{- This file provides a central `Prelude` import for the rest of the library to
|
|
|
|
use so that the integrity check only needs to be updated in one place
|
|
|
|
whenever upgrading the interpreter.
|
|
|
|
|
|
|
|
This allows the user to provide their own Prelude import using the
|
|
|
|
`DHALL_PRELUDE` environment variable, like this:
|
|
|
|
|
|
|
|
```
|
|
|
|
$ export DHALL_PRELUDE='https://prelude.dhall-lang.org/package.dhall sha256:...'
|
|
|
|
```
|
|
|
|
|
|
|
|
Note that overriding the Prelude in this way only works if this repository
|
|
|
|
is imported locally. Remote imports do not have access to environment
|
|
|
|
variables and any attempt to import one will fall back to the next available
|
|
|
|
import. To learn more, read:

|
|
|
|
|
|
|
|
This file also provides an import without the integrity check as a slower
|
|
|
|
fallback if the user is using a different version of the Dhall interpreter.
