NAME¶
Ast_iterator - Ast_iterator.iterator enables AST inspection using open recursion.
Module¶
Module Ast_iterator
Documentation¶
Module Ast_iterator
: sig end
Ast_iterator.iterator enables AST inspection using open recursion. A typical mapper would be based on Ast_iterator.default_iterator , a trivial iterator, and will fall back on it for handling the syntax it does not modify.
Warning: this module is unstable and part of Compiler_libs .

}
A iterator record implements one "method" per syntactic category, using an open recursion style: each method takes as its first argument the iterator to be applied to children in the syntax tree.
val default_iterator : iterator
A default iterator, which implements a "do not do anything" mapping.
