## Link to GitHub Issue or related Pull Request, if one exists Fixes #245 ## Description of change Introduce patch groups. JSON schema now allows for a `"type": "group"`: ```json { "type": "group", "gameCode": "LDJ", "id": "timer-freeze", "name": "Timer Freeze Patches", "description": "Freezes various timers in the game." }, { "name": "Standard/Menu Timer Freeze", "description": "Freezes all non-premium area timers.", "caution": "", "gameCode": "LDJ", "type": "memory", "group": "timer-freeze", "patches": [ { "offset": 9962743, "dllName": "bm2dx.dll", "dataDisabled": "0F84", "dataEnabled": "90E9" } ] }, { "name": "Premium Free Timer Freeze", "description": "Freezes all premium area timers.", "caution": "", "gameCode": "LDJ", "type": "memory", "group": "timer-freeze", "patches": [ { "offset": 9111965, "dllName": "bm2dx.dll", "dataDisabled": "7E", "dataEnabled": "EB" } ] }, ``` In the UI, these will show up as tree nodes. The parent is not actually treated as a patch; e.g., its state is not saved to the patch manager config file; only the child patches states are managed, the parent's state only bubble up only in the UI. In downlevel versions of spice, group parents will show up as a patch of invalid type. Child patches will still show up as individual patches. ## Testing *how was the code tested?*
