`nixos-option` basically handles two cases: the given option is either a valid option defined using `mkOption` or an attribute set which contains a set of options. If none of the above cases is valid, `$1` is invalid. Unfortunatley the script interpreted invalid options as an attribute set which rendered shell failures when trying to evaluate the arguments. First of all, `if names=$(attrNames ...)` resulted in `<PRIMOP>` as `attrNames` simply evaluated `builtins.attrNames $result` which results in a non-applied function with `$result` being empty. Trying to map over this string using `nixMap` while applying `escapeQuotes` causes the bash error as `eval echo "<PRIMOP>"` is invalid syntax. Explicitly checking if `$result' contains a value (do we have an attribute set?) and otherwise returning a warning and asking if $option exists fixes the problem. Fixes #48060 |
