This is a set of functions for mock data creation.
No functions are exported, so use the entire Mock::Populate::* namespace when calling each.
Mock::Populate::*
Each function produces a list of elements that can be used as database columns. The handy collate() function takes these columns and returns a list of (arrayref) rows. This can then be processed into CSV, JSON, etc. It can also be directly inserted into your favorite database, with your favorite perl ORM.
collate()
$results = date_ranger(start => $start, end => $end, N => $n);
Return a list of N random dates within a range. The start and end dates and desired number of data-points arguments are all optional. The defaults are:
start: 2000-01-01 end: today (computed if not given) N: 10
The dates must be given as YYYY-MM-DD strings.
$modify = date_modifier($offset, @$dates);
Returns a new list of random future dates, based on the offset, and respective to each given date.
$results = time_ranger( stamp => $stamp, start => $start, end => $end, N => $n);
Return a list of N random times within a range. The start and end times and desired number of data-points arguments are all optional. The defaults are:
stamp: 1 (boolean) start: 00-00-00 end: now (computed if not given) N: 10
The times must be given as HH-MM-SS strings.
$results = number_ranger( start => $start, end => $end, prec => $prec, random => $random, N => $n)
Return a list of N random numbers within a range. The start, end, precision, whether we want random or sequential numbers and desired number of data-points arguments are all optional. The defaults are:
start: 0 end: 9 precision: 2 random: 1 N: 10
$results = name_ranger( gender => $gender, names => $names, country => $country, N => $n)
Return a list of N random person names. The gender, number of names and desired number of data-points arguments are all optional. The defaults are:
gender: b (options: both, female, male) names: 2 (first, last) country: us N: 10
$results = email_modifier(@people) # first.last@example.{com,net,org,edu}
Return a list of N email addresses based on a list of given names.
$results = distributor(type => $type, prec => $prec, dof => $dof, N => $n)
Return a list of N distribution values. The type, precision, degrees-of-freedom and desired number of data-points arguments are optional. The defaults are:
type: u (normal) precision: 2 degrees-of-freedom: 2 N: 10
This function uses single letter identifiers:
u: Normal distribution (default) c: Chi-squared distribution s: Student's T distribution f: F distribution
Given the type, this function accepts the following:
c: A single integer s: A single integer f: A fraction string of the form 'N/D' (default 2/1)
$results = shuffler($n, @items)
Return a shuffled list of $n items. The items and number of data-points arguments are optional. The defaults are:
n: 10 items: a b c d e f g h i j
$results = string_ranger(type => $type, length => $length, N => $n)
Return a list of N strings. The strings and number of data-points arguments are optional. The defaults are:
type: default length: 8 N: 10
* This function is nearly identical to the Data::SimplePassword rndpassword program, but allows you to generate a finite number of results.

$results = image_ranger(size => $size, N => $n)
Return a list of N 1x1 pixel images of varying byte sizes (not image dimension). The byte size and number of data-points are both optional.
The defaults are:
N: 10 size: 8
$rows = collate(@columns)
Return a list of lists representing a 2D table of rows, given the lists provided, with each member added to a row, respectively.
