# Description Work for #7149 - **Error `with-env` given uneven count in list form** - **Fix `with-env` `CantConvert` to record** - **Error `with-env` when given protected env vars** - **Deprecate list/table input of vars to `with-env`** - **Remove examples for deprecated input** # User-Facing Changes ## Deprecation of the following forms ``` > with-env [MYENV "my env value"] { $env.MYENV } my env value > with-env [X Y W Z] { $env.X } Y > with-env [[X W]; [Y Z]] { $env.W } Z ``` ## recommended standardized form ``` # Set by key-value record > with-env {X: "Y", W: "Z"} { [$env.X $env.W] } ╭───┬───╮ │ 0 │ Y │ │ 1 │ Z │ ╰───┴───╯ ``` ## (Side effect) Repeated definitions in an env shorthand are now disallowed ``` > FOO=bar FOO=baz $env Error: nu:🐚:column_defined_twice × Record field or table column used twice: FOO ╭─[entry #1:1:1] 1 │ FOO=bar FOO=baz $env · ─┬─ ─┬─ · │ ╰── field redefined here · ╰── field first defined here ╰──── ```
