ensure-directories aka create-directories Lassi Kortela 31 Jul 2020 10:46 UTC
SRFI 170 is missing one of the most useful (and commonly missing, and tricky/error-prone to manually implement) OS procedures: (ensure-directory "foo") * Create directory "foo" while also creating any missing parent directories. * If "foo" already exists and is a directory, silently succeed. * If "foo" (or one of its parents) already exists but is not a directory, raise an exception. * On file system error, raise an exception as usual.
