feature request: Flag to prioritize locally installed formatter

[TL-Garcia]

Did you check existing requests?

• [X] I have searched the existing issues

Describe the feature

It would be nice to have a flag for the config that made conform prioritize locally installed formatters, instead of those installed by Mason

Provide background

Often we may find ourselves working in a project where we need to abide to certain formatting guidelines, and the tools used are not the same that we may personally use, for example:

In a Typescript project, we might personally choose to use BiomeJS, but we may find ourselves working in a project that expects us to run Prettier.

Right now, if we configured Conform like so: typescript = { "biome", "prettier" }

We would always run BiomeJS on the file, regardless of whether the project that we're working on already has a configuration file for Prettier, and has its binary installed as a dependency

What is the significance of this feature?

nice to have

I just found out the following snippet :

  formatters_by_ft = {
    python = function(bufnr)
      if require("conform").get_formatter_info("ruff_format", bufnr).available then
        return { "ruff_format" }
      else
        return { "isort", "black" }
      end
    end,

see https://github.com/stevearc/conform.nvim/blob/master/README.md#options

Haven't tried it on my own, but it looks like you could do similar to pick prettier if it's available + fallback to biome.

This is correct way to get that behavior. All the tools are available, you just have to write the glue code yourself.

@stevearc I have a similar question but about local vs global installs of the same tool.

If I have prettier installed globally, but it's also set up locally in the project with some extra plugins that I don't have installed globally, is there a way to prioritize using the local install rather than the global one?

EDIT: Nevermind! It seems as though this is just the default behavior of Conform! (I love this plugin)
