NAME

Test::Smoke::LogMixin - "Role" that adds logging methods to "traditional" objects.

SYNOPSIS

    package MyPackage;
    use warnings;
    use strict;
    use Test::Smoke::LogMixin;

    sub new {
        my $class = shift;
        my %selfish = @_;
        $selfish{_verbose} ||= 0;
        return bless \%selfish, $class;
    }
    1;

    package main;
    use MyPackage;
    my $o = MyPackage->new(_verbose => 2);
    $o->log_debug("This will end up in the log");

DESCRIPTION

This package with these mixin-methods acts like a role to extend your traditional (created with bless()) object with 4 new methods. It has some extra Test::Smoke::App::Base logic to determine the log-level (by looking at $app->option('verbose')). For other object types it tries to fiend if there are methods by the name verbose or v, or maybe the keys _verbose or _v (See also Test::Smoke::ObjectBase).

The three log methods use the sprintf() way of composing strings whenever more than 1 argument is passed!

$app->verbosity

Return the verbosity of this app.

Arguments

None.

Returns

The value of either _verbose or _v

$app->log_warn($fmt, @values)

prinf $fmt, @values to the currently selected filehandle.

Arguments

Positional.

$fmt => a (s)printf format

The format gets an extra new line if one wasn't present.

@values => optional vaules for the template.

Returns

use in void context.

Exceptions

None.

$app->log_info($fmt, @values)

prinf $fmt, @values to the currently selected filehandle if the 'verbose' option is set.

Arguments

Positional.

$fmt => a (s)printf format

The format gets an extra new line if one wasn't present.

@values => optional vaules for the template.

Returns

use in void context.

Exceptions

None.

$app->log_debug($fmt, @values)

prinf $fmt, @values to the currently selected filehandle if the 'verbose' option is set to a value > 1.

Arguments

Positional.

$fmt => a (s)printf format

The format gets an extra new line if one wasn't present.

@values => optional vaules for the template.

Returns

use in void context.

Exceptions
