NAME

App::RunCron - making wrapper script for crontab

SYNOPSIS

    use App::RunCron;
    my $runner = App::RunCron->new(
        timestamp => 1,
        command   => [@ARGV],
        logfile   => 'tmp/log%Y-%m-%d.log',
        reporter  => 'Stdout',
        error_reporter => [
            'Stdout',
            'File', {
                file => 'tmp/error%Y-%m-%d.log'
            },
        ],
    );
    $runner->run;

DESCRIPTION

App::RunCron is a software for making wrapper script for running cron tasks.

App::RunCron can separate reporting way if the command execution success or failed (i.e. fails to start, or returns a non-zero exit code, or killed by a signal). It is handled by `reporter` and `error_reporter` option.

By default, `reporter` is 'None' and `error_reporter` is 'Stdout'. It prints the outputs the command if and only if the command execution failed. In other words, this behaviour causes cron(8) to send mail when and only when an error occurs.

Default behaviour is same like cronlog.

OPTIONS

timestamp

Add timestamp or not. (Default: undef)

tag

Identifier of the job name. (Optional)

command

command to be executed. (Required)

logfile

If logfile is specified, stdout and stderr of the command will be logged to the file so that it could be used for later inspection. If not specified, the outputs will not be logged. The logfile can be a strftime format. eg. '%Y-%m-%d.log'. (NOTICE: '%' must be escaped in crontab.)

reporter|error_reporter|common_reporter

common_reporter is optional, processing after (error_)?reporter is handled.

The reporter, error_reporter and common_reporter can be like following.

$module_name
[$module_name[, \%opt], ...]
$coderef

$module_name package name of the plugin. You can write it as two form like Plack::Middleware:

    reporter => 'Stdout',    # => loads App::RunCron::Reporter::Stdout

If you want to load a plugin in your own name space, use the '+' character before a package name, like following:

    reporter => '+MyApp::Reporter::Foo', # => loads MyApp::Reporter::Foo

announcer

Package name of an "Announcer" which announce job information before running the job. (Optional)

METHODS AND ACCESORS

my $str = $self->result_line

One line result string of the command.

my $str = $self->report

Retrieve the output of the command.

my $bool = $self->is_success

command is success or not.

my $int = $self->exit_code
