libmocha

A C library to parse mocha an elegant configuration language for both humans and machines.

Example

This program output all tokens in text.

#include <mocha.h>
#include <stdio.h>

int main(void) {
  const char* text =
      "defaults: { \
         user_id: 0 \
         start_id: user_id \
        } \
        hanna: { \
        name: 'hanna rose' \
        id: @:defaults:user_id \
        inventory: ['banana' 12.32] \
        }";

  mocha_object_t obj;
