Useless assignment to variable - opaque. Use _ or _opaque as a variable name to indicate that it won't be used.
Open

    scheme, userinfo, @host, port, registry, @mount_root, opaque, query, fragment = URI.split(URI::DEFAULT_PARSER.escape(@settings[:uri]))

Checks for every useless assignment to local variable in every scope. The basic idea for this cop was from the warning of ruby -cw:

assigned but unused variable - foo

Currently this cop has advanced logic that detects unreferenced reassignments and properly handles varied cases such as branch, loop, rescue, ensure, etc.

NOTE: Given the assignment foo = 1, bar = 2, removing unused variables can lead to a syntax error, so this case is not autocorrected.

Safety:

This cop's autocorrection is unsafe because removing assignment from operator assignment can cause NameError if this assignment has been used to declare local variable. For example, replacing a ||= 1 to a || 1 may cause "undefined local variable or method `a' for main:Object (NameError)".

Example:

# bad

def some_method
  some_var = 1
  do_something
end

Example:

# good

def some_method
  some_var = 1
  do_something(some_var)
end

Useless assignment to variable - scheme. Use _ or _scheme as a variable name to indicate that it won't be used.
