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 <https://metacpan.org/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 <https://metacpan.org/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 <https://metacpan.org/author/PERLANCAR>
A convenient way to display (consume) logs if your application uses
Log::ger to produce logs.
DD::Dummy
Author: PERLANCAR <https://metacpan.org/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 <https://metacpan.org/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 <https://metacpan.org/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 <https://metacpan.org/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 <https://metacpan.org/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 <https://metacpan.org/author/SRI>
DDP From the Data::Printer distribution.
Author: GARU <https://metacpan.org/author/GARU>

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.
