Allow specifying prompt prefix via Environment variable collection #188969
Description
export interface EnvironmentVariableCollection {
/**
* A string that will be prepended to the existing prompt in the terminal. Keep it short and only use it if
* it's really needed, as it modifies all terminals, even those not related to the extension.
*
* Note this only applies if shell integration is enabled.
*/
promptPrefix: string;
}The idea is to use shell integration to apply this parameter. This can be used by Python extension to indicate an environment is activated in Powershell or fish where there is no other way to set the prompt.
