class SyntaxSuggest::RipperErrors
Capture
parse errors from Ripper
Prism returns the errors with their messages, but Ripper does not. To get them we must make a custom subclass.
Example:
puts RipperErrors.new(" def foo").call.errors # => ["syntax error, unexpected end-of-input, expecting ';' or '\\n'"]
