Deprecating Personal Config

Summary

This RFC deprecates the personal config that is .eslintrc files on home directory.

Motivation

Since 6.0.0, ESLint doesn't load plugins/configs/parsers from the global installation even if it's not a part of a project such as the personal config. This is inconvenient for the personal config. But, in #28 discussion, we confirm that we don't want to use the global installation.

We don't recommend to use global-installed ESLint. But the personal config has encouraged to use it.

Detailed Design

Three steps:

  1. Soft deprecation: Update our documentation to announce to deprecate the personal config on the next minor release.
  2. Hard deprecation: Add the deprecation warning of the personal config on ESLint 7.0.0.
    • ESLint shows a warning when it loaded the personal config.
    • ESLint shows a warning when it ignored the personal config (Currently, it ignores .eslintrc files on home directory if a project directory is in home directory and the project has .eslintrc files.)
  3. Removal: Remove the personal config functionality on ESLint 8.0.0.
    • ESLint no longer loada the personal config even if the project config was not found.
    • ESLint no longer ignores the config files on home directory even if the project config was found.

Documentation

Drawbacks

It will make people inconvenient to lint standalone files.

Backwards Compatibility Analysis

Yes, this is a breaking change.

To lint standalone files, people have to have a dummy project directory such as sandbox.
