# Dev Guide


## Module Development 

### Make a new system.js file

In the [src/systems](src/systems) directory, create a new system file by copying and pasting a similar system to it; for example, `cp demonlord.js wfrp4.js`
You then need to go through all the functions in there and make sure that the correct data is set.

### Update TokenHelper
In [src/systems/TokenHelper.js](src/systems/TokenHelper.js), you need to add an `import {}` for your new system.

In the same file, in the setSystem() function, you need to wire in your system to the if/else block.

## Debugging

It's possible to debug on the Stream Deck, so you can do `console.log`. Just follow the instructions [from elgato here](https://developer.elgato.com/documentation/stream-deck/sdk/create-your-own-plugin/).  After editing the code for the plugin, you need to either refresh by refreshing the debug window, or by deselecting the current button, and selecting it again.

For getStats, getRolls you cannot change value

For the others, it depends on the system. For example:
in 5e, to get the appraise skill modifier, you do token.actor.data.data.skills?.[skill].total where 'skill' is 'apr'. So in the plugin, you have to set the value to 'apr'.

## Streamdeck

On the SD side: The plugin in windows is located at AppData/Roaming/Elgato/StreamDeck/Plugins/com.cdeenen.materialdeck.sdPlugin
In propertyinspector/js/common.js starting at line 1274 there's various functions that are used to get the relevant options to show up in the SD plugin. Each array element has a value and a name, you should keep the value the same, but the name can be whatever you like. I think you'll be able to figure out how to add stuff for wfrp by looking at the others.

To enable logging on the streamdeck, [follow these instructions](https://developer.elgato.com/documentation/stream-deck/sdk/create-your-own-plugin/) from Elgato.


## Module Deployment
Copy the new system.js and tokenHelper.js
