How do I configure which languages eslint is used for?

By default, we have:

I see that here we have probe and validate options.

but the settings keys have dots in them -- how does this work in lua, since keys aren't allowed to have dots, as strings are not valid object keys?

update, the syntax I was looking for was [], but that wasn't enough:

for _, serverName in ipairs(servers) do
  local server = lsp[serverName]

  if (server) then

    -- ...

    elseif (serverName == 'eslint') then 
      server.setup({
        settings = {
          ["eslint.probe"] = { "javascript", "typescript", "typescript.glimmer", "javascript.glimmer" },
          ["eslint.validate"] = { "javascript", "typescript", "typescript.glimmer", "javascript.glimmer" },
        },
        on_attach = function(client, bufnr)
          vim.api.nvim_create_autocmd("BufWritePre", {
            buffer = bufnr,
            command = "EslintFixAll",
          })
        end,
      })

I believe those settings are VSCode-specific. If you don't want to spawn the eslint language server for certain filetypes you can override the default filetypes when setting up the server:

require("lspconfig").eslint.setup {
  filetypes = { "javascript" }
}

Perfection! thanks! I now have this:

    elseif (serverName == 'eslint') then 
      server.setup({
        filetypes = { 
          "javascript", "typescript", 
          "typescript.glimmer", "javascript.glimmer", 
          "json", 
          "markdown" 
        },
        on_attach = function(client, bufnr)
          vim.api.nvim_create_autocmd("BufWritePre", {
            buffer = bufnr,
            command = "EslintFixAll",
          })
        end,
      })
    else

and everything is better! 🎉
