# Description Due to #14249 loading `default_env.nu` before the user's `env.nu`, variables that were defined there were overriding: * Inherited values * Some values that were set in the Rust code, such as the `NU_LIB_PATH` when set using `--include-path`. This change checks to see if a variable already exists, uses its value if so, and sets the default value otherwise. Note: `ENV_CONVERSIONS` is still "forced" to a default value regardless, as it needs to run reliably. There's probably not much reason to inherit it, but I'm open to the idea if there's a use-case. # User-Facing Changes * Before: Variables that were set in `default_env.nu` always overrode those that were inherited from the parent process or set internally * After: Inherited and internal environment variables will take priority. # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting Will try to find a good place to mention this behavior in the Config chapter updates
