METHODS

This class implements the following methods

startup

This is your main hook into the application, it will be called at application startup. Meant to be overloaded in a subclass.

This method is called immediately after creating the instance and returns it

NOTE: Please use only in your subclasses!

sub startup {
    my $self = shift;

    . . .

    return $self; # REQUIRED!
}

debugmode

$app->debugmode;

Returns debug flag. 1 - on, 0 - off

begin

my $timing_begin = $app->begin;

This method sets timestamp for "elapsed"

my $timing_begin = $app->begin;
# ... long operations ...
my $elapsed = $app->elapsed( $timing_begin );

elapsed

my $elapsed = $app->elapsed;

my $timing_begin = [gettimeofday];
# ... long operations ...
my $elapsed = $app->elapsed( $timing_begin );

Return fractional amount of time in seconds since unnamed timstamp has been created while start application

my $elapsed = $app->elapsed;
$app->log->debug("Database stuff took $elapsed seconds");

For formatted output:

$app->log->debug(sprintf("%+.*f sec", 4, $app->elapsed));

error

my $error = $app->error;

Returns error string if occurred any errors while working with application

$app = $app->error( "error text" );

Sets new error message and returns object

exedir

my $exedir = $app->exedir;

my @names = $app->handlers;

Returns list of names of registered handlers

my @names_and_aliases = $app->handlers(1);

Returns list of aliases and names of registered handlers

lookup_handler

my $handler = $app->lookup_handler($name)
    or die "Handler not found";

plugin

$app->plugin(foo => 'MyApp::Plugin::Foo');
$app->plugin(foo);
$app->plugin(foo => 'MyApp::Plugin::Foo', {bar => 123, baz => 'test'});
$app->plugin(foo => 'MyApp::Plugin::Foo', bar => 123, baz => 'test');

my $pwd = $app->pwd;

This method returns current/working directory

register_handler

use parent qw/Acme::Crux/;

__PACKAGE__->register_handler(
    handler     => "foo",
    aliases     => "one, two",
    description => "Foo handler",
    params => {
        param1 => "test",
        param2 => 123,
    },
    code => sub {
### CODE:
    my $self = shift; # App
    my $meta = shift; # Meta data
    my @args = @_; # Arguments

    print Acrux::Util::dumper({
        meta => $meta,
        args => \@args,
    });

    return 1;
});

Method for register new handler

Example output while running:

$app->run('one', abc => 123, def => 456); # returns 1

}

This method supports the following options:

aliases, alias
aliases => 'foo bar baz'
aliases => 'foo, bar, baz'
aliases => [qw/foo bar baz/]
alias => 'foo'

Sets aliases list for handler lookup

code
code => sub {
    my ($self, $meta, @args) = @_;
    # . . .
}

$app->register_method($namespace, $method, sub { 1 });
$app->register_method($method => sub { 1 });
__PACKAGE__->register_method($namespace, $method, sub { 1 });

This method performs register the new method in your namespace

By default use current application namespace

register_plugin

$app->register_plugin('foo', 'MyApp::Plugin::Foo');
$app->register_plugin('foo', 'MyApp::Plugin::Foo', {bar => 123});
$app->register_plugin('foo', 'MyApp::Plugin::Foo', bar => 123);

Load a plugin and run register method, optional arguments are passed through

run

By default this method is alias for "run_handler" method.

This method meant to be overloaded in a subclass

run_handler

my $result = $app->run_handler("foo",
    foo => "one",
    bar => 1
) or die $app->error;

Runs handler by name and returns result of it handler running

silentmode

$app->silentmode;

Returns the verbose flag in the opposite value. 0 - verbose, 1 - silent.

See "verbosemode"
