Pd
FeaturesPd
features (see constituent
structure) require special
handling. positionFeature/2
in Nmacros
declares the publically accessible Pd
features:
positionalFeature(apos,X,hfApos(X)). positionalFeature(adjunct,X,posInfoAdjunct(X)). positionalFeature(compl,X,posInfoCompl(X)). positionalFeature(indirectObject,X,posInfoIDO(X)).
At compile time, Nmacros
looks for goals of the form:
X has_feature P |
where P
is a positional feature to be rewritten by
translateNR/5
:
translateNR(has_feature,2,has_feature(X,F),PosGoal,[]) :- nonvar(F), positionalFeature(F,X,PosGoal), !.
For example:
X has_feature apos
|
