Miscellaneous

2 declarations

valueunusedOffset :: MatchOffset

valuegetVersion :: Maybe String

Version string of PCRE library

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

Medium level API functions

3 declarations

valuecompile

:: CompOption
Flags (summed together)
-> ExecOption
Flags (summed together)
-> Seq Char
The regular expression to compile
-> IO (Either (MatchOffset, String) Regex)
Returns: an error string and offset or the compiled regular expression

Compiles a regular expression

valueexecute

:: Regex
Compiled regular expression
-> Seq Char
(Seq Char) 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 string

valueregexec

:: Regex
compiled regular expression
-> Seq Char
string to match
-> IO (Either WrapError (Maybe (Seq Char, Seq Char, Seq Char, [Seq Char])))
Returns: Nothing if no match, else (text before match, text after match, array of matches with 0 being the whole match)

execute match and extract substrings rather than just offsets
