Generate address
Generates a random postal address
Evaluation
This expression evaluates to a function of the form:
(seed) -> any
The function is consistent with generator semantics of the Random Data step.
Processing
Given a seed value, the function returns a pseudo-random dict value of the following form:
{
:street string,
:house_number string,
:postal_code string,
:city string
}
A concrete value might look like this:
{
:street 'Wintercress Terrace',
:house_number '7',
:postal_code '75146',
:city 'Greenham'
}
Street and city names are generated by combining elements from several pools of name fragments and words.
A large number of distinct combinations is possible.
House number and postal code are each generated to adhere to a given regular expression pattern.
The following regular expression syntax is supported
