DESCRIPTION

JSON::Validator::Formats is a module with utility functions used by "formats" in JSON::Validator to match JSON Schema formats. All functions return undef for success or an error message for failure.

FUNCTIONS

check_byte

  my $str_or_undef = check_byte $str;

Checks that the string matches byte format.

check_date

  my $str_or_undef = check_date $str;

Validates the date part of a RFC3339 string.

check_date_time

  my $str_or_undef = check_date_time $str;

Validated against RFC3339 timestamp in UTC time. This is formatted as "YYYY-MM-DDThh:mm:ss.fffZ". The milliseconds portion (".fff") is optional

check_duration

  my $str_or_undef = check_duration $str;

Validate a RFC3339 duration string, such as "P3Y6M4DT12H30M5S".

check_double

  my $str_or_undef = check_double $number;

Tries to check if the number is a double. Note that this check is not very accurate.

check_email

  my $str_or_undef = check_email $str;

Validated against the RFC5322 spec.

check_float

  my $str_or_undef = check_float $number;

Tries to check if the number is a float. Note that this check is not very accurate.

check_hostname

  my $str_or_undef = check_hostname $str;

Will be validated using "is_hostname" in Data::Validate::Domain, if installed.

check_idn_email

  my $str_or_undef = check_idn_email $str;

Will validate an email with non-ASCII characters using Net::IDN::Encode if installed.

check_idn_hostname

  my $str_or_undef = check_idn_hostname $str;

Will validate a hostname with non-ASCII characters using Net::IDN::Encode if installed.

check_int32

  my $str_or_undef = check_int32 $number;

Tries to check if the number is a int32. Note that this check is not very accurate.

check_int64

  my $str_or_undef = check_int64 $number;

Tries to check if the number is a int64. Note that this check is not very accurate.

check_ipv4

  my $str_or_undef = check_ipv4 $str;

Will be validated using "is_ipv4" in Data::Validate::IP, if installed or fall back to a plain IPv4 IP regex.

check_ipv6

  my $str_or_undef = check_ipv6 $str;

Will be validated using "is_ipv6" in Data::Validate::IP, if installed.

check_iri

  my $str_or_undef = check_iri $str;

Validate either an absolute IRI containing ASCII or non-ASCII characters, against the RFC3986 spec.

check_iri_reference

  my $str_or_undef = check_iri_reference $str;

Validate either a relative or absolute IRI containing ASCII or non-ASCII characters, against the RFC3986 spec.

check_json_pointer

  my $str_or_undef = check_json_pointer $str;

Validates a JSON pointer, such as "/foo/bar/42".

check_regex

  my $str_or_undef = check_regex $str;

Will check if the string is a regex, using qr{...}.

check_relative_json_pointer

  my $str_or_undef = check_relative_json_pointer $str;

Validates a relative JSON pointer, such as "0/foo" or "3#".

check_time

  my $str_or_undef = check_time $str;

Validates the time and optionally the offset part of a RFC3339 string.

check_uri

  my $str_or_undef = check_uri $str;

Validate either a relative or absolute URI containing just ASCII characters, against the RFC3986 spec.

Note that this might change in the future to only check absolute URI.

check_uri_reference

  my $str_or_undef = check_uri_reference $str;
