2. How to Extend¶

mecoSHARK can be extended by adding new processors for other programming languages.

All processors are stored in the mecoshark/processor folder. There are conditions, which must be fulfilled by the backends so that it is accepted by the mecoSHARK:

The *.py file for this backend must be stored in the mecoshark/processor folder.
It must inherit from threshold and implement the methods defined there.

The process of chosing the backend is the following:

Via sloccount the number of files get calculated that have the same programming languages
In each processor a threshold is defined () that shows when the processor will gets executed (e.g., 0.5 means that at least 50% of all files must have this programming language
Afterwards the processor calls process()

There are several important things to note:

If you want to use a logger for your implementation, get it via
```
logger = logging.getLogger("processor")
```
The execution logic is in the application class and explained here MecoSHARK.
