NAME

Acme::CPANModules::OneLinerTools - List of modules to make your life easier when writing perl one-liners

VERSION

This document describes version 0.005 of Acme::CPANModules::OneLinerTools (from Perl distribution Acme-CPANModules-OneLinerTools), released on 2024-06-21.

DESCRIPTION

This list also tries to catalog modules that are meant to be primarily used in one-liners.

ACME::CPANMODULES ENTRIES

L

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.

lib::xi

Author: GFUJI

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.

lib::xi works by installing a hook in @INC.

Alternate modules: Require::Hook::More

Log::ger::App

Author: PERLANCAR

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

DD::Dummy

Author: PERLANCAR

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:

PERL_XXX_DUMPER=Data::Dump

Alternate modules: XXX, Data::Printer

Devel::Confess

Author: HAARG

Forces stack trace when your application warns or dies. Used with the perl's -d flag:

% perl -d:Confess ...
% perl -d:Confess=dump ...
Carp::Patch::Config

Author: PERLANCAR

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.

DBIx::Conn::MySQL

Author: PERLANCAR

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"); ...'
DBIx::Conn::SQLite

Author: PERLANCAR

Shortcut when connecting to MySQL database in your one-liner. Instead of:

% perl -MDBI -E'my $dbh = DBI->connect("dbi:SQLite:dbname=mydb", "", ""); $dbh->selectrow_array("query"); ...'

you can type:

% perl -MDBIx::Conn::SQLite=mydb -E'$dbh->selectrow_array("query"); ...'
ojo

Author: SRI

DDP

From the Data::Printer distribution.

Author: GARU

XXX

Author: INGY

eval
this_mod

Author: PERLANCAR

lib::filter

Author: PERLANCAR

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 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.

CONTRIBUTING

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.
