Describe the bug

Hello,

I noticed that the sql-formatter.lua is not detecting the path correctly on MSYS2 when installed via node_modules. I believe the issue is here:

• https://github.com/stevearc/conform.nvim/blob/master/lua/conform/formatters/sql_formatter.lua#L7

Which should instead be similar to how prettier is detected (please refer to workaround below):

• https://github.com/stevearc/conform.nvim/blob/master/lua/conform/formatters/prettier.lua#L55

---

Using :ConformInfo you can see it doesn't use the *.cmd executable as expected for Windows machines:

Other formatters:
  clang_format ready (cpp, h, c) C:\msys64\ucrt64\bin\clang-format.EXE
  prettier ready (jsonc, json, markdown, typescript, typescriptreact, javascript, javascriptreact, html, css, yaml) C:
  \msys64\home\lemon\projects\liga\prototype\node_modules\.bin\prettier.cmd
  shfmt unavailable: Command 'shfmt' not found
  sql_formatter ready (sql) C:\msys64\home\lemon\.nvm\versions\node\v24.11.1\bin\sql-formatter
  stylua ready (lua) C:\msys64\usr\bin\stylua.EXE

Workaround

As a workaround (and possible) solution I had to add the following:

sql_formatter = {
      command = require("conform.util").from_node_modules(
        require("conform.fs").is_windows and "sql-formatter.cmd" or "sql-formatter"
      ),
    },

What is the severity of this bug?

minor (annoyance)

Steps To Reproduce

1. setup nvim on MSYS2.
2. add sql = { "sql_formatter" }, to conform setup.
3. open an *.sql file and attempt to format.
4. error observed in :ConformInfo and in logs.

Expected Behavior

Same behavior as prettier when detecting the executable from node_modules on MSYS2.

Minimal example file

vim.pack.add({
  "https://www.github.com/stevearc/conform.nvim",
})

require("conform").setup({
  formatters_by_ft = {
    sql = { "sql_formatter" },
  },
  format_on_save = {
    timeout_ms = 5000,
    lsp_format = "fallback",
  },
})

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,
        formatters_by_ft = {
          sql = { "sql_formatter" },
        },
      })
    end,
  },
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

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