How to achieve variable reference

[astraw99]

Currently, there are 2 cases below will get error, how to achieve it?
Case 1:

let var1 = "key1"
let var2 = ./dir/${var1}/file.dhall

Case 2:

let SchedulerConfig = ./dir/file.dhall
let schedulerPlugin = "plugin1"
let config = SchedulerConfig.${schedulerPlugin}.makeSchedulerConfig

This is currently not possible in Dhall. Specifically, Dhall does not permit computed imports paths (either for file paths or URLs) nor does Dhall permit computed field names

[astraw99]

Got it. Did we (Dhall) have planning to support this?

[Gabriella439]

It's up to what people propose and standardize, but:

• the main reason why attributes currently don't support computed names is that it would complicate the type system
• the main reason why imports currently don't support computed paths is for security reasons
