Command-line Interface

epsilon-clj put emphasis on being able to integrate generation workflow into your own. Having a library that does not have a CLI introduces some complexities when you want to take advantage of your CI/CD, and thus epsilon-clj should avoid being that library.

This page serves as a reference guide on different commands and options you can use.

!!! info For most up-to-date commands and options, use -h or --help option.

It is also assumed that you have also installed epsilon-clj. If not, check out Installation page.
