NAME
Date::Manip::Lang - language support for Date::Manip
DESCRIPTION
Date::Manip supports a number of different languages when parsing dates,
and more can be added.
CURRENT LANGUAGES
Currently, the following languages are supported by Date::Manip. The
version of Date::Manip where they were added is included (so you can see
the minimum version of Date::Manip needed to parse each).
The language can be chosen by setting the Language config variable to the
name of the language or any of the aliases included in the table.
All names and aliases are case insensitive.

ADDING A LANGUAGE
Adding a language is easily done (if you're fluent in both English and
the other language). If you want to add a new language, do the
following:
Language name
When you submit the new language, I'll need the name of the language
(of course) and any common locale names that might be useful for
people to select the language.
For example, if you were creating a Spanish translation (which is not
necessary since it already exists), I would need the following list:
spanish es es_es
Copy the english module
Copy the english.pm file (which is in lib/Date/Manip/Lang in the
Date::Manip distribution) to the new language (i.e. spanish.pm in
this example).
Set some variables in the new module
The new module (spanish.pm) will need a few simple modifications.
Change the package name from 'english' to 'spanish'.
Fix the @Encodings lines. Most languages can be written in more than
one encoding. The first encoding in the list should be utf-8 and the
last should be perl. Include any other encodings that should be
supported as well.
Set the $YearAdded and $LangName appropriately.
Translate the language terms
The data section of the module is fairly straightforward to
translate.
Every term is defined in the Date::Manip::Lang::english document (or
in any of the other language module documents), so please refer to it
to find out what each element means. Then replace the English
version with the new translation.
There are some requirements:
1) Every element should be defined (except for the sephm and sepms
elements which are optional).
2) The module must be written using UTF-8 characters if the language
includes any non-ASCII characters.
3) Each element includes a list of values (different variations of
the element). In most cases, the order of the values for each
element is not important since they are just used to create a regular
expression for parsing dates, but a few of them are also used to
determine printable values using the "Date::Manip::Date::printf"
method (or the "UnixDate" function). These elements are:
Element printf directive
ampm %p
day_abb %a
day_char %v
day_name %A
month_abb %b
month_name %B
nth %E
For each of these, the value that should be printed out must be the
first value in the list.
4) When possible, if a language includes characters that are
essentially ASCII characters with a punctuation mark, please include
a variation of the value which is just ASCII with the punctuation
removed. For example, the spanish name for Saturday in ASCII would
be written sabado, but in reality, the first 'a' has an accent over
it. This word should appear twice... first in full UTF-8 encoding,
and second as all ASCII. If the language (Russian for example) has no
ASCII equivalent, just include the UTF-8 representation.
Feel free to contact me if you have any questions.
LANGUAGE SPECIFIC RULES
In the language file, there is one special value named _special_rules.
This is a hash of special parsing rules that will be applied for this
language.
Currently the following rules are available:
remove_trailing_period
If this is set, trailing periods will be removed.
For example, in German, default output of the date command includes a
day of month with a trailing period. For example:
Mo 3. Jan 11:00:00 EST 2022
If this rule is set, periods followed by whitespace (or an end of
string) are stripped.
remove_parens
This will strip parentheses () from a string.
strip_word
This is a list of words that will be stripped from a string. Each
word must be bracketed by the start/end of the string or whitespace.
