=head1 NAME
TOML::Parser - simple toml parser
=head1 SYNOPSIS
use TOML::Parser;
my $parser = TOML::Parser->new;
my $data = $parser->parse($toml);
=head1 DESCRIPTION
TOML::Parser is a simple toml parser.
This data structure complies with the tests
provided at L<https://github.com/toml-lang/toml/tree/v0.4.0/tests>.
The v0.4.0 specification is supported.
=head1 METHODS
=over
=item my $parser = TOML::Parser->new(\%args)
Creates a new TOML::Parser instance.
use TOML::Parser;
# create new parser
my $parser = TOML::Parser->new();
Arguments can be:
=over
=item * C<inflate_datetime>
If use it, You can replace inflate C<datetime> process.
The subroutine of default is C<identity>. C<e.g.) sub { $_[0] }>
use TOML::Parser;
use DateTime;
use DateTime::Format::ISO8601;
# create new parser
my $parser = TOML::Parser->new(
inflate_datetime => sub {
my $dt = shift;
return DateTime::Format::ISO8601->parse_datetime($dt);
},
);
=item * C<inflate_boolean>
If use it, You can replace inflate boolean process.
The return value of default subroutine is C<Types::Serialiser::true> or C<Types::Serialiser::false>.
use TOML::Parser;
# create new parser
my $parser = TOML::Parser->new(
inflate_boolean => sub {
my $boolean = shift;
return $boolean eq 'true' ? 1 : 0;
},
);
=item * C<strict_mode>
TOML::Parser is using a more flexible rule for compatibility with old TOML of default.
If make this option true value, You can parse a toml with strict rule.
use TOML::Parser;
# create new parser
my $parser = TOML::Parser->new(
strict_mode => 1
);
=back
=item my $data = $parser->parse_file($path)
=item my $data = $parser->parse_fh($fh)
=item my $data = $parser->parse($src)
Transforms a string containing toml to a perl data structure or vice versa.
