7.1. Creating a junifer extension

Junifer is designed to be easily extensible. Through the use of a registry and decorators, you can easily add new functionality to junifer during runtime. This is done by creating a new Python module and importing it before running junifer.

A special consideration has to be made when using the code-less configuration. In this case, the with statement can be used to import a module or run a Python file.

In the following example, we instruct junifer to first import my_module and then run the my_file.py file.

with:
  - my_module
  - my_file.py

Thus, the code from my_file.py will be executed before running junifer. This is the ideal place to include junifer extensions.

Important

Some junifer commands will not consider files imported from files included in the with statement. If my_file.py imports my_other_file.py, some of the junifer commands will not consider my_other_file.py. Either place all the code in one file or add multiple files to the with statement.
