Configuration

The default configuration of mdsf aims to as sane as possible. For that reason the default formatter for each language is the one most people have installed.

If you are interested in customizing which formatter is run, you can create a new mdsf configuration file by running

mdsf init

mdsf supports running multiple formatters on the save code snippet.

{
  "languages": {
    // Only run `ruff` on Python snippets,
    "python": "ruff",
    // Run `usort` on file and then `black`
    "python": ["usort", "black"],
    // Run `usort`, if that fails run `isort`, finally run `black`
    "python": [["usort", "isort"], "black"],

    // Formatters listed under "*" will be run on any snippet.
    "*": ["typos"],

    // Formatters listed under "_" will only be run when there is not formatter configured for the file type OR globally ("*").
    "_": "prettier"
  }
}
