zig-visitor
Trying out the visitor pattern in zig
This repository contains a concrete implementation of the visitor pattern in the zig programming language.
As the object structure to visit, a simple arithmetic expression tree is chosen.
The rough outline of this tagged union is laid out in the file arith.zig. The
file visitor.zig describes the common functionality of Visitors for our
expression type.
Two basic Visitors are implemented: A simple expression evaluator (in
eval.zig) and a prefix notation outputter (prefix.zig).
