<jsp:directive.include file="../fragments/mason-init.jspf"/>
<m:resource>
  <m:request method="GET" item="false">
    <c:if test="${mtgReq.params['authType'] eq 'normal'}">

      <sql:query var="user" dataSource="${datasource}">SELECT * FROM account WHERE email=?
           <sql:param value="${mtgReq.params['email']}"/>
       </sql:query>
       <c:set target="${output}" property="user" value="${pageScope['user']}"/>
    </c:if>
    <c:if test="${mtgReq.params['authType'] eq 'google'}">
      <sql:query var="googleUser" dataSource="${datasource}">SELECT * FROM account WHERE email=?
      <sql:param value="${mtgReq.params['email']}"/>
      </sql:query>
      <c:set target="${output}" property="googleUser" value="${pageScope['googleUser']}"/>
    </c:if>
</m:request>
</m:resource>

Instead of above it should be

<jsp:directive.include file="../fragments/mason-init.jspf"/>
<m:resource>
  <m:request method="GET" item="false">
    <c:if test="${m:listContains(m:list("google","facebook", "twitter","linkedin"), mtgReq.params['authType'])}">
      <sql:query var="googleUser" dataSource="${datasource}">SELECT * FROM account WHERE email=?
      <sql:param value="${mtgReq.params['email']}"/>
      </sql:query>
      <c:set target="${output}" property="user" value="${pageScope['user']}"/>
    </c:if>
</m:request>
</m:resource>

The existing function jstl can be copied and new functions can be created under the same tld

With the issue fixes, it can be released as mason 5.
