~200LoC. It has one function:

char *data = ... see c.txt ...;
struct Parse p;
json_get(&p, data, "['amendments'][10]");

The output of the JS-like 'intent' will be stored in p.str with length p.str_len. This will just point to an offset in the buffer you gave the parser. Optionally, you can call char *json_fixup_string(struct Parse *p) to get a formatted output.

Advantages:

• Very fast lexer & recursive descent parser
• Simple API
• No memory allocation required
• Correct (?) It parsed the entire bible.

Disadvantages:

• May not throw error on invalid syntax / invalid accesses
• Not written with memory safety in mind
• Doesn't parse into a tree for reformatting back to text
