YOML - a DOM-like interface to YAML
====
YOML is a DOM-like interface to YAML, implemented as a wrapper around [libyaml](http://pyyaml.org/wiki/LibYAML).
It is a header-only library. Just include the .h files to use the library.
```
#include "yoml.h" /* defines the structures */
#include "yoml-parser.h" /* defines the parser */
static yoml_t *parse_file(FILE *fp)
{
yaml_parser_t parser;
yoml_t *doc;
yaml_parser_initialize(&parser);
yaml_parser_set_input_file(&parser, fp);
doc = yoml_parse_document(&parser, NULL);
yaml_parser_delete(&parser);
return doc;
}
static void dump_node(yoml_t *node, int indent)
{
size_t i;
switch (node->type) {
case YOML_TYPE_SCALAR:
printf("%*s[SCALAR] %s\n", indent, "", node->data.scalar);
break;
case YOML_TYPE_SEQUENCE:
printf("%*s[SEQUENCE] (size:%zu)\n", indent, "", node->data.sequence.size);
for (i = 0; i != node.data.sequence.size; ++i)
dump_node(node->data.sequence.elements[i], indent + 2);
break;
case YOML_TYPE_MAPPING:
printf("%*s[MAPPING] (size:%zu)\n", indent, "", node->data.mapping.size);
indent += 2;
for (i = 0; i != node.data.mapping.size; ++i) {
printf(%*s[KEY]\n", indent, "");
dump_node(node->data.mapping.elements[i].key, indent + 2);
printf(%*s[VALUE]\n", indent, "");
dump_node(node->data.mapping.elements[i].value, indent + 2);
}
indent -= 2;
break;
}
}
static void dump_file(FILE *fp)
{
yoml_t *doc = parse_file(fp);
if (doc == NULL) {
fprintf(stderr, "parse error!\n"); /* error info can be obtained from yaml_parser_t */
return;
}
dump_node(doc, 0);
yoml_free(doc);
}
```
