Re: [rules-users] [rules-dev] Hold the Beans!
These seem like two good student projects, so I updated the wiki as
it's that time of year when students are picking up projects:

Please feel free to correct if some stuff I say is a bit high level or
needs more explanation.

The first aspect is to allow the type and the property accessors to
be
dynamically defined
declare Element
@type( nodeName )
@property( get( $1 ) )

Where $1 is the interpolation point for the passed property name. That
would then allow access to Dom Elements as though they were natural
facts. Same can be done for Maps, or similar constructs
declare Map
@type( get( "type" ) //the type is a key in the Map
@propert( get( $1 ) )
end
declare MyFact
@type( type ) //The type is field
@property( getProperty( $1 ) ) // all properties are via this getter
end
If you look at the expiremental FactTemplates you can see the guts of
how fields are accessed and figure out how to plumb this all up. Then
there is the RHS, which is a big more difficult, if you want the
properties supported as named fields, and not emulated getters.
