Includes:
Alignment, ConfigurableEnforcedStyle, MultilineExpressionIndentation
Defined in:

Overview

This cop checks the indentation of the method name part in method calls that span more than one line.

Examples:

EnforcedStyle: aligned (default)

# bad
while myvariable
.b
  # do something
end

# good
while myvariable
      .b
  # do something
end

# good
Thing.a
     .b
     .c

EnforcedStyle: indented

# good
while myvariable
  .b

  # do something
end

EnforcedStyle: indented_relative_to_receiver

# good
while myvariable
        .a
        .b

  # do something
end

# good
myvariable = Thing
               .a
               .b
               .c
