Revision history for DateTime::Format::Genealogy
0.13 Sat Jul 25 17:27:13 EDT 2026
[ Bug Fixes ]
- Fix t/error.t failures when Params::Get >= 0.13 croaks before our own usage check
See https://github.com/nigelhorne/DateTime-Format-Genealogy/issues/11
- Fix 'return inside eval' bug in _convert_calendar that silently discarded
Hebrew and French Republican calendar conversions
- Fix bare clone (->new() on an object) returning the original reference
instead of a copy
- Fix ISO date month 00 silently mapping to December via Perl's negative
array-index wrap; month 13-99 no longer produces undef month name
- Fix $@ race condition: three eval blocks (validate_strict, Hebrew calendar,
French Republican calendar) now capture $@ into a lexical immediately so
a DESTROY firing between the eval and the check cannot silently clear it
- Fix greedy first-group quantifier in 'bet X and Y' / 'from X to Y' range
patterns; was picking the last keyword occurrence rather than the first
- Fix unanchored =~ /FRENCH R/ calendar-type test replaced with string
equality, preventing false matches on future escape variants
- Fix 3-digit and oversized years returning today's date instead of undef
(DateTime::Format::Natural success() was not checked in the GGD-cached path)
- Fix missing optional calendar module returning a Gregorian DateTime instead
of undef when DateTime::Calendar::Hebrew or ::FrenchRevolutionary is absent
- Fix undef canonical field in GGD result crashing DateTime::Format::Natural
[ Security ]
- Sanitise user-supplied date strings in all Carp messages via new _safe_str()
helper: control characters (including CR/LF for log injection, ANSI escapes)
are replaced with '?' and messages are truncated at 120 characters
- Add MAX_CACHE_SIZE guard (10,000 entries) in _date_parser_cached to prevent
memory exhaustion when an adversarial caller feeds unbounded unique strings
invalid string and duplicate carp emissions
- _date_parser_cached now accepts a plain positional arg instead of routing
through Params::Get, removing measurable dispatch overhead from the hot path
- _julian_to_gregorian_offset uses a for-loop with early exit instead of grep,
avoiding temporary list allocation on each Julian date conversion
[ Enhancements ]
- Support Object::Configure
- Use Params::Get in new()
- Use Params::Validate::Strict to reject unknown parameter keys
- Use Sub::Private (enforce mode) for _convert_calendar and
_julian_to_gregorian_offset; use Sub::Protected for _date_parser_cached
- Use Readonly constants for month alias table, Julian offset tiers, and
new MAX_CACHE_SIZE limit
- Consolidate French/German month aliases (Janv, Juli, Mai) into the main
%MONTH_ALIAS lookup table; remove separate special-case branches
- quiet and strict flags now fall back to object-level attributes when
not supplied per-call to parse_datetime
- Full POD added: EXAMPLE, API SPECIFICATION, MESSAGES, FORMAL SPECIFICATION,
PSEUDOCODE, and LIMITATIONS sections
- New t/locales.t covering POSIX locale behaviour
# VERSION
Version 0.13
# SYNOPSIS
`DateTime::Format::Genealogy` is a Perl module designed to parse genealogy-style
date strings (primarily GEDCOM format) and convert them into [DateTime](https://metacpan.org/pod/DateTime) objects.
It wraps [Genealogy::Gedcom::Date](https://metacpan.org/pod/Genealogy%3A%3AGedcom%3A%3ADate) and [DateTime::Format::Natural](https://metacpan.org/pod/DateTime%3A%3AFormat%3A%3ANatural), adds GEDCOM
calendar-escape handling, and accepts common non-standard month names found in
exported genealogical trees.
use DateTime::Format::Genealogy;
my $dtg = DateTime::Format::Genealogy->new();
my $dt = $dtg->parse_datetime('25 Dec 2022');

RETURN bless(params, class)
END FUNCTION
## parse\_datetime
Parses a genealogy-style date string and returns a [DateTime](https://metacpan.org/pod/DateTime) object.
Recognises GEDCOM calendar escapes (`@#DJULIAN@`, `@#DHEBREW@`,
`@#DFRENCH R@`) and converts them via the appropriate calendar module when
available.
Can be called as a class method, an object method, or a bare function.
Returns:
- A single [DateTime](https://metacpan.org/pod/DateTime) object for exact, parseable dates.
- A two-element list of [DateTime](https://metacpan.org/pod/DateTime) objects in _list_ context when the date
string is a range (`bet X and Y` / `from X to Y`).
- `undef` (scalar) or the empty list (list context) when the date cannot be
my $dtg = DateTime::Format::Genealogy->new();
# Simple exact date
my $dt = $dtg->parse_datetime('25 Dec 2022');
print $dt->dmy; # 25-12-2022
# Date range (list context)
my ($start, $end) = $dtg->parse_datetime('bet 1 Sep 1939 and 2 Sep 1945');
# GEDCOM calendar escape
my $julian = $dtg->parse_datetime('@#DJULIAN@ 15 Mar 1620');
# Class-method form (no constructor required)
my $dt2 = DateTime::Format::Genealogy->parse_datetime('1 Jan 2000');
# Long month name (non-strict only)
my $dt3 = $dtg->parse_datetime('12 June 2020');
# French month variant (non-strict only)
my $dt4 = $dtg->parse_datetime('21 Mai 1681');
- `Unparseable date $date - often because the month name isn't 3 letters`
Warned (carp) in strict mode for non-3-letter months, or in non-strict mode
for unrecognised long month names. Silenced by `quiet`.
- `$dfn_error_string`
Warned (carp) when [DateTime::Format::Natural](https://metacpan.org/pod/DateTime%3A%3AFormat%3A%3ANatural) rejects the date string.
Silenced by `quiet`.
- `Hebrew calendar conversion failed: ...`
Warned (carp) when [DateTime::Calendar::Hebrew](https://metacpan.org/pod/DateTime%3A%3ACalendar%3A%3AHebrew) is unavailable or throws.
Silenced by `quiet`.
- `French Republican calendar conversion failed: ...`
Warned (carp) when [DateTime::Calendar::FrenchRevolutionary](https://metacpan.org/pod/DateTime%3A%3ACalendar%3A%3AFrenchRevolutionary) is unavailable
or throws. Silenced by `quiet`.
- `Calendar type $type not supported`
Warned (carp) for GEDCOM calendar escapes other than GREGORIAN, JULIAN,
HEBREW, and FRENCH R. Silenced by `quiet`.

rc = DateTime::Format::Natural->parse_datetime(date)
IF rc AND success: RETURN rc
ELSE: CARP error
RETURN undef
END FUNCTION
# LIMITATIONS
- Dates before AD 100 are rejected because [DateTime::Format::Natural](https://metacpan.org/pod/DateTime%3A%3AFormat%3A%3ANatural) cannot
parse them reliably (it returns today's date instead of an error).
- The `Aout` (French August with circumflex-u) entry in the month-alias table
uses a non-ASCII Unicode escape (`\x{FB}`). The module file must be read as
UTF-8; this is satisfied by the standard `perl -Ilib` invocation but may
require `use utf8` or `open ':encoding(UTF-8)'` in unusual environments.
- Hebrew and French Republican calendar conversions require
[DateTime::Calendar::Hebrew](https://metacpan.org/pod/DateTime%3A%3ACalendar%3A%3AHebrew) and [DateTime::Calendar::FrenchRevolutionary](https://metacpan.org/pod/DateTime%3A%3ACalendar%3A%3AFrenchRevolutionary)
respectively. These are optional and not listed as hard dependencies. When
absent, the GEDCOM escape is silently discarded and undef is returned unless
the `quiet` flag is off, in which case a carp is emitted.
- [Genealogy::Gedcom::Date](https://metacpan.org/pod/Genealogy%3A%3AGedcom%3A%3ADate) cannot parse native Hebrew or French Revolutionary
month names (e.g. `Tishri`, `Vendemiaire`). Only dates written in
Gregorian form with the `@#DHEBREW@` escape are converted.
- The `quiet` and `strict` flags may be set at construction time
(`->new(quiet => 1)`) and will be respected by all subsequent calls to
`parse_datetime` unless overridden on a per-call basis. The per-call value
