Generators

Events that create value.

Event Type	Behavior	Example(s)
Source	Generates a stream of values.	`=Source(100k)` `=Source(100k @ 3%)` `=Source(100k...110k @ 3%)`
Curve	Generates values based on a specified curve shape.	`=Curve('s', [365, 1k])`
Trend	From a list of values, generates a trended series of values.	`=Trend([12.1k,15.5k,13.6k,14.4k])` `=Trend([100,300,200,225])`
Extend	Extends a list of values using the slope between the last two values of the provided input.	`=Extend([1,2,3,10])`

Containers

Events that store value.

Event Type	Behavior	Example(s)
Pool	Collects values with no limit.	`=Pool(1.4m)` `=Pool(1.4m @ 1%)`
Pipe	Relays values downstream.	`=Pipe(0)` `=Pipe(0, 100)`
Bucket	Collects values up to a specified limit; overflow passes downstream.	`=Bucket(0, 500)`
Tipping Bucket	Collects values up to a limit; empties when limit is reached.	`=Tippingbucket(0, 500)`
Funnel	Releases a specific value from its store OR subtracts value from a downstream event each time it's triggered.	`=Funnel(100k, 200)` `=Funnel(0, -10k)`
Gate	Opens on a schedule, releasing all of the value it has collected. Any value not sent downstream is retained.	`=Gate(0)`
Silo	Stores value in a container; container has a minimum and maximum size. Excess value and overdraws are passed downstream.	`=Silo(100, [-50, 1k])` `=Silo(100, [-100,])`
Wheel	Stores value in a rotating list that follows a calendar.	`=Wheel(12)` `=Wheel(4, [250, 200, 175, 99])`
Base	Stores values in a list; sends the sum of those values to downstream events. Second argument specifies retention by cohort.	`=Base([] @ [95, 65, 54, 32, 23]%)`

Timers

Events that manage time.

Event Type	Behavior	Example(s)
Wait	Insert a delay.	`=Wait(7, 'days')` `=Wait(3, 'months')`
Block	Close off the flow of values for a certain amount of time.	`=Block(3, 'months')` `=Block(1, 'year')` `=Block(14, 'days')`

Transforms

Events that alter a value.

Event Type	Behavior	Example(s)
Transform	Modify the value received or convert units before relaying it downstream.	`=T('ceil')` `=T('floor')` `=T('abs')` `=T('round')` `=T('liters', 'gallons')` `=T('inches', 'meters')`

Conditionals

Events that test values.

Event Type	Behavior	Example(s)
If	Test a value and relay it if True.	`=If('>', 0)` `=If('gte', 5)`
Once	Test a value and relay it if True, but only once. False on all subsequent calls.	`=Once('>', 100k)`

Tiering & Scale

Events that perform matrix multiplication.

Event Type	Behavior	Example(s)
Tiering	Define a set of tiers and identify which tier an inputted number belongs to.	`=Tiering([5, 10, 20])`
Scale	Define breakpoints; given a value, split it into those breakpoints.	`=Scale([150, 250, 500])`

Tunnels

Events that connect models.

Event Type	Behavior	Example(s)
Tunnel	Connect to an event from a different model.	`=Tunnel("SaaS Marketing Model::Total Marketing Budget")`

Requests

Events to fetch remote data.

Event Type	Behavior	Example(s)
Request	Make a `GET` or `POST` request for JSON or CSV data.	`=Request('get', 'https://api.example.com/x.json')`
Querystring	Parse and store a querystring.	`=Querystring('lat=40&lon=-101')`
Parser	Use a JSONPath expression to parse the output of a Request.	`=Parser('$..coordinates.lat')`
