Date: Wed, 23 Oct 2024 16:52:30 +0000 [thread overview]
Message-ID: <DS7PR20MB46710FEF0C6CD8458A272603BE4D2@DS7PR20MB4671.namprd20.prod.outlook.com> (raw)
In-Reply-To: <DS7PR20MB46716809EF26589A32E14C0FBE4D2@DS7PR20MB4671.namprd20.prod.outlook.com>
I have a new workaround, which is to configure conda to not change the prompt.
conda config --set changeps1 false
As discussed elsewhere:
Do not modify prompt by default #10928
https://github.com/conda/conda/issues/10928
I generally would not want to do this in normal interactive use, but in this context, am going to proceed.
I think it is preferable to trying to improve on prompt tracking. That appears just to lead to more convolutions.
Thoughts?
