Variables ¶
var ForcedRules = []Rule{ {"forced", true}, {"foreign", true}, }
ForcedRules is the declarative table for forced/foreign-parts classification. All entries are positive (any match confirms forced status).
var HearingImpairedRules = []Rule{ {"hi remove", false}, {"non hi", false}, {"nonhi", false}, {"non-hi", false}, {"non-sdh", false}, {"non sdh", false}, {"nonsdh", false}, {"sdh remove", false}, {"_hi_", true}, {" hi ", true}, {".hi.", true}, {"_cc_", true}, {" cc ", true}, {".cc.", true}, {"sdh", true}, {"closed caption", true}, }
HearingImpairedRules is the declarative table for HI/SDH/CC classification. Negative entries (Polarity=false) deny HI status and take precedence over positive entries. The first matching entry determines the result.
var LangNameToISO2 map[string]string
LangNameToISO2 is the reverse of LangRegistry: English name → ISO-2 code. Built once at init time from LangRegistry.
var LangRegistry = map[string]string{

}
LangRegistry is the canonical ISO 639-1 → English language name mapping. Provider sub-packages use this as the single source of truth, applying per-provider overrides only for non-standard names (e.g. "Brazillian Portuguese" for SubSource API compat).
Functions ¶
func Alpha2FromAlpha3 ¶
Alpha2FromAlpha3 converts an ISO 639-2/3 code to ISO 639-1. Returns the input unchanged if it is already 2 characters. Returns empty string if the code is unknown.
func IsForced ¶
IsForced returns true if the comment string indicates a forced or foreign-parts subtitle track.
func IsHearingImpaired ¶
IsHearingImpaired reports whether commentary or a filename indicates a hearing-impaired / SDH / closed-caption subtitle. A filename containing "_hi_" short-circuits to true regardless of commentary. Negative rules ("non hi", "non sdh", etc.) win over positive ones. The filename is optional: providers without a filename field should pass "".
func LookupLangCode ¶
LookupLangCode returns the ISO-2 code for an English language name, applying provider-specific overrides if provided. Returns empty string if the name is unknown.
func LookupLangName ¶
LookupLangName returns the English language name for an ISO-2 code, applying provider-specific overrides if provided. Returns empty string if the code is unknown.
func SanitizeImdbID ¶
SanitizeImdbID strips the "tt" prefix and leading zeros from an IMDB ID, returning the bare numeric string expected by most subtitle APIs.
