View Source Kalevala.Brain.Variable (kalevala v0.1.0)
Handle variable data in brain nodes
Replaces variables in the format of ${variable_name}. Works with
a dot notation for nested variables.
Example:
The starting data
%{
channel_name: "rooms:${room_id}",
delay: 500,
text: "Welcome, ${character.name}!"
}With the event data
%{
room_id: "room-id",
character: %{
name: "Elias"
}
}Will replace to the following
%{
channel_name: "rooms:room-id",
delay: 500,
text: "Welcome, Elias!"

Functions
Dereference a variable path from a map of data
Detect variables inside of the data
Replace action data variables with event data
Replace detected and dereferenced variables in the data
Walk the resulting data map to convert keys from atoms to strings
Scan the value for a variable, returning Variable structs

Fails if any variables still contain an :error value, they were
not able to be dereferenced.
Walk the resulting data map to convert keys from atoms to strings
This is useful when sending the resulting data struct to action params
