Diagnostics error level configuration

[soutaro]

All diagnostics are reported in one of two levels, error and ignored. I plan to add more levels and let users configure theirselves.

Configuration DSL

Giving a table from diagnostics classes to levels would be sufficient.

D = Steep::Diagnostics

code_config = D.default.merge({ D::Ruby::NoMethod => :error, D::Ruby::UnexpectedBlockGiven => :warning })

target :lib do
  code_diagnostics code_config
end

• Users can find all possible keys under Steep::Diagnostics::Ruby module. 👍
• Renaming class names would confuse the users. 👎
  • Autoloading can help adding warning messages and providing a compatibility mode.

Default configurations

I want to provide three default configurations of default, lenient, and strict.

That would be really great 👍 I wish we had an ability to silence some errors (e.g., Ruby::UnsupportedSyntax instead of ignoring the whole file).
