Description
This module provides staticDhallExpression which can be used to resolve
all of an expression’s imports at compile time, allowing one to reference
Dhall expressions from Haskell without having a runtime dependency on the
location of Dhall files.
For example, given a file "./Some/Type.dhall" containing
< This : Natural | Other : ../Other/Type.dhall >
... rather than duplicating the AST manually in a Haskell Type, you can
do:
Dhall.Type
(\case
UnionLit "This" _ _ -> ...
UnionLit "Other" _ _ -> ...)
$(staticDhallExpression "./Some/Type.dhall")This would create the Dhall Expr AST from the "./Some/Type.dhall" file
at compile time with all imports resolved, making it easy to keep your Dhall
configs and Haskell interpreters in sync.
