Thanks @nryant !

Can you please let me know what you would use this RTTM parser for?

I am asking because I am not happy with this whole pyannote-parser library and plan to get rid of this dependency in all other pyannote-xxx projects in the future.

Is this for pyannote-metrics to support RTTM files?
I have the (secret) plan to make it the default (and only supported) format by pyannote-metrics anyway.

Hi @hbredin ,

Yes, the intent was to support RTTM files for use with pyannote-metrics. I've actually been sitting on the code since last year and finally got around to committing it. But, if you're already planning to integrate RTTM parsing directly into pyannote-metrics, that makes perfect sense.

Just pushed pyannote/pyannote-metrics@7c6126f that does just that.

May I ask you to check if that suits your needs?
It is in the develop branch of pyannote-metrics for now but will be part of next release.

It relies on the new pyannote.database 1.6 that adds support for RTTM-based custom protocol that you might also find convenient.
