Class Method Details

.dump(variable, writeFlags = []) ⇒ Object

Emit a hash as the equivilant wexpr string, human readable or not. See possible writeflags in Expression. We also support :returnAsExpression which will return the expression, and not the string (for internal use).

	# first step, go through the variable and create the equivilant wexpr expressions
	expr = Expression::create_from_ruby(variable)
	
	if writeFlags.include? :returnAsExpression
		return expr
	end
	
	# then have it write out the string
	return expr.create_string_representation(0, writeFlags)
end

.load(str, flags = []) ⇒ Object

Parse Wexpr and turn it into a ruby hash Will thrown an Exception on failure
