commit https://github.com/vim/vim/commit/595e64e259faefb330866852e1b9f6168544572a Author: Bram Moolenaar <Bram@vim.org> Date: Sun Feb 7 19:19:53 2016 +0100 patch 7.4.1279 Problem: jsonencode() is not producing strict JSON. Solution: Add jsencode() and jsdecode(). Make jsonencode() and jsondecode() strict.

/* json.c */
char_u *json_encode(typval_T *val, int options);
char_u *json_encode_nr_expr(int nr, typval_T *val, int options);
int json_decode_all(js_read_T *reader, typval_T *res, int options);
int json_decode(js_read_T *reader, typval_T *res, int options);
int json_find_end(js_read_T *reader, int options);
/* vim: set ft=c : */
