Expected Behavior
Upon writing config files, I would expect that only the following configuration values would be written to disk:
Viper.Set()
Actual Behavior
Configuration values from mapped environment variables get written to configuration file if they have values whilst writing config files. This is unexpected because you generally only expect environment variables to effect the behaviour of executions for which they are set, but because of this, they will be persisted to disk and still act as the configuration values when the variables are no longer set.
In the Repl.it, use the shell to set
YEARS_SINCE_BORN
during execution. Even thoughage
is never explicitly set in the config, it gets written to the config file purely from the environment variable being set during execution.Steps To Reproduce
