Miscellaneous

getVersion :: Maybe String Source #

Version string of PCRE2 library

Medium level API functions

compile Source #

Arguments

:: CompOption

Flags (summed together)

-> MatchOption

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

execute Source #

Arguments

:: 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

regexec Source #

Arguments

:: 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

CompOption flags

MatchOption flags, new to v1.0.0.0 (pcre2), replacing the obsolete ExecOptions
