Summary
There is a class named CULTURE_INFO in "mscorlib" in EiffelStudio, which provides information about a specific culture such as:
- associated language
- sublanguage
- country/region
- calendar
- cultural conventions
Listing available locales
I didn't find a function that returns all the available locale informations, I think because under .NET, they are all avaiable.
Checking for default locale
Retrieving locale information
To obtain informations on a specific locale, it suffices to create an instance of CULTURE_INFO. There are basically two ways to do this:
- Create it with the culture identifier. This identifier maps every culture/language to an integer. It is not very usefull, because I did not find a logic behind the mapping function... You can find a table on here
- Create it with the name (STRING) of the culture. The culture names follow the RFC 1766 standard in the format "<languagecode2>-<country/regioncode2>", where <languagecode2> is a lowercase two-letter code derived from ISO 639-1 and <country/regioncode2> is an uppercase two-letter code derived from ISO 3166.
You can find a detailed description of RFC 1766
The CULTURE_INFO Class has some attibutes useful for the retrieving of the informations about Date, Time and Number formatting, they are:
- date_time_format: DATE_TIME_FORMAT_INFO (see here)
| Information | Result for locale "it-CH" |
|---|---|
| full_date_time_pattern | dddd, d. MMMM yyyy HH:mm:ss |
| long_date_pattern | dddd, d. MMMM yyyy |
| long_time_pattern | HH:mm:ss |
| month_day_pattern | d. MMMM |
| rfc1123_pattern | ddd, dd MMM yyyy HH':'mm':'ss 'GMT' |
| pm_designator | |
| short_date_pattern | dd.MM.yyyy |
| short_time_pattern | HH:mm |
| sortable_date_time_pattern | yyyy'-'MM'-'dd'T'HH':'mm':'ss |
| time_separator |
- there are also functions that return abbreviations of names of months and day:
- get_abbreviated_day_name (dayofweek: DAY_OF_WEEK) : SYSTEM_STRING
- get_abbreviated_month_name (month: INTEGER) : SYSTEM_STRING
- number_format: NUMBER_FORMAT_INFO (see here)
| Information | Result for locale "it-CH" |
|---|---|
| currency_group_separator | ' |
| currency_symbol | SFr. |
| currency_decimal_digits | 2 |
| negative_sign | - |
| number_decimal_digits | 2 |
| number_decimal_separator | . |
| number_group_separator | ' |
| positive_sign | + |
| negative_sign | - |
| negative_infinity_symbol | -Infinito |
| per_mille_symbol | ë |
| na_n_symbol | Non un numero reale |
