[eclipse-clp-users] Variable Attribute

Dear clp users,

  I am using variable attribute for some logic. To isolate my problem I have mentioned the below script.

:- lib(ic).
:- lib(ic_kernel).

has_my_attribute(_{eclipse:Attr}) ?-

The script does not compile and gives me an error:-

undefined variable attribute in add_attribute(_1841, Attr, eclipse)

The error is valid when the we add an attribute without the meta_attribute/2 to declare the attribute.  But in my case, has_my_attribute is a predicate declaration and should not have the error.

I wish to write a predicate to check if a variable has a particular user defined attribute or not.

Kindly help.

Thanks and Regards,

Shrirang Edgaonkar
