Acme::CPANModules::OneLinerTools - List of modules to make your life easier when writing perl one-liners
This document describes version 0.004 of Acme::CPANModules::OneLinerTools (from Perl distribution Acme-CPANModules-OneLinerTools), released on 2023-10-29.
Author: SONGMU
One of the "module autoloader" modules, which happens to have a short name for one-liner usage. So instead of having to type this:
% perl -MOrg::Parser::Tiny -E'$doc = Org::Parser::Tiny->new->parse_file("/home/budi/todo.org"); ...'
you can now write:
% perl -ML -E'$doc = Org::Parser::Tiny->new->parse_file("/home/budi/todo.org"); ...'
"Module autoloader" modules work using Perl's autoloading mechanism (read perlsub for more details). By declaring a subroutine named AUTOLOAD in the UNIVERSAL package, you setup a fallback mechanism when you call an undefined subroutine. L's AUTOLOADER loads the module using Module::Load then try to invoke the undefined subroutine once again.

This module can automatically install missing module during run-time using cpanm. Convenient when running a Perl script (that comes without a proper distribution or cpanfile) that uses several modules which you might not have. The alternative to lib::xi is the "trial and error" method: repeatedly run the Perl script to see which module it tries and fails to load.
cpanm
cpanfile
lib::xi works by installing a hook in @INC.

Alternate modules: Require::Hook::More

A convenient way to display (consume) logs if your application uses Log::Any to produce logs.

My preference when dumping data structure when debugging Perl application is, well, Perl format (unlike some others which prefer custom format like Data::Printer). The DD-Dummy distribution provides DD module, which in turn exports dd to dump your data structures for debugging using Data::Dump. Another good alternative is XXX which by default uses YAML output but can be changed with this environment variable setting:
dd
PERL_XXX_DUMPER=Data::Dump
Alternate modules: XXX, Data::Printer

Forces stack trace when your application warns or dies. Used with the perl's -d flag:
-d
% perl -d:Confess ... % perl -d:Confess=dump ...
Carp is used as a stack trace printer (also indirectly if you use Devel::Confess). Sometimes you want to customize some Carp parameters like $Carp::MaxArgNums and $Carp::MaxArgLen from the command-line, and this is where this module helps.
Shortcut when connecting to MySQL database in your one-liner. Instead of:
% perl -MDBI -E'my $dbh = DBI->connect("dbi:mysql:database=mydb", "someuser", "somepass"); $dbh->selectrow_array("query"); ...'
you can type:
% perl -MDBIx::Conn::MySQL=mydb -E'$dbh->selectrow_array("query"); ...'
% perl -MDBI -E'my $dbh = DBI->connect("dbi:SQLite:dbname=mydb", "", ""); $dbh->selectrow_array("query"); ...'
% perl -MDBIx::Conn::SQLite=mydb -E'$dbh->selectrow_array("query"); ...'
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.
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 OneLinerTools
Alternatively you can use the cpanmodules CLI (from App::cpanmodules distribution):
% cpanmodules ls-entries OneLinerTools | cpanm -n
or Acme::CM::Get:
% perl -MAcme::CM::Get=OneLinerTools -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n
or directly:
% perl -MAcme::CPANModules::OneLinerTools -E'say $_->{module} for @{ $Acme::CPANModules::OneLinerTools::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.

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
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.
