NAME Acme::CPANModules::InterestingTies - List of interesting uses of the tie() interface VERSION This document describes version 0.001 of Acme::CPANModules::InterestingTies (from Perl distribution Acme-CPANModules-InterestingTies), released on 2023-10-31. DESCRIPTION The perl's tie interface allows you to create "magical" scalar, array, hash, or filehandle. When you read or set the value of these variables, various things can be triggered. This Acme::CPANModules list catalogs some of the interesting uses of the tie() interface. ACME::CPANMODULES ENTRIES Acme::Tie::Formatted Author: MCMAHON This module allows you to do sprintf() by accessing a hash key, e.g.: print $format{17, "%03x"}; will output: 011 The nice thing about this is that the $format{...} term can be put inside double quote, although you have to use a different quote inside the quote, e.g.: print "The value is: $format{17, '%03x'}"; print qq(The value is: $format{17, "%03x"}); The module advertises the functionality as "printf inside print", although the author chose to accept a different argument order than printf. Instead of: FORMAT, LIST the FORMAT is put at the end: LIST, FORMAT Regexp::Common Author: ABIGAIL This module contains a collection of regular expression patterns. To access the patterns, you can use the tied hash %RE, e.g.: $RE{quoted} $RE{num}{real} You can also give arguments to customize the generated pattern: $RE{delimited}{-delim=>'/'}] The advantage, again, is being able to be used inside a regular expression pattern. Note that the module also offers subroutine-based interface. I also created an alternative module called Regexp::Pattern which opts for the non-magical subroutine-based interface and offers smaller startup overhead. FAQ What is an Acme::CPANModules::* module? An Acme::CPANModules::* module, like this module, contains just a list of module names that share a common characteristics. It is a way to categorize modules and document CPAN. See Acme::CPANModules for more details. What are ways to use this Acme::CPANModules module? Aside from reading this Acme::CPANModules module's POD documentation, you can install all the listed modules (entries) using cpanm-cpanmodules script (from App::cpanm::cpanmodules distribution): % cpanm-cpanmodules -n InterestingTies Alternatively you can use the cpanmodules CLI (from App::cpanmodules distribution): % cpanmodules ls-entries InterestingTies | cpanm -n or Acme::CM::Get: % perl -MAcme::CM::Get=InterestingTies -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n or directly: % perl -MAcme::CPANModules::InterestingTies -E'say $_->{module} for @{ $Acme::CPANModules::InterestingTies::LIST->{entries} }' | cpanm -n This Acme::CPANModules module also helps lcpan produce a more meaningful result for "lcpan related-mods" command when it comes to finding related modules for the modules listed in this Acme::CPANModules module. See App::lcpan::Cmd::related_mods for more details on how "related modules" are found. HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at .

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2023 by perlancar .
