Python example listener - tags not supported

The Python example listener ( doesn’t seem to support tags (e.g. <Date>) or metadata tags (e.g. DUT’s <ID>) in the File Path. I’m guessing that the example code just needs some additional statements to make this information available. Any suggestions as to what needs to be added/changed in the example code to allow this?

Using PyCSV as the listener and File Path: Results/<Date>-test.csv
I get this error:

07:31:40.804 PyCSV Traceback (most recent call last):

Note: the same File Path works correctly when using the built in CSV listener


The tags are not currently supported by the example code. This is mostly to avoid overcomplicating it.

However, if everyone making a ResultListener plugin would need that anyway, maybe it would be natural to add it.

I have made a PR which changes it to using MacroString. Please let me know what you think.

Hi Rolf,

Works as expected - thanks for the prompt reply and support.
Much appreciated
