How to disable warnings in .luarc.json?

[carsakiller]

The wiki explains the luarc file as well as the settings that can be used to disable warnings.

.luarc.json:

{
  "Lua": {
    "diagnostics.disable": {
      "default": [],
      "enum":[
        "trailing-space",
        "redefined-local",
        "redefined-label"
      ]
    },
    "workspace.checkThirdParty": false
  }
}

lua-language-server configuration:

{
  cmd = {"lua-language-server"},
  filetypes = {"lua"},

  on_attach = ...,
  handlers  = ...,
  capabilities = ...,
  

  settings = {
    Lua = {
      runtime = {
        -- Tell the language server which version of Lua you're using (most likely LuaJIT in the case of Neovim)
        version = 'LuaJIT',
      },
      diagnostics = {
        -- Get the language server to recognize the `vim` global
        globals = {'vim'},
      },
      workspace = {
        -- Make the server aware of Neovim runtime files
        library = vim.api.nvim_get_runtime_file("", true),
      },
      -- Do not send telemetry data containing a randomized but unique identifier
      telemetry = {
        enable = false,
      },
    },
  },

  root_dir = require"lspconfig.util".root_pattern{
    ".luarc.json", 
    ".luarc.jsonc", 
    ".luacheckrc", 
    ".stylua.toml", 
    "stylua.toml", 
    "selene.toml", 
    "selene.yml", 
    ".git",
    vim.fn.getcwd(),
  },
}

Your .luarc.json is formatted like a JSON schema. The schema provided details how your .luarc.json should be formatted, but can not be copied verbatim. Your .luarc.json should instead look like this:

{
  "diagnostics.disable": [
    "trailing-space",
    "redefined-local",
    "redefined-label"
  ],
  "workspace.checkThirdParty": false
}

You should receive autocompletion in the .luarc.json file in VS Code—that is what the schema is used for 🙂
