Examples ¶
Constants ¶
const ( // Unknown is unresolved OS type Unknown = iota // Win is Windows type Win // Unix is *nix OS types Unix )
Used by IsFilePath func
const RF3339WithoutZone = "2006-01-02T15:04:05"
Variables ¶
var ISO3166List = []ISO3166Entry{}/* 249 elements not displayed */
ISO3166List based on https://www.iso.org/obp/ui/#search/code/ Code Type "Officially Assigned Codes"
var ISO693List = []ISO693Entry{}/* 184 elements not displayed */
ISO693List based on http://data.okfn.org/data/core/language-codes/r/language-codes-3b2.json
var LocaleList = map[string]LocaleEntry{}/* 731 elements not displayed */
LocaleList contains all locales and their English names. This variable should be a private variable to prevent race conditions caused by inexperienced developers modifying a map. Only reading from a fixed sized map is race free. If you modify this map during runtime you should go straight to hell.
