Overview ¶

Package i18n provides lightweight internationalization for the DWS CLI.

At startup call Init() (or let the package auto-init via the init function). Use T("key") to get a translated string, or Tf("key", args...) for formatted translations with fmt.Sprintf-style placeholders.

The active language is resolved from the DWS_LANG environment variable first, then falls back to the LANG environment variable. If neither is set or does not match a supported locale, "en" (English) is used as the default.

Message catalogs are stored as JSON files under locales/ and embedded at compile time via go:embed.

Supported locales:

"en" — English (default)
"zh" — Simplified Chinese

Functions ¶

func Init ¶

func Init()

Init resolves the active locale from environment variables and loads the message catalogs from embedded JSON files. Safe to call multiple times; only the first call takes effect.

func Lang ¶

func Lang() string

Lang returns the current language tag string ("en" or "zh").

func LangTag ¶

func LangTag() language.Tag

LangTag returns the resolved language.Tag.

func SetLang ¶

func SetLang(tag string)

SetLang overrides the active locale. Intended for testing.

func T ¶

func T(key string) string

T returns the translated string for the given message key. If the key is not found in the active catalog, the key itself is returned.

func Tf ¶

func Tf(key string, args ...any) string

Tf returns a formatted translated string. The key is looked up in the active message catalog and the result is passed through fmt.Sprintf with the provided arguments.
