`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
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.09
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
