find-locale

Arguments: name

name can be a locale or a string naming a locale or a symbol (in which case, the symbol-name is used) or a locale. If name is a locale, then name is returned.

If name is a string designator, then this function looks through all locales returned by all-locales to find a locale whose locale-name matches (i.e., is equalp to) name. If one such locale is found, it is returned.

If no such locale is found, then if the name includes a charset specification (i.e., has a period followed by a charset name), then the charset specification is passed to find-external-format and a base-locale is retrieved by calling find-locale recursively on name with the charset specification stripped. If both the charset specification names an external-format and the base-locale is a valid locale, then this function creates a new locale using all the slots of base-locale except for the external-format slot, which is set to the external-format corresponding to the specified charset.

If name does not specify a charset and it does not name an existing locale in Lisp, then this function searches the directory specified by *locales-dir* for a file with name's pathname-name and calls load-localedef on that pathname. If no such file exists with name's pathname-name, then a file in that directory whose name's prefix matches name may be selected. This search is case-sensitive. In this way, Allegro CL autoloads locale definitions.

If no locale or suitable file is found, nil is returned.

Examples:

(find-locale "pl")
  -> #<locale "pl_PL" [(:e-crlf :iso8859-2-base)] @ #x204de7ca>
(find-locale "en_US")
  -> #<locale "en_US" [(:e-crlf :latin1-base)] @ #x204e5812>
(locale-external-format (find-locale "en_US.iso8859-1"))
  -> #<external-format (:e-crlf :latin1-base) @ #x20096d02>
(locale-external-format (find-locale "en_US.shiftjis"))
  -> #<external-format (:e-crlf :shiftjis-base) @ #x2053dde2>
