To add a new rule, a YAML Rule file should be created inside the analyser/rules_specifications folder. The YAML file name should be unique and it will be equal to the name of the rule (as much as possible).
The content of the file should follows the YAML Rule Specification format.
If a more advanced rule needs a custom python logic, a custom Pipe can be created.
To do that, a folder with the name of the rule should be created inside the analyser/core/pipes/rules_specific_pipes folder.
A python file should be created inside the newly created folder. This file should contain a class which inherits from the Pipe base class. See the Pipe base class chapter to understand how the base Pipe class works and how to create a custom pipe from it.
The custom Pipe class should be imported inside the __init__.py of the analyser/core/pipes/rules_specific_pipes so that it can be found by the Assembler (See Architecture).
Once the custom pipe well created, it can be used in the YAML Rule Specification by setting its class name as the value of the type field.
