  • "This Book Was a Joy to Read. It Covered All Sorts of Techniques for Debugging, Including 'Defensive' Paradigms That Will Eliminate Bugs in the First Place
    Perl Debugged By Peter Scott, Ed Wright Publisher : Addison Wesley Pub Date : March 01, 2001 ISBN : 0-201-70054-9 Table of • Pages : 288 Contents "This book was a joy to read. It covered all sorts of techniques for debugging, including 'defensive' paradigms that will eliminate bugs in the first place. As coach of the USA Programming Team, I find the most difficult thing to teach is debugging. This is the first text I've even heard of that attacks the problem. It does a fine job. Please encourage these guys to write more." -Rob Kolstad Perl Debugged provides the expertise and solutions developers require for coding better, faster, and more reliably in Perl. Focusing on debugging, the most vexing aspect of programming in Perl, this example-rich reference and how-to guide minimizes development, troubleshooting, and maintenance time resulting in the creation of elegant and error-free Perl code. Designed for the novice to intermediate software developer, Perl Debugged will save the programmer time and frustration in debugging Perl programs. Based on the authors' extensive experience with the language, this book guides developers through the entire programming process, tackling the benefits, plights, and pitfalls of Perl programming. Beginning with a guided tour of the Perl documentation, the book progresses to debugging, testing, and performance issues, and also devotes a chapter to CGI programming in Perl. Throughout the book, the authors espouse defensible paradigms for improving the accuracy and performance of Perl code. In addition, Perl Debugged includes Scott and Wright's "Perls of Wisdom" which summarize key ideas from each of the chapters, and an appendix containing a comprehensive listing of Perl debugger commands.

  • Name Description
    Perl version 5.10.0 documentation - perlnewmod NAME perlnewmod - preparing a new module for distribution DESCRIPTION This document gives you some suggestions about how to go about writingPerl modules, preparing them for distribution, and making them availablevia CPAN. One of the things that makes Perl really powerful is the fact that Perlhackers tend to want to share the solutions to problems they've faced,so you and I don't have to battle with the same problem again. The main way they do this is by abstracting the solution into a Perlmodule. If you don't know what one of these is, the rest of thisdocument isn't going to be much use to you. You're also missing out onan awful lot of useful code; consider having a look at perlmod, perlmodlib and perlmodinstall before coming back here. When you've found that there isn't a module available for what you'retrying to do, and you've had to write the code yourself, considerpackaging up the solution into a module and uploading it to CPAN so thatothers can benefit. Warning We're going to primarily concentrate on Perl-only modules here, ratherthan XS modules. XS modules serve a rather different purpose, andyou should consider different things before distributing them - thepopularity of the library you are gluing, the portability to otheroperating systems, and so on. However, the notes on preparing the Perlside of the module and packaging and distributing it will apply equallywell to an XS module as a pure-Perl one. What should I make into a module? You should make a module out of any code that you think is going to beuseful to others.

  • Name Synopsis Description Main Methods
    Perl version 5.10.0 documentation - Pod::Simple NAME Pod::Simple - framework for parsing Pod SYNOPSIS TODO DESCRIPTION Pod::Simple is a Perl library for parsing text in the Pod ("plain olddocumentation") markup language that is typically used for writingdocumentation for Perl and for Perl modules. The Pod format is explainedin the perlpod man page; the most common formatter is called"perldoc". Pod formatters can use Pod::Simple to parse Pod documents into producerenderings of them in plain ASCII, in HTML, or in any number of otherformats. Typically, such formatters will be subclasses of Pod::Simple,and so they will inherit its methods, like parse_file. If you're reading this document just because you have a Pod-processingsubclass that you want to use, this document (plus the documentation forthe subclass) is probably all you'll need to read. If you're reading this document because you want to write a formattersubclass, continue reading this document, and then read Pod::Simple::Subclassing, and then possibly even read perlpodspec(some of which is for parser-writers, but much of which is notes toformatter-writers). MAIN METHODS $parser = SomeClass->new(); This returns a new parser object, where SomeClass is a subclassof Pod::Simple. $parser->output_fh( *OUT ); This sets the filehandle that $parser's output will be written to.You can pass *STDOUT, otherwise you should probably do somethinglike this: my $outfile = "output.txt"; open TXTOUT, ">$outfile" or die "Can't write to $outfile: $!"; $parser->output_fh(*TXTOUT); ...before you call one of the $parser->parse_whatever methods. $parser->output_string( \$somestring ); This sets the string that $parser's output will be sent to,instead of any filehandle.
