+Very low footprint JSON parser written in portable ANSI C.
+
+* BSD licensed with no dependencies (i.e. just drop the C file into your project)
+* Never recurses or allocates more memory than it needs
+* Very simple API with operator sugar for C++
+
+[![Build Status](https://github.com/json-parser/json-parser/actions/workflows/main.yml/badge.svg)](https://github.com/json-parser/json-parser/actions)
+
+_Want to serialize?  Check out [json-builder](https://github.com/udp/json-builder)!_
+
+Installing
+----------
+
+There is now a makefile which will produce a libjsonparser static and dynamic library.  However, this
+is _not_ required to build json-parser, and the source files (`json.c` and `json.h`) should be happy
+in any build system you already have in place.
+
+
+API
+---
+
+    json_value * json_parse (const json_char * json,
+                             size_t length);
+
+    json_value * json_parse_ex (json_settings * settings,
+                                const json_char * json,
+                                size_t length,
+                                char * error);
+
+    void json_value_free (json_value *);
+
+The `type` field of `json_value` is one of:
+
+* `json_object` (see `u.object.length`, `u.object.values[x].name`, `u.object.values[x].value`)
+* `json_array` (see `u.array.length`, `u.array.values`)
+* `json_integer` (see `u.integer`)
+* `json_double` (see `u.dbl`)
+* `json_string` (see `u.string.ptr`, `u.string.length`)
+* `json_boolean` (see `u.boolean`)
+* `json_null`
+
+
+Compile-Time Options
+--------------------
+
+    -DJSON_TRACK_SOURCE
+
+Stores the source location (line and column number) inside each `json_value`.
+
+This is useful for application-level error reporting.
+
+
+Runtime Options
+---------------
+
+    settings |= json_enable_comments;
+
+Enables C-style `// line` and `/* block */` comments.
+
+    size_t value_extra
+
+The amount of space (if any) to allocate at the end of each `json_value`, in
+order to give the application space to add metadata.
+
+    void * (* mem_alloc) (size_t, int zero, void * user_data);
+    void (* mem_free) (void *, void * user_data);
+
+Custom allocator routines.  If NULL, the default `malloc` and `free` will be used.
+
+The `user_data` pointer will be forwarded from `json_settings` to allow application
+context to be passed.
+
+
+Changes in version 1.1.0
+------------------------
+
+* UTF-8 byte order marks are now skipped if present
+
+* Allows cross-compilation by honoring --host if given (@wkz)
+
+* Maximum size for error buffer is now exposed in header (@LB--)
+
+* GCC warning for `static` after `const` fixed (@batrick)
+
+* Optional support for C-style line and block comments added (@Jin-W-FS)
+
+* `name_length` field added to object values
+
+* It is now possible to retrieve the source line/column number of a parsed `json_value` when `JSON_TRACK_SOURCE` is enabled
+
+* The application may now extend `json_value` using the `value_extra` setting
+
+* Un-ambiguate pow call in the case of C++ overloaded pow (@fcartegnie)
+
+* Fix null pointer de-reference when a non-existing array is closed and no root value is present
