Detailed Description

tag type to mark a tree or node to be emitted as yaml when using operator<<, with options.

For example:

Tree t = parse_in_arena("{foo: bar}");
std::cout << t; // emits YAML
std::cout << as_yaml(t, id); // emits YAML from nested node
std::cout << as_yaml(t, EmitOptions{}.flow_spc(true)); // emits YAML forcing spaces after flow commas
c4::yml::parse_in_arena
void parse_in_arena(Parser *parser, csubstr filename, csubstr yaml, Tree *tree, id_type node_id)
(1) parse YAML into an existing tree node. The filename will be used in any error messages arising du...
