The Attribute Grammar system can be used to annotate the production
rules of a grammar with inherited and synthesised attributes. The
values of the attributes can be determined while parsing/traversing
the abstract syntax tree and will give the semantic value of the tree.
.
The inherited attributes are values which are passed downwards through
the abstract syntax tree and the synthesised attributes are passed
upwards. Haskell expressions are used to describe the computation of
the attributes.
.
The uuagc compiler takes a set files in which the attribute grammar
is defined and generates a Haskell file that contains the data type
definitions corresponding to the grammar, semantic functions and
catamorphisms (functions that take a syntax tree and return the
semantic value of that tree)
.
The (Utrecht University) Attribute Grammar system is part of the
Haskell Utrecht Tools set.
