How to reproduce the issue

Set up example formatting plugins:

init.lua:

local install_path = vim.fn.stdpath"data" .. "/site/pack/packer/opt/packer.nvim"

if vim.fn.empty(vim.fn.glob(install_path)) > 0 then
  vim.api.nvim_command("!git clone https://github.com/wbthomason/packer.nvim " ..
                         install_path)
  vim.api.nvim_command"packadd packer.nvim"
end

vim.cmd"packadd packer.nvim"

return require "packer".startup(function(use)
  use {"mhartington/formatter.nvim", config = function()
      require"formatter".setup {
        filetype = {
          go = {
            function()
              return {exe = "gofmt", stdin = true}
            end,
          },
        },
      }
    end
  }
  use {"rust-lang/rust.vim"} -- Fixes https://github.com/rust-lang/rust.vim/issues/460 over the built in version
end)

Case A:

src/test.rs:

fn main() {
println!("Hello World!");
}

$ nvim src/test.rs

:RustFmt

Case B:

test.go:

package main

import "fmt"

func main() {
fmt.Println("Hello World!")
}

$ nvim test.go

:Format

Expected behavior

(alacritty 0.10.1)

Case A:

fn main() {
    println!("Hello World!");
}

Case B:

package main

import "fmt"

func main() {
	fmt.Println("Hello World!")
}

Actual behavior

(foot 1.11.0)

This is very likely a bug in foot. Try the latest nightly of foot (if available) or build from master.

[fauu]

It's the same when built from master. I'll try reporting it to foot then.

[dnkl]

Looks like foot is sending replies to OSC-4 queries, but neovim isn't recognizing them?

[fauu]

Turns out the codes were being printed by a fish shell theme (Jomik/fish-gruvbox#7). The issue can be circumvented entirely by disabling the theme in non-interactive sessions:

if status is-interactive
        theme_gruvbox dark medium
end

[justinmk]

So why is this issue still open?

[dundargoc]

Yes, this seems unrelated to neovim. Let's close this. If I misunderstood something and this is in fact a neovim bug let us know and we can reopen this.
