validate and match using redis globs

validate :: ByteString -> Maybe ByteString

Confirm that a glob pattern is valid

the result is: - Nothing when the pattern is invalid - Just norm, where norm is a normalized version of the pattern

Examples

>>> validate "hel?o"
Just "hel?o"

>>> validate "hel[i-m]o"
Just "hel[i-m]o"

>>> validate "hell[i-]o"
Nothing

matches :: ByteString -> ByteString -> Bool

Confirm that a target ByteString matches the pattern defined by another.

the result is: - False when the pattern is invalid or does not match target - otherwise it's True

Examples

>>> "hello" `matches` "hel?o"
True

>>> "hello world" `matches` "[^m-z]el[i-m]o w*"
True

>>> "yello world" `matches` "[^m-z]el[i-m]o w???d"
False
