Currently every time Prettier adds another language, a lot of editor integrations have to release another version of their plugin to support it. This might be adding more language types, extensions, etc.

I'm wondering if we'd be able to support some kind of feature detection within Prettier that editor integrations can call and run more dynamically. Something along the lines of:

require('prettier').getSupportInfo();

Which might return:

{
  languages: [
    {
      language: "javascript",
      parsers: ["babylon", "flow"],
      ids: ["javascript", "javascriptreact"],
      extensions: [".js", ".jsx", ".mjs"]
    },
    {
      language: "typescript",
      parsers: ["typescript"],
      ids: ["typescript", "typescriptreact"],
      extensions: [".ts", ".tsx"]
    },
    ...
  ]
}

Would be nice to release this alongside Markdown support.

Love to get some feedback from some plugin maintainers on whether this kind of thing could be useful.
