Export the logger for plugins

Export the logger for plugins

Environments

• Prettier Version: 1.19.1
• Running Prettier via: CLI
• Runtime: Node.js v10+
• Operating System: Windows, Linux, macOS

Steps to reproduce

• Just write a plugin ^^ (like @prettier/plugin-pug)
• Try to access the logger so that the CLI option --loglevel can take effect and can be used for the plugin
• Also benefit from chalk cli coloring

Expected behavior

The logger can be used/accessed in a plugin

Actual behavior

I had to write a logger by myself And this could not be managed by --loglevel 🙁

Old Issue

#3585 that was locked-due-to-inactivity 👎

and use prettier’s loggers

The thing is Prettier itself doesn’t have loggers. Its CLI does, but the CLI is a kind of separate thing. Think of it as of a separate package, which it (or a completely new CLI) should eventually become. It’s a Node program that uses Prettier API, whereas Prettier proper is an environment-independent library.

So even if we decide to support this use case, we can’t do it the way you did in your PR. The plugin helpers (util-shared) can’t use things like chalk or process.stdout. Pieces of the CLI code can’t leave the /cli directory and can’t be used in other directories.

Ok that’s a point I understand 😕
