    ds.xml Validator case sensitivity (Question or Enhancement)

    Hi Isomorphic,

    I have this simple type I'm using for my eMail fields:
    Code:
    <SimpleType name="emailType" inheritsFrom="text">
                <validators>
                    <validator type="regexp"
                        expression="^[a-zA-Z0-9._%+-]+@(?:[a-zA-Z0-9-]+\.)+(?:[a-zA-Z]{2}|[cC][oO][mM]|[oO][rR][gG]|[nN][eE][tT]|[eE][dD][uU]|[gG][oO][vV]|[mM][iI][lL]|[bB][iI][zZ]|[iI][nN][fF][oO]|[mM][oO][bB][iI]|[nN][aA][mM][eE]|[aA][eE][rR][oO]|[aA][sS][iI][aA]|[jJ][oO][bB][sS]|[mM][uU][sS][eE][uU][mM])$">    
                    </validator>
                </validators>
    </SimpleType>
    It's a simple email-address validation, which now fails for the ".berlin" TLD.
    Of course I know the regex rants
    Some people, when confronted with a problem, think
    I know, I'll use regular expressions. Now they have two problems.
    but still, if the lists gets longer and I wanted to validate against the IANA list of domains, I need it to be case insensitive - and working in serverside Java and JavaScript.

    In Java, this would be done like this (docs), or with the also supported modifier-parameter.
    Code:
    expression="[B](?i)[/B]^[a-zA-Z0-9._%+-]+@(?:[a-zA-Z0-9-]+\.)+(?:[a-zA-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)$"
    But this leads to this stack trace on the client (v10.1p_2016-08-26, FF26 Dev mode):
    Code:
    11:44:14.760 [ERROR] [lms] 11:44:14.759:TMR9:WARN:Log:SyntaxError: invalid quantifier

    So my question is how to make this work in both environments, as JavaScript does not support inline modifiers?

    My suggestion would be a modifier-attribute for type="regexp"-valdidators. This would work in Java and JavaScript.
    I'm using 5.1 now, but will switch to 6.0 soon.

    Thank you & Best regards

    You previously asked for this and we noted it. Sorry, it hasn't been implemented yet, as it's rare use case that a regex will handle cleanly but where control over case-sensitivity is also required

      Hi Isomorphic,

      thanks, I already had forgotten about that thread because it was a different use case.
      I'll wait for it to be implemented, then.

      For my TLD-usecase I did the character range trick again. It makes the validator pretty big, but once I got to enable caching for the DataSourceLoader result, this won't matter anymore.

      Best regards
      Blama
