VS Code Extension

MSK Core (FiveM) IntelliSense adds autocompletion, signatures, hover documentation and type checking for the whole MSK.* API to Visual Studio Code and compatible editors.

The definitions cover msk_core v4.1.0: the MSK handle, every module namespace, the flat functions, the backwards compatibility aliases and the common export proxies.

Installation

Editor	Where to get it
Visual Studio Code	VS Code Marketplace, or search for MSK Core in the Extensions view
Cursor, VSCodium, Windsurf	Open VSX, or search for MSK Core in the Extensions view

You can also install it from the command palette (Ctrl+P):

ext install musiker15.msk-core-lua

The Lua Language Server (sumneko.lua) is installed automatically as a dependency.

FiveM natives

The extension only covers MSK.*. For the FiveM natives install communityox.cfxlua-vscode-cox or the fivem-lls-addon as well. Both work side by side with this extension.

Setup

There is nothing to configure. The extension adds its definitions to Lua.workspace.library in your user settings, so they work in every project.

Your resource only needs the usual import in its fxmanifest.lua:

lua54 'yes'

shared_script '@msk_core/import.lua'

For workspaces that contain a fxmanifest.lua, the extension also sets Lua.runtime.version to Lua 5.4, but only if no runtime is configured there yet. Other Lua projects are not touched.

Settings

Setting	Default	Effect
mskCore.enableLibrary	true	Adds the definitions to Lua.workspace.library.
mskCore.setRuntime	true	Sets Lua 5.4 for workspaces with a fxmanifest.lua that have no runtime set yet.

Commands in the command palette:

• MSK Core: Reload definitions
• MSK Core: Show definitions path

When you uninstall the extension, it removes its library entries from your settings again.

Client and server

Where the signatures differ, the client variant is the main signature and the server variant is shown as an overload. On the server almost every UI function takes the target player ID as its first argument:

MSK.Notification({ title = 'Title', message = 'Text', type = 'success' })         -- Client
MSK.Notification(source, { title = 'Title', message = 'Text', type = 'success' }) -- Server

Old parameter forms that are still supported but deprecated are shown struck through in the suggestion list.

Unknown fields

import.lua forwards every name that is neither a module nor an alias to exports.msk_core:<Name>. The common exports are typed, but not every possible one, so a rarely used export can be reported as undefined-field even though it works at runtime.

If that happens, please open an issue so the export gets added. You can also turn the check off in your settings:

"Lua.diagnostics.disable": ["undefined-field"]

The extension is open source: MSK-Scripts/msk_core-vscode. Issues and pull requests are welcome.
