module Text.Regex.Posix.String
regex-posix Text.Regex.Posix.String
This provides String instances for RegexMaker and RegexLike based on Text.Regex.Posix.Wrap, and a (RegexContext Regex String String) instance. To use these instance, you would normally import Text.Regex.Posix. You only need to import this module to use the medium level API of the compile, regexec, and execute functions. All of these report error by returning Left values instead of undefined or error or fail.
module Text.Regex.Posix.ByteString
regex-posix Text.Regex.Posix.ByteString
This provides ByteString instances for RegexMaker and RegexLike based on Text.Regex.Posix.Wrap, and a (RegexContext Regex ByteString ByteString) instance. To use these instance, you would normally import Text.Regex.Posix. You only need to import this module to use the medium level API of the compile, regexec, and execute functions. All of these report error by returning Left values instead of undefined or error or fail. The ByteString will only be passed to the library efficiently (as a pointer) if it ends in a NUL byte. Otherwise a temporary copy must be made with the 0 byte appended.
