Generators reference

Every type for <gen>. Each one links to its full page.

`type`	Produces
`text`	A value from a set — uniform or by exact `percent`
`number`	An integer in a range, or a fixed-width digit string
`template`	Built-in realistic data and technical IDs
`file`	Values from your own files and CSV columns
`date`	A date or date-time in a range and format
`symbol`	A string of characters from a set or named alphabet
`regex`	A string matching a finite regular expression
`advanced_regex`	Regex, plus weighted choice between alternatives
`increment` / `decrement`	Rising and falling counters
`timeseries`	A time series — trend + seasonality + noise
`pattern`	A distribution shaped like a drawn curve
`http`	A value fetched over HTTP from a service you wrote
`pool`	One whole member of a `<pool>` — a record, not a value
`running`	A total accumulated down the column, not drawn

Cross-cutting attributes

These work on any generator (see Masks & case):

The next two only work when the generator produces something they can act on. Everywhere else they're ignored:

order= / cycle= — value order: random by default, or sequential. Ordering walks a list, so it applies to text and file. A number or a date draws from a range rather than a list, so it ignores the attribute.
anomaly= — push a share of the values out of range by multiplying them. The rule is about the value, not the generator: anything that reads as a number is multiplied, including a numeric string from text, file or a pack. Anything else — a name, a city — passes through unchanged and without a warning, because there is no "further out" for it. See Anomalies & missing values.
