>The <A HREF="Text-Regex-TDFA.html"
>Text.Regex.TDFA</A
> module provides a backend for regular
expressions. It provides instances for the classes defined and
documented in <A HREF="Text-Regex-Base.html"
>Text.Regex.Base</A
> and re-exported by this module.  If
you import this along with other backends then you should do so with
qualified imports (with renaming for convenience).

>This regex-tdfa package implements, correctly, POSIX extended regular
expressions.  It is highly unlikely that the regex-posix package on
your operating system is correct, see
http:<EM
></EM
>www.haskell.org<EM
>haskellwiki</EM
>Regex_Posix for examples of your
OS's bugs.
</P
><P
>This package does provide captured parenthesized subexpressions.
</P
><P
>Depending on the text being searched this package supports Unicode.
The [Char] and (Seq Char) text types support Unicode.  The ByteString
and ByteString.Lazy text types only support ASCII.  It is possible to
support utf8 encoded ByteString.Lazy by using regex-tdfa and
regex-tdfa-utf8 packages together  (required the utf8-string package).
</P
><P
>As of version 1.1.1 the following GNU extensions are recognized, all
anchors:
</P
><P
>\` at beginning of entire text
</P
><P
>\' at end of entire text
</P
><P
>\&lt; at beginning of word
</P
><P
>\&gt; at end of word
</P
><P
>\b at either beginning or end of word
</P
><P
>\B at neither beginning nor end of word
</P
><P
>The above are controlled by the <TT
><A HREF="Text-Regex-TDFA-Common.html#v%3AnewSyntax"
>newSyntax</A
></TT
> Bool in <TT
><A HREF="Text-Regex-TDFA-Common.html#t%3ACompOption"
>CompOption</A
></TT
>.
</P
><P
>Where the <A HREF="word.html"
>word</A
> boundaries means between characters that are and are
not in the [:word:] character class which contains [a-zA-Z0-9_].  Note
that &lt; and b may match before the entire text and &gt; and b may
match at the end of the entire text.
</P
><P
>There is no locale support, so collating elements like [.ch.] are
simply ignored and equivalence classes like [=a=] are converted to
just [a].  The character classes like [:alnum:] are supported over
ASCII only, valid classes are alnum, digit, punct, alpha, graph,
space, blank, lower, upper, cntrl, print, xdigit, word.
</P
><P
>This package does not provide <A HREF="basic.html"
>basic</A
> regular expressions.  This
package does not provide back references inside regular expressions.
</P
><P
>The package does not provide Perl style regular expressions.  Please
look at the regex-pcre and pcre-light packages instead.
