# Description Fixes #12520 # User-Facing Changes Breaking change: Any operation parsing input with `PWD` to set the environment will now fail with `ShellError::AutomaticEnvVarSetManually` Furthermore transactions containing the special env-vars will be rejected before executing any modifications. Prevoiusly this was changing valid variables before while leaving valid variables after the violation untouched. ## `PWD` handling. Now failing ``` {PWD: "/trolling"} | load-env ``` already failing ``` load-env {PWD: "/trolling"} ``` ## Error management ``` > load-env {MY_VAR1: foo, PWD: "/trolling", MY_VAR2: bar} Error: nu:🐚:automatic_env_var_set_manually × PWD cannot be set manually. ╭─[entry #1:1:2] 1 │ load-env {MY_VAR1: foo, PWD: "/trolling", MY_VAR2: bar} · ────┬─── · ╰── cannot set 'PWD' manually ╰──── help: The environment variable 'PWD' is set automatically by Nushell and cannot be set manually. ``` ### Before: ``` > $env.MY_VAR1 foo > $env.MY_VAR2 Error: nu:🐚:name_not_found .... ``` ### After: ``` > $env.MY_VAR1 Error: nu:🐚:name_not_found .... > $env.MY_VAR2 Error: nu:🐚:name_not_found .... ``` # After Submitting We need to check if any integrations rely on this hack. |
