SourceMod JSON Extension

SourceMod JSON Extension

What is this?

This is a SourceMod extension that provides some methods for manipulating JSON data

Features

• Relies on YYJSON which A high performance JSON library written in ANSI C
• Supports querying and modifying using JSON Pointer
• Supports decoding and encoding (also with pretty format)
• Supports x64

How to build this?

clone project
mkdir build && cd build
python ../configure.py --enable-optimize --symbol-files --sm-path=YOU_SOURCEMOD_PATH --targets=x64,x86
ambuild

Native

• yyjson.inc

Binary files

• GitHub Actions

NOTES

• Not fully tested, some function may not work

Example

// Create JSONObject
YYJSONObject hJSONObject = new YYJSONObject();
hJSONObject.SetInt("int", 1);
hJSONObject.SetInt64("int64", "9223372036854775800");
hJSONObject.SetFloat("float", 2.0);
hJSONObject.SetBool("bool", true);
hJSONObject.SetString("str", "Hello World");
hJSONObject.SetNull("null");
delete hJSONObject;
/*

  "int": 1,
  "int64": 9223372036854775800,
  "float": 2.0,

  "str": "Hello World",
  "null": null

*/

// Create JSONArray
