevOps/SRE using the actual Perl interpreter can offer a whole host of benefits. This field in large multiplatform I environments and is the author idea may be somewhat surprising because Perl has a reputation (perhaps of the O’Reilly Otter book (new book on SRE deserved) as being a language where “the only thing which can parse Perl forthcoming!). He is one of the co-founders (the language) is perl (the binary).” For some detailed examples of this criti- of the now global set of SREcon conferences. cism, see one of the well-known essays at http://www.perlmonks.org/index David is honored to serve on the USENIX .pl?node_id=44722, which is where that quote came from, originally attrib- Board of Directors where he helps to organize uted to Tom Christiansen. and engineer conferences like LISA and SREcon. [email protected] Part of the problem is that there are some ambiguities in the language that only resolve themselves definitively during runtime. This reality harshed many the mellow of aspiring tool creators until at some point someone asked the question, “Could we write something that could parse enough Perl to be useful? Maybe we won’t get 100% correct behavior, but how good does it have to be to let us get real work done?” Turns out, we can actually get really, really close.

On the website http://en.wikipedia.org you can not only find the current articles of Wikipedia but you can also start writing imediately without registration or identification. With this revolutionary method more than 700.000 articles were written since 2001 in more than 40 languages, and it's growing faster. In some languages Wikipedia is the first ency- clopedia ever. Since 2003 the Wikimedia Foundation is taking care of running the farm of webservers and also hosts and supports other projects like the multilinugual dictionary Wiktionary and the textbooks project WikiBooks.
