![]() ![]() What's a closure?Ĭlosure is a computer science term with a precise but hard-to-explain meaning. See also "Laundering and Detecting Tainted Data" in perlsec. You can use the tainted() function of the Scalar::Util module, available from CPAN (or included with Perl since release 5.8.0). See also perlootut, a tutorial that covers class creation, and perlobj. ![]() Perl doesn't get more formal than that and lets you set up the package just the way that you like it (that is, it doesn't set up anything for you). In Perl, a class is just a package, and methods are just subroutines. If there's no response to private communication or the public post, a PAUSE admin can transfer it to you. The PAUSE admins don't want to act too quickly in case the current maintainer is on holiday. Post a public message in a heavily trafficked site announcing your intention to take over the module. The PAUSE admins will also try to reach the maintainer. Write to explaining what you did to contact the current maintainer. Get a login for the Perl Authors Upload Server (PAUSE) if you don't already have one: If you can not reach the author for some reason contact the PAUSE admins at who may be able to help, but each case is treated separately. How do I adopt or take over a module already on CPAN?Īsk the current maintainer to make you a co-maintainer or transfer the module to you. perlxs and perlxstut explain the details. h2xs will create the module distribution structure and the initial interface files. If you need to include C code or C library interfaces use h2xs. Many CPAN authors now use Dist::Zilla to automate as much as possible.ĭetailed documentation about modules can be found at: perlmod, perlmodlib, perlmodstyle. Perlnewmod is a good place to start, ignore the bits about uploading to CPAN if you don't want to make your module publicly available.ĮxtUtils::ModuleMaker and Module::Starter are also good places to start. ![]() If you're looking for something a bit more rigorous, try perlootut. How can I pass/return a = "Nat" # set field NAME to "Nat".What is variable suicide and how can I prevent it?.How can I tell if a variable is tainted?.How do I adopt or take over a module already on CPAN?.Why do Perl operators have different precedence than C operators?.Do I always/never have to quote my strings or use semicolons and commas?.What are all these punctuation signs, and how do I know when to use them?.Can I get a BNF/yacc/RE for the Perl language?. ![]()
