            description => <<'MARKDOWN',

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

MARKDOWN
            tags => ['logging'],
        },

        {
            module => 'DD::Dummy',
            description => <<'MARKDOWN',

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

    PERL_XXX_DUMPER=Data::Dump

MARKDOWN
            alternate_modules => ['XXX', 'Data::Printer'],
            tags => ['debugging'],
        },

        {
            module => 'Devel::Confess',
            description => <<'MARKDOWN',

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

    % perl -d:Confess ...
    % perl -d:Confess=dump ...

MARKDOWN
            tags => ['debugging'],
        },

        {
            module => 'Carp::Patch::Config',
            description => <<'MARKDOWN',

<pm:Carp> is used as a stack trace printer (also indirectly if you use
<pm: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.

MARKDOWN
            tags => ['debugging'],
        },

        {
            module => 'DBIx::Conn::MySQL',
            description => <<'MARKDOWN',

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"); ...'

MARKDOWN
            tags => ['database', 'dbi'],
        },

        {
            module => 'DBIx::Conn::SQLite',
            description => <<'MARKDOWN',

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"); ...'

MARKDOWN

=head1 NAME

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

=head1 VERSION

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

=head1 DESCRIPTION

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

=head1 ACME::CPANMODULES ENTRIES

=item L<L>

Author: L<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
C<perlsub> for more details). By declaring a subroutine named C<AUTOLOAD> in the
C<UNIVERSAL> package, you setup a fallback mechanism when you call an undefined
subroutine. L<L>'s AUTOLOADER loads the module using L<Module::Load> then
try to invoke the undefined subroutine once again.

distribution or C<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 C<@INC>.


Alternate modules: L<Require::Hook::More>

=item L<Log::ger::App>

Author: L<PERLANCAR|https://metacpan.org/author/PERLANCAR>

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


=item L<DD::Dummy>

Author: L<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
L<Data::Printer>). The DD-Dummy distribution provides L<DD> module, which in
turn exports C<dd> to dump your data structures for debugging using
L<Data::Dump>. Another good alternative is L<XXX> which by default uses YAML
output but can be changed with this environment variable setting:

 PERL_XXX_DUMPER=Data::Dump


Alternate modules: L<XXX>, L<Data::Printer>

=item L<Devel::Confess>

Author: L<HAARG|https://metacpan.org/author/HAARG>

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

 % perl -d:Confess ...
 % perl -d:Confess=dump ...


=item L<Carp::Patch::Config>

Author: L<PERLANCAR|https://metacpan.org/author/PERLANCAR>

L<Carp> is used as a stack trace printer (also indirectly if you use
L<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.


=item L<DBIx::Conn::MySQL>

Author: L<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"); ...'


=item L<DBIx::Conn::SQLite>

Author: L<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"); ...'


=item L<ojo>

=head1 FAQ

=head2 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 L<Acme::CPANModules> for more details.

=head2 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 L<cpanm-cpanmodules> script (from
L<App::cpanm::cpanmodules> distribution):

 % cpanm-cpanmodules -n OneLinerTools

Alternatively you can use the L<cpanmodules> CLI (from L<App::cpanmodules>
distribution):

    % cpanmodules ls-entries OneLinerTools | cpanm -n

or L<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 L<lcpan> produce a more meaningful
result for C<lcpan related-mods> command when it comes to finding related
modules for the modules listed in this Acme::CPANModules module.
