For example, the string "<tt>Re: </tt>" is commonly prepended to the subject to denote a reply. </p> <p>SUBJECTREPLYRXP is used by MHonArc for sorting and threading purposes. The regex defined is used in <b><tt>s///</tt></b> operation loops with the case-insensitive modifier. Hence, the regex should eventually fail if called repeatedly on the same string in an <b><tt>s///</tt></b> operation. If not, an infinite loop will result. In sum, SUBJECTREPLYRXP should <strong>NOT</strong> be able to match the null string. Also, the regex should be anchored to the beginning of the string. </p> <p>The SUBJECTREPLYRXP is normally changed to suit a particular locale or if unusual notations are being used to denote replies. </p> <!-- *************************************************************** --> <hr> <h2><a name="default">Default Setting</a></h2> <pre> ^\s*(re|sv|fwd|fw)[\[\]\d]*[:>-]+\s* </pre> <!-- *************************************************************** --> <hr> <h2><a name="rcvars">Resource Variables</a></h2> <p>N/A </p> <!-- *************************************************************** --> <hr> <h2><a name="examples">Examples</a></h2> <p>None. </p> <!-- *************************************************************** --> <hr> <h2><a name="version">Version</a></h2> <p>2.2.0 </p> <!-- *************************************************************** --> <hr> <h2><a name="seealso">See Also</a></h2> <p> <a href="subjectarticlerxp.html">SUBJECTARTICLERXP</a> </p> <!-- *************************************************************** --> <hr> <!--x-rc-nav--> <table border=0><tr valign="top"> <td align="left" width="50%">[Prev: <a href="subjectheader.html">SUBJECTHEADER</a>]</td><td><nobr>[<a href="../resources.html#subjectreplyrxp">Resources</a>][<a href="../mhonarc.html">TOC</a>]</nobr></td><td align="right" width="50%">[Next: <a href="subjectstripcode.html">SUBJECTSTRIPCODE</a>]</td></tr></table> <!--/x-rc-nav--> <hr> <address> $Date: 2003/10/06 22:04:20 $ <br> <img align="top" src="../monicon.png" alt=""> <a href="http://www.mhonarc.org/" ><strong>MHonArc</strong></a><br> Copyright © 1998, <a href="http://www.earlhood.com/" >Earl Hood</a>, <a href="mailto:mhonarc%40mhonarc.org" >mhonarc<!-- -->@<!-- -->mhonarc.org</a><br> </address> </body> </html>
