I am not sure what "cook up" means in English, but if you want to give
a string variable as keyword, write it between dollars in the EXTEND
statement:
let make_one_item_entry entrysym (keyword : string) =
let tmp = (Grammar.Entry.create Pcaml.gram entrysym) in
EXTEND
tmp: [ [ $keyword$ ] ]
;
END;
tmp;;
Grammar.Entry.print (make_one_item_entry "happy" "birthday");;
This is an undocumented feature.
