Add --suggest-parser command line flag

See original GitHub issue

The --parser flag tells prettier which parser to use, overriding the auto-detection mechanism.

Could you add a similar --suggest-parser flag? This flag would tell prettier which parser to use if auto-detection fails.

I believe we need this for editor integration. The format-all plug-in for Emacs lets people format code in unsaved temporary buffers that have no filename. But in this case the plug-in knows which programming language mode is being used in Emacs for the temporary buffer, and can pass the information to prettier.

$ npx prettier --file-info foo.jsx
{ "ignored": false, "inferredParser": "babel" }

Is this what you are looking for?

(Seems we missed this flag in docs, cc @kachkaev https://github.com/prettier/prettier/pull/4341)
