Add the debug logs

• [X] I have set log_level = vim.log.levels.DEBUG and pasted the log contents below.

Log file

Describe the bug

Doesn't seem to listen to my eslint settings.

What is the severity of this bug?

minor (annoyance)

Steps To Reproduce

1. Not sure, I could share my setup maybe?

Expected Behavior

Format according to prettier with eslint as linted format in mind

Minimal example file

No response

Minimal init.lua

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "--single-branch",
    "https://github.com/folke/lazy.nvim.git",
    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  {
    "stevearc/conform.nvim",
    config = function()
      require("conform").setup({
        log_level = vim.log.levels.DEBUG,
        -- add your config here
      })
    end,
  },
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

Additional context

One is before save (proper syntax on my formatting) The one with errors is what happen when I do :w

Update: might be related to how prettier formats the code. If I install Eslint LSP and do a EslintFixAll then the problem goes away and it formats correctly.

Managed to solve this issue, turns our that I wasn't looking at typescriptreact but just typescript...

For the documentation authors of this plugin: Is there any way to see what sort of file types are accepted? I mean, there are many ways to type "javascript":

• javascript
• JavaScript
• js
• JS
• Js

With react too:

• javascriptreact
• jsx
• JavaScript-React

???

@Saveljeffjonatan, how did you solve your problem?

In my case I have two LSP: typescript-language-server (ts server) and client-lsp (eslint). In ConformInfo I see that tsserver LSP is used. So by pressing <leader>cf code formatting not in according to .eslintrc. But in case use EslintFixAll formatting works correctly.

I finally just set empty list of formatters for typescript and javascript. After that formatting works correct.

I solved it by also adding typescriptreact and javascriptreact like this:

return {
  "stevearc/conform.nvim",
  event = { "BufReadPre", "BufNewFile" },
  config = function()
    local conf = require("conform")

    conf.setup({
      log_level = vim.log.levels.DEBUG,
      formatters_by_ft = {
        lua = { "stylua" },
        typescript = { { "prettierd", "prettier" } },
        typescriptreact = { { "prettierd", "prettier" } },
        javascript = { { "prettierd", "prettier" } },
        javascriptreact = { { "prettierd", "prettier" } },
        go = { "goimports", "gofmt" },

        ["*"] = { "codespell" },
        -- Use the "_" filetype to run formatters on filetypes that don't
        -- have other formatters configured.
        ["_"] = { "trim_whitespace" },
      },
    })

    vim.api.nvim_create_autocmd("BufWritePre", {
      pattern = "*",
      callback = function(args)
        require("conform").format({ bufnr = args.buf, lsp_fallback = true })
      end,
    })
  end,
}
