This document defines reusable macro libraries. I'm sure this is useful for some usecases (e.g. editors) but I have a simpler one that goes into the direction of reusable form definitions.
In many of my forms date widgets are used: birthdate, start date, end date, ... Definining those widgets is nearly always the same, except the label. IMO it would make sense not only to have reusable macro libraries but also reusable widget libraries (renamed fd:macros to fd:library):
<fd:library>
<!-- reusable macros -->
<fd:macro define="product">
<fd:field id="name">
<fd:label>Name</fd:label>
<fd:datatype base="string"/>
</fd:field>
<fd:field id="price">
<fd:label>Price</fd:label>
<fd:datatype base="decimal"/>
</fd:field>
</fd:macro> <!-- reusable widgets -->
<fd:field name="project-date">
<fd:datatype base="date">
<fd:convertor>
<fd:patterns>
<fd:pattern>dd/MM/yyyy</fd:pattern>
</fd:patterns>
</fd:convertor>
</fd:datatype>
</fd:field></fd:library>
Syntax:
<fd:import prefix="..." uri="..."/>
Example:
<fd:import prefix="my-macros" uri="cocoon:/custom-fd-macros.xml"/>
<fd:field name="birthdate" extends="my-macros:project-date">
<fd:label>birthdate</fd:label>
</fd:field>Effective result:
<fd:field name="project-date">
<fd:label>birthdate</fd:label>
<fd:datatype base="date">
<fd:convertor>
<fd:patterns>
<fd:pattern>dd/MM/yyyy</fd:pattern>
</fd:patterns>
</fd:convertor>
</fd:datatype>
</fd:field>WDYT?
