Namespace Miloun.Cosmo

Classes

CollationOptions

Collation tailoring, mirroring the other ports' collation option bag.

Cosmo

Cosmo — application localisation for .NET.

A thin, ergonomic layer over ICU (reached through the native ICU4C library). It bundles no locale data of its own — every result comes straight from ICU. Construct once per locale and reuse.

A few ICU4J features have no ICU C binding and therefore throw CosmoUnsupportedException: PersonName(IDictionary<string, string>, string, string) (needs ICU 73+), IndexBuckets(IEnumerable<string>) (AlphabeticIndex is C++-only), BestMatch(IEnumerable<string>) / negotiated FromAcceptLanguage(string, IEnumerable<string>) (no C LocaleMatcher), and SupportedValues("unit").

CosmoArgumentException

A caller passed an invalid argument — an unknown currency code, an unsupported width/unit, a bad enum value, and so on.

CosmoException

Base exception for Cosmo. Catch this to handle any library error; catch a subclass to distinguish the cause.

The underlying ICU build exposes no API for the requested operation. Environmental, not a caller bug — and on the C API a few ICU4J features (person names, alphabetic index, CLDR-distance matching) simply have no C binding.

Modifiers

Optional overrides resolved at construction: calendar, currency and timeZone. Any field may be null (meaning "derive from the locale, or unavailable").

NumberOptions

Portable number-formatting controls, mirroring the option bag the other Cosmo ports accept. Any property left null keeps ICU's default.

Subtags

Parsed language / script / region subtags of a locale. Empty when absent.

WeekInfo

Week conventions for a locale's region. Days use ISO-8601 numbering (1 = Monday … 7 = Sunday), matching the JS port's Intl convention.
