Validateur is a Clojure(Script) validation library inspired by Ruby's ActiveModel. Validateur is functional: validators are functions, validation sets are higher-order functions, validation results are returned as values.
Validateur is tested on Clojure 1.10 or later, ClojureScript 1.11 or later.
Validateur artifacts are released to Clojars.
If you are using Maven, add the following repository definition to your pom.xml:
<repository>
<id>clojars.org</id>
<url>http://clojars.org/repo</url>
</repository>With Leiningen:
[com.novemberain/validateur "2.6.0"]
With Maven:
<dependency>
<groupId>com.novemberain</groupId>
<artifactId>validateur</artifactId>
<version>2.6.0</version>
</dependency>
Please refer to the documentation guides for Validateur.
Our test suite has usage examples for each validator, built-in validation functions have docstrings.
Validateur uses Leiningen 2. Make sure you have it installed and then run tests against all supported Clojure versions and a recent release of ClojureScript using
lein all do clean, test
Then create a branch and make your changes on it. Once you are done with your changes and all tests pass, submit a pull request on Github.
