DateTime in logfile name?

[bmcdonnell-fb]

I can log RTT console output to a file using the rttConfig → decoders → timestamp option, such as shown in #740.

Is it possible to include the starting date and time in the filename, in something like yyyymmddhhmmss format? It would be good for reference, and prevents overwriting when starting a new session.

Hello @bmcdonnell-fb,

you can try following approach I found (not tested) https://stackoverflow.com/questions/75994247/visual-studio-code-launch-json-how-to-dynamically-generate-a-date-time-string

Best regards
