I am pretty sure I could write a wrapper and set the .setFailAction() / .setParseAction(), but I am trying to see if there is a cleaner way.</p> <p>What I am trying to accomplish is to have a string that I parse, but I want to be able to report back to the user why it failed, or why it parsed it as it did, or warnings that do not generate failures...</p> <p>so, with the following addresses, return the following flags:</p> <table> <thead> <tr> <th>Address</th> <th>Flags</th> </tr> </thead> <tbody> <tr> <td>'dan.strohl'</td> <td>ERR_NO_AT_SYMBOL, ERR_NO_DOMAIN</td> </tr> <tr> <td>'dan@strohl'</td> <td>WARN_SINGLE_DOMAIN_ELEMENT, WARN_NO_TLD</td> </tr> <tr> <td>'dan@(neat name strohl).com'</td> <td>CONTAINS_COMMENT, ERR_DONAIN_STARTS_WITH_DOT</td> </tr> <tr> <td>'dan@<span>[127.0.0.1]</span></td> <td>WARN_LOOPBACK_ADDRESS_LITERAL</td> </tr> </tbody> </table> <p>As I said, I am sure I could do something using the setFailAction that saves flags to a ceneral list, but is there a better approach? </p></div>Dan StrohlWed, 17 Feb 2016 20:57:33 -0000https://sourceforge.net7c8b5b08d57bf2972c64fc72a9c49b07254a2b1f
