Expected Behaviour

I do not see a warning for duplicate-set-field in my project.

Actual Behaviour

Hi

Thanks for this plugin. I am getting warning for duplicate-set-field on this line:

function playdate.update()

and the duplicate is in the CoreLibs folder here:

...\PlaydateSDK\CoreLibs\__stub.lua

I have set the CoreLibs folder to be ignored by the code checker:

"Lua.diagnostics.libraryFiles": "Disable",

Is this the expected behaviour?

Reproduction steps

1. Install Lua language server plugin
2. Set "Lua.diagnostics.libraryFiles": "Disable",
3. Create main.lua
4. Add the line function playdate.update() to main.lua
5. Observe warning:

	"resource": "/e:/dev/miner/Source/main.lua",
	"owner": "_generated_diagnostic_collection_name_#0",
	"code": "duplicate-set-field",
	"severity": 4,
	"message": "Duplicate field `update`.",
	"source": "Lua Diagnostics.",
	"startLineNumber": 72,
	"startColumn": 10,
	"endLineNumber": 72,
	"endColumn": 25,
	"relatedInformation": [
		{
			"startLineNumber": 5,
			"startColumn": 10,
			"endLineNumber": 5,
			"endColumn": 25,
			"message": ".twopolefilter.s",
			"resource": "/e:/devtools/PlaydateSDK/CoreLibs/__stub.lua"
		}
	]
}]

Log File

No response

Riproduci l’avviso usando main.lua, la riga playdate.update() e l’impostazione Lua.diagnostics.libraryFiles configurata su Disable; confronta la diagnostica con CoreLibs/__stub.lua. Traccia il modo in cui le diagnostiche duplicate-set-field gestiscono i file di libreria e verifica il comportamento documentato dell’impostazione. Il lavoro è completato quando il comportamento osservato dell’avviso è coerente con la configurazione prevista.
