+visitor
+=======
+
+A tiny library to facilitate `visitor
+<https://en.wikipedia.org/wiki/Visitor_pattern>`_ implementation in Python
+(which are slightly peculiar due to dynamic typing). In fact, it is so small,
+you may just be better off copy & pasting the source straight into your
+project...
+
+
+Example use
+-----------
+
+A simple JSON-encoder:
+
+.. code-block:: python
+
+    from visitor import Visitor
+
+
+    class JSONEncoder(Visitor):
+        def __init__(self):
+            self.indent = 0
+
+        def escape_str(self, s):
+            # note: this is not a good escape function, do not use this in
+            # production!
+            s = s.replace('\\', '\\\\')
+            s = s.replace('"', '\\"')
+            return '"' + s + '"'
+
+        def visit_list(self, node):
+            self.indent += 1
+            s = '[\n' + '  ' * self.indent
+            s += (',\n' + '  ' * self.indent).join(self.visit(item)
+                                                   for item in node)
+            self.indent -= 1
+            s += '\n' + '  ' * self.indent + ']'
+            return s
+
+        def visit_str(self, node):
+            return self.escape_str(node)
+
+        def visit_int(self, node):
+            return str(node)
+
+        def visit_bool(self, node):
+            return 'true' if node else 'false'
+
+        def visit_dict(self, node):
+            self.indent += 1
+            s = '{\n' + '  ' * self.indent
+            s += (',\n' + '  ' * self.indent).join(
+                '{}: {}'.format(self.escape_str(key), self.visit(value))
+                for key, value in sorted(node.items())
+            )
+            self.indent -= 1
+            s += '\n' + '  ' * self.indent + '}'
+            return s
+
+
+    data = [
+        'List', 'of', 42, 'items', True, {
+            'sub1': 'some string',
+            'sub2': {
+                'sub2sub1': False,
+                'sub2sub2': 123,
+            }
+        }
+    ]
+
+    print(JSONEncoder().visit(data))
+
+
+
+Output::
+
+    [
+      "List",
+      "of",
+      42,
+      "items",
+      true,
+      {
+        "sub1": "some string",
+        "sub2": {
+          "sub2sub1": false,
+          "sub2sub2": 123
+        }
+      }
+    ]
