Frequently asked questions

Elps
Is there a list of builtin elps functions?
github.com/luthersystems/elps/lisp/builtins.go
Is there a version of the key-argument approach of function definition where all arguments are required?
You can combine key-argument with required fields, if you specify the required fields first. There is not a way to make key-arg fields required.
What does `default` do?
If the first argument is nil or false it will return the second argument, otherwise it will return the first.
Can you call go code from elps?
https://github.com/luthersystems/elps/blob/master/docs/embed.md discusses how to call Go from elps.
What is the difference between `[` and `(` ?
They are equivalent, and only cosmetic to make reading clearer.
How does `now` work in elps?
now is an RFC3339 timestamp that is set by shiroclient, and is common across multiple simulations of a transaction.
