Miscellaneous

unusedOffset :: MatchOffset Source #

getVersion :: Maybe String Source #

Version string of PCRE library

NOTE: The Maybe type is used for historic reasons; practically, getVersion is never Nothing.

Medium level API functions

compile Source #

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 Source #

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 Source #

:: Regex	Compiled regular expression
-> ByteString	String to match against
-> IO (Either WrapError (Maybe (ByteString, ByteString, ByteString, [ByteString])))
