end

#map! {|self| ... } ⇒ self

Uses a block to transform all Patterns in the list

Parameters:

  • map_includes (Boolean) —

    should include patterns be mapped?

Yields:

  • (self) —

    invokes the block with self for modification

Returns:

  • (self)

def map!(*)
    self
end

#run_tests ⇒ Boolean

Runs the unit tests, recursively

Returns:

  • (Boolean) —

    If all test passed return true, otherwise false

def run_tests
    true
end

#start_pattern ⇒ self

To aid in Linters all Patterns support start_pattern which return the pattern for initial match, for a single match pattern that is itself

Returns:

  • (self) —

    This pattern

end

#to_tag ⇒ Hash

converts a PatternBase to a Hash representing a textmate rule

Returns:

  • (Hash) —

    The pattern as a textmate grammar rule

  • (Hash) —

    The hash it was constructed with
