GDY Schema Tutorial

This tutorial will show you how to set up your IDE to help write GDY files.

The GDY Schema defines all the required and optional properties that can be used to create games. Find your IDE below and follow the instructions to set up the schema validator!

You can either download the schema locally or reference it from the github repository

Visual Studio Code

  • Install the redhat.vscode-yaml extension from the visual studio code marketplace.

This extension allows json schema files to be used to add syntax support for yaml files.

  • Edit the your workspace settings to add the following keys:

     "editor.insertSpaces": true,
     "editor.tabSize": 2,
     "editor.quickSuggestions": {
       "other": true,
       "comments": false,
       "strings": true
     "editor.autoIndent": "none",
   "yaml.schemas": {
     "gdy-schema.json": "[path to your gdy files]/*.yaml"


PyCharm has a feature for YAML validation with JSON schema files built in.

In settings navigate to Languages And Frameworks -> Schemas and DTDs -> JSON Schema Mappings

You will need to the schema location to either the schema location on github

or download the schema file locally and point to it on your local machine.

You will also need to set a Filepath Pattern to point to the location you are storing your GDY YAML files.
