This is a tiny type-checker for data in Nix, written in Nix.
|
|
|
|
Features:
|
|
|
|
* Checking of primitive types (`int`, `string` etc.)
|
|
* Checking polymorphic types (`option`, `list`, `either`)
|
|
* Defining & checking struct/record types
|
|
* Defining & matching enum types
|
|
* Defining & matching sum types
|
|
* Defining function signatures (including curried functions)
|
|
* Types are composable! `option string`! `list (either int (option float))`!
|
|
* Type errors also compose!
|
|
|
|
Lacking:
|
|
|
|
* Any kind of inference
|
|
* Convenient syntax for attribute-set function signatures
