Core (std)

Std

Call Function

Calls the supplied handler function using list of arguments supplied to inputs.

Or Else

Return first if it is not null, otherwise second.

Switch

Propagates the first value if the first trigger is called, otherwise propagates the second value.

Generate UUID

Generates a UUID (universally unique identifier).

Delay

Pauses execution for delay for ms. All execution is blocked during this time.

Cache

Relay makes the input value available on the value output. Since this is an executable function, the input value will be cached, so Relay can be used for caching of expensive computations.

Log (std)

Write input to the Log panel.

Format Log

Logs a formatted string to the log window, letting you replace {{input name}} with any input value.

To String

Converts any input type to a String. This function is not suitable for serialization; use for example Json.Stringify instead.

If

If input is true, the then trigger is executed, otherwise the else trigger is executed. value contains the value of input.

Choose

A non-triggable alternative to Std If, which can be used to choose one of two values based on whether predicate is true or false.

Match

Switches on the values provided to the cases parameter, which accepts a list of values. For each value, an output trigger is created, which is triggered when the value property matches that list item.

Type Of

Returns the type of value as a String.

For

Count can be used to make tranditional for-loops. The on count trigger will execute `iterations` number of times. The donetrigger will execute when the loop is completed. The reset input trigger is used to start the loop.

For Each

For can be used to make a traditional for-each-loop. The on count trigger will execute once per item in the items input, which expects a list.

Stop

Used to explicitly stop execution. The exit code input is currently not used for anything user-facing, but might be exposed in the future.

Is Number

Spawn

Spawns a new process by copying the current one. The current process continues through the done output trigger, while the forked process continues throug the spawned output trigger, but in a new process.

Merge
