Replaced remaining tabs within the entire source with regular spaces (4).

0.62_02 Thu Dec 13 12:12:06 CET 2007

Localized $1 within the grammar parser (i.e., the method _process()) before examining whether a regular expression succeeded and if it did, check whether it did capture some content and save it on the "regex-stack".
Enhanced the diagnostic printed when faulty grammar types are encountered.
Changed a type definition from 'SCALAR' to 'REGEXP' within EN.pm.

0.62_01 Tue Dec 11 13:28:31 CET 2007

No "functional" changes, merely "cosmetic" ones.

0.62 Mon Dec 3 21:06:05 CET 2007

Added support for abbreviated week-/monthnames when 'prefer_future' option is enabled. [rt #31254 - Shawn M. Moore <sartak@gmail.com>]
Deprecated export of subs within Lang/Base.pm to Lang/EN.pm (the ISA relationship is sufficient).

0.61 Sat Nov 24 10:32:31 CET 2007

Improved code efficiency a bit & removed some dead code.

0.60 Tue Nov 20 16:59:24 CET 2007

Major redo of flexible language metadata handling.

0.40 Sun Sep 23 17:34:48 CEST 2007

Empty the marked tokens list on each instance of parse_datetime()/ parse_datetime_duration().

0.38_01 Tue Sep 4 18:10:48 CEST 2007

Undone use'ing constant with a hashref provided (breaks on older versions of Perl [testers #598724 - David Cantrell <david@cantrell.co.uk>]).

Implemented next [monthname] & last [monthname] parsing and added according tests. [Shawn M. Moore <sartak@gmail.com>]
Added tests for the constant daytime values.
Albeit it's unlikely that someone will ever subclass Lang/Base.pm, a bug in the statement involving bless() within the constructor has been fixed (ref($class) 'check' must come first, otherwise subclassing is impossible).
scripts/dateparse is now being installed.

0.34 Sun May 20 17:09:09 CEST 2007

Hopefully fixed "Type of arg 1 to List::MoreUtils::any must be block or sub {} (not list)" errors.
Added initcheck() which is being called by _init() to validate the options passed to the constructor new().

0.33 Sat May 19 03:08:29 CEST 2007

Got mostly rid of the "no warnings 'uninitialized'" statements and ensured that no undefined values will be encountered by introducing an according token accessor which will return either a reference to an existing token or to a defined string (in case a token does not yield any defined value).
Disallowed 'am/pm' for german language metadata since they're not known to a native german speaker assuming it is referred to the german language itself. [Urs Stotz <stotz@gmx.ch]
Introduced two methods, success() and error(). Former indicates whether the parsing of a date/time string succeeded or not; latter provides the error string if former one should fail. Furthermore, the entire system is now reliant upon both of them and doesn't croak any longer if parsing should fail.
Added according getter/setter/unsetter accessors for the internal error and failure attributes.

0.32 Thu May 10 23:52:00 CEST 2007

Replaced some conditional variables with early return statements.
Introcuded Date::Calc's check_date() and check_time() to assure for integrity of date/time values submitted to according setter methods.
Wrapped check_date() and check_time() in subs which croak upon error and supply the type of value and the actual value in the message delivered to the caller, otherwise return true.
Separated datetime_parse_duration() logic from datetime_parse() and added according documentation [Cory Watson <jheephat@gmail.com>]

0.31 Sun May 6 02:57:13 CEST 2007

Replaced undef on hash elements within Natural/Base.pm with delete.
Changed 'time_zone' parameter's value in calls to DateTime->now() with 'floating' instead of 'local'. This should function as fix to failures reported on MSWin & Cygwin platforms according to [Dave Rolsky <urth@autarch.org>].
Due to an unlocalized signal warning handler, uninitialized warnings in code which either required/use'd DateTime::Format::Natural were being supressed. The handler has been commented out (and left in for debugging/development purpose) and replaced by an according 'no warnings' statements in both Natural.pm & Natural/Base.pm.

0.30 Sun Apr 29 02:33:16 CEST 2007

Fixed some spurious date results assumptions in t/01-parse_en.t and t/02-parse_de.t which were caused by a bug.
Extended documentation to include options pertaining to method calls within the documentation in listed form.

Modified scripts/dateparse.pl to return a absolute time with precision in seconds.

0.28 Wed Apr 11 01:44:49 CEST 2007

Moved timespan separator definition to language metadata base classes.
scripts/dateparse.pl language chosen always defaulted to 'en' irrespective whether another one has been chosen or not. Changed it to only fallback to the default language ('en') if no other one has been provided.
Added t/03-parse_format.t to the testsuite which tests datestrings with various differing format strings.

0.27 Tue Apr 10 22:19:15 CEST 2007

Mentioning Tatsuhiko Miyagawa as the inspiration source in the documentation's Credits section.
Implemented a simple timespan calculation, provided the natural dates are separated by the literal token 'to' (case-insensitive). [Mark Stosberg <mark@summersault.com>]

0.26 Wed Mar 14 13:15:07 CET 2007

The constructor accepts now an optional 'format' parameter specifying in which format numeric dates should be parsed (either / or - may be used to separate the units). [mike <pulsation@gmail.com>]

0.25 Sun Mar 11 23:02:45 CET 2007

Separated the logic within parse_datetime() to _process() and according internal subroutines.
Commented the majority of functions within Base.pm.
Introduced List::MoreUtils' any() & none() functions; deprecated use of 'no warnings' statement which need arose by accessing indexes of @{$self->{tokens}} where no members were present.
Created TODO file with pending items.

0.24 Wed Jan 17 22:51:51 CET 2007

Introduced a warning handler to silence the warnings about undefined values when pattern matching, subtracting and performing string comparisons in Natural/Base.pm.
Merged the "frontend" scripts to a single one taking optionally a language argument indicating the country code among other arguments.
Made 01-parse_en.t's & 02-parse_de.t's code more readable by adding some more separating lines.
Moved 'our' declarations in DE.pm & EN.pm towards the top.

0.23 Tue Jan 16 19:51:50 CET 2007

The language metadata classes have an AUTOLOAD handler & __new constructor automatically exported to their namespaces. Because some local fiddling with AUTOLOAD and dynamic variable lookup is done, a bunch of symbolic references are created on-the-fly.

0.22 Tue Jan 16 02:58:15 CET 2007

Previously four digits were occasionally interpreted as year and as well as time based upon context. Disambiguated usage as year (applies to all Lang:: classes) and fixed all test cases were bogus return values from parse_datetime() have been expected in order to have no tests fail.
Bound the temporary disablement of strictness for references to a tighter scope (applies to all Lang:: classes).

0.21 Tue Nov 28 09:31:20 CET 2006

Corrected the classes names provided to use_ok() in 00-load.t. [SEKIMURA sekimura@gmail.com]

Optimised the regular expressions used in the AUTOLOAD routine in the language classes.

0.19 Mon Nov 27 20:06:17 CET 2006

Added to DE.pm & EN.pm an AUTOLOAD handler for each of them. The subroutine called prefixed with two underscores will be translated to an according variable name without underscores. The parameter to the subroutine will function as variable lookup key.

0.18 Sun Nov 26 17:35:17 CET 2006

Fixed all occurences of the global weekday hash by adding the missing key "{data}" to the variable lookup.

0.17 Sun Nov 26 16:50:14 CET 2006

Encapsulated the metadata within the language packages in an object which class gets subclassed from Natural.pm. [Tatsuhiko Miyagawa <miyagawa@gmail.com>]

0.16 Sat Nov 25 18:09:48 CET 2006

Added missing '1;' to the documentation of Authoring.pod.

0.10 Thu Nov 23 01:14:44 CET 2006

Substituted additions/subtractions where possible with the appropriate DateTime method calls.
An Exception is thrown if no valid input has been given. [Tatsuhiko Miyagawa <miyagawa@gmail.com>]

0.09 Sun Nov 19 14:38:24 CET 2006

Date strings with slashes are now being split and assigned to the appropriate variables.
Moved the initialization of object data into a sub. Same procedure for the code chunk returning a datetime object.

0.08 Sun Nov 19 12:30:24 CET 2006

Code is now object-oriented.

0.07 Sat Oct 28 17:16:53 CEST 2006

Replaced all tabs in EN.pm with regular spaces (4).

0.06 Wed Oct 25 20:24:38 CEST 2006

Substituted exporting functions with an object-oriented constructor. parse_datetime() is now called as a method. [Dave Rolsky <urth@autarch.org>]
parse_datetime() takes either a datestring or an options hash. [Dave Rolsky <urth@autarch.org>]
