Acme::CPANModules::OneLinerTools - Modules to make your life easier when writing perl one-liners

VERSION

This document describes version 0.003 of Acme::CPANModules::OneLinerTools (from Perl distribution Acme-CPANModules-OneLinerTools), released on 2020-02-07.

DESCRIPTION

Modules to make your life easier when writing perl one-liners.

INCLUDED MODULES

• L

  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

  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::Any::App

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

• Log::ger::App

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

• DD::Dummy

  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

  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

  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

  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

  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"); ...'

FAQ

What are ways to use this module?

Aside from reading it, you can install all the listed modules using cpanmodules:

% cpanmodules ls-entries OneLinerTools | cpanm -n

or Acme::CM::Get:

% perl -MAcme::CM::Get=OneLinerTools -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n

This module also helps lcpan produce a more meaningful result for lcpan related-mods when it comes to finding related modules for the modules listed in this Acme::CPANModules module.
