Medium level API functions

compile

Arguments

:: CompOption

(summed together)

-> ExecOption

(summed together)

-> ByteString

The regular expression to compile

-> IO (Either (MatchOffset, String) Regex)

Returns: the compiled regular expression

Compiles a regular expression

execute

Arguments

:: Regex

Compiled regular expression

-> ByteString

String to match against

-> IO (Either WrapError (Maybe (Array Int (MatchOffset, MatchLength))))

Returns: Nothing if the regex did not match the string, or: Just an array of (offset,length) pairs where index 0 is whole match, and the rest are the captured subexpressions.

Matches a regular expression against a buffer, returning the buffer indicies of the match, and any submatches

| Matches a regular expression against a string

regexec

-> ByteString

String to match against

-> IO (Either WrapError (Maybe (ByteString, ByteString, ByteString, [ByteString])))
