snakemake: access workdir from inside log_handler script

Question

I am trying to create a custom log_handler script that can save the workflow´s log as a JSON file inside {workdir}/logs. For that I need to know what is the current workdir but I cannot seem to access is from inside the script. Does anyone know how to access workdir from inside a log_handler script?

I have also tried using Path.cwd() from inside the script, but it did not work.

EDIT: to clarify this a bit more, snakemake allows to specify a --log-handler-script. According to the documentation:

Provide a custom script containing a function ‘def log_handler(msg):’. Snakemake will call this function for every logging output (given as a dictionary msg) allowing to e.g. send notifications in the form of e.g. slack messages or emails.

I am trying to write such a script (based on this) that parses the log messages and saves them in a file, ideally, inside the workdir. But for that, the script needs to be able to know the current workdir.

thanks,
