FEEL Scala

Maven Central

A parser and interpreter for FEEL that is written in Scala (see What is FEEL?).

The FEEL engine started as a slack time project, grown into a community-driven project, and is now officially maintained by Camunda. 🚀

It is integrated in the following projects:

Features:

  • Full support for unary-tests and expressions
  • Including built-in functions
  • Extensible by custom functions and object mappers

Usage

Please have a look at the documentation. It describes how to write FEEL expressions (e.g. data types, language constructs, builtin-functions, etc.). Or, check out examples and learning resources here.

Want to try it out? Use the Playground to evaluate FEEL expressions.
