Use keyword arguments when defining method with boolean argument.

def setup_redis_env_url(prefix = nil, defaults = true)
Severity: Minor
Found in lib/mastodon/redis_config.rb by rubocop

This cop checks for places where keyword arguments can be used instead of boolean arguments when defining methods. respond_to_missing? method is allowed by default. These are customizable with AllowedMethods option.

Example:

# bad
def some_method(bar = false)
  puts bar
end

# bad - common hack before keyword args were introduced
def some_method(options = {})
  bar = options.fetch(:bar, false)
  puts bar
end

# good
def some_method(bar: false)
  puts bar
end

Example: AllowedMethods: ['some_method']

# good
def some_method(bar = false)
  puts bar
end

Prefer string interpolation to string concatenation.

cache_namespace = namespace ? namespace + '_cache' : 'cache'
Severity: Minor
Found in lib/mastodon/redis_config.rb by rubocop

This cop checks for places where string concatenation can be replaced with string interpolation.

The cop can autocorrect simple cases but will skip autocorrecting more complex cases where the resulting code would be harder to read. In those cases, it might be useful to extract statements to local variables or methods which you can then interpolate in a string.

NOTE: When concatenation between two strings is broken over multiple lines, this cop does not register an offense; instead, Style/LineEndConcatenation will pick up the offense if enabled.

Example:

# bad
email_with_name = user.name + ' '

# good
email_with_name = "#{user.name} "
email_with_name = format('%s ', user.name, user.email)

# accepted, line-end concatenation
name = 'First' +
  'Last'
