I am try to fixing format buffer feature use mint format in the emacs-mint-mode issue.

After some debug, i get following error message instead.

Mint - Formatting files[

It wired, because, because sure i can run command successful in my konsole.

The above issue will happen if current PWD directory is not the project root

 ╰─ $ cd ~

In this case, mint format never format file.

So, the really issue is, we need a way to told formatter, where is the project root.

Following is some solution:

1. like crystal tool format, i can run any file outside project root.
2. mint format provided a command line option for specify the path of mint.json, then, when formatter do format,
   can pass this argument, for my case, format can do like this:
   mint format --config /home/common/Study/Mint/test_formatter/ /home/common/Study/Mint/test_formatter/source/Main.mint
3. Or support set a environment variable, where project root is, mint format can read it.

I workaround this issue in this PR with:

1. locate the project root with mint.json
2. goto project root, set this directory as default directory.
3. run code here.

Hi, i get a similiar issue when try to add mint-lang support to apheleia

As you can see, i added support for Crystal is in recent days, it quite easy, check this pr, and, it support almost all languages for now, even, nix.

But, when i try to add mint support for it, i get same(type) error as this.

Sat Oct 29 02:16:33 2022 :: /home/zw963/Crystal/play/mint-realworld-rework/source/
$ mint format --stdin

Unhandled exception: Error opening file with mode 'r': '/home/zw963/Crystal/play/mint-realworld-rework/source/mint.json': No such file or directory (File::NotFoundError)

Command failed with exit code 1.

Yes, the checker could not found the mint.json in the same folder of the opened file buffer, most other language format checker can handle this, but, always limit by this when i try to add auto save formatter for mint.

Thanks.
