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

Log file

Log file: /Users/rinaldi/.local/state/nvim/conform.log
Formatters for this buffer:
LSP: eslint, vtsls
prettier ready (html, javascript, jsonc, markdown.mdx, typescriptreact, typescript, graphql, handlebars, less, scss, json, yaml, javascriptreact, css, vue, markdown) /Users/rinaldi/work/web-react/node_modules/.bin/prettier

Other formatters:
fish_indent ready (fish) /opt/homebrew/bin/fish_indent
shfmt ready (sh) /Users/rinaldi/.local/share/nvim/mason/bin/shfmt
stylua ready (lua) /Users/rinaldi/.local/share/nvim/mason/bin/stylua

Describe the bug

I would expect conform to respect Prettier's printWidth setting which automatically would wrap the code/text given a max width/length, but it doesn't somehow.

What is the severity of this bug?

tolerable (can work around it)

Steps To Reproduce

mkdir test # create a test dir
cd test # cd into it
echo "{"printWidth": 50}" > .prettierrc # create a prettier config setting max width to 50
echo "{"private": true}" > package.json # startup npm
npm i prettier -D # install prettier under `devDependencies`
nvim index.js # open a javascript file in nvim

Just start typing until the text is longer than 50 characters and run the formatter.

Expected Behavior

On format the printWidth setting should be respected.

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

It looks like you have pasted some of the contents of :ConformInfo, but there are no actual logs. The logs are important because they will display what command was actually being run. You should find the prettier command that conform is issuing and try running it directly yourself on the command line. Usually this helps narrow down the cause of the problem.
