Pattern: Malformed end-line indentation

Issue: -

Description

Checks the indentation of the next line after a line that ends with a string literal and a backslash.

If EnforcedStyle: aligned is set, the concatenated string parts shall be aligned with the first part. There are some exceptions, such as implicit return values, where the concatenated string parts shall be indented regardless of EnforcedStyle configuration.

If EnforcedStyle: indented is set, it's the second line that shall be indented one step more than the first line. Lines 3 and forward shall be aligned with line 2. Here too there are exceptions. Values in a hash literal are always aligned.

Examples

# bad
def some_method
  'x' \
  'y' \
  'z'
end

my_hash = {
  first: 'a message' \
    'in two parts'
}

# good
def some_method
  'x' \
    'y' \
    'z'
end

my_hash = {
  first: 'a message' \
         'in two parts'
}
