Constructor Details

#initialize(generator, code: '', &block) ⇒ Arbitrary

Creates new arbitrary code.

Parameters:

• code (String) (defaults to: '') —

  The arbitrary code string. Indentation is added to the beginning of each line.

# File 'lib/parlour/rbs_generator/arbitrary.rb', line 17

def initialize(generator, code: '', &block)
  super(generator, '')
  @code = code
  yield_self(&block) if block
end

#code ⇒ Object

Returns arbitrary code string.

def code
  @code
end

Instance Method Details

#==(other) ⇒ Boolean

Returns true if this instance is equal to another arbitrary code line.

Parameters:

• other (Object) —

  The other instance. If this is not a Parlour::RbsGenerator::Arbitrary (or a subclass of it), this will always return false.

Returns:

• (Boolean)

# File 'lib/parlour/rbs_generator/arbitrary.rb', line 33

def ==(other)
  Arbitrary === other && code == other.code
end

#describe_attrs ⇒ Object

# File 'lib/parlour/rbs_generator/arbitrary.rb', line 84

def describe_attrs
  [:code]
end

#generate_rbs(indent_level, options) ⇒ Array<String>

Generates the RBS lines for this arbitrary code.

Parameters:

• indent_level (Integer) —

  The indentation level to generate the lines at.

• options (Options) —

  The formatting options to use.

Returns:

• (Array<String>) —

  The RBS lines, formatted as specified.

# File 'lib/parlour/rbs_generator/arbitrary.rb', line 48

def generate_rbs(indent_level, options)
  code.split("\n").map { |l| options.indented(indent_level, l) }
end

#merge_into_self(others) ⇒ void

This method returns an undefined value.

Given an array of Parlour::RbsGenerator::Arbitrary instances, merges them into this one. This particular implementation always throws an exception, because #mergeable? is always false.

Parameters:

• others (Array<RbsGenerator::RbsObject>) —

  An array of other Parlour::RbsGenerator::Arbitrary instances.

# File 'lib/parlour/rbs_generator/arbitrary.rb', line 79

def merge_into_self(others)
  raise 'arbitrary code is never mergeable'
end

#mergeable?(others) ⇒ Boolean

Given an array of Parlour::RbsGenerator::Arbitrary instances, returns true if they may be merged into this instance using #merge_into_self. This is always false.

Parameters:

• others (Array<RbsGenerator::RbsObject>) —

  An array of other Parlour::RbsGenerator::Arbitrary instances.

Returns:

• (Boolean) —

  Whether this instance may be merged with them.

# File 'lib/parlour/rbs_generator/arbitrary.rb', line 63

def mergeable?(others)
  false
end
