types-to-schema

Converts Typed Clojure types to Prismatic Schemas for runtime checking

Obtaining

If you are using Leiningen, you can add

[types-to-schema "0.1.0"]

to your project.clj file and then run

lein deps

to download it from Clojars.

If you are using Maven:

<dependency>
  <groupId>types-to-schema</groupId>
  <artifactId>types-to-schema</artifactId>
  <version>0.1.0</version>
</dependency>

Usage

The main use case of this type to schema checker is in test files. You can assert that all test functions are using the types specified by core.typed like so:

(require '[types-to-schema.core :as tts])
(use-fixtures :once (tts/wrap-namespaces-fixture '[test.wrapping-namespace]))

For all namespaces in the vector, types to schema will then assert that these functions are receiving correctly typed input and giving correctly typed output.

Another use would be to create a Prismatic Schema for a core type like so:

(schema Number)
;=> java.lang.Number

You can then do validation on clojure values and variables like so:

(require '[schema.core :as s])
(s/validate (schema Number) 1)
;=> 1
