Custom functions

Example custom function

Once you’re comfortable creating simple functions you can create a function with custom syntax. We use this functionality to provide our counters that have their own syntax.

You can view our sqrl-redis-functions package for examples on how they were defined.

registry.registerCustom(function count(
  state: CompileState,
  ast: CustomCallAst
): Ast {
    /*
      In here `ast.source` is the raw source of the argumets to the count() call.
      For example count(BY Id) will give you `ast.source === "BY Id"`.
    */
}

You are responsible for parsing the features and any values inside the provided argument source.
