This cop checks if the length of a block exceeds some maximum value. Comment lines can optionally be ignored. The maximum allowed length is configurable. The cop can be configured to ignore blocks passed to certain methods.

Duplicated Code

Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

Tuning

This issue has a mass of 56.

We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.

This cop checks the indentation of the first parameter in a method call. Parameters after the first one are checked by Style/AlignParameters, not by this cop.

Example:

# bad
some_method(
first_param,
second_param)

# good
some_method(
  first_param,
second_param)

This cop checks the indentation of the first parameter in a method call. Parameters after the first one are checked by Style/AlignParameters, not by this cop.

Example:

# bad
some_method(

second_param)

# good
some_method(
  first_param,

This cops checks the indentation of hanging closing parentheses in method calls, method definitions, and grouped expressions. A hanging closing parenthesis means ) preceded by a line break.

Example:

# good: when x is on its own line, indent this way
func(
  x,
  y
)

# good: when x follows opening parenthesis, align parentheses
a = b * (x +
         y
        )

# bad
def func(
  x,
  y
  )
end
